Electrosurgical units (ESUs), commonly known as electrosurgical equipment, are widely used in surgical procedures. By generating heat through high-frequency electric current, they enable precise tissue cutting and effective hemostasis. Due to their ease of use, rapid cutting, and reliable bleeding control, ESUs have become indispensable tools in operating rooms, particularly in general surgery, gynecology, and colorectal surgery ^[1]. With the advancement of medical technology, the performance of electrosurgical units continues to improve, significantly enhancing both safety and efficiency, and supporting minimally invasive surgery and faster postoperative recovery.

 

Compared with traditional scalpels, electrosurgical units can effectively reduce intraoperative blood loss, shorten surgery duration, and lower the risk of postoperative complications. Studies have shown that proper use of ESUs can significantly improve surgical outcomes. In one study involving 160 surgical patients, the observation group receiving care with standardized electrosurgical unit procedures had an average surgery time of 132.9 minutes, intraoperative blood loss of 43.7 mL, and nursing satisfaction of 95.1%, all of which were superior to the conventional care group (P<0.05) ^[2]. This indicates that scientific usage and comprehensive nursing support are key to maximizing the advantages of electrosurgical units.

 

Safe use of electrosurgical units relies heavily on standardized nursing coordination. Nursing staff should check equipment status, electrode placement, and power connections before surgery to ensure a safe operating environment; during surgery, they must closely monitor the patient’s vital signs and equipment performance, addressing any anomalies promptly ^[3]. For example, selecting the appropriate output power, preventing patient contact with metal surfaces, and using insulation protection can effectively prevent burns and other accidents, ensuring smooth surgical procedures.

 

 

The SEH80A electrosurgical unit from ShouLiang-med integrates multiple intelligent technologies to further enhance surgical safety and efficiency. The device offers 8 monopolar and 6 bipolar modes to meet various surgical needs; its intelligent tissue-sensing function can adjust output power in real time, reducing smoke and eschar formation; and the return electrode monitoring system ensures patient safety from multiple dimensions. Additionally, the SEH80A supports laparoscopic interfaces, is compatible with smoke evacuators, and integrates into modern operating rooms, making it suitable for a variety of complex surgical scenarios and reflecting the efficiency and flexibility of modern surgical equipment.

 

In summary, electrosurgical units play a crucial role in modern surgery due to their significant intraoperative advantages and integration with proper nursing care. The application of advanced devices like the SEH80A from Shouliang-med has significantly improved surgical precision and safety, effectively promoting minimally invasive surgery and faster patient recovery.

1.What is Platelet?

Platelets, fragments of cytoplasm derived from bone marrow megakaryocytes, play a central role in hemostasis and thrombosis. When blood vessels are injured, platelets adhere, activate, and aggregate to stop bleeding. Abnormal platelet function can lead to bleeding disorders or thrombotic events. With the widespread use of antiplatelet drugs, such as aspirin and clopidogrel, precise assessment of platelet activation function is increasingly important. Poclight’s next-generation Homogeneous CLIA (Chemiluminescence Immunoassay) technology brings a new level of accuracy and speed to platelet function testing.

.

 

2.Platelet Function and Clinical Significance

Platelet-mediated hemostasis involves three key steps:

a. Adhesion

When the endothelium is disrupted, platelets adhere to the vessel wall via von Willebrand Factor (VWF) and collagen. This process is mediated by glycoprotein receptors CD42a/b/d (GPIb-IX-V), a critical step in platelet adhesion.

b. Activation

Platelets are activated through G-protein-coupled receptors binding to ligands such as thrombin, ADP, ATP, and prostanoids. Activated platelets change shape to a dendritic or octopus-like form.

c. Aggregation

Activated platelets are interconnected by fibrinogen and receptors CD41/61 (GPIIb/IIIa). Platelet granules release their contents into the extracellular fluid, among which CD62P (P-selectin) promotes platelet aggregation through platelet–platelet and platelet–fibrin interactions.

 

Platelet function

Hemostasis and thrombosis: The Key Role of Platelets 

Physiological function: The biological behavior and function of platelets are extremely complex. This includes participating in hemostasis and coagulation, maintaining vascular function, regulating inflammation, the body's immune defense, wound healing, tumor growth and metastasis, etc. Therefore, in clinical activities, the monitoring of platelet functionality is receiving increasing attention.

The average lifespan of platelets is 7 to 9 days. Senescent and dead platelets are eventually phagocytosed and processed in the spleen through the bloodstream.

 

Clinical Significance

1. Thrombosis Risk Assessment:  Patients with Hypertension, diabetes,coronary, artery disease,and other cardiovascular condition, as well as those on antiplatelet or anticoagulant therapy.
2. Pre/Postoperative Evaluation: Predicting thrombus formation and guiding prophylactic measures.
3. Platelet Dysfunction Disorders: For example, Glanzmann’s thrombasthenia (CD41/61 deficiency) and Bernard-Soulier syndrome (CD42a/b/d deficiency).
4.  Antiplatelet Therapy Monitoring: Supporting decisions for drugs like clopidogrel, ticagrelor, and prasugrel.

Since the 1950s, the medical field has been dedicated to solving the "century-old problem" of obesity. In 1952, Swedish doctor Henrikson attempted to treat obesity through extensive small bowel resection. By 1966, a doctor in the United States, inspired by the significant weight loss of patients who had undergone total gastrectomy, designed the prototype of the gastric bypass procedure. Since then, weight loss surgery has continually evolved, from open surgery to minimally invasive techniques like sleeve gastrectomy and RYGB gastric bypass, significantly improving safety and effectiveness.

 

There are various types of weight loss and metabolic surgeries, but sleeve gastrectomy has become the most widely used procedure globally due to its simplicity and lower risk of complications. By reducing stomach volume and restricting digestion and absorption, it can achieve long-term stable weight control and also improve obesity-related chronic diseases such as hypertension, diabetes, and sleep apnea. This has led to the shift of weight loss surgery from being merely a weight loss procedure to becoming a standard treatment for metabolic diseases.

 

As the number of patients undergoing these procedures continues to grow, the patient profile has also become clearer. Patients undergoing weight loss surgery typically have high demands for surgical safety and low tolerance for complications. Many guidelines emphasize the proper use of energy-based devices, as the occurrence of complications like gastric leakage is closely related to them. Since the early use of electrosurgical instruments in surgeries, devices that convert electrical energy into heat to achieve hemostasis have gradually replaced traditional cold knife cutting and suturing tools. Current mainstream devices, such as high-frequency electrosurgical knives, ultrasonic knives, and large vessel sealing devices, offer excellent hemostasis, quick cutting, high safety, and effectiveness, making them essential tools in modern surgery.

 

AGISEAL is one of these devices. It is based on the bipolar mode of high-frequency electrosurgical knives, with intelligent updates and iterations to the main unit technology, and has undergone optimization to enlarge the instrument's jaw for sealing and cutting large-diameter blood vessels (below 7mm). This significantly reduces the complex operations and time required by traditional suturing, earning it the title of "advanced bipolar." AGISEAL has shown excellent application in weight loss and metabolic surgeries and has received widespread praise from clinical experts. For example, under precise energy control, it reaches the minimum heat level, ensuring good clinical outcomes while maximizing the avoidance of burns to the gastric wall and the gastric fundus HIS angle, thereby reducing complications such as gastric leakage and gastroesophageal reflux. It meets patients' treatment needs while safeguarding their prognosis and precisely matches the patient profile.

 

Moreover, it combines safe sealing, rapid cutting, non-invasive holding, and fine dissection in one device, which means there is no need to switch surgical instruments or perform suturing and ligation when handling the stomach's greater omentum and short gastric arteries. A single SL0844 can efficiently complete the task, significantly reducing the operational time, helping to save on surgery time, and improving the operational efficiency of medical institutions and clinical departments, ultimately enhancing overall benefits.

 

In conclusion, the AGISEAL series is the undisputed choice to ensure surgical safety and improve efficiency in weight loss surgery.

Hemorrhoids are one of the most common anorectal diseases in clinical practice, with primary symptoms including bleeding, pain, and even prolapse, significantly impacting patients' quality of life. For patients with severe hemorrhoids, surgical excision is an effective treatment. Traditional surgery often employs monopolar electrocautery, which is widely used but associated with issues such as significant thermal damage and slow postoperative recovery. In recent years, with advancements in minimally invasive surgical techniques, bipolar coagulation forceps have been increasingly adopted in hemorrhoidectomy, demonstrating notable advantages.

 

Most medical institutions in China still commonly use monopolar electrocautery for hemorrhoidectomy. This device generates high heat through high-frequency current to achieve tissue cutting and coagulation. Although relatively simple to operate, the current must pass through the patient’s body to form a circuit, resulting in a broader thermal spread that can cause additional damage to healthy tissue around the wound edges. This leads to noticeable postoperative pain, prolonged wound healing, and a relatively higher incidence of complications such as urinary retention and incisional edema ^[1].

 

In contrast, bipolar coagulation forceps confine the current to a minimal area between the two tips, eliminating the need for a circuit through the body. The energy is highly concentrated, with minimal thermal diffusion. While achieving precise hemostasis, it maximally preserves surrounding healthy tissue, making it particularly suitable for the perianal region with dense vascular distribution. Clinical studies have shown that using bipolar coagulation forceps for hemorrhoidectomy significantly reduces operative time, intraoperative blood loss, postoperative pain scores, and promotes wound healing. Additionally, the incidence of complications such as postoperative edema and urinary dysfunction is significantly lower compared to traditional electrocautery ^[2].

 

ShouLiang-med’s independently developed bipolar coagulation forceps integrate high-precision tip design and anti-adhesive coating technology, ensuring concentrated current and minimal thermal damage. They are particularly suitable for delicate procedures such as hemorrhoidectomy. The "coagulation-dissection simultaneously" function enhances anatomical efficiency and operational smoothness, providing a clear surgical field and significantly improving surgical safety and postoperative recovery quality.

 

The application of bipolar coagulation forceps in hemorrhoidectomy offers multiple advantages, including minimal damage, rapid recovery, and fewer complications, aligning with the principles of modern minimally invasive surgery and enhanced recovery after surgery. ShouLiang-med’s bipolar coagulation forceps, with their excellent performance, are a reliable choice in the field of anorectal surgery.

Chronic cervicitis, including cervical erosion, hypertrophy, polyps, etc., are common conditions in women of childbearing age. In some gynecological outpatient departments, the incidence can reach nearly 10%. Traditional treatment methods such as cryotherapy, laser, microwave, and medications have had some efficacy but often fail to achieve satisfactory results and have high recurrence rates. In recent years, the incidence of CIN (Cervical Intraepithelial Neoplasia) has been rising among women of reproductive age, which is a crucial stage in the progression to invasive cervical cancer. Early diagnosis and treatment can significantly reduce the incidence of cervical cancer. Some hospitals have now included cervical carcinoma in situ in the scope of LEEP electrosurgical excision.

 

LEEP electrosurgical excision has shown significant advantages in the treatment of cervical diseases. According to the clinical observation study "Clinical Observation of LEEP Electrosurgical Excision for Cervical Diseases in 276 Cases," published by Wu Shengjun and others in Chinese Journal of Maternal and Child Health Research, this technique uses a high-frequency electrosurgical knife to precisely excise the diseased tissue. The procedure causes minimal discomfort for patients, with only a small number experiencing mild lower abdominal pain or a burning sensation. The average blood loss is only 5-6 mL, and the surgery time is as short as 7.3 minutes, with no need for hospitalization, making it an outpatient procedure. Postoperative recovery is quick, with 96.4% of patients showing normal cervical morphology within 1-2 months, and the overall complication rate is low.

 

Furthermore, the LEEP procedure combines both diagnostic and therapeutic functions. The excised tissue is free of carbonization, making it suitable for pathological examination, which is especially beneficial for early intervention in CIN. Compared to traditional methods such as cryotherapy and laser, LEEP has a lower recurrence rate and can preserve the patient's fertility. It is effective for various lesions such as cervical erosion, polyps, condyloma acuminata, and submucosal fibroids, and is easy to operate with high safety. Although long-term outcomes, such as the risk of cervical canal stenosis, still require more data validation, existing research indicates that its clinical value for widespread use is significant.

 

ShouLiang-med is committed to providing safe and stable high-frequency surgical equipment and a variety of gynecological surgical instruments. Its self-developed High Frequency Generator feature multiple cutting and coagulation modes, which meet the cutting and coagulation needs of gynecological surgeries, further reducing surgery time and blood loss, thereby ensuring patient safety. The company also offers different specifications of LEEP electrodes to meet the needs of various surgical scenarios. The electrodes are made of high-quality tungsten alloy, which further reduces the risks associated with tissue adhesion and carbonization during the procedure. Shouliang Medical's instruments are recognized by clinicians for their excellent materials, good anti-adhesion properties, and precise cutting and coagulation effects. The company hopes to provide safer solutions for global patients and more efficient energy systems for medical institutions in the future.

I. What is OCT? A Core Metaphor

Let’s understand OCT through a vivid analogy:

Imagine a fresh sandwich. A regular camera can only capture its top view (a two-dimensional photo). OCT, however, acts like a precise “optical scalpel.” It can slice the sandwich layer by layer without damage, capturing ultra-high-resolution images of each component (bread, vegetables, meat slices). These cross-sectional images are then reconstructed into a three-dimensional model.

In the eye, this “sandwich” is your retina—the light-sensitive tissue at the back of the eyeball. OCT generates cross-sectional images of the retina’s microscopic structure without any incisions or contact, achieving micrometer-level precision (1 micrometer = 0.001 millimeters)—far finer than a strand of hair!



II. How Does OCT Work?

OCT operates on a principle similar to ultrasound, but instead of sound waves, it uses near-infrared light.

1. Emission: The device emits a safe, low-energy near-infrared light beam toward your eye.
   
2. Reflection: This light passes through the eyeball and reflects back from different layers of the retina. Each tissue layer reflects light signals with distinct intensities and time delays.
   
3. Analysis: The device’s core interferometer precisely measures the differences between these reflected signals and the reference light (“interference” phenomenon).
   
4. Imaging: A computer analyzes and processes the countless captured light signal points, instantly constructing detailed 2D or 3D images.
   
   III. What Can OCT Detect? Which Eye Conditions Does It Diagnose?
   OCT is a powerful tool for examining the macula (the central part of the retina responsible for sharpest vision). With it, doctors can:
   
5. Precisely measure thickness: Determine whether the retina has thickened (edema, hemorrhage) or thinned (atrophy).
   
6. Identify minute lesions: Detect fluid accumulation, abnormal membranes, and microbleeds invisible to the naked eye.
   
7. Monitor disease progression dynamically: Evaluate treatment efficacy and guide subsequent therapeutic decisions.
   
   It is primarily applied in the diagnosis and management of these major blinding eye diseases:
   
8. Age-related macular degeneration (AMD)
   
   Wet AMD: OCT clearly visualizes abnormal subretinal vessels and fluid accumulation, serving as the gold standard for diagnosis and determining the need for intravitreal injections.
   
   Dry AMD: OCT monitors for macular thinning (geographic atrophy) and the deposition of drusen.
   
9. Diabetic Retinopathy & Diabetic Macular Edema (DME)
   
   OCT is the most sensitive tool for detecting DME (intraretinal fluid accumulation), precisely guiding laser or anti-VEGF drug injection treatments while objectively evaluating their efficacy.
   
10. Glaucoma
    
    OCT accurately measures the thickness of the retinal nerve fiber layer (RNFL). Glaucoma causes the RNFL to gradually thin like the growth rings of a tree. OCT can detect these changes early, before visual field defects occur, enabling early diagnosis, timely treatment, and lifelong follow-up for glaucoma.
    
11. Vitreoretinal Interface Diseases
    
    Such as epiretinal membrane (a membrane growing over the retina’s surface, causing distorted vision) and macular hole (a “hole” forming in the center of the macula). OCT clearly displays the morphology and staging of lesions, serving as a key basis for determining surgical necessity.
    
    IV. What is the OCT examination experience like?
    
12. Preparation: Typically requires no special preparation. Sometimes dilating eye drops are administered to enlarge the pupil for clearer imaging, resulting in light sensitivity and blurred near vision for several hours afterward.
    
13. Procedure: Simply rest your chin and forehead on the instrument’s support to keep your head steady. Focus on the fixation point inside the device (possibly a flashing cursor). The device does not touch your eyes.
    
14. Duration: Scanning each eye usually takes only a few minutes.
    
15. Safety: OCT uses near-infrared light. It is radiation-free, non-invasive, and has no known side effects. It is very safe and can be repeated frequently.
    
    V. Cutting-Edge Technology: Enhanced OCT
    OCT technology continues to evolve:
    
16. OCT Angiography (OCTA): This is a revolutionary advancement. Without requiring contrast agent injections, it non-invasively reveals the intricate retinal vascular network, greatly facilitating the diagnosis of vascular diseases.
    
17. Wider, Deeper, Faster: Scanning coverage is broader, penetration is deeper, speed is faster, and image quality is higher.
    

    3. Artificial Intelligence (AI): AI algorithms are being applied to automatically analyze OCT images, assisting physicians in rapid disease screening and diagnosis. This holds immense potential for future application in large-scale health screenings.

Core Connection: Addressing the Most Challenging Clinical Scenarios in Pediatric Emergency Care

Pediatric emergency settings represent one of the most valuable applications for venous imaging devices. This connection is primarily manifested in addressing the following core challenges:

1. Patient Specificity: Difficulties in Establishing Venous Access

Physiological Factors: Infants and children possess inherently small, fragile blood vessels and relatively thick subcutaneous fat layers, making vessels invisible to the naked eye and difficult to palpate.

Emotional Factors: Young patients often experience fear, crying, and non-compliance, causing vasoconstriction and further complicating puncture attempts.

Dehydration/Critical Illness: In emergency settings, dehydrated, shock-affected, or hypotensive children exhibit collapsed vessels, making traditional localization nearly impossible.

2. Environmental Specificity: High Pressure and Urgency

Time Pressure: In critical situations (e.g., status epilepticus, severe dehydration, sepsis), rapidly establishing an IV line for medication administration or fluid infusion is vital for saving lives. Each failed attempt delays treatment.

Compounding Stress: A child's distress and parental anxiety create immense psychological pressure on healthcare providers, potentially leading to technical errors and creating a vicious cycle: “The more unsuccessful attempts, the greater the tension; the greater the tension, the fewer successful attempts.”

How does the new vein imaging device transform pediatric emergency care?

This innovative technology uses near-infrared light to project real-time images of subcutaneous veins directly onto the skin surface, clearly revealing vessel location, trajectory, and branching patterns.

Its specific value in pediatric emergencies includes:

1. Significantly increases first-attempt success rates

This is the most critical metric. Studies show vein imaging devices can boost first-attempt success rates in pediatric patients by 20% to 50% or more.

Significance: Reduces patient distress, shortens access establishment time, and secures a valuable window for critical interventions.

2. Reduces overall puncture attempts

Average attempts decrease from 3-4 to 1-2, or even one successful attempt.

Significance:

- Minimizes trauma for children: Prevents them from becoming “needle pads,” reducing physical and psychological harm.

- Alleviates parental anxiety: Significantly boosts parents' trust in the medical team.

- Protects healthcare providers: Lowers work frustration and enhances job satisfaction.

3. Provides solutions for “difficult vein” patients

For obese children, those with darker skin tones, severe dehydration, or multiple chemotherapy treatments, vein imaging devices are nearly the only non-invasive, rapid tool for locating veins.

4. Optimizing Workflow and Enhancing Emergency Department Efficiency

Reduces the need to call senior nurses or anesthesiologists for central venous catheterization due to repeated puncture attempts.

Enables healthcare providers to treat more patients faster, alleviating emergency department congestion.

5. As a Communication and Reassurance Tool

For patients: Project images onto their hands or toys, turning the process into a “game” to distract and reduce fear.

For parents: Visually demonstrate vein locations, helping them understand the procedure's difficulty and necessity. This transforms them from bystanders into “allies,” strengthening communication and trust.
