• High-Frequency Electrosurgical Unit Demonstrates Significant Advantages in Treating Hemorrhoids

  Aug 15, 2025

  Hemorrhoids, also known as anal fistula disease, have an incidence rate of 40%-50%. There's a  folk saying that "nine out of ten people develop hemorrhoids." Modern medical research has found that hemorrhoids are a physiological change, and humans naturally have a risk of developing hemorrhoids. Hemorrhoids can cause significant harm, with severe pain being the primary symptom during an episode. META analysis indicates that hemorrhoids are an important risk factor for colorectal cancer and are closely related to constipation, among other conditions. They negatively impact patients' daily lives and work, severely impairing their quality of life.   Hemorrhoid treatment can be divided into surgical and conservative therapies. Among them, surgical treatment has been increasingly popular due to its continuous improvement in technology and significantly reduced trauma. External excision and internal ligation, automatic hemorrhoid ligation, and circular mucosal resection and stapling of the hemorrhoids have gradually become widespread. Minimally invasive surgery has been proven effective, but its indications are limited. High-frequency electrosurgical unit combines the advantages of traditional ligation and circular ligation, using the electrosurgical unit to remove hemorrhoidal tissue, achieving good removal results.[1]   According to research data from the Department of Anorectal Surgery at Wuhan Fifth Hospital involving 174 patients, the incidence of complications in the observation group treated with high-frequency electrosurgical unit surgery was 26.4%, significantly lower than the 52.9% in the control group treated with traditional ligation surgery. particularly in key indicators such as anal-rectal stenosis (13.8% vs. 23.0%) and postoperative edema (8.0% vs. 14.9%), where the differences were statistically significant. This technique combines electrocoagulation hemostasis with ligation technology to achieve simultaneous hemostasis during surgery, reduce nerve ending exposure, and lower the pain score to 2.5 ± 1.4 points within three days postoperatively (3.9 ± 1.2 points in the traditional group). The pain score during dressing changes was controlled at 5.6 ± 1.3 points (7.1 ± 1.6 points in the traditional group). Patients recovered faster postoperatively, with time to ambulation shortened to 7.3 ± 1.3 hours and time to first bowel movement reduced to 4.3 ± 1.1 minutes. At the 6-month follow-up, the incidence of defecation difficulties (3.4%) and symptomatic recurrence rate (5.7%) in the observation group were significantly lower than those in the traditional surgery group (16.1%). The precise resection characteristics of the observation group preserved more normal anal cushion tissue, effectively reducing the risk of anal functional damage.   In summary, high-frequency electrosurgery unit enables simultaneous resection and hemostasis through minimally invasive procedures, demonstrating significant clinical advantages—particularly for treating multiple mixed hemorrhoids.     ShouLiang-med's independently developed high-frequency electrosurgical unit offers multiple cutting and coagulation modes, meeting all functional requirements for hemorrhoid surgery while further reducing patient injury and complications. Additionally, the monopolar electrodes and electrical pencils provided by ShouLiang-med are made from high-quality anti-adhesive materials, further optimizing surgical efficiency.     [1] Dai Luo, Hu Qi.

• Bipolar Forceps: An Effective Alternative to Ultrasonic Scalpel in Open Thyroidectomy

  Jul 10, 2025

  With the increasing prevalence of early thyroid disease screening, the diagnosis and surgical rates of thyroid conditions are on the rise. For malignant tumors and large benign nodules that impair swallowing or breathing, unilateral or bilateral lobectomy remains the standard treatment [1]. High-quality surgical instruments not only improve efficiency but also reduce complications.   In most Chinese hospitals, ultrasonic scalpels are commonly used in thyroid surgery. These devices utilize high-frequency vibrations to break protein bonds, enabling simultaneous tissue dissection and vessel sealing. Ultrasonic scalpels are flexible and can replace multiple traditional instruments—including electrocautery, scissors, vascular clamps, ligatures, and sutures—thereby shortening operative time and minimizing blood loss. Furthermore, they do not cause neuromuscular electrical stimulation. However, potential risks exist: the relatively bulky “scissor-style” blade of the ultrasonic scalpel may conduct excessive heat near delicate structures, such as the recurrent laryngeal nerve, increasing the risk of thermal injury and even permanent paralysis [2].   Bipolar coagulation systems, originally used in neurosurgery, have shown excellent hemostatic precision in small vessels and are increasingly favored by thyroid surgeons [3]. ShouLiang-med’s bipolar forceps feature mirror-polished tips for superior conductivity, thermal efficiency, and anti-stick performance. Tip widths range from 0.25 mm to 2 mm, making them suitable for a wide range of procedures. In thyroid surgery, they allow for fine dissection near the recurrent laryngeal nerve and precise control of minor bleeding around nerve structures, with minimal thermal spread to adjacent tissues.   Preserving the parathyroid glands and their blood supply is another key challenge. Studies have shown a significantly lower incidence of postoperative hypocalcemia in patients treated with bipolar forceps compared to those treated with ultrasonic scalpels [4], likely due to the reduced collateral thermal damage and better vascular control. Moreover, postoperative drainage volumes were also lower in the bipolar group, possibly due to: (1) more precise coagulation of microvasculature, and (2) lower thermal tissue exudation compared to ultrasonic devices.   In conclusion, bipolar forceps offer a cost-effective solution with fine tips and limited thermal spread, significantly reducing the risk of injury to the recurrent laryngeal nerve and parathyroid glands. They present a viable alternative to ultrasonic scalpels in open thyroidectomy [4].     References [1] Thompson NW, Olsen WR, Hoffman GL.
