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.

Uterine fibroids are benign tumors arising from the proliferation of smooth muscle cells in the uterus, affecting approximately 30% of women of reproductive age, with a malignancy rate of 0.4%–0.8%. Surgery remains the primary treatment, and advances in medical technology have enabled laparoscopic techniques to make significant strides in gynecology. Laparoscopic myomectomy is widely adopted due to its minimally invasive nature, reduced pain, and overall safety. However, intraoperative hemostasis of the fibroid bed remains a clinical challenge.

 

In a study published in Practical Journal of Integrated Chinese and Western Medicine, Li Kehong et al. compared the clinical performance of ultrasonic scalpels, monopolar electrosurgical devices, and cold knives in 92 laparoscopic myomectomy cases. Patients were divided into three groups: ultrasonic scalpel (32 cases), monopolar electrosurgery (32 cases), and cold knife (28 cases).

 

Results showed that both the ultrasonic scalpel and monopolar electrosurgery groups outperformed the cold knife group in terms of operative time, intraoperative blood loss, and uterine suturing time. Specifically, the monopolar group achieved a significantly shorter operative time (64.6±10.3 minutes vs. 81.7±11.6 minutes), reduced blood loss (103.3±11.5 ml vs.146.6±13.2 ml), and faster suturing (19.4±4.1 minutes vs. 24.3±3.2 minutes). Postoperative recovery was also improved, with earlier mobilization (12.4±4.2 hours) and shorter hospital stays (3.7±0.6 days). The study highlighted the strong performance of monopolar electrosurgery in enhancing surgical efficiency and postoperative recovery, noting its ease of use and cost-effectiveness as key advantages in laparoscopic myomectomy.

Pregnancy-associated breast cancer (PABC) refers to breast cancer diagnosed during pregnancy or within one year postpartum, with an incidence of (2.4 to 7.3) cases per 100,000 pregnancies. Regarding the treatment of PABC, the international medical community currently believes that while continuing the pregnancy, necessary surgery and chemotherapy should be performed for the breast cancer, but the patient's and foetus's vital signs and changes in condition must be closely monitored throughout the entire process.

 

Chen Peng et al. mentioned in their paper "Application of electrosurgical equipment in operative treatment of PABC and the discuss of its safety guarantee" that a case of a 27-year-old PABC patient admitted to the Central Hospital of Cangzhou City, Hebei Province. The patient presented with a right breast mass discovered at 33 weeks of gestation, 10 days prior to admission. Outpatient bilateral breast ultrasound revealed a hypoechoic mass in the right breast (BI-RADS 4b category) and enlarged right axillary lymph nodes, with an initial diagnosis of right breast cancer. Electrosurgical equipment was used to perform a modified radical mastectomy. Prior to the procedure, the patient and her family were consulted multiple times, and they strongly expressed their desire to preserve the pregnancy. A multidisciplinary consultation involving the breast surgery, obstetrics, and anaesthesiology departments found no significant contraindications for surgery. Therefore, the procedure was conducted under general anaesthesia with continuous fetal heart monitoring.

 

In conventional surgery, procedures such as free flap dissection, total mastectomy, and axillary lymph node dissection all utilise monopolar high-frequency electrosurgical instruments. The principle of operation of monopolar high-frequency electrosurgical instruments is as follows: the high-frequency current from the electrosurgical instrument is applied to the human body via the electrosurgical pencil, producing cutting or coagulation effects. The current is conducted through the human body and returns to the electrosurgical equipment via the return negative electrode. To minimise the impact of using the high-frequency electrosurgical knife on the patient, a low-frequency cutting mode at 35 kHz and a low-frequency electrocoagulation mode at 30 kHz are employed. At the same frequency, these modes cause the least damage to both the mother and the foetus. 

 

Conventional modified radical mastectomy (MRM) for breast cancer typically does not involve the use of bipolar forceps. However, due to the specific condition of this patient, bipolar coagulation was employed during flap dissection and hemostasis, as well as in the handling of small vessels and lymphatics, effectively reducing the use of monopolar electrosurgery. The technique demonstrated reliable hemostasis, minimizing the need for ligatures.

 

Based on intraoperative data, standard MRM performed with minimal use of electrosurgical devices generally requires around 95 minutes with an average blood loss of approximately 50 ml. In contrast, the PABC (Pregnancy-Associated Breast Cancer) patient in this study underwent surgery with the same approach and extent of dissection, yet the operative time was reduced to 80 minutes and blood loss to about 30 ml. The appropriate use of electrosurgical tools clearly contributed to this improvement.

 

Follow-up at 10 days postoperatively showed good flap perfusion at the incision site, with normal color and volume of axillary drainage and no significant surgical complications.

 

ShouLiang-med’s high-frequency surgical system offers multiple cutting and coagulation modes, meeting the low-frequency energy needs required for MRM in PABC patients. This supports shorter operative times and reduced blood loss, contributing to maternal-fetal safety. In addition, ShouLiang-med’s monopolar and bipolar instruments are made with high-quality non-stick materials, further minimizing the risk of tissue adhesion during surgery.

With the rising rate of HPV infection, the prevalence of cervical intraepithelial neoplasia (CIN), a precancerous lesion of cervical cancer, is showing a younger trend, with more and more women of reproductive age being diagnosed. About 60% of low-grade lesions may resolve spontaneously, while high-grade lesions have cancerous potential and require further diagnosis and treatment.

 

Treatment options for CIN include conservative and surgical treatments, with surgery being the only effective treatment for persistent CIN. Currently, cold-knife conization (CKC) and loop electrosurgical excision procedure (LEEP) are the most widely used surgical methods for cervical conization.

  

The CKC procedure use a traditional surgical scalpel to cut tissue. It can remove a sufficiently large and intact cervix at one time for histopathological testing, with clear margins of the resected specimen, without affecting the diagnosis of histopathology. However, intraoperative bleeding is not easy to control, and excessive intraoperative and postoperative bleeding is likely to occur. Moreover, there is a higher incidence of complications affecting subsequent pregnancies, such as cervical adhesion and cervical insufficiency. 

 

LEEP employs a loop-shaped metal wire (electrode loop) to conduct high-frequency alternating current.It uses the drying and dehydrating effect and arc cutting effect unique to high-frequency electric current to cut the tissues contacted by the loop. The operation is relatively simple and there is a low incidence of complications such as cervical adhesions and cervical insufficiency that may affect subsequent pregnancies. However, the limited depth of cut of the LEEP procedure can lead to a positive histopathological diagnosis of the margins of the resected specimen, forcing the patient to undergo a second operation.

 

To overcome the limitations of traditional cervical conization techniques, the research team at Guangzhou Women and Children's Medical Center innovatively adopted a high-frequency electrosurgical knife equipped with a needle-type electrode for the procedure. This approach combines the broad excision range and effective intraoperative hemostasis of conventional high-frequency electrosurgery with the unique advantages of the needle-shaped electrode—namely, a smaller cutting surface and reduced thermal damage to the excision margins, thereby minimizing the impact on postoperative pathological results.

 

Clinical data: Among 60 patients, the postoperative histopathological diagnosis of the excised cone tissue was consistent with preoperative colposcopic biopsy results in 41 cases, yielding a concordance rate of 68.3%. Additionally, in 15 patients, the postoperative pathology grade was lower, and in 4 patients, higher, than the preoperative biopsy grade. Importantly, all excision margins were negative, with clear edges and no carbonization from electrocoagulation observed.

 

Conclusion: The use of a needle-type high-frequency electrode in cervical conization ensures adequate excision range and hemostasis without compromising margin pathology. Furthermore, the postoperative incidence of pregnancy-related complications such as cervical insufficiency, premature rupture of membranes (PROM), and preterm birth remains low.

 

ShouLiang-med is committed to offering a diverse range of high-frequency surgical instruments, including various needle-type electrodes. These instruments are clinically recognized for their premium materials, anti-adhesion properties, and precise cutting and coagulation performance. Looking ahead, ShouLiang-med aims to empower healthcare providers worldwide with more efficient surgical solutions and help build a safer treatment environment for patients globally.
