In the field of gynecological clinical practice, surgical treatment of diseases such as pelvic organ prolapse, uterine lesions, and urinary fistulas has always faced challenges including limited surgical field exposure, narrow operating space, and high reliance on manpower. Traditional retractors often struggle to accurately adapt to the complex anatomical structure of the pelvic cavity and require continuous holding by assistants, which not only affects surgical efficiency but also may increase surgical risks due to unstable tension. The disposable surgical self-retaining retractors from Chamfond Biotech, with their innovative design, multi-model adaptability, and excellent clinical performance, have become an ideal auxiliary tool for various gynecological surgeries, providing strong support for precision medicine.
Core Product Advantages: Exclusive Design for Gynecological Surgeries
Composed of a retractor ring and elastic retractor hooks, the disposable surgical self-retaining retractors perfectly match the special needs of gynecological surgeries through targeted technological innovations:
- Safety Guaranteed by High-Quality Materials: The retractor ring is made of high-strength biocompatible engineering plastic, and the elastic retractor hooks consist of stainless steel metal hooks combined with silicone elastic strips. Non-toxic and non-irritating, they meet the requirements of human tissue compatibility, avoiding the risk of intraoperative allergies or tissue damage. The disposable design eliminates cross-infection.
- Precise Adaptability with Multiple Models: Multiple exclusive retractor ring models are launched for gynecological surgical scenarios, providing precise support from routine surgeries to those for patients with special body types, and from simple operations to complex reconstructive surgeries. Meanwhile, 8 types of elastic retractor hooks are available, including single-pointed hooks, double-blunt hooks, and three-pronged rake hooks, which can be flexibly selected according to tissue type and exposure needs.
- 360-Degree Surgical Field Exposure: The retractor ring supports 360-degree omni-directional adjustment, enabling fixation and exposure of the surgical field from any angle. Combined with the hierarchical exposure function, retraction points can be adjusted in an orderly manner to gradually present the anatomical structure of the uterus, ovaries, fallopian tubes, and surrounding tissues in the pelvic cavity, solving the problem of blind spots with traditional instruments.
- Stability and Anti-Slip for Reliability: The limit structure design effectively prevents the retractor hooks from slipping during surgery, ensuring stable retraction of the surgical site, avoiding surgical interruptions or tissue damage caused by instrument displacement, and providing continuous and reliable visual support for complex operations.
- Manpower Saving and Efficiency Improvement: The adaptive retraction system does not require continuous holding by assistants, allowing the medical team to focus on surgical operations. It not only reduces labor costs but also minimizes tension fluctuations caused by manual holding, improving the precision and safety of surgical operations.
- Space Optimization for Pelvic Cavity Adaptation: The compact structural design significantly reduces the space occupied in the surgical area, making it particularly suitable for the anatomical environment of the narrow pelvic cavity and reserving sufficient space for instrument operation to facilitate minimally invasive surgeries.

Clinical Application Cases: Covering Diverse Gynecological Surgical Scenarios
Case 1: Pelvic Floor Reconstruction for Pelvic Organ Prolapse (POP)
A 62-year-old female patient was diagnosed with grade III uterine prolapse combined with anterior and posterior vaginal wall prolapse. Due to a narrow pelvic cavity and obesity, traditional surgical field exposure was difficult. The physician selected the C17 retractor (22.0*11.3cm) with double-blunt elastic retractor hooks. During the surgery, the retractor ring was accurately fixed in the optimal position through 360-degree omni-directional adjustment. The hierarchical exposure technology gradually expanded the anterior and posterior vaginal walls and surrounding uterine tissues, clearly presenting the area of pelvic floor fascia defect. The limit anti-slip design ensured the retractor hooks remained stable throughout the procedure without the need for assistant holding, allowing the physician to focus on fascia repair and suspension. The surgery was successfully completed in 75 minutes, 30 minutes shorter than the traditional approach, with intraoperative blood loss reduced by 40%. The patient was able to get out of bed on the 3rd day after surgery, and no recurrence of prolapse was observed during the 6-month follow-up.
Case 2: Repair of Complex Vesicovaginal Fistula (VVF)
A 48-year-old female patient developed a complex vesicovaginal fistula (fistula diameter 1.8cm, located below the trigone of the bladder) after hysterectomy. The physician selected the C16 retractor (32.5*18.3cm) with three-pronged rake hooks for transvaginal repair. The omni-directional exposure function of the retractor provided clear visualization of the fistula and surrounding tissues. After hierarchical adjustment of retraction points, the physician accurately separated the adherent tissues between the bladder and vagina, completely resected the fistula, and performed layered suturing. The space-optimized design of the instrument provided sufficient room for suturing operations, and the self-retaining feature avoided tissue displacement that might occur with manual holding, significantly improving the surgical success rate. The patient had the urinary catheter removed on the 10th day after surgery without urinary leakage, and the fistula was completely healed during the 1-month follow-up.
Case 3: Transvaginal Hysterectomy (VH)
A 55-year-old female patient required total hysterectomy due to multiple uterine fibroids (maximum diameter 8cm) and chose the transvaginal surgical approach based on her wishes. The physician selected the C12 retractor (16.6*16.6cm) with single-pointed hooks. During the surgery, the retractor quickly exposed the vaginal fornix and parauterine tissues, and the 360-degree adjustment function clearly displayed important structures such as uterine blood vessels and ligaments. Without the need for assistant retraction, the surgical team collaborated efficiently to successfully complete the separation, ligation, and resection of the uterus and appendages. The surgery lasted 60 minutes, 25 minutes shorter than the traditional transvaginal surgery, with intraoperative blood loss of only 80ml. The patient was discharged from the hospital 4 days after surgery with no abdominal scars and resumed normal life 1 month postoperatively.
Case 4: Radical Surgery for Deep Infiltrating Endometriosis (DIE)
A 38-year-old female patient was diagnosed with stage IV endometriosis with lesions infiltrating the rectovaginal septum (depth ≥6mm), requiring multidisciplinary collaborative radical surgery. The physician selected the C18 retractor (29.1*18.3cm) with four-pronged rake hooks. The hierarchical exposure function gradually revealed the extensively adherent lesion tissues in the pelvic cavity, and the 360-degree omni-directional adjustment allowed clear identification of lesions on the ovaries, uterosacral ligaments, and rectal wall. The stable fixation of the retractor enabled gynecologists and colorectal surgeons to operate collaboratively to accurately resect ectopic lesions and separate adhesions. The surgery lasted 120 minutes, 40 minutes shorter than the traditional approach, with no damage to the rectum or ureters during the operation. The patient’s dysmenorrhea symptoms were completely relieved after surgery, and no recurrence was observed during the 1-year follow-up.
Case 5: Repair of Rectovaginal Fistula (RVF)
A 32-year-old female patient developed a low rectovaginal fistula (fistula diameter 1.2cm) due to perineal laceration during childbirth, requiring transvaginal repair. The physician selected the C15 retractor (25.3*11.3cm) with double-pronged rake hooks. With the hierarchical exposure function of the retractor, the location of the fistula and the surrounding pelvic floor muscle structure were clearly presented. The self-retaining design avoided fluctuations in intraoperative retraction force, allowing the physician to accurately resect the fistula and perform layered suturing of the anterior rectal wall and posterior vaginal wall. The surgery lasted 45 minutes, and the patient recovered well with no abnormal defecation, restoring normal physiological function 2 months after surgery.
