From July 29 to 30, the Yuhang Campus of Women's Hospital, Zhejiang University School of Medicine, utilizing the Edge® Single-Port Laparoscopic Surgical Robot, completed four consecutive surgeries on the first day and three on the second within two days, setting a new record for single-day and consecutive surgeries at the hospital since the completion of the first installation at a national obstetrics and gynecology specialized hospital on May 20. The procedures broadly covered early radical surgeries for gynecological malignancies and common gynecological diseases, fully demonstrating the stability and reliability of the Edge Single-Port Robotic System in high-frequency, multi-procedure consecutive surgery scenarios, marking that the application of single-port robotics at Women's Hospital, Zhejiang University School of Medicine has entered a new phase of normalized and scaled development.

Small Umbilical Incision Brings a New Era of Postoperative "Scarless" Recovery

For gynecological surgery patients, the pursuit of treatment outcomes has long surpassed "safer and less invasive"—beyond precise lesion resection, the protection of fertility and ovarian function, along with the desire for better cosmetic outcomes, has become particularly prominent. How to maximize functional preservation and aesthetic outcomes while improving treatment efficacy is a critical challenge in gynecological minimally invasive techniques—and a unique value proposition of single-port robotic surgery.

Over the two-day high-density surgical schedule, experts at Women's Hospital, Zhejiang University School of Medicine, including Director Shen Yuanming, Director Huang Xiufeng, Director Wang Yinfeng, and Director Zhu Changkun, successively performed all seven surgeries using the Edge® Single-Port Laparoscopic Robot. The procedures broadly covered common gynecological conditions such as ovarian cysts, ectopic pregnancy, and uterine fibroid removal, pelvic floor reconstruction for uterine prolapse, and early radical surgeries for gynecological malignancies including endometrial cancer, ovarian cancer, and cervical cancer.

All surgeries were performed through a transumbilical single-incision approach, completing the entire operation efficiently through a tiny incision of approximately 2cm. The incision was perfectly concealed within the natural folds of the navel, ensuring complete lesion resection and surgical safety while minimizing the impact on patients' abdominal appearance—truly achieving the minimally invasive aesthetic goal of "scarless postoperative recovery without compromising beauty."

The "Flexible Arm" Enables Continuous Multi-Region Operation in the Same Position

In one case, during an ovarian cancer radical surgery performed by Director Shen Yuanming from the Gynecologic Oncology Department, the Edge Single-Port Robot's "Flexible Arm" technology demonstrated significant advantages in intraoperative planning and seamless switching of surgical target visual fields, enabling continuous multi-region operation in the same patient position while ensuring surgical quality and improving overall procedural efficiency.

Traditional laparoscopic surgery often requires repositioning the patient or rearranging the surgical field when addressing both pelvic and upper abdominal pathologies—a cumbersome and time-consuming process. In this procedure, leveraging the Edge Single-Port Robot's flexible instrument range of motion and excellent surgical visualization, Director Shen completed total hysterectomy and bilateral adnexectomy, then proceeded directly to omentectomy without changing the patient's position, achieving continuous, smooth operation from the pelvis to the upper abdomen. The surgery took only 90 minutes with blood loss of less than 20ml, reducing intraoperative transition time while enhancing the overall efficiency of minimally invasive surgery—delivering a more precise and safe minimally invasive treatment experience for patients with complex gynecological malignancies.

A New Breakthrough in "Non-Invasive" Surgery, Where Health and Beauty Coexist

Within two days, Director Wang Yinfeng from the Yuhang Campus Gynecology Department successfully completed three surgeries using the single-port robot: transvaginal combined single-port iliopectineal ligament suspension, ovarian cystectomy, and total hysterectomy—covering three major areas: pelvic floor reconstruction, benign ovarian tumor resection, and hysterectomy. All three procedures were performed with minimal blood loss.

Notably, two months earlier, the team had successfully performed the first transvaginal single-port robot-assisted pelvic floor reconstruction surgery at Women's Hospital, Zhejiang University School of Medicine, utilizing natural orifices to achieve non-invasive surgery.

The patient presented with multiple high-risk factors including severe pelvic organ prolapse, multiple uterine fibroids, obesity, and a history of multiple abdominal and pelvic surgeries. The team customized an individualized surgical plan: transvaginal single-port robot-assisted total hysterectomy and bilateral adnexectomy, simultaneously performing sacral ligament high uterosacral suspension, cystocele repair, anterior and posterior vaginal wall repair, and perineal old laceration plasty—a one-stop pelvic floor reconstruction. The entire procedure was performed through the natural orifice (vagina), requiring no abdominal incisions.

This case vividly demonstrates the unique value of single-port robotic surgery in gynecology: minimizing trauma to the extreme, even achieving non-invasiveness, perfectly realizing the vision of "preserving both health and beauty."

Nearly 30 Cases in a Single Month, Edge Single-Port Robotics Moving Toward Daily Clinical Application

With the continuous advancement of minimally invasive techniques, an increasing number of patients—especially women—have raised higher expectations for cosmetic outcomes. Compared with traditional minimally invasive surgery, single-port robotic minimally invasive technology, which perfectly combines the "scarless nature of single-port surgery" with the "precision of robotics," demonstrates unparalleled core advantages, particularly in the field of gynecology, opening new possibilities for complex and reconstructive procedures.

As the first domestically approved single-arm single-port laparoscopic surgical robot, the Edge® Single-Port Robot provides a precise answer to the clinical demand for "curing the disease, minimizing scarring, and accelerating recovery": it delivers a magnified 10x high-definition 3D visualization, making even the finest blood vessels, nerves, and lymphatic vessels clearly visible to the surgeon, minimizing collateral damage; its articulating instruments offer 7 degrees of freedom with 540-degree rotation and automatic tremor filtration—effectively eliminating the "chopstick effect" commonly seen in traditional single-port laparoscopy, where instruments interfere with each other in confined spaces. For fine operations such as suturing, knotting, and lymph node dissection deep in the pelvic cavity, the system enables smooth, precise movements. This not only enhances surgical precision and safety but also provides better technical support for critical patient concerns, including ovarian function preservation and fertility protection.

At Women's Hospital, Zhejiang University School of Medicine, these technical advantages have been fully realized. Leveraging the hospital's long-standing expertise in gynecological minimally invasive surgery, along with the team's extensive experience in multi-port robotics, transvaginal surgery, and single-port laparoscopy, the integration of the Edge Single-Port Robot with gynecological specialty strengths has significantly reduced surgical trauma and intraoperative bleeding. Patients experience faster postoperative recovery and substantially shortened hospital stays—truly benefiting from the dual dividends of cutting-edge medical technology: both safe and effective treatment, alongside enhanced quality of life and comprehensive physical and mental rehabilitation.

Since its first commercial installation at Women's Hospital, Zhejiang University School of Medicine on May 20—the first of its kind in a national obstetrics and gynecology specialized hospital—an increasing number of patients from across Zhejiang Province and beyond have sought treatment at the hospital. Surgical volume has grown rapidly, with nearly 30 cases performed in July alone. The application of single-port robotics has entered a new phase of normalized and scaled development.

From "single cases" to "high-density consecutive surgeries with 7 cases in 2 days"—Edge Medical is working hand in hand with Women's Hospital, Zhejiang University School of Medicine and other leading clinical partners to transform single-port robotic surgery from technical validation to daily clinical practice, bringing the benefits of precision minimally invasive treatment to more patients through high-end medical equipment.
