Disposable Intestinal Isolation and Protection Device for Patients With Rectal and Lower Sigmoid Colon Tumors Undergoing Laparoscopic AR/LAR Surgery

2026년 9월 16일 업데이트: Zhongtao Zhang, Beijing Friendship Hospital

A Randomized, Controlled, Open Multicenter Clinical Study on the Efficacy and Safety of a Disposable Intestinal Isolation Protective Device in Patients With Rectal and Lower Sigmoid Colon Tumors Undergoing Laparoscopic AR/LAR Surgery

The small intestine is the main organ in the abdominal cavity, approximately 4 to 5 meters in length, occupying most of the middle and lower abdomen. Due to the long mesentery of the small intestine, it is in a free state and has a high degree of mobility. When performing abdominal surgery, especially lower abdominal surgery, the freedom and slippability of the small intestine often affect the exposure of the surgical site and the operating field of vision. Lower abdominal surgery generally includes colorectal surgery, gynecological surgery, urological surgery, etc. At present, in clinical practice, open surgeries, including minimally invasive laparoscopic manual surgeries, mainly involve significantly adjusting the patient's position to slide the small intestine into the surgical field, or simply surrounding and covering the small intestine with gauze pads and assisting in pulling with the help of assistants. However, the results are not satisfactory, especially for obese patients.

In the current clinical practice of performing middle and lower abdominal surgeries, especially laparoscopic surgeries, a device superior to gauze isolation pads is needed. It can separate the small intestine from the surgical site to expose the surgical area, facilitating doctors to perform manual operations calmly and reducing the operation time and complications. Avoid the special position with the head low and the feet high, which may increase the risk of restricted cardiac and respiratory functions in patients and reduce the impact on surgical anesthesia.

To collect more data on the efficacy and safety of this product for abdominal surgery, it is planned to conduct this post-market clinical study. This clinical study will adhere to the Good Clinical Practice for Medical Devices and relevant laws and regulations, and strictly implement the clinical research protocol.

기간
Evaluation of equipment usage
기간: From the time of enrollment until the end of the 3-month treatment period.
On the day of the surgery (within 24 hours), the researchers evaluated the ease of use of the product during open surgery and laparoscopic surgery, whether there was accidental injury to surrounding organs, whether the surgical field was satisfactory, and whether multiple isolations were required. Use a 5-point scale (0 for light, 5 for heavy, in ascending order).
From the time of enrollment until the end of the 3-month treatment period.
Surgical Position Record
기간: From the time of enrollment until the end of the 3-month treatment period.
On the day of surgery (within 24h), the researcher adjusted the body position according to the intraoperative requirements, which was supine, within 15° (0-15° including 15°), 15-30 ° (15°-30° including 30°), and more than 30° (greater than 30°).
From the time of enrollment until the end of the 3-month treatment period.
First exhaust time
기간: From the time of enrollment until the end of the 3-month treatment period.
Starting from the day of the surgery, record the duration (eg. 12h-24 m, HH-MM) of the first time the patient passed gas after the surgery.
From the time of enrollment until the end of the 3-month treatment period.
