Summary

This clinical trial is a prospective, multi-center, single-blind, parallel, randomized controlled superiority clinical trial. The trial will be carried out in 5 centers, involving 120 subjects as estimated who will be divided into the test group or control group randomly on an equal basis (each group includes 60 subjects).

This trial will be carried out in 4 stages, including the screening period, random grouping, operation date and follow-up period. In the screening period, the informed consent forms are collected and candidates are screened; after screening, the accepted subjects will be randomly divided into the control group or test group; on the operation date, the operation is carried out using the device tested; safety follow-up visit is carried out during the follow-up period.

  • Lower Abdominal Surgery
  • Pelvic Surgery

Interventions

DEVICE

LED light source system for endoscope

The prospective, multi-center, single-blind, parallel, randomized controlled superiority trial design is adopted to evaluate the safety and effectiveness of the LED light source system for endoscope during ureter transillumination. The trial will be carried out in 5 centers, with the competitive grouping mode adopted. This trial will be carried out in the General Surgery Department and the Gynecology Department. Totally 120 subjects with rectal cancer, endometriosis, cervical cancer, adenomyosis and pelvic adhesion requiring operation (60 subjects for each of the test group and control group) are involved. The test group use LED light source system for endoscope.
