Outcomes

Primary Outcome Measures

surgical success rate
The surgical success rate is defined as the proportion of successfully operative subjects in the experimental group or the control group.

Secondary Outcome Measures

The breakage rate of gallbladder
The breakage rate of gallbladder is defined as the proportion of the subjects in the experimental group or the control group with specimen breakage.
Comprehensive Complication Index (CCI)
CCI is calculated using online tools provided by http://cci.assessurgery.com. Based on the Clavien-Dindo complications grade system (appendix.1), all complications and adverse events after surgical intervention are taken into consideration. The overall incidence is measured on a scale ranging from 0 (no complication) to 100 (death).
Operative time
The length of time from the beginning of the operation after the robot installation to the end of the suture of the incision.
Intraoperative bleeding
The total bleeding volume from the beginning of the operation to the end of the suture of the incision. It can be calculated by measuring the blood volume in the vacuum suction device and weighing the gauze after using them to wipe the bleeding.
Postoperative pain
Postoperative pain is assessed by visual analogue scale (VAS) 24-26 hours after the operation, ranging from 0 (no pain) to 10 (maximum pain).
Time to first flatus
The time from the end of the operation to the subject's first flatus after surgery.
Surgeon's satisfaction
After the operation, surgeons fill a questionnaire to score the flexibility, intuition and stability of the products, as well as their sense of delay and fatigue when using the products. Each question in the score ranges from 1 to 5 points and the total score is 100.
Installation time
The time from the power-on of the products to the end of the connection between trocars and the operative arms.
Hospital stay
The total hospital days of subjects from admission to discharge.

5. Study Description

Brief Summary
This is a prospective, multi-center, randomized, single-blind, parallel-controlled clinical trial to evaluate the safety and efficacy of the Chinese domestic endoscopic instrument control system in clinical treatment.
Detailed Description
To evaluate the safety and efficacy of the Chinese domestic endoscopic instrument control system in clinical treatment.This clinical trial is a prospective, multi-center, randomized, single-blind, parallel-controlled study. The system used in the experimental group is the endoscopic instrument control system developed by WEGO Surgical Robot Co., Ltd., and the system used in the control group is the da Vinci endoscopic instrument control system developed by Intuitive Surgical. Before patients are enrolled in this clinical study, the researchers will do a detailed screening of the subjects based on the inclusion criteria and the exclusion criteria to determine if the patients are appropriate for the clinical study. Patients who meet the conditions of the study will be required to sign an informed consent form. Then they will be randomly assigned to the experimental group or the control group. To evaluate the primary outcome measures and secondary outcome measures and to observe the incidence of organ and vascular injury. Finally, we evaluate the safety and efficacy of the test product through the comparison of the data obtained from the experimental group and the control group during the treatment.
