Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Single-incision laparoscopic surgery is a surgical procedure in which multiple laparoscopic instruments are placed through a single small incision. It has the advantages of less surgical trauma, better cosmetic results and less postoperative pain compared with conventional laparoscopic surgery. However, the technical challenges and difficulties, including loss of triangulation, parallel coaxial effect, difficulty of achieving correct exposure, shared fulcrum, lack of ergonomic favorable position, etc. limited its widespread use. Robot-assisted laparoscopic surgery have significant advantages such as minimally invasive, delicate, and flexible, which can greatly expand the surgeon's surgical capabilities and effectively solve the various problems faced by traditional surgery. Therefore, robotic assisted single-port surgery is attracting increasing attention. This study is to investigate the safety of a novel single-port robotic system for general surgery.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Single-port Endoscopic Surgical System

A novel robotic surgical system that can be configured for multi-port, single-port, or hybrid-port procedures. In the single-port configuration, a four-channel trocar shall be used. The surgical tools are steered through the curved access channels in the trocar to enter a patient's abdomen.

Group Type EXPERIMENTAL

Robotic assisted single-port general surgery

Intervention Type PROCEDURE

Robot assisted single-port rectal resection, colectomy, partial gastrectomy, appendectomy and cholecystectomy via the single-port configuration
