A Study About Remote and Local Liver Surgery

The goal of this clinical trial is to learn if the robotic surgical system producted by Shenzhen Edge Medical Company has a non-inferior textbook outcome in liver surgery in the field of remote surgery compared to local robotic surgery. It will also learn about the safety of remote liver surgery. The main questions are: Does remote liver surgery not lower the textbook outcomes in liver surgery compared to the local robotic surgery? What complications do participants have when taking remote liver surgery? Investigators will compare remote liver surgery to local robotic liver surgery to see if remote liver surgery doesn't lower the textbook outcome in liver surgery. Participants will: Undergo remote or local robotic liver surgery according to the random program; Visit the clinic in 3, 28 and 42 day after surgery for checkups and tests; Keep a diary of their postoperative complications.
