Problems solved by technology

This method does not intuitively present the actual internal structure of the human body, and may even mislead the basic techniques. Some minimally invasive surgical instruments cannot be trained (such as electrocoagulation). In-box performance

Abstract

The invention discloses a virtual laparoscopic common bile duct exploration training system which comprises the following modules: a physical modeling module, a random gall-stone generation module, an expert demonstration module and a stepped training module, wherein the physical modeling module is used for generating a human body model and various surgical instruments needed by virtual laparoscopic surgery; the random gall-stone generation module is used for randomly generating common bile duct stones; the expert demonstration module is used for playing stored expert operating information; and the stepped training module is used for training key operating procedures.

Description

technical field [0001] The invention relates to the technical field of virtual operation teaching, in particular to a virtual laparoscopic biliary tract exploration training. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive surgical method. It has been more than 100 years since Frenchman Mouret performed the first laparoscopic cholecystectomy. This technology has the advantages of small wound, quick recovery, less pain for patients, shorter hospital stay, etc., and is welcomed by patients and doctors. However, the implementation of laparoscopic surgery requires the superb skills of doctors, which is limited by surgical experience and can only be obtained through training and clinical practice. [0003] The existing laparoscopic surgery training system is mainly based on the simulation operation box. The operation box is used to simulate the body cavity of the human body, and some small balls, wires and other objects are placed insid...
