A highly simulated laparoscopic surgery simulation trainer

Abstract

A highly simulated laparoscopic surgery simulation trainer, including: a simulated human abdomen unit, using silicone to simulate human abdominal skin, composed of detachable anterior abdominal wall skin and back skin, the two parts of skin are connected by a sealing buckle to ensure that the entire simulated human abdomen The tightness; the animal liver set in the simulated human abdominal unit; the simulated pipeline system set in the simulated human abdominal unit, the simulated pipeline system is connected with the animal liver, the present invention utilizes sealed silica gel to simulate the abdominal skin, from poking Inflate to form pneumoperitoneum, and then use the pump group to realize human blood circulation under physiological conditions. The real animal liver passes through the inferior vena cava, portal vein, hepatic artery, and biliary tract and the inferior vena cava, portal vein, hepatic artery, and biliary tract of the simulator training system. They can be anastomosed separately, and various simple or complex laparoscopic surgery training can be carried out.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a laparoscopic training device, in particular to a highly simulated laparoscopic operation simulation training device. Background technique [0002] Since Philipe Mouret, a Frenchman, performed the first laparoscopic cholecystectomy in 1987, laparoscopy has experienced more than 20 years of development and has become a relatively independent discipline, and has derived minimally invasive procedures such as thoracoscopy, arthroscopy, and cranial laparoscopy. Surgical approach. [0003] Laparoscopic surgery is to make 2-5 incisions of about 1 cm in the abdomen and (or) waist of the human body, and insert a tube-shaped working channel called "trocar" into each. The operation is performed by trocar using special instruments for laparoscopy. Laparoscopic surgery has less trauma and faster recovery, which greatly reduces the pain of patients and shortens the length of hospital ...

AI Technical Summary

Problems solved by technology

Laparoscopic simulators can only simulate basic operations such as cutting, separation, ligation, etc., but cannot simulate the physiological environment of the human body and real surgical scenarios; the virtual laparoscopy simulation system can simulate surgical scenarios, but it is not realistic enough, and can also simulate relatively complex procedures. Surgical environment, but the operation perception feedback during surgery is not enough, and the price is expensive, which limits its wide-scale promotion and use
