Laparoscopic cholecystectomy training device and method based on 3D printing technology

Abstract

The invention relates to the technical field of laparoscopic cholecystectomy training, in particular to a laparoscopic cholecystectomy training device and method based on a 3D printing technology. The training device comprises a device body, and the device body is provided with a simulation platform and an organ model. The simulation platform comprises a blood simulation platform and an abdominal cavity simulation platform, and the organ model comprises a gallbladder tissue model and a bleeding point model; the gallbladder tissue model is arranged at the abdominal cavity simulation platform and used for simulating the gallbladder tissue form, and the bleeding point model is arranged at the abdominal cavity simulation platform and used for simulating the blood vessel bleeding position; and the bleeding point model is communicated with the blood simulation platform through a pipeline, and the blood simulation platform is used for providing simulated blood for the bleeding point model. The training method is realized based on the training device. According to the invention, the simulated training of trainees can be better realized, and especially the simulated training of organs in different abnormal forms can be better realized, so that the training of doctors can be better realized.

Description

technical field [0001] The present invention relates to the technical field of laparoscopic cholecystectomy training, in particular to a laparoscopic cholecystectomy training device and method based on 3D printing technology. Background technique [0002] In laparoscopic cholecystectomy, due to the severe limitation of field of view and operating space, it requires high surgical skills and experience of the doctor, and the existing related researches also focus on how to carry out the operation of related tissues or organs during the operation. Search. For example, in the article "Application value of retrograde tracing along the 'cystic duct' in the prevention of extrahepatic bile duct injury in laparoscopic cholecystectomy" in Volume 28, Issue 2 of "Chinese Journal of General Surgery", an intraoperative Use the retrograde tracking method along the "cystic duct", that is, after separating the considered "cystic duct", dissociate retrogradely against the "cystic duct" towar...

AI Technical Summary

Problems solved by technology

However, at present, in laparoscopic cholecystectomy, there is still a lack of a better surgical training model, and the cost of 3D printed models is often relatively expensive, which has also caused great limitations to this type of surgical training.
