Simulation model used for ureteroscope operation simulation

Abstract

A simulation model for ureteroscopic surgery simulation, comprising: simulated ureter; simulated renal pelvis communicated with the simulated ureter; simulated renal calyces communicated with the simulated renal pelvis; the simulated renal calyx, simulated renal pelvis and simulated ureter include An inner tube and an outer tube surrounding the inner tube, with a cavity between the inner tube and the outer tube, the inner tube is used to simulate the inner wall mucosa of the human calyx, renal pelvis and ureter, and the outer tube is used to simulate the human body The outer walls of the renal calyx, renal pelvis, and ureter, the cavity used to hold fluid and keep it sealed during surgical training. Using this solution, during the operation simulation process, the cavity between the inner and outer tubes is filled with liquid to simulate blood. When the inner tube ruptures and the liquid flows out, the instructor can remind the students that the operation is wrong, and perforation and bleeding occur. complication. The ureter operation training model of the technical proposal can be used to simulate bleeding and perforation complications in the operation, and provide students with a realistic operation operation scene.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a simulation model for ureteroscopic surgery simulation. Background technique [0002] In the field of medical technology, ureteroscopic lithotripsy uses a flexible mirror with a diameter of about 3mm to insert the ureter through the urethra and bladder to crush and remove ureteral or kidney stones. Ureteroscopic surgery has technical advantages such as minimally invasive surgery. At the same time, it is difficult to operate and has a long learning curve. Practicing directly in the patient's body is undoubtedly contrary to medical ethics and will increase the risk of surgery. Modern and future patients are different from the past. They are unwilling to become "models" for physician training. The huge training needs call for an ideal training model. [0003] A wide variety of ureteroscopic surgery simulators have been developed over the past few decades for the training o...

AI Technical Summary

Problems solved by technology

[0004] The problem solved by the present invention is that the existing simulation simulators are limited to simulating the above-mentioned basic surgical operations, and cannot simulate common bleeding and perforation complications in clinical practice, and cannot accurately reflect the correct operation level and progress of trainees
