Rigid ureteroscope/flexible ureteroscope teaching mold and preparation and operation methods thereof

Abstract

The invention provides a rigid ureteroscope/flexible ureteroscope teaching mold which comprises a urinary system model; artificial urine can be injected into the urinary system model to simulate the urine internal environment of a urinary system; the urinary system model comprises a kidney model, a bladder model, a ureter module, a calculus model, a urethra model and a fixing device; the kidney model is provided with a water injection port; and the kidney model, the bladder model, the ureter model and the urethra model are made of rubber materials. The invention further provides preparation and operation methods of the rigid ureteroscope/flexible ureteroscope teaching mold. According to the rigid ureteroscope/flexible ureteroscope teaching mold and the preparation and operation methods thereof, the defects that a urinary system teaching mold used for operation of a traditional rigid ureteroscope/flexible ureteroscope is low in simulation performance, single in stone lesion characteristic and poor in operability are overcome.

Description

technical field [0001] The invention relates to the technical field of application of teaching molds for urological surgery, in particular to a 3D printing technology-based teaching mold for ureteral hard mirror / soft mirror and its preparation and operation methods. Background technique [0002] With the changes in work, life rhythm, exercise, and eating habits in modern society, the incidence of urinary calculi is increasing year by year, which is a common disease of the urinary system. Stones can occur anywhere in the kidney, bladder, ureter, and urethra, but kidney and ureter stones are the most common. Therefore, transurethral pelvis / ureteroscopic lithotripsy has become one of the basic operations that urologists must master. At present, the urology departments of major hospitals have carried out teaching work of ureteroscopic hard or flexible ureteroscopy. [0003] With the development of science and technology, 3D printing has been applied in various fields. 3D prin...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is to provide a 3D printing technology-based ureteroscopic hard mirror / soft mirror teaching mold and its preparation and operation methods, and use a high-elastic rubber material with large reversible elastic deformation to simulate the urinary system. Texture, realize the internal environment of the cavity urine and pre-set and print stone lesions of different composition, shape, position and quantity, so as to meet the teaching requirements of lithotripsy surgery under different disease conditions. The urinary system teaching aids used in traditional ureteroscopy / flexoscopy operations have the defects of low simulation, single stone lesion characteristics, and poor operability
