Problems solved by technology

[0003] The current training methods for doctors are as follows: 1) The use of dry modules (bean clamping, ferrule, perforation, paper-cutting, silicone imitation meat, etc.) can only train basic abilities such as spatial sense conversion, hand-eye coordination, and hand coordination, and the skill coverage is small. , cannot meet the needs of human surgical operations (such as the use of energy devices and surgical procedures, etc.);
[0004] 2) Although a single isolated organ allows doctors to train real touch and energy equipment, it lacks lesions and distortion, and can only allow doctors to practice individual techniques such as suturing and cutting;
[0005] 3) Although the 3D simulator is relatively convenient, the hu

preparation example Construction

[0063] In a second aspect, the present invention provides a method for preparing a percutaneous nephrolithotomy training model, comprising the following steps:

[0064] a. Open the kidney, place a stone in the calices, and close the kidney;

[0065] b. Wrap the kidney obtained in step a with simulated fat, and place it in a container;

[0066] c. Filling the container described in step b with an ultrasound-permeable material to prepare a percutaneous nephrolithotripsy training model.

[0067] It should be noted that the angle at which the kidney is placed in the container can be placed with reference to the position of the kidney in the human body, for example, the kidney is placed in the container at an angle of 30 degrees.

[0068] The preparation method of the percutaneous nephrolithotomy lithotripsy training model provided by the present invention is simple and quick, convenient for obtaining materials, and low in cost.

[0069] In some preferred embodiments, the means o...

Abstract

The invention provides a percutaneous nephroscope lithotripsy and lithotripsy training model and a preparation method thereof, and relates to the technical field of medical treatment. The percutaneous nephroscope lithotripsy and lithotomy training model comprises a container, an ultrasonic permeable material, simulated fat and a kidney, the container is filled with the ultrasonic permeable material, the kidney is wrapped by the simulated fat, the simulated fat is fixed in the ultrasonic permeable material, the simulated fat comprises chicken fat, leaf fat or animal fat, and the kidney is fixed in the simulated fat. The perirenal fat texture and perirenal substance filling can be fully simulated; and stones are fixed in the kidney calyx of the kidney. The training model is convenient to take materials, fully simulates touch and force feedback of real operation, and can be used for training of kidney ultrasound image recognition, puncture, expansion, lithotripsy and the like, so that medical staff can obtain real skill training touch, and surgical skills are improved; the training model is simple in training environment requirement, saves investment of sites, labor and the like, and realizes daily operation training.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a percutaneous nephrolithotripsy training model and a preparation method thereof. Background technique [0002] With the rapid development of contemporary science and technology, medical technology is changing with each passing day. However, most surgeons still use the teaching mode of "teaching by master and apprentice" and "training with surgery". In order to provide doctors with sufficient opportunities to accumulate skills and reduce the risk of practicing medicine. Surgery has extremely high requirements for doctors' operational proficiency. If doctors want to acquire effective skill accumulation, they need a lot of realistic training. [0003] The current training methods for doctors are as follows: 1) The use of dry modules (bean clamping, ferrule, perforation, paper-cutting, silicone imitation meat, etc.) can only train basic abilities such as spatial sense conversion, ...
