Percutaneous nephroscope lithotripsy and lithotripsy training model and preparation method thereof

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, ...

AI Technical Summary

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 human tissue is a complex multi-layer material, and because its properties depend on the number of layers, the thickness of the layers, the direction of muscle fibers, humidity, temperature, etc., the tactile feel of the 3D simulation is always Failure to meet clinical needs;

[0006] 4) Animal surgery requires supporting conditions such as animal operating room, temporary animal breeding room, and anesthesia equipment. The investment cost of venues, personnel, and equipment is high, and the convenience is small. It does not form the operability of daily training. In addition, it is like isolated pig kidneys. It cannot provide doctors with the environment of perirenal fat wrapping and the pathological state of renal cysts;
