Bionic gastrointestinal tract operation model capable of being cut by electrotome and manufacturing method thereof

Abstract

The invention discloses a bionic gastrointestinal tract operation model capable of being cut by an electrotome and a manufacturing method of the bionic gastrointestinal tract operation model. The operation model comprises a diaphragm model, a stomach model, a mesangial model and a small intestine model. The stomach model is connected with the diaphragm model, the mesangial model and the small intestine model. The bionic gastrointestinal tract operation model is prepared by taking a hydrogel compound as a main body matrix material, and the hydrogel compound also comprises an additive. Accordingto the bionic gastrointestinal tract operation model capable of being cut by the electrotome, hydrogel and a compound of the hydrogel are used as main materials. Through blending of hydrogel and compound material components and 3D printing or mold forming, the model is lifelike in hardness and touch and simulated in size and structure, the electrotome and ultrasonic scalpel effect and texture ofhuman tissue and organs can be simulated, and therefore gastrointestinal surgery operation processes such as a nissen fundoplication and a weight reduction surgery can be truly simulated.

Description

technical field [0001] The invention relates to an electric knife cuttable bionic gastrointestinal tract operation model, which belongs to the field of medical teaching instruments. Background technique [0002] Traditional surgery mainly uses "cold weapons" such as ordinary scalpels as surgical tools, but due to active wound bleeding after cutting, it should be used in operations with a lot of bleeding in a controlled manner. With the development of science and technology, electrosurgical instruments such as electric knife and ultrasonic knife have appeared, which have revolutionized the operation, greatly shortened the operation time, reduced the difficulty of operation, and the amount of blood loss in the same operation has decreased significantly compared with the past. When the high-frequency and high-voltage current generated by the electric knife passes through the high-impedance tissue through the electrode tip, heat will be generated in the tissue, causing the tissu...
