Problems solved by technology

[0004] 1) Existing animal organs are used for skills training, but the animal organs purchased in the market have no blood vessels and lesions, and techniques such as injection hemostasis and ligation hemostasis cannot be practiced; they cannot be effectively used for esophageal and gastric varicose surgery simulation training
[0005] 2) Live animals are used for skill training, but live animals are also difficult to cultivate lesions. Animal surgery requires animal operating rooms, animal temporary breeding rooms, anesthesia equipment and other supporting conditions. The investment in venues, personnel, and equipment is high, and the convenience is small, making training The cost is very high, and it is difficult for ordinary doctors to have the opportunity to practice a lot to meet the skill requirements of actual human surgery
[0006] 3) The box-type simulator is used for skill training, but the simple box-type simulator can only train basic abilities such as spatial sense conversion, hand-eye coordination, and hand-hand coordination. needs (such as the use of energy devices and surgical procedures, etc.)
[0007] 4) Use 3D simulators for skill training, but human tissue is a complex multi-layer material, and because its properties depend on the number of layers, thickness of layers, direction of muscle fibers, humidity, temperature, etc., it is difficult to simulate in 3D

Embodiment 1

[0074] A kind of operation training model of esophageal and gastric fundus varices, the manufacturing method of the model is as follows:

[0075] Take a chicken intestine tube with a diameter of about 0.8 cm, and inject a mixture of 500 mL glycerin and 5 g carmine into the inside. Every 1-2cm is ligated into a section, such as figure 1 shown.

[0076] Cut a gap of 5 cm at the film position at the bottom of the minipig stomach, turn the stomach inside out, and fix the varicose blood vessels on the esophagus wall and the fundus of the stomach according to the direction of the lesion blood vessels. Fixation is performed at each ligated point. The longer section (1.5-2cm section) is fixed in the middle with a red silk thread. When fixing, use a needle and thread to pass through the mucosal layer, and then fix it. When fixing, the thread knot is hidden under the blood vessel. Simulate the flexion and bulging of varices in the esophageal and gastric fundus in humans, such as f...

Embodiment 2

[0079] A kind of operation training model of esophageal and gastric fundus varices, the manufacturing method of the model is as follows:

[0080] Take a duck intestinal tube with a diameter of about 0.5 cm, and inject a mixture of 500 mL glycerin and 5 g carmine into the inside. Every 1-2cm is ligated into a section.

[0081] Cut a 4 cm gap in the film at the bottom of the stomach, turn the stomach inside out, and fix the varicose blood vessels on the esophagus wall and the fundus of the stomach according to the direction of the blood vessels in the lesion. Fixation is performed at each ligated point. The longer section (1.5-2cm section) is fixed in the middle with a red silk thread. When fixing, use a needle and thread to pass through the mucosal layer, and then fix it. When fixing, the thread knot is hidden under the blood vessel. Simulates buckling and bulging of varices in the esophageal and gastric fundus in humans.

Embodiment 3

[0084] A kind of operation training model of esophageal and gastric fundus varices, the manufacturing method of the model is as follows:

[0085] Take a rabbit intestinal tube with a diameter of about 1 cm, and inject a mixture of 500 mL glycerin and 5 g carmine into it. Every 1-2cm is ligated into a section.

[0086] Cut an 8 cm gap at the bottom film of the cow's stomach, turn the stomach inside out, and fix the varicose blood vessels on the esophagus wall and gastric fundus according to the direction of the blood vessels in the lesion. Fixation is performed at each ligated point. Longer segments (1.5-2 cm segments) are fixed in the middle. The fixing method adopts glue. Simulates buckling and bulging of varices in the esophageal and gastric fundus in humans.

[0087] The stomach was turned back to its original state, the opening was ligated, and the shape of the stomach was restored to its original state to obtain a surgical training model for esophageal and gastric var...

Abstract

The invention provides an esophageal and gastric fundus varicose vein operation training model and a manufacturing method thereof, and relates to the technical field of medical treatment. The invention provides the esophageal and gastric fundus varicose vein operation training model. The esophageal and gastric fundus varicose vein operation training model comprises an esophageal and gastric module and a varicose blood vessel module fixed in the esophageal and gastric module. The esophageal and gastric module simulates the esophageal stomach of a human body; and the varicose blood vessel module is an animal intestinal canal injected with glycerin and pigment, the glycerin has no obvious influence on the animal intestinal canal, damage to the animal intestinal canal caused by injection of other liquids is avoided, storage of the animal intestinal canal is prolonged, and the varicose blood vessel module is ligated every 1-2 cm to simulate buckling and bulging of varicose veins in the esophageal and gastric fundus of the human body. The operation training model provided by the invention can fully ensure feedback of training operation touch and force so that a doctor obtains real and convenient skill training, the operation skill is improved, meanwhile, the training environment is simplified, and the investment of sites, cost, labor and the like is saved.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an operation training model of esophageal and gastric fundus varices and a manufacturing method thereof. Background technique [0002] Esophageal and gastric varices are a common disease in gastroenterology. Due to liver cirrhosis and other reasons, the blood passing through the liver is blocked, resulting in venous lesions. The veins in the gastric fundus and esophagus are flexed, and the blood vessel walls are thinned and easily damaged. Once damaged, because the blood vessels are in the stomach and esophagus, hemostasis is difficult, and the patient may be life-threatening due to excessive blood loss; one of the most important surgical treatments for esophageal and gastric varices is gastroscopic sclerotherapy of esophageal and gastric varices And ligation treatment; doctors need to operate gastroscope to inject drugs into gastric blood vessels to form thrombus to stop bleedi...
