Problems solved by technology

[0005] With isolated animal organs as the object of surgical training, due to the lack of lesions, only individual skills such as suture and cutting can be exercised; with live animals as the object of surgical training, the investment is high, and animal breeding rooms, anesthesia equipment, and surgical venues need to be provided, and There is a big difference between animals and humans; using beans or silicone imitation meat as surgical training objects can only train basic abilities such as spatial sense conversion, hand-eye coordination, and hand coordination, and cannot meet the needs of human surgery

Embodiment 1

[0092] A transabdominal preperitoneal hernia repair operation training model, the production method comprising the following steps:

[0093]1. Take the stomach tissue of the pig along the lesser curvature to remove the wrinkled and unsmooth gastric body of the lesser curvature of the stomach;

[0094] 2. Cut the gastric fundus and gastric body of the gastric tissue to obtain the gastric fundus and gastric body;

[0095] 3. The schematic diagram of gastric fundus is as follows: image 3 As shown, the mucosal layer and the seromuscular layer at the edge of the gastric fundus were separated by 0.5 cm; then the long axis AB of the gastric fundus was used as the folding line to fold in half, and the edge of the butt-joined mucosal layer was sutured from the A end to the B end, and the diameter of the B end was retained. 2.5cm opening; then two chicken intestines with a diameter of 0.8cm and a length of 12cm were placed between the separate mucosal layer and the seromuscular layer,...

Embodiment 2

[0101] A transabdominal preperitoneal hernia repair operation training model, the production method comprising the following steps:

[0102] 1. Take the stomach tissue of the sheep along the lesser curvature to remove the wrinkled and unsmooth gastric body of the lesser curvature of the stomach;

[0103] 2. Cut the gastric fundus and gastric body of the gastric tissue to obtain the gastric fundus and gastric body;

[0104] 3. Separate the mucosal layer and the seromuscular layer at the edge of the gastric fundus by 1 cm; then fold in half with the long axis AB of the gastric fundus as the folding line, and fix the edge of the butt-joined mucosal layer from the A end to the B end with a fixed pin and keep the diameter at the B end Then put two duck intestines with a diameter of 1cm and a length of 15cm between the separated mucosal layer and seromuscular layer, and one end of the duck intestine was sutured and fixed at the A end, and the inside of the duck intestine was filled ...

Embodiment 3

[0110] A transabdominal preperitoneal hernia repair operation training model, the production method comprising the following steps:

[0111] 1. Take the gastric tissue of the cow along the lesser curvature to reduce the wrinkled and uneven gastric body of the lesser curvature of the stomach;

[0112] 2. Cut the gastric fundus and gastric body of the gastric tissue to obtain the gastric fundus and gastric body;

[0113] 3. Separate the mucosal layer and seromuscular layer at the edge of the gastric fundus by 1.5 cm; then fold in half with the long axis AB of the gastric fundus as the folding line, suture the edge of the butt-joined mucosal layer from end A to end B, and keep the diameter of end B at 3.5 cm opening; then two chicken intestines with a diameter of 1.2 cm and a length of 18 cm were placed between the separated mucosal layer and seromuscular layer, and one end of the chicken intestine was fixed on the A end, and the inside of the chicken intestine was filled with wa...

Abstract

The invention provides a transabdominal preperitoneal hernia repair operation training model and a manufacturing method and a preservation method thereof, and relates to the field of medical technology. The preparation method of the training model for transabdominal preperitoneal hernia repair provided by the present invention takes gastric tissue as the main raw material, fully simulates the texture of the lesion tissue, as well as the structure of the actual lesion and the direction of blood vessels. Low. The training model for transabdominal preperitoneal hernia repair operation provided by the present invention is made from the main raw material of gastric tissue, and fully simulates the texture of the lesion tissue, as well as the tactile sensation and force feedback of real surgical operations, and provides a reliable training model for medical staff , improve surgical skills, and the training environment of the training model is simple, saves investment in space, cost, labor, etc., and realizes routine surgical training.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a transabdominal preperitoneal hernia repair operation training model and a manufacturing method and a preservation method thereof. Background technique [0002] Hernias are mostly in the abdomen, and external abdominal hernias are more common. Among them, inguinal hernia has the highest incidence rate, accounting for more than 90%, followed by femoral hernia, accounting for about 5%. The more common external abdominal hernias include incisional hernia, umbilical hernia and white line hernia, etc., and hernias cannot heal by themselves. In the early stage or with mild symptoms, the patient will experience symptoms such as pain, lower abdominal distension, indigestion and diarrhea. After the disease continues to develop, due to the lump falling into the scrotum, it will cause inconvenience in activities and walking. In severe cases, incarceration will occur. If it is not treate...
