Technical Field
The utility model relates to a medical science training model technical field specifically is a minimal access surgery formula training model of simulation human organ is rebuild with animal organ.
Background
The laparoscopic minimally invasive surgery technology is mature, and has been accepted and recognized by the majority of people because of the characteristics of small trauma during the surgery, quick recovery after the surgery and the like, small and medium hospitals in China begin to popularize and develop the laparoscopic minimally invasive surgery, the minimally invasive surgery is more developed in hepatobiliary, gastrointestinal and urinary surgeries, and is also the department of the minimally invasive surgery developed by each comprehensive hospital firstly, but at present, all small and medium hospitals lack talents who are skilled in mastering minimally invasive techniques, so that the medical personnel who quickly develop and master the skills of professional laparoscopic minimally invasive surgery become urgent needs, therefore, professional and systematic training platforms, models and courses are needed to meet the requirements, and the multidisciplinary minimally invasive skill training system is applied and is provided with a professional isolated organ of abdominal cavity for minimally invasive surgery training.
The traditional laparoscopic minimally invasive surgery model mostly adopts artificial materials made of silica gel and latex materials, and a pathological structure is simulated through mould shaping or 3D printing. However, the material can not simulate the real human tissue touch sense, has a great difference with the real clinical operation type application, and has little training and teaching significance.
SUMMERY OF THE UTILITY MODEL
In view of the problems in the prior art, the utility model discloses a minimally invasive surgery type training model for reconstructing and simulating human organs by using animal organs, which adopts the technical proposal that the model comprises abdominal cavity organs under animals, blood vessel perfusate and an organ tray; the animal lower abdominal cavity organ is placed on the organ tray according to the body position of the human lower abdominal cavity organ; the vascular perfusate is perfused into the lower abdominal cavity organ of the animal.
As the utility model discloses a preferably technical scheme of minimal access surgery formula training model with animal organ reconstruction simulation human organ, abdominal cavity organ contains liver, courage, pancreas, spleen, stomach, intestines, omentum and the corresponding complete ligament of animal at least under the animal and connects, and abdominal cavity organ can simulate real human abdominal cavity organ and possess real vision and sense of touch feedback under the application real animal.
As the utility model discloses an it simulates the preferred technical scheme of human organ's minimal invasive art formula training model to rebuild with animal organ, the blood vessel perfusate forms for artificial blood and anticorrosive fresh-keeping liquid ratio configuration, can simulate the intraductal true blood condition of human abdominal cavity ware under through the blood vessel perfusate.
As the utility model discloses an use animal organ to rebuild the preferred technical scheme of minimal access surgery formula training model of simulation human organ, anticorrosive fresh-keeping liquid adopts 5 kinds of constitutions in sodium chloride, streptomycin, alcohol, pure water, 200 mesh water-absorbing resin, ice-cube, the antistaling agent, comes fresh-keeping animal lower abdominal cavity organ through anticorrosive fresh-keeping liquid.
As the utility model discloses a with animal organ rebuild simulation human organ's the preferred technical scheme of minimal access surgery formula training model, the blood vessel perfusate is from spleen and stomach artery department and liver and stomach artery department pour into in the abdominal cavity organ under the animal.
The utility model has the advantages that: the utility model discloses an abdominal cavity organ possesses true vision and sense of touch feedback under the application real animal abdominal cavity organ can simulate real human body, can simulate the intraductal true blood condition of abdominal cavity organ under the human body through the vascular perfusate, and abdominal cavity organ under the animal keeps fresh through anticorrosive fresh-keeping liquid, the utility model discloses an animal in vitro tissue organ handles through special technology, and the moulding is tailor to the structurization and simulates real adult human body under abdominal cavity organ histopathology structure, possesses true vision and sense of touch feedback simultaneously. The operation process and the situation of the lower abdominal clinical endoscopic surgery type can be truly simulated, and the endoscopic surgery skill of the training doctor can be rapidly improved.

Detailed Description
Example 1
As shown in figure 1, the utility model discloses a minimally invasive surgery type training model for reconstructing and simulating human organs by using animal organs, which adopts the technical proposal that the model comprises abdominal cavity organs under animals, vascular perfusate and an organ tray; the animal lower abdominal cavity organ is placed on the organ tray according to the body position of the human lower abdominal cavity organ; the vascular perfusate is perfused into lower abdominal organs of animals, the soaked lower abdominal organs of animals are placed on an organ tray, the tissue is cut, 2 pages of liver tissues are adopted, blood vessels with broken organs are rebuilt, the ports are closed, preparation is made for subsequent blood perfusion, and the cut lower abdominal organs of animals are fixed in a special organ tray according to the body position of lower abdominal organs of human bodies.
As the utility model discloses an it simulates preferred technical scheme of human organ's minimal invasive surgery formula training model to rebuild with animal organ, abdominal cavity organ contains the liver, courage, pancreas, spleen, stomach, intestines, omentum and corresponding complete system ligament of animal at least and connects under the animal, abdominal cavity organ can simulate real human abdominal cavity organ possesses true vision and sense of touch feedback under through using real animal, cut out intestines and genitourinary system in the same direction as tissue line with the tissue, wash the content in the digestive system with the clear water, the surplus soaks for 2 hours after washing with normal saline and the special antiseptic solution of organ for reserve.
As the utility model discloses a rebuild preferred technical scheme of minimal access surgery formula training model of simulation human organ with animal organ, the blood vessel perfusate forms for artificial blood and anticorrosive fresh-keeping liquid configuration in proportion, can simulate the intraductal true blood condition of human abdominal cavity ware under through the blood vessel perfusate, and the blood vessel perfusate 1000ml (artificial blood and anticorrosive fresh-keeping liquid) of preparation in proportion are reserve.
As the utility model discloses an use animal organ to rebuild the preferred technical scheme of minimal access surgery formula training model of simulation human organ, anticorrosive fresh-keeping liquid adopts 5 kinds of constitutions in sodium chloride, streptomycin, alcohol, pure water, 200 mesh water-absorbing resin, ice-cube, the antistaling agent, comes fresh-keeping animal lower abdominal cavity organ through anticorrosive fresh-keeping liquid.
