Background
In intestinal anastomosis, the intestinal resection step comprises: opening abdomen, cutting mesentery in sector, ligating to stop bleeding, cutting intestine, and anastomosing cut end; the process of intestinal anastomosis comprises: trimming the stump, sewing the whole layer, and embedding the serosal layer. The anatomical level of the small intestine generally has four parts: mucosa, submucosa, muscularis, and serosa. The existing intestinal anastomosis model has the following technical problems: (1) most of the rubber tubes are single-layer independent rubber tubes, and a layer of dye is brushed in the rubber tubes, so that the rubber tubes are separated from the actual abdominal cavity structure and are far from the intestinal anatomical structure; (2) during the suture process, the pipeline is only anastomosed independently, and the serosal layer embedding cannot be carried out; (3) the single pipeline only simulates the intestinal cavity and lacks the steps of mesentery separation, mesentery blood vessel treatment and the like; (4) the long-term repeated practice cannot be realized due to the limitation of materials and the like.

The free end of the simulated intestinal canal is also provided with a second connecting piece which can be a plastic hollow cylinder, and the outer diameter of the second connecting piece is equal to or slightly smaller than the diameter of the intestinal canal and is used for connecting the external intestinal canal. According to the examination requirement, if the intestinal end-end anastomosis is simply carried out, an external intestinal tube is not needed, if the end-side anastomosis is carried out, or the anastomosis after the excision of intestinal necrosis or the intestinal fistulization and the like can be connected with the intestinal tube, the purpose is that the model is jointed with the clinical reality and can be used for various operations.
Simulation intestines pipe, simulation mesentery blood vessel, simulation blood vessel etc. are removable substitution design in this application to realize the relapse multiple suitable for of model. Parts, connection relations, position relations and the like which are not described in the present application can be realized by any prior art.
Has the advantages that: compared with the prior art, clinical as far as possible is pressed close to this application teaching mode that the intestines are coincide, and the switch abdomen is practised in order to the simulation of abdominal cavity simultaneously, and the intestines are coincide to have abdominal cavity simulation seat can be truer, and the operation is more meticulous. The mesenteric blood vessel is designed to be included, can be fused into the blood vessel for ligation, and meets the requirement of blood vessel separation ligation under the condition of real intestinal anastomosis; the connecting device enables the model to be replaceable, replaces the connected intestinal canal according to actual requirements, can perform end-to-end anastomosis, end-to-side anastomosis and side-to-side anastomosis, and can be repeatedly used.
