A teaching model for suturing and knotting exercises in anorectal surgery

Abstract

The invention discloses a teaching model for suture and knotting exercises in anorectal operation, and particularly relates to the technical field of medical instruments. According to the teaching model, a tube body, a fixator, a push block, a colloidal silica body and a silicone rubber mucous membrane are designed, the tube body is a cylinder with two through ends and an opening formed along a generatrix, a fixing connector is arranged on the circle of the front end of the tube body, the inner wall and the outer wall of the tube body are connected together to form an outer cavity, and the outer cavity is used for containing the silicone rubber mucous membrane, namely simulating the human rectum shape; the silicone rubber mucous membrane which is curled into the cylindrical shape is supported and cannot deform after being used for a long time, so that the suture practice of students is not influenced; by designing the silicone rubber body, under the effect of a tractor, an operation scene can be simulated, and students can be placed in the operation scene closer to the real operation scene.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a teaching model for anorectal suturing and knotting exercises. Background technique [0002] The rectum is the last section of the digestive tract. Because there is a very rich connective tissue space around the middle and lower rectum, the rectum is less likely to be traumatized under normal trauma conditions. However, once the rectum is perforated, it may cause extremely serious perforation. Interstitial infection and a series of related complications. Therefore, rectal trauma is not only difficult to deal with, but also has many postoperative complications, which will cause great pain to patients and their families. Therefore, timely and effective processing is very important. For rectal trauma, the rectal wound is generally sutured and repaired to facilitate healing, and suturing refers to closing or rebuilding the channel of the cut or traumatic tissue or organ to...

AI Technical Summary

Problems solved by technology

[0006] 1. In the actual operation process, the silicone mucous membrane that is rolled into a cylindrical shape is easily deformed after a long period of use because there is no support inside, which leads to the failure of simulating the human rectal mucous membrane

[0007] 2. The lifting operation platform needs to adjust the four lifting rods separately, which is cumbersome to operate, and because the lifting rods are not integrated, there will be uneven height adjustments during adjustment, resulting in uneven placement of the operation table and affecting practice

[0008] 3. The silicone mucous membrane placed in the intestinal tube has a limited area to be practiced. When it is necessary to practice on the silicone mucous membrane behind, the fixing buckle must be opened again, and the tube body is opened to re-place the silicone mucous membrane. The operation is cumbersome

[0009] 4. In the operating table, the operating lights are often on the operating table, not in the operating position. The addition of light sources to the device deviates from the simulation of the surgical situation

[0010] 5. Because the rectum is connected to the anus, and the device lacks the simulation of the anus structure, it lacks a real simulation feeling, and cannot put students into a more realistic practice scene
