Description
Technical Field
The utility model relates to a be applicable to the intestinal canal and sew up teaching aid, concretely relates to intestinal canal is sewed up and is used testing arrangement.
Background
Intestinal anastomosis is a very important technique in surgical operations, and in actual surgical operations, a suturing operation needs to be performed on an intestinal tube. This operation has high requirements for the needle pitch, the suture tension, and the mastery of different suture techniques during the operation. The human intestinal wall has a complex structure and consists of a serosal layer, a muscular layer, a submucosal layer and a mucosal layer, and the modes of full-layer continuous suture and serosal layer reinforced suture can be selected in the suture process, and the suture modes are very important in the surgical operation process and are suture modes which need to be mastered by surgeons.
Specifically, in the clinical practical operation process, the needle feeding point is 4-5mm away from the incisal margin of the intestine to be sutured, and the distance between the needles is 3-4 mm. If the distance between the needle inlet point and the incisal margin is too large, the tissue sewed in is too large, the intestinal canal turns inwards, and intestinal obstruction is caused, and if the distance between the needle inlet point and the incisal margin is too small, the tissue is easy to tear. Too large needle spacing can result in incomplete intestinal closure, leakage of gas and leakage of fluid, and too small needle spacing can result in ischemia of local tissues to affect healing.
The amount of tension at the last knot of the suture is also important to the effectiveness of the suture. If the knotting tension is too large, the local ischemic necrosis of the intestinal canal can be caused, and the severe patients can directly cause the intestinal canal to be torn, thereby causing huge life risks to the patients. If the knot tension is too low, an intestinal fistula is likely to form, which may cause intestinal contents to flow out, leading to diseases such as peritonitis.
In current clinical teaching, the following problems exist:
1. the existing intestinal canal suture model only has one layer of silica gel material, cannot simulate a structure with different multilayer toughness of the intestinal canal wall in clinic, and cannot train multilayer continuous suture and a serous muscle layer strengthening suture technology.
2. No mark is arranged on the surface of the intestinal canal, so that the evaluation of the student needle spacing and the needle insertion point by the teaching personnel is stopped at the stage of visual observation and ruler measurement, and the evaluation and measurement are inconvenient.
3. The knotting tension of the students at the end of sewing cannot be accurate and visualized, and the students cannot grasp the knotting tension conveniently.
4. The existing intestinal canal anastomosis model lacks the evaluation on the actual effect (whether leakage occurs) of the suture after the suture, which is also the main limit point of the current intestinal canal anastomosis model.
The existing measurement of the knotting tension of the intestinal canal cannot be evaluated in a digital mode, can be measured only according to experience, and is not suitable for modern teaching. In conclusion, students use the existing silica gel model with single level as an examination training device, and clinical practice proves that even if the students use the clinical model for training for a long time, the students still cannot meet the requirements of clinical practical operation.
