Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a teaching model for surgical suturing and knotting practice in anus and rectum.
Background
The rectum is the last segment of the digestive tract, and because the middle and lower segments of the rectum have quite abundant connective tissue gaps around the rectum, the rectum has less chance of being injured due to general trauma, and once the rectum is punctured by trauma, the rectum is likely to cause extremely serious infection of the gaps around the rectum and bring a series of related complications. Therefore, the rectal trauma is not only very troublesome to treat, but also has many postoperative complications, which can cause great pain to patients and family members. Therefore, timely and effective processing is very important. Rectal trauma is usually repaired by suturing the rectal wound exactly to facilitate healing, and suturing refers to closing or reconstructing the channel of the cut or traumatized and fractured tissues and organs to restore the function of the tissues and organs. The knotting is the last step of ending the sewing and plays a role in fixing and reinforcing. Both of them are the basic conditions for ensuring good healing, and are one of the important basic operation techniques of surgery, and even more, every will becomes the doctor's course of repair.
Chinese patent documents: CN 108269475 a, application date: 2013.09.27, the patent names: a teaching model for anorectal operation suture and knotting practice. Discloses a teaching model for surgical suture and knotting practice in anorectal, which comprises an operation table, a fixed bracket, an intestinal canal, a silica gel mucous membrane and a light source; the operating platform is of a cuboid structure, and lifting rods are arranged around the bottom of the operating platform; the fixed brackets are arranged at the front end and the rear end of the surface of the operating platform; the intestinal canal is of a hollow expandable structure.
The teaching model for operation suturing and knotting practice in anus rectum of the patent literature provides a three-dimensional suture and knotting in the convenient student simulation anus rectum, improves the technique of sewing and knotting in the anus of student, environment when the at utmost reduction operation, the substitution sense of reinforcing student as the main sword when practising can be practiced repeatedly, experience repeatedly, provide a valuable teaching model for operation suturing and knotting practice in the anus rectum for the student really implements operation anus internally sews up and when knotting.
The problems of the current model are as follows:
1. in the actual operation process, the silicon gel mucosa which is curled into a cylindrical shape is easy to deform after being used for a long time because the inside of the silicon gel mucosa is not supported, so that the simulated human rectal mucosa fails.
2. Four liftable poles need be adjusted respectively to the lift operation panel, complex operation, and because the lifter is not integrative, just there is the condition emergence that the altitude mixture control differs when the adjustment, leads to the operation panel to place not level, influences the exercise.
3. The silica gel mucosa of putting into the intestines is practiced the area of being limited, just must reopen the fixed knot when needs to practise the silica gel mucosa in back, opens the body and replaces the silica gel mucosa, complex operation.
4. In surgical tables, often the surgical lights are all above the table, not in the surgical position, and the device incorporates light sources that are instead offset from the simulation of the surgical situation.
5. Because the rectum is connected with the anus, the device lacks the simulation of the anus structure, lacks the real simulation sense and can not place the student into a more real exercise scene.
