Description

A surgical suture trainer

technical field

The utility model belongs to the technical field of medical training equipment, and relates to a training equipment for surgical operations, in particular to a training device for suturing under surgical conditions such as simulating different angles, positions and needle trajectories.

Background technique

Stitching is one of the four fundamentals of surgical technique, and it is the most difficult to master. Surgery is usually divided into destructive surgery of simple excision, anatomical reconstruction surgery and functional reconstruction surgery, and the difficulty and requirements gradually increase. The latter two require superb suturing skills, and the quality of the suturing technique directly affects the effect of this type of surgery. In the first type of excision surgery, the biggest difficulty is hemostasis, and the most difficult part of hemostasis is suture. Therefore, suturing is the most important skill in surgery. On the other hand, suturing is also the most difficult part to learn in surgery, especially in the suturing of insufficiently exposed deep tissue and endoscopic suturing in minimally invasive surgery.

Fundamentally, the difficulty of suturing lies in the use of needles with different radians, so that the running trajectory in the tissue needs to conform to the anatomical and physiological characteristics of the tissue, that is, a needle with a fixed radian is used to suture a specific trajectory, such as straight lines and irregularities. Arcs or other shapes, and needles also need to follow the arc, in order to meet the needs of the organization and the actual operation. Suture is easiest to complete when these tissues are well exposed and located in a central position parallel to the operating centerline, and the suture trajectory is the most regular arc, which is also the setting of the usual suture trainer. When the spatial position of the tissue to be sutured changes, and it is obstructed by various organs and tissues between the target and the operating instrument, the difficulty increases to varying degrees.

The difficulty of suturing under laparoscopic surgery is further increased. Because the operation hole is fixed, the needle-holding device is fixed at one point during suturing, and the operation can only be performed with this point as the center. The needle movement is more strictly restricted, and the difficulty of suturing is extremely increased. In early laparoscopic surgery, each suture took about half an hour and required special instruments. Even today's most advanced robot-assisted laparoscopy, although the machine itself can perform needle movement in three-dimensional space and can achieve a needle movement mode similar to open surgery under minimally invasive conditions, the machine still requires human operation, so it also needs to be carried out. Training to master it well.

Therefore, the completion quality of surgery is often limited by the completion quality of suture, especially in reconstructive surgery, especially endoscopic reconstructive surgery. For example, suture in partial nephrectomy, urethral reconstruction in radical prostatectomy, ureteral bladder reimplantation, renal pelvis, bile duct intestinal anastomosis, pancreatic duct anastomosis, etc. Poorly completed sutures will cause serious consequences such as tissue tearing, duct stenosis, urine leakage, intestinal fistula, and pancreatic fistula. In particular, people usually only pay attention to whether the operation is completed, and the quality of completion is usually relatively hidden, because sutures can always be completed, but the quality of sutured completion varies greatly, but it is extremely important to the operation and the patient.

Therefore, for the surgeon, the learning curve of suturing is an important part of the learning curve of the operation, and the effect of the operation and the prognosis of the patient are directly affected by the suturing technique. In the existing suture training system, there is a suture link, but there is no specially designed suture trainer. As mentioned above, gauze, latex, etc. are usually used, which are arranged in a straight line or oblique line for sewing. The simulation degree is the suture under the simplest conditions, which is quite different from the actual demand during the operation.

Specifically, the current training method lacks complex needle clipping and adjusting needles, the simulation of the intraoperative situation is seriously insufficient, and there is a lack of training in the three-dimensional space operation of the needle holder, needle clipping at various angles, and fine control of needle adjustment. The trainer lacks the arm and wrist to master the operation of the needle holder, and lacks the precise control of the various angles of the suture needle to clamp, adjust, and move the needle, making it difficult for the suture training effect to meet the complex requirements of the operation.
