Description

Operation suture training device

Technical Field

The utility model belongs to the technical field of medical training apparatus, relates to a training device for surgical operation, in particular to a training device for suturing under the operation conditions of simulating different angles, positions, needle-moving tracks and the like.

Background

Suturing is one of the four basic functions of surgical skill and is the most difficult skill to master. The surgery is generally divided into destructive surgery of simple excision, operation of anatomical reconstruction and operation of functional reconstruction, and the difficulty and the requirement are gradually increased. Both of the latter two require superior suturing skills, the quality of the suture technique being accomplished, directly affecting the effectiveness of such procedures. In the first category of resection surgery, the greatest difficulty is hemostasis, the most difficult of which is also the need to be accomplished by suturing. Therefore, suturing is the most important technique in surgery. On the other hand, suturing is also the most difficult link to learn in surgery, especially suturing under a cavity mirror in deep tissue exposure and minimally invasive surgery.

The difficulty of suturing is that needles with different radians are required to be used, so that the moving track of the needles in the tissues needs to meet the anatomical physiological characteristics of the tissues, namely, the needles with fixed radians are used for suturing specific tracks, such as straight lines, irregular arcs or other curves, and the needles are required to be withdrawn along the radians to meet the requirements of the tissues and the actual situation in the operation. When the tissues are well exposed and are positioned at the center position parallel to the operation central line and the suture track is the most regular arc, the suture is most easily completed, which is also the scene of the setting of the common suture training device. The difficulty increases when the spatial position of the tissue to be sutured changes and is obstructed by various organ tissues from the operation instrument.

The suture difficulty under the laparoscopic surgery is further increased. Because the operation hole is fixed, the needle holding instrument is fixed at one point during suturing, the operation can be performed only by taking the point as the center, the needle operation is more strictly limited, and the suturing difficulty is extremely increased. In early laparoscopic surgery, each needle stitch required about half an hour and required special instrument assistance. Even though the most advanced robot-assisted laparoscope is available, the machine can carry out needle manipulation in three-dimensional space, and can realize a needle manipulation mode similar to an open operation under a minimally invasive condition, but the machine still needs to be operated by people, so that the machine also needs to be trained to be well mastered.

As such, the quality of the completion of the surgery is often limited by the quality of the suture, particularly in reconstructive surgery, especially endoscopic ones. Such as suturing for renal resection, urethral reconstruction for radical prostate cancer treatment, ureteral bladder replantation, renal pelvis shaping, bile duct-intestinal duct anastomosis, pancreatic duct anastomosis, and the like. Poor suturing results in tissue tears, strictures, leakage of urine, intestinal fistulas, pancreatic fistulas, and the like. In particular, one usually only pays attention to the completion of the operation, and the completion quality is usually more concealed because suturing can be always completed, and the completion quality of suturing can be greatly different, but is very important for the operation and the patients.

Thus, the learning curve of the suture is an important part of the learning curve of the surgery for the surgeon, and the effect of the surgery performed and the patient's healing are directly influenced by the suturing technique. The existing suture training system has a suture link, but has no specially designed suture training device. As described above, it is common to sew the suture with gauze, latex, or the like in a straight line or a diagonal line. The simulation degree of the method is the suture under the simplest condition, and the method is greatly different from the actual requirement in the operation.

Specifically, the current training method lacks complex needle clamping and adjusting, has serious defects in condition simulation in the operation, lacks training in aspects of three-dimensional space operation of a needle holder, needle clamping at various angles, fine control of needle adjusting and the like, and causes that a trainer lacks mastering of the operation of the needle holder by arms and wrists and lacks fine control of training of needle clamping at various angles, needle adjusting, needle transferring and needle discharging of suture needles, so that the suture training effect is difficult to meet the complex requirements in the operation.
