Description

Traction suturing device under endoscope

Technical Field

The utility model relates to the field of medical instruments, in particular to a traction suturing device under an endoscope.

Background

The endoscope tissue clip has the characteristics of high hemostasis speed, low incidence rate of re-bleeding, capability of closing digestive tract mucosa so as to promote wound healing, definite curative effect and the like, is a conventional means for hemostasis of bleeding patients and wound closure after endoscopic surgery, and is very widely used clinically. The existing tissue clamps can be roughly divided into four types, the first type is a tissue clamp with a separated clamp and a device, the device can be reused, the clamp is disposable, and a doctor needs to assemble on site every time when using the tissue clamp, and the tissue clamp cannot be repeatedly opened, closed and repositioned. If the clip is released incorrectly, the above operation must be repeated once and one tissue clip is wasted. The device needs to be disinfected every operation, and if the device is not disinfected properly, the risk of cross infection exists. The second type is a tissue clamp with an integrated clamp and device, which can not be repeatedly opened and closed for repositioning, once released, the clamping point deviates from a target point, which not only causes the waste of the tissue clamp and the releasing device, but also brings trouble to the re-operation, delays the precious time for treating patients, but is simpler and more convenient than the first type in operation, and still can not solve the problem of accurate positioning. The third type of tissue clamp is a repeatedly openable and closable integrated tissue clamp, which can be repeatedly opened and closed in a natural cavity of a human body and can reposition a diseased part, but the diseased part is difficult to be accurately positioned in actual operation due to the peristalsis of the gastrointestinal tract. The fourth tissue clamp is a rotatable and repeatedly openable and closable integrated tissue clamp, can clamp and close target tissues by rotating and repeatedly opening and closing, can find a more proper point through rotation to clamp, the tissue clamp is the tissue clamp which is most applied at present, but in clinical use, the existing tissue clamp can only suture and clamp the small wound surface, the wound surface beyond the clamping distance can not be directly and perfectly clamped and can only be sutured by a nylon ring ligation device, the suturing mode has higher requirements on the operation technique of a doctor, the operation is difficult and the operation time is long, moreover, the material cost is high, and the key is that when the wound surface is closed, the two sides of the wound surface are difficult to be aligned and healed in a linear way, and the tissue clamp is retained in the wound surface, so that the wound surface is not favorable for the growth of the wound surface, the tissue laceration caused by the suture failure, incomplete suture, wound surface bleeding, formation of fistula, larger scars of the wound surface after operation and the like often occur.
