Description

Combined tissue perforation suture device

The invention relates to a combined tissue perforation suturing device, belonging to the field of medical instruments, and mainly used for suturing sutures of tissue perforations under endoscope.

Background technique

At present, when digestive endoscopy, especially soft endoscopy, is performed in digestive tract surgery, especially when mucosal dissection is performed, it is easy to cause tissue perforation, such as gastric perforation and intestinal perforation. Once perforation occurs, the endoscope is very remedy. Difficulties can cause very high risk to patients. At present, there is no device that can treat perforation very quickly. The existing hemostatic clip can only cope with small bleeding wounds, so endoscopic perforation and suture technique is urgently needed. problem.

Summary of the invention

The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art, and to provide a combined tissue perforation suturing device capable of rapidly achieving hemostasis suture at a perforation site under a digestive endoscope, thereby avoiding a medical accident.

In order to solve the above technical problem, the first technical solution of the present invention is: a combined tissue perforation suture device comprising a pull wire and at least two tissue perforation suturing devices, the tissue perforation suturing device comprising a hemostatic clip and a release device, a hemostatic clip It is detachably mounted on the head end of the release device, one end of the wire is fixed on the hemostatic clip of one of the tissue perforating suturing devices, and the other hemostasis of the tissue perforating stapler is provided with a threading hole through which the wire can be passed.

Further, the length of the pull wire is defined to facilitate use during surgery, and the other end of the pull wire extends to the tail of the release.

Further, there are two tissue perforation suturing devices.

Further, the release device includes a jacket, a handle, a movable release lever and a movable handle, the movable release lever is axially movably inserted in the outer sleeve, and the movable handle is disposed at a tail end of the movable release lever, The handle is placed at the end of the jacket.

In order to solve the above technical problem, a second technical solution of the present invention is: a combined tissue perforation suture device comprising a pull wire and at least two tissue perforation suturing devices, the tissue perforation suturing device comprising a hemostatic clip and a release device, a hemostatic clip It is detachably mounted on the head end of the release device, and the wire is also at least two, and corresponds one-to-one with the tissue perforating suturing device, and one end of the wire is fixed on the hemostatic clip of the corresponding tissue perforating suturing device.

Further, the other end of the pull wire extends to the tail of the corresponding release.

Further, there are two tissue perforation and suture devices. , ,

The movable handle is disposed at the rear end of the movable release lever, and the handle is disposed at the rear end of the outer sleeve.

After adopting the first technical solution, the perforation of the tissue is found under the digestive endoscope, and the hemostatic clip of the tissue perforating suture device with the wire is attached to the edge of the perforated tissue, and the tissue is clamped, and then the hemostasis is clamped from the release device. Separate, the other end of the pull wire protrudes out of the body through the endoscopic forceps hole, and then the wire is passed through the threading hole above the hemostatic clip of the other tissue perforating suture device, the hemostatic clip is pulled down to the perforation, and the perforation is further Hold the edge of the tissue at one end, and then clip the hemostasis clip on the remaining tissue perforation device to the edge of the remaining tissue, then tighten the wire, slowly close all the hemostatic clips, tighten the perforated tissue, and of course, by pulling The wire is equipped with a locking block, and the locking block is fixed to the edge of the last hemostatic clip and the wire is fixed. The hemostatic clip is closed and tightened by the locking block, so that the hemostasis suture of the perforation site can be quickly realized under the digestive endoscope, and the tissue wound is closed. The purpose of surgical treatment is achieved to avoid the occurrence of medical accidents.

After adopting the second technical solution, the tissue perforation is found under the digestive endoscope, and the hemostatic clip of the tissue perforating suture device with the wire is attached to the edge of the perforated tissue, and the tissue is clamped, and then the hemostasis is clamped from the release device. Separate, the other end of the pull wire protrudes out of the body through the endoscopic forceps hole, and then the hemostatic clip of another tissue perforating suture device with a wire is attached to the edge of the tissue at the other end of the perforation, and clamps the tissue, and then hemostasis The clip is separated from the release device, and the other end of the pull wire is also extended out of the body through the endoscope clamp hole, and the hemostasis clip on the remaining tissue perforation suture device is sequentially clamped to the remaining tissue edge, and the other end of the pull wire is also passed through the endoscopic forceps. The hole protrudes out of the body, then tighten the wire, slowly close all the hemostatic clips, tighten the perforated tissue, of course, by placing a locking block on all the wires, and tightening the hemostatic clip through the locking block, so that It can quickly realize hemostasis suture on the perforation site under digestive endoscopy, so that the tissue wound can be closed to achieve the purpose of surgical treatment, thereby avoiding Health medical malpractice phenomenon.
