Embodiment 1

[0031] This embodiment provides a ligation device for laparoscopic ligation, including an end cap, a base, and a thread cutting device; wherein:

[0032] The center of the end cap is provided with a first through hole for passing through the ligature and fixing the ligature;

[0033] The central part of the base is provided with a second through hole adapted to the position of the first through hole, which is used to pass through the ligature; the surrounding of the second through hole is provided with a first base spring fixing seat, a second base A spring fixing seat and a blade fixing seat; the base is also provided with a side through hole;

[0034] The thread cutting device includes a first blade, a second blade and a pulling wire, the first ends of the first blade and the second blade are stacked and fixed on the blade fixing seat; the first ends of the first blade and the second blade The two ends are respectively bolted to one end of the pull wire, and the other end o...

Embodiment 2

[0040] This embodiment provides a laparoscopic device for laparoscopic ligation, including a laparoscope body and the ligation device provided in Embodiment 1, the ligation device is installed at the end of the working channel of the laparoscope body, and the working channel is simultaneously As the passing channel of the ligature wire and the pulling wire, it can be used as a variation example of Embodiment 1.

[0041] Further, the cavity mirror body adopts an existing common cavity mirror.

[0042] This embodiment will be further described below in conjunction with the accompanying drawings.

[0043] The ligation device is fixed at the end of the ordinary endoscope, and the ligation device is divided into upper and lower parts, the upper part is the top end cover 1, and the lower part is the base 2. There is first through hole 15 in the center of top end cover 1, and ligature thread can pass through, because the diameter of ligature knot is bigger, be stuck outside the thro...

Abstract

The invention provides a ligation device for an endoscopic ligation operation and an endoscope device. The ligation device is arranged at the tail end of a working channel of the endoscope body. The ligation device comprises a top end cover, a base and a trimming device, wherein the center of the top end cover is provided with a first through hole; the center of the base is provided with a second through hole matched with the first through hole in position and a side through hole; a fixing seat is arranged around the second through hole; the trimming device comprises a first blade, a second blade and a traction line; one end of the first blade and one end of the second blade are fixed on a blade fixing seat in an overlapping mode, and the other ends are tied with one end of the traction suture. The ligation device of the invention is fixed at the top end of the working channel of a common endoscope, and the pull line passes out of the working channel. The device is simple, the operation is easy, and the existing mechanism does not need to be changed; as the device is fixed at the tail end of the common endoscope, a suture end left on the suture knot is short and small, foreign bodies left in the body are reduced, discomfort of a patient is relieved, possibility of error operation is reduced, and the one-time success rate of the operation is improved.

Description

technical field [0001] The invention relates to a ligation device in the technical field of medical instruments, in particular to a remote operation ligation device and a laparoscopic device for laparoscopic ligation. Background technique [0002] As a therapeutic measure, ligation has a large-scale application in the medical field. Especially the ligation of the left atrial appendage has a very good effect on the treatment of atrial fibrillation. A large part of the current ligation operation is still done manually by doctors. In order to have enough working space, the incision in the usual ligation operation has the defect that the incision is too large, and at the same time, it is difficult to completely block the blood flow by manual operation. [0003] Faced with the above problems, the medical field is now slowly promoting the use of laparoscopic ligation. But now there are few laparoscopes for ligation, and the hospital does not have enough experience to complete t...
