Description

A laparoscopic purse-string suture electrocoagulation device and its anastomosis mechanism

technical field

The invention relates to the field of medical instruments, in particular to a laparoscopic purse-string suture electrocoagulation device and an anastomosis mechanism thereof.

Background technique

In today's surgery, laparoscopic surgery has been widely used in clinical practice. Laparoscopic intestinal surgery usually requires cutting off the intestinal tract and then suturing, because laparoscopic surgery only makes a small incision in the abdominal wall, through the trocar and long rod With the cooperation of the instruments, it can be inserted into the abdominal cavity to perform partial resection and anastomosis of the digestive tract. Under this condition, the following problems will occur after cutting with a disposable laparoscopic linear cutting and stapler: 1. Due to the size of the intestinal tract and anastomotic jaws Inconsistent, the bowel width is smaller than the jaws, and the excess staples will fall on the bowel after anastomosis. 2. After the straight line cutting and anastomosis, the intestinal connection will cause the overlapping of the staples. 3. There may be more bleeding after surgery. Follow-up treatment such as suture or hemostatic powder should be applied to the wound. Because the surgical space is limited, it is very difficult to suture in the later stage, and the instruments will touch each other in it, which may affect the surgical effect. . There are also disposable electrocoagulation cutters, which can achieve electrocoagulation and hemostasis, but the above-mentioned problems of long operation time and large trauma have not been solved.

Although the existing electrocoagulation cutters on the market can solve the problem of intestinal bleeding at the incision margin, they cannot achieve closed cutting; while the disposable endoscopic linear cutting and stapler can cut and separate the intestines in a closed manner, avoiding the need for Tumor cells are exposed, but they are closed in both directions. When the two ends of the intestinal tract are anastomosed, there will be an overlap of staples, which prolongs the operation time.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide an electrocoagulation device for endoscopic cutting and anastomosis and its anastomotic mechanism, which can simplify the operation process of the operation and reduce the trauma to the operation patient. When the intestine is cut off, one side of the intestine can pass through. The purse-string suture was performed, and the other side of the incision edge was only hemostasis but not anastomotic by electrocoagulation.

The purpose of the present invention is to achieve this, an anastomosis mechanism of an endoscopic purse-string suture electrocoagulation device, which is detachably connected with the firing instrument 5; it includes an upper forceps portion 1 and a lower forceps portion 2;

The proximal ends of the upper jaw part 1 and the lower jaw part 2 are hinged to each other; between the upper jaw part 1 and the lower jaw part 2, a cutting knife that moves forward and backward is arranged, and the upper jaw part 1 and the lower jaw part 2 are divided to form a left side. , Two functional areas on the right, one of which is provided with a purse-bag anastomosis structure 3, and the anastomosis is achieved through the purse-bag anastomosis structure 3;

A laparoscopic purse-string suture electrocoagulation device includes the above-mentioned anastomotic mechanism.

The advantages of the present invention are:

1. Through a single operation of laparoscopy, the closure of the intestine, the cutting of the intestine, and the electrocoagulation of the intestinal incision edge to stop bleeding are realized at the same time. The doctor does not need to perform subsequent sutures, which improves the operation efficiency and shortens the operation time.

2. The anastomotic mechanism is connected with the firing instrument through the swinging hinge to achieve lower surgical operations.

3. Use in the endoscopic environment, so that the patient's surgical wound is small.
