Description

tissue closure staples

technical field

The invention belongs to the field of surgical staples, in particular to a tissue closure staple.

Background technique

Surgery is one of the conventional surgical treatments, and the popularization of laparoscopic surgery is an inevitable trend in the development of surgery now and in the future. Compared with open surgery, laparoscopic surgery has the following advantages: faster recovery after less trauma, less bleeding, and cosmetic effects on the abdominal wall. However, the condition brought about by the obvious advantages is that doctors need to complete more refined operations in a small space.

At present, the commonly used method of incision suture in endoscopic surgery is thread suture, but thread suture has the following three deficiencies: 1. If the puncture hole cannot be tightly and effectively sutured, the probability of postoperative incisional hernia complications is high, and at the same time, the risk of incision infection It will also be greatly improved; 2. For obese patients, the fat layer is very thick, and it is difficult to suture the peritoneum safely and effectively by the traditional method of suturing from the skin surface; The risk of accidental injury to the intestinal wall is high, and the operation of suturing and knotting under the laparoscope is very complicated and inconvenient. At the same time, the stitching action requires the surgeon to practice proficiently after a long period of practice. After the operation is completed, three people are required to cooperate in the suturing process to complete the suturing operation.

Patent No. 100556373C discloses a staple for endoscopic surgery. Barbs are made at one or both ends of the U-shaped nail. At the same time, the U-shaped nail is closed with anti-skid lines, the purpose of which is to prevent the U-shaped nail from being stuck in the clamped tissue. Under the action of the elastic recovery force, the phenomenon of slippage occurs. However, due to the fixed size of the U-shaped nails, the opening degree of the jaws of the surgical suturing forceps is greatly affected by the distance between the two ends of the U-shaped nails. The side tissue shrinks inward, and when the tissue at both ends of the incision is close to a certain degree, the incision is sutured with surgical forceps. This kind of operation is labor-intensive, and requires medical personnel to expend considerable effort to complete the shrinkage of the tissues on both sides of the incision. When suturing deeper tissue parts, manual operation is very inconvenient.

Contents of the invention

The present invention is made to solve the above problems, and aims to further reduce the difficulty of existing laparoscopic surgery suturing by providing a novel laparoscopic tissue closure nail.

In order to solve the above problems, the present invention adopts the following technical solutions:
