Description

A multi-head bifurcated surgical suturing device

technical field

The utility model relates to the technical field of medical instruments, in particular to a multi-head bifurcated surgical suturing device.

Background technique

In surgical operations, in some cases, medical personnel need purse-string sutures, or for irregular wounds to be sutured, and purse-string sutures are performed on organ stumps for firm ligation. Surgical sutures refer to surgical operations, or trauma During the treatment, the special threads used for ligation and hemostasis, suture hemostasis and tissue suture can generally be divided into two categories: absorbable thread and non-absorbable thread. Until the wound is healed, it is often necessary to use sutures of various sizes in a surgical operation to adapt to the needs of different tissues.

There are following defects in the existing suturing device in the prior art:

1) Existing sutures can only be used for suturing at one end. For the suturing of irregular wounds or purse string sutures, the single-end suture has low work efficiency and poor suturing effect.

2) According to the shape of the needle body, medical suture needles can be generally divided into two types: triangular needle and round needle. Although the triangular needle is sharp, its puncture force is strong, but the tissue cutting damage is large, easy to bleed, and the corresponding damage is also large, which affects wound healing. The cross-section of the conventional suture needle body is round. , the strength is slightly larger, and the needle rotation will appear. In addition, the use of round needles, changing the angle during suturing will cause the needle holder to suture unstable, and the needle handle is easy to slide along the clamping surface of the needle holder, which is easy to cause The inaccurate positions of the needle entry and exit during suturing lead to accidental injury to adjacent tissues and organs. At the same time, due to the lack of stability of the suture needle, the needle body is prone to twisting, even bending and breaking during operation, causing irreparable damage to the patient, especially Surgeons have to resort to the assistance of other surgical instruments in order to change the direction of the needle body when performing fine surgical operations in the deep part of the body cavity, and it is difficult to adjust the direction and fix the needle.

Chinese patent application: CN201822880U, publication date: 2011.05.11, discloses a surgical needle set with sutures of different diameters, including a needle and a suture. The suture needle has a first end and a second end opposite, and the first end of the suture needle is formed with a needle point. One end of the suture is connected to the second end of the sewing needle, and the suture has at least two diameters of different thicknesses, one end of the first diameter section is connected to the second end of the sewing needle, and one end of the second diameter section is connected to the second end of the sewing needle. The other end of a diameter segment.

Chinese patent application: CN108095784A, publication date: 2018.06.01, discloses a suture device for surgical skin, including a top cover, the top cover is provided with a lower handle shell, the top cover is closely connected with the handle shell, and the lower end of the top cover is provided with a storage The needle box and the needle storage box are closely connected with the top cover, and the lower end of the needle storage box is provided with a needle extraction port.

Chinese patent document: CN201743724U, publication date: 2011.02.16, discloses a surgical needle set that can adjust the radian of the needle, including a needle and a suture. The sewing needle is curved and has a front section and a back section connected to each other. The end of the front section away from the back section is formed with a needle point. The front section is made of high rigidity material and the back section is made of low rigidity material. One end of the suture is connected to the end of the rear section of the sewing needle away from the front section.
