Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings.

[0020] Such as figure 1 As shown, the laparoscopic stapler of the present invention comprises a sewing needle 1, a needle holder 2, a main rod 3, a handle 4, a locking nut 5, a rotating rod 6, and sutures 7, and the needle holder 2 is a rotating needle holder, and the sewing needle 1 is fixed on the rotating needle seat, the rotating needle seat is movably connected with the end of the rotating rod 6, the rotating rod 6 is stable in the inner cavity of the main rod 3, and the surfaces of the rotating needle seat and the end of the rotating rod 6 are provided with spiral bevel teeth ( Such as figure 2 As shown), the tail end of the main rod 3 is provided with a locking nut 5 that stabilizes the rotating rod 6 in the inner cavity of the main rod 3. By rotating the rotating rod 6, the needle seat 2 can be rotated and fixed on the seam on the bottom edge of the rotating ...

Abstract

The invention relates to a surgical instrument for treating the disease of belly, especially providing a laparoscope-stitching instrument, which can flexibly stitches in the belly surgery. The invention comprises: a stitching needle (1), a needle stand (2), a main rod (3), a handle (4), a locking nut (5), a rotary rod (6), and suture (7). Wherein, the needle stand (2) is the rotary needle stand on which the stitching needle is mounted; the ends of the rotary needle stand and the rotary rod (6) are in the movable connection of helical bevel tooth; and the rotary rod (6) is mounted in the inner cavity of main rod (3). Compared to present technology, the invention utilizes the structure that the stitching needle is mounted on the rotary needle stand, so the stitching needle can turn around in the range of 270 degrees for supplying the stitching needle to pass in and out the abdominal cavity flexibly, and stitch, knot in full directions of the human body when in the laparoscope surgery. In addition, the suture needed as common ones takes two times to pass in the front and back ends of stitching needle, so it can replace the ferrule technique in present laparoscope and reduce the cost of material.

Description

technical field [0001] The invention relates to a surgical instrument for treating abdominal diseases, in particular to a laparoscopic stapler which can suture flexibly in abdominal surgery. Background technique [0002] In the past two decades, various scientific and technological advances have further developed laparoscopic surgery, and laparoscopy with minimally invasive effects has played an important role in the diagnosis and treatment of abdominal diseases. For any laparoscopic operator, hemostasis may be the most important. The backwardness of laparoscopic suturing technology may be the only important factor for the slow development of laparoscopic surgery, and it is also an important reason for the high cost of laparoscopic surgery. Basic suturing skills are necessary in laparotomy, but the flexibility of suturing in abdominal surgery is mostly lost in laparoscopic surgery. In order to make up for the deficiencies of the existing technology, simple but more dangerou...
