Endoscopic cutting stapler

Abstract

The invention discloses an endoscopic cutting stapler, comprising a stapling functional member, a connecting rod and a trigger handle. The stapling functional member comprises a staple magazine, a staple holder, an I-shaped beam member and a blade; one face, facing the staple holder, of the staple magazine is a curved face which enables staples to close and staple tissues when the staple magazine and the staple holder are closed; a plurality of rows of staples are arranged in the staple magazine, and the staples in accordance with the curved face of a first contact face are arranged in a curvilinear form; a push face, used for contacting holding blocks and pushing the same, of the I-shaped beam member is a curved face the same as the first contact face in shape. The contact faces of the staple holder and the staple magazine are modified into arc faces or bent faces (curved faces), overall diameter of the stapling functional member can be reduced at the premise of not reducing the width of tissues contained by the contact faces and ensuring closing effect of stapling, and thus, operations are made coherent and direct, surgical injury is reduced and operation results are improved.

Description

technical field [0001] The invention relates to a stapler, in particular to a laparoscopic cutting stapler, which belongs to the field of medical instruments. Background technique [0002] In the surgical operation of medical science, minimally invasive surgery is becoming more and more widely used for its small trauma, fast healing and good effect, so the stapler that can be used under the endoscope is essential. [0003] Endoscopic cutting staplers are usually composed of stapling functional parts, connecting rods, activation handles and other components. During the operation, make several small wounds on the abdominal wall or chest wall, insert the puncture device, insert the anastomotic functional parts from the puncture device, and operate the activation handle from the outside of the body after reaching the selected position, so as to achieve rapid and effective cutting and suturing of tissues role. [0004] Such as Figure 1 to Figure 3 As shown, the anastomotic fun...

AI Technical Summary

Problems solved by technology

Therefore, the existing laparoscopic cutting stapler cannot be directly inserted from the observation hole or the operation hole of the puncture device. The current method is to take out one of the puncture devices and re-puncture a puncture device with a diameter of 15 mm operation hole. The operation can only be continued by passing the anastomotic function part of the laparoscopic cutting stapler through the operation hole with a diameter of 15 mm

The dangers of such an operation are: first, the operation is not coherent enough, and even loses the observed and adjusted operation field.

Second, the operation time is prolonged

Third, the patient is traumatized

Fourth, it needs to go through the process of deflation-replacing the puncture device-reinflation, which is cumbersome to operate and increases the chance of potential damage
