Problems solved by technology

[0003] Based on this, it is necessary to provide a hemorrhoid stapler for the problem of high percussion force
[0005] The aforementioned hemorrhoidal stapler is equipped with an electric power structure that drives the closing mechanism and the firing mechanism to solve the problem of excessive pulling caused by the shaking of the arm during the excitation process caused by the large closing force, and avoids affecting the butt closure and success of the anastomotic stoma. Nail effect - incomplete or over-extrusion of the nails, thereby ensuring the effect of the operation

Abstract

The invention relates to a hemorrhoid stapler. The hemorrhoid stapler comprises a staple abutting seat and a shell and is characterized in that a staple bin, a staple pushing piece, a closing mechanism and a firing mechanism are assembled in the shell, the closing mechanism is used for driving the staple abutting seat to move relative to the shell to as to form a jaw between the staple abutting seat and the staple bin, the firing mechanism is used for driving the staple pushing piece to move towards the staple abutting seat so as to push out a suturing staple in the staple bin, the staple abutting seat is provided with a conical outer surface, the staple bin is provided with an inner cavity for accommodating tissue, the shell is provided with a plurality of pull wire holes corresponding tothe staple bin and communicated with the inner cavity, and the shell is further provided with an electric power structure for driving the closing mechanism and the firing mechanism to work. The hemorrhoid stapler has the advantages that the stapler is provided with the electric power structure for driving the closing mechanism and the firing mechanism to work, so that the problem of excessive pulling caused by arm shaking due to the fact that large closing force is used for firing, the butt joint closing degree and stapling effect-stapling incompleteness or excessive squeezing of a anastomotic stoma cannot be affected, and the surgery effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a hemorrhoid stapler. Background technique [0002] Existing hemorrhoid staplers mostly rely on manual disposable instruments. In surgical operations, doctors often need to rotate the knob at the end to close the proximal and distal tissues, and close the firing rod with both hands under reasonable tissue compression to complete the anastomosis. The firing process requires a huge firing force to complete the cutting and closure of the anastomotic stoma. Huge closing force brings excessive pulling due to arm shaking during excitation, which affects the butt closure of the anastomotic stoma and the effect of staple formation-incomplete or over-extrusion of the staples, resulting in potential leakage and irregular stenosis of the anastomotic stoma , Affect the effect of the operation and is not conducive to the postoperative recovery of the patient. At the same time, ...
