Prepuce anastomat

Abstract

The invention belongs to the technical field of surgical instruments and relates to a prepuce anastomat. The prepuce anastomat comprises a glans holder, a slide staple chamber, a body, a knife closing mechanism and a buffering compression mechanism. The body comprises a staple ejector and a circumcision knife, the staple ejector is positioned on the outer side of the front end of the body, and the circumcision knife is positioned on the inner side of the staple ejector and extends to the front of the staple ejector. The slide staple chamber with anastomosis staples mounted at the front end sleeves the staple ejector, and the buffering compression mechanism which pushes the slide staple chamber forwards is mounted between the slide staple chamber and the body. The glans holder for fixing tissues is provided with a knife abutting ring matched with the circumcision knife and staple anvils matched with the anastomosis staples in the slide staple chamber. By backward movement of the knife closing mechanism, the glans holder clings to the slide staple chamber, pushes the slide staple chamber to move backwards to get close to the circumcision knife, and finally pushes the slide staple chamber to make the staple ejector eject the anastomosis staples. The prepuce anastomat has advantages of simple structure and improvement of surgical quantity and surgical comfort.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a prepuce stapler. Background technique [0002] Circumcision is a common surgical operation. Surgical cutting is performed with a circumcision device, which can remove excess tissue at one time, with less bleeding, and can be sutured while cutting, which is convenient for postoperative recovery. [0003] CN102973311A discloses a circumcision device, which consists of a glans seat, a nail bin, a shell head, an apex, a blade, a return spring, a top cap, a connecting rod, a handle, an adjustment knob, a pull rod, and a glans seat connecting rod. When in use, put the glans into the glans seat, stretch the foreskin to cover the glans seat, then fix the stretched foreskin on the front end of the pull rod, put the rest of the circumcision device on the pull rod, tighten the adjustment knob, the external force Function handle, the handle pushes the top cap, acrosome and blade through the connec...

AI Technical Summary

Problems solved by technology

[0004] Yet this circumcision device has following shortcoming: 1. blade is assembled, and operation quality is affected by assembly precision, and human factor influence is big

2. Before cutting, there are no parts to pre-press and position the tissue elastically, and the knife is cut directly to make the tissue easy to shift during the cutting process

3. The push-type handle structure is used for cutting in the front and rear directions. The cutting action is large and it is easy to damage the tissue. The cutting process is a blind cut, and it is impossible to observe and grasp the progress of cutting and stapling. child

4. There is no structure for protecting the frenulum and quantitative resection. During the cutting process, the doctor can only rely on the doctor to tilt the stapler to protect the frenulum, which may cause too much or too little cutting of the frenulum.

5. Using ordinary nails with thinner nail beams, the effect of nail removal during tissue healing is not good enough
