Description

Foreskin anastomat

Technical Field

The invention relates to the field of medical instruments, in particular to a foreskin anastomat.

Background

With the development of medical technology, medical anastomats are more and more widely applied. The foreskin anastomat is used as a common anastomat in the operation of the male urinary system, and plays a great promoting role in solving the problem of the overlong foreskin of the male genital organ.

Although the application method of the foreskin anastomat in the prior market is simple and greatly relieves the pain of a patient, the foreskin cutting mode is press-in type cutting, so that the patient with incomplete cutting inevitably occurs in the operation. For this type of patient, the doctor needs to re-trim with additional scissors; even some of the first physicians cut the foreskin by squeezing the handle multiple times. Because the foreskin has contractibility, the foreskin at the cut part can retract after the handle is released, the foreskin at the uncut part keeps a stretching state, and the beauty of the anastomotic stoma can be influenced by pressing and holding the handle for many times for cutting.

In view of this, how to provide a foreskin anastomat, which ensures that the complete cutting of the foreskin can be formed by pressing and holding the handle once, is the technical problem to be solved by the invention.

Optionally, in an embodiment of the present application, a positioning hole is formed in a side surface of the blade, and a third sliding groove is formed in the housing.

Preferably, in an embodiment of the present application, the hand wheel ring is disposed outside the front end of the housing and is fixedly connected to the blade positioning hole through the positioning block, and the third sliding groove provides an actuating path of the positioning block when the prepuce anastomat works. The tool bit can be driven to rotate by rotating the hand wheel. Therefore, the invention can rotate the cutter head when the prepuce is not completely cut in a press-in mode, so that the cutting edge slides relative to the prepuce to smoothly complete cutting, thereby improving the one-time complete cutting rate.

According to the technical scheme, the foreskin anastomat provided by the embodiment of the invention drives the blade to rotate by virtue of the hand wheel so as to provide sliding movement of the blade relative to the foreskin, so that the cutting efficiency is improved, and the condition of incomplete cutting at one time is improved.
