Description

Replaceable knife anvil structure for prepuce cutting stitching instrument

Technical Field

The utility model relates to a circumcision stitching instrument is with can replacing sword hammering block structure.

Background

The existing circumcision cutter uses an anvil which is mostly an annular rubber anvil, and in the circumcision process, a cutting knife cuts off the circumcision and the anvil together so as to ensure that the wrapping sheet is completely cut off at one time. The knife anvil is a disposable consumable product, and the existing knife anvil needs to be firmly embedded into the groove at the bottom of the tortoise head cover so as to prevent the knife anvil from being displaced due to smaller size during cutting. But this also results in the cutting anvil becoming lodged in the recess in the bottom of the glans penis after cutting is complete and not easily removed.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a circumcision stitching instrument is with can replacing sword hammering block structure, aim at solving above-mentioned problem.

In order to achieve the purpose, the technical scheme of the utility model is to design a replaceable knife anvil structure for a foreskin cutting stitching instrument, which comprises a tortoise head cover and a knife anvil; the knife anvil comprises a knife anvil body, a knife anvil extension part and a jack of the knife anvil extension part; the knife anvil main body is in a circular ring sheet shape; the extending part of the knife anvil is two bilaterally symmetrical protruding sheets which are respectively positioned at the left side and the right side of the knife anvil main body; the knife anvil extension part is provided with a jack of the knife anvil extension part; two strip-shaped grooves which are bilaterally symmetrical and are used for embedding the extending part of the knife anvil are arranged at the protruding part of the edge of the bottom of the balanus cover; the strip-shaped groove is divided into a left groove, a right groove, a left groove and a right groove, the bottom edge of the glans penis cover between the left groove and the right groove is protruded, and the bottom edge of the glans penis cover between the left groove and the right groove is protruded to penetrate through the insertion hole of the extending part of the knife anvil.

The utility model has the advantages and the beneficial effects that: 1. the knife anvil can be firmly fixed in the groove at the bottom of the balanus cover, and the knife anvil is not easy to deviate when being cut due to the fixing effect of the extension part of the knife anvil on the bulge at the bottom edge of the balanus cover; 2. after the cutting of the knife anvil is finished, the extending part of the knife anvil and the knife anvil part connected with the extending part of the knife anvil can be taken down firstly, and then the cut knife anvil ring part in the groove at the bottom of the tortoise head cover can be easily poured out of the groove.
