Description

Knife anvil ring special for circumcision stitching instrument

Technical Field

The utility model relates to a medical equipment field for the foreskin operation, in particular to a dedicated novel sword hammering block ring on circumcision stitching instrument.

Background

Prepuce overlength and phimosis are common phenomena in men, and the prepuce overlength can cause sensitive glans epidermis to cause premature ejaculation, thereby causing uncoordinated sexual life. Is also the most common reason influencing the health of male and female genital tracts, the redundant prepuce is easy to store dirt, so the inflammation is caused, even the glans cancer and the cervical cancer are caused, the normal couple life is influenced, the sperm quality is reduced, and the prenatal and postnatal care is influenced. In order to solve the problem that part of men suffer from the redundant prepuce, prepuce operation is initiated.

The circumcision stitching instrument can regularly cut redundant foreskin at one time, and simultaneously stitch the circumcision operation opening, for example, a circumcision stitching instrument disclosed by the patent application No. 201610537384X, an improved circumcision stitching instrument disclosed by the application No. 2017100860459 and the like can well finish circumcision stitching operation, the glans penis seat in the two instruments comprises a glans penis cap and a pull rod, a knife anvil ring groove is arranged between the glans penis cap and the annular nail resisting seat, the connecting structure between the glans penis cap and the annular nail resisting seat completely depends on a groove bottom plate of the knife anvil ring groove, the connecting corner position between the outer edge of the glans penis cap and the groove bottom plate can cause the outer corner of a stitching nail to be reduced due to the flaring chamfer angle of the edge of the glans penis, the connecting thickness between the glans penis cap and the groove bottom plate is reduced, and the annular nail resisting seat needs to bear pushing pressure, the knife anvil ring groove is also subjected to the axial cutting thrust of the ring cutter, so that a corner connecting part between the bottom plate of the knife anvil ring groove and the outer edge of the glans penis cap can be subjected to very large stamping force, and the cutting tool is easy to break and damage during working and is not beneficial to application of the glans penis base. And the sword hammering block ring that matches and use in the sword hammering block annular of this kind of traditional structure also is the ring that the cross section becomes the rectangle, works as the improvement the inner structure of the sword hammering block annular of glans seat makes the connection structure between the tank bottom plate of sword hammering block annular and the glans penis cap obtain strengthening the back, and sword hammering block ring also needs supporting renewal, and new sword hammering block ring both need can provide the punching through after accomplishing and feel, still need conveniently withdraw from the blade, this does the utility model discloses the main technical problem who solves will be researched.

SUMMERY OF THE UTILITY MODEL

The main object of the present invention is to solve the above mentioned technical problem.

In order to achieve the above object, the utility model provides a dedicated sword hammering block ring on circumcision stitching instrument, its detachable inlays to be put in a hammering block annular, and it is including being the flaky anvil plate of ring, be equipped with the outer ring foot of a tube-shape corresponding to radial outside edge axial projection on the downside terminal surface of anvil plate, be equipped with the inner ring foot of a tube-shape corresponding to radial inside edge axial projection on the downside terminal surface of anvil plate, the inner ring foot is coaxial with the outer ring foot, anvil plate and outer ring foot and inner ring foot integrated into one piece, anvil plate and outer ring foot and inner ring foot constitute a transversal concave ring shaped structure of personally submitting.
