For cutting by the pad ring cutter and forming the suturing nails, the front end of the cover body 11 is arranged at the front end part of the nail bin sleeve 2 and plays a role of the pad ring cutter and the suturing nails.

In order to facilitate the installation and fixation of the nail bin component 4, the process of installation and fixation is reduced, and the production and manufacturing cost of the whole circumcision stitching instrument is reduced. A nail bin hole 21 is formed in the position, close to the front end of the nail bin sleeve 2, of the nail bin piece 4, a buckle protrusion 41 is arranged on the outer wall of the nail bin piece 4, the buckle protrusion 41 is fixedly connected into the nail bin hole 21 in a buckle mode, the nail bin piece 4 is connected to the front end portion of the nail bin sleeve 2, and a suture nail groove 42 is formed in the nail bin piece 4. Namely: the stable fixed connection of the nail bin part 4 is ensured through the connection mode between the buckle bulge 41 and the nail bin hole 21, especially the connection mode between the buckle bulge 41 and the nail bin hole 21, the connection mode is simple, the labor intensity of workers is reduced, high-cost equipment such as ultrasonic welding is avoided, and the production and manufacturing cost is further reduced.

In order to realize the fixed connection and the pushing action on the ring-cutting knife 5 and the pushing action on the suturing nails in the nail bin component 4, the cutting and the wound suturing actions of the foreskin are further realized. The nail pushing piece 3 is arranged in the nail bin sleeve 2, the nail pushing piece 31 is arranged at the front end of the nail pushing piece 3, the nail pushing piece 31 is suitable for the position and size of the sewing nail groove 42, the nail pushing piece 31 extends into the sewing nail groove 42, the sewing nails are pushed, and then the sewing effect is achieved. A clamping groove 32 is formed in the inner position of the nail pushing piece 31 at the front end of the nail pushing piece 31, and the ring cutting knife 5 is clamped in the clamping groove 32. Similarly, the sliding of the ring cutter 5 is realized by the pushing action of the nail pushing piece 31, and then the cutting action of the foreskin is realized. Because the ring cutter 5 is also clamped with the nail pushing piece 31, the installation and the replacement of the ring cutter 5 can be conveniently realized, and the production and the manufacturing cost of the whole circumcision stitching instrument are reduced. Particularly, the convenient replacement of the ring cutter can be met, the ring cutter can be replaced at any time when the problem is solved, and the waste of the whole circumcision stitching instrument is avoided.

Of course, in order to ensure a power source for the staple pusher 3. The other end of the nail pushing piece 3 is connected with the pushing device 6, so that the pushing device 6 pushes the nail pushing piece 3 to slide, and the suturing effect of suturing nails and the circular cutting effect of the circular cutting knife 5 are realized.

In order to further conveniently realize the clamping action of the ring cutter 5. A clamping hole 33 is formed through the nail pushing piece 3, the axis of the clamping hole 33 penetrates through the clamping groove 32, the ring cutting knife 5 extends into the clamping groove 32, a clamping buckle 51 is formed at the tail end of the ring cutting knife 5, and the clamping buckle 51 is buckled into the clamping hole 33 for fixing. Through the cooperation connected mode of joint knot 51 with joint hole 33, satisfied convenient effect of connecting to ring cutter 5. The defects that in the prior art, the connecting modes such as ultrasonic welding or other welding are complex, and the installation cost of the ring cutter 5 is increased are overcome.

For the convenience of processing the snap fastener 51 on the ring cutter 5, preferably, the snap fastener 51 on the tail of the ring cutter 5 is a notch barb. The notch barb mode has the advantages of simple processing and low processing cost, and can meet the requirement of clamping conveniently. The damage to the cutting edge of the ring cutter 5 in the process of processing the clamping buckle 51 can be avoided, the yield of the ring cutter 5 is improved, and the production and manufacturing cost of the whole product is reduced.

In order to guarantee the joint intensity of incision barb, this incision barb is keeping away from the one end incision of girdling sword afterbody, and the trilateral quilt of incision barb is cut promptly, and only the one end that is close to the afterbody is 5 integrative with the girdling sword, guarantees 5 joint intensity with the girdling sword. Of course, because the ring-shaped cutter 5 is of an annular structure, the forming of the notch barbs is ensured in order to facilitate the construction of the processing technology. The incision barb extends toward the center of the ring cutter.

Of course, in order to ensure the fixing strength of the ring cutter 5, the ring cutter is prevented from shaking. The width of the notch barb is adapted to the diameter of the snap hole 33. The snap-in holes 33 can be designed to be square structures, and the width of the square structures is the same as that of the notch barbs.

In order to stably fix the nail bin component 4, especially to ensure the position matching between the nail pushing plate and the nail bin component 4, the installation precision of the nail bin component 4 is ensured. The nail bin hole 21 is a square hole, and the width of the square hole is the same as that of the buckling protrusion 41. Namely: the accurate positioning of the position of the nail bin part 4 is met, and the use requirement of the circumcision stitching instrument is guaranteed.

In order to conveniently realize clamping connection, the matched connection between the nail bin sleeve 2 and the nail bin sleeve is ensured. The catching projection 41 includes: a buckling rod 411 for connecting and extending, and a buckling head 412 for connecting and acting with the nail bin hole 21 of the nail bin sleeve 2. The snap head 412 is integrally formed with the magazine 4 by means of a snap rod 411.

In order to ensure the limiting and connecting strength, the connection stability of the nail bin part 4 is further realized. Four snap protrusions 41 are uniformly arranged along the annular cartridge 4.

Preferably, the circumcision stitching instrument has a protection function when not in use, and particularly prevents stitching nails from extending out or a girdling knife from extending out to scratch medical personnel. And the girdling knife or the suturing nail is extended out, the suturing nail needs to be reinstalled, and the cutting between the girdling knife and the glans penis cover causes damage to the girdling knife and influences the use of the circumcision suturing device. The circumcision stitching instrument is characterized in that a protective cover 8 is arranged between the nail bin 4 and the cover body 11 of the glans penis cover 1, and the stitching nail and the cutting knife can not extend out under the shielding effect of the protective cover 8, so that the use safety is ensured.

In order to guarantee the pushing action, the pushing means 6 comprise: a handle 61 for holding, a support sleeve 62 for fixing and supporting connection, an adjusting knob 63 for connecting with the glans 1, and a sliding sleeve 64 for connecting with the nail-pushing piece 3.
