Other parts of the circumcision stitching instrument can be used for the second time, and the technical problem that the traditional circumcision instrument can not be used for the second time is solved. The technical effects of saving resources and reducing cost are achieved.

As shown in fig. 2 and 3, the staple pusher 3 includes: a working ring 301 connecting the ring cutter 5 and the ejector pin sheet, a connecting part 302 extending into the pushing device 6, and a transition part 303 connecting the working ring 301 and the connecting part. The working ring 301 is detachably connected with the transition part 303 in a positioning manner, and the other end of the transition part 303 is integrally formed with the connecting part 302.

The working ring 301 is detachably connected with the transition part 303 in a positioning way. Specifically, the method comprises the following steps: the connecting positions of the working ring 301 and the transition part 303 are set as two positions, which are respectively: a threaded connection 31 and a snap connection 32. Further, the threaded connection 31 is: one end of the working ring 301 close to the transition part 303 is an external thread ring with the inner diameter smaller than that of the transition part 303, and the working ring 301 is fixed at the end of the transition part 303 through the matching connection of the external thread ring and the internal thread of the inner wall of the end of the transition part 303. The snap connection 32 is: the end of the working ring 301 at the threaded connection is provided with a second snap structure 33 (preferably a snap with good elasticity and high strength), and the inner wall of the through transition part 303 is provided with a second positioning hole 34. During the threaded connection rotation process of the working ring 301 and the transition part 303, the second buckle structure 33 rotates to enter the positioning hole 34, namely, the threaded connection is completed, so that an installer can conveniently know whether the mounting position is accurate, and the stability and the reliability of the circumcision stitching instrument are improved. Preferably, the second positioning hole 34 is a through hole, so as to facilitate the detachment of the second fastening structure 33.

In a preferred embodiment, the first positioning hole 23 and the second positioning hole 34 are coaxial. When the working ring 301 needs to be disassembled, the snap connection portion 32 can be ejected out of the second positioning hole 34 by inserting a tool into the second positioning hole 34 through the first positioning hole 23, so that the separation between the working ring 302 and the transition portion 303 is satisfied.

In order to realize the circumcision effect, a ring cutter 5 is connected to one end of the working ring 301, which is far away from the connecting part 302; the other end of the connecting part 302 is connected with the pushing device 6, so that the pushing device 6 pushes the nail pushing part 3 to slide, and the cutting effect on the foreskin is realized.

In order to realize the detachable effect of the glans penis cover 1, the effect of reducing the treatment cost can be achieved by replacing the components. As shown in fig. 2 and 5, the tortoise cover 1 includes: a cover body 101 for positioning and fixing the glans of the patient and a connecting rod 102 for connecting and fixing the glans. The tail end of the cover body 101 is detachably connected (may be in threaded fixed connection) with the connecting rod 102, the connecting rod 102 is fixedly connected with the pushing device 6, and the front end of the cover body 101 is arranged at the front end of the replacing ring 201. The supporting effect of the cover body 101 on the sewing nail 8 and the cushion effect on the circular cutting knife 5 are achieved, and the sewing effect and the circular cutting effect are guaranteed.

As shown in fig. 5, in order to improve the stability of the connection between cover 101 and link 102, a support member 103 is fixedly connected to link 102, and support member 103 is in seamless contact with the end of cover 101. When the glans penis is sleeved and fixed by the cover body 101 in the circumcision stitching instrument, the connecting rod 102 applies pressure to the cover body 101, and the arrangement of the supporting piece 103 can enable the axial force at the joint of the cover body 101 and the connecting rod 102 to be uniformly distributed, so that the service life of the connecting rod 102 is prolonged. Meanwhile, the stability of the joint is enhanced by the support piece 103, and the cutting and sewing effects are prevented from being influenced by looseness of the joint.

Further, as shown in fig. 2 and 3, in order to avoid the situation that the pushing force of the nail pushing member 3 on the suturing nail 8 is too large during the circumcision and suturing of the foreskin, the suturing nail 8 has too large suturing pressure on the suturing wound, and the tissue of the suturing wound is damaged. For example, the pressure may be too great, pressing staple 8 directly into the tissue, failing to effect the stapling of staple 8, and causing secondary injury to the patient. The front end of the nail bin part 4 is clamped with a silica gel ring 7, and the silica gel ring 7 is arranged at a nail outlet of the nail bin part 4 provided with a suturing nail 8. In the suturing process, the suturing nail 8 firstly penetrates through the silica gel ring 7, and the rear end of the suturing nail 8 is guaranteed to be supported on the surface of the silica gel ring 7 through the padding and protection effects of the silica gel ring 7, so that the tissues at the wound of the suturing part are protected.

As shown in fig. 1 to 6, in order to further support the sewing nail 8, a backing knife of the ring cutter 5 may be used. The edge of the cover body 101 is of a turnover structure, and a turnover inner cavity of the turnover structure is of a step-shaped structure. As shown in fig. 4 and 6, the stepped structure includes: a recessed ring 9 that fits the ring cutter 5 and a stepped ring 10 that fits the staples 8. In order to ensure the cutting depth of the circular cutter 5, the depth of the groove ring 9 is larger than that of the step ring 10, so that complete cutting of the foreskin is ensured, and the wound for cutting the foreskin can be sutured.

Of course, the step ring 10 is provided outside the edge of the notch ring 9, since the suture is close to the root of the penis with respect to the circumcision. The cover body 101 with the edge in the turnover structure can facilitate the insertion of the foreskin, ensure the smooth cutting of the foreskin and facilitate the cutting and sewing processes of the foreskin.

In order to improve the stitching strength of the stitching nail 8, the tip part of the stitching nail 8 is ensured to be bent and fixed on a stitching wound. As shown in fig. 1 and 6, guide diagonal grooves 11 are provided at the bottom of the stepped ring 10 (at both ends of one staple, inclined toward the middle with respect to each other) to guide and bend the staples 8 (similar to the backing plate function of a stapler). A cutter backing ring 12 is arranged inside the groove ring 9, so that the ring cutter 5 cuts into the cutter backing ring 12. The arrangement of the cutter backing ring 12 enables the circumcision knife 5 to effectively cut the foreskin when cutting the foreskin, and avoids the secondary damage to the patient caused by the incomplete excision of the foreskin tissue.

Specifically, as shown in fig. 3 and 4, the shim ring 12 includes: the ring-shaped cutting knife comprises an inner wall 121, an outer wall 122 and a knife backing plate 123, wherein the outer part of the ring-shaped inner wall 121 is concentrically provided with the ring-shaped outer wall 122, the inner wall 121 and the outer wall 122 are connected through the knife backing plate 123, a separation cavity 13 is defined among the inner wall 121, the outer wall 122 and the knife backing plate 123, and the cutting direction of the ring-shaped cutting knife 5 extends into the separation cavity 13. The separating cavity 13 defined by the inner wall 121 and the outer wall 122 of the cutter backing ring 11 enables the ring cutter 5 to cut into the cutter backing plate 123 and enter the separating cavity 13, and the cutter backing plate 123 can be used as a medium to connect the inner wall 121 and the outer wall 122 and can also be used as a chopping block for cutting the foreskin by the ring cutter 5, so that the effect of completely cutting the foreskin is achieved, and the problem that the foreskin tissue enters the groove ring 9 and cannot be completely cut off to cause secondary injury to a patient is avoided.

In order to increase the pushing action of the circumcision stitching instrument for replacing the ring cutter and stitching the nail cabin, the pushing device 6 comprises: a handle 601 for holding, a support sleeve 602 for supporting and fixing, an adjusting knob 603 for adjusting the position of the tortoise cover 1, and a sliding sleeve 604 for pushing the nail pushing piece 3. The support sleeve 602 is clamped with the tail part of the body part of the nail bin sleeve 2, the adjusting knob 603 is fixedly connected with the tail end of the support sleeve 602, and the connecting rod 102 of the glans penis cover 1 is in threaded connection with the adjusting knob 603. By rotating the adjusting knob 603, the stretching distance of the balanus cover 1 can be controlled, and the prepuce cutting distance of the patient is fixed and limited before the cutting is facilitated.

A sliding groove is formed in the position along the supporting sleeve 602, the sliding sleeve 604 is connected inside the sliding groove in a sliding mode, and the inner wall of the sliding sleeve is connected with the nail pushing piece 3 in a buckling mode, so that the sliding sleeve 604 can slide along the sliding groove to push the nail pushing piece 3 to slide. The handle 601 is connected with the outer wall of the sliding sleeve 604. The handle 601 includes: the front end of the clamping arm 6011 is hinged with the outer wall of the nail bin sleeve 2, and the middle part of the clamping arm 6011 is hinged with the sliding sleeve 604 through the connecting arm 6012. When the handle 601 is operated, the sliding sleeve 604 can be driven to move, so that the nail pushing piece 3 is controlled to slide, and circular cutting and sewing are realized.

In order to facilitate the operation and control of the medical staff, two handles 601 are preferably symmetrically arranged, so that the clamping arms 6011 of the two handles 601 are drawn together inwards, and the pushing force is transmitted through the hinged connecting arm 6012 to push the sliding sleeve 604 to slide, thereby facilitating the operation and control of the medical staff.

Through the arrangement of the handle 601, the sliding sleeve 604 and the nail pushing piece 3, a worker can control the sliding sleeve 604 to slide along the sliding groove by clamping and loosening the symmetrical handle 601. Because the inner wall of the sliding sleeve 604 is in snap connection with the nail pushing piece 3 (the relative position is fixed), the sliding sleeve 604 drives the nail pushing piece 3 to move when moving, thereby achieving the effect of conveniently controlling the circular cutting and suturing processes.

In order to ensure that the handle 601 and the sliding sleeve 604 can be automatically reset after the work is finished. An annular step is arranged at the tail end of the nail bin sleeve 2, a compression spring 14 is arranged inside the annular step, and the other end of the compression spring 14 is connected with the sliding sleeve 604 in a supporting mode. When cutting and suturing, the compression spring 14 is compressed by the sliding sleeve 604; after cutting and suturing are finished, the compression spring 14 rebounds to push the sliding sleeve 604 to slide, and the connecting arm 6012 drives the handle 601 to complete the resetting action. Ensures that the circumcision knife 5 is separated from foreskin tissues and the whole circumcision knife stitching instrument is in an open state.

In order to realize the connection between the sliding sleeve 604 and the nail-pushing piece 3, the inner wall of the sliding sleeve 604 is a stepped hole, the inner diameter of the end of the sliding sleeve 604 far away from the adjusting knob 603 is smaller than that of the end close to the adjusting knob 603, and the stepped hole is clamped with the connecting part 302 of the nail-pushing piece 3. The arrangement of the stepped hole enables the connecting part 302 of the nail pushing part 3 to be clamped by the lower half part of the stepped hole when being inserted into the sliding sleeve 604, so that the quick assembly between the nail pushing part 3 and the sliding sleeve 604 is realized. Further, when the pushing device 6 is used for pushing the sliding sleeve 604, the upper half part of the stepped hole can bear the pushing force of the sliding sleeve 604 for pushing the nail pushing piece 3, so that the pushing effect on the nail pushing piece 3 is ensured.

In order to ensure the service life of the product, particularly long-term recycling, and high-intensity disinfection treatment is required after the product is used. Preferably, the pushing device 6 is a metal material.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.
