Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a stapler head and stapler for circumcision. Background Technology

[0002] In circumcision surgery in urology, doctors often use a foreskin stapler to perform the operation, which allows for simultaneous cutting and suturing. This method is convenient and efficient, effectively solving problems such as complex procedures, long operation time, excessive bleeding, pain, uneven incision, and postoperative hematoma and edema in circumcision surgery.

[0003] Currently, existing circumcision devices first insert the glans cover into the foreskin, and then tighten the glans cover with the tail nut to compress the foreskin. Finally, the handle is pulled to drive the staples from the pre-placed staple cartridge into the foreskin. After passing through the foreskin, the staples are blocked by the forming groove of the front staple plate, completing the anastomosis operation (i.e., the firing operation). At the same time, the ring blade removes the excess foreskin. However, because the glans cover is pre-inserted into the foreskin, medical staff cannot confirm the exact location of the tissues between the foreskin and glans (such as the sulcus, umbilical cord, etc.), nor can they determine the exact location of the glans. During the circumcision anastomosis procedure, misoperation may occur, potentially cutting into these tissue structures, which poses a significant risk to the surgery and affects its quality. Furthermore, during firing, the glans cover only fixes the foreskin and glans relative to the gun body, while the posterior penile tissue remains unfixed, further impacting surgical quality and increasing the difficulty of the procedure. Additionally, the glans cover and its binding are inserted into the firing chamber along with the tissues; the limited space within the chamber may prevent the accommodating of longer tissues, or may cause the tissues to shift relative to the glans cover during firing. Medical staff cannot observe or adjust accordingly, further affecting surgical quality. Moreover, the traditional circumcision stapler has a single-sized anastomosis head, which cannot meet the surgical requirements. Summary of the Invention

[0004] The purpose of this invention is to provide a circumcision stapler head and a circumcision stapler to solve the problems that existing circumcision staplers affect surgical quality and that the stapler head has a single size, which cannot meet surgical needs.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Firstly, according to embodiments of the present invention, such as Figure 1 and Figure 2 As shown, a circumcision stapler head is provided, which is applied to the circumcision stapler. It includes a foreskin fixing cover 1, which is a hollow cylindrical structure. One end of the foreskin fixing cover 1 has a binding part 11 for fixing the foreskin, and a binding ring groove 12 is provided on the binding part 11. The other end of the foreskin fixing cover 1 has a first adjustable connecting part, and the front end of the gun body 2 of the circumcision stapler has a second adjustable connecting part. The first adjustable connecting part and the second adjustable connecting part cooperate to form a detachable connection.

[0032] In this embodiment, the foreskin fixation cover 1 is placed on the patient's penis. The surgeon retracts the foreskin, wraps the retracted foreskin around the binding part 11, and then binds and fixes the retracted foreskin at the binding ring groove 12. In this way, the surgeon can directly observe the tissues between the foreskin and the glans (such as the sulcus, umbilical cord, etc.) directly with 360° without blind spots, observe the specific position of the glans, and fix the posterior penile tissue, reducing the difficulty of the surgical operation and improving the accuracy of the surgeon's cutting. At the same time, the foreskin fixation cover 1 and the cavity of the foreskin stapler are detachably connected. Therefore, the surgeon can select a suitable foreskin fixation cover 1 according to the size of different patients' penises, improving the applicability of the foreskin stapler.

[0033] In the above embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the first adjustable connection part includes a raised key 13, on which a threaded hole 131 and a first channel 132 communicating with the threaded hole 131 are provided; the second adjustable connection part includes an extension rod 21, a screw 23, and a die-cast nut 22 for threaded connection with the screw 23; the die-cast nut 22 is connected to the first end of the extension rod 21, and the second end of the extension rod 21 is provided with a groove 211 adapted to the raised key 13, the raised key 13 can slide along the groove 211, the first end of the extension rod 21 is the end of the extension rod 21 connected to the gun body 2, and the second end of the extension rod 21 is the end of the extension rod 21 away from the gun body 2; a second channel 212 is provided on the inner side of the extension rod 21, and the second channel 212 communicates with the threaded hole of the die-cast nut 22; the screw 23 can pass through the die-cast nut 22, the second channel 212 and the first channel 132 and then connect to the threaded hole 131 of the raised key 13.

[0034] The number of raised keys 13 and die-cast nuts 22 can be multiple, and the specific number is not limited in this embodiment. The raised keys 13 and die-cast nuts 22 are evenly distributed along the outer peripheral walls of the cover fixing cover 1 and the gun body 2, respectively. The extension rod 21 is integrally formed with the gun body 2 to enhance the stability and reliability of the connection between the extension rod 21 and the gun body 2.

[0035] In this embodiment, the protruding key 13 of the foreskin fixing cover 1 is inserted into the sliding groove 211 of the extension rod 21. Then, the screw 23, threadedly connected to the die-cast nut 22, passes through the second channel 212 and the first channel 132 and connects to the threaded hole 131 of the protruding key 13. The screw 23 is then tightened, causing the foreskin fixing cover 1 to gradually move closer to the gun body 2, thereby compressing the tissue to be cut between the foreskin fixing cover 1 and the gun body 2. The second channel 212 and the first channel 132 limit the movement of the screw 23, reducing shaking during tightening and improving patient comfort. Furthermore, once the die-cast nut 22 is connected to the threaded hole 131 of the protruding key 13 via the screw 23, circumferential positioning between the foreskin fixing cover 1 and the gun body 2 is achieved, ensuring no relative circumferential movement occurs between them.

[0036] In the above embodiment, the outer side of the extension rod 21 is provided with a pre-tightening scale. The operator can judge whether the optimal pre-tightening has been reached according to the pre-tightening scale on the extension rod 21, so as to facilitate the operator's operation. When the pre-tightening scale position is reached, it is locked by the pin assembly or spring set screw to further ensure the stability of the connection.

[0037] Secondly, according to embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a circumcision stapler is provided, including a gun body 2, a ring blade body 3, a ring blade 4, a glans cover 7, and the aforementioned stapler head; the ring blade body 3 is located inside the gun body 2 and is connected to the gun body 2 via a pushing device; the circumferential inner edge of the ring blade body 3 is connected to the ring blade 4 by inlay casting or die casting; the center of the ring blade body 3 is detachably connected to the tail of the glans cover 7; the ring blade 4 is located outside the glans cover 7, and the end face of the annular opening of the glans cover 7 is higher than the end face of the ring blade 4.

[0038] In this embodiment, the foreskin fixing cover 1 is first placed on the patient's penis. The surgeon retracts the foreskin, wrapping it around the binding part 11. Then, the retracted foreskin is bound and fixed at the binding ring groove 12. The protruding key 13 of the foreskin fixing cover 1 is inserted into the sliding groove 211 of the extension rod 21. The screw 23, which is threaded to the die-cast nut 22, passes through the second channel 212 and the first channel 132 and connects to the threaded hole 131 of the protruding key 13. Then, the screw 23 is screwed on, causing the foreskin fixing cover 1 to gradually move closer to the gun body 2. Referring to the pre-tightening scale on the outside of the extension rod 21, the tissue to be cut is pressed tightly against the foreskin fixing cover. The appropriate position between the fixed cover 1 and the gun body 2 is determined, and the glans is placed and fixed inside the glans cover 7. Then, the ring blade body 3 is moved along the slide inside the gun body 2 towards the tissue to be cut by triggering the pushing device. The ring blade 4 is used to cut the tissue to be cut. The ring blade body 3 is provided with a staple cartridge surrounding the outside of the ring blade 4. The staple cartridge contains anastomotic staples. The gun body 2 is provided with a movable handle to push out the anastomotic staples. The movable handle can push the anastomotic staples in the staple cartridge at the front end through the side of the ring cutter by the connector set in the ring blade body 3, and then suture the cut site directly, completing the cutting and suturing surgical process simultaneously.

[0039] The pushing device can be any existing pushing device, and this embodiment is not limited to it. An annular groove is provided on the outer edge of the annular blade body 3 to clamp and fix the annular blade 4. Of course, the annular blade 4 and the annular blade body 3 can also be connected by other methods such as die casting. The tail of the glans cover 7 is threadedly connected to the annular blade body 3 to achieve a detachable connection between the glans cover 7 and the annular blade body 3, facilitating the replacement of the glans cover 7.

[0040] Furthermore, a reset mechanism for resetting can also be provided on the ring cutter body 3, such as a reset spring, a threaded drive reset device, etc. The reset mechanism can be used to reset the ring cutter body 3 in preparation for the next cutting and sewing operation, which is convenient to use.

[0041] In the above embodiments, such as Figure 3 and Figure 4As shown, a nail outlet positioning ring 5 is also installed at the front end of the gun body 2. The outer diameter of the ring blade 4 is smaller than the inner diameter of the nail outlet positioning ring 5. A nail outlet hole 51 is provided on the circumference of the nail outlet positioning ring 5.

[0042] Specifically, the lower end face of the nail outlet positioning ring 5 is provided with a stop step, which is bonded to the front end of the gun body 2 through the stop step, and the outer diameter of the ring blade 4 is smaller than the inner diameter of the nail outlet positioning ring 5, so that the ring blade 4 can reliably extend to cut the tissue.

[0043] In the above embodiments, such as Figure 3 and Figure 4 As shown, a staple rubber ring 6 is also installed on the staple outlet positioning ring 5, and the staple rubber ring 6 covers the staple outlet hole 51. The staple rubber ring 6 and the upper end surface of the staple outlet positioning ring 5 are on the same plane. By using the staple rubber ring 6 to block the staple outlet hole 51, the staple can be prevented from falling out from the staple outlet.

[0044] In the above embodiments, such as Figure 5 and Figure 6 As shown, the upper end face of the nail outlet positioning ring 5 is provided with a first insertion part, and the lower end face of the matching nail rubber ring 6 is provided with a second insertion part that can be inserted and cooperate with the first insertion part; the connecting line between the two adjacent first insertion parts and the center of the nail outlet positioning ring 5 forms a 90° angle; after the matching nail rubber ring 6 and the nail outlet positioning ring 5 are reliably inserted, the end face of the matching nail rubber ring 6 and the end face of the nail outlet positioning ring 5 remain on the same horizontal plane.

[0045] The first insertion part can be a slot 52, and the second insertion part can be a protrusion adapted to the slot 52, or the first insertion part can be a protrusion and the second insertion part can be a slot 52 adapted to the protrusion. Of course, the first and second insertion parts can also use existing insertion components, and this embodiment is not limited. Furthermore, the connecting line between two adjacent first insertion parts and the center of the nail outlet positioning ring 5 forms a 90° angle, which can realize the all-round connection between the nail outlet positioning ring 5 and the matching nail rubber ring 6, improving the stability and reliability of the connection.

[0046] In the above embodiments, such as Figure 3 and Figure 4 As shown, a ring-shaped protective cover 8 is fastened to the front end of the cavity, and the staple rubber ring 6 is located inside the protective cover 8. The protective cover 8 can prevent the staple rubber ring 6 from falling off.

[0047] In the above embodiments, such as Figure 3 and Figure 4 As shown, the foreskin retaining cover 1 of the anastomosis head is equipped with a pad ring 9, which is interference-fitted with the foreskin retaining cover 1. When the ring cutter 4 is firing, the cutting edge of the ring cutter 4 is precisely aligned with the middle of the pad ring 9, preventing damage to the cutter head and providing a buffering effect.

[0048] This invention provides a foreskin stapler head and a foreskin stapler. The foreskin fixing cover 1 is placed on the patient's penis. The surgeon everts the foreskin, wrapping the everted foreskin around the binding part 11, and then binding and fixing the everted foreskin at the binding ring groove 12. In this way, the surgeon can directly observe the tissues between the foreskin and glans (such as the sulcus, umbilical cord, etc.) without blind spots, observe the specific position of the glans, and fix the posterior penile tissue, reducing the difficulty of the surgical operation and improving the accuracy of the surgeon's cutting. At the same time, the foreskin fixing cover 1 and the cavity of the foreskin stapler are detachably connected. Therefore, the surgeon can select a suitable foreskin fixing cover 1 according to the size of different patients' penises, improving the applicability of the foreskin stapler.
