Description

Technical Field

[0001] This invention belongs to the field of circumcision device technology, specifically a circumcision stapler that integrates cutting and suturing. Technical Background A circumcision stapler is a medical device used in circumcision surgery, primarily for the surgical treatment of patients with phimosis or paraphimosis. It achieves the removal and suturing of the foreskin mechanizedly, effectively reducing surgical time, lowering the risk of bleeding, and improving the precision and safety of the procedure. Its working principle involves clamping the foreskin tissue into the instrument, then using its built-in blade to cut it, simultaneously performing suturing.

[0002] These devices are typically made of stainless steel or other biocompatible materials, offering excellent durability and safety. The advantages of using a circumcision stapler include a shorter surgical time and a relatively faster patient recovery. Because the stapler's design ensures a clean incision, it reduces the likelihood of postoperative complications such as infection or bleeding. The use of a circumcision stapler also reduces patient discomfort during the procedure, improving overall comfort. As an advanced medical device, the circumcision stapler provides a more efficient and safer solution for circumcision.

[0003] The disadvantages of existing devices are: 1. When the foreskin is clamped into the locking part of the stapler, it needs to be locked by rotating the locking knob. Since there are no clear locking requirements, the operator can only judge whether the locking is in place by feel, which is prone to misjudgment. If the locking is too tight, it will cause the instrument to compress the tissue or blood vessels, and if it is too loose, it will cause incomplete foreskin cutting or uneven incision.

[0004] 2. When the cutting stapler is working, the ring blade pushes forward and squeezes against the inside of the glans to cut off the foreskin. However, with existing cutting staplers, after the blade is pushed forward to the end, the foreskin tissue may not be completely detached, requiring a second operation or tearing.

[0005] 3. The circumcision stapler contains a titanium staple. Because the titanium staple is a separate unit and the recovery speed of patients after injury varies, the titanium staple often falls out and needs to be cleaned multiple times. Summary of the Invention

[0006] To address the problems existing in the prior art, this invention provides a circumcision stapler that integrates cutting and suturing, enabling visual monitoring of the progress during tightening, reducing the risk of misjudgment, ensuring complete cutting during cutting, avoiding tissue adhesion, and improving operational efficiency and quality.

[0007] Therefore, the technical solution adopted by the present invention is: a circumcision stapler that integrates cutting and suturing, comprising a main body, a firing handle and a firing limiter on the main body, a ring-shaped blade assembly inside the main body, and a pin-stopping assembly inside the ring-shaped blade assembly, characterized in that a locking indicator assembly is provided at the rear end of the pin-stopping assembly, the locking indicator assembly can control the pin-stopping assembly to disengage or lock and is indicated by a locking indicator post, the pin-stopping assembly has a built-in soft pin-stopping ring, the pin-stopping assembly has an external pin magazine, and titanium pins are provided in the pin magazine, the ring-shaped blade assembly is fired and advanced forward to cut through the soft pin-stopping ring.

[0008] Preferably, the staple cartridge has a built-in titanium staple connecting ring, the annular blade assembly is provided with a staple pushing plate, and the annular cover of the staple fixing assembly is provided with a staple fixing seat on the outer ring of the front end. The staple pushing plate pushes the titanium staple forward, passes through the titanium staple connecting ring, passes through the patient's incision, and reaches the staple fixing seat to deform the titanium staple.

[0009] Preferably, the rear end of the annular cover of the anvil assembly is integrally connected to the guide rod, and the guide rod is connected to the locking knob of the locking indicator assembly. A cavity is formed inside the locking knob, and an indicator reset spring and a locking indicator post are provided inside the cavity.

[0010] Preferably, a titanium nail protective ring is also provided at the front of the titanium nail connecting ring.

[0011] Preferably, the rear end of the anvil forms a concave cavity.

[0012] The beneficial effects of this invention are as follows: 1. By combining the locking indicator component and the anvil component in a linked structure, the locking progress of the stapler can be visualized, avoiding the problem of being too tight or too loose when riveting the foreskin, and reducing the difficulty of operation.

[0013] 2. A soft blade ring is built into the pin assembly to achieve one-step pressing and cutting, avoiding problems such as foreskin adhesion and tissue tearing, and reducing the probability of secondary bleeding during the cutting process.

[0014] 3. After passing through the patient's incision via the titanium nail linking ring, the titanium nail reaches the anvil, deforms, and then anastomoses with the incision, linking multiple titanium nails together to avoid frequent nail detachment. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figures 1-2 The illustrated circumcision stapler, which integrates cutting and suturing, includes a main body 6, a firing handle 7 and a firing limiter 8 on the main body, a ring-shaped blade assembly 5 inside the main body, a pin assembly 1 inside the ring-shaped blade assembly 5, and a locking indicator assembly 91 at the rear end of the pin assembly 1. The locking indicator assembly 91 controls the pin assembly to disengage or lock and is indicated by a locking indicator post. The pin assembly 1 has a built-in soft pin ring 11 and an external pin magazine 4 containing titanium pins 41. When fired, the ring-shaped blade assembly 5 advances forward, cutting through the soft pin ring 11. The pin assembly 1 includes a ring-shaped cover at the front end, which covers the glans penis, with the foreskin placed outside the ring-shaped cover.

[0020] Specifically, the rear end of the annular cover of the anvil assembly is integrally connected to a guide rod. This guide rod is connected to the locking knob 9 of the locking indicator assembly. A cavity is formed within the locking knob, and an indicator return spring 912 and a locking indicator post 911 are installed within the cavity. In this technical solution, the locking knob 9 is connected to the connecting guide rod. Rotating the locking knob controls the entry and exit position of the anvil assembly 1. When the indicator post 911 inside the locking indicator assembly 91 is completely flush with the outer end face of the indicator assembly 91, the anvil assembly is locked in place. This achieves a visible locking progress for the stapler, avoiding the problem of excessive tightness or looseness when riveting and locking the foreskin, and reducing operational difficulty.

[0021] Specifically, the titanium staple 41 is a ring-shaped integral structure set inside the staple cartridge 4. This avoids the frequent occurrence of suture staples falling out one after another, thus solving the problem of repeated cleaning.

[0022] In one embodiment, the staple cartridge 4 contains a titanium staple linking ring 3. The annular blade assembly is equipped with a staple pusher plate 51, and the annular cover of the staple-holding assembly has an anvil seat 10 on its outer ring at the front end. The staple pusher plate 51 pushes the titanium staple 41 forward, through the titanium staple linking ring 3, through the patient's incision, and reaches the anvil seat 10, causing the titanium staple to deform. The staple pusher plate 51 pushes the titanium staple 41 forward, through the titanium staple linking ring 3, through the patient's incision, and reaches the anvil seat 12, causing the titanium staple to deform and fit the incision, thus linking multiple titanium staples 41 together and preventing frequent staple detachment and repeated cleaning.

[0023] Specifically, a titanium nail protective ring 2 is provided at the front of the titanium nail connecting ring 3 for protection. The rear end of the anvil 10 forms a concave cavity.

[0024] The procedure for using the circumcision stapler of the present invention is as follows: Rotate the locking knob 9 counterclockwise until the pin assembly is completely disengaged. At this time, the indicator reset spring 912 will push the locking indicator post 911 to complete reset. Place the patient's glans penis inside the annular cover of the pin assembly 1, and place the foreskin outside the annular cover. After fixing, rotate the locking knob 9 clockwise until the indicator post 911 inside the locking indicator assembly 91 is completely flush with the outer end face of the indicator assembly 91.

[0025] After removing the firing limiter 8, grip the firing handle 7 until it reaches the main body limit. At this time, the ring blade assembly 5 pushes forward to cut the patient's foreskin, while the soft abutment ring 11 cuts through, thus completely cutting off the patient's foreskin. The pusher plate 51 at the rear end of the ring blade assembly 5 pushes the titanium nail 41 forward, through the titanium nail connecting ring 3, through the patient's incision, and reaches the abutment seat 12 to deform the titanium nail and fit the incision.

[0026] This invention solves the problems of existing staplers where the locking progress is not visible and the foreskin is either too tight or too loose when tightening with a screw-on rivet. It also solves the problems of existing staplers causing incomplete cutting during pressing and cutting, leading to foreskin adhesion and tissue tearing, thus reducing the probability of secondary bleeding during cutting. Furthermore, it addresses the problem of frequent titanium staple detachment after surgery, requiring repeated cleaning.

[0027] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
