Description

Technical Field

[0001] This utility model relates to the field of titanium clamp technology, and in particular to a stepped spring-loaded nail feeder for titanium clamps. Background Technology

[0002] Titanium clips are commonly used in medical procedures, especially in minimally invasive surgery, to clamp and close blood vessels or tissues. They are made of high-strength titanium to ensure sufficient strength and corrosion resistance while remaining lightweight. Titanium clips are designed to minimize damage to surrounding tissues and provide a quick and reliable closure.

[0003] In existing titanium clip pliers, both the spring-loaded nail feeder and the titanium nail are installed in the nail magazine. When they slide to the left in the magazine, they generate sliding friction. In particular, when the spring-loaded nail feeder pushes the titanium nail, the head of the spring-loaded nail feeder pusher will deform slightly, increasing the friction between it and the inner wall of the nail magazine. In severe cases, this can cause the clip to jam. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a stepped spring-loaded nail feeder for titanium clamps.

[0005] This utility model is achieved using the following technical solution: a stepped spring-loaded nail feeder and pusher for titanium clamps, comprising a clamp head, a closing rod at the right end of the clamp head, a clamp head cover fixedly connected to the surface of the closing rod, a nail rod slidably connected to the inner wall of the closing rod, a nail magazine fixedly connected to the inner wall of the closing rod, titanium nails disposed inside the nail magazine, a steel pipe fixedly connected to the surface of the closing rod, a closing strip fixedly connected to the inner wall of the closing rod, an upper connecting seat fixedly connected to the surface of the closing rod, a lower connecting seat fixedly connected to the lower end of the upper connecting seat, a fixing strip fixedly connected to the inner wall of the closing rod, a clamp head closing seat snapped into the right end of the closing rod, and a spring-loaded nail feeder and pusher slidably connected to the inner wall of the nail magazine.

[0006] The above technical solution involves pushing the nail feeder seat to slide inwards towards the closing rod, while simultaneously moving the left side of the nail feeder seat to push the spring-loaded pin. This spring-loaded pin then pushes the second nail feeder spring to the left, which in turn pushes the spring-loaded nail pusher to the left. The spring-loaded nail pusher then pushes the titanium nail outwards, thus ejecting the titanium nail. By using a stepped pushing mechanism to reduce the thickness of the spring-loaded nail pusher, friction during sliding is reduced. The nail magazine ensures that the spring-loaded nail pusher can slide stably, guaranteeing accurate ejection of the titanium nail.

[0007] As a further improvement to the above solution, the right end of the pliers head is fixedly connected to the inner wall of the pliers head cover, and the inner wall of the closing rod is slidably connected to a nail feeding rod seat.

[0008] The above technical solution uses a top cover to fix the pliers head, and two pliers heads are provided.

[0009] As a further improvement to the above solution, a spring-loaded plastic pin is fixedly connected to the left end of the nail feeding rod seat, and the surface of the spring-loaded plastic pin is slidably connected to the inner wall of the closing rod.

[0010] The above technical solution uses a closing rod to limit the movement of the spring-loaded plastic pin, ensuring the stability of the spring-loaded plastic pin during movement.

[0011] As a further improvement to the above solution, a second nail-feeding spring is provided at the left end of the spring-loaded plastic pin, and the end of the second nail-feeding spring away from the spring-loaded plastic pin is fixedly connected to the spring-loaded nail-feeding pusher piece.

[0012] With the above technical solution, when the spring-loaded plastic pin moves, it will drive the second nail-feeding spring to move, which in turn will push the spring-loaded nail-feeding pusher to move.

[0013] As a further improvement to the above solution, a transmission frame sleeve is slidably connected to the surface of the nail feeding rod seat, and a first nail feeding spring is provided at the right end of the transmission frame sleeve.

[0014] As a further improvement to the above solution, the first nail feeding spring is sleeved on the surface of the nail feeding rod seat, and an open retaining ring is fixedly connected to the surface of the nail feeding rod seat.

[0015] As a further improvement to the above solution, a return spring is sleeved on the surface of the nail feeding rod seat, and the return spring is located at the left end of the first nail feeding spring.

[0016] With the above technical solution, when the nail feed rod seat slides to the left, the transmission frame sleeve will squeeze the return spring. After the nail feed rod seat is released, the return spring will reset the nail feed rod seat.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention utilizes a nail holder, a spring-loaded plastic pin, a second nail-feeding spring, and a spring-loaded nail-feeding pusher. Specifically, the nail-feeding rod holder slides inward towards the closing rod, while the left side of the nail-feeding rod holder pushes the spring-loaded plastic pin, causing the spring-loaded plastic pin to move to the left. The second nail-feeding spring then pushes the spring-loaded nail-feeding pusher to the left, which in turn pushes the titanium nail outward, thus ejecting the titanium nail. By using a stepped pusher mechanism, the thickness of the spring-loaded nail-feeding pusher is reduced, thereby reducing friction during sliding and ensuring accurate ejection of a single titanium nail.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example:

[0029] Please combine Figure 1-6This embodiment of a stepped spring-loaded nail feeder for titanium clamps includes a clamp head 1, a closing rod 2 at the right end of the clamp head 1, a clamp head cover 4 fixedly connected to the surface of the closing rod 2, a nail rod 5 slidably connected to the inner wall of the closing rod 2, a nail magazine 6 fixedly connected to the inner wall of the closing rod 2, titanium nails 3 disposed inside the nail magazine 6, a steel pipe 7 fixedly connected to the surface of the closing rod 2, a closing strip 8 fixedly connected to the inner wall of the closing rod 2, an upper connecting seat 9 fixedly connected to the surface of the closing rod 2, a lower connecting seat 10 fixedly connected to the lower end of the upper connecting seat 9, a fixing strip 11 fixedly connected to the inner wall of the closing rod 2, and a clamp head closing seat 1 engaged at the right end of the closing rod 2. 2. A spring-loaded nail feeder 17 is slidably connected to the inner wall of the nail magazine 6. This pushes the nail feeder 13 to slide inward toward the closing rod 2. At the same time, the left side of the nail feeder 13 pushes the spring-loaded plastic pin 20 to move, causing the spring-loaded plastic pin 20 to push the second nail feeder 19 to move to the left. Then, the second nail feeder 19 pushes the spring-loaded nail feeder 17 to move to the left, and the spring-loaded nail feeder 17 pushes the titanium nail 3 to move outward, thereby pushing the titanium nail 3 out. By pushing the spring-loaded nail feeder 17 in a stepped manner, the thickness of the spring-loaded nail feeder 17 is reduced, thereby reducing the friction during its sliding process and ensuring that a titanium nail 3 can be pushed out accurately.

[0030] The right end of the pliers head 1 is fixedly connected to the inner wall of the pliers head cover 4. The inner wall of the closing rod 2 is slidably connected to the nail feeding rod seat 13. The closing rod 2 limits the movement of the nail feeding rod seat 13, ensuring that the nail feeding rod seat 13 is more stable when sliding.

[0031] A spring-loaded plastic pin 20 is fixedly connected to the left end of the nail feeding rod seat 13, and the surface of the spring-loaded plastic pin 20 is slidably connected to the inner wall of the closing rod 2.

[0032] A second nail-feeding spring 19 is provided at the left end of the spring-loaded plastic pin 20. The end of the second nail-feeding spring 19 away from the spring-loaded plastic pin 20 is fixedly connected to the spring-loaded nail-feeding pusher piece 17.

[0033] A transmission frame sleeve 14 is slidably connected to the surface of the nail feeding rod seat 13, and a first nail feeding spring 15 is provided at the right end of the transmission frame sleeve 14.

[0034] The first nail feeding spring 15 is sleeved on the surface of the nail feeding rod seat 13, and an open retaining ring 16 is fixedly connected to the surface of the nail feeding rod seat 13.

[0035] A return spring 18 is fitted on the surface of the nail feeding rod seat 13, and the return spring 18 is located at the left end of the first nail feeding spring 15.

[0036] The implementation principle of the stepped spring-loaded nail feeder and pusher plate of the titanium clamp in this embodiment is as follows: During use, the titanium nail 3 is installed inside the nail magazine 6. The nail feeder seat 13 is pushed to slide inward towards the closing rod 2. Simultaneously, the left side of the nail feeder seat 13 pushes the spring-loaded plastic pin 20 to move, causing the spring-loaded plastic pin 20 to push the second nail feeder spring 19 to move to the left. Then, the second nail feeder spring 19 pushes the spring-loaded nail feeder and pusher plate 17 to move to the left, which in turn pushes the titanium nail 3 outward, thereby pushing the titanium nail 3 outward. The stepped push spring nail feeder 17 reduces its thickness, thereby reducing friction during sliding and ensuring accurate delivery of a titanium nail 3. When the nail feeder 13 slides to the left, the transmission frame sleeve 14 compresses the return spring 18. After releasing the nail feeder 13, the return spring 18 resets the nail feeder 13 and simultaneously pulls the spring plastic pin 20 to slide to the right on the inner wall of the closing rod 2, pulling the spring nail feeder 17 to the right and resetting it.

[0037] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
