Description

Technical Field

[0001] This utility model relates to the field of dental implant clamping technology, specifically an implant fixation clamp. Background Technology

[0002] Dental implants, also known as artificial tooth roots, are an important type of artificial implant in the field of oral implantology. They are specifically artificial implants that are surgically inserted into the jawbone at the site of a missing tooth to support the superstructure (such as a crown). Commonly used types of implants include tapered threaded implants, which have a spiral surface that can integrate well with the alveolar bone, increasing the contact area between the alveolar bone and the implant, thereby enhancing stability.

[0003] In dental surgery, forceps are generally used to pick up and place implants. Because the outer surface of the implant is designed in a spiral shape, the surface of the implant is an uneven curved surface. When using forceps to hold the implant, the flat surface of the forceps tip is not easy to adapt to the uneven curved surface of the implant to firmly hold and fix the implant. In particular, when the forceps holding the implant are exchanged between the assistant and the attending physician, the implant is more likely to fall off the forceps. Utility Model Content

[0004] The purpose of this invention is to provide an implant fixation clamp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An implant fixation clamp, comprising:

[0007] There are two handles. A shaft is fixed to the inside of one handle. The shaft is slidably inserted into the other handle. A nut is screwed onto one end of the shaft that passes through the handle.

[0008] The reset component, fixed between the two handles, enables the two handles that are moving close to each other to automatically move to their initial positions in opposite directions.

[0009] A clamping rod is rotatably connected to a handle at a corresponding position, and an arc-shaped clamping block is fixed to one end of the clamping rod.

[0010] The second clamping rod is rotatably connected to the handle at the corresponding position, and two arc-shaped clamping blocks are fixed at one end of the second clamping rod;

[0011] The locking mechanism, fixed to one end of the clamping rod, can fix the clamping rod to the handle.

[0012] Furthermore, the handle has an arc-shaped cross-section, and a traction rope is fixed between one end of the two handles.

[0013] Furthermore, one end of the shaft is provided with an external thread that engages with the nut, and a rubber sleeve is fitted and fixed to the outside of the handle.

[0014] Furthermore, the reset component includes:

[0015] A square tube is fixedly connected to the handle at the corresponding position;

[0016] A sliding rod is slidably connected to a square tube, and the end of the sliding rod facing away from the square tube is fixedly connected to a handle at a corresponding position.

[0017] A return spring is fixed between the slide rod and the square tube.

[0018] Furthermore, one end of the clamping rod 2 is fixed with a connecting block, and the connecting block is fixedly connected to the arc-shaped clamping block 2.

[0019] Furthermore, the locking mechanism includes:

[0020] The fixing base is fixed to one end of the connecting clamping rod;

[0021] The connecting shaft is slidably inserted into the fixed base, and two circular blocks are fixed on the outer side of the connecting shaft.

[0022] Furthermore, one end of the connecting shaft is provided with a rounded corner, and one end of the handle is provided with a through-hole for movable insertion into the connecting shaft.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. By holding the two handles, clamping rod one and clamping rod two move closer to each other, and the arc-shaped block one on clamping rod one and the arc-shaped clamping block two on clamping rod two move closer to each other, thus clamping and fixing the implant. By setting both arc-shaped clamping blocks one and two to be arc-shaped, and fixing them at the ends of clamping rod one and clamping rod two respectively, the arc-shaped clamping blocks one and two can be inserted into the spiral groove on the outside of the implant, so that the arc-shaped clamping blocks one and two can firmly clamp and fix the implant.

[0025] 2. By fixing a shaft to one handle, with one end of the shaft slidingly connected to another handle, when it is necessary to transfer the clamp holding the implant, the nut at the end of the shaft can be turned in advance to fix the two handles in a close clamping state. This ensures that even if the handles are released, the two handles remain clamped, and clamping rod one and clamping rod two work together to continue to clamp and fix the implant, which to a certain extent prevents the implant from falling during the transfer process.

[0026] 3. By rotating both clamping rods (including clamping rod one and clamping rod two) onto the corresponding handles, when the clamping rods are not needed to clamp the implant, they can be rotated between the two handles to store the clamping rods, which reduces the size of the clamp and makes it convenient to carry and store.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1, please refer to Figure 1-4In this embodiment of the present invention, an implant fixation clamp includes two handles 100. A shaft 110 is fixed to the inner side of one handle 100. The shaft 110 is slidably inserted into the other handle 100. A nut 111 is screwed onto one end of the shaft 110 through the handle 100. A reset component 200 is fixed between the two handles 100. The reset component 200 enables the two handles 100, which are moving close to each other, to automatically move to their initial positions in opposite directions. One end of each handle 100 is rotatably connected to a clamping rod 300 and a clamping rod 400, respectively. One end of the clamping rod 300 is fixed with an arc-shaped clamping block 310. One end of the clamping rod 400 is fixed with two arc-shaped clamping blocks 410. One end of the clamping rod 300 is provided with a locking mechanism 500, which can fix the clamping rod 300 to the handle 100.

[0034] Specifically, by fixing an inclined arc-shaped clamping block 310 to the end of clamping rod 300 and an inclined arc-shaped clamping block 410 to the end of clamping rod 400, when the two clamping rods are brought closer together to clamp the implant by holding the handle 100, the arc-shaped clamping blocks 310 and 410 on the two clamping rods can first be inserted into the spiral groove on the outside of the implant and then clamp and fix the implant. This is beneficial for the clamp to firmly and stably clamp and fix the implant. By inserting a shaft 110 between the two handles 100 and tightening the nut 111 on the shaft 110, the two handles 100 remain in the clamping state even when the handles 100 are accidentally released by the hand, which can effectively prevent the implant from falling during the transfer of the clamp.

[0035] like Figure 1 As shown, in this embodiment, the cross-section of the handle 100 is arc-shaped, and a traction rope 120 is fixed between one end of the two handles 100. The outer side of the handle 100 is set as an arc surface to improve the comfort of the user holding the handle 100. The traction rope 120 is fixed between the two handles 100. The traction rope 120 makes it convenient to hang the clamp on the rack for disinfection, and also makes it convenient to suspend the clamp on the operating table.

[0036] like Figure 3 As shown, in this embodiment, one end of the shaft 110 is provided with an external thread that engages with the nut 111. A rubber sleeve is fixed to the outer side of the handle 100. After the two handles 100 are held and moved closer together, the nut 111 at the end of the shaft 110 can be rotated to fix the two handles 100 that are close to each other on the shaft 110, thereby keeping the handles 100 in a clamped state at all times.

[0037] like Figure 4As shown, in this embodiment, the reset assembly 200 includes a square tube 210 fixedly connected to the handle 100 at the corresponding position. A slide rod 220 slides inside the square tube 210. One end of the slide rod 220 away from the square tube 210 is fixedly connected to the handle 100 at the corresponding position. A reset spring 230 is fixed between the slide rod 220 and the square tube 210.

[0038] In this embodiment, when the two handles 100 move closer to each other, the slide bar 220 compresses the return spring 230. The return spring 230 stores elastic potential energy. After the handles 100 are released, the two handles 100 automatically unfold in opposite directions under the elastic force of the return spring 230, making it convenient for the user to hold the handles 100 again to clamp the implant.

[0039] like Figure 1 As shown, in this embodiment, a connecting block 420 is fixed to one end of the clamping rod 400. The connecting block 420 is fixedly connected to the arc-shaped clamping block 410, thereby distributing the two arc-shaped clamping blocks 410 at different positions at the end of the clamping rod 400 to adapt to different positions of the spiral groove on the outside of the implant. In addition, a protrusion is fixed to the bottom of the connecting block 420. The protrusion ensures that the arc-shaped clamping block 410 below the connecting block 420 is not on the same plane as the arc-shaped clamping block 410 above the connecting block 420, adapting to the conical shape of the implant, so that the arc-shaped clamping blocks 410 at different positions can be embedded into the spiral groove of the implant.

[0040] like Figure 1 As shown, in this embodiment, a prior art spring telescopic rod 320 is fixed between clamping rod one 300 and clamping rod two 400, so that when one clamping rod is rotated, the other clamping rod rotates synchronously under the drive of the spring telescopic rod 320. After the position of clamping rod one 300 is fixed by the locking mechanism 500, the position of clamping rod two 300 is also fixed. At the same time, the telescopic feature of the spring telescopic rod 320 is used to meet the change of the distance between the two clamping rods during the process of clamping the implant.

[0041] Example 2, based on Example 1, aims to fix the rotating and retracted clamping rod 300 and clamping rod 400 in the adjusted position.

[0042] like Figure 2 and Figure 3 As shown, in this embodiment, the locking mechanism 500 includes a fixed base 510 fixed to the clamping rod 300. A connecting shaft 520 is slidably inserted inside the fixed base 510. A circular block 521 and a circular block 522 are fixed on the outside of the connecting shaft 520.

[0043] Specifically, when it is necessary to fix the position of the clamping rod in the rotated unfolded or rotated retracted state, push the circular block 521 by hand to insert the connecting shaft 520 into the circular hole of the handle 100, so that the clamping rod 300 and the handle 100 are fixed together through the connecting shaft 520. The clamping rod 300 cannot rotate, and the clamping rod 400 cannot rotate through the spring telescopic rod 320, thus fixing the position of the two clamping rods after rotation adjustment.

[0044] like Figure 2 As shown, in this embodiment, one end of the connecting shaft 520 is provided with a rounded corner, and one end of a handle 100 is provided with a round hole that can be movably inserted into the connecting shaft 520. The rounded corner allows the end of the connecting shaft 520 to be smoothly inserted into the round hole of the handle 100, thereby fixing the handle 100 and the clamping rod 300 together through the connecting shaft 520.

[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
