Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a ball head test die separation forceps. Background Technique

[0002] Ball head test dies are usually used in joint replacement surgeries or other related surgeries to test or simulate the ball head part of a joint. These test dies are usually temporarily placed in the joint to evaluate their fit, stability, or range of motion. When it is necessary to remove these test dies, doctors or surgical teams may use ball head test die separation forceps to firmly clamp the ball head test die and then separate it from the joint.

[0003] However, when separating ball head test dies of different sizes and in different situations, the conventional separation forceps are not very convenient to use. The bending degree of the forceps head and the length of the separation forceps cannot be quickly adjusted. For this reason, we propose a ball head test die separation forceps.

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment

[0024] Please refer to Figures 1-6 , a ball head test die separation pliers, including a handle 1, an adjusting component 2 is installed at the end of the handle 1, the adjusting component 2 includes a toothed groove column 201, a limiting plate 202, and a gear 203, and a pliers rod 3 is arranged at the end of the handle 1;

[0025] A positioning screw 4 is arranged on the pliers rod 3, a slot 301 is opened at the end of the pliers rod 3, a disassembly component 5 is arranged inside the slot 301, a pliers head 6 is arranged at the end of the pliers rod 3, and a convex block 601 is welded at the end of the pliers head 6.

[0026] In this embodiment, a convex block 601 is arranged on one side of the clamping block 502, and the convex block 601 is tightly attached to the inner wall of the slot 301 through the clamping block 502.

[0027] In this embodiment, a convex block 601 is clamped in the slot 301, and fixation can be achieved after the convex block 601 is inserted into the slot 301.

[0028] In this embodiment, the disassembly component 5 includes a telescopic spring 501 and a clamping block 502. A telescopic spring 501 is arranged inside the slot 301, a clamping block 502 is arranged at the end of the telescopic spring 501. After the convex block 601 slides into the slot 301 along the inclined wall of the clamping block 502, it is clamped by the telescopic spring 501 to achieve the effect of firm fixation.

[0029] In this embodiment, a gear 203 is installed inside the pliers rod 3, the toothed groove column 201 is meshed and connected with the gear 203, and a rotating rod passes through the center of the gear 203. After rotating the rotating rod, the gear 203 rotates to achieve transmission.

[0030] In this embodiment, a toothed groove column 201 is welded at the end of the handle 1, a limiting plate 202 is arranged at the end of the toothed groove column 201, a gear 203 is arranged on one side of the toothed groove of the toothed groove column 201. After the gear 203 rotates, it meshes with the toothed groove column 201, so that the toothed groove column 201 displaces along the extension line direction of the pliers rod 3, thereby realizing the length adjustment of the pliers rod 3.

[0031] In this embodiment, the pliers rod 3 is movably arranged at the end of the handle 1, and the pliers rod 3 can be quickly adjusted, which is convenient for use in different situations.

[0032] Working principle: Before use, select a suitable jaw 6 for disinfection, and then align it with the slot 301, so that the bump 601 slides into the slot 301 along the inclined wall of the latch 502. The force provided by the telescopic spring 501 makes the jaw 6 firmly connected to the jaw rod 3. Then, adjust the length of the jaw rod 3 using the adjustment assembly 2 according to the installation position of the ball head test die. After rotating the rotating rod, the gear 203 rotates. When the gear 203 meshes with the tooth groove column 201, the displacement of the tooth groove column 201 is realized. The tooth groove column 201 drives the handle 1 to displace, so that the distance between the handle 1 and the jaw rod 3 is adjusted. The displacement distance of the tooth groove column 201 is restricted by the limit plate 202 to prevent damage to the separating pliers. At the same time, the detachable nature of the jaw 6 allows for the individual replacement of the jaw 6, which can reduce waste of resources caused by replacement when it wears out.

[0033] In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "set", "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
