Description

Technical Field

[0001] The utility model relates to the technical field of titanium nail cutting, in particular to a medical titanium nail cross-section sharp-angle cutter. Background Art

[0002] A titanium nail is a metal nail made of medical titanium and is commonly used in medical surgery. During the processing of titanium nails, the titanium wire needs to be cut using mechanical tools such as a cutter to make the two ends of the titanium nail sharp. When penetrating tissue or materials, the titanium nail has a smaller contact area and higher pressure, making it easier to penetrate, significantly reducing the force required during the puncture process and making the operation easier.

[0003] At present, when titanium nails are produced, a V-shaped cutter is used to cut the titanium wire in cooperation with a V-shaped groove. During the cutting process, the titanium wire is easily pressed to the bottom of the V-shaped groove by the cutter before being cut. Such cutting will cause the titanium nail to be cut straight, resulting in rounded corners of the titanium nail, which leads to a low yield rate of sharp-angle titanium nails. Therefore, the utility model proposes a medical titanium nail cross-section sharp-angle cutter. Utility Model Content

[0004] The utility model aims to provide a medical titanium nail cross-section sharp angle cutter to solve the problems raised by the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A cutting assembly, arranged between the knife handle and the knife seat, for performing sharp-angle cutting processing on the titanium nail;

[0009] A contraction component is arranged at the bottom of the knife handle and is used to drive the cutting component to perform oblique cutting on the titanium nail;

[0010] The limiting assembly is arranged on the top of the knife seat and is used to cooperate with the contraction assembly to drive the cutting assembly to perform oblique cutting movement.

[0011] Preferably, the shrinkage assembly comprises two elastic blocks and a shrinkage groove, the two elastic blocks are fixedly connected to two sides of the bottom of the handle, and the shrinkage groove is arranged between the two elastic blocks.

[0012] Preferably, the cutting assembly comprises two connecting bevel blocks, two cutters and two bevel blocks, the two connecting bevel blocks are fixedly connected to the bottom of the elastic block, the two cutters are fixedly connected to the bottom of the connecting bevel blocks, and the two bevel blocks are fixedly connected to the bottom of the cutters.

[0013] Preferably, the limiting assembly comprises a protrusion, a V-shaped groove and a through hole, the protrusion is fixedly connected to the top of the knife seat, the V-shaped groove is arranged on the top of the protrusion, and the through hole is arranged on both sides of the protrusion.

[0014] Preferably, a flat groove is provided between the two knives.

[0015] Preferably, an arc-shaped opening is provided at the connection between the connecting bevel block and the knife handle.

[0016] Preferably, the inclination angle of the bevel block is smaller than the inclination angle of the V-shaped groove.

[0017] Preferably, the perforations are arranged in several groups.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The utility model drives the cutting assembly to move by controlling the knife handle so that the bevel block contacts the inner wall of the V-shaped groove, and continues to drive the knife handle and the cutting assembly to move downward. Under the extrusion and limiting action of the two inner sides of the V-shaped groove, the two elastic blocks are offset to the contraction groove, and the elastic blocks drive the bevel block to move downward along the inner wall of the V-shaped groove. The bevel block performs sharp-angle cutting on the titanium wire inside the perforation. By arranging two bevel blocks to cut both ends of the titanium wire at the same time, the two bevel blocks are prevented from cutting the titanium nail straight, and the cutting of rounded titanium nails is avoided, thereby improving the sharp-angle yield rate of the titanium nails after cutting.

DETAILED DESCRIPTION

[0025] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a medical titanium nail cross-section sharp-angle cutting knife, comprising: a knife seat 1; a knife handle 11, which is arranged above the knife seat 1; a cutting component 3, which is arranged between the knife handle 11 and the knife seat 1, and is used to perform sharp-angle cutting processing on the titanium nail; a contraction component 2, which is arranged at the bottom of the knife handle 11, and is used to drive the cutting component 3 to perform oblique cutting processing on the titanium nail; a limiting component 4, which is arranged at the top of the knife seat 1, and is used to cooperate with the contraction component 2 to drive the cutting component 3 to perform oblique cutting movement.

[0028] The shrinking assembly 2 includes two elastic blocks 21 and a shrinking groove 22. The two elastic blocks 21 are fixedly connected to both sides of the bottom of the knife handle 11, and the shrinking groove 22 is arranged between the two elastic blocks 21; the cutting assembly 3 includes two connecting oblique blocks 31, two knives 32 and two bevel blocks 33. The two connecting oblique blocks 31 are fixedly connected to the bottom of the elastic block 21, the two knives 32 are fixedly connected to the bottom of the connecting oblique blocks 31, and the two bevel blocks 33 are fixedly connected to the bottom of the knives 32; the limiting assembly 4 includes a protrusion 41, a V-shaped groove 42 and a perforation 43. The protrusion 41 is fixedly connected to the top of the knife seat 1, the V-shaped groove 42 is arranged at the top of the protrusion 41, and the perforation 43 is arranged on both sides of the protrusion 41; a flat groove 5 is arranged between the two knives 32; an arc-shaped opening 6 is opened at the connection between the connecting oblique block 31 and the knife handle 11; the inclination angle of the bevel block 33 is smaller than the inclination angle of the V-shaped groove 42.

[0029] The specific scheme is as follows: the tool handle 11 is controlled to drive the cutting assembly 3 to move toward the tool holder 1, so that the two bevel blocks 33 are in conflict with the inner wall of the V-shaped groove 42, and the tool handle 11 is continued to be driven to move downward. The tool handle 11 drives the elastic block 21, the connecting bevel block 31, the tool 32 and the bevel block 33 to move downward. Under the extrusion and limiting action of the two inner sides of the V-shaped groove 42, the two elastic blocks 21 are offset toward the contraction groove 22. The elastic block 21 drives the tool 32 and the bevel block 33 to move downward along the inner wall of the V-shaped groove 42 through the connecting bevel block 31. The two bevel blocks 33 perform sharp corner cutting on the titanium wire inside the perforation 43. By setting two bevel blocks 33 to cut both ends of the titanium wire at the same time, the two bevel blocks 33 are prevented from cutting the titanium nails straightly, and the cutting of rounded titanium nails is avoided, thereby improving the sharp corner yield of the titanium nails after cutting.

[0030] Embodiment 2: Figure 4 As shown, a medical titanium nail cross-section sharp angle cutter disclosed in the second embodiment of the present invention has a structure that is basically the same as that in the first embodiment, except that a plurality of groups of through holes 43 are provided.
