Embodiment 1

[0036] Such as Figure 1-Figure 8 As shown, the fusion locking plate provided by the embodiment of the present invention includes: a bone plate 10 with a plurality of positioning holes along the thickness direction, and a plurality of anti-slip protrusions arranged on one side of the bone plate 10 .

[0037] For ease of description, in this embodiment, the two opposite sides of the bone plate 10 along the thickness direction are respectively referred to as a first surface 11 and a second surface 12 , and anti-slip protrusions are provided on the first surface 11 of the bone plate 10 .

[0038] Such as Figure 7 with Figure 8 As shown, the cross-sectional shape of the bone plate 10 along the thickness direction is arc-shaped, and the anti-slip protrusions are arranged on the concave side of the bone plate 10 . In this way, the second surface 12 protrudes toward the arc, which is called a convex surface, and the opposite first surface 11 is a concave surface. The bone plate ...

Embodiment 2

[0059] Embodiment 2 of the present invention provides a wrist fusion structure, including a locking screw and the fusion locking plate provided in Embodiment 1 above, and the locking screw passes through the positioning hole of the fusion locking plate.

[0060] Further, the wrist fusion structure also includes titanium cable binding wires. During the fixation process, first use the locking screw to pass through the positioning hole on the fusion locking plate to be screwed into the site to be fixed, so as to fix the fusion locking plate to the site to be fixed; then use titanium cable binding wire to wrap the site to be fixed and the fusion lock The periphery of the plate, so as to further fix the fusion locking plate and the part to be fixed.

[0061] In the wrist fusion mechanism provided in this embodiment, the fusion locking plate is fixed to the patient’s part to be fixed through the action of the locking screw and the titanium cable binding wire, and the fusion locking ...

Abstract

The invention provides a fusion locking plate and a wrist fusion structure, which relate to the technical field of medical instruments and solve the problems of long time required for plate fixation and poor fixation stability in the fracture treatment process. The fusion locking plate comprises a bone plate, a plurality of positioning holes are arranged along the thickness direction of the bone plate, and a plurality of anti-skid protrusions are arranged on one side of the bone plate. The fusion locking plate is provided with an anti-skid protrusion, the friction force between the fusion locplate and the part to be fixed is large in the fixing process, the displacement is not liable to occur, the fixing part is convenient to install, and the fusion loc plate is more stable after fixing.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a fusion locking plate and a wrist fusion structure. Background technique [0002] Distal radius fracture is a common type of fracture in hand trauma. Surgical internal fixation can restore its good anatomical alignment, promote its early mobilization, and restore hand function. [0003] At present, straight steel plates or some conventional angled steel plates used for fracture fixation of distal radius fractures are difficult to fix in the distal part of the radius, and the ability to resist displacement of the fracture end is poor, and the purpose of firm fixation of distal radius fractures cannot be achieved. , It takes a long time to install the screws and is easy to loosen. Contents of the invention [0004] The purpose of the present invention is to provide a fusion locking plate to solve the technical problems in the prior art that the fixation time of the plat...
