Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically a pet orthopedic bone plate. Background Technology

[0002] A bone plate is a medical device used for fracture fixation. Its main function is to be fixed to the bones at both ends of a fracture using screws to maintain the correct position and stability of the bones and promote fracture healing. In practice, bone plates are used in conjunction with screws. Although screws are not part of the bone plate, they are used together to fix the plate by screwing it into the bone. Types of screws include cortical bone screws and cancellous bone screws.

[0003] Some modern bone plates are designed with a compression mechanism, meaning there is a special compression structure between the screw and the bone plate to prevent screw loosening and provide more stable fixation. This compression mechanism is generally achieved through screw compression holes, which are through holes for fixing the screws. Existing screw compression hole designs are countersunk holes with stepped vertical sidewalls. This right-angle design generates significant internal stress, requiring thicker steel plates, resulting in poor fracture resistance and limited plasticity. Utility Model Content

[0004] The purpose of this invention is to provide a pet orthopedic bone plate to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A pet orthopedic bone plate includes a main body with several evenly distributed fixation holes. The surfaces of the main body where the openings of the fixation holes are located are the proximal bone surface and the distal bone surface, respectively. Each fixation hole comprises a threaded end and a screw clamping end. The threaded end is near the proximal bone surface, and the screw clamping end is near the distal bone surface. The screw clamping end adopts an inner conical clamping structure, that is, the diameter of the fixation hole gradually decreases from the outside to the inside.

[0007] In a further embodiment, the inner wall of the screw pressure end is arc-shaped.

[0008] In a further embodiment, the inner wall of the screw pressure end is threaded.

[0009] In a further embodiment, the near-bone surface is patterned.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The screw pressing end of the fixing through hole of this utility model adopts an inner conical pressing structure, that is, the diameter of the fixing through hole gradually decreases from the outside to the inside. It is preferred to adopt an arc shape or a thread shape. This structure can effectively reduce the generation of internal stress, improve the anti-fracture performance, and the thickness of the steel plate can be relatively thinner when the performance is the same, and the plasticity is better.

[0012] Second, the surface of this utility model near the bone has a pattern with varying concave and convex shapes, which can effectively increase the friction between the bone plate body and the bone contact surface and improve the stability of fixation. Attached Figure Description

[0018] 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.

[0019] Example 1

[0020] like Figure 1-2 As shown, this embodiment provides a pet orthopedic bone plate, including a bone plate body 1. The bone plate body 1 has several evenly distributed fixation through holes 2. The surfaces of the bone plate body 1 where the openings of the fixation through holes 2 are located are the distal bone surface 4 and the patterned proximal bone surface 3, respectively. The fixation through hole 2 includes a threaded end 5 and a screw pressing end 6. The threaded end 5 is close to the proximal bone surface 3, and the screw pressing end 6 is close to the distal bone surface 4. The screw pressing end 6 adopts an inner conical pressing structure, that is, the diameter of the fixation through hole 2 gradually decreases from the outside to the inside, and the inner wall of the screw pressing end 6 is arc-shaped.

[0021] In this embodiment, the screw pressing end 6 of the fixing through hole 2 adopts an inner conical pressing structure, that is, the diameter of the fixing through hole 2 gradually decreases from the outside to the inside, and the inner wall of the screw pressing end 6 is arc-shaped. This structure can effectively reduce the generation of internal stress, improve the anti-fracture performance, and the thickness of the steel plate of the same material can be relatively thinner under the condition of consistent performance, and the plasticity is better.

[0022] Example 2

[0023] like Figure 3-4 As shown

[0024] The difference between this embodiment and embodiment 1 is that the inner wall of the screw pressure end 6 is threaded. The other structures are the same as in embodiment 1, and will not be described again here.

[0025] In this embodiment, the screw pressing end 6 of the fixing through hole 2 adopts an inner conical pressing structure, that is, the diameter of the fixing through hole 2 gradually decreases from the outside to the inside, and the inner wall of the screw pressing end 6 is threaded. This structure can effectively reduce the generation of internal stress, improve the anti-fracture performance, and the thickness of the steel plate of the same material can be relatively thinner under the condition of consistent performance, and the plasticity is better.

[0026] In this embodiment, the thread end 5 of the fixing through hole 2 is adjusted from the original 1mm to 1.25mm. The screw used has a larger base diameter, which allows for better pressure stroke along the fracture line when screwed in. Under the same number of rotations, the number of downward rotations for pressure is reduced, which can achieve rapid pressure. In addition, the wrench specification is adjusted from the original T10 to T15, increasing the torque of the wrench so that it can be more precisely controlled and the expected pressure stroke can be achieved more accurately.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
