Problems solved by technology

[0003] For the convenience of molding and the versatility to different application environments, the absorbable bone plate often adopts a planar structure. When it is directly applied to fix the fracture site in a curved environment, the absorbable bone plate will be deformed passively to fit the curved surface of the fracture site. In this way, on the one hand, the internal stress generated by the deformation inside the absorbable bone plate will affect the strength and life of the absorbable bone plate itself; on the other hand, the reaction force generated by the passive deformation of the absorbable bone plate will act on the fracture site, thereby affecting Normal rehabilitation of the fracture site and quality of life of the patient

Embodiment 1

[0044] An absorbable bone plate profiling structure, such as figure 1 As shown, it includes a frame 1, the upper surface of the frame 1 is provided with a bone plate fixing jig 2, the bone plate fixing jig 2 includes a connecting shaft 22 and a plurality of clamp joint units 21, every two adjacent clamp joint units 21 pass through The connecting shaft 22 is hingedly connected, and the two clamp joint units 21 at both ends of the bone plate fixing clamp 2 are hingedly connected to the upper surface of the frame 1, and a plurality of driving parts 4 are fixedly arranged inside the frame 1, and the plurality of driving parts 4 are connected with the connecting shaft. 22 are in one-to-one correspondence and are used to drive the connecting shaft 22 to rise, thereby driving the adjacent two clamp joint units 21 to be arched upward to form a bent shape, and the upper surface of the bone plate fixing clamp 2 is relatively fixed with an absorbable bone plate body 3 , a heating device ...

Embodiment 2

[0052] A method for profiling and shaping an absorbable bone plate, comprising the following steps:

[0053] S1. Align the clamping hole 31 of the absorbable bone plate body 3 with the clamping shaft 211, and place the absorbable bone plate body 3 on the bone plate fixing fixture 2 horizontally;

[0054] S2. Make the designated driver 4 drive the connecting shaft 22 to move upward, thereby driving the two clamp joint units 21 correspondingly connected to the connecting shaft 22 to form a certain angle, and the angle measuring sensor 8 detects the included angle between the two clamp joint units 21, and When the included angle reaches the specified angle, the driving member 4 stops moving;

[0055] S3, the infrared heating device corresponding to the connecting shaft 22 that moves upward is activated to provide heat for the profiling deformation position of the absorbable bone plate body 3, and the temperature is kept at 80-160 degrees Celsius, and the heating time is 10 minute...

Abstract

The invention relates to an absorbable bone plate profiling shaping structure and a method thereof, which belong to the technical field of absorbable bone plates. The plate fixing jig includes a plurality of jig joint units connected end to end and a connecting shaft arranged between every two adjacent jig joint units, and every two adjacent jig joint units are hingedly connected by the connecting shaft, and the bone plate fixing jig The body of the absorbable bone plate is relatively fixed on the top, and the frame is fixed with a plurality of driving parts. Each driving part is fixed to one end of the corresponding connecting shaft to drive the connecting shaft to move upward. A heating device is installed inside the connecting shaft, which can A cooling system for cooling is installed on the upper part of the absorbable bone plate to overcome the limitations of the absorbable bone plate in the curved surface environment of the fracture site, greatly reduce or eliminate the internal stress of the absorbable bone plate, and improve the performance of the absorbable bone plate. strength and longevity.

Description

technical field [0001] The invention relates to the technical field of absorbable bone plates, in particular to an absorbable bone plate profiling structure and a method thereof. Background technique [0002] With the development of science and technology and medical technology, polylactic acid and other absorbable materials are gradually replacing titanium, stainless steel and other metal materials in orthopaedic fixation surgery due to their good in vivo metabolic properties and strength maintenance capabilities. Among them, absorbable bone plates are often used together with bone nails for internal fixation of fractures of cartilage, cortical bone and other tissues, and can bear certain torsional, bending and shearing forces. [0003] For the convenience of molding and the versatility of different application environments, the absorbable bone plate often adopts a flat structure. When it is directly applied to the fixation of the fracture site in a curved environment, the ...
