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 shaping structure, such as figure 1 As shown, including 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 jig joint units 21, and every two adjacent jig joint units 21 pass through The connecting shaft 22 is hingedly connected, and the two jig joint units 21 at both ends of the bone plate fixing jig 2 are hingedly connected to the upper surface of the frame 1. The inside of the frame 1 is fixedly provided with a plurality of driving parts 4, and the multiple driving parts 4 are connected to the connecting shaft. 22 correspond to each other and are used to drive the connecting shaft 22 to rise, thereby driving the two adjacent jig joint units 21 to arch upward to form a bent shape. The upper surface of the bone plate fixing jig 2 is relatively fixed with an absorbable bone plate body 3 A heating device is arranged inside t...

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 horizontally place the absorbable bone plate body 3 on the bone plate fixing jig 2;

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

[0055] S3. The infrared heating device corresponding to the upwardly moving connecting shaft 22 is activated to provide heat for the profiling deformation position of the absorbable bone plate body 3, and keep the temperature at 80-160 degrees Celsius, and the heating time is 10 minutes to 40 min...

Abstract

The invention relates to an absorbable bone plate profiling shaping structure and a method thereof, and belongs to the technical field of absorbable bone plate. The structure includes a rack; the upper surface of the rack is provided with a bone plate fixing fixture; the bone plate fixing fixture includes a plurality of end-to-end clamp joint units and connecting shafts arranged between each two adjacent clamp joint units, and each two adjacent fixture joint units are hinged and connected through the connecting shaft. The bone plate fixing fixture is relatively fixedly provided with an absorbable bone plate body. The rack is fixedly provided with a plurality of driving parts. Each driving part is fixed with one end of the corresponding connecting shaft to drive the corresponding connectingshaft to move upward. The connecting shafts are each internally provided with a heating device, and the upper part of the absorbable bone plate body is provided with a cooling system for cooling, sothe effects of overcoming the limitation of the absorbable bone plate when being applied in a curved surface environment of a fracture part, greatly reducing or eliminating the internal stress of theabsorbable bone plate, and improving the strength and life of the absorbable bone plate are achieved.

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 medical technology, absorbable materials such as polylactic acid are gradually replacing metal materials such as titanium and stainless steel in orthopedic fixation operations 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 in cartilage, cortical bone and other tissues, and can bear certain torsion, bending and shearing forces. [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...
