Embodiment Construction

[0043] The application will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0044] At present, the size of the bone plate is usually fixed, which is poorly adaptable to patients with different body shapes and affected parts in different situations. At the same time, the inventors found that the current punching device used for bone plates often requires manual positioning, resulting in poor accuracy of the punching position and uneven quality of the bone plate.

[0045] Based on the above problems, the inventor adopted a split plate body after research, and adjusted the relative distance between the plate bodies by setting a waist-shaped through hole, so that the overall size of the bone bone plate can be adjusted, which is beneficial to improve the applicability of the bone bone plate . For the problem of drilling accuracy, the inventor adopts the method of light detection to judge whether the positioning is accurate by d...

Abstract

The invention relates to an adjustable bone fracture plate and a punching device for the bone fracture plate. The adjustable bone fracture plate comprises a first plate body, a second plate body and connecting screws; a plurality of through holes are formed in the first plate body and the second plate body; a groove is formed in the end face of one of the first plate body and the second plate body, a protruding block is arranged on the end face of the other one, and the protruding block can be inserted into the groove; a kidney-shaped through hole is formed in the side wall of one side of the groove, and a threaded fixing hole matched with the kidney-shaped through hole is formed in the protruding block; and when the protruding block is inserted into the groove, the connecting screw can penetrate through the kidney-shaped through hole to be in threaded connection with the threaded fixing hole. The punching device for the bone fracture plate comprises a conveying mechanism, a bone fracture plate fixing mechanism, a positioning mechanism and a punching mechanism. The overall size of the bone fracture plate is adjustable, so that the bone fracture plate can be suitable for more different patients and affected parts, and the application range of the bone fracture plate is widened.

Description

technical field [0001] The present application relates to the technical field of bone plates, in particular to an adjustable bone plate and a punching device for the bone plate. Background technique [0002] Bone plates are a class of medical devices used to fix fractures, and are usually used in conjunction with bone screws in clinical practice. When in use, the bone plate is usually positioned on the affected part of the bone first, and then a hole is drilled on the bone and the bone screw passes through the locking hole or pressure hole set on the bone plate and then screwed into the bone to realize the connection between the bone plate and the bone . [0003] At present, in the related art, the osteosynthesis plate is usually a metal long plate with several through holes (locking holes or pressurization holes), and some bends are made at the front end according to the difference of the affected part to fit the bone better. The length of the bone plate and the position ...
