Embodiment Construction

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

[0044] At present, the size of the bone plate is usually fixed, and the adaptability to the affected area of ​​different body types and different conditions is poor. At the same time, the inventors found that the punching device currently used for the bone plate often requires manual positioning, resulting in poor punching position accuracy and uneven quality of the bone plate.

[0045] Based on the above problems, the inventors have studied and adopted a split plate body, and adjusted the relative distance between the plates by setting a waist-shaped through hole, so that the overall size of the bone plate can be adjusted, which is beneficial to improve the applicability of the bone plate. . As for the problem of punching accuracy, the inventor adopts a light detection method to judge whether the positioning is accurate by detecting whether ...

Abstract

The present application relates to an adjustable bone plate and a drilling device for the bone plate; the adjustable bone plate includes a first plate body, a second plate body and connecting screws; both the first plate body and the second plate body are A number of through holes are provided; a groove is provided on the end surface of one of the first plate body and the second plate body, and a protrusion is provided on the other end surface, and the protrusion can be inserted into the groove; one of the grooves The side wall is provided with a waist-shaped through hole, and the protrusion is provided with a threaded fixing hole matching the waist-shaped through hole; when the protrusion is inserted into the groove, the connecting screw can pass through the waist-shaped through hole and The threaded fixing holes are connected by threads. The punching device for the bone plate includes a transmission mechanism, a bone plate fixing mechanism, a positioning mechanism and a punching mechanism. The present application makes the overall size of the bone plate adjustable, so that it can be applied to more different patients and affected areas, and expands the scope of application of the bone plate of the present application.

Description

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