Children epiphyseal plate bone bridge removing device

Abstract

The invention provides a child epiphyseal plate bone bridge removing device, and belongs to the technical field of medical orthopedic tools. Comprising an outer shell, a grinding mechanism, an air suction mechanism and a scraping mechanism. The air suction mechanism comprises a first air suction unit and a second air suction unit, the first air suction unit comprises two first fixing plates fixedly installed on the inner wall of the outer shell, and the sides, close to each other, of the two first fixing plates are fixedly connected with a double-shaft servo motor; the output end of one side of the double-shaft servo motor is fixedly connected with a first rotating shaft, and the other end of the first rotating shaft is fixedly connected with a first friction table. According to the device, cancellous bones can be ground to form a tunnel leading to a bone bridge, bone scraps generated in the friction process can be sucked, manual treatment of the bone scraps is avoided, the operation efficiency is improved, meanwhile, the bone scraps generated in the bone bridge scraping process can be sucked, and normal epiphyseal plate cartilages which are not closed are prevented from being damaged when the bone scraps are cleaned.

Description

technical field [0001] The invention relates to the technical field of medical orthopedic tools, in particular to a device for removing bone bridges for children's epiphysis. Background technique [0002] The epiphyseal plate is the active cartilage area between the epiphysis and the metaphysis of children, which has the function of longitudinal and lateral growth. Fractures, infections, tumors, and radiation can all cause damage to the epiphyseal plate. The cartilage area between them forms a bony connection, that is, a bone bridge, so that all or part of the epiphyseal plate is closed in advance, resulting in limb shortening and / or angular deformity. Bone bridge resection is an alternative and effective method. [0003] However, when removing the epiphyseal plate bone bridge in children, too many medical orthopedic tools need to be used, which reduces the surgical efficiency of the doctor performing bone bridge resection, and the bone debris generated during the grinding ...
