Novel nail extractor for orthopedics department

Abstract

The invention discloses a novel nail extractor for the orthopedics department, and belongs to the technical field of medical instruments. Symmetrical chutes are formed on the surface of a supporting plate; one surface of the supporting plate is in sliding connection with a supporting rod; one end of the supporting rod is fixedly connected with a bottom plate; the center of the supporting plate is fixedly sleeved with a positioning pipe; a sliding hole is formed in the middle of the positioning pipe; one end of the sliding hole is fixedly sleeved with a bearing; an inner ring of the bearing is fixedly sleeved with a threaded rod; one end of the threaded rod is fixedly connected with a motor; the other end of the threaded rod is in threaded connection with a nail pulling rod; and the surface of one end of the nail pulling rod is fixedly sleeved with a sliding block. According to the novel nail extractor for the orthopedics department, a chuck can be rapidly helped to clamp one end of a bone nail through an arranged adjusting sleeve, and the bone nail is rapidly and stably pulled out upwards through the threaded rod, so that the nail pulling efficiency is greatly improved; and in addition, the arranged supporting rod of which the height and the horizontal position are adjustable can ensure the nail pulling stability of the nail extractor so as to avoid the case of nail breakage.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, relates to a novel orthopedic nail remover. Background technique [0002] Screw internal fixation is one of the main surgical methods in the treatment of fractures. This kind of internal fixation is widely used in clinical orthopedic surgery, and has the advantages of firm fixation, convenient operation, and good promotion of fracture healing. [0003] At present, in orthopedic surgery, it is necessary to use a nail remover to remove the bone nail from the healed patient, but the existing nail remover is not only difficult to fix one end of the bone nail during the nail pulling process, but also has low efficiency in pulling out the nail. , and in the process of pulling out the nails, since most of the nail removers do not have a stable auxiliary support, it is also more prone to breakage of the nail, which may also cause the patient to fracture again. Therefor...
