Pedicle screw capable of being clamped unilaterally

Abstract

The invention provides a pedicle screw capable of being clamped unilaterally and belongs to the field of medical instruments. The pedicle screw comprises a main body and two side plates, the side plates are disposed on the top of the main body and used for being connected with fixing screws, grooves are formed in the outer side faces of the side plates, and the distance between the two end faces of the side plates is gradually increased in the direction from inside to outside. According to the pedicle screw capable of being clamped unilaterally, the grooves are formed in the outer side faces of the side plates so that clamping tools can be hooked into the grooves through fixing hooks to limit the side plates in clamping grooves; the spacing between the inner sides of the two end faces of the side plates is greater than that between the outer sides of the two end faces of the side plates, so that the clamping grooves of the clamping tools do not need to be provided with inner side walls; the side plates are limited in the clamping grooves through the two end faces of the side plates, and the situation that the inner side walls of the clamping grooves enter installation slots and affect installation of a fixing screw is avoided. The clamping tools can be used for clamping the pedicle screw capable of being clamped unilaterally through one side plate, blockage of the top of the pedicle screw is avoided, and subsequent operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a pedicle screw capable of unilaterally clamping. Background technique [0002] In the existing pedicle screws, the top of the main body is provided with two side plates for connecting with the fixing screws, and there is no special structure for clamping. When in use, it can only be clamped by a clamping tool similar to pliers The outer side of the two side plates of the pedicle screw, so as to install the pedicle screw, clamping the pedicle screw by this clamping method will completely cover the top of the pedicle screw, which is not conducive to the installation of the pedicle screw. Operations such as position alignment and installation of fixation screws in the installation slots of pedicle screws. Contents of the invention [0003] The purpose of the present invention is to provide a pedicle screw that can be clamped on one side to solve the probl...
