Embodiment Construction

[0010] Below, the substantive features and advantages of the present invention will be further described in conjunction with examples, but the present invention is not limited to the listed examples.

[0011] see figure 1 As shown, the figure shows the structure of a drill sleeve provided by the embodiment of the present invention. For ease of description, only parts related to the embodiments of the present invention are shown.

[0012] see figure 1 , a drill sleeve, mainly used for medical bone drilling, including a drill sleeve body 1, the front end of the drill sleeve body 1 has a trapezoidal guide part 2 when viewed from the front, the outer surface of the guide part 2 The outer thread matched with the locking hole on the bone fixation plate is provided on the surface, and the shape of the guide part 2 is adapted to the hole shape of the locking hole on the bone fixation plate.

[0013] Further, the other end of the drill sleeve body 1 is provided with a convenient tig...

Abstract

The invention belongs to the technical field of medical instruments and particularly relates to a drill bush. The drill bush comprises a drill bush body, a trapezoidal guide portion is arranged at the front end of the drill bush body in front view, an external thread matched with a locking hole in a bone joining fixing plate is arranged on the outer surface of the guide portion, the guide portion is matched with the locking hole in the bone joining fixing plate in shape, and an operation portion facilitating use of a tightening device is arranged at the other end of the drill bush body. The drill bush has the advantages that through the technical characteristics, drilling can be facilitated; since the guide portion is matched with the locking hole in the fixing plate and provided with the external thread, drilling accuracy can be guaranteed and medical operation level is improved.

Description

technical field [0001] The invention belongs to the technical field of medical instruments, and in particular relates to a drill sleeve. Background technique [0002] When the medical operation operation needs to fix the damaged bone of the fracture patient by locking the fixing plate, firstly, the bone will be punched, and then the screw will be implanted. In order to make a good hole on the bone and make the position of the hole meet the requirements, the drill sleeve is installed on the clamp body to determine the position of the hole to be processed on the workpiece, guide the tool to process, and improve the rigidity and stability of the tool during processing. Prevent vibration during processing. Since punching a hole in a bone is not the same as punching a hole in an object, current conventional drill sleeves cannot be used. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned technical problems and provide a dril...
