Abstract

The invention relates to a medical slotting device for orthopedics department. The device comprises a housing, a drive frame and a drill bit assembly, wherein the drive frame is rotatably arranged inthe housing, one end of the driving frame is protruded on the top of the sleeve shell and concave with a driving groove, the drill bit assembly includes a main drill pipe and two sub drill pipes, oneend of the main drill pipe is fixed on the drive frame, and the other end protrudes from the bottom of the housing to form a slotted drill bit. The two auxiliary drill pipes are engaged with the slotted drill bit, and the ends of the two auxiliary drill pipes are formed with an auxiliary drill bit, and the diameter of the auxiliary drill bit is smaller than the diameter of the slotting drill bit.The device can effectively reduce the rotation and sliding between the osteotomy blocks.

Description

technical field [0001] The invention relates to a medical orthopedic slot opener. Background technique [0002] In orthopedic surgery, it is often necessary to use a drill bit to open a slit on the bone, that is, to drill a hole, and then use a steel wire to fix the bone. However, in the prior art, the bone slotter can only open a circular hole on the bone, and the circular hole cannot effectively reduce the rotation and slippage between the osteotomy blocks due to its special shape. Contents of the invention [0003] Based on this, it is necessary to provide a medical orthopedic slotter that can effectively reduce the rotation and slippage between osteotomy pieces. [0004] A medical orthopedic slit device, comprising a casing, a driving frame and a drill assembly, the driving frame is rotatably arranged in the casing, one end of the driving frame is protruded on the top of the casing and recessed A drive slot is formed, the drill bit assembly includes a main drill rod ...
