Abstract

The invention discloses an orthopaedics department hole drilling sighting device, and relates to a drill bit guide surgical operation tool used for treating limb fracture operations. The orthopaedics department hole drilling sighting device is characterized by comprising an orthopaedics department hole drilling sighting device sleeve, an orthopaedics department hole drilling sighting device rod and an orthopaedics department hole drilling sighting device handle; a sighting incline hole is formed in the orthopaedics department hole drilling sighting device sleeve, the clinic sighting angle can be conveniently selected in the operations, marble holes are formed in one side of the orthopaedics department hole drilling sighting device sleeve, and a marble and a compression spring are installed; a conic through hole is formed in the middle of the orthopaedics department hole drilling sighting device rod, and angle adjustment is carried out through the conic through hole in the operation process; a marble groove is formed in one end of the orthopaedics department hole drilling sighting device rod, so that the marble in the orthopaedics department hole drilling sighting device sleeve is conveniently clamped into the marble groove; conic threads are arranged at the head of the orthopaedics department hole drilling sighting device rod and are in fit with threaded holes in an internal fracture fixation steel plate.

Description

technical field [0001] The orthopedic drilling aimer of the invention relates to one of the surgical tools used for drill guiding in the treatment of fractures of extremities. Background technique [0002] Human extremity fractures are one of the most common clinical manifestations of orthopedic trauma. Internal fixation of fractures is a comprehensive treatment based on restoration of anatomical relationship, stable fixation, preservation of bone blood supply as much as possible, and early functional activities. [0003] The drill collimator is one of the surgical tools in internal fixation of fractures, and it is mainly used to establish the screw channel and determine the screw driving direction. Traditional drill sights can only be positioned at a single angle, and cannot be aimed at any angle. Therefore, the operation has high limitations and cannot meet the requirements of clinical operations. [0004] In recent years, bone health issues have attracted attention. The...
