Orthopedic drilling positioning device

Abstract

The invention discloses an orthopedic drilling positioning device; one end of a positioning rod extends into a patient body and is hinged to a positioning head with an orientation hole; one end, located outside the patient body, of the positioning rod is provided with a driving block which drives the positioning head to rotate through a guide wire; the positioning rod is also fitted with a fixed seat and a moving seat; the fixed seat is provided with an arc-shaped fixed guide rail which centers on the circle center of the orientation hole of the positioning head; a guide seat moving along thefixed guide rail is arranged on the fixed seat; an arc-shaped moving guide rail and a guide seat which can move along the moving guide rail and can freely rotate are arranged on the moving seat; eachof the two guide seats is also provided with an orientation hole; a drill rod passes through the three orientation holes to abut against the bones of the patient. The orthopedic drilling positioning device is extremely simple in structure, but can accurately position the drill rod, is simple and convenient to operate, helps effectively reduce surgical difficulty and learning cost and improve positioning accuracy and surgical treatment effect, and is also good for popularization of treatment surgeries.

Description

technical field

[0001] The invention relates to a medical device, in particular to a positioning device for assisting drilling in orthopedic surgery. Background technique

[0002] When the patient's bone is damaged and surgical treatment is required, in addition to the positioning and fixation of the bone, drilling operations are often required. For example, the shoulder joint of the human body is the joint position with the largest range of motion in the human body, and its dislocation accounts for more than 40% of the joint dislocations in the whole body; and as the frequency of anterior dislocation of the shoulder joint increases, the injury of the anterior and inferior labrum of the glenoid is often accompanied by different symptoms. degree of bone loss. The existing total arthroscopic Bristow-Latarjet operation is a main treatment method, and its main operation process includes: coracoid process exposure, coracoid process preparation, coracoid process drilling and oste...
