Embodiment 1

[0032] Such as figure 1 , 2 As shown, the shoulder joint scapular bone positioning device of the present example includes: positioning rod 1 and Kirschner wire sleeve 2; The second section 12, the first section 11 has a cylindrical structure 111 with a through hole, the cylindrical structure 111 of the first section 11 is configured to hold the Kirschner wire sheath cylinder 2, the second segment 12 is a long strip-shaped positioning arm extending straight from the first segment 11, and a positioning hook 121 is provided at the end of the second segment 12; The through hole of one segment 11 is directly opposite to the positioning hook 121 , thereby forming a glenoid bone positioning space between the first segment 11 and the positioning hook 121 . During use, the positioning device is placed on the side of the target position of the glenoid bone, the positioning hook 121 is used to hook the side edge of the glenoid bone, and the Kirschner wire sleeve 2 is placed on the firs...

Abstract

The invention discloses a shoulder joint scapula glenoid bone positioning device. The shoulder joint scapula glenoid bone positioning device comprises a positioning rod and a Kirschner wire sleeve, wherein the positioning rod comprises a first cylindrical segment with a through hole and a second segment, the first segment is used for sleeving the Kirschner wire sleeve, the second segment is an elongated positioning arm extending from the first segment linearly, a positioning hook is arranged at the end of the second segment, and the through hole of the first segment is over against the positioning hook, so that a scapula glenoid bone positioning space is formed between the first segment and the positioning hook. The shoulder joint scapula glenoid bone positioning device solves the problem that shoulder arthroscopy surgery is prone to causing scapula glenoid tunnel positioning inaccuracy and tunnel establishment blindness.

Description

technical field [0001] The invention relates to the field of orthopedic surgical instruments, in particular to a shoulder joint positioning device. Background technique [0002] The shoulder joint is the complex joint with the largest range of motion among the large joints of the human body. It consists of 3 bones (clavicle, scapula and humerus), 4 joints (acromioclavicular joint, sternoclavicular joint, scapulothoracic joint and glenohumeral joint) and connecting them. Composed of muscles, tendons, and ligaments. Under normal circumstances, the four joints of the shoulder move synchronously to ensure the smooth and coordinated movement of the upper limbs. [0003] Among them, the glenohumeral joint is the joint with the largest range of motion in the human body and the smallest bony constraints. It is a ball (humeral head) socket (scapular glenoid) joint. The "ball" (humeral head) is relatively large and the "socket" (glenoid) is relatively shallow, similar to golf on a t...
