Description
Technical field
The present invention relates to bone surgery set field, particularly relate to a kind of shoulder joint positioner.
Background technology
Shoulder joint is the complicated joint that in the large joint of human body, mobility is maximum, is made up of 3 pieces of bones (clavicle, scapula and humerus), 4 joints (between acromioclavicular joint, sternoclavicular joint, omoplate thoracic wall joint and Glenohumeral joint) and the muscle, tendon and the ligament that are connected them.Four joint synchronous motions of shoulder, ensure smooth and easy, the coordination of upper extremity exercise under normal circumstances.
Wherein, Glenohumeral joint is that physical activity scope is maximum, and bone retrains minimum joint, and it is a kind of ball (head of humerus) nest (Scapula glenoid) joint." ball " (head of humerus) is relatively large, and " nest " (Scapula glenoid) is relatively very shallow, this is similar to the golf on ball seat, thus makes Glenohumeral joint joint obtain maximum mobility, but this also makes shoulder be easy to injured and produces unstable.Glenohumeral joint mainly relies on the soft tissues such as circumferential cartilage, glenohumeral ligaments, shoulder sleeve and brachial biceps to obtain stability.
Shoulder Joint Injury refers to respectively organize because of shoulder comprise shoulder sleeve, ligament generation degenerative change, or because of the excessively damage of shoulder joint surrounding tissue that causes of the reason such as use, wound repeatedly, shows as shoulder pain.Common Shoulder Joint Injury has subacromial impingement disease, rotator cuff injury, congealed shoulder, brachial biceps damage, upper broad-mouthed receptacle for holding liquid lip tears (SLAP) damage from front to back, shoulder joint is unstable.
Cause the reason of Shoulder Joint Injury to mainly contain to comprise: age factor, person in middle and old age be Shoulder joint send out crowd well.Along with the age increases, shoulder is respectively organized and is comprised shoulder sleeve, ligament generation degenerative change, and its tissue elasticity is progressively lost, and becomes stiff, thus more easily injured; Repeatedly excessively using upper limb, is another common causative factors of Shoulder joint, and being especially engaged in needs repeatedly to go up movement and do the athlete that the crowd of occupation and needs mistake push work, such as baseball, vollyball, tennis and swimming; Wound: the primary paathogenic factor being youngster Shoulder joint, as the damage that vehicle accident causes.
At present, application arthrocsopic surgery treatment shoulder joint associated injury is increasingly extensive, the operation needing in a large number to set up Scapula glenoid osseous tunnel is had in arthrocsopic surgery, as the repairing of Bankart damage, the processus coracoideus transposition bone grafting of Scapula glenoid Cranial defect, the iliac bone block bone grafting of Scapula glenoid Cranial defect, the repairing of Scapula glenoid lip, fixing of Scapula glenoid front lower place avulsion bone block.But the domestic localizer for setting up Scapula glenoid osseous tunnel is still in the blank stage in design and production field at present, lack the consequence of related equipment be locate when setting up Scapula glenoid tunnel inaccurate, tunnel is set up has blindness, and due to human anatomic structure, important nerve and blood vessel is very easily damaged when setting up this tunnel, not only have a strong impact on success rate of operation, and cause the difficulty of operation and risk to increase.
Therefore, those skilled in the art is devoted to exploitation and a kind ofly can stablizes, accurately and the device setting up Scapula glenoid osseous tunnel of safety.
