Abstract

The invention relates to a humerus positioning machine and a humerus positioning system. The humerus positioning machine comprises a main rod, a front end structure, a positioning structure, a grasping and holding rod, a swinging rod structure and a guiding structure, wherein the front end structure is in pivoting connection with the front end of the main rod; a through hole is formed in the frontend structure; the positioning structure is in pivoting connection with the main rod and the front end structure, and the positioning structure and the front end structure are arranged side by side;the grasping and holding rod is in pivoting connection with the positioning structure; the swinging rod structure is in pivoting connection with the main rod and the grasping and holding rod; the guiding structure is in pivoting connection with the swinging rod structure; the guiding structure is hollow; one end of the guiding structure is adjacent to the through hole; and the guiding structure isaligned to the center of the through hole. According to the humerus positioning machine disclosed by the invention, the main rod, the front end structure, the positioning structure, the grasping andholding rod and the swinging rod structure are arranged to form a polygonal framework; and the grasping and holding rod is pushed, so that the front end structure, the positioning structure and the swinging rod structure can be driven to rotate relative to the main rod, the inclined angle between the front end structure and the main rod, the inclined angle between the positioning structure and themain rod and the inclined angle between the swinging rod structure and the main rod are adjusted, and the humerus positioning machine can move between an initial state and an extruding state.

Description

technical field [0001] The invention relates to a scheme for arthroscopic treatment of rotator cuff tear, in particular to a humerus locator with preset sutures in the rotator cuff suture method of minimally invasive subosseous sutures. Background technique [0002] Against the backdrop of the gradual increase in the proportion of the elderly population in my country, rotator cuff injuries are a common geriatric disease. Foreign literature has reported that more than 50% of the elderly over 60 years old have partial-thickness or full-thickness tears of the rotator cuff. . Although asymptomatic rotator cuff tears do not require surgical treatment, patients with symptoms that cannot be relieved by conservative treatment still need rotator cuff suture repair surgery to solve the problem. At present, most of the rotator cuff repairs are sutured with threaded anchors in China. As more clinicians gradually understand rotator cuff injuries, the number of operations is gradually inc...
