Abstract

A negative pressure suction cup type humerus head taking-out device comprises a support, a negative pressure connecting pipe is arranged on the support in a penetrating mode, the negative pressure connecting pipe is sleeved with a rotary knob on the upper side of the support in a sliding mode, the rotary knob can slide in the axial direction of the negative pressure connecting pipe, a first gear is connected to the lower side of the rotary knob, and a second gear and a third gear are arranged on the rear side and the right side of the first gear respectively, the third gear is arranged below the second gear, the second gear and the third gear are fixedly connected with a first transmission rod and a second transmission rod respectively, and the lower end of the first transmission rod and the lower end of the second transmission rod are connected with a first bevel gear and a second bevel gear respectively. By means of the characteristic that the surface of the cartilage of the humerus head is smooth, adsorption of the humerus head and the device is achieved through the suction cup, artificial injury to the surrounding tissue of the shoulder joint is reduced, meanwhile, the humerus head can be completely taken out, the risk of humerus head necrosis is reduced, and postoperative rehabilitation of a patient is facilitated.

Description

technical field

[0001] The invention relates to articles for human life, in particular to a medical device, in particular to a negative pressure suction cup type humeral head extraction device. Background technique

[0002] Proximal humeral fracture with dislocation of the humeral head is a relatively common type of fracture, which involves dislocation of the humeral glenoid joint (displacement of the humeral head from the glenoid fossa), and anterior dislocation is more common than posterior dislocation. In some cases, neurovascular injury, often caused by dislocation of the humeral head, can significantly increase the risk of avascular osteonecrosis of the humeral head. In such cases, surgical treatment is required as soon as possible, especially if salvage of the humeral head is desired. Open reduction and fixation with angled stabilizing plates are currently the techniques of choice for the treatment of these fractures.

[0003] During the clinical operation, the dislo...
