Description

Fracture restorer

Technical Field

The disclosed embodiments of the present invention relate generally to the field of medical devices and, more particularly, to a fracture reducer.

Background

Fractures can be caused by trauma and bone diseases, fractures are easy to occur to children and old people due to accidents, and fractures are easy to occur to some physical workers and athletes due to long-term stress. The fracture treatment is mainly through operation incision reduction treatment, and the soft tissue at the operation incision fracture position promptly exposes the fracture end, resets through similar three-jaw fixer with the fracture under looking directly, and effective internal fixation in back can make patient's activity of getting out of the bed in advance, reduces muscular atrophy and joint stiffness, can also make things convenient for the nursing, reduces the complication. Such surgical treatment methods generally involve cutting and stripping a large range of soft tissues and periosteum, which causes great trauma and pain to patients. Due to extensive exfoliation, tissue repair results in the formation of large amounts of fibrous and scar tissue, and even cartilage or bone tissue can produce myositis ossificans, which can severely lead to joint dysfunction, and post-care can be cumbersome.

Therefore, the utility model aims to research and improve the fracture restorer which is convenient and quick to operate, flexible and simple, can be completed by one person, has limited incision and partial tissue stripping, has small wound, less pain and quick recovery, is beneficial to subsequent nursing and reduces the discomfort of a patient.

And a threaded hole matched with the positioning screw is arranged on the other side of the limiting steel plate, which is not provided with the limiting hole, and the positioning screw is screwed in the threaded hole and fixed on the backbone.

The utility model has the advantages that:

(1) the utility model is suitable for fracture reduction, has convenient and quick operation, is flexible and simple, can be completed by one person, has limited incision and partial tissue stripping, has small wound, less pain and quick recovery, is beneficial to subsequent nursing, and reduces the discomfort of patients.

(2) The utility model replaces the traditional fracture three-jaw fixator to be applied to fracture reduction, and the subsequent fixation and recovery can be facilitated after the fracture three-jaw fixator is reduced. The stable fixation of the subsequent resetting operation is ensured by placing the limiting steel plates extending to the two ends of the fracture at the fracture part and fixing the limiting steel plates through the positioning screws at one sides of the limiting steel plates. The cylindrical sleeve and the long rod drill bit which are screwed through the internal and external threads form a resetting mechanism, the long rod drill bit is fixed on the limiting steel plate after being drilled into the backbone to be reset, and the long rod drill bit is rotated to move upwards so as to lift the fracture end to be reset upwards, so that the resetting effect is achieved.

(3) The soft gasket is bonded on the lower surface of the cylindrical sleeve, so that the stability of fixing the cylindrical sleeve connected with the long-rod drill bit which is suitable for alternate at different angles can be facilitated, and the connection is strengthened. Set up cyclic annular boss above the spacing hole of spacing steel sheet, and the interior circle diameter of cyclic annular boss is greater than the telescopic excircle diameter of cylinder, ensures the fixed action of the different angles of cylinder sleeve on the one hand, can prevent effectively again that cylinder sleeve from taking place too big only and causing the injury when fixed.
