Description
Technical field
This utility model belongs to technical field of medical instruments, specifically a kind of orthopaedics synthetism nail extractor.
Background technology
Synthetism steel plate, synthetism nail internal fixation are the main means of treatment fracture, treat to take out internal fixation after the union of fracture.The taking-up of the nail of synthetism at present mainly is use screwdriver, because withstanding on the power that synthetism nails on, the power of screwdriver when screwing out the synthetism nail and screwdriver be directly proportional, and therefore effort relatively just when meeting the synthetism nail that difficulty gets, the people that strength is little often is difficult to taking-up is followed closely in synthetism.Simultaneously owing to skid repeatedly, wear and tear, synthetism ailing groove is also destroyed easily, makes that the nail groove shoals, broadening, more is difficult to the synthetism nail is taken out.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy and simple to handle, can make screwdriver and synthetism clench close the combination, is convenient to the orthopaedics synthetism nail extractor that the synthetism nail is back-outed.
The purpose of this utility model is achieved in that this orthopaedics usefulness synthetism nail extractor is by sleeve, screwdriver, slide block, support spring, claw, screw rod is formed, the slip suit the screwdriver that the lower end is provided with cutter head in the centre bore of square sleeve lower surface, the screwdriver upper end is fastened on the slide block lower end that adapts with barrel bore in the sleeve, be with support spring on the screwdriver between slide block and the sleeve lower surface, the sleeve lower end is being connected and fixed bayonet socket " U " shape claw relative with screwdriver by the arc brace, the bayonet socket width of " U " shape claw greater than synthetism ailing shank diameter less than synthetism ailing head diameter; Sleeve upper end sidewall is being connected and fixed symmetrical handle, and upper surface centre bore female thread is connecting the screw rod that the upper end is provided with handwheel, and the screw rod lower end contacts with slide block in the sleeve and is connected.
During use, the synthetism nail that at first appears internal fixation, " U " shape claw with reuse sleeve pipe lower end behind the normal screws cutter back-out segment screw is stuck on the nail bar of synthetism ailing subfacies, rotate handwheel and make screw rod extruding slide block, the fixed screwdriver in slide block bottom surface can powerful be pressed in the nail groove of synthetism ailing head, holds the handle rotational sleeve then and can easily the synthetism nail be taken out.
Advantage of the present utility model: simple in structure, easy and simple to handle, between screwdriver and the synthetism nail interlock tight, rotational sleeve can take out the synthetism nail easily, and is time saving and energy saving, can alleviate patient's misery.
