Abstract
The utility model pertains to a bone connecting tractor which is matched with a broken bone connecting coater for use. The structure is a fixed screw rod which is composed of two sections, the threads which are arranged on the two sections have reverse rotation directions; the outside of the fixed screw rod is connected by the thread of a screw sleeve; and the two sides of the screw sleeve are provided with threads which are matched with the two sides of the fixed screw rod. Both ends of the fixed screw rod are fixedly provided fixed bodies; when in use, the utility model can be fixedly connected with the broken bone connecting coater. The utility model has the advantages of reasonable structure, simple and easy operation, convenient operation and unique therapeutic effect; when in use, both ends of the fixed screw rod are fixed to the broken bone connecting coater, the mechanics is taken as the power, the broken bone connecting coater is taken as the carrier, the parts of the human body are taken as the points of application of force, the tractive length can be tracted to the ideal standard easily by the connection, rotation of the screw rod and going forward gradually; the utility model thoroughly breaks through the traditional bone connecting methods and uses the mechanics to replace all the manual tractions for bone connection, so the utility model can complete the vertical traction, positioning, transverse pressure application and bone connection. The utility model can be used for the fracture treatment of all the parts of the whole body.
Description
Technical field
This utility model belongs to a kind of medical apparatus, particularly with the matching used synthetism traction apparatus of reduction of fracture device.
Background technology
After the fracture, synthetism connects fine or notly, and the operation of traction is very crucial; Have only traction well, synthetism could steady jail.In the fracture medical treatment, common way is at present, makes a call to a hole on the bone of fracture, puts on nail, is the force with the nail, hangs a weight and draws.This therapeutic modality makes the patient feel very painful, uses also very inconveniently, and the bad adjustment of weight of heavy directly influences the treatment of synthetism.
Summary of the invention
This utility model is to overcome the shortcoming that above-mentioned prior art exists, and a kind of synthetism traction apparatus is provided.Its structure is, standing screw is made up of for 4 two sections screw rod 2 and screw rod, and the screw thread rotation direction that has on two sections is opposite; Standing screw is outer to be threaded by screw shell 5; The screw shell both sides have the screw thread that cooperates with the standing screw both sides.
The standing screw two ends can be fixed with fixed body 1; Have screw on the fixed body, fixedly connected with screw 6.During use, can be connected supporting use with reduction of fracture device 7
This utility model is rational in infrastructure, and is simple, easy to operate, the therapeutic effect uniqueness during use, is fixed on the standing screw two ends on the reduction of fracture device 7 by screw 6, use supporting with it, can thoroughly break through traditional synthetism technology, replace all manual traction synthetism, can accomplish vertically can draw, can locate with apparatus, laterally can exert pressure, can synthetism, and making above-mentioned every combining together, treatment simultaneously finally reaches and accomplishs without any letup.This utility model is power with machinery, is carrier with the reduction of fracture device, is the force with the human body self position, and by connecting, rotary screw follows progressively, just can easy to do length traction be drawn to ideal standard.After treating that the synthetism program is complete, can be at that time with its dismounting.Use this utility model, need not on bone, take the least important seat at a square table again nail and the hanging of use sliding weight of steelyard, patient can significantly reduce the misery of bringing owing to nailing.This utility model can be used for the fractures at each position of whole body.
