Description
Technical field
This utility model belongs to technical field of medical instruments, the portable lower extremity surgery traction restorer that specifically the traction closed reduction is used in bone surgery.
Background technology
Fractured near end of thighbone is common wound in the orthopaedics field, and traditional treatment is: under assistant's countertraction, the fracture end open reduction is also implemented internal fixation, and this method wastes time and energy, and reduction by traction is unstable, often influences therapeutic effect; And patient trauma is big, painful big, and broken ends of fractured bone union of fracture waits slowly.
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, time saving and energy saving portable lower extremity surgery traction restorer.
The purpose of this utility model is achieved in that this portable lower extremity surgery traction restorer is made up of trocar sheath, inner sleeve, screw rod, sliding sleeve, support arm; Connect in the bearing inner sleeve of trocar sheath lower end internal fixation and fixing the screw rod that the outer end is provided with handwheel, screw front end is threaded in the upper end that adapts with the trocar sheath inner chamber in the trocar sheath and is connected with in the inner sleeve of arc holder; Above, trocar sheath slide outside suit is provided with the sliding sleeve of fastening bolt; Connect the gripper shoe that the upper end of fixing the isoceles triangle shape is provided with postive stop baffle on the sliding sleeve outer wall; Through bearing pin two the symmetrical support arms that are being rotationally connected, shoe cover is being rotationally connected respectively above the support arm on the gripper shoe of postive stop baffle below.
During use; With this device horizontal positioned and make the arc holder of inner sleeve upper end be supported in patient's pubis place, regulate the sliding sleeve position and also make patient's both feet be fixed in abduction 30 degree in back in the shoe cover, rotate handwheel then inner sleeve is slowly extended; Thereby make two lower limb isometric fixing, reach the purpose of reduction by traction.
The advantage of this utility model: simple in structure, easy and simple to handle, in reduction of the fracture process, traction is stable, and time saving and energy saving, the patient suffering is little; And disassembly and assembly are convenient, are easy to carry and receive and keep.
