Description
Technical Field
The utility model relates to the field of medical equipment, concretely relates to femoral fracture leads out restorer.
Background
At present, when fracture is fixed in rows, the dislocation is generally pulled open by manpower and then reset, and a steel plate is fixed and clamped, so that medical workers are very labor-consuming, and pain is increased for patients, particularly, when fracture of thighbone (thigh) occurs, muscles are developed, and the muscles are strongly contracted by stimulation of pain after fracture, meanwhile, hematoma, edema and over-high tension are generated locally, so that the dislocation is not easy to pull open, the operation time is prolonged frequently, and the amount of bleeding is large; meanwhile, the alignment is not ideal due to insufficient retraction; even if the bone is aligned, the fixation effect is poor, slight dislocation is easy to occur during drilling, the upper clamping jaw and the lower clamping jaw are adopted for clamping the fracture part, the muscles around the bone are required to be completely stripped, the injury is large, the bone forceps and the fixator are used for fixing after the bone is aligned, time and labor are wasted, and the pain of a patient is great.
Retrieving a published application number 93210836.9, the bone fracture retractor and repositor is disclosed, which consists of a frame, a screw rod, a fixed block and a clamp holder part; the double-clamp is adopted, the upper part of the double-clamp is respectively arranged on a screw rod with left-hand and right-hand threads between frames, the middle part of the double-clamp is a knurled round sleeve with a cavity with screw holes at the upper part and the lower part, the left clamping jaw and the right clamping jaw are arranged at the lower part of the double-clamp and combined into a circular arc shape, the upper part, the lower part and the transposition position of the clamping jaws are adjusted by upper and lower flat nuts, and the manpower is replaced by machinery. However, after the dislocation axis is pulled upwards, there is a distance between the two bone segments in the transverse direction, and since the holder cannot swing left and right, the adjustment is not good during the alignment, and there is a possibility of secondary damage during the pulling process or the alignment.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a femoral fracture retractor repositor which is used for retracting and conveniently aligning fractures in a dislocation way.
Realize the utility model discloses the technical solution of purpose does: femoral fracture leads out restorer, include the frame, have the screw rod of levogyration screw thread section and dextrorotation screw thread section and two holder subassemblies, the screw rod stretches out from the both ends of frame, the one end of screw rod is equipped with the hand wheel of rotatable screw rod, its characterized in that: the clamp holder assembly comprises a sliding block, a swinging rod, a movable clamping jaw and a fixed clamping jaw, wherein the sliding block is in sliding fit with the frame, the fixed clamping jaw is provided with a threaded rod, the sliding block is provided with a screw hole matched with a left-handed thread section or a right-handed thread section, one end of the swinging rod is hinged with the sliding block, the other end of the swinging rod is provided with a threaded hole matched with the threaded rod, and the movable clamping jaw is detachably connected with the fixed clamping jaw.
