Abstract
The utility model discloses a thighbone fracture reposition fixator, which is characterized in that the frame comprises a three head screw and a screw. The interspace of the three head nut is provided with an active support board. The nut with cover fixes the support board on the screw. The screw thread also has two nuts provided with thimble support board. One end of the locking needle rod is fixed on the thimble support board by the nut with the thread. The advantage is simple structure, practicability and low cost. The utility model perfectly fixes the fracture position after the thighbone fracture and reduces the occurrence of the complication. The sufferer recovers earlier.
Description
Technical field this utility model relates to orthopaedics and uses apparatus technical field, especially a kind of fracture of shaft of femur reduction fixture device.
Background technology femoral shaft (Thigh bone) fracture is general to be adopted manual reduction, small splints fixation or cuts internal fixation (comprising steel plate or intramedullary needle), and the former is often fixing not firm, produces wound and is difficult for handling; The latter is then big to tissue injury, and the medical treatment cost height also needs second operation to get steel plate and cuts both ways.The fracture of shaft of femur reduction fixture device falls between, and adopts the external fixation of threading a needle of half insertion type, more effective treatment fracture.This apparatus is mainly used in open, the unstable fractures in position such as treatment femoral shaft, knee joint.
The utility model content: the purpose of this utility model provides a kind of treatment fracture of shaft of femur external fixator, without cutting operation, makes the patient at 1-2 out-of-bed activity in week, has reduced the generation of complication, makes the fracture patient early recovery.
This apparatus adopts C type arm TV X-ray to monitor that percutaneous pinning adds external fixator fixes fracture end down, by regulating the nut on the connecting rod, by pressurization and draw, fracture end is resetted again, removes external fixator and draw point after the union of fracture.
The fracture of shaft of femur reduction fixture device is characterized in that: its support of described holder is made up of two three screw rods and a screw rod; Three screw rod one ends are fixed with three head nuts, and three head nut center fixed have movable supporting board, and the other end of three screw rods is fixed with nut with cover fixed supported slab is fixed on the screw rod; Fixed supported slab, movable supporting board are that semi-circular steel plate constitutes, jack is fixed with screw rod in the middle of the annular of semi-circular steel plate, screw rod is provided with screw thread, screw thread one end is fixed with two nuts, two nut center fixed have annular movable supporting board, the other end of screw rod is fixed with annular fixed supported slab with acorn nut, and screw flight also has two nuts to be fixed with an end of thimble support plate, and the other end of thimble support plate, fixed supported slab, movable supporting board are fixed in the purl bar circular trough by nut; Purl bar one end is threaded with nut and is fixed on thimble support plate, fixed supported slab, movable supporting board, the purl bar other end is a cylindrical bar, and cylindrical bar is provided with the spicule hole, and an end of purl cover is an open type, the other end is provided with seam and purl post coupling, and the purl cover also is provided with the spicule hole with purl post coupling.
Advantage of the present utility model is: simple in structure, and practicality, cost is low, and be applied to fracture of shaft of femur fracture site is resetted well, but and 1-2 just out-of-bed activity after week.As adopt traditional conservative treatment or cut fixing (steel plate or intramedullary needle), needing bed 2-3 month, this apparatus is exempted the hardship of patient's bed, but still will adopt the open reduction method to the open comminuted fracture of complexity.
