Child femoral shaft skin traction anti-rotation device

Abstract

The invention provides a child femoral shaft skin traction anti-rotation device, relates to the technical field of medical instruments, and solves the problems that the existing child is lack of consciousness of joint movement after a femur operation, the disconnection position is extremely easy to displace after the movement, the later healing effect is influenced, and secondary injury is causedto the child. The child femoral shaft skin traction anti-rotation device comprises a first limiting mechanism and a first adjusting mechanism, wherein the rear end of the first limiting mechanism is rotationally connected to the position above the front end of a supporting plate mechanism; and the first adjusting mechanism is rotationally connected to the middle position in the first limiting mechanism. During use, the upper end of the femoral shaft of a child is placed in the semicircular clamping groove of the fixed clamping plate A, the lower end of the femoral shaft of the child is locatedin the semicircular clamping groove of the fixed clamping plate B, then the hook claw A is connected with the extension plate of the template A in a hung mode, and the adjusting rod A is rotated; therefore, the adjusting clamping plate A and the fixing clamping plate A fix the upper end of the femoral shaft of the child.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a traction and anti-rotation device for children's femur stem skin. Background technique [0002] The femur is the longest tubular bone in the human body. The femoral shaft includes the backbone from 2 to 5 cm below the tuberosity to 2 to 5 cm above the femoral condyle. The femoral shaft is surrounded by three groups of muscles. Due to the well-developed muscles of the thigh, there are often dislocations and overlaps after fractures. The distal end of the fracture often tends to move inward, and the fracture that has been aligned often tends to bulge outward. During the treatment of fractures, care should be taken to correct and prevent it. When the lower third of the femur is fractured, because the blood vessels are located behind the femoral fracture, and the distal end of the fracture is often angled backward, it is easy to stab the popliteal artery an...
