This utility model provides a leg fracture traction device, relating to the field of leg fracture traction devices. The utility model includes a base plate, with a traction device mounted on one side of the base plate. By setting up a traction mechanism, when performing traction treatment on a fracture patient, the injured leg can be fixed to a slide and a fixation frame using a fixing component. Then, according to treatment needs, a self-locking motor is activated to drive a threaded rod to rotate, thereby causing a screw hole block to slide to one end on the inner wall of the base plate. Then, under the pull of a first telescopic rod and a first spring, the slide can move to one end within the inner wall of the base plate. The first spring and the first telescopic rod act as a buffer between the slide and the screw hole frame, preventing excessive traction caused by the screw hole block moving too quickly. This allows the slide to provide flexible traction according to actual usage during the traction process, avoiding secondary injury and improving treatment efficiency.

This utility model discloses a femoral fracture traction device, including a frame assembly, which includes a base that is movable, and symmetrical uprights on the base near the rear. It also includes a crossbeam, a support assembly, and a lifting assembly. Two sets of crossbeams are respectively hinged to the bottom ends of the handles. Each crossbeam has a fixing block at the end furthest from the handrail, which can be secured to the bed handrail. The lifting assembly includes a rotating rod rotatably mounted on a top plate, with steel cables wound around both ends of the rod. The lower ends of the steel cables are connected to the corresponding ends of the bone screws. This utility model offers high stability; and through the electrically retractable steel cables, the suspension height can be freely adjusted without frequent replacement of counterweights, making operation simple and convenient.

This utility model relates to the field of orthopedic surgical auxiliary instruments, and more particularly to an L-shaped arm fixation device for intertrochanteric fracture traction bed surgery, comprising a positioning rod and a support plate; a support plate for supporting the arm is installed on the outer side of the positioning rod, and a C-shaped clamp for engaging and limiting the position with the headboard is installed at one end of the positioning rod and the support plate; a rubber pad is installed inside the upper end of the support plate, and a grid plate is provided above the rubber pad at the upper end of the support plate; a connecting rod for telescopic adjustment of the position of the support plate is installed inside the positioning rod. This utility model achieves an L-shaped fixation structure by connecting the support plate and the positioning rod with the connecting rod, which is ergonomic and effectively avoids compression of the brachial plexus and ulnar nerve, reduces discomfort such as pain and numbness, and lowers the risk of nerve damage. Furthermore, the use of magnetic buckles to connect the ligaments ensures a clear surgical field, facilitates surgical operation, and improves the safety and precision of the surgery.

The present application relates to the field of orthopedic treatment apparatus, more particularly, it relates to multi-dimensional angle adjustable fracture three-dimensional reduction traction device, including leg support mechanism, for supporting patient's shank while fixing knee end; traction mechanism, for traction patient's heel; support mechanism, for the installation of leg support mechanism and traction mechanism; The support mechanism includes two groups of telescopic support assembly for mounting on the hospital bed, further includes the first cross bar and the second cross bar arranged between the two groups telescopic support assembly, and the locking assembly arranged on the telescopic support assembly; The locking assembly includes the locking piece arranged on the telescopic support assembly and the anti-falling fine adjustment piece arranged on the locking piece; The leg support mechanism is slidably installed on the first cross bar, and the present application solves the problem that the existing multi-dimensional angle fracture traction device is complicated to adjust, the patient's adaptability is poor and the stability of the adjustment is insufficient, which leads to accidental movement or falling.
