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 invention discloses a leg fracture positioning and orthotic device, belonging to the technical field of leg orthotic devices. It includes an orthotic component comprising a thigh fixation bracket with a lower leg fixation bracket hinged below it. A strap buckle is provided on one side of the thigh fixation bracket, and fixation holes are provided on the thigh fixation bracket and the lower leg fixation bracket. An adjustment component includes an adjustment element located on one side of the thigh fixation bracket. The advantages of this invention are: the orthotic component alone provides bed rest fixation and protection, and the bracket component can be quickly assembled to provide support for walking. The weight of the affected limb is supported by the supporting leg and foot, avoiding secondary injury to the lower leg. Switching between the two modes is convenient, adapting to the entire rehabilitation process for fracture patients.

The utility model discloses an orthopedic leg fracture support device, which relates to the technical field of orthopedic auxiliary instruments, and comprises a bottom plate, the upper end of the bottom plate is fixedly connected with a lifting device, the upper end of the lifting device is movably connected with two translation devices, and the upper ends of the translation devices are fixedly connected with telescopic devices. And an angle adjusting device is arranged between the telescopic device and the translation device. A fixing column is manually pressed, so that the fixing column extrudes a telescopic spring and retracts into a telescopic groove, the fixing column is separated from a fixing hole, a telescopic rod moves in the fixing rod, a telescopic plate is driven to move, and the telescopic plate moves along a limiting rod; when the support composed of the adjusting plate and the telescopic plate is suitable for the leg length of the patient, the fixing columns are loosened, the fixing columns are inserted into the fixing holes under the action of the telescopic springs, the length of the fracture support is adjusted, the support can be suitable for patients of different heights, and the practicability of the device is improved.

The utility model relates to the technical field of medical first aid, in particular to a leg fracture fixing splint which comprises a splint body, a rotating assembly is arranged between bent portions of the two splint bodies, fixing blocks are arranged on the side walls, away from each other, of the two splint bodies at intervals, and long bandages are symmetrically arranged on the fixing block of one splint body up and down. Short bandages are symmetrically arranged on the fixing block of the other splint up and down, and square sleeves are arranged on the short bandages. The device is simple in structure and convenient for medical staff to quickly operate on an emergency site. By means of the simple steps of pulling the pull rod, rotating the clamping plates, loosening the pull rod and the like, the legs can be rapidly clamped and fixed through the two clamping plates, the device is provided with the air bag and the convertible connector, and therefore medical staff can adjust the clamping area at any time according to the leg injury condition.

The application provides an adjustable surgical operating bed and belongs to the field of surgical operating beds, which comprises a base unit, an adjusting unit for adjusting the bed to adapt to the lifting height of leg fracture, the adjusting unit being arranged on the top of the base unit, a bed body for lifting upward to abut against the back of a patient, the bed body being movably arranged on the top of the adjusting unit, and a suspension unit for lifting the legs of the patient, the suspension unit being arranged on the top of the bed body. The primary winding wheel on the rotating shaft rotates synchronously to release the front moving rope on one side of the vertical frame, and the rotating shaft is also matched with the lifting wheel, the linkage and the linkage wheel to drive the linkage shaft to rotate and synchronously control the secondary winding wheel to rotate and release the rope, so that the constraint of the lifting belt is released, the lifting belt slowly descends when the upper bed plate is lifted, and the secondary damage to the lifted fractured leg caused by the pushing during the change of lying posture is reduced.
