A type of orthosis for fracture patients

Abstract

This invention relates to the field of medical assistive rehabilitation equipment technology, specifically an orthosis for fracture patients. It includes a bed frame, a traction frame mounted on the bed frame, and a protective shell mounted on the side of the bed frame. A square frame is movably positioned between the bed frame and the traction frame. An exercise ring is mounted on the bed frame, and a traction switching unit is mounted on the traction frame. Furthermore, it does not interfere with upper limb rehabilitation exercises during leg rehabilitation orthotics. A traction adjustment component, also mounted on the bed frame, provides traction support for patient rehabilitation and allows for adjustment of the traction force. This orthosis for fracture patients, through the inclusion of an exercise ring, allows patients to easily pull with a force less than their own strength for exercise. This gradually increasing traction design better adapts to the needs of different patients, allowing for gradual adjustment of the traction force, enabling finer adjustments, and is more convenient than existing methods that involve adding weights.

[0053] The end face of the main air pipe is provided with a hose, the other end of the hose is provided with an air cylinder, the air cylinder is arranged on the bed body, a rotating column is movably arranged in the air cylinder, a piston disc II is movably arranged in the air cylinder, a threaded groove is formed in the bottom end of the rotating column, a threaded rod is rotatably arranged at the top end of the piston disc II, the threaded rod is threadedly connected in the threaded groove, a guide groove is formed in the bottom end of the rotating column, and two guide rods are arranged at the top end of the air cylinder and movably arranged in the corresponding guide grooves; the threaded groove in the rotating column drives the threaded rod to ascend and descend, thereby extruding and pulling the piston disc II to increase or decrease the gas in the air cylinder, so that the amount of gas in the main air pipe is controlled through the hose.

[0054] When the device is used, first, when the lower limbs need to be exercised, the user holds the exercise ring 4 tightly with both hands, the exercise ring 4 is pulled, the pull rope 614 moves, the pull rope 614 drives the rotating wheel 613 on the inner side to rotate, the rotating wheel 613 drives the light rod 611 arranged in the inner side to rotate, the light rod 611 drives the support rod 618 on the end face to rotate, the support rod 618 drives the clamping block 622 on the outer surface to rotate, and since the clamping block 622 is arranged in the clamping groove 623 formed in the end face of the first straight cylinder 619, the first straight cylinder 619 drives the pulley 67 to rotate, thereby driving the exercise rope 62 arranged in a winding mode on the outer surface to move, the exercise rope 62 passes through the pulley rod 64 to drive the belt ring 65 to move, thereby exercising the lower limbs of the patient.

[0055] When only the lower limbs need to be exercised, the square frame 3 can be pulled, which drives the switching rope 612 to move, and the switching rope 612 drives the inner switching wheel 69 to rotate, which drives the inner inclined groove 615 to rotate, and the inclined rod 616 is arranged in the inclined groove 615, so that the connecting rod 617 can be moved, and the connecting rod 617 drives the clamping block 622 on the outer surface of the supporting rod 618 to move, so that the clamping block 622 moves from the clamping groove 623 in the end face of the first straight cylinder 619 to the clamping groove 623 in the end face of the second straight cylinder 620. At the same time, when the switching wheel 69 is rotated, the straight plate 610 on the end face is rotated on the end face of the traction frame 2, so that the iron ball 83 is extruded in the circular groove one 82, and the iron ball 83 extrudes the lifting plate 84 to move in the sleeve plate 85, and at the same time extrudes the spring one 86 to deform. At this time, in the process of rotating, the iron ball 83 is driven to slide in the U-shaped groove 81, so that the iron ball 83 moves into the circular groove two 810, and at the same time the spring one 86 resets, drives the lifting plate 84 to move, so that the iron ball 83 is clamped in the circular groove two 810. Therefore, when the exercise ring 4 is pulled, the rotating wheel 613 is driven to rotate through the pull rope 614, and the rotating wheel 613 drives the pulley two 68 to rotate at this time, so as to drive the lifting rope 63 to move. The lifting rope 63 enters the protective shell 5 through the pulley rod one 64 and the pulley rod two 66. Since the lifting rope 63 is arranged on the end face of the connecting column 710, it can be deformed when pulled, which can improve the pulling force, so as to achieve the exercise effect. When it needs to be reset, the square frame 3 can be pulled again to drive the switching wheel 69 to rotate, so that the iron ball 83 slides in the arc-shaped groove 89, so as to pass through the U-shaped groove 81. At this time, the spring two 87 is deformed, and then the square frame 3 is released. The spring two 87 drives the lifting plate 84 and the iron ball 83 to move into the circular groove one 82, and is reset to the initial position.

[0056] When the orthosis needs to be pulled, the belt ring 65 can be put on the patient's foot, and the traction force is generated by the elastic traction rope 625 and the strong tension spring 78. When the upper limbs are exercised, the lifting rope 63 drives the pulley rod two 66 to rotate, and at the same time drives the elastic traction rope 625 to rotate. However, since the elastic traction rope 625 is elastic, it can slowly reset, but there is no significant reduction in pulling force.

[0057] When the pulling force needs to be adjusted, the rotating column 711 can drive the threaded groove 716 to move, and since the guide rod 713 on the end face of the piston disc two 714 and the guide groove 712 at the bottom end of the rotating column 711 are arranged, the piston disc two 714 can drive the gas in the air cylinder 74, the gas in the main air pipe 73 through the hose 72, and the piston disc one 75 in the connecting cylinder 71 through the main air pipe 73. Descend, so that the strong tension spring 78 changes. When the connecting column 710 needs to be pulled again to deform the strong tension spring 78, more pulling force is needed, and vice versa.

[0058] Example 2: Please refer toFigures 13-14 The application provides a technical scheme: the outer surface of the traction frame is sleeved with two collars, the outer surfaces of the two collars are provided with side plates, the two side plates are provided with a stop lever, the outer surface of the traction frame is closely attached to the outer surface of the elastic traction rope, and the stop lever can effectively change the traction direction of the elastic traction rope, so that the patient can be pulled by horizontal tension as much as possible.
