When a doctor needs to pull the legs of a patient, the doctor can firstly lay the patient on a bed, then the thighs of the patient are fixed on a first mounting plate by using a thigh protector and a first bandage, the feet of the patient are fixed on a sliding plate by using a second bandage, then the doctor can rotate the rotating handles in the upper direction and the lower direction by using the positive direction to drive a threaded sleeve to move leftwards, the threaded sleeve moves leftwards and drives the lower part of a steel wire rope to move leftwards through a second connecting rod and a tension meter, pulleys on the first supporting plate and the second supporting plate guide the steel wire rope, the upper part of the steel wire rope drives a top block to move rightwards through a first connecting block, a first compression spring is compressed accordingly, the top block moves rightwards to drive the feet of the patient to move rightwards, the tension meter can display the tension force borne by the steel wire rope, and when the tension displayed on the tension meter is appropriate, the threaded sleeve stops moving leftwards, the top block stops moving rightwards, the leg of the patient can be pulled, if the force can be well controlled, the patient can be helped to recover faster, after the pulling is finished, a doctor can drive the threaded sleeve to move rightwards by rotating the upper and lower rotating handles in opposite directions, the threaded sleeve moves rightwards, the first compression spring is loosened through the steel wire rope, under the action of the first compression spring, the top block moves leftwards to reset and drives the foot of the patient to move leftwards to reset, then the doctor can assist the patient to loosen the thigh protector and the first bandage so that the thigh of the patient is not fixed on the first mounting plate, the second bandage is loosened so that the foot of the patient is not fixed on the sliding plate, the patient can put the leg down and come up and down from the bed body, and then the doctor can drive the support frame to rotate upwards by rotating the first, when the support frame upwards rotates to the lathe bed top, the doctor stops upwards rotating the head rod, then rotate the movable support board forward, make movable support board top right side no longer with head rod bottom contact, so can play the effect of accomodating, can save the space that this equipment occupy, when the doctor need carry out the shank for patient and pull, at first the doctor can rotate the head rod downwards, when the head rod rotates downwards and resets, the doctor stop rotating the head rod can, it rotates the movable support board backward to connect, make movable support board top right side contact bottom the head rod once more, play the effect of supporting the head rod.
After the doctor ties up patient's thigh on first mounting panel, the doctor can insert the second screw hole with the bolt for L shape poles are hugged closely to the bolt, reach the effect of fixed L shape pole, thereby fix patient's thigh better, when need not pull for patient, the doctor can unscrew the bolt slightly, make the bolt no longer with L shape pole contact can, so can prevent patient and disorderly when carrying out the shank and pull, influence treatment.
After a patient lies on the bed body, a doctor can enable the patient to hold the handrail by hands and then pull the legs of the patient, after the traction is finished, the doctor can rotate the handrail down, so that the patient can conveniently get on or off the bed, the patient can get on or off the bed, and before the doctor pulls the patient next time, the doctor can turn the handrail up again, so that the patient can conveniently hold the handrail in the treatment process.
When a doctor needs to adjust the traction angle of a patient, firstly, the doctor can upwards rotate the first connecting rod and the support frame, then the ratchet body anticlockwise rotates, when the support frame upwards rotates to a proper position, the doctor stops rotating the ratchet body, the ratchet body is clamped and matched with the movable ratchets again under the action of the gravity of the first connecting rod and the support frame, then, the doctor pulls the legs of the patient, when the doctor needs to reset the support frame, firstly, the doctor can leftwards move the pull rod, so that the movable ratchets leave the ratchet body, the pull rod leftwards moves to drive the guide plate to leftwards move, the second compression spring is compressed, then, the first connecting rod and the support frame downwards rotate, then, the ratchet body clockwise rotates, after the support frame downwards rotates and resets, the doctor loosens the pull rod, under the action of the second compression spring, the guide plate drives the pull rod, the movable ratchet is clamped and matched with the ratchet body again to further fix the support frame, so that a doctor can adjust the traction angle according to the condition of a patient, and the treatment effect is more remarkable.
The leg traction device has the advantages that the screw sleeve is rotated by a doctor to move leftwards, so that the feet of a patient move rightwards, the legs of the patient can be pulled, the effect of effectively stretching the legs is achieved, the doctor can accurately control the pulling force to achieve a better treatment effect by arranging the tension meter, the L-shaped rod is fixed by arranging the second threaded hole and the bolt, the effect of fixing the thighs of the patient on the first mounting plate is achieved, and the doctor can adjust the pulling angle according to the illness states of different patients by arranging the ratchet wheel body and the movable ratchet wheel, so that leg traction treatment is more effective.

After the doctor ties up patient's thigh on first mounting panel 4, the doctor can insert bolt 44 into second screw hole 43 for bolt 44 hugs closely L shape pole 5, reaches the effect of fixed L shape pole 5, thereby fixes patient's thigh better, when need not drawing for patient, the doctor can unscrew bolt 44 a little, make bolt 44 no longer with L shape pole 5 contact can, so can prevent that patient from moving about when carrying out the shank and drawing, influence treatment.
After a patient lies on the bed body 1, the doctor can hold the handrail 48 with the hands of the patient and then pull the legs of the patient, after the pulling is finished, the doctor can rotate the handrail 48 to bring convenience for the patient to go up and down, and then the patient can go up and down from the bed body 1, before the doctor pulls the patient next time, the doctor can rotate the handrail 48 to go up to hold the patient conveniently in the treatment process.
When a doctor needs to adjust the traction angle of a patient, firstly, the doctor can upwards rotate the first connecting rod 2 and the support frame 3, then the ratchet body 49 anticlockwise rotates, when the support frame 3 upwards rotates to a proper position, the doctor stops rotating the ratchet body 49, under the action of the self gravity of the first connecting rod 2 and the support frame 3, the ratchet body 49 is clamped and matched with the movable ratchet 55 again, then the doctor pulls the leg of the patient, when the doctor needs to reset the support frame 3, firstly, the doctor can leftwards move the pull rod 54, so that the movable ratchet 55 leaves the ratchet body 49, the pull rod 54 leftwards moves to drive the guide plate 52 to leftwards move, the second compression spring 53 is compressed, then downwards rotates the first connecting rod 2 and the support frame 3, then the ratchet body 49 clockwise rotates, after the support frame 3 downwards rotates to reset, the doctor releases the pull rod 54, under the action of the second compression spring 53, the guide plate 52 drives the pull rod 54 to move rightwards to reset, so that the movable ratchet 55 is clamped and matched with the ratchet wheel body 49 again, the support frame 3 is further fixed, and therefore a doctor can adjust the traction angle according to the condition of a patient, and the treatment effect is more remarkable.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
