[0002] Traction is a commonly used treatment method in orthopedics. An orthopedic traction device is a novel instrument that uses mechanical transmission for traction. Especially for patients with lower limb fractures, appropriate lower limb traction helps their recovery.

[0003] Currently, existing lower limb traction devices are usually installed on nursing beds and mainly use the method of pulling the traction rope with the upper limb to lift and traction the lower limb of the patient. Although this method can achieve the traction effect on the patient, the position of the traction end of the traction rope is fixed, that is, the distance between the fixation point of the lower limb and the upper limb is certain. The distance between the fixation point of the lower limb and the upper limb determines the height of the user, and the heights of different users of different ages vary. The traction end of the traction rope with a fixed distance will not be applicable to patients of different heights. Summary of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figure 1-2 shown, an adjustable traction device includes a nursing bed 1. At both sides of the nursing bed 1 along its length direction, U-shaped brackets 2 are fixedly connected. A sliding seat 3 is slidably connected to the tops of the two U-shaped brackets 2. A fixed pulley 4 is fixedly connected to the sliding seat 3. A traction rope 5 is wound around the fixed pulley 4. One end of the traction rope 5 is connected to a sheath 6 for fixing the lower limbs of the patient. The other end of the traction rope 5 is fixedly connected to the head of the nursing bed 1. A handle 7 for the patient to hold with the upper limb is provided at one end of the traction rope 5 close to the head of the bed.

[0021] Wherein, under the drive of an external drive source, the sliding seat 3 can slide along the tops of the two U-shaped brackets 2, and the position of the sheath 6 is adjusted to meet the use of patients with different heights.

[0022] This device can adjust the position of the sheath in real time according to the height of the user, that is, the position of the suspension point of the patient's lower limbs can be adjusted, so as to meet the traction care of different users.

[0023] Since when the patient lies down, the position of the head is usually in a fixed position, that is, the position of the head of the bed, and the sheath 6 contacts the fractured limb of the patient, and the height of the patient determines the position of the sheath 6, so the position of the sheath needs to be adjusted at all times.

[0024] Specifically, as Figure 1-2 shown, chutes 8 are opened at the tops of the two U-shaped brackets 2. Sliders 9 are fixedly connected to the sliding seat 3 at positions corresponding to the two chutes 8. A threaded lead screw 10 is fixedly connected to the inner cavity of one of the chutes 8. The threaded lead screw 10 is threadedly connected to the slider 9. One end of the threaded lead screw 10 extending out of the chute 8 is connected to a forward and reverse motor 11. A switch for driving the forward and reverse motor 11 to rotate can be arranged on the nursing bed 1.

[0025] During use, the operator controls the movement of the sliding seat 3 through the switch. Since the fixed pulley 4 arranged in the sliding seat 3 is the stress point position of the traction rope 5, the adjustment of the position of the sliding seat 3 will also change the position of the sheath 6.

[0026] That is, the forward and reverse motor 11 drives the threaded screw 10 to rotate, and the rotating threaded screw 10 drives the slider 9 thereon to slide along the slide groove 8. Since the sliding seat 3 realizes the synchronous movement of the two ends of the sliding seat 3 through the two sliders 9 thereon, when one of the sliders 9 slides under the action of external force, the other slider 9 slides synchronously under the drive of the sliding seat 3.

[0027] Since the lifting of the sheath 6 mainly depends on the strength of the patient's hands, and the strength of the patient's two hands is obviously stronger than that of one hand, a method of lifting the sheath with both hands can be considered.

[0028] Specifically, Figure 1 As shown, the traction rope 5 is arranged in a Y-shape, and the traction rope 5 includes a main rope 51 and two branch ropes 52. The main rope 51 and the two branch ropes 52 are connected at one point. The main rope 51 is connected to the sheath 6. The two branch ropes 52 are both connected to the head of the nursing bed 1. The two branch ropes 52 are both connected to the handles 7.

[0029] Further, such as Figure 1 As shown, the handle 7 is wrapped with a sponge layer 12 to improve the comfort of the patient's grip.

[0030] As the position of the sliding seat 3 changes, the position of the sheath 6 will also change accordingly. At this time, the length of the hanging end of the sheath 6 will also change. Since the length of the entire traction rope 5 is fixed, when the length of the sheath 6 end changes, when the handle 7 end pulls the sheath 6 to the same height, the rising height of the handle 7 end is different, and the stretching distance of the patient's hand is limited. In order to adapt to the stretching of the patient's hand, the handle 7 is provided with multiple.

[0031] Specifically, Figure 1 As shown, a plurality of handles 7 are evenly spaced on the two supporting ropes 52, and the handles 7 at multiple positions can allow the patient to select a suitable holding position within a limited stretching distance.

[0032] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
