[0023] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] like Figure 1-8 As shown, a bone traction device for fracture rehabilitation includes a support frame 1, wherein the two ends of the support frame 1 are hinged with a bracket 2 and a traction frame 3, and the bracket 2 and traction frame 3 are both connected with an adjustment member for adjusting the hinge angle. The support frame 1 is provided with a vertical frame 4 at one end close to the traction frame 3, and the traction frame 3 and the vertical frame 4 are both connected with a pulley 5, and the pulley 5 is provided with a traction member for tractioning the injured part of the patient. The top of the support frame 1 is provided with a first slide rail 6, and the top of the bracket 2 is provided with a second slide rail 7. The first slide rail 6 and the second slide rail 7 are both overlapped with a number of first support plates 8, and the first support plate 8 is covered with an anti-pressure pad 9, and the two ends of the first support plate 8 are fixed with overlapping grooves 10 for overlapping the first slide rail 6 or the second slide rail 7, and the overlapping grooves 10 are provided with overlapping locking members 11 for locking the overlapping position of the first support plate 8.

[0025] Working principle: the pulley 5 can be installed on the top of the traction frame 3 or the stand 4 through the pulley frame; the traction member includes a traction rope connected to the pulley 5, and the traction rope is connected to a traction bow at one end close to the bracket 2, and a weight is connected to the other end. The traction bow can also be a steel needle or traction clamp, which should be sterilized before use. The suspended weight of the weight is used as the traction force. The weight of the weight needs to be adjusted in time by medical staff according to the patient's reaction and treatment effect. The weight is preferably a weight with a calibrated weight; Usage steps: first, overlap several first support plates 8 on the first slide rail 6 and the second slide rail 7, and lock the overlapping position of the first support plates 8 by the locking member 11. The spacing between adjacent first support plates 8 can be shortened by increasing the number of first support plates 8, thereby increasing the support surface and improving the support Effect, then lay an anti-pressure pad 9 on the first support plate 8, the patient puts the part that needs treatment on the anti-pressure pad 9, and adjusts the bracket 2 and the traction frame 3 to a suitable hinge angle through the adjustment part (the bracket 2 can support the uninjured part of the patient), and then installs and fixes the traction part: the medical staff selects a hanging weight of appropriate weight, a traction rope of appropriate length and a device suitable for connection with the injured part of the patient according to the injured part and the degree of injury of the patient, and installs it. The overlapping first support plate 8 is used instead of the bandage for support. Since the first support plate 8 can be slidably installed to the appropriate installation position, the appropriate number of first support plates 8 can be selected as needed, which reduces the utilization rate of consumables and can be recycled. The use of anti-pressure pads instead of towels is more convenient and easy to clean than using several towels.

[0026] Preferably, the anti-pressure pad 9 is a multi-layer structure, which consists of a memory foam layer 91 and a breathable fiber leather layer 92 from the inside to the outside. The memory foam layer 91 has the property of reducing pressure, which can improve comfort and help the patient to recover from traction of the injured part. In addition to being breathable, the breathable fiber leather layer 92 is also wear-resistant and waterproof. Compared with genuine leather, it is more environmentally friendly and cost-effective, and can be recycled after disinfection or cleaning, which can greatly save the cost of using the device.

[0027] Preferably, the overlapping locking member 11 includes a clamping plate 111 and a bolt 112, and the clamping plate 111 is slidably connected to the inner bottom of the overlapping groove 10, and a threaded hole that matches the thread of the bolt 112 is opened on the side of the overlapping groove 10 away from the first support plate 8, and the bolt 112 passes through the threaded hole and is fixedly connected to the clamping plate 111. After the first support plate 8 is overlapped on the first slide rail 6 or the second slide rail 7 through the overlapping groove 10, the bolt 112 is rotated to clamp the first slide rail 6 or the second slide rail 7 through the clamping plates 111 at both ends of the first support plate 8. The overlapping locking member 11 can, but is not limited to, lock the overlapping position of the first support plate 8 in the above manner, and will not be affected by the different track spacings between the first slide rail 6 and the second slide rail 7. The side of the clamping plate 111 close to the slide rail can be provided with a rubber layer to increase friction to enhance the clamping effect.

[0028] Preferably, the first support plate 8 on the support frame 1 or the bracket 2 is provided with a plurality of first plug holes 12 on adjacent sides, and the second support plate 13 is plugged into the first plug holes 12. By plugging the second support plate 13, the support area can be increased while maintaining the same first support plate 8; while maintaining the same support effect, the number of first support plates 8 installed is reduced, and the installation time is shortened.

[0029] Preferably, second plug-in holes 14 are provided on both sides of the second support plate 13, and an extension plate 15 is inserted into the second plug-in hole 14. The extension plate 15 is provided with a plug-in locking member 16 for locking the plug-in position, and the plug-in locking member 16 includes a bolt. A plurality of internal threaded locking holes are provided at the bottom of the second support plate 13, and the threaded locking holes match the bolt threads. The provision of the extension plate 15 can reduce the number of first support plates 8 to be installed and shorten the installation time.

[0030] Preferably, the upper surface of the first support plate 8 is provided with a concave arc-shaped groove 17, so that the first support plate 8 can fit the patient better when in use, further improving the patient's comfort.

[0031] Preferably, the traction frame 3 and the vertical frame 4 are both connected to the support frame 1 through a telescopic support rod 18 connected at the bottom. The telescopic support rod 18 is provided with a limiter for limiting its telescopic length. The limiter can be a pin. By adjusting the telescopic support rod 18, the height of the pulley on the vertical frame 4 is higher than the pulley on the traction frame 3. The traction rope pulls the injured part of the patient upward, which can reduce the force on the first support plate 8 and improve the comfort of the patient when using it.

[0032] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
