Technical Field

[0001] This invention relates to the field of limb traction technology, and more specifically, to a limb traction and stretching device for use in traditional Chinese medicine orthopedics. Background Technology

[0002] Orthopedic limb traction is a basic orthopedic technique that uses continuous and appropriate traction force to act on bones or limbs to achieve specific therapeutic goals. Its core principle is to counteract muscle spasmodic contraction through the interaction of traction force and counter-traction force, so that fractures or dislocations can be reduced and fixed. Traction can be divided into skin traction, bone traction and cloth traction according to the location where the traction force is applied.

[0003] However, existing limb traction and stretching devices used in traditional Chinese medicine orthopedics lack versatility when applying traction to patients' limbs. Different devices need to be used when applying traction to the upper and lower limbs, which affects efficiency, increases treatment costs, and ultimately reduces the traction effect of the traction and stretching devices. Summary of the Invention

[0007] Preferably, the friction ring is covered with an elastic ring, the elastic ring is hollow, and a pair of fixing grooves are provided on the outer side of the elastic ring. The two ends of the control belt passing through the elastic ring are respectively passed through the two fixing grooves, and the two ends of the control belt are connected to a pull plate.

[0008] Preferably, both ends of the control belt are provided with baffles, and both ends of the baffles are provided with connecting handles, with one side of the baffles contacting the outer side of the elastic ring.

[0009] Preferably, the load assembly includes a traction rope connected to one end of the end plate, a bearing plate connected to the free end of the traction rope, a bracket provided at the end of the traction plate away from the connecting assembly, a guide wheel hinged to the top of the bracket, and the traction rope being secured to the outside of the guide wheel.

[0010] Preferably, the bottom end of the support is provided with a distance fixing component, the distance fixing component includes a base plate provided at the bottom end of the support, a card holder is slidably mounted on the support, a pair of clamping blocks are slidably mounted on the card holder, and the two clamping blocks are respectively located on both sides of the traction rope.

[0011] Preferably, a magnetic block is provided on the outside of the card holder, the base plate and the magnetic block are arranged in the same vertical direction, an electromagnet is provided on the base plate, an electromagnetic plate is provided on the clamping block, and the two electromagnetic plates are arranged opposite to each other.

[0012] Preferably, the traction plate has a slot, in which a slide rod is slidably engaged. Both ends of the slide rod are connected to a movable frame, which is slidably engaged on the traction plate. A side plate is provided on one side of the traction plate, and a telescopic rod is provided on one side of the side plate. The output end of the telescopic rod is connected to the movable frame.

[0013] Preferably, the movable frame has side slots on both sides, and a slider is slidably engaged in the side slot. The two sliders are connected by a fixed rod, and a winding device is rotatably engaged on the fixed rod. The output end of the winding device is connected to a traction frame by a pull rope.

[0014] Preferably, the connecting assembly includes a first connecting plate rotatably connected to the outside of the tray, the first connecting plate being connected to a pair of second connecting plates via a telescopic pad, and the two second connecting plates being connected by a breathable pad.

[0015] Preferably, a pair of connecting shafts are provided at one end of the traction plate near the second connecting plate, and the two connecting shafts are respectively inserted through one end of the two second connecting plates. The traction plate is provided with a groove, and there is a gap between the traction plate and the breathable pad.

[0016] The principle and beneficial effects of this technical solution:

[0017] (1) The support plate provided in this invention can be used with the connecting component and the traction component to traction the patient's limb. By setting multiple traction methods, the traction method can be adjusted accordingly for different limbs or different limb conditions of the patient. When using this device to traction the upper limb, place the patient's forearm on the traction plate, and put the two friction rings on the traction plate connected by the end plate and the fixed plate on the outside of the patient's forearm respectively. After the traction plate is tightly connected to the patient's forearm, adjust the length of the telescopic pad in the connecting component so that the first connecting plate and the second connecting plate connected at both ends of the telescopic pad are equal in length to the patient's hind arm. After completing the above operation, place the counterweight block corresponding to the required traction weight on the bearing plate at the bottom of the traction rope. The traction rope will pull the traction plate under the gravity of the counterweight block. While the traction plate moves, it will simultaneously pull the patient's forearm to traction the patient's forearm.

[0018] (2) The traction frame provided in this invention enables the device to perform bone traction on the patient's lower limb. When the patient's lower limb needs to be tractioned, the support plate is raised by the connecting component, the patient's lower limb to be traction is placed on the support plate, and then the telescopic rod is driven to reset. During the resetting process of the telescopic rod, the sliding rod connected to the moving frame will be pulled to move along the slot opened on the traction plate, so that the moving frame connected to the output end of the telescopic rod moves to the position closest to the connecting component. Then, the slider on the moving frame that is slidably locked by the side slot can be slid to the appropriate position.

[0019] (3) The distance setting component in this invention can limit and measure the distance of the traction rope moving down. When using the distance setting component, the electromagnetic plate set on the clamp block is energized. When the electromagnetic plate is energized, the two clamp blocks on which it is located will move closer to each other. When the two clamp blocks move closer, they will clamp the traction rope. When the traction rope moves down, it will drive the two clamp blocks to move down synchronously. When the clamp blocks move down, the card frame on which they are located will move down together. By measuring the distance of the card frame sliding along the bracket, the distance of the traction rope moving down can be measured synchronously. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0027] Example:

[0028] like Figures 1 to 5 As shown, the present invention provides a limb traction and stretching device for traditional Chinese medicine orthopedics, including a support plate 1. A traction plate 3 is connected to the outside of the support plate 1 through a connecting component. A traction component is provided on the traction plate 3. The traction component includes an end plate 5 that is slidably locked on the traction plate 3. A load component is provided at one end of the end plate 5 away from the support plate 1. Multiple fixing plates 4 are evenly arranged at the other end of the end plate 5. Each fixing plate 4 is connected to a friction ring 25 through two sets of fixation plates 26. The friction ring 25 is made of elastic and breathable material.

[0029] like Figure 4 As shown, the friction ring 25 is covered by an elastic ring 23. The elastic ring 23 is hollow and has a pair of fixing grooves 24 on its outer side. The control belt 27, which is inserted into the elastic ring 23, has its two ends inserted into the two fixing grooves 24 respectively. The two ends of the control belt 27 are connected to a pull plate 30.

[0030] like Figure 4 As shown, baffles 28 are provided at both ends of the control belt 27, and connecting handles 29 are provided at both ends of the baffles 28. One side of the baffles 28 contacts the outer side of the elastic ring 23.

[0031] like Figures 1 to 3 As shown, the load assembly includes a traction rope 14 connected to one end of the end plate 5, a bearing plate 15 connected to the free end of the traction rope 14, a bracket 17 provided at the end of the traction plate 3 away from the connecting assembly, a guide wheel 16 hinged to the top of the bracket 17, and the traction rope 14 being secured to the outside of the guide wheel 16.

[0032] like Figure 3As shown, a distance fixing component is provided at the bottom of the bracket 17. The distance fixing component includes a base plate 22 provided at the bottom of the bracket 17. A card holder 18 is slidably attached to the bracket 17. A pair of clamping blocks 20 are slidably attached to the card holder 18. The two clamping blocks 20 are respectively located on both sides of the traction rope 14.

[0033] like Figure 3 As shown, a magnetic block 19 is provided on the outside of the card holder 18, the base plate 22 and the magnetic block 19 are arranged in the same vertical direction, an electromagnet is provided on the base plate 22, and an electromagnetic plate 21 is provided on the clamping block 20, with the two electromagnetic plates 21 arranged opposite to each other.

[0034] like Figures 1 to 3 as well as Figure 5 As shown, a slot 6 is provided on the traction plate 3, and a slide rod 11 is slidably locked in the slot 6. Both ends of the slide rod 11 are connected to a movable frame 10. The movable frame 10 is slidably locked on the traction plate 3. A side plate 33 is provided on one side of the traction plate 3, and a telescopic rod 34 is provided on one side of the side plate 33. The output end of the telescopic rod 34 is connected to the movable frame 10.

[0035] like Figure 3 As shown, the movable frame 10 has side slots 9 on both sides, and a slider 13 is slidably mounted in the side slot 9. The two sliders 13 are connected by a fixed rod 12. A winder 7 is rotatably mounted on the fixed rod 12, and the output end of the winder 7 is connected to a traction frame 8 by a pull rope.

[0036] The distance-fixing component can limit and measure the downward movement distance of the traction rope 14. When using the distance-fixing component, the electromagnetic plate 21 set on the clamp 20 is energized. When the electromagnetic plate 21 is energized, it will cause the two clamps 20 to move closer to each other. When the two clamps 20 move closer, they will clamp the traction rope 14. When the traction rope 14 moves downward, it will synchronously drive the two clamps 20 to move downward. When the clamps 20 move downward, the card holder 18 on which they are located will move downward together. By measuring the distance that the card holder 18 slides along the bracket 17, the downward movement distance of the traction rope 14 can be synchronously measured. Before the device is used for distance measurement next time, the electromagnet set on the base plate 22 can be energized to make the electromagnet repel the magnetic block 19 set on the outside of the card holder 18 so as to drive the card holder 18 to reset.

[0037] like Figure 1 and Figure 5 As shown, the connecting assembly includes a first connecting plate 2 rotatably connected to the outside of the tray 1. The first connecting plate 2 is connected to a pair of second connecting plates 37 via a telescopic pad 35. The two second connecting plates 37 are connected by a breathable pad 36.

[0038] like Figure 1 and Figure 5As shown, a pair of connecting shafts 31 are provided at one end of the traction plate 3 near the second connecting plate 37. The two connecting shafts 31 are respectively inserted through one end of the two second connecting plates 37. The traction plate 3 is provided with a groove 32, and there is a gap between the traction plate 3 and the air cushion 36.

[0039] The traction frame 8 allows the device to perform bone traction on the patient's lower limb. When traction is needed, the support plate 1 is raised by the connecting component, and the patient's lower limb to be traction is placed on the support plate 1. Then, the telescopic rod 34 is driven to reset. During the reset process, the telescopic rod 34 pulls the slide rod 11 connected to the movable frame 10 to move along the slot 6 opened on the traction plate 3. After the movable frame 10 connected to the output end of the telescopic rod 34 is moved to the position closest to the connecting component, the slider 13 on the movable frame 10, which is slidably locked by the side slot 9, is slid to the appropriate position. The fixed rod 12 connected between the two sliders 13 moves synchronously. After the fixed rod 12 is adjusted to the appropriate height, the retractor 7 is driven to pull the traction frame 8 connected to the pull rope to the position of the patient's lower limb fixation bone fixation nail.

[0040] The specific usage and function of this embodiment are as follows:

[0041] The support plate 1 in this invention can be used with the connecting component and the traction component to traction the patient's limb. By setting multiple traction modes, the traction mode can be adjusted accordingly for different limbs or different limb conditions. When using this device for upper limb traction, the patient's forearm is placed on the traction plate 3, and the two friction rings 25 connected to the traction plate 3 by the end plate 5 and the fixing plate 4 are respectively sleeved on the outside of the patient's forearm. Then, the pull plate 30 set on the outside of the two friction rings 25 is pulled. During the outward movement of the pull plate 30, the control band 27 connected to one side is pulled simultaneously. During the pulling of the control band 27, the two ends of the control band 27 slide along the baffle 28, and the friction band contracts. The elastic ring 23 covering the outer side of the ring 25 will cause the friction ring 25 inside it to contract during the contraction process, so that the friction ring 25 is in close contact with the patient's forearm. After the traction plate 3 is tightly connected to the patient's forearm, the length of the telescopic pad 35 in the connecting assembly is adjusted so that the length of the first connecting plate 2 and the second connecting plate connected to both ends of the telescopic pad 35 is equal to that of the patient's hind arm. After the above operation is completed, a counterweight corresponding to the required traction weight is placed on the bearing plate 15 at the bottom of the traction rope 14. The traction rope 14 will pull the traction plate 3 under the gravity of the counterweight. While the traction plate 3 moves, it will simultaneously pull the patient's forearm to traction the patient's forearm.
