Description

Technical Field

[0001] This utility model relates to the field of medical device technology; more specifically, it relates to an auxiliary traction device for trauma orthopedics. Background Technology

[0002] Traction techniques utilize continuous traction force to reduce and fix fractures or dislocations, immobilize inflamed limbs, correct limb contractures and deformities, and provide functional exercises, all of which have certain therapeutic effects. Therefore, the design of auxiliary traction devices for trauma orthopedics is particularly important.

[0003] Currently, some existing traction devices are not convenient for bending and tractioning the patient's legs, resulting in a lack of bending exercises, which leads to slow treatment or the need for assistance from medical staff, increasing their workload. Furthermore, existing traction devices are not easy to adjust according to the size of the patient's ankle, resulting in unsuitable ankle fixation, reduced patient comfort, and an increased risk of ankle injury. Therefore, there is an urgent need for a trauma orthopedic auxiliary traction device to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a trauma orthopedic auxiliary traction device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a trauma orthopedic auxiliary traction device, comprising:

[0006] The hospital bed has a support fixed on one side, and turntables are inserted into both ends of one side of the support at an angle. A conveyor belt is fitted between the two sets of turntables. A support frame is inserted through the middle of the top surface of the hospital bed, and a round wheel is inserted into the bottom of the support frame. A cam is fixed to one side of one set of turntables through a bearing seat.

[0007] The top surface of the hospital bed is slidably fitted with two sets of first support frames arranged in a mirror image. A sliding rod is fixed to one side of each first support frame, and a second support frame is slidably fitted onto the outer surface of the sliding rod. The lower end of the second support frame is fixed to the hospital bed. A first spring is fixed between the first and second support frames and is fitted onto the sliding rod. An ankle clamp is rotatably inserted between the two sets of first support frames. Two sets of ankle clamps are provided, with one set located directly above the other set. A limit rod is fixed to one side of one set of ankle clamps, and a slot is provided on one side of the limit rod. A limiting block is slidably inserted into one side of the other set of ankle clamps, and a limiting block is slidably inserted into one side of the other set of ankle clamps. A second spring is fixed between the limiting block and the inner wall of the other set of ankle clamps.

[0008] Preferably, one side of the cam is configured as a triangular block, and one side of the triangular block is configured as an arc. The triangular blocks are evenly distributed on one side of the cam in a circumferential array. The lower surface of the wheel is movably engaged with the cam, so that the rotation of the cam can drive the wheel to slide up and down.

[0009] Preferably, the card slots are provided in multiple sets, and the multiple sets of card slots are equally distributed on one side of the limiting rod in a linear array. One end of the limiting block is slidably inserted into the card slot, so that the limiting rod can be adjusted to different heights as needed.

[0010] Preferably, there are two sets of limiting rods. One end of one set of limiting rods is fixed to one side of one set of ankle clips, and the other end of one set of limiting rods is inserted through and into one side of another set of ankle clips. One side of the other set of limiting rods does not have a slot. One end of the other set of limiting rods is fixed to one side of one set of ankle clips, and the other end of the other set of limiting rods is inserted through and into one side of another set of ankle clips, so that one set of ankle clips can slide stably.

[0011] Preferably, one end of the limiting block is configured as a large rectangular block, and the other end of the limiting block is configured as a rectangular strip. The length of the rectangular strip is equal to the length of the limiting block, and one end of the limiting block is flush with the rectangular strip, so that one end of the limiting block can restrict the rectangular strip at one end of the limiting block, thereby limiting the position of the limiting block.

[0012] Preferably, the outer surfaces of the support frame and the ankle clamp are covered with soft sponge padding to increase patient comfort and reduce the risk of injury to the patient from the device.

[0013] The technical effects and advantages of this utility model are as follows: This utility model uses a combination of a hospital bed, a support frame, a turntable, a conveyor belt, a lifting frame, a wheel, and a cam to allow the device to bend the patient's legs, thereby achieving the effect of bending and exercising the patient's legs. When the patient's legs are bent during traction, it can also promote blood circulation, increase the patient's treatment effect, and the patient can operate it by himself, reducing the workload of medical staff. At the same time, the patient can also control the degree of traction according to the specific situation, thereby improving the patient's comfort.

[0014] The device works in conjunction with the first support frame, ankle clamp, limiting rod, slot, limiting block, and second spring to adjust to the size of the patient's ankle, thereby reducing the damage to the patient's ankle. The appropriate size also improves the patient's comfort. The operation is simple and applicable to most patients, making it highly adaptable and reducing the probability of needing to replace the device due to an unsuitable size.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The instrument placement rack involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] like Figures 1 to 3 As shown, this embodiment proposes a trauma orthopedic auxiliary traction device, including a hospital bed 1. A support 2 is fixed on one side of the hospital bed 1, and turntables 3 are rotatably inserted at both ends of one side of the support 2 at an oblique position. A conveyor belt 4 is sleeved between the two sets of turntables 3. A lifting frame 5 is inserted through the middle of the top surface of the hospital bed 1, and a wheel 6 is rotatably inserted at the bottom end of the lifting frame 5. A cam 7 is fixed on one side of one set of turntables 3 through a bearing seat. One side of the cam 7 is set as a triangular block, and one side of the triangular block is set as an arc. The triangular blocks are evenly distributed on one side of the cam 7 in a circumferential array. The bottom surface of the wheel 6 is movably engaged with the cam 7.

[0024] In this embodiment, the patient is first laid flat on the top surface of the bed 1. The patient's ankles are then secured, and the patient's knees are placed on the outer surface of the support frame 5. One set of turntables 3 is then rotated, causing the conveyor belt 4 to rotate. The conveyor belt 4 then rotates the other set of turntables 3, which in turn rotates the cam 7. Because one side of the cam 7 is uneven, it causes the wheel 6 to rotate while simultaneously sliding up and down. The wheel 6 then causes the support frame 5 to slide up and down, which in turn causes the patient's legs to slide up and down. When the patient's legs slide upwards, the patient's ankle retracts, pulling the ankle clamp 12 to slide. The ankle clamp 12 then... The first support frame 8 slides, pulling one end of the first spring 11. Under the influence of the rebound force of the first spring 11, the ankle clamp 12 is also subjected to the rebound force of the first spring 11. The ankle clamp 12 then pulls the patient's ankle under the rebound force of the first spring 11, thereby achieving the purpose of traction on the patient's leg. At the same time, due to the bending of the patient's leg, the angle of the ankle changes, causing the ankle clamp 12 to rotate between the two sets of first support frames 8. As the cam 7 rotates, the wheel 6 slides up and down, and the wheel 6 drives the lifting frame 5 to slide up and down. The lifting frame 5 causes the patient's leg to bend up and down, thereby achieving the purpose of bending exercise for the patient's leg.

[0025] Example 2

[0026] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, based on the same concept as the above embodiment, this embodiment also proposes: two sets of first support frames 8 are slidably inserted into the top surface of the hospital bed 1 in a mirror-image arrangement, and a sliding rod 9 is fixed to one side of the first support frame 8. A second support frame 10 is slidably sleeved on the outer surface of the sliding rod 9, and the lower end of the second support frame 10 is fixed to the hospital bed 1. A first spring 11 is fixed between the first support frame 8 and the second support frame 10, and the first spring 11 is sleeved on the sliding rod 9. An ankle clip 12 is rotatably inserted between the two sets of first support frames 8, and two sets of ankle clips 12 are provided. One set of ankle clips 12 is located directly above the other set of ankle clips 12. A limiting rod 13 is fixed to one side of one set of ankle clips 12, and a slot 14 is opened on one side of the limiting rod 13. A limiting block 15 is slidably inserted into one side of the other set of ankle clips 12, and a limiting block 16 is slidably inserted into one side of the other set of ankle clips 12. The limiting block 15 and the other set of ankle clips 12... A second spring 17 is fixed between the inner walls. Multiple sets of slots 14 are provided. The multiple sets of slots 14 are distributed equidistantly on one side of the limiting rod 13 in a linear array. One end of the limiting block 16 is slidably inserted into the slot 14. Two sets of limiting rods 13 are provided. One end of one set of limiting rods 13 is fixed to one side of one set of ankle clips 12. The other end of one set of limiting rods 13 is inserted through and into one side of another set of ankle clips 12. One side of the other set of limiting rods 13 does not have a slot 14. One end of the other set of limiting rods 13 is fixed to one side of one set of ankle clips 12. The other end of the other set of limiting rods 13 is inserted through and into one side of another set of ankle clips 12. One end of the limiting block 16 is set as a large rectangular block. The other end of the limiting block 16 is set as a rectangular strip. The length of the rectangular strip is equal to the length of the limiting block 15. One end of the limiting block 15 is flush with the rectangular strip. The outer surfaces of the support frame 5 and the ankle clip 12 are covered with sponge pads.

[0027] In this embodiment, to fix the patient's ankle, first pull the limiting block 15 upwards. At this time, the second spring 17 is compressed. Then, pull the rectangular strip at one end of the limiting block 16. The rectangular strip drives the rectangular block away from the inside of the slot 14 until one side of the rectangular strip is directly below one end of the limiting block 15. Then release the limiting block 15. At this time, the limiting block 15 is affected by the rebound force of the second spring 17, so that one side of the limiting block 15 is tightly attached to one side of the rectangular strip. At this time, the limiting rod 13 is not restricted. Then, pull one set of ankle clips 12. One set of ankle clips 12 drives the limiting rod 13 to slide, so that the gap between the two sets of ankle clips 12 increases until it is suitable. After determining the size, the patient's ankle is placed between two sets of ankle clips 12. Then, one set of ankle clips 12 is moved to reduce the size between the two sets of ankle clips 12 until a suitable position is reached. Then, the limiting block 15 is pulled, at which point the second spring 17 is compressed until one side of the limiting block 15 moves away from one side of the rectangular strip. Then, the rectangular strip is pulled, and the rectangular strip drives the rectangular block to slide until the rectangular block slides into the corresponding set of slots 14. Then, the limiting block 15 is released. At this time, the limiting block 15 slides downward under the influence of the rebound force of the second spring 17, thereby achieving the purpose of limiting the rectangular strip of the limiting block 16, thus achieving the purpose of adjusting the size of the patient's ankle.
