Description

Technical Field

[0001] The invention relates to the technical field of medical care, and in particular to an orthopedic care traction bracket which is easy to adjust. Background Art

[0002] Fracture traction is a commonly used treatment technique in orthopedics. It uses the principle of mechanical action and reaction to relieve the tension and retraction of soft tissue, reduce fractures or dislocations, and prevent and correct deformities.

[0003] The existing orthopedic nursing traction usually uses a traction bed, which is used by medical staff or family members to implement traction exercises on the patient's lower limbs. Since the traction operation mostly relies on the experience and judgment of medical staff or family members, and lacks accurate quantitative standards, it may cause the traction force to be too large or too small. In addition to causing pain, excessive force may also cause reinjury to the fracture site or soft tissue damage; too little force may not achieve effective treatment effects, prolong the recovery period, and inappropriate traction methods may also increase the risk of complications, such as compression of nerves and blood vessels, joint stiffness, muscle atrophy, etc. These complications not only affect the patient's recovery process, but also may bring additional pain and burden to the patient. At the same time, during the traditional traction process, the patient is often in a passive position of receiving treatment and lacks the opportunity to actively participate and control. This is not conducive to stimulating the patient's rehabilitation motivation and also limits the further improvement of the rehabilitation effect. Therefore, the present invention provides an orthopedic nursing traction bracket that is easy to adjust to meet the needs. Summary of the invention

[0015] Compared with the prior art, the present invention has at least the following beneficial effects:

[0016] In the above scheme, by setting the adjustment component, the multi-directional adjustment of the patient's legs can be easily achieved through the bracket during use. Because it is driven by the machine, the operator can stably control the applied force, effectively preventing the problem of too large or too small force, thereby improving the effectiveness and safety of traction care, and it is worthy of promotion and use;

[0017] In the above scheme, by setting a No. 1 limiter and a gradient limiter cavity according to the No. 1 limiter, this design can adapt to thighs of different thicknesses, ensuring that no matter what the patient's body shape is, a suitable fixed position can be found to achieve effective traction fixation. When the limiter sleeve contacts and tightens the thigh, it can fit the contour of the thigh more closely, reduce gaps and shaking, and thus enhance stability during traction. This is crucial to ensure the traction effect and avoid additional damage caused by unstable fixation. Compared with traditional fixation methods, the gradient limiter cavity design can better disperse pressure and reduce local pressure on the thigh. For patients who need to receive traction treatment for a long time, this can significantly improve comfort and reduce discomfort and pain caused by long-term fixation;

[0018] In the above scheme, by achieving more stable fixation and wider adaptability, the gradual limit cavity design helps reduce the risk of complications caused by improper fixation, such as nerve and blood vessel compression, skin damage, etc. This is of great significance for improving treatment effects and shortening the recovery period. Medical staff or family members do not need to frequently change fixation devices of different sizes to adapt to the thickness of different patients' thighs during operation. The gradual limit cavity design allows one set of devices to meet multiple needs, simplifies the operation process, and improves work efficiency.

[0019] In the above scheme, by setting up the guide part, during the process of limiting the thigh, the limiting sleeve can fit the contour of the thigh more closely and reduce gaps and shaking through the guidance of the guide part, thereby improving the stability and effect of fixation. The evenly expanded limiting sleeve can reduce the local pressure on the thigh, making the patient more comfortable when receiving traction treatment. Since the limiting sleeve can fit the thigh more evenly, the risks of skin damage, nerve and blood vessel compression caused by unstable fixation or excessive local pressure are reduced. During the operation, medical staff or family members do not need to adjust the position or angle of the limiting sleeve too much, and can achieve a good fixation effect by applying appropriate pressure along the direction of the guide part, thereby simplifying the operation process.

The top of the No. 3 limit frame 801 is provided with a rolling groove for the rolling of the roller 806. The base 1 is firmly placed on the ground, and the support frame 2 and the seat 3 are fixedly connected to the base 1 to form a basic supporting structure. The driving motor is started, and the driving motor drives the transmission screw 402 to rotate. Due to the effect of the threaded connection, the lifting member 5 moves horizontally along the No. 1 limit frame 401.The initial position of the entire bracket is adjusted to fit the patient's legs, the bolts on the lifting sleeve 502 are rotated and unscrewed, the lifting connecting rod 503 is pulled up, so that the lifting connecting rod 503 moves upward, and then the height is adjusted and fixed by cooperating with the adjustment hole, and the rotating disk 603 is rotated to drive the double-thread screw 602 to rotate in the second limit frame 601. Due to the symmetrical thread design of the double-thread screw 602, the two No. 2 transmission members 701 will move in opposite directions at the same time, thereby adjusting the horizontal position of the No. 1 limit member 7, fixing the patient's thigh on the No. 1 limit member 7, and forcibly pushing the No. 3 transmission block 803, so that the No. 3 transmission block 803 moves forward to the patient's ankle to fix the patient's foot.

Through threaded connection, sliding connection and roller 806 rolling, the smoothness during the adjustment process and the stability after fixation are ensured. Patients or medical staff can make fine adjustments as needed during the treatment process, which increases the patient's active participation and helps to improve rehabilitation motivation. ,

[0033] In this embodiment, if Figures 2 to 6As shown, a limiting cavity 705 with a gradually changing aperture is provided inside the limiting sleeve 702, an arc-shaped guide portion 704 is provided on the top of the limiting sleeve 702, and the second limiting member 9 includes a connecting column 901 fixedly connected to the top of the third transmission block 803, and a supporting sleeve 902 is fixedly connected to the top of the connecting column 901. The support sleeve 902 is in a flat "U" shape, and strap holes 903 are provided on both sides of the support sleeve 902. The limiting cavity 705 with a gradually changing aperture opened inside the limiting sleeve 702 is unique in design, and its aperture gradually changes from large to small. This design enables the limiting sleeve 702 to gradually adapt to and closely fit thighs of different thicknesses when subjected to external forces (such as pressure from the patient's thigh). When the limiting sleeve 702 is put on the thigh, the wider aperture portion first contacts the thigh. As it is further inserted, the gradually narrowing aperture portion will gradually compress and fit the thigh, achieving a stable fixing effect. The arc-shaped guide portion 704 at the top of the limiting sleeve 702 plays a role in guiding and assisting insertion. The arc-shaped design makes the limiting sleeve 702 smoother when inserted into the thigh, reducing friction and discomfort with the skin. The guide portion 704 can also disperse the pressure generated during insertion to a certain extent, making the entire insertion process smoother and more comfortable. The second limiting member 9 includes a connecting column 901 fixedly connected to the top of the third transmission block 803, and a supporting sleeve 902 fixedly connected to the top of the connecting column 901. The support sleeve 902 is in a flat "U" shape, with strap holes 903 on both sides. When the limiting sleeve 702 fits tightly on the thigh, the flat "U" shape of the support sleeve 902 can stably support the ankle, and the strap passing through the strap hole 903 can further fix the support sleeve 902 and the ankle together, increasing the stability and reliability of the fixation. The limiting cavity 705 with a gradually changing aperture can fit tightly to thighs of different thicknesses, ensuring the stability of the traction device during the traction process. The flat "U" shape of the support sleeve 902 and the strap fixing method of the strap hole 903 further The stability and reliability of fixation are enhanced. The design of the arc-shaped guide part 704 reduces friction and discomfort during insertion, making the patient more comfortable during use. The soft and adaptable limiting sleeve 702 material can also reduce pressure and discomfort on the skin. Since the designs of the limiting sleeve 702 and the support sleeve 902 take adaptability and adjustability into consideration, medical staff or patients can make fine adjustments based on actual conditions to meet different treatment needs. The stable fixation and comfortable design reduce the risk of complications such as neurovascular compression and skin damage caused by improper fixation.

[0034] In this embodiment, if Figure 7As shown, the front of the lifting connection rod 503 is fixedly connected with an adjusting member 10, and the adjusting member 10 includes an adjusting frame 1001 fixedly connected to the front of the top of the lifting connection rod 503, the inside of the adjusting frame 1001 is rotatably connected with an adjusting screw 1002, the external thread of the adjusting screw 1002 is connected with an adjusting movable block 1003, both sides of the adjusting movable block 1003 are rotatably connected with adjusting connecting rods 1004, the bottom of the other end of the two No. 3 transmission frames 8 are fixedly connected with a bottom plate 1005, the other ends of the two adjusting connecting rods 1004 are rotatably connected to one side of the bottom plate 1005, and the adjusting screw 1002 is rotated to make the adjusting movable block 1003 translate outside the adjusting screw 1002, so that the two adjusting connecting rods 1004 are opened in an eight-shaped shape, and one end of the No. 3 transmission frame 8 is stretched to both sides, so that the legs of the top patient after being fixed can be opened and closed.

[0035] The working principle provided by the present invention is that the base 1 is firmly placed on the ground, the support frame 2 and the seat 3 are fixedly connected to the base 1 to form a basic supporting structure, the driving motor is started, and the driving motor drives the transmission screw 402 to rotate. Due to the effect of the threaded connection, the lifting member 5 moves horizontally along the No. 1 limit frame 401, and the initial position of the entire bracket is adjusted so that it can adapt to the patient's legs. The bolts on the lifting sleeve 502 are rotated and unscrewed, and the lifting connecting rod 503 is pulled up to move the lifting connecting rod 503 upward, and then the height adjustment and fixation are achieved by cooperating with the bolts and the adjustment holes, and the rotating disk 603 is rotated to drive the double-thread screw 602 to rotate in the No. 2 limit frame 601. Due to the symmetrical thread design of the double-thread screw 602, the two No. 2 transmission members 701 will move in opposite directions at the same time, thereby adjusting the horizontal position of the No. 1 limit member 7, fixing the patient's thigh on the No. 1 limit member 7, and forcibly pushing the No. 3 transmission block 803, so that the No. 3 transmission block 803 moves forward to the patient's ankle to fix the patient's foot. The No. 3 transmission frame 8 allows further fine-tuning of the angle and direction of the traction device through the combination of the No. 3 limit frame 801, the No. 3 transmission block 803 and the docking button 805. The No. 3 transmission block 803 slides in the guide groove of the No. 3 limit frame 801 and is rolled. The wheel 806 rolls in the rolling groove to achieve smooth and stable movement. The adaptive design of the docking button 805 and the docking groove 804 ensures stability and accuracy during fine-tuning. At this time, the entire traction bracket has completed all-round adjustment and fixation according to the patient's specific situation and treatment needs. The adjusting screw 1002 is rotated to allow the adjusting movable block 1003 to translate outside the adjusting screw 1002, so that the two adjusting connecting rods 1004 are opened in an eight-shaped shape, and one end of the No. 3 transmission frame 8 is stretched to both sides, so that the legs of the patient at the top can be opened and closed after being fixed.
