Description
Technical Field
[0001] The invention relates to the technical field of rehabilitation equipment, in particular to a numerically controlled traction device for orthopedic rehabilitation. Background Art
[0002] Traction devices for orthopedic rehabilitation are an important type of equipment widely used in the field of orthopedic rehabilitation. They are mainly used for reduction and rehabilitation after fractures and joint dislocations, as well as the treatment and recovery of some spinal diseases. Orthopedic rehabilitation traction devices include cervical traction devices, lumbar traction devices and limb traction devices, and limb traction devices include upper limb traction devices and lower limb traction devices.
[0003] Among them, the upper limb traction device is mainly used for reduction and rehabilitation after upper limb fractures and dislocations, as well as the treatment of some upper limb joint diseases. It applies traction to various joints of the upper limbs (such as shoulder joints, elbow joints, and wrist joints) to correct joint deformities, restore the normal anatomical position of the joints, and promote fracture healing and joint function recovery. When in use, the upper limb traction device mainly uses straps to restrain and bind the patient's forearm. The original intention of this design was to use the forearm as a fulcrum to drive the elbow joint to move by traction on the forearm, thereby achieving rehabilitation training for the elbow joint.
[0004] During the rehabilitation training of the elbow joint, the direction of the palm is a key factor, which directly affects the movement pattern of the elbow joint and the angle of rehabilitation training. Different palm directions will cause the elbow joint to move in different planes and axes. The existing device must re-bind the straps, which not only requires patients or medical staff to spend more time and energy, but also the frequent adjustment of the straps may affect the patient's training experience and rehabilitation progress. Summary of the invention

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0032] The following describes an embodiment of the present invention based on its overall structure.
[0033] A numerically controlled orthopedic rehabilitation traction device, such as Figure 1-11 As shown, it comprises a main body 1, one end of the main body 1 is movably connected to a flip traction arm 2, and an adjusting ring 3 is slidably connected inside the flip traction arm 2;
[0034] The top and bottom of the adjusting ring 3 are both fixed with a slider 4 extending to the inside of the flip traction arm 2, and the top and bottom of the adjusting ring 3 are both movably connected with a movable adjusting plate 7, and the inner sides of the two sets of movable adjusting plates 7 are both provided with a binding piece 16, and the outer center positions of the two sets of movable adjusting plates 7 are both fixed with a movable universal ball 8 extending to the inside of the adjusting ring 3;
[0035] When the direction of the palm needs to be adjusted, the driving connecting rod 11 is driven to rotate along the adjusting ring 3 under the action of the driving gear ring 12. At this time, since the fixed universal ball 10 located inside the movable universal ball 8 is fixed at the middle position of the driving connecting rod 11, the two sets of movable adjustment plates 7 and the two sets of binding plates 16 can be adjusted as a whole, and then the direction of the palm can be adjusted by the forearm, so as to better perform rehabilitation training processes at different angles for the elbow joint, and at the same time, there is no need for medical staff to frequently adjust the straps, and the overall rehabilitation training effect is better and the operation is more convenient;
[0036] An annular ball groove 22 matching with two sets of movable universal balls 8 is provided inside the adjusting ring 3, and the driving gear ring 12 is rotatably connected at both ends of the adjusting ring 3. Matching limit rings 13 matching with the driving gear ring 12 are fixed at both ends of the adjusting ring 3, and an annular groove matching with the annular ball groove 22 is provided inside the matching limit ring 13. The two sets of matching limit rings 13 not only play a role in limiting the end surface of the driving gear ring 12, but also the annular grooves provided inside the matching limit rings 13 and the annular ball grooves 22 match and correspond to each other, which can play a role in limiting the movable universal balls 8 as a whole, and facilitate the movable universal balls 8 to move inside the matching limit rings 13 without causing the movable universal balls 8 to fall off.
[0037] A driving connecting rod 11 penetrating the movable universal ball 8 is fixed to the top and bottom between the two sets of driving gear rings 12, and a fixed universal ball 10 extending to the inside of the movable universal ball 8 is fixed at the middle position outside the driving connecting rod 11, and a matching cavity 9 matching with the fixed universal ball 10 is provided inside the movable universal ball 8, and through holes with a diameter larger than that of the driving connecting rod 11 are provided at both ends of the movable universal ball 8. When the movable universal ball 8 is fine-tuned relative to the adjustment ring 3, the movable universal ball 8 will not interfere with the driving connecting rod 11. At the same time, with the cooperation of the driving connecting rod 11 and the fixed universal ball 10, the movable universal ball 8 can be driven to perform circular adjustment of the angle of the palm facing inside the annular ball groove 22 in the adjustment ring 3;
[0038] A dual-axis motor 14 is installed at the middle position of one side inside the adjusting ring 3, and the output ends of both ends of the dual-axis motor 14 are fixed with driving gears 15 meshing with the two sets of driving gear rings 12.

[0039] The binding mechanism 5 also includes a reeling rod 502 and a tightening belt 504. Two groups of reeling rods 502 are rotatably connected inside the connecting plate 501, and tightening belts 504 are fixed on both sides of the reeling rods 502 and sequentially penetrate the two groups of movable adjustment plates 7 and the two groups of binding sheets 16.
[0040] The binding mechanism 5 further includes a transmission gear 503, a worm wheel 505, a worm 506 and a first hand wheel 507. The transmission gears 503 are respectively fixed to the outside of the two groups of winding rods 502 and mesh with each other, and the worm wheel 505 is fixed to the outside of one group of winding rods 502. A shell is provided on the outside of the binding mechanism 5, and a worm 506 meshing with the worm wheel 505 is rotatably connected inside the shell, and the first hand wheel 507 is fixed to the top of the worm 506.
[0041] An adjusting mechanism 6 is provided at one corner of the flip traction arm 2, and the adjusting mechanism 6 includes a screw rod 601, a first synchronous wheel 602, a second synchronous wheel 603, a synchronous belt 604 and a second hand wheel 605. The screw rod 601 passes through the two sets of sliders 4, and the two sets of first synchronous wheels 602 are respectively fixed on one side of the two sets of screw rods 601. A shell is provided on the outer side of the adjusting mechanism 6, and the second synchronous wheel 603 and the shell are rotatably connected. The second synchronous wheel 603 and the two sets of first synchronous wheels 602 are connected by a synchronous belt 604, and the second hand wheel 605 is fixed on one side of the second synchronous wheel 603.
[0042] The rotation of the second hand wheel 605 can drive the adjustment ring 3 to adjust the entirety under the cooperation of the screw rod 601 and the slider 4, so that the distance of the adjustment ring 3 relative to the bed can be adjusted, which is more convenient for the patient to use and has better applicability;
[0043] A binding mechanism 5 is arranged on the top of the flip traction arm 2, and the binding mechanism 5 includes a connecting plate 501, and the bottom of the connecting plate 501 is fixedly connected to one group of sliders 4. At the same time, since the binding mechanism 5 is fixed on the top of the slider 4, after the position of the adjusting ring 3 is adjusted, the binding mechanism 5 moves synchronously, which will not affect the problem of binding the patient's forearm after adjustment.
[0044] See also Figure 1 A clamping plate mechanism 19 is fixed on one side of the main body 1, a connector 20 connected to an external power supply device is fixed on one end of the main body 1, and a control board module 21 is fixed on the top of the main body 1. The present invention is provided with the above structure, wherein the connector 20 facilitates the power supply operation of the entire present invention, and the clamping plate mechanism 19 can clamp the entirety to one side of a bed or seat, which is more convenient to use.
[0045] The working principle of the present invention is as follows: when in use, the power is turned on, and the present invention is fixed as a whole on one side of a bed or a seat through the clamping plate mechanism 19, wherein the clamping plate mechanism 19 can adapt to the installation and use environment of the bed or the seat. Specifically, the clamping plate mechanism 19 uses a screw to drive the clamping plate to move, and clamps and fixes the external object, wherein the manual clamping or electric clamping method can be used. At the same time, a rubber strip is fixed on the inner side of the clamping plate, which improves the stability and firmness of the overall clamping;
[0046] Then the patient's forearm is placed between the two groups of binding plates 16, and then the first hand wheel 507 of the binding mechanism 5 is rotated, so that the two groups of tightening belts 504 drive the two groups of binding plates 16 to tighten and bind the patient's forearm;
[0047] Specifically, the two ends of the tightening belt 504 are respectively rolled up by a set of winding rods 502, wherein the two sets of winding rods 502 are meshed with each other through the transmission gear 503 to realize synchronous reverse rotation operation, thereby enabling the tightening belt 504 to drive the binding sheet 16 to tighten and bind the forearm;
[0048] At the same time, a worm wheel 505 is fixed on the outside of one of the winding rods 502, and the worm wheel 505 and the worm 506 are meshed with each other. The medical staff drives the worm 506 to rotate by turning the first hand wheel 507, and then drives the worm wheel 505 to rotate. The meshing between the worm wheel 505 and the worm 506 is more stable, and there is a self-locking function between them. After the tightening belt 504 is tightened, the tightening belt 504 will not loosen, so that the patient's forearm can be better bound and tightened;
[0049] Then, the forearm is driven to flip back and forth by flipping the traction arm 2, so that the elbow joint can be rehabilitated. When the direction of the palm needs to be adjusted, the driving connecting rod 11 is driven to rotate along the adjusting ring 3 under the action of the driving gear ring 12. At this time, since the fixed universal ball 10 located inside the movable universal ball 8 is fixed at the middle position of the driving connecting rod 11, the two sets of movable adjustment plates 7 and the two sets of binding plates 16 can be adjusted in overall angle, and the direction of the palm can be adjusted by the forearm, so as to better perform the rehabilitation training process of the elbow joint at different angles, and at the same time, there is no need for medical staff to frequently adjust the straps, and the overall rehabilitation training effect is good and the operation is convenient.
[0050] The main body 1 is provided with a flipping driving mechanism, wherein the flipping driving mechanism can drive the flipping traction arm 2 to perform a reciprocating flipping operation. Specifically, the flipping driving mechanism can be driven by a motor to realize the reciprocating flipping operation of the flipping traction arm 2;
[0051] Specifically, the two groups of movable adjustment plates 7 can be adjusted to an angle of 0-180 degrees relative to the adjustment ring 3 toward the patient's side, that is, the adjustment range of the palm orientation is from the palm facing up to the palm facing down. Different palm orientations can enable the elbow joint to move on different planes and axes, thereby achieving a variety of rehabilitation training angles to meet the needs of comprehensive recovery of the elbow joint function.
[0052] In other words, accurately controlling the different palm directions to adjust the training angle can more effectively stimulate the recovery of muscles, ligaments and joint tissues around the elbow joint. Training at different angles can promote the balanced development of muscle strength, increase the range of motion and flexibility of the joints, and improve the stability and coordination of the elbow joint.
[0053] Furthermore, after the forearm is fixed by two sets of binding plates 16, the two sets of movable adjustment plates 7 and the adjustment ring 3 are movably connected by the fixed universal ball 10, so that after the patient's forearm is fixed, the patient can actively make fine adjustments. At the same time, when used for patients in different positions such as lying or sitting, the placement state of the patient's forearm can be adaptively adjusted, effectively avoiding the discomfort caused by the difficulty of fine adjustment in the prior art during rehabilitation training, and the overall use effect is greatly improved;
[0054] Furthermore, since a matching cavity 9 matching with the movable universal ball 8 is provided inside the fixed universal ball 10, and through holes with a diameter larger than that of the driving connecting rod 11 are provided on both sides of the fixed universal ball 10, when the movable universal ball 8 is subjected to universal fine-tuning relative to the adjusting ring 3, the movable universal ball 8 will not interfere with the driving connecting rod 11. At the same time, with the cooperation of the driving connecting rod 11 and the fixed universal ball 10, the movable universal ball 8 can be driven to perform circular adjustment of the palm-facing angle inside the annular ball groove 22 in the adjusting ring 3.
