Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a traction recovery device for orthopedic nursing. Background Art

[0002] The tibia is the long bone on the medial side of the lower leg, divided into a body and two ends; the proximal end of the tibia is enlarged and protrudes to both sides to form the medial malleolus and the lateral condyle. The upper surfaces of the two condyles are smooth as articular surfaces, and the area between the two condyles is the intercondylar area, and its middle is the intercondylar eminence. There is a rough elevation in front of the proximal end of the tibia called the tibial tuberosity, which is the attachment point of the patellar ligament. There is a circular fibular articular surface behind the lateral condyle to articulate with the head of the fibula. In daily life, after the tibia is injured, medical rehabilitation of the tibia is required. During the rehabilitation process of the tibia, fracture traction treatment is needed to relieve limb swelling and pain and maintain the relative stability of the fracture.

[0003] The invention patent with the patent number CN111956314B discloses a traction recovery device for orthopedic nursing, which effectively solves the problem that the weights are prone to swing under the action of external forces during the traction process; it includes a fixed plate, on which a traction frame is slidably connected up and down. Two leg support sliding plates are slidably connected left and right at the bottom of the traction frame, and leg supports are slidably connected left and right on the leg support sliding plates. The spring stretching screw rod is slidably connected left and right on the traction frame, and the spring stretching screw rod is slidably connected with a spring stretching driven gear rotatably connected to the traction frame; achieving the effects of being easy to operate and having a stable structure.

[0004] The above device is slidably connected with a spring stretching driven gear rotatably connected to the traction frame through a spring stretching screw rod; achieving the effects of being easy to operate and having a stable structure, and during the recovery period of the patient, the traction force needs to be kept consistent to avoid bone displacement of the broken bone. After the recovery period, bone callus will grow on the broken bone surface of the patient. At this time, the traction force needs to be gradually reduced.

And because the recovery period varies with different fracture degrees, it is very easy for medical staff to be negligent and cause the traction force of the patient to be reduced untimely, resulting in the problem of nonunion of the patient's bones. The higher the corresponding fracture degree, the greater the traction force required at the fracture site, and sufficient space should be given to the fracture site for recovery.

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

First, fix the mounting plate 16 on the bed tail frame, then pass the puncture needle 1 through the tibia at the fracture site of the patient, then install the traction bow 2 on the puncture needle 1. Then, adjust the traction force magnitude of the traction mechanism 7 according to the fracture degree of the patient. The traction mechanism 7 pulls the second traction rope and the dynamometer 14. The dynamometer 14 successively pulls the first traction rope 11, the collar, the hook 9, the traction bow 2 and the puncture needle 1 to traction the patient's limb. The traction mechanism 7 drives the speed regulating mechanism 8 to work. After the speed regulating mechanism 8 is adjusted, it is fixed by the limiting mechanism 3. The speed regulating mechanism 8 synchronously drives the linkage mechanism 4 to work. The linkage mechanism 4 drives the timing mechanism 5 to adjust the required time for the corresponding recovery period. After the timing mechanism 5 finishes timing, the timing mechanism 5 will be connected to the traction mechanism 7, and then drive the transmission mechanism 6 to work through the work of the speed regulating mechanism 8. The transmission mechanism 6 drives the timing mechanism 5 and the traction mechanism 7 to work. The traction mechanism 7 reverses to gradually reduce the traction force on the patient.

[0018] Specifically, the traction mechanism 7 includes a vertical plate 71, a handle 72, a rotating disk 73, an engagement disk 74, a traction wheel 75 and a screw 76. The vertical plate 71 is fixedly arranged on the top of the mounting plate 16, the rotating disk 73 is rotatably arranged on the vertical plate 71, the handle 72 is fixedly arranged at the center of the rotating disk 73, the screw 76 is rotatably arranged on the second fixed plate 18, the traction wheel 75 is fixedly arranged at one end of the screw 76, the two ends of the second traction rope are respectively fixed to the traction wheel 75 and the bottom of the dynamometer 14, the engagement disk 74 is fixedly arranged on the traction wheel 75, and the engagement disk 74 and the rotating disk 73 are mutually engaged for transmission. The rotating disk 73 is driven to rotate by rotating the handle 72, and the rotating disk 73 drives the engagement disk 74 and the traction wheel 75 to rotate synchronously, and the rotation of the traction wheel 75 causes the second traction rope to be rolled up, thereby achieving the effect of traction of the patient's limbs; the setting of the dynamometer 14 is realized, and the traction force can be observed and adjusted more intuitively and accurately, and the operation is simple, convenient and fast.

[0019] Specifically, the speed regulating mechanism 8 includes a first bevel gear 81, two baffles 82, a first rotating shaft 83, a first telescopic plate 84, a driving motor 85, two inclined slots 86, a plug-in rod 87, an L-shaped sleeve rod 88, a second bevel gear 89, an L-shaped connecting plate 810, two sliding shafts 811 and a contact plate 812. The first rotating shaft 83 is rotatably arranged on the second fixed plate 18, the first bevel gear 81 is fixedly arranged at the end of the first rotating shaft 83, the two baffles 82 are fixedly arranged on the top of the fixed plate, and the two inclined slots 86 are arranged on the two baffles 82. The contact plate 812 is meshingly sleeved on the screw rod 76, one end of the plug-in rod 87 is fixedly set on the contact plate 812, and the L-shaped sleeve rod 88 is movably sleeved on the other end of the plug-in rod 87. The two sliding shafts 811 are respectively slidably set inside the two inclined grooves 86, the first telescopic plate 84 is fixedly set between the two sliding shafts 811, the driving motor 85 is fixedly set on the first telescopic plate 84, the L-shaped connecting plate 810 is fixedly set on the end of the output shaft of the driving motor 85, and the second bevel gear 89 is fixedly set on the L-shaped connecting plate 810. The screw rod 76 is rotated to drive the contact plate 812 to move, and the movement of the contact plate 812 drives the plug rod 87 to move, and the movement of the plug rod 87 drives the sleeve rod to move synchronously. It is worth mentioning that: at this time, the sleeve rod is in the shortest state, so it can move synchronously with the plug rod 87, and the movement of the sleeve rod drives the first telescopic plate 84 to move, and the movement of the first telescopic plate 84 drives the slide bar to move along the inclined groove 86, thereby driving the L-shaped connecting plate 810 and the second bevel gear 89 to move synchronously, so that the greater the traction force, the greater the transmission ratio of the second bevel gear 89 to the first bevel gear 81, so that the speed at which the traction force decreases is slower, which can ensure that the fracture can be slowly fitted during recovery and accelerate healing, and can also automatically and adaptively adjust the speed at which the traction force decreases according to the severity of the patient's fracture. No manual operation is required, the degree of automation is high, and no supervision is required, which is convenient and fast.

[0020] Specifically, the limiting mechanism 3 includes a plurality of limiting plates 31, a wedge block 32, a resisting spring 33, a sliding plate 34, a T-shaped plate 35 and a limiting groove 36. The plurality of limiting plates 31 are fixedly arranged between two baffle plates 82. The wedge block 32 is fixedly arranged on one side of the L-shaped sleeve rod 88 close to the limiting plate 31. The first telescopic plate 84 is hollow. The resisting spring 33 is arranged inside the first telescopic plate 84. The sliding plate 34 is fixedly arranged at the bottom of the resisting spring 33. The T-shaped plate 35 is fixedly arranged at one end of the wedge block 32. The limiting groove 36 is arranged on the sliding plate 34. When the L-shaped sleeve rod 88 moves to drive the wedge block 32 to move synchronously, while the wedge block 32 moves and inserts into the limiting groove 36, the inclined surface of the wedge block 32 abuts against the top of the limiting groove 36, thereby driving the sliding plate 34 to rise. When the sleeve rod no longer moves towards the direction of the wedge block 32 and the device is in a state of gradually decreasing traction force, the abutting disc 812 drives the plugging plate to move towards the direction of the traction wheel 75, so that the sleeve rod loses the abutment of the plugging rod 87, and thus the sliding plate 34 moves under the action of the resisting spring 33. The sliding plate 34 moves downward to abut against the wedge block 32 and the L-shaped sleeve rod 88 to move towards the direction of the plugging rod 87. At this time, the sliding plate 34 moves downward and inserts between the corresponding absorbing plates to limit the first telescopic plate 84 and the second bevel gear 89; it realizes automatically fixing the positions of the first bevel gear 81 and the second bevel gear 89 after adjusting the traction force. And due to the arrangement of the plugging rod 87 and the L-shaped sleeve rod 88, when the driving motor 85 drives the second bevel gear 89 to drive the first bevel gear 81 to rotate and the traction force gradually decreases, the initial fixed transmission ratio can be kept unchanged without manual intervention, and the degree of automation is high.

[0021] Specifically, the linkage mechanism 4 includes a first L-shaped rack 41, a linkage gear 42 and a second L-shaped rack 43. The linkage gear 42 is rotatably arranged on the top of the mounting seat. The first L-shaped rack 41 and the second L-shaped rack 43 are both slidably arranged on the top of the mounting seat, and the first L-shaped rack 41 abuts and cooperates with the abutting disc 812. When the abutting disc 812 moves to abut against the second L-shaped rack 43 to move, the second L-shaped rack 43 moves to drive the linkage gear 42 to rotate, and the linkage gear 42 rotates to drive the first L-shaped rack 41 to move; it realizes automatically adjusting the length of the recovery period according to the magnitude of the traction force.

[0022] Specifically, the timing mechanism 5 includes a timing cylinder 51, a timing column 52, a rotating ring 53, a triangular block 54, a one-way valve 55, a timing spring 56, a toothed plate 57, a fixed disk 58, a rotating disk 59, a toothed ring 510, two arc-shaped grooves 511 and a triangular groove 512. The timing cylinder 51 is fixedly arranged on the first fixing plate 17. The one-way valve 55 is arranged at the end of the timing cylinder 51. The timing spring 56 is arranged inside the timing cylinder 51. The timing column 52 is inserted and arranged inside the timing cylinder 51. The rotating ring 53 is rotatably sleeved on the timing column 52. The rotating ring 53 is fixedly connected to the first L-shaped rack 41. The toothed plate 57 is fixedly arranged on the first L-shaped rack 41. A circular hole is arranged on the side wall of the timing cylinder 51. The fixed disk 58 is fixedly arranged in the circular hole. The rotating disk 59 is rotatably arranged concentrically on the fixed disk 58. The two arc-shaped grooves 511 are respectively arranged on the rotating disk 59 and the fixed disk 58. The toothed ring 510 is fixedly arranged on the rotating disk 59. The triangular groove 512 is arranged on the meshing disk 74. The movement of the first L-shaped rack 41 drives the rotating ring 53 and the timing column 52 to move synchronously towards the direction of the timing cylinder 51. The movement of the first L-shaped rack 41 drives the toothed plate 57 to move. The movement of the toothed plate 57 drives the toothed ring 510 and the rotating disk 59 to rotate, so that the two arc-shaped grooves 511 are misaligned. The greater the traction force, the more the corresponding arc-shaped grooves 511 are misaligned, and the smaller the gap between the two arc-shaped grooves 511. The smaller the gap, the slower the gas inside the corresponding timing cylinder 51 enters, so that the speed at which the timing spring 56 pushes the timing column 52 to reset is slower. It realizes automatically adjusting the recovery period time according to the magnitude of the traction force, and drives the rotating ring 53, the first L-shaped rack 41 and the toothed plate 57 to reset synchronously while the timing spring 56 drives the timing column 52 to reset. When the toothed plate 57 resets, the misaligned arc-shaped grooves 511 gradually coincide and the gap gradually increases, so that the resistance of the timing spring 56 pushing the timing column 52 to move decreases, making the recovery period time conform to the situation that the recovery speed of the patient during the recovery period gradually accelerates.

[0023] Specifically, the transmission mechanism 6 includes a first transmission belt 61, a first transmission shaft 62, a second transmission belt 63, a first transmission wheel 64, and a second transmission wheel 65.

The first transmission wheel 64 is fixedly arranged at the end of the first transmission shaft 62. The second transmission belt 63 is sleeved on the first transmission wheel 64 and the second transmission wheel 65. The rotation of the first rotating shaft 83 drives the first transmission belt 61 to drive the rotation of the first transmission shaft 62. The rotation of the first transmission shaft 62 drives the rotation of the first transmission wheel 64. The rotation of the first transmission wheel 64 drives the second transmission belt 63 to drive the rotation of the second transmission wheel 65. The rotation of the second transmission wheel 65 drives the timing column 52 and the triangular block 54 to rotate synchronously. When the triangular block 54 is inserted into the triangular groove 512, it drives the traction wheel 75 to continuously reduce the traction force.
