Description

Technical Field

[0001] The present invention belongs to the technical field related to orthopedic traction, and more specifically, particularly relates to an adaptive orthopedic manipulator for fixed traction. Background Art

[0002] Traction is a commonly used treatment method in orthopedics, applying the principle of action and reaction. It counteracts the tension and retraction of soft tissues, enables the reduction of fractures and bone dislocations, and prevents and corrects deformities. Traction through an orthopedic manipulator can immobilize the affected limb, reduce local irritation and alleviate the spread of local inflammation, stabilize the fracture ends, facilitate fracture healing, and can also correct and prevent joint deformities caused by muscle spasms, relieve muscle spasms, improve venous blood return, and eliminate limb swelling. However, the existing orthopedic traction in the prior art has the following defects: In the prior art, when an orthopedic manipulator performs traction and extension on the bones of a human limb, it usually needs to first clamp the bones of the human limb. However, it is difficult for the orthopedic manipulator to quickly and stably clamp the bones of the human limb, thereby affecting the effect of traction and extension on the bones of the human limb.

[0003] In the prior art, when an orthopedic manipulator clamps and performs traction and extension on the bones of a human limb, due to the relatively simple structure for limiting and fixing the steel needle, it is difficult to quickly perform a sufficient limiting and fixing action on the steel needle, and the situation of steel needle displacement or shaking is likely to occur, thereby affecting the effect of the steel needle in clamping and fixing the bones of the human limb.

[0004] There is a Chinese patent with the application number CN201610410792.9, which discloses a portable traction device for orthopedics. The portable traction device for orthopedics of the present invention includes a traction body, a telescopic arm, a front C-arm, and a rear C-arm. The rear C-arm is connected to the traction body. A relatively telescopic telescopic arm is provided inside the traction body. The front C-arm is connected to the end of the telescopic arm extending outside the traction body. The front C-arm and the rear C-arm are arranged opposite to each other and cooperate with each other. The portable traction device for orthopedics of the present invention mainly solves the technical problem of precise control of human limb traction during surgery, treatment, and rehabilitation; enables doctors to clearly determine the traction distance during use, ensuring a relatively precise limb length for patients; and takes into account the issues of labor saving, torque increase, and efficiency, and strives to achieve the best fit in terms of labor saving, torque increase, and work efficiency improvement. However, during the traction process of this portable traction device, it is impossible to precisely control its traction and extension distance, greatly affecting the work efficiency.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an adaptive orthopedic manipulator for fixed traction is provided, with the expectation of achieving a more practical and valuable purpose. Summary of the Invention

By the contact between one side of the first guide block and the inclined surface of one side of the second guide block, the second guide block and the first push block are pushed to move. The first push block moves to push the arc-shaped splint and the steel needle to move, and the two arc-shaped splints approach each other to clamp and fix the human limb. Further, through the setting of an external thread ring, the two steel needles rotate to drive the two external thread rings to rotate respectively. By the contact between the outer side of the external thread ring and the internal thread of the first push block, the two steel needles approach each other.

Finally, through the settings of an arc-shaped plate, an elastic pressing plate, a second push block, and a guide groove, the first push block moves to drive the two second push blocks to move. By the inclined surfaces of a pair of guide grooves on the inner walls of the two second push blocks and the C-shaped seat, the two second push blocks approach each other; the two second push blocks approach each other to push the two arc-shaped plates and the elastic pressing plate to approach each other. The two arc-shaped plates and the elastic pressing plate approach each other to clamp and fix the steel needle, quickly and fully limit and fix the steel needle, avoid the displacement or shaking of the steel needle, and improve the clamping and fixing effect of the two steel needles on the bone of the human limb.

[0017] An adaptive orthopedic manipulator for fixed traction of the present invention, through the settings of a hydraulic cavity, a connection channel, a C-shaped water bag, and a piston plate, the C-shaped plate slides annularly to drive the piston plate to slide annularly in the hydraulic cavity.

[0018] An adaptive orthopedic manipulator for fixed traction according to the present invention, through the settings of a connecting block, an elastic sliding plate, and an elastic limiting plate, the movement of the second fixed frame drives the connecting block and the elastic sliding plate to move. The two ends of the elastic sliding plate are respectively in sliding contact with the mutually approaching sides of the two elastic limiting plates, and one end of the elastic sliding plate is in contact with the inclined surface on one side of the elastic limiting plate. Thus, during the process of the two clamping components approaching each other, the resistance received by the two second fixed frames continuously increases, so as to facilitate the two clamping components to approach each other smoothly, which is beneficial to accurately controlling the traction and telescopic distance thereof.

[0034] Preferably, referring to the appendix Figure 5, on one side of each second fixed frame 33, a push rod 44 is slidably arranged. One end of the push rod 44 is fixedly provided with a movable plate 45. On one side of the movable plate 45, a number of second clamping blocks 47 are fixedly arranged. On one side of the limiting frame 32 close to the direction of the movable plate 45, a number of second clamping grooves 48 are vertically arranged at intervals. Each second clamping block 47 slides inside the second clamping groove 48.

[0035] Preferably, referring to the attached Figure 5 , one side of each second clamping block 47 is in inclined contact with one side inside of the second clamping groove 48, the other side of each second clamping block 47 is in planar contact with the other side inside of the second clamping groove 48, and a spring 46 is connected between each movable plate 45 and the inside of the second fixed frame 33. Preferably, referring to the attached Figure 1 to the attached Figure 2 , on the outer sides of the two C-shaped seats 10, two fixing plates 49 are respectively fixedly arranged. A guide rod 50 is connected between the two fixing plates 49. The two ends of the two guide rods 50 are respectively in sliding contact with the two fixing plates 49. A compression spring 51 is connected between the two fixing plates 49. The compression spring 51 is located outside the guide rod 50.

[0036] The specific usage method of the present invention: The staff places the two clamping components on the human limb. Then, the two second stepping motors 40 are started. The start of the second stepping motor 40 drives the fourth gear 39 to rotate. Through the outer side of the third gear 38 being meshed with the outer side of the fourth gear 39, the C-shaped plate 15 slides annularly in the C-shaped seat 10. The annular sliding of the C-shaped plate 15 drives the two first guide blocks 25 to move. Through one side of the first guide block 25 being in inclined contact with one side of the second guide block 26, the second guide block 26 and the first push block 16 are pushed to move. The movement of the first push block 16 pushes the arc-shaped clamping plate 12 and the steel needle 14 to move. The two arc-shaped clamping plates 12 approach each other to clamp and fix the human limb.

[0037] Secondly, the staff rotates the two steel needles 14. The rotation of the two steel needles 14 respectively drives the two external thread rings 17 to rotate. Through the outer side of the external thread ring 17 being in threaded contact with the inside of the first push block 16, the two steel needles 14 approach each other. The two steel needles 14 approach each other and slide on the two arc-shaped clamping plates 12 respectively, so that the two steel needles 14 approach each other to clamp the bones of the human limb.

[0038] Next, the C-shaped plate 15 continues to slide annularly to drive the two first guide blocks 25 to move. By the contact between one side of the first guide block 25 and the inclined surface on one side of the second guide block 26, the second guide block 26 and the first push block 16 are pushed to move, and the movement of the first push block 16 drives the two second push blocks 20 to move. Through the inclined surfaces of the two second push blocks 20 and a pair of guide grooves 52 on the inner wall of the C-shaped seat 10, the two second push blocks 20 approach each other. The two second push blocks 20 approaching each other push the two arc-shaped plates 18 and the elastic pressing plate 19 to approach each other. The two arc-shaped plates 18 and the elastic pressing plate 19 approaching each other clamp and fix the steel needle 14, quickly and fully limit and fix the steel needle 14, avoiding the displacement or shaking of the steel needle 14, and improving the clamping and fixing effect of the two steel needles 14 on the bones of the human limb. Among them, the two arc-shaped plates 18 approaching each other respectively stretch the two elastic members 21 to generate elastic force, which is beneficial to the two arc-shaped plates 18 moving away from each other and resetting under the elastic force of the two elastic members 21.

[0039] At the same time, the annular sliding of the C-shaped plate 15 drives the piston plate 24 to slide annularly in the hydraulic chamber 23. The annular sliding of the piston plate 24 causes the solution in the hydraulic chamber 23 to enter the C-shaped water bag 11 through the connecting channel 30, and the C-shaped water bag 11 expands to fully support and fix the two arc-shaped clamping plates 12. And the staff rotates the bolt 27. By the threaded contact between the bolt 27 and the C-shaped seat 10, the bolt 27 moves. The movement of the bolt 27 drives the first clamping block 28 to enter the corresponding first clamping groove 29, and the C-shaped plate 15 is limited and fixed by the cooperation of the first clamping block 28 and the first clamping groove 29, which is beneficial to improving the stability of the two arc-shaped clamping plates 12 clamping and fixing the human limb and the stability of the two steel needles 14 clamping and fixing the bones of the human limb.

[0040] Finally, the first stepping motor 35 is started to drive the first gear 36 to rotate. By the outer side of the first gear 36 meshing with the outer side of the second gear 37, the double-threaded lead screw 34 rotates. Due to the opposite thread directions on the outer sides of the two ends of the double-threaded lead screw 34 and the two ends of the double-threaded lead screw 34 being respectively in threaded contact with the two second fixing frames 33, the two second fixing frames 33 approach each other. The two second fixing frames 33 approaching each other drive the two clamping assemblies to approach each other, and the two clamping assemblies approaching each other perform traction and expansion on the bones of the human limb.

[0041] Meanwhile, the movement of the second fixed frame 33 drives the connection block 41 and the elastic sliding plate 42 to move. The two ends of the elastic sliding plate 42 are respectively in sliding contact with the closer sides of the two elastic limit plates 43, and one end of the elastic sliding plate 42 is in contact with the inclined surface of one side of the elastic limit plate 43. Therefore, during the process of the two clamping assemblies approaching each other, the resistance received by the two second fixed frames 33 continuously increases, so as to facilitate the smooth approach of the two clamping assemblies to each other and is conducive to precisely controlling the traction and telescopic distance thereof. Moreover, as the two second fixed frames 33 approach each other, one side of the second clamping block 47 is in contact with the inclined surface of the inner side of the second clamping groove 48, so that the second clamping block 47 and the movable plate 45 move. The movement of the movable plate 45 stretches the spring 46 to generate an elastic force, so that the two second fixed frames 33 can approach each other smoothly. Then, the other side of the second clamping block 47 is in contact with the flat surface of the other inner side of the second clamping groove 48, so as to play a role in limiting and fixing the mutual separation of the two second fixed frames 33, so as to further precisely control the traction and telescopic distance thereof.

[0042] Meanwhile, the approach of the two clamping assemblies drives the two fixing plates 49 to approach each other. The two fixing plates 49 are respectively in sliding contact with the two ends of the guide rod 50, so as to guide the two clamping assemblies and prevent displacement or inclination during the approach of the two clamping assemblies. Moreover, as the two fixing plates 49 approach each other, the compression spring 51 is compressed to generate an elastic force. Therefore, under the elastic force of the compression spring 51, the resistance received during the approach of the two clamping assemblies continuously increases, which is conducive to the smooth approach of the two clamping assemblies to each other.

[0043] The present invention provides a fixed traction adaptive orthopedic manipulator. Through the arrangement of the first guide block 25, the second guide block 26, the first push block 16, the arc-shaped splint 12, and the steel needle 14, the C-shaped plate 15 slides in an annular manner to drive the two first guide blocks 25 to move. Through the contact between one side of the first guide block 25 and the inclined surface of one side of the second guide block 26, the second guide block 26 and the first push block 16 are pushed to move. The movement of the first push block 16 drives the arc-shaped splint 12 and the steel needle 14 to move. The two arc-shaped splints 12 approach each other to clamp and fix the human limbs. Through the arrangement of the external thread ring 17, the two steel needles 14 rotate and respectively drive the two external thread rings 17 to rotate. Through the contact between the outer side of the external thread ring 17 and the internal thread of the first push block 16, the two steel needles 14 approach each other. The two steel needles 14 approach each other and slide on the two arc-shaped splints 12 respectively, so that the two steel needles 14 approach each other to clamp and fix the bones of the human limbs.

[0044] The present invention provides a fixed traction adaptive orthopedic manipulator, through the arrangement of a hydraulic chamber 23, a connecting channel 30, a C-type water bag 11, and a piston plate 24. The annular sliding of the C-type plate 15 drives the piston plate 24 to slide annularly in the hydraulic chamber 23. The annular sliding of the piston plate 24 allows the solution in the hydraulic chamber 23 to enter the C-type water bag 11 through the connecting channel 30. The expansion of the C-type water bag 11 fully supports and fixes the two arc-shaped splints 12, which is beneficial to improving the stability of the two arc-shaped splints 12 in clamping and fixing the human limbs. Then, through the arrangement of the bolt 27, the first clamping block 28, and the first clamping groove 29, the staff rotates the bolt 27, and the bolt 27 is in threaded contact with the C-shaped seat 10, thereby moving the bolt 27; the movement of the bolt 27 drives the first clamping block 28 to enter the corresponding first clamping groove 29, and the first clamping block 28 cooperates with the first clamping groove 29 to limit and fix the C-shaped plate 15, which is beneficial to improve the stability of the two arc-shaped splints 12 in clamping and fixing the human limbs and the stability of the two steel needles 14 in clamping and fixing the bones of the human limbs.

[0045] An adaptive orthopedic manipulator for fixed traction according to the present invention, through the settings of the connecting block 41, the elastic slide plate 42, and the elastic limit plate 43, the movement of the second fixed frame 33 drives the connecting block 41 and the elastic slide plate 42 to move. The two ends of the elastic slide plate 42 are respectively in sliding contact with the mutually approaching sides of the two elastic limit plates 43, and one end of the elastic slide plate 42 is in contact with the inclined surface on one side of the elastic limit plate 43. Thus, during the process of the two clamping components approaching each other, the resistance received by the two second fixed frames 33 continuously increases, so as to facilitate the smooth approach of the two clamping components to each other and is beneficial to precisely controlling the traction and telescopic distance thereof. Further, through the settings of the movable plate 45, the spring 46, the second clamping block 47, and the second clamping groove 48, the two second fixed frames 33 approach each other. One side of the second clamping block 47 is in contact with the inclined surface on the inner side of the second clamping groove 48, so that the second clamping block 47 and the movable plate 45 move. The movement of the movable plate 45 stretches and retracts the spring 46 to generate an elastic force, so that the two second fixed frames 33 can approach each other smoothly. Then, the other side of the second clamping block 47 is in contact with the flat surface on the other inner side of the second clamping groove 48, so as to play a role in limiting and fixing the mutual separation of the two second fixed frames 33, so as to further precisely control the traction and telescopic distance thereof.
