Description

Technical Field

[0001] The present invention relates to the technical field of bone injury reduction frames, and specifically to a bone injury traction reduction frame for orthopedic doctors. Background Art

[0002] In modern medicine, for fractures and deformities in orthopedics, most require the assistance of a traction frame to reduce the bones. Especially in the correction of lower limb orthopedics, most often the patient's leg is positioned on a traction device, and the traction device rotates to traction the patient's leg, thereby correcting the misaligned bones.

[0003] However, in existing traction devices, the support frames for supporting the patient's legs are mostly integral. Generally, they are long strip-shaped support columns arranged under the patient's legs. When performing bone correction, the rotation points of the support columns are fixed and single. During actual bone correction, the entire support column rotates with the traction device, so that the entire patient's leg will bend or rotate with the traction force. This makes it impossible to accurately traction the patient's leg bones according to the misaligned points of the patient's bones during the correction process, resulting in limited operation accuracy and great operation difficulty. Moreover, in order to achieve smooth bone correction, the patient's position may need to be continuously adjusted during the operation so that the force application point of the traction device can accurately fall on the misaligned point of the patient's bone. Summary of the Invention

[0030] 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 making creative efforts belong to the scope of protection of the present invention.

[0031] Please refer to Figures 1 - 8, the present invention provides a technical solution: an orthopedic traction reduction frame for orthopedic doctors, including a support frame 1. There are two groups of support frames 1 which are arranged in parallel. A traction frame is movably arranged on the support frame 1. The traction frame can fix the patient's feet and can slide on the support frame 1. The support frame 1 is composed of multiple groups of support units 15 spliced end to end. Between adjacent support units 15, there are:

[0032] A connecting component that rotatably connects adjacent support units 15. The connecting component can enable multi-angle rotation between adjacent support units 15;

[0033] A limiting component that is located between adjacent support units 15 and is arranged around the outside of the connecting component. The limiting component can lock the relative positions of adjacent support units 15;

[0034] On one side of the edge support unit 15, there is an installation component that can connect the support frame 1 to the medical bed.

[0035] During operation, in the present invention, the support frame 1 is fixed on the medical bed body through the installation component. When correcting the gap between bones, the patient lies on the medical bed, with both legs placed on the two groups of support frames 1 arranged in parallel. The patient's feet are fixed on the traction frame. The position and height of the traction frame on the support frame 1 can be adjusted. The patient's legs can be tractioned through the traction frame. In the present invention, the support frame 1 is composed of multiple groups of support units 15 spliced together. When the limiting component is between the support units 15, the support units 15 are spliced into a fixed long column to support the patient's legs. When the limiting component is removed from between the support units 15, the corresponding support units 15 can rotate at multiple angles. In this way, when the traction frame traction the patient's legs, relative rotation can occur between the support units 15 where the limiting component is removed, so that the patient's leg bones on the support frame 1 at this position can be accurately rotated under the traction of the traction frame. In this way, during bone correction, the patient can specifically remove the limiting component according to the bone dislocation point, so that during the traction action of the traction frame, the force can be accurately applied to the patient's bone dislocation point, increasing the efficiency and accuracy of bone correction and reduction. Moreover, the rotation points of the support frame 1 can be freely adjusted by disassembling and installing the limiting component, which is convenient for medical staff to adjust according to the bone dislocation point and body proportion, avoiding the trouble of adjusting the patient's position during the bone reduction process.

[0036] As a further solution of the present invention, the traction frame includes a movable ring 4, the movable ring 4 is sleeved outside the support frame 1, both sides of the movable ring 4 are slidably connected with mounting frames 5, an upper mounting seat 6 is fixedly installed at the upper end of the mounting frame 5, a rotating rod 11 is rotatably installed at the upper end of the upper mounting seat 6, a connecting ring 9 is fixedly installed at the upper end of the rotating rod 11, a threaded rod 7 is threadedly connected inside the connecting ring 9, a foot fixing member 10 is rotatably installed at one end of the threaded rod 7, and a rocker 8 is fixedly installed at the other end of the threaded rod 7.

[0037] During operation, when bone fracture reduction is performed in the present invention, the patient's foot is fixed on the foot fixing member 10 through a strap. After fixation, the distance of the foot on the support frame 1 can be adjusted through the movable ring 4, and the height between the patient's foot and the support frame 1 can be adjusted through the mounting frame 5. Through the movement of the movable ring 4 and the mounting frame 5, the lower limbs of the patient can be relatively stretched and tractioned. For slight dislocation of the corresponding bones, the reduction of the bones can be completed through the movement of the movable ring 4 and the mounting frame 5. Moreover, by rotating the rocker 8, the threaded rod 7 can be driven to rotate. Through the interaction between the threaded rod 7 and the connecting ring 9, the lateral distance between the foot fixing member 10 and the mounting frame 5 can be adjusted. By pushing the foot fixing member 10 close to the patient's upper limb, the patient's leg can be bent upwards towards the upper body to perform bone reduction. In addition, the rotating rod 11 can rotate on the upper mounting seat 6 to drive the foot fixing member 10 to rotate left and right relative to the support frame 1, thereby driving the patient's leg bones to rotate relative to the pelvic joint to repair the bone dislocation at this place.

[0038] As a further solution of the present invention, side positioning members 22 are rotatably arranged at both sides of the movable ring 4 corresponding to the positions of the mounting frames 5. The side positioning members 22 can fix the positions of the mounting frames 5 and the movable ring 4. A lower connecting seat 12 is fixedly installed at the lower end of the mounting frame 5, a positioning rod 13 is rotatably installed on the lower connecting seat 12, and the upper end of the positioning rod 13 can pass through the movable ring 4 and abut against the surface of the support frame 1. An adjusting wheel 14 is arranged at the position of the lower connecting seat 12 corresponding to the positioning rod 13, and the adjusting wheel 14 can lock the positioning rod 13.

[0039] During operation, after the movable ring 4 moves, the side positioning member 22 can be rotated to approach the surface of the support frame 1 to fix the position of the movable ring 4. By rotating the adjusting wheel 14 on the positioning rod 13, the positioning rod 13 can be driven to pass through the movable ring 4 and approach the surface of the support frame 1, thereby fixing the position of the movable ring 4 on the support frame 1.

[0040] As a further solution of the present invention, main positioning grooves 29 and secondary positioning grooves 30 are respectively arranged at both ends of the support unit 15, and limiting grooves 28 are arranged at the positions of both ends of the support unit 15 corresponding to the positions between the main positioning grooves 29 and the secondary positioning grooves 30.

[0041] During operation, in the present invention, relative rotation space is reserved for adjacent support units 15 through the main positioning groove 29 and the secondary positioning groove 30, ensuring that adjacent support units 15 can rotate in multiple directions and at multiple angles.

[0042] As a further aspect of the present invention, the connection assembly includes a spherical seat 24, which is rotatably installed at one end of the support unit 15 close to the main positioning groove 29. One end of the spherical seat 24 is located outside the support unit 15 and fixedly installed with a threaded sleeve 26. An inner connection ball 25 is rotatably installed at one end of the support unit 15 close to the secondary positioning groove 30. One end of the inner connection ball 25 close to the secondary positioning groove 30 is fixedly installed with an installation screw 27, and the installation screw 27 can be threadedly connected to the threaded sleeve 26.

[0043] During operation, in the present invention, adjacent support units 15 are connected through the threaded sleeve 26 and the installation screw 27. The main positioning grooves 29 and the secondary positioning grooves 30 of adjacent support units 15 are arranged adjacent to each other. Then, the installation screw 27 is threadedly connected into the threaded sleeve 26, thereby rotatably connecting the support units 15. When the device needs to be stored, the support frame 1 can be disassembled into multiple support units 15 and then stored to reduce the storage space of the device and facilitate the transportation of the device.

[0044] As a further aspect of the present invention, the limiting assembly includes a main positioning block 19, a secondary positioning block 20, and a limiting plate 18. Four groups of main positioning blocks 19, secondary positioning blocks 20, and limiting plates 18 are provided between adjacent support units 15. The main positioning block 19 and the secondary positioning block 20 can be respectively inserted into the main positioning groove 29 and the secondary positioning groove 30. The limiting plate 18 fits with the limiting groove 28. Four groups of main positioning blocks 19 and secondary positioning blocks 20 between adjacent support units 15 are evenly distributed at the middle positions of the four side walls of the support unit 15. The limiting plate 18 is located between adjacent main positioning blocks 19 and secondary positioning blocks 20 and covers the outer surfaces of the main positioning blocks 19 and the secondary positioning blocks 20.

[0045] During operation, in the present invention, after the support units 15 are connected, the main positioning block 19 and the secondary positioning block 20 are respectively inserted into the main positioning groove 29 and the secondary positioning groove 30 between the support units 15. The main positioning block 19 and the secondary positioning block 20 on each side wall of the support unit 15 serve as limits, thereby restricting the relative rotation of the support units 15. Then, the limiting plate 18 covers the surfaces of the main positioning block 19 and the secondary positioning block 20, so that the main positioning block 19 and the secondary positioning block 20 can be fixed between the support units 15.

[0046] As a further solution of the present invention, magnetic blocks one are provided at positions corresponding to the main positioning groove 29 and the secondary positioning groove 30 at both ends of the support unit 15. Magnetic blocks two are also fixedly installed in the main positioning block 19 and the secondary positioning block 20.

Bolt holes are provided at both ends of the mounting plates 17. Bolt holes are also provided at corresponding positions at both ends of the support unit 15. Holding holes 21 are provided at the middle positions of the main positioning block 19 and the secondary positioning block 20.

[0047] During operation, in the present invention, the connection between the main positioning block 19 and the secondary positioning block 20 and the main positioning groove 29 and the secondary positioning groove 30 is made more stable and firm by the magnetic block one and the magnetic block two. Then, the mounting plate 17 is spanned between adjacent support units 15 through the cooperation of bolts and bolt holes, so that the limiting plate 18 can stably cover the surfaces of the main positioning block 19 and the secondary positioning block 20.

[0048] As a further solution of the present invention, four groups of threaded seats 16 are symmetrically arranged on one side surface of the support unit 15.

[0049] During operation, in the present invention, the removed main positioning block 19 and secondary positioning block 20 can be arranged above the support unit 15 through the limiting screw 23, so that the main positioning block 19 and the secondary positioning block 20 can cover the upper part of the patient's leg as a limiting ring. Thus, the upper and lower limbs of the adjacent support units 15 connected by rotation are fixed, ensuring that the patient's lower limb can be forcefully reset with the relative rotation of the support unit 15.

[0050] As a further solution of the present invention, the installation assembly includes a rotating shaft 2. The rotating shaft 2 is rotatably connected to the end of the edge support unit 15. Limiting members 3 are threadedly connected to the upper and lower ends of the rotating shaft 2.

[0051] During operation, in the present invention, the rotating shaft 2 can be rotated through the installation hole of the medical bed, and then the limiting member 3 is rotatably connected to both ends of the rotating shaft 2 to fix the rotating shaft 2 on the medical bed. And the lower limiting member 3 rotates and extends as the bottom support of the support frame 1.
