Description

Technical Field

[0001] This invention relates to the field of orthopedic traction frame technology, specifically an adjustable orthopedic traction frame with angle locking. Background Technology

[0002] In orthopedic clinical treatment, orthopedic traction frames are important auxiliary devices used to treat leg fractures, joint dislocations, and other conditions. They mainly apply stable traction to the leg to help restore bone position, relieve soft tissue compression, and create favorable conditions for subsequent healing.

[0003] Currently, most commonly used orthopedic traction frames fix one end of the traction rope to the leg binding structure and the other end to the traction frame or external fixation point when applying traction to the legs. The traction direction is usually diagonally upward, which is inconsistent with the natural length direction of the leg. At the same time, since the legs will move to some extent due to posture adjustments when the body is lying in bed, the fixed end of the traction rope cannot be adjusted with the movement of the legs. After the legs move, the angle between the legs and the traction rope changes, and the traction direction deviates further from the preset direction, thereby reducing the traction treatment effect. Moreover, when the deviation is too large, it may also cause additional compression or traction damage to the legs due to improper traction force direction.

[0004] Therefore, an adjustable orthopedic traction frame with angle locking is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an adjustable orthopedic traction frame with angle locking. Through the locking action of the first adjustment component and the locking component, the initial angle of the traction arm can be flexibly adjusted to adapt to different patients' leg postures and the relative position of the head of the bed. Combined with the cooperation of the first and second limiting sleeves in the second adjustment component, and the locking action of the second adjustment screw and the locking knob, dual fixation of the traction arm's angle and height is achieved, ensuring that the traction arm fits snugly against the leg and that the traction direction is consistent with the leg's length direction.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Please see Figures 1-10This embodiment of an adjustable orthopedic traction frame with angle locking includes a first adjustment component 1, a second adjustment component 2, a third adjustment component 3, and a constant force component 4. The first adjustment component 1 includes a fixed arm 101, an adjusting arm 102, and a traction arm 103. One end of the fixed arm 101 is used for fixing to the outside, and the other end of the fixed arm 101 is rotatably connected to the end of the adjusting arm 102. The other end of the adjusting arm 102 is rotatably connected to the traction arm 103. A locking component 5 is provided at the rotatable connection between the fixed arm 101 and the adjusting arm 102 for locking and fixing. The relative rotation of arm 101 and adjusting arm 102, and the connection between adjusting arm 102 and traction arm 103 through the second adjusting component 2, wherein the fixed arm 101 can be fixed by bolts, and the end of the fixed arm 101 used for external fixation is connected to the head of the bed by bolts. The rotational connection between the fixed arm 101 and adjusting arm 102, and between adjusting arm 102 and traction arm 103, allows the adjusting arm 102 to swing around the fixed arm 101 and the traction arm 103 to swing around the adjusting arm 102, thereby adapting to the relative tilt angle between the legs and the head of the bed of different patients, and thus making the traction arm 103 conform to the contour of the legs.

[0024] Locking assembly 5 includes a first locking knob 501, a first locking block 502, and a second locking block 503. The lower end of the first locking knob 501 passes through the fixed arm 101 and the adjusting arm 102. The first locking knob 501 is threadedly connected to the adjusting arm 102. The first locking block 502 is fixed to the surface of the adjusting arm 102, and the second locking block 503 is fixed to the surface of the fixed arm 101. The first locking block 502 and the second locking block 503 correspond to each other. The configuration is such that when locking block 1 (502) and locking block 2 (503) are not pressed, there is a gap between them and they do not contact each other. The fixed arm 101 and the adjusting arm 102 can rotate relative to each other. When the locking knob 501 is turned, it presses the upper surface of the fixed arm 101, causing locking block 1 (502) to fit against locking block 2 (503). After the locking knob 501 is tightened, the fixed arm 101 and the adjusting arm 102 are locked.

[0025] The second adjustment component 2 includes a second adjustment screw 201, a second adjustment knob 202, a second locking knob 203, a first limiting sleeve 204, a second limiting sleeve 205, and a second spring 206. The second adjustment screw 201 passes through the ends of the adjusting arm 102 and the traction arm 103. The second adjustment component 2 is used to adjust and lock the angle of the traction arm 103. At the same time, the second adjustment component 2 is used to adjust the height of the traction arm 103 relative to the fixed arm 101. The top of the first limiting sleeve 204 is inserted into the adjusting arm 102. Internally, the top of the first limiting sleeve 204 is rotatably connected to the adjusting arm 102 via a bearing. The second limiting sleeve 205 is fixedly installed on the upper surface of the traction arm 103. The outer side of the second limiting sleeve 205 is provided with a limiting piece 7. The first limiting sleeve 204 is provided with a limiting groove 8 corresponding to the limiting piece 7. The first limiting sleeve 204, the second limiting sleeve 205, and the second adjusting screw 201 are coaxial. When the traction arm 103 rotates, it drives the second limiting sleeve 205 to rotate around the screw, and the second limiting sleeve 205 drives the first limiting sleeve 204 to rotate around the screw. When the lead screw rotates, the second adjusting knob 202 is fixedly connected to the top of the second adjusting lead screw 201, and the second locking knob 203 is threadedly connected to the second adjusting lead screw 201. A fixing washer 9 is fixedly connected to the lower end of the second adjusting lead screw 201. The limit sleeve 205 and the end of the traction arm 103 are sleeved on the outside of the second adjusting lead screw 201, and the limit sleeve 205 and the traction arm 103 are slidably connected to the outer wall of the second adjusting lead screw 201. The limit sleeve 205 is inserted into the limit sleeve 1 204 and is in contact with the limit... The traction arm 103 is slidably connected to the 204 sleeve and can slide up and down along the screw. The end of the traction arm 103 is pressed against the fixed pad 9 by gravity. By rotating the second adjustment knob 202 and the second locking knob 203, the relative position of the second locking knob 203 and the second adjustment knob 202 can be adjusted, thereby adjusting the relative height of the traction arm 103 and the adjustment arm 102. Medical staff can adjust the height of the traction arm 103 by rotating the two knobs to change the extension length of the screw according to the height requirements.

[0026] The top surface of the limiting sleeve 204 is flush with the surface of the adjusting arm 102. A second locking block 10 is provided on the outer side of the adjusting arm 102 near the second adjusting screw 201. A second locking block 11 is provided on the surface of the limiting sleeve 204 near the adjusting arm 102. The second locking blocks 10 and 11 surround the second adjusting screw 201 and engage with the lower surface of the second adjusting knob 202. A second spring 206 is sleeved on the outside of the second adjusting screw 201. One end of the second spring 206 is inserted into the traction arm 103, and the other end is... When the fixed pad 9 comes into contact with the fixed pad, the traction arm 103 is pushed down by gravity, compressing the second spring 206. The second spring 206 then comes into contact with the fixed pad 9, causing the fixed pad 9 to push down the lead screw. The lead screw then causes the lower surface of the second locking knob 203 to adhere to the upper surface of the adjusting arm 102 and the first limiting sleeve 204. The second locking knob 203 simultaneously locks the first limiting sleeve 204 and the adjusting arm 102, preventing them from rotating relative to each other. The first limiting sleeve 204 is locked, and the rotation of the traction arm 103 is restricted by the second limiting sleeve 205, thus fixing the angle of the traction arm 103.

[0027] Adjustment component 3 includes adjustment screw 301, adjustment knob 302, constant force slider 303, slider adjustment knob 304, and adjustment block 305. Constant force component 4 includes constant force spring 401, adjustment knob 402, and friction plate 403. Adjustment screw 301 drives constant force slider 303 to slide along the traction arm 103. Constant force spring 401 is fixedly connected to one end of constant force slider 303. A friction plate 403 is fixedly installed on the side of constant force slider 303. The fixing bracket 6 for securing the leg has a third adjusting screw 301 inserted into the traction arm 103 along its length. A constant force slider 303 is slidably connected to a groove on the traction arm 103. The third adjusting screw 301 and the constant force slider 303 are threadedly connected. A third adjusting block 305 is located inside the constant force slider 303. The third adjusting block 305 has an internal thread corresponding to the external thread of the third adjusting screw 301 on its side near the third adjusting screw 301. When the No. 3 adjusting screw 301 is engaged, rotating the No. 3 adjusting knob 302 causes the No. 3 adjusting screw 301 to drive the constant force slider 303 to slide along the direction of the traction arm 103. The upper surface of the constant force slider 303 is provided with a movable slider 12. The No. 3 slider adjusting knob 304 is threadedly connected to the movable slider 12. The movable slider 12 is slidably connected to the constant force slider 303 along the moving direction of the constant force slider 303. The side of the No. 3 adjusting block 305 is provided with an arc-shaped groove 13, and a lifting mechanism slides within the arc-shaped groove 13. The lifting rod 14 is fixedly connected to the constant force slider 303 at both ends. The lifting rod 14 is used to lift the third adjusting block 305. The third adjusting block 305 meshes with the surface of the third adjusting screw 301. When the constant force slider 303 is pushed, the constant force slider 303 drives the lifting rod 14 to move. The lifting rod 14 moves along the arc groove 13 to lift the third adjusting slider, so that the surface of the third adjusting slider is disengaged from the third adjusting screw 301, thereby allowing the constant force slider 303 to slide along the traction arm 103.

[0028] The upper surface of the third adjusting block 305 is provided with a third adjusting spring 15. The other end of the third adjusting spring 15 is fixedly connected to a contact plate 16. The third adjusting block 305 is connected to the contact plate 16 through multiple guide rods. The lower end of the third slider adjusting knob 304 is inserted into the contact plate 16 and is rotatably connected to the contact plate 16. When the third adjusting block 305 is lifted, it needs to overcome the elastic force of the third adjusting spring 15. The third adjusting block 305 slides upward along the locking surface with the lead screw, and at the same time slides towards the contact plate 16 through the guide rod, and slides with the moving slider 12.

[0029] The constant force spring 401 is fixedly connected to the inner bottom surface of the traction arm 103 through the housing. The telescopic ends of multiple constant force springs 401 are fixedly connected to the end of the constant force slider 303. The fourth adjustment knob 402 and the friction plate 403 are both located on the side of the constant force slider 303 away from the fixed frame 6. The fourth adjustment knob 402 passes through the side of the constant force slider 303. The end of the fourth adjustment knob 402 is inserted into the friction plate 403 and is rotatably connected to the friction plate 403. The friction surface of the friction plate 403 is made of nylon and is in contact with the outer side of the constant force slider 303. The constant force spring 401 pulls the constant force slider 303 to apply a constant force to the constant force slider 303. The pulling force of the constant force spring 401 is a fixed magnitude. When the constant force spring 401 pulls the constant force slider 303, it needs to overcome the friction between the friction plate 403 and the traction arm 103. Rotating the fourth adjustment knob 402 can adjust the friction between the friction plate 403 and the traction arm 103.

[0030] In use, the person lies naturally on the bed with their legs tilted relative to the side of the bed. One end of the fixing arm 101 of the first adjustment component 1 is fixedly connected to the headboard with bolts. Then, the adjusting arm 102 and the traction arm 103 are swung to make the traction arm 103 fit against the person's legs. Then, the person's lower legs and ankles are fixed by the fixing frame 6. The fixing frame 6 has a support plate. The person's lower legs are placed on the support plate, and the feet are placed on the top of the fixing frame 6. The lower legs are fixed to the support plate with straps, and the feet are fixed to the top plate with straps. Locking component 5 locks the joint between the fixed arm 101 and the adjusting arm 102. Adjusting component 2 makes the lower part of the traction arm 103 fit against the bed surface and locks the joint between the traction arm 103 and the adjusting arm 102. Adjusting component 3 drives the constant force slider 303 to slide along the traction arm 103. Adjusting component 3 drives the fixing frame 6 to the position of the person's lower leg and foot for easy fixation. Constant force component 4 continuously applies a fixed force to pull the constant force slider 303.

[0031] Furthermore, after the leg is fixed by the traction arm 103, the direction of the leg is consistent with the direction of the traction arm 103. When a person lies down on the bed, they will slide along the direction of the bed. The leg drives the fixing frame 6 to slide along the direction of the traction arm 103. When the leg drives the fixing frame 6 to slide, the fixing frame 6 pushes the constant force slider 303 to move. When the constant force slider 303 moves, it lifts the third adjusting block 305, so that the third adjusting block 305 disengages from the lead screw. At this time, the constant force slider 303 can slide. When the leg pushes the constant force slider 303, the third adjusting block 305 re-adheres to the lead screw under the pressure of the spring. The sliding cooperation between the lifting rod 14 and the arc groove 13 prevents the leg from being subjected to hard traction when moving, avoiding additional damage. At the same time, the reset function of the third adjusting spring 15 ensures that the traction can still be carried out stably after movement.

[0032] The tension on the constant force slider 303 is the resultant force of the tension of the constant force spring 401, the friction force, and the resistance of the third adjusting block 305 relative to the lead screw. The friction force can be adjusted by the fourth adjusting knob 402, and the resistance of the third adjusting block 305 relative to the lead screw can be adjusted by the third slider adjusting knob 304. When the fourth adjusting knob 402 is turned, the tightness of the contact between the friction plate 403 and the traction arm 103 changes, and the friction force increases or decreases accordingly. When the third slider adjusting knob 304 is turned, the third adjusting spring 15 is compressed or released through the contact plate 16, changing the meshing tightness between the third adjusting block 305 and the third adjusting lead screw 301, thereby adjusting the resistance. Medical staff can adjust the traction force by coordinating these two knobs.
