Description

Technical Field

[0001] The utility model relates to the technical field of orthopedic traction frames, in particular to a traction frame. Background Art

[0002] In orthopedic surgeries such as shoulder arthroscopy, in order to obtain a good surgical field of view and facilitate surgical operations, a traction frame is required to maintain the abduction design requirements of the affected limb.

[0003] The traction frame for shoulder arthroscopy surgery pulls the arm upward through counterweights and traction ropes. Due to the difference in weight between the arms and legs, the counterweight of the traction frame is insufficient when pulling the legs, and multiple counterweights need to be connected in series. However, the counterweights in series will be unstable, resulting in a poor user experience. As a result, the traction frame for shoulder arthroscopy surgery can only pull the arms, and cannot meet the emergency traction needs of the legs when the number of traction frames for the legs is insufficient, and the usage conditions are relatively simple. Summary of the invention

[0004] The disclosed embodiment relates to a traction frame, in which a traction rope and a counterweight are cooperated to pull the arms and other parts of the body, and the traction rope is wrapped around the outside of a winding disk, which completes the fixing of the position of the traction rope for pulling the legs, thereby avoiding the situation where the legs are heavy and one counterweight is not enough and multiple counterweights are connected in series and are unstable, thereby ensuring stable traction of the legs.

[0032] A lower fixing frame 2 is fixed to the lower part of the main fixing rod 1, a side connecting rotating column 201 is fixed to the outer side of the middle part of the lower fixing frame 2, the side connecting rotating column 201 is rotatably connected to a winding disk 202, an outer fixing column 203 is fixed to the outer side of the middle part of the winding disk 202, an outer limiting block 204 is arranged in a circular array outside the winding disk 202, a side connecting sliding rod 206 is slidably connected to the upper part of the side connecting rotating column 201, the top of the side connecting sliding rod 206 is rotatably connected to the outer limiting frame 205, an upper traction rod 3 is fixed to the top of the main fixing rod 1, and an upper slide cylinder 3 is slidably arranged outside the upper traction rod 3 01, a lower pulley 302 is rotatably provided at the lower part of the upper slide 301, a front extension frame 303 is slidably provided on the inner side of the upper traction rod 3, the lower pulley 302 is rotatably connected with the traction rope 305, the tail end of the traction rope 305 is hooked and hung with the counterweight 304, a tightening screw 104 is screwed on the upper or middle part of the upper slide 301, the tightening screw 104 of the upper slide 301 is tightened with the upper traction rod 3, the position of the upper slide 301 is adjusted, the traction position of the traction rope 305 is adjusted by the upper slide 301, and a lower connecting seat 4 is arranged below the lower fixed frame 2.

[0033] In the disclosed embodiment, the side connecting slide bar 206 is engaged with the outer limit block 204 on the outer side of the winding disk 202. When the side connecting slide bar 206 and the outer limit block 204 are engaged, the winding disk 202 cannot rotate, and the winding disk 202 completes the position fixing of the traction rope 305 for traction of the legs, thereby avoiding the situation where the legs are heavy and one counterweight block 304 is not enough and multiple counterweight blocks 304 are unstable in series, thereby improving the compatibility with the arms and legs.

[0034] In the embodiment of the present disclosure, the front end of the front extension frame 303 is rotated with a lower pulley 302, and the tightening screw 104 screwed on the front end of the upper traction rod 3 is tightened against the front extension frame 303. The range adjustment is performed through the front extension frame 303 to adapt to the changes in the traction range of the arms and legs, meet the needs of adjusting the changes in the traction range of the arms and legs, improve the compatibility with the arms and legs, and meet the stable use of traction for the legs.

[0035] Embodiment 2, on the basis of embodiment 1, an extension rod is slidably arranged on the upper part of the main fixing rod 1, a hole is set on the main fixing rod 1 and a hole of the extension rod is aligned with a pin for connection and fixation, the top of the extension rod is fixedly connected to the upper traction rod 3, and the overall height is adjusted by sliding the extension rod through the main fixing rod 1. When not in use, the extension rod and the main fixing rod 1 are highly compressed to reduce space occupancy and facilitate transportation.

[0036] The working principle of this embodiment is as follows: when not in use, the main fixing rod 1 is connected to the middle cross bar of the lower connecting seat 4 through the lower U-shaped connecting frame 103 and fixed by the tightening screw 104. The main fixing rod 1 moves along the ground with the bottom pulley of the lower connecting seat 4, and the counterweight block 304 can be placed inside the lower connecting seat 4. When it is needed, the main fixing rod 1 is slidably inserted through the lower U-shaped connecting frame 103 and the outer cross bar of the operating bed on which the person lies, and the lower U-shaped connecting frame 103 is tightened against the operating bed by the tightening screw 104. The crossbar outside the bed is fixed. Shoulder arthroscopy surgery requires traction of the arm to lift the arm. When traction of the arm is performed, the arm is first wrapped in a traction connection bag, and then the front and rear parts of the connection bag are hooked and connected by multiple connection hooks at the head end of the traction rope 305, and then the counterweight 304 is hung and placed at the tail end of the traction rope 305. The traction rope 305 forms an L-shaped path along multiple lower pulleys 302, and the traction rope 305 and the counterweight 304 cooperate to pull the arm and other parts to a higher height;

[0037] When heavier leg traction is performed, the connecting hook at the tail end of the traction rope 305 hooks the external fixing column 203, and the personnel pushes the winding disk 202 to rotate through the external fixing column 203, and the external limit block 204 and the external limit frame 205 are separated and contacted and fixed, and the winding disk 202 rotates, and the traction rope 305 is wrapped around the outside of the winding disk 202. After the traction rope 305 pulls the leg to a suitable position, the external limit block 204 and the external limit frame 205 engage to fix the position of the winding disk 202, and the winding disk 202 cannot continue to rotate. The winding disk 202 completes the position fixation of the traction rope 305 for leg traction, avoiding the situation that the leg position is heavy and one counterweight block 304 is not enough and multiple counterweight blocks 304 are connected in series and are unstable. The side connecting rotating column 201 is rotated at the same time and multiple winding disks 202 are set to achieve adjustment of multiple traction ropes 305;

[0038] The front extension frame 303 and the upper traction rod 3 are slid to extend their lengths, and the tightening screws 104 of the upper traction rod 3 tighten the front extension frame 303 to fix the position of the upper traction rod 3. The range is adjusted through the front extension frame 303 to adapt to the changes in the range of traction of the arms and legs and meet the needs of adjusting the traction range of the arms and legs. When not in use, the front extension frame 303 slides to the inside of the upper traction rod 3 to shorten the length and improve the passability of the upper traction rod 3 when moving indoors.
