Technical Field
[0001] The utility model relates to the technical field of traction frames, in particular to a traction frame for lower limb injuries. Background Art
[0002] Lower limb trauma is relatively common in surgery. Usually some more serious lower limb trauma is accompanied by bone damage of the lower limb. When treating such patients, in addition to necessary debridement, the patient's lower limbs are generally covered with plaster boards and suspended to keep the lower limbs upright to avoid joint movement leading to lower limb movement and affecting the recovery of the lower limbs.
[0003] At present, the patient's lower limbs are mainly suspended by bandage wrapping and tape fixing, so that the lower limbs are pulled. Due to the need for bandage wrapping, the skin's air permeability is poor, which can easily cause discomfort to the patient, and the traction intensity cannot be adjusted according to the patient's needs. Maintaining a traction height for a long time can easily cause lower limb fatigue. Therefore, a lower limb trauma traction frame is needed to meet people's needs. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] Example 1: Reference Figure 1-4A lower limb trauma traction frame, comprising an L-shaped plate 1, a first traction frame 2 is installed on the L-shaped plate 1, a reel 3 is rotatably installed in the first traction frame 2, a reel 4 is installed on the reel 3, a traction belt 5 is installed on the reel 4, a second traction frame 6 is installed on the L-shaped plate 1, a rotating shaft 7 is rotatably installed in the second traction frame 6, a guide wheel 8 is installed on the rotating shaft 7, the rotating shaft 7 is movably installed on the guide wheel 8, a traction frame 9 is installed on the traction belt 5, a first fixing ring 10 and a second fixing ring 11 are movably installed in the traction frame 9, and a first fixing screw 1 is rotatably installed in the traction frame 9 2, a second fixing screw 13 is installed on the first fixing screw 12, a first fixing ring 10 and a second fixing ring 11 are respectively threadedly sleeved on the outer walls of the first fixing screw 12 and the second fixing screw 13, a ratchet 14 is installed on the outer wall of the winding shaft 3, a ratchet 15 is engaged on the ratchet 14, the traction frame is fixed to the bed by a fixing rope 17, and then the injured lower limb of the patient is passed through the traction frame 9, and the knob 20 is turned. The rotation of the knob 20 will drive the second fixing screw 13 to rotate, and the rotation of the second fixing screw 13 will drive the first fixing screw 12 to rotate, and the first fixing screw 12 and The rotation of the second fixing screw 13 will drive the first fixing ring 10 and the second fixing ring 11 to move on the outer walls of the first fixing screw 12 and the second fixing screw 13 respectively and approach each other to clamp and fix the patient's lower limbs. The soft cushion 21 is in direct contact with the patient's lower limbs, which can improve the patient's comfort. Then, the crank 19 is shaken clockwise, and the crank 19 is shaken to drive the winding shaft 3 to rotate. The rotation of the winding shaft 3 drives the winding wheel 4 to rotate. The rotation of the winding wheel 4 will reel in the traction belt 5. The reeling of the traction belt 5 will lift the patient's lower limbs, thereby traction of the patient's lower limbs, so that the patient's The lower limbs are kept in an upright state to avoid the aggravation of trauma caused by lower limb activities and affect the recovery of the lower limbs. There is no need to wrap a bandage or fix it with tape, so the comfort is good. On the other hand, the clockwise rotation of the ratchet 14 is not affected by the pawl 15. When the patient's lower limbs are lifted, the pawl 15 is engaged on the ratchet 14 to lock the height. When the patient's lower limbs are in the same posture for a long time and fatigue occurs, the crank 19 is grasped and fixed in advance, and then the pawl 15 is opened. The reel 3 can be rotated counterclockwise to properly unwind the traction belt 5, adjust the traction height of the lower limbs, and relieve the fatigue of the lower limbs.
[0022] Example 2: Reference Figure 1 , Figure 3 , Figure 4A fixing rope 17 is installed on the L-shaped plate 1, and the material of the fixing rope 17 is high-strength nylon material. Two first limiting rings 18 are installed on the outer wall of the winding shaft 3. There are two first traction frames 2, and the two first limiting rings 18 are respectively distributed on one side of the two first traction frames 2. A crank 19 is installed at one end of the winding shaft 3, and a knob 20 is installed at one end of the second fixed screw 13. The traction frame can be fixed to the bed by the fixing rope 17. The nylon material has strong toughness and meets the use requirements of the fixing rope 17. Through the setting of the two first limiting rings 18, the activity of the winding shaft 3 can be restricted, so that the winding shaft 3 can only rotate in the first traction frame 2, and cannot move back and forth on the first traction frame 2, thereby improving the stability of the winding shaft 3. Through the crank 19 and the knob 20, shaking the crank 19 is convenient for driving the winding shaft 3 to rotate, and rotating 30 is convenient for driving the second fixed screw 13 to rotate.
[0023] Reference Figure 4 In order to improve the comfort of contact, the inner walls of the first fixing ring 10 and the second fixing ring 11 are both installed with cushions 21, and the material of the cushions 21 is rubber. The cushions 21 directly contact with the patient's lower limbs, which can improve the comfort of the patient.
[0024] Reference Figure 4 In order to limit the movement of the first fixed screw 12 and the second fixed screw 13, the outer walls of the first fixed screw 12 and the second fixed screw 13 are installed with second limiting rings 22, and the two second limiting rings 22 are respectively distributed on both sides of the traction frame 9. Through the setting of the second limiting rings 22, the first fixed screw 12 and the second fixed screw 13 can be prevented from moving back and forth in the traction frame 9, so that the first fixed screw 12 and the second fixed screw 13 can only rotate in the traction frame 9.
[0025] Reference Figure 4 In order to facilitate support, a support block 23 is installed in the traction frame 9, and a support plate 24 is installed on the support block 23. When the patient's lower limbs pass through the traction frame 9, the patient's lower limbs can be supported by the support plate 24, which is convenient for the next step of fixation.
[0026] Working principle of the utility model: when in use, first fix the traction frame on the bed through the fixing rope 17, then pass the injured lower limb of the patient through the traction frame 9, turn the knob 20, the rotation of the knob 20 will drive the second fixing screw 13 to rotate, the rotation of the second fixing screw 13 will drive the first fixing screw 12 to rotate, the rotation of the first fixing screw 12 and the second fixing screw 13 will drive the first fixing ring 10 and the second fixing ring 11 to move on the outer walls of the first fixing screw 12 and the second fixing screw 13 respectively and approach each other to clamp and fix the patient's lower limb, the soft cushion 21 directly contacts the patient's lower limb, which can improve the patient's comfort, and then shake the crank 19 clockwise, the crank 19 will drive the winding shaft 3 to rotate, the rotation of the winding shaft 3 will drive the winding wheel 4 to rotate, the winding wheel 4 rotates The traction belt 5 will be rolled up, and the traction belt 5 will be rolled up to lift the patient's lower limbs, thereby traction of the patient's lower limbs, so that the patient's lower limbs can be kept in an upright state, and the lower limb activities can be prevented from causing aggravation of trauma and affecting the recovery of the lower limbs. There is no need to wrap a bandage and fix it with tape, and the comfort is good. On the other hand, the clockwise rotation of the ratchet 14 is not affected by the pawl 15.
