[0032] A guided traction frame is an orthopedic surgical instrument, and its main function is to fix and traction the patient's limbs. Existing guided traction frames mostly have adjustment functions. The traction frame used to fix the legs can fix the patient's legs at a certain angle according to the surgical requirements and the patient's body shape. However, some patients need to be fixed for a long time after surgery to ensure a good postoperative effect. Long-term fixation may cause discomfort to the patient and hinder the blood circulation in the patient's legs, which may have an adverse effect on the treatment effect.

[0033] In this solution, one end of the bracket 1 is connected to the operating table, and the patient can lie on the operating table. The medical staff can screw the first screw rod 202 to make one end of the first screw rod 202 disengage from the bracket 1, thereby sliding the first mounting sleeve 201 at the outer end of the bracket 1, and roughly adjusting the position of the first mounting sleeve 201 according to the patient's leg shape. After the adjustment is completed, tighten the first screw rod 202, and then rotate the second screw rod 204 to make the second screw rod 204 disengage from the first height limiting rod 205, so that the user can adjust the height of the first height limiting rod 205 and move the fixing plate 211 to the height required for the patient's foot to be fixed. After moving, tighten the second screw rod 204 to fix the first height limiting rod 205, and then use the strap to fix it. The patient's foot is fixed on the fixing plate 211, and the inner side of the patient's knee is supported by the knee support assembly 3, so that the patient's leg is fixed at a certain angle. During the long-term fixation process, in order to reduce the patient's discomfort, the medical staff can start the servo motor 213 to drive the turntable 214 to rotate slowly and uniformly, and drive the connecting rod 215 to move through the turntable 214, thereby pushing the first limit block 203 to move back and forth periodically at the outer end of the first mounting sleeve 201, thereby driving the patient's foot to perform slow and slight reciprocating motion, thereby preventing the patient's legs from being still for a long time, which can effectively reduce the patient's discomfort and promote blood circulation in the patient's legs without affecting the fixation effect of the patient's legs.

[0034] See also Figure 2-3 The top end of the first height limiting rod 205 is threadedly connected to the third screw rod 206, one end of the third screw rod 206 passes through the first height limiting rod 205 and abuts against the limiting tube 207, the inner end of the limiting tube 207 is rotatably connected to the screw rod 208, one end of the screw rod 208 extends to the outer end of the limiting tube 207 and is fixedly connected to a handle, a hollow connecting column 209 is sleeved on the outer end of the screw rod 208, and one end of the hollow connecting column 209 is fixedly connected to a screw sleeve 210 matching the screw rod 208.

[0035] After the medical staff fixes the patient's foot, the third screw rod 206 can be rotated to disengage the third screw rod 206 from the position limiting tube 207. Then the position limiting tube 207 can be pushed to be fixed on the top of the first height limiting rod 205, so as to further adjust the position of the patient's foot. After the adjustment, the third screw rod 206 can be tightened. In the process of fixing the patient's leg, it is occasionally necessary to slightly adjust the position of the patient's foot or the bending angle of the leg. If the position limiting tube 207 or the first installation sleeve 201 is slidable, it is more troublesome and difficult to control the degree of movement. At this time, the medical staff can turn the handle to drive the screw rod 208 to rotate inside the position limiting tube 207, and the screw sleeve 210 is driven to move at the outer end of the screw rod 208 through the rotation of the screw rod 208, and then the hollow connecting column 209 is pushed to slide at the inner end of the position limiting tube 207 through the screw sleeve 210, and then the fixing plate 211 is driven to move, so as to make a slight adjustment to the position of the patient's foot.

[0036] See also Figure 5 The knee support assembly 3 includes a second mounting sleeve 301, which is sleeved on the outer end of the bracket 1, and the outer end of the second mounting sleeve 301 is threadedly connected to a fourth screw 302, one end of the fourth screw 302 passes through the second mounting sleeve 301 and abuts against the bracket 1, the outer end of the second mounting sleeve 301 is fixedly connected to a second limit block 303, the second limit block 303 is slidably connected to a second height limiting rod 305, and the outer end of the second limit block 303 is threadedly connected to a fifth screw 304, One end of the fifth screw rod 304 passes through the second limit block 303 and abuts against the second height limiting rod 305. A mounting frame 306 is provided on the upper side of the second height limiting rod 305. The inner end of the mounting frame 306 is rotatably connected to the supporting roller 307, and the bottom end of the mounting frame 306 is fixedly connected to a pair of sliding rods 308. The sliding rods 308 are slidably connected to the second height limiting rod 305, and a spring 309 is sleeved on the outer end of the sliding rod 308. The two ends of the spring 309 are respectively fixedly connected to the second height limiting rod 305 and the mounting frame 306.

[0037] During the process of fixing the leg guard, the patient's leg is bent, and the inner side of the patient's knee is in a suspended state. It is necessary to support the inner side of the patient's knee to enhance the fixation effect. In this solution, the medical staff can rotate the fourth screw rod 302 to disengage the fourth screw rod 302 from the bracket 1, then slide the second installation sleeve 301 to the lower end of the inner side of the patient's knee, and tighten the fourth screw rod 302, and then rotate the fifth screw rod 304 to disengage the fifth screw rod 304 from the second height limiting rod 305, so that the medical staff can slide the second height limiting rod 305 up and down to adjust the height of the support roller 307, so that the support roller 307 comes to the position of the patient's knee, and then tighten the fifth screw rod 304 to fix the second height limiting rod 305, and then the medical staff can press the support roller 307 downward to install The frame 306 drives a pair of slide bars 308 to move downward and squeezes the spring 309, then moves the inner side of the patient's knee to the upper end of the support roller 307, releases the support roller 307, and causes the support roller 307 to abut against the inner side of the patient's knee through the elastic action of the spring 309, thereby supporting the inner side of the patient's knee. The support roller 307 is rotatably connected to the mounting frame 306 and can rotate following the slight movement of the patient's legs. The outer end of the spring 309 is wrapped with a cushion to improve the patient's comfort. When the patient's foot moves back and forth following the movement of the first limit block 203, the patient's knee will also rise and fall slightly. At this time, the setting of multiple springs 309 can ensure that the support roller 307 is always in contact with the inner side of the patient's knee, thereby ensuring the support and fixation effect.

[0038] Working principle:

[0039] When in use, the patient needs to lie on the operating table, and the medical staff screws the first screw rod 202 to make one end of the first screw rod 202 detach from the bracket 1, so as to slide the first installation sleeve 201 on the outer end of the bracket 1, and roughly adjust the position of the first installation sleeve 201 according to the patient's leg shape. After the adjustment is completed, tighten the first screw rod 202, and then rotate the second screw rod 204 to make the second screw rod 204 detach from the first height limiting rod 205, so that the user can adjust the height of the first height limiting rod 205 and move the fixing plate 211. The first height-limiting rod 205 is fixed to the desired height of the patient's foot, and the second screw rod 204 is tightened to fix the first height-limiting rod 205 after the movement is completed. Then, the patient's foot is fixed to the fixing plate 211 by a strap. Then, the medical staff rotates the fourth screw rod 302 to separate the fourth screw rod 302 from the bracket 1, and then slides the second mounting sleeve 301 to the lower end of the inner side of the patient's knee, and tightens the fourth screw rod 302. Then, the fifth screw rod 304 is rotated to separate the fifth screw rod 304 from the second height-limiting rod 305, so that the medical staff can slide the second height-limiting rod 305 up and down to fix the patient's foot. The height of the support roller 307 is adjusted to make the support roller 307 reach the position of the patient's knee, and then the fifth screw rod 304 is tightened to fix the second height-limiting rod 305. Then the medical staff can press the support roller 307 downward to make the mounting frame 306 drive the pair of sliding rods 308 to move downward and squeeze the spring 309. Then the inner side of the patient's knee is moved to the upper end of the support roller 307, and the support roller 307 is released. The elastic action of the spring 309 makes the support roller 307 contact with the inner side of the patient's knee, thereby The inner side of the patient's knee is supported. During the long-term fixation process, in order to relieve the patient's discomfort, the medical staff can start the servo motor 213 to drive the turntable 214 to rotate slowly and evenly, and the turntable 214 drives the connecting rod 215 to move, thereby pushing the first limit block 203 to move back and forth periodically at the outer end of the first mounting sleeve 201, thereby driving the patient's foot to perform slow and slight reciprocating motion, thereby preventing the patient's legs from being stationary for a long time, which can effectively relieve the patient's discomfort and promote blood circulation in the patient's legs.

[0040] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
