Description

Technical Field

[0001] The invention relates to the technical field of traction devices, and in particular to an auxiliary traction device after orthopedic surgery. Background Art

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the skeletal muscle system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. After orthopedic surgery, auxiliary traction devices are generally required to perform stretching and rehabilitation exercises on the patient's limbs, which can easily restore joint function, promote limb swelling, accelerate local blood circulation, and thus promote healing.

[0003] At present, when exercising with the orthopedic postoperative auxiliary traction device on the market, due to the poor health and physical strength of the patients, traction and stretching fatigue and the falling of the counterweight are prone to occur, resulting in strain of the patients.

[0042] After orthopedic surgery, auxiliary traction devices are used to perform stretching and rehabilitation exercises on the patient's limbs, promote the recovery of joint function, reduce limb swelling and accelerate local blood circulation, thereby promoting healing.

[0043] In the related art, an anti-strain mechanism is provided between the No. 1 wire wheel and the No. 2 wire wheel to prevent the patient from being strained due to insufficient traction and stretching force and the falling of the counterweight, thereby ensuring the safety of traction and stretching. However, in actual use, after the counterweight is pulled up, the falling speed is close to the speed of the counterweight falling directly, and the whole process is relatively fast. The method of monitoring only by displacement sensors is prone to misjudgment, and has high requirements on the patient's proficiency. It has certain limitations and requires the use of multiple electrical equipment, which is costly and inconvenient to use.

[0044] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides an orthopedic postoperative auxiliary traction device. When it is needed, it is only necessary to pull the pull ring 29, and pull the counterweight block 21 out of the counterweight box 20 through the rope body 22 to achieve stretching and traction exercises. When the patient becomes weak, it is only necessary to twist the pull ring 29 to rotate the fixed block 26. The ring body 27 limits the fixed block 26 to prevent the counterweight block 21 from falling, thereby protecting the patient. It is more convenient and quick, and improves the convenience of the device.

[0045] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0046] Combination Figure 1-Figure 6 The embodiment of the present application provides an orthopedic postoperative auxiliary traction device, including: a bed 10, one side of which is provided with a counterweight box 20, a counterweight block 21 is slidably connected in the counterweight box 20, a rope body 22 is fixedly connected to the top of the counterweight block 21, a frame 23 is fixedly connected to the top of the counterweight box 20, a rod 1 24 is fixedly connected to the frame 23, a rod 251 is slidably connected in the rod 1 24, a rod 3 252 is slidably connected in the rod 251, and one end of the rod 3 252 is fixedly connected to Spring 253, the other end of the spring 253 is fixedly connected to the rod body 251, the outer side of the rod body 3 252 is fixedly connected to the limiting groove 255, the inner side of the rod body 251 is provided with a limiting block 254, the other end of the frame 23 is fixedly connected to the top of the rod body 251, the outer side of the rod body 251 is fixedly connected with a fixing block 26, the inner side of the rod body 1 24 is fixedly connected with a ring body 27, the bottom of the ring body 27 is provided with a groove body 1 28, and the bottom end of the rod body 3 252 is fixedly connected with a pull ring 29.

[0047] When the patient performs stretching and traction exercises after orthopedic surgery, the patient holds the pull ring 29 and causes the pull ring 29 to pull the rod body three 252, and then causes the rod body three 252 to pull the rod body two 251 to slide downward in the rod body one 24. While sliding, the fixed block 26 passes through multiple ring bodies 27, and the counterweight block 21 is pulled by the rope body 22, so that the counterweight block 21 slides upward from the counterweight box 20. Then, the patient slowly releases the pull ring 29, and the counterweight block 21 slides downward in the counterweight box 20 through the gravity of the counterweight block 21 itself, so as to achieve a single stretching and traction exercise, and then repeats the above steps to achieve multiple traction training. Finally, when the patient is exhausted, he only needs to turn the pull ring 29 to cause the pull ring 29 to drive the rod body three 252 and the rod body one 24 to slide downward. The second body 251 rotates, and at the same time, drives the fixed block 26 to rotate in the rod body 1 24, and then the fixed block 26 is rotated between two adjacent ring bodies 27. When the pull ring 29 is released, the ring body 27 limits the fixed block 26, thereby limiting the height of the counterweight 21 and playing an anti-fall protection effect. On the contrary, when the patient needs to perform low-intensity exercise, the patient pulls the pull ring 29 downward, so that the pull ring 29 pulls the rod body 3 252 to slide out of the rod body 251, and pulls the spring 253. Then, when the pull ring 29 is released, the rod body 3 252 and the pull ring 29 are reset by the rebound force of the spring 253, so that a single training is achieved. Then, the pull ring 29 can be repeatedly pulled to achieve low-intensity training.

[0048] When switching the exercise intensity, first pull the pull ring 29 downward to make the rod body three 252 slide downward from the rod body two 251, and at the same time, make the limit block 254 slide into the limit groove 255, and then rotate the pull ring 29 to make the limit block 254 rotate in the limit groove 255, and the limit groove 255 limits the limit block 254, and then continue to rotate the pull ring 29 to make the rod body three 252 drive the limit block 254 to rotate, and drive the rod body two 251 and the rod body one 24 to rotate, so that the fixed block 26 rotates to the opening on the ring body 27, so that the fixed block 26 can pass through the ring body 27 and slide up and down in the rod body one 24, which is convenient for pulling the counterweight block 21 to slide in the counterweight box 20 through the rope body 22 to perform high-intensity exercise.

[0049] In some embodiments, the second rod body 251 is rotatably connected to a guide wheel 30 , and after one end of the rope body 22 passes around the guide wheel 30 , it is connected to the second rod body 251 , and the guide wheel 30 protects the rope body 22 .

[0050] In some embodiments, a guide plate 271 is fixedly connected to the ring body 27, so that after the fixed block 26 contacts the guide plate 271, the guide plate 271 guides the fixed block 26, making the fixed block 26 slide up and down more stably.

[0051] In some embodiments, the fixing blocks 26 are fixedly connected in plurality, the ring bodies 27 are fixedly connected in plurality, and each of the ring bodies 27 is provided with a plurality of the groove bodies 28, so that the plurality of fixing blocks 26 are in contact with the ring body 27 at the same time, thereby increasing the contact area and improving stability.

[0052] In some embodiments, a box body 40 is fixedly connected to the bottom of the bed body 10, a plug plate 41 is fixedly connected to one side of the counterweight box 20, one end of the plug plate 41 is inserted into the box body 40, a hole body 42 is opened on the plug plate 41, a bolt 43 is threadedly connected to the box body 40, and one end of the bolt 43 is inserted into the hole body 42.

[0053] When disassembly is required, turn the bolt 43 to make one end of the bolt 43 slide out of the hole 42, cancel the fixation of the plug plate 41, and then pull the counterweight box 20 to make the counterweight box 20 drive the plug plate 41 to slide out of the box body 40, thereby realizing the disassembly of the counterweight box 20 and the structure thereon, and vice versa for installation.

[0054] In some embodiments, a second groove 50 is provided at the bottom of the box body 40, and the second groove 50 is in close contact with the counterweight box 20 to play a limiting role.

[0055] In some embodiments, a plurality of bolts 43 are provided, so that the plurality of bolts 43 can be inserted into the plurality of holes 42 at the same time, thereby improving the fixing effect.

[0056] In some embodiments, the number of the holes 42 is greater than the number of the bolts 43. When fixing the plug plate 41, the fixed position of the plug plate 41 in the box body 40 can be changed by inserting the bolts 43 into the holes 42 at different positions, thereby changing the fixed position of the counterweight box 20, and then changing the structure thereon and the position of the pull ring 29, thereby improving practicality.

[0057] In some embodiments, a plurality of support rods are fixedly connected to the bottom of the counterweight box 20, and the support rods support the counterweight box 20 to improve stability.

[0058] In some embodiments, a moving wheel is provided at the bottom of the support rod. When the counterweight box 20 is pushed, the counterweight box 20 drives the support rod and the moving wheel at the bottom of the support rod to move, so that the counterweight box 20 can be easily disassembled.
