Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a rehabilitation nursing device for ligament rupture. Background Art

[0002] Ligaments are thickened parts of the fibrous joint capsule, but some are separated from the joint capsule. When subjected to violence, they can cause injuries, and mild cases are ligament sprains. They are caused by excessive stretching of the ligaments or partial fiber rupture. They manifest as pain, tenderness, swelling of varying degrees, and limited movement. X-ray examinations show no abnormalities. Severe cases are ligament ruptures, sometimes combined with joint sprains, avulsion fractures, or joint dislocations. They manifest as pain, obvious swelling, congestion, joint effusion or hematoma, and obvious limitation of movement. X-rays show that the joint cavity is uneven in width. Ligament strain can be treated with local immobilization, physical therapy, or closure. Complete rupture of the ligament generally requires surgical treatment, and some fresh closed ruptures can be treated with plaster fixation.

[0003] After a ligament is torn, a ligament tear protector is needed for protection. Traditional knee ligament tear protectors are mostly worn on the patient's thigh and calf to fix the patient's thigh and calf, thereby achieving the purpose of braking the patient's knee joint. However, this type of protector has the following defects when used: Since traditional protectors can only fix the knee joint, when the knee ligament is gradually recovering, the patient needs to properly train the knee joint. Therefore, when the patient wears the device, the knee joint cannot move. After the patient takes off the device, if the patient's knee joint has a large movement angle, it is easy to cause secondary injury to the knee ligament. In response to the above defects: To this end, we propose a ligament tear rehabilitation care device. Utility Model Content

[0025] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a ligament tear rehabilitation nursing device of the present invention in conjunction with the accompanying drawings.

[0026] like Figure 1-3 As shown, a ligament tear rehabilitation nursing device of the utility model comprises a thigh protector 1 and a calf protector 2, an adjustment structure is arranged between the thigh protector 1 and the calf protector 2, the adjustment structure comprises a rotating disk 3, a rotating track groove 4 is arranged on the inner wall of the rotating disk 3, an adjusting rod 5 is rotatably connected to the inner wall of the rotating track groove 4, the lower end of the adjusting rod 5 is fixedly connected to the upper surface of the calf protector 2, and a limiting component which can limit the rotation angle of the adjusting rod 5 is arranged between the adjusting rod 5 and the rotating disk 3, the limiting component comprises a fixed installation The arc sleeve 6 is on the outer annular surface of the rotating disk 3, and the lower surface of the thigh protector 1 is fixedly connected to the outer annular surface of the arc sleeve 6. The inner wall of the arc sleeve 6 is slidably connected with an arc guide rod 7. One end of the arc guide rod 7 is fixedly connected to the surface of the adjusting rod 5. The centers of the arc sleeve 6 and the arc guide rod 7 coincide with the rotation center of the adjusting rod 5. Rotating the adjusting rod 5 can drive the arc guide rod 7 to slide along the inner wall of the arc sleeve 6, and after rotating the adjusting rod 5, rotation will occur between the thigh protector 1 and the calf protector 2.

[0027] The surface of the arc-shaped guide rod 7 is provided with an external thread, and the surface of the external thread is threadedly connected to a limiting cylinder 8. The outer diameter of the limiting cylinder 8 is larger than the inner diameter of the arc-shaped sleeve 6. After the thigh protector 1 and the calf protector 2 are worn on the patient's thigh and calf, the limiting cylinder 8 is rotated to change the distance between the arc-shaped sleeve 6 and the limiting cylinder 8. When the patient rotates his calf, the arc-shaped guide rod 7 will slide on the inner wall of the arc-shaped sleeve 6. When the limiting cylinder 8 contacts the arc-shaped sleeve 6, the limiting cylinder 8 will limit the arc-shaped guide rod 7 from continuing to enter the arc-shaped sleeve 6, thereby limiting the rotation angle of the patient's calf.

[0028] Compared with the prior art, the device utilizes the change of the spacing between the limit cylinder 8 and the arc sleeve 6 to adjust the rotation angle of the adjustment rod 5. When the patient needs to properly train the knee joint, the limit assembly is used to adjust the rotation angle of the adjustment rod 5, thereby avoiding the problem of excessive rotation of the knee joint leading to knee ligament strain.

[0029] A training component for training the patient's knee joint ligaments is arranged inside the arc sleeve 6, and the training component includes a compression spring 9 slidably connected to the inner wall of the arc sleeve 6, an internal thread is provided at one end of the arc sleeve 6 away from the arc guide rod 7, and a blocking cap 10 is threadedly connected to the inner wall of the internal thread, and a baffle 11 is fixedly installed at one end of the arc guide rod 7 away from the adjusting rod 5, and the surface of the baffle 11 is slidably connected to the inner wall of the arc sleeve 6.

[0030] After the compression spring 9 is placed into the arc sleeve 6, the blocking cap 10 is then screwed into the arc sleeve 6. At this time, one end of the compression spring 9 contacts the blocking cap 10, and the other end of the compression spring 9 contacts the baffle 11. When the patient rotates the knee joint, the arc guide rod 7 will slide along the inner wall of the arc sleeve 6, and the baffle 11 will move synchronously to drive the compression spring 9 to contract, so that the patient can overcome the contraction force of the compression spring 9 to achieve the training of the patient's knee joint ligaments.

[0031] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention.
