Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a special positioning instrument for orthopedic joints. Background Art

[0002] After adulthood, the ability of human joints to repair themselves decreases significantly. Therefore, when joints are damaged by disease or external forces, bone and joint degeneration occurs, resulting in joint lesions, which are mostly seen in middle-aged and elderly people. They are related to factors such as age, obesity, strain and genetics. With the accumulation and destruction of multiple unfavorable factors, joint cartilage degeneration and exfoliation, bone sclerosis or cystic changes, bone hyperplasia at the joint margins, synovial inflammatory reactions, joint deformities, etc. Clinically, joint pain, swelling, deformity and limited mobility occur.

[0003] Most existing technologies for bone and joint fixation are difficult to adjust the angle arbitrarily, and rigid fixation such as plaster and leggings will cause excessive compression of the leg muscles, which may cause local damage due to hard friction, thereby causing secondary damage, which is extremely detrimental to the recovery of the patient's joints. Therefore, in view of the above situation, there is an urgent need to develop a special orthopedic joint locator to overcome the shortcomings in current practical applications. Utility Model Content

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A special positioning instrument for orthopedic joints, comprising:

[0007] A first support tube and a second support tube, wherein the first support tube and the second support tube are respectively placed on the outside of the patient's thigh and calf;

[0008] A clamping assembly, which is arranged inside the first supporting tube and the second supporting tube, and is used to fix the thigh and calf of the patient;

[0009] A rotating mechanism, the rotating mechanism is arranged between the first supporting cylinder and the second supporting cylinder;

[0010] Wherein, the rotating mechanism comprises:

[0011] A connecting assembly, which is arranged between the first supporting tube and the second supporting tube and is used to realize the connection between the first supporting tube and the second supporting tube;

[0013] A positioning component is arranged between the connecting component and the adjusting component, and is used to cooperate with the adjusting component to fix the connecting component.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] When the device is in operation, the first support tube is sleeved on the outer side of the thigh, and the outer side of the second support tube is sleeved on the outer side of the calf. The connecting component can realize the connection between the first support tube and the second support tube, and the adjusting component can drive the second support tube to rotate, and can adjust the angle between the first support tube and the second support tube. The adjusting component can also drive the positioning component, and the positioning component can fix the connecting component. The first support tube and the second support tube can remain stable after adjustment. Compared with the prior art, it is difficult to arbitrarily adjust the angle of bone joint fixation, and the rigid fixation such as plaster and leggings will cause excessive compression of the leg muscles, which may cause local damage due to hard friction, thereby causing secondary damage, which is extremely unfavorable to the recovery of the patient's joints.
