Technical Field
[0001] The utility model relates to a medical appliance, in particular to a body position pad with adjustable spacing after total hip replacement. Background Art
[0002] With the continuous maturity and popularization of artificial joint replacement technology, more and more patients are undergoing artificial joint replacement surgery in clinical practice. After a successful artificial joint replacement, patients can get out of bed and move around early, which not only significantly improves the quality of life, but also avoids a series of sequelae caused by bed rest.
[0003] The postoperative hip position pad is made of a trapezoidal soft pad. By clamping the position pad between the legs, the hip joint movement is restricted and hip joint rehabilitation is assisted. Reference may be made to the multifunctional postoperative hip position pad disclosed in the existing patent CN214180899U.
[0004] The above technology still has shortcomings: the shape of the positioning pad is fixed, and the distance between the patient's legs cannot be adjusted according to needs, and the effect of assisting hip joint rehabilitation is poor.
[0005] Therefore, how to design a positioning pad that can limit the movement of the hip joint and adjust the distance between the legs has become an urgent problem to be solved in the field of medical devices. Utility Model Content
[0006] The purpose of the utility model is to provide a spacing-adjustable positioning pad after total hip replacement surgery, which separates the patient's legs through a leg separation pad and adjusts the distance between the patient's legs through a spacing adjustment mechanism to limit the movement of the hip joint. At the same time, the affected leg is raised through a lifting pad to reduce the pressure and compression on the leg muscles, thereby assisting the hip joint rehabilitation to a better effect.
[0007] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:
[0008] A postoperative position pad with adjustable spacing after total hip replacement, comprising a leg-lifting pad and a leg-separating pad. The two ends of the leg-lifting pad are respectively a head end and a tail end, the head end of the leg-lifting pad is higher than the tail end, the affected leg is placed on the leg-lifting pad, and the foot of the affected leg is placed on the head end of the leg-lifting pad.
