Postoperative rehabilitation device for total knee replacement

Abstract

The invention discloses a postoperative rehabilitation device for total knee replacement. The postoperative rehabilitation device comprises an equipment shell, a reversal mechanism, a first pedal piece, a second pedal piece and a reciprocating driving mechanism, wherein the reversal mechanism is arranged in the equipment shell and is provided with a first driving end and a second driving end; the rotation directions of the first driving end and the second driving end are opposite; the first pedal piece and the second pedal piece are respectively located on two sides of the equipment shell and are both connected to the reversal mechanism; and the reciprocating driving mechanism is connected with the reversal mechanism and is used for driving the reversal mechanism to rotate in a reciprocating mode, so that the first pedal piece and the second pedal piece can be driven by the reversal mechanism to rotate in different directions and execute alternately. According to the postoperative rehabilitation device, which is provided by the embodiment of the invention, for the total knee replacement, the knee joint bending and stretching action of a patient can be achieved, knee bending and stretching training is sufficient, a knee joint rehabilitation training effect is better, and in addition, the rehabilitation device has a small size and a simple structure and is suitable for being used on a sickbed for training.

Description

technical field [0001] The invention relates to rehabilitation training equipment, in particular to a rehabilitation device after total knee replacement. Background technique [0002] Total knee arthroplasty (TKA) can effectively relieve pain, improve mobility, and correct deformity. It is an effective solution to a variety of end-stage knee diseases, and it is also a common major orthopedic surgery for elderly patients. With the development of population aging, the demand for patients and operations increases, and special attention should be paid to the particularity of perioperative treatment of middle-aged and elderly bodies. The decline of body functions in the elderly, weakened lower limb function and muscle strength, and decreased ability to resist stress can all lead to Postoperative recovery delay. The enhanced recovery after surgery (ERAS) model was first proposed by the Danish physician Kehlet: effective perioperative management measures are used to reduce traumat...

AI Technical Summary

Problems solved by technology

According to clinical experience, the CPM equipment of the related technology does not provide enough training for knee flexion and knee extension, resulting in the lack of straightening and buckling of some affected knees. In addition, it is large in size and complex in structure, and it is inconvenient to use on the hospital bed.
