Automatic adjustment stretching knee joint rehabilitation training device

Abstract

The invention discloses an automatic adjustment stretching knee joint rehabilitation training device. The device comprises a fixed seat, and a seat integrally formed with the fixed base is arranged onthe side face of the fixed base. The thickness of the seat is smaller than that of the fixed seat; two groups of bending trainers are arranged on the fixed seat, two groups of mounting grooves are formed in the fixed seat, each group of mounting grooves comprises a front mounting groove and a rear mounting groove, each bending trainer comprises a shank fitting rod, and thigh fitting rods rotationally connected with the shank fitting rod are arranged on two sides of the upper end of the shank fitting rod. When the device is in use, if a patient cannot bend autonomously, the operation can be performed by automatically stretching an adjusting rod, a connection driving plate is driven to move, therefore, the bending effect of the bending trainers can be adjusted autonomously, rehabilitation training work of the knee joint can be completed autonomously without cooperation of other people, adaptive training can be conducted according to different recovery requirements of individuals, a conventional fixed adjustment or non-adjustment mode is avoided, and the use requirements of different patients are met.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a self-adjusting and stretching knee joint rehabilitation training device. Background technique [0002] The structure of the knee joint is the most complicated trochlear joint among the joints in the whole body, especially in the extension and flexion activities, the joint bears a huge leverage force, because the knee joint bears most of the weight from the human body, due to its large range of motion, its structure makes They bear greater impact and pressure than the hip and ankle joints. They are the fastest-wearing part of the human body and the earliest aging part. The knee joint is one of the joints that are most prone to stiffness after trauma. [0003] In the later stage of knee joint injury recovery, in order to ensure the normal interaction of the knee joint in the future, leg bending training is required to ensure the free movement of the knee joint in the later stage.

Problems solved by technology

[0003] In the later stage of knee joint injury recovery, in order to ensure the normal interaction of the knee joint in the future, leg bending training is required to ensure the free movement of the knee joint in the later stage. Chinese patent announcement number CN209933410U is a kind of knee joint rehabilitation device, CN209450876U is a kind of knee joint rehabilitation Training devices are all such devices, but there is a problem with existing such devices, that is, when training, the patient needs to bend himself through the strength of the legs, but the recovery of the patient is different, and often requires It can only be used with the help of others, and the adjustment method is too inflexible, mainly relying on the return method of the spring, which further reduces the adaptability of this type of device when used
