Embodiment Construction

[0052] see Figure 1-7 , a passive knee assist robot, including a thigh fixation group 1, a lower leg fixation group 2, and a knee assist device 3. The thigh fixing group 1 is used for fixing on the thigh. The lower leg fixing group 2 is arranged on the lower side of the thigh fixing group 1 and is used for fixing on the lower leg. The knee joint booster 3 is connected between the thigh fixing group 1 and the calf fixing group 2, and is used for accumulating energy when the calf on the lower leg fixing group 2 and the thigh on the thigh fixing group 1 perform knee-bending movements. The elastic potential energy is stored, and then the elastic potential energy can be used to reset the lower leg on the lower leg fixing group 2 and the thigh on the upper leg fixing group 1 .

[0053] This application includes a thigh fixation group 1, a calf fixation group 2, and a knee joint booster 3, wherein the thigh fixation group 1 is used to fix the thigh, and the calf fixation group 2 is ...

Abstract

The invention relates to the technical field of medical apparatuses and instruments and discloses a passive knee-joint power-assist robot. The passive knee-joint power-assist robot comprises a thigh fixing group, a crus fixing group and a knee-joint power assisting device. The thigh fixing group is used for fixing a thigh, the crus fixing group is used for being fixed to a crus, and by arrangementof the knee-joint power assisting device, energy accumulation in knee bending action of the thigh and the crus can be realized. When the thigh and the crus reset after knee bending, energy accumulated by the knee-joint power assisting device can be converted into kinetic energy to assist the crus on the crus fixing group and the thigh on the thigh fixing group in reset action, and further, the human knee joint can be assisted in stretching to further assist a human body in walking or exercising, so that the knee joint of a user is protected, and the knee joint burden of the user is relieved.The passive knee-joint power-assist robot is suitable for knee protection of healthy people in mountaineering and also applicable to assisted walking of sub-healthy people with knee injuries.

Description

【Technical field】 [0001] The present application relates to the technical field of medical devices, in particular to a passive knee assist robot. 【Background technique】 [0002] As one of the important joints of the lower limbs of the human body, the knee joint needs to bear the weight of the entire trunk, and on the other hand assist the human body to realize walking, running, jumping and other sports. It is unavoidable, and even young people are also affected by knee joint injuries or knee arthritis and other diseases during sports. The emergence of knee joint assisting robots can meet the needs of such patients. Simultaneously, the device can enable the patient to walk normally and relieve the trauma of the patient. [0003] At present, knee joint assisting robots are mostly connected by rigid structures, which are too rigid to replace or assist the human knee joint to play a buffering role in motion, which is not conducive to the recovery of patients. 【Content of inve...
