A multi-degree-of-freedom hip support and detection device

Abstract

The invention discloses a multi-degree-of-freedom hip supporting and detecting device applied to a lower limb rehabilitation robot. The multi-degree-of-freedom hip supporting and detecting device comprises a mounting pedestal, an X-direction moving mechanism, a Y-direction moving mechanism, a Z-direction rotating mechanism and a sensor detection module. The mounting pedestal comprises a top connection board, a middle connection board and a bottom connection board connected with a robot body; the middle connection board can move in the X direction through the X-direction moving mechanism; the top connection board can move in the Y direction through the Y-direction moving mechanism; the Z-direction rotating mechanism can move in a rotary manner relative to the top connection board, and is provided with a hip connecting position; and the sensor detection module comprises two linear displacement detection units which respectively detect the X-direction moving displacement and the Y-direction moving displacement and an angular displacement detection unit used for detecting the Z-direction rotating angular displacement. The multi-degree-of-freedom hip supporting and detecting device has multiple degrees of freedom, constraints to the patient's limbs are released, the scientificity and comfort level of the rehabilitation training are improved, and the moving state of the patient's hip joint can be detected in real time.

Description

technical field [0001] The invention relates to the technical fields of medical rehabilitation equipment and robots, in particular to a multi-degree-of-freedom hip support and detection device. Background technique [0002] There are more than 10 million stroke patients in my country, and more than 2.5 million new patients are diagnosed each year. Among these patients, 70% to 80% of patients will have different degrees of lower limb movement disorders. Medical research shows that this kind of motor dysfunction caused by nerve injury can be treated through timely rehabilitation training. In the process of traditional rehabilitation exercise training, patients usually need to be assisted by the therapist to perform individual or comprehensive exercise training, which has high work intensity and low efficiency, and cannot monitor the patient's therapeutic effect. Therefore, it is necessary to develop a lower limb rehabilitation robot to assist Doctors conduct rehabilitation t...

Problems solved by technology

However, the importance of balance training in a free state to the rehabilitation of hemiplegic patients is ignored. During the training process, patients are greatly restrained and cannot move their bodies freely, which affects the rehabilitation process and rehabilitation effect; The monitoring and observation of the hip movement state will greatly affect the real effect of rehabilitation training
