Multiple-pose lower limb rehabilitation training robot

Abstract

The invention discloses a multiple-pose lower limb rehabilitation training robot which comprises a robot base and a training bed. The training bed comprises two leg mechanisms, a seat, a seat width adjusting mechanism, a human body gravity center adjusting mechanism, a back cushion, a weight reduction system and a seat back cushion angle adjusting mechanism. The robot base comprises a bed body angle adjusting mechanism, and the bed body angle adjusting mechanism is matched with a seat angle adjusting mechanism and can provide multiple pose training modes including lying, sitting, standing and the like for a paralysis patient. Each leg mechanism comprises a hip joint, a knee joint and an ankle joint. The hip joint, the knee joints and the ankle joints are driven by a motor and are provided with angle and force sensors, can be used for recognizing motion intention of the patient and facilitate active and aiding training of the patient. The human body gravity center adjusting mechanism, the leg mechanisms and the weight reduction system are mutually matched, bionic gaits approximating to natural walking of a human body can be achieved, and gait training effect can be improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a multi-position lower limb rehabilitation training robot. Background technique [0002] At present, the number of patients with lower limb paralysis caused by stroke, spinal cord injury and traumatic brain injury is very large, showing an upward trend. Patients with lower extremity paralysis often need long-term rehabilitation after symptomatic treatment in the acute phase to restore the motor function of the lower limbs. Exercise therapy is a common method of lower extremity rehabilitation. Traditional rehabilitation training involves the therapist manually driving the patient's lower limbs to perform exercise training, which is highly subjective, time-consuming and laborious, and the effect is not ideal. As an automated, precise, and intelligent medical device, rehabilitation robots have strong advantages in providing continuous and quantitative rehabilitation traini...

Problems solved by technology

[0004] However, most of the existing rehabilitation robot systems design a specific training trajectory for a training posture, which is difficult to meet the training needs of paralyzed patients at different stages of rehabilitation; it is difficult to optimize the prescription of rehabilitation training based on the same platform and the same standard. get the best recovery
