Pelvic mechanism for gait rehabilitation with quick adjustment and locking

Abstract

A pelvis mechanism capable of being adjusted and locked fast and used for gait rehabilitation training comprises a base, connecting rods, a connecting box, a horizontal shaft, vertical shafts, swing rods and support arms, wherein the connecting rods are rotatably connected to the base and the connecting box, the rotary shafts of hinges are parallel, the horizontal shaft penetrates the connecting box, the axis of the horizontal shaft is vertical to rotary shafts of the hinges and parallel to the motion trajectory plane where the connecting rod rotates relative to the base, the vertical shafts are connected with the horizontal shaft, the axes of the vertical shafts are vertical to the axis of the horizontal shaft, the swing rods rotate around the vertical shafts, and the support arms are arranged at two ends of the swing rods and swing along with the rotation of the swing rods. The pelvis mechanism has the advantages that the pelvis mechanism can be manually adjusted conveniently and fast without special tools to adapt to pelvises of different widths; the left-right translation, twisting and lateral inclining of a pelvis can be respectively locked independently so as to satisfy the rehabilitation requirements of different patients.

Description

technical field [0001] The invention relates to a rehabilitation medical device, in particular to a pelvic mechanism capable of quick adjustment and locking for gait rehabilitation training. Background technique [0002] In recent years, the aging of the population has intensified, various unhealthy lifestyles, traffic accidents, and work-related injuries have continued to increase. Patients with walking dysfunction caused by stroke, spinal injury, or accidents have become a common group in modern society. In addition to medication and surgical treatment, these patients mainly rely on physical therapy, that is, rehabilitation training. Replacing traditional physical therapists with rehabilitation robots can effectively reduce the workload of physical therapists and improve the recovery efficiency of patients. [0003] The pelvis of the human body is connected with the lumbar spine, and the hip joint is formed with the femur at the bottom. It is a bridge between the spine and...

Problems solved by technology

Most of the existing lower limb rehabilitation robots do not have a pelvic mechanism. Patients are greatly restrained during the training process and cannot move their bodies freely. The importance of balance training for the rehabilitation of hemiplegic patients is ignored, which affects the rehabilitation process.

[0004] The current pelvic mechanism does not have a locking mechanism for each degree of freedom. When the patient is training, each degree of freedom is released and can move freely. However, according to the different rehabilitation stages of the patient, one or several degrees of freedom need to be locked to limit the patient's pelvis. Freedom of movement for better rehabilitation

[0005] The width of the pelvis is different for different patients. During rehabilitation training, the width of the pelvic mechanism needs to be adjusted to suit the body shape of different patients. The current adjustment mechanism mostly relies on screw clamping, and a special tool-wrench is required for operation, which is inconvenient to operate.
