Novel elbow joint functional rehabilitation device

Abstract

The invention relates to the field of an assistant medical treatment apparatus, and aims to provide a novel elbow joint functional rehabilitation device with good rehabilitation effect. The technical plan applied is: a novel elbow joint functional rehabilitation device comprises a base, wherein a big arm fixing plate and a small arm fixing plate are arranged on the base. Back faces of the small arm fixing plate and the big arm fixing plate are provided with connecting ears, and hinged with the base through a hinging shaft at the connecting ear. The back face of the end part of the small arm fixing plate closing to a gap is further provided with a first connecting plate. A driving mechanism is arranged on the base and comprises a linear motor and a flexible connecting component; the flexible connecting component comprises a spiral spring and a short rod; one end of the short rod is hinged to the output end of the linear motor, and the other end thereof is fixedly connected to one end of the spiral spring; the other end of the spiral spring is fixedly connected with the first connecting plate. The novel elbow joint functional rehabilitation device is more adaptive to the rehabilitation demand in the early period of rehabilitation, and can avoid damage of the elbow joint and greatly improve the rehabilitation effect.

Description

technical field [0001] The invention relates to the field of auxiliary medical devices, in particular to a novel elbow joint function rehabilitation device. Background technique [0002] The elbow joint is an important functional joint of the upper limb. Elbow joint or upper extremity surgery, such as orthopedic cross-joint surgery or neurosurgery peripheral nerve repair surgery, requires external fixation of the elbow joint after the operation, but after the fixation is completed, the elbow is often left unable to bend, stretch or flexibly. Sequelae of bent-angle foot. At present, the conventional method for this sequela is to achieve the purpose of gradual rehabilitation by artificially assisting and repeating the upper limbs of the patient. This method is time-consuming and labor-intensive, and the labor intensity is too high for the nursing staff. For this reason, there have been auxiliary devices aimed at the recovery of elbow joint function in the prior art. At prese...

Problems solved by technology

[0003] However, there are still many defects in this type of device. For example, in the existing rehabilitation aids, since the big arm plate is fixed and the driving force for driving the forearm plate is too mechanized, the forearm plate is rigid during bending. Too large, easy to cause damage to the elbow joint

Especially for patients in the early stage of rehabilitation, the amount of bending of the elbow joint should not be too large, and the forearm plate of the existing rehabilitation aid device lacks a bending buffer during the bending process (the forearm plate bends as much as the motor rotates), resulting in Not applicable in the early stages of recovery
