Joint dysfunction fine adjustment type static drawing support

Abstract

The invention belongs to the technical field of joint dysfunction therapeutic devices, and particularly relates to a joint dysfunction fine adjustment type static drawing support. The joint dysfunction fine adjustment type static drawing support comprises a lower limb surrounding sleeve and an upper limb surrounding sleeve, wherein a lower joint bracket and an upper joint bracket are respectively arranged on the lower limb surrounding sleeve and the upper limb surrounding sleeve and are movably connected through a joint shaft to form a bendable joint assembly; a plurality of buckling band rings are respectively arranged on the lower joint bracket and the upper joint bracket; a plurality of deep slot pulleys are fixed arranged on the lower limb surrounding sleeve and the upper limb surrounding sleeve and are connected through traction ropes to form a pulley group; the lower limb surrounding sleeve or the upper limb surrounding sleeve is provided with a stepping type rope winding rotating wheel. The joint dysfunction fine adjustment type static drawing support is simple in structure, low in cost, easy to operate, safe, reliable and good in treating effect.

Description

technical field [0001] The invention belongs to the technical field of devices for treating joint dysfunction, and in particular relates to a fine-tuning static stretching support for joint dysfunction and treatment of joint stiffness and muscle spasm. Background technique [0002] Limb joint stiffness and muscle spasm caused by various reasons (such as trauma, neurological diseases, long-term immobilization, etc.) will seriously affect the recovery of limb function, resulting in a decline in daily life ability, so systematic rehabilitation must be carried out to restore the joint normal function. The existing methods for the treatment of joint stiffness and muscle spasm generally have three categories: manual therapy (called "joint loosening and stretching technology" in the medical field), orthopedic splint treatment, and orthopedic brace treatment. The present invention relates to special orthopedic brace treatment items, so only the background technology of the orthoped...

AI Technical Summary

Problems solved by technology

[0004] There are many types of static braces used for the treatment of joint stiffness, and their common defects or shortcomings are: some of the structural design is complex, the requirements for material stiffness and toughness are high, the manufacturing process is difficult, and the failure rate in use is correspondingly increased. As a result, the cost of appliances and treatment costs are high, such as lever-type adjustable braces, gear-rail arc-adjustable braces

Or part of the design is relatively simple, but the correction range of joint flexion and extension angles is relatively small, and the specificity and adaptability are poor, such as elastic screw rod stretch adjustment

The above defects or deficiencies affect the treatment progress and effect to a certain extent

In addition, the existing static braces still have the hidden danger of re-injury of the sick limb when the patient is subjected to unforeseen external force (such as a slight collision for a healthy person), and there is a risk that the patient can adjust the flexion and extension angle of the brace by himself. Deficiencies that lead to re-injury of the affected limb
