A kind of metacarpophalangeal joint stiffness stretching device

Abstract

The invention relates to a metacarpophalangeal joint stiffness drafting device. The problem that an existing support cannot effectively control the direction of force, and consequently treatment needs cannot be met is mainly solved. The device comprises a palmaris supporting clamping plate, a binding part, a finger traction assembly and a tension guide part, the finger traction assembly comprises a finger sleeve, a traction line and a clamping part, the tension guide part is an adjusting plate, the adjusting plate is fixed to the palmaris supporting clamping plate and extends downwards, guide holes sequentially distributed in the extending direction of the adjusting plate are formed in the adjusting plate, and one guide hole corresponds to one force direction. The finger sleeve is used for being arranged on the finger in a sleeving mode, one end of the traction line is connected with the finger sleeve, the other end of the traction line penetrates through the corresponding guide hole to be connected with the clamping part, and the clamping part is fixed to the adjusting plate in a clamped mode. According to the metacarpophalangeal joint stiffness drafting device, the direction of force can be effectively controlled to meet treatment needs, the direction of drafting force of all metacarpophalangeal joints is perpendicular to the proximal phalanx and points to the navicular bone, the aim of treatment is effectively achieved, and the advantages of being simple in manufacturing process, low in treatment cost and good in treatment effect are achieved.

Description

technical field [0001] The invention relates to a brace, in particular to a stretching device for metacarpophalangeal joint stiffness. Background technique [0002] Hands are the most commonly used organs in our daily life and work. In most cases, the hands are not well protected, and at the same time need to be in constant contact with various tools and objects. When a fall or impact occurs, the hands will be damaged. Reflexive support and palm support also make it the most vulnerable part of the body. How to correctly deal with hand trauma so that it can recover faster and more completely in function and appearance has become a common concern of patients and doctors. Hand joint stiffness is a common complication after hand trauma, which seriously affects the recovery of hand function. The purpose of rehabilitation is to help the injured hand regain good function. [0003] At present, the comprehensive rehabilitation treatment methods for hand joint stiffness include wax...
