Description

Adjustable deformed hand orthosis

The invention relates to a shape correction treatment instrument for deformed hands, in particular to deformed hands caused by post-burn scar contracture, which belongs to the technical field of medical devices, in particular to an adjustable deformed hand orthosis.

Background technique

The orthodontic treatment of the claw-shaped hand after burns is complicated and takes a long time, and the deformity is not completely corrected by surgery and is prone to recurrence. While the scar is released by surgery, it is also easy to cause new scar formation; if there is a need for skin grafting, the retraction rate of the skin graft is as high as 30-50%, and the contracture of tendons, joint capsules, ligaments, blood vessels, and nerves is difficult to be safe and effective through surgery release. Aiming at the above problems, some scholars cite the classic bone traction theory and apply bone traction technology to the treatment of burnt claw hands, and have achieved certain results.

At present, there is a lack of mature standardized traction devices in the market. Self-made simple elastic braces are mostly used in clinical treatment, and the deformed parts are corrected with the help of the elastic force of medical Kirschner wires after bending to restore deformation, or the traction force provided by other elastic materials. Although these traction devices can achieve a certain therapeutic effect, they are limited by the personal experience of doctors and should not be widely used. In addition, the treatment period is long, and plastic deformation of the selected elastic material is inevitable, and key parameters are bound to drift, affecting the therapeutic effect; Moreover, the brace construction process is random and goes against the spirit of precision medicine.

Contents of the invention

The present invention aims to solve the problem of lack of mature and standardized deformed hand traction devices in current clinical treatment, and provides an adjustable deformed hand orthosis, which can adjust treatment parameters (such as the magnitude and direction of traction force) at any time during the treatment process. Clinical normative treatment and scientific research provide basic data.

The present invention is realized by adopting the following technical scheme: an adjustable deformed hand orthosis, including several Kirschner wires vertically embedded in the metacarpal bone at one end, and fixed on the arch or semicircle at the other end of each Kirschner wire perpendicular to the back of the hand. Support sheet, one end goes through and is fixed on the support sheet, the other end extends above the finger and is parallel to the hollow support rod on the back of the hand, and the backstop hinge is fixed on the back of the support sheet (the side facing the wrist); it also includes a pull wire, a pull wire One end passes through the hollow support rod and is fixed and wound on the backstop twister, and the other end is connected in series with a tension sensor or a spring balance and is connected with a hook or a fingertip cover. Needle), or directly connected to the fingertip through the fingertip sleeve. When in use, the tension of the stay wire can be adjusted by turning the backstop hinge to realize the adjustment of the fingertip traction force; the tension sensor (through other known display devices connected with the tension sensor configured) or the spring scale can display the traction force, so as to achieve The purpose of accurate quantification of traction force. Wherein the backstop hinge adopts existing known multiple structures.

The hollow support rod is composed of a front hollow fixing rod, a hollow middle adjusting rod and a hollow rear adjusting rod, one end of the front hollow fixing rod passes through and is fixed on the support piece, and one end of the hollow middle adjusting rod is vertical The direction is adjustable to be hinged and fastened to the other end of the hollow fixed rod, and one end of the hollow rear regulating rod is horizontally adjustable to be hinged and fastened to the other end of the hollow middle regulating rod; Direction adjustment, the hollow rear adjustment rod realizes the adjustment of the horizontal direction of the tension. Alternatively, the hollow support rod is composed of a front hollow fixing rod, a hollow middle adjusting rod and a hollow rear adjusting rod, one end of the front hollow fixing rod passes through and is fixed on the supporting sheet, and one end of the hollow middle adjusting rod The horizontal direction is adjustable to be hinged and fastened to the other end of the hollow fixed rod, and one end of the hollow rear adjusting rod is vertically adjustable to be hinged and fastened to the other end of the hollow middle adjusting rod; thus, the hollow middle adjusting rod realizes tension The adjustment in the horizontal direction, the hollow rear adjustment rod realizes the adjustment in the vertical direction of the tension.

Based on the theory of tissue traction, the present invention provides continuous and arbitrarily adjustable traction force to promote the gradual recovery or close to normal shape of the distorted part, so as to achieve the purpose of treatment. The value and direction of the pulling force generated by the invention are stable and adjustable. Compared with similar existing similar products, the structure is stable and controllable, the data is reliable, and it can provide accurate data for follow-up treatment and clinical research.
