Structure of eyelet installation hole in orthopedic appliance of low temperature thermoplastic plate

Abstract

The invention discloses a structure of an eyelet installation hole in an orthopedic appliance of a low temperature thermoplastic plate. The structure comprises an installing hole (2) arranged in an orthopedic appliance body (1), and is characterized in that a hard polymer plate (3) with softening temperature being higher than that of the low temperature thermoplastic plate, is adhered or in heat seal in the middle of the orthopedic appliance body (1) on the periphery of the installing hole (2); an area of the hard polymer plate (3) is slightly larger than an area of a cap of an eyelet; the thickness of the hard polymer plate (3) is 1 / 3-3 / 5 of the thickness of the orthopedic appliance body (1); and the installation hole (2) penetrates through the hard polymer plate (3) and the orthopedic appliance body (1) on the upper part and the lower part of the hard polymer plate (3). According to the orthopedic appliance of the low temperature thermoplastic plate, which adopts the structure, the eyelet installation hole cannot be deformed severely in a moulding stretching process, the eyelet can be prevented from dropping or shaking, and the structure is applicable to industrialized production.

Description

Technical field: [0001] The invention relates to an orthopedic appliance for bone or joint fixation or correction, in particular to an installation hole for fixing fasteners or eyelets for lacing on an orthopedic appliance of a low-temperature thermoplastic plate. Background technique: [0002] Low-temperature thermoplastic plate is a kind of specially synthesized polymer polyester, which is a new type of medical material with memory after a series of physical and chemical treatments. It is widely used in the production of orthopedic external fixators, orthotics (braces), etc. . Among the orthopedic appliances of existing low-temperature thermoplastic plates, some orthopedic appliances suitable for large limbs, such as common waist protectors and thoracolumbar orthotics, usually need to be fixed on the human body with laces and fasteners. The belt needs to be pierced on the base plate of the orthopedic appliance through the eyelet, and the fastener needs to be fixed on the ...

AI Technical Summary

Problems solved by technology

Since the installation of the eye not only requires the staff to have certain professional skills, but also requires some special tools and equipment, otherwise it is difficult to ensure the quality of the installation

Another problem with on-site shaping and installation of eyelets is low work efficiency, because only some simple tools can be carried for on-site installation, not only can’t carry out factory-like flow operations, but also the working conditions are poor

In addition, in order to improve the orthopedic effect of the orthosis, it is necessary to make the orthosis fit well with the limb being orthoped, so there is often a problem that the first-time shaping is not ideal and needs to be reshaped again

In the process of remodeling, there will also be the problem that the hole for installing the eyelet will be enlarged, which will affect the appearance and use effect in the slightest, and make the product scrapped in the worst case.
