Single Use External Fixator for the Hand - FEM

Fixation device for fractures of the upper limb (humerus, radius and ulna) single-use, lightweight, cheap and easy to use.

Description

lightweight, cheap and easy to use.
Description: The high cost of fixators has led to that reuse is established as the common guideline in the hospital sector, causing quality management problems of the immobilised material. On the one hand, it is necessary to control and follow up of the implanted materials in the patients, which is often not returned, with the consequent economic losses. On the other hand, it generates problems associated with the quality control of the device which, apart from its first implantation, is always second hand.
For these reasons, we have developed a fixation device for fractures of the upper limb (humerus, radius and ulna) that breaks the traditional concept of external fixation devices and reusable expensive to introduce a new single-use device, inexpensive and easy to use.
The design combines different materials, as a last generation thermoplastics (parts with complicated geometries THAT working under distributed strains or deformations), and stainless steel (components with simple geometry working under concentrated stress due to tightening).
The achievement of an optimum design has involved several cycles of design, mechanical simulation by finite elements, manufacture and mechanical tests.

Potential Benefits and Uses

The main advantage of the FEM in comparison with other fixing devices on the market is that its low cost makes it possible to use it for a single patient, and it is perfectly adapted to the new guidelines of budgetary management in the agreements between insurance companies and private clinics. It is preassembled in a sterile blister pack with the needed instrumental. The FEM is a very lightweight fixator, which presents a simple blocking mechanism which simplifies implantation.
The FEM is a single-use device, with a helpful and very economic design, which requires a surgically simple technique (easy implantation) and combines a low weight and great stiffness.
