The concept of preparation of oesophageal prosthesis based on long-fibre composite materiał

Purpose: In the work, there was investigated the possibility of an application of long-fibrous composite material as a based material for prototype of oesophageal prosthesis (tubular element) with the use of so called arms, using coiling, plaiting and winding techniques. Design/methodology/approach: Coiling, plaiting and winding techniques were used. As a reinforcement, aramid fibres bound with different types of so called silicone rubbers. Selection of winding parameters has been made in order to fabrication of prosthesis with appropriate mechanical parameters. Findings: Technological tests have given promising results. In the summary, comments and technological remarks are described. For prototype of prosthesis manufacturing, components, which in the form of composite materials are characterized by biocompatibility, have been used, that is medical silicone and aramid fibres. Research limitations/implications: The pilot investigation of fabricated prototypes of internal oesophageal prosthesis show that it is necessary to change the fabrication technology onto dry winding followed by closing obtained reinforcement in a mould and saturation with silicone. The idea is to get better silicone content and connected with it better elasticity and tightness of the prosthesis. Originality/value: Accepted method of winding is the most effective due to fabrication of prototypes of internal oesophageal prosthesis in laboratory. In industry, probably the better method will be plaiting, e.g.: as in the case of high-pressure hose of applied hydraulics.
