A new concept for the hardening of polymers allowing the production of disposable surgical blades preventing the need for sterilisation (DISBLADE)

Objective

The economic objective of our work is to enable the partners and the estimated 10 licences to Displace at least 0.1 % of the ?9.8 billion per annum of imported medical technology and devices. Substitute into at least 0.20/% of the European market of ?39 billion p.a. for existing medical technology and devices and 0.04% by 2012. Provide at least ?6.324 million p.a. of automated, disposable surgical blade manufacturing cells. The technological objective of our work is to produce a process for the manufacture of disposable polymer surgical blades that achieves a polymer blade with a surface hardness of at least 7 Mohs'. Achi,eves a blade surface hardness of at least 5 Mohs' to a depth of at least 15 microns. Achieves blade stiffness comparable to existing stainless steel blades Has the ability to produce a blade that can be cost effectively sharpened to a level of sharpness comparable to existing stainless steel blades and conform to the relevant sections in BS 2982:1992, Achieves a hot plate disposal route that renders the blade sharp safe in less than 1 second. A polymer scalpel will be designed using finite element analysis (FEA) to model the blade stiffness and rapid prototyping techniques to verify """"feel"""" and ergonomics. A prototype two shot injection moulding tool with an innovative injection compression feature on the blade cavity to ensure sharpness will be designed and manufactured. The resultant polymer blades will be surface hardened using ScCOz to plasticize the outer layers of the polymer and innovative Sol-Gel chemistry will be used to increase surface hardness. The resultant blades will be tested for blade hardness and stiffness. A grinding and polishing system will be developed to obtain a blade sharpness comparable to existing stainless steel blades. The resultant blades will be tested for sharpness and blade durability. The resultant scalpel handles will be tested for stiffness and """"feel"""". A sharp safe blade disposal system will be created consist
