Product Design Specification for BME 200 300 group 28E Prosthetic Finger Device October 15 2007 Group members Dustin Gardner Karen Chen Richard Bamberg Allison McArton Alex Kracht Function The focus of this project is to design a substructure and connecting mechanism for an implant retained finger prosthetic Currently the only method used in the United States is a slip cover which holds the prosthetic onto the remaining portion of an amputated finger New approaches have been used in other countries which involve implanting an object through the distal end of a partial digit bone The object is such that a prosthetic finger with a solid substructure can be attached in order to achieve increased motility and use of the prosthetic finger without having any parts fall off Our team is to design a prosthetic finger substructure and connection apparatus which will successfully match these characteristics Client Requirements Either new or improved attachment system from current system Either new or improved prosthetic substructure from current system Computer simulation of final design Interested in experimental work with hand surgeon Budget of 500 Design Requirements According to the client the implant retained finger prosthesis must hold firmly to the terminal amputated portion of the finger This could be done either through a sleeve concept or through osseo integration The prosthesis should also be easy enough to remove such that maintenance and hygiene may continue unimpeded and unobstructed However the implant must not detach too easily when certain external forces and shear forces are applied to the finger prosthesis As such the finger prosthesis must also maintain an element of support functionality and fulfill the aesthetic requirement of resembling a real finger in appearance function and attachment Our client wants the group to devise a new attachment system or build upon the existing system in conjunction with a simulator model The simulator model is necessary to
