“…The judgments given to the alternatives in the PuCC matrix derive from a former discussion among the decision makers, namely the designer, the manufacturer, the surgeon and the business manager of a SME in the northern of Italy, which is specialized in biopsy needles. They provided judgments for each design alternative, depending on the specific function (1,2,3) and criterion that each part of the device must perform. According to the PuCC method, the most suitable combination for the cannula holder geometry seems to be the 1B-2C-3C Fig.…”

“…In the literature, papers related to the design of biopsy needles are mostly aimed at enhancing the biopsy efficiency in relation to the geometry of the cannula and needle. This is for enhancing the sample geometry [1][2][3], or the efficiency in taking it from the bone [4][5][6]. More in general, the use of MCDM methods in the design of medical devices has been proposed in the literature, as in [7][8][9].…”

The design of medical devices is challenging, due to strict geometry specifications and criteria belonging to several disciplines. The aim of this paper is to provide a design methodology which seems to lack in the literature of design of biomedical devices. In particular, the case study proposed in this paper concerns with the design of Bone-Biopsy (BB) needle devices. Following the design process of Pahl and Beitz, a functional analysis is carried out, to point out the interfaces between parts of existing BB needles. A morphology matrix is used to generate alternatives for the cannula holder, the core part of the product. Generated alternatives have been ranked and scored by means of the Pugh’s Controlled Convergence method according to the decision makers' opinions. In this work, the design peculiarities related to the BB needles which have been pointed out could be extended for guiding the design of other biomedical devices.
