A mounting apparatus (3) of the present invention is used in a medical environment to releasably secure a device (5) to a support member (S R PS). The mounting apparatus (3) has a flexible shaft (43 125 139 279) with a first end (45 275) for releasable attachment to the support member (S R PS) and a second end (47 131) for releasable attachment to the device (5). A generally C-shaped clamping member (41 217 273) at the first end (45 275) releasably attaches the apparatus (3) to the support member (S R PS). The clamping member (41 217 273) has an inner surface (161 317), an outer surface (165 225 301), and at least two apertures including a first aperture (177, 199) through which a securing rod (51) passes and a second aperture (179 315) for releasable attachment of the flexible shaft (43 125 139 279). The present invention is also directed to a powered medical device assembly (1) having a medical device (5) and a flexible shaft (43 125 139 279) capable of selective mounting of the medical device (5) on a support (S R PS).
