Abstract
A battery pack (10) is disclosed for use with a medical instrument (12). The battery pack includes a housing (14), defined by a case (16) and cover(18). The housing includes a storage section (22), for receiving batteries (78 and 80), and a connector section (24) on one side of the storage section for cooperating with a latch assembly (110), ejection spring (142), and electrical connectors (108) provided adjacent a battery tray (98) on the instrument. Specifically, the connector section includes an aligned latch surface (64), ejection surface (62), and electrical connectors (86) that cooperatively engage the latch assembly, ejection spring, and connectors on the instrument. As a result, the battery pack can be quickly, easily, and effectively attached to the instrument, in spite of the side-mounted nature of the connector section. Further, the relative weight and alignment of the battery pack and instrument are such that the center of mass of the instrument, with a battery pack inserted into the tray, is aligned with the instrument's handle (96).
