A hydraulically powered surgical device (20) includes a surgical instrument (24) having a tool (36) is mounted to one end of a handle (26). A hydraulic actuator (62) is mounted to the opposite end of the handle (26) and is also operatively connected to the tool (36). A source of hydraulic pressure includes a fluid reservoir (46) mounted with respect to an actuating element (21). The actuating element (21) is used to selectively apply a hydraulic pressure to the hydraulic actuator (62), thereby operating the tool (36).

[ What is claimed is:] [1.] A hydraulically powered surgical device comprising:a handle having a longitudinal bore extending therethrough;a tool mounted with respect to one end of the handle;a fluid cylinder mounted with respect to an opposite end of the handle;a rod having one end mounted within the cylinder, the rod having a distal end extending from the cylinder and operatively connected to the tool;a liquid reservoir located remote from the handle and in fluid communication with the cylinder; anda control element located remote from the handle and operatively associated with the liquid reservoir for selectively causing hydraulic pressures to be applied to the one end of the rod within the cylinder to move the rod and operate the tool, the control element comprising a base for supporting the liquid reservoir, and a lever pivotally mounted with respect to the base and having a surface contacting the liquid reservoir so that applying a first force on the lever applies a hydraulic pressure to the one end of the rod in the cylinder.
