The invention relates to a handheld surgical power saw intended to be an integrated surgical tool or an attachment to a motorized surgical tool. The tool consists of two arms that reciprocate in opposite directions at all times. Attached to each arm is a set of cam followers and a saw blade. The arms are driven by a cam with outer surfaces that smoothly undulate between the two sets of cam followers.

Dual-bladed reciprocating bone saw

A surgical instrument includes a conduit, the conduit having a conduit axis defined through a terminal end thereof, and a fluid-powered motor for rotating a dissecting tool, the motor having a longitudinal motor axis. A swivel member is connected in fluid communication between the motor and the conduit. The swivel member comprises a motor portion including a motor face inclined at a selected angle from the motor axis, and a conduit portion including a conduit face arranged oppositely that of the motor face and formed to engage matingly with the motor face. A connection shaft extends from one of the motor face and the conduit face and is engaged rotatably with a connection receptacle formed in another of the motor face and the conduit face. The swivel member is provided so that the motor is rotatable relative to the conduit from an aligned position, wherein the motor axis generally is aligned with the conduit axis, to an angularly displaced position, wherein the motor axis intersects the conduit axis at a selected angle.
