A surgical tool for resecting bone includes a pneumatic motor to which a bearing tube is secured for rotatably supporting a resecting tool. The bearing tube is eccentrically disposed within an attachment tube, with a flow channel defined between an interior of the attachment tube and an exterior of the bearing tube. Irrigation fluid is passed through the flow channel to maintain a constant flow of irrigation fluid about a cutting end of the resecting tool. Optical fibers extend within the attachment tube for passing light to lenses disposed at the specimen end of the attachment tube for providing illumination. At least one optical fiber extends from a lens at the specimen end, through the attachment tube, and to an optical viewer for providing a means for inspecting the bone being resected. The attachment tube is slidably adjustable along the bearing tube for selecting a distance between the specimen end of the attachment tube and the cutting end of the resecting tool.

A surgical resection tool of the type having a rotary motor, a dissecting tool and a bearing tube is provided with dual quick releases for quickly releasing and latching dissecting tools and bearing tubes to expedite tooling changes during surgical procedures. The surgical resection tool preferably has a canted centerline in which the centerline for the rotary motor is canted with respect to the centerline for the dissecting tool and the bearing tube to provide an ergonomic shape for holding the resection tool. In a preferred embodiment, the two quick releases are provided by collet type latches having latching balls and slidable sleeves. The slidable sleeves are coupled together for selectively moving to a latching position where latching balls are pressed into grooves formed into dissecting tools and bearing tubes to latch a dissecting tool and a bearing tube into the resection tool. The slidable sleeves are moved to a second position to allow the latching balls to release from within the grooves so that dissecting tools and bearing tubes may be quickly replaced.

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.

A surgical instrument has a motor including a chuck for releasably receiving a dissecting tool for rotation about an axis of the surgical instrument. The dissecting tool has a cutting end and a shaft and the surgical instrument is provided with a base releasably connected to the motor. A sleeve is releasably connected to the base to support the shaft of the dissecting tool, and the surgical instrument is further provided with sleeve connection means for selectively permitting axial movement of the sleeve relative to the base and the dissecting tool to vary the amount of protrusion of the cutting end of the dissecting tool from the sleeve.

A dissecting device assists in removing a prosthesis from an embedded engagement within a bone. The device includes a cutting tool having a cutting tip and an elongated shank which has a diameter and length selected so as to allow significant lateral flexing. A motor configured to be gripped by one hand of a user, is connected to the cutting tool shank for providing rotational motion to the cutting tool. A handle configured to gripped by another hand of the user has a bearing carrier having a hole therethrough which rotatably receives the shank. The user will move the motor and the handle to guide the cutting tool around the perimeter of the prosthesis to dissect a thin layer between the prosthesis and the bone to release the prosthesis from the bone.
