A preferred acetabular reamer is disclosed for cutting a bone socket, defining an apex and rotatable about a drive axis. The reamer has a domed support portion adjacent the apex and a plurality of cutting members, which may be of the cheese grater or bladed type, each pivotally mounted on the support portion. A hub structure including a sleeve portion is movable along the axis toward and away from the apex. A plurality of spokes operatively connects the cutting members and the hub, respectively. Actuation of the hub, in turn, radially collapses the spokes causing the cutting members to assume an insertion profile during passage of the reamer through a surgical incision, and then radially expands the spokes causing the cutting members to assume a larger, cutting profile while reaming the bone socket. A surgical kit and method employing the inventive reamer are also disclosed.

Minimally invasive collapsible surgical reamer

The surgical reamer has a hollow dome with apertures spaced apart arranged in arcs extending from an apex of the dome to the base portion of the dome, and removable teeth positioned in the apertures. Each cutting tooth has a flange that is aligned flush with the external surface of the dome, and a raised cutting edge extending above the flange and the external surface of the dome, and an interior passageway communicating between the outside and inside of the dome. In one embodiment, a base plate is removably secured on the base portion of the dome to provide closure of the central cavity of the dome.

Connector for domed cutting tool

The surgical reamer ( ) has a hollow dome ( ) with apertures ( ) spaced apart arranged in arcs ( ) extending from an apex ( ) of the dome to the base portion ( ) of the dome, and removable teeth ( ) positioned in the apertures. Each cutting tooth ( ) has a flange ( ) that is aligned flush with the external surface of the dome ( ), and a raised cutting edge ( ) extending above the flange and the external surface ( ) of the dome, and an interior passageway ( ) communicating between the outside and inside of the dome. In one embodiment, a base plate ( ) is removably secured on the base portion ( ) of the dome ( ) to provide closure of the central cavity (34) of the dome.

This invention is directed to an improved surgical tool to remove tissue or bone from a bone joint member prior to installing a prosthetic device wherein the device basically comprises a cutting head and a rotary device member. The cutting head comprises a support base coupled to the rotary drive, a hollow shell with one or more slots, and one or more cutting or skiving blades projecting through the slots and supported by the support base.
