摘要： An acetabular reaming system is disclosed of the type having a driver and a tool held together by a quick-release coupling mechanism. The tool (10) has a hollow body (12) defining a domed shape with a rotational axis (14), an apex (16) aligned with the axis (14) and a hemispherical wall (18) extending from the apex (16) to an equatorial rim (20) spaced 90 degrees from the axis (14). The rim (20) has an edge (22) visible to the user that indicates the position of the tool (10) relative to the bone. A first plurality of cutting sites (24) is arrayed along the body (12) and a second plurality of cutting sites (28) is arrayed circumferentially along the edge (22). Preferably, the first plurality of cutting sites (24) present raised first teeth (30, 130, 230, 330) having a profile selected from continuous squared (30), continuous rounded (130), discontinuous squared (230) and tongued (330) profiles. Also preferably, the second plurality of cutting sites (28) present raised second teeth (32, 132, 232, 332, 432) selected from continuous squared (32), continuous rounded (132), discontinuous squared (232), tongued (332) and bladed (432) profiles.

摘要： An adjustable reamer spindle is provided to aid the surgeon in controlling the instrument. The reamer spindle is easily disassembled for cleaning. The spindle has a repositionable handle, a locking ring, and an elastic device. The elastic device biases against a handle locking mechanism that locks the repositionable handle at angular positions about an axis of the spindle. The elastic device further biases a locking ring into a locked position. The locking ring aids in holding the reamer spindle together. Removal of the locking ring against an elastic bias of the elastic means unfastens an end of the assembly in order to facilitate disassembly and/or cleaning. Adjustment of the position of the handle about the spindle enables the palm/grip of each hand to be changed in order to provide maximum control in different orientations. The adjustment is desirable in order to accommodate operating on the left or right side of the patient, standing behind or in-front of the patient, or the use of a different surgical approach. Further, adjustment is important to accommodate the differing needs of surgeons who are naturally left or right handed.

摘要： A reamer system is provided which includes a cannulated reamer holder, and a corresponding cannulated reamer, which, when assembled and operated over a drill pin secured in a manner axially aligned with the stem of the femoral joint, enables the accurate and controlled reshaping of the femoral joint. The reamer is made up of a cutting form and a central guide, in which the guide is supported at the center of the cutting form by a bar structure. The bar structure includes portions which connect to and extend radially between the central guide and a peripheral edge of the cutting form.

摘要： A rotary surgical reamer assembly for removing bone and tissue from a joint to facilitate the installation of a prosthetic device. The assembly includes a hollow reamer body having an opening and a base portion. The base portion includes a first pivoting link member, a wall with a surface defining a central cavity, and a plurality of spaced apart cutting sites defining apertures through said wall. A shaft is configured to be de-mountably attached to a rotary source of power. The shaft has a rotary axis and a second pivoting link member coupled to the first pivoting link member. The axis of the shaft forms an angle to the base portion. A mechanism adjusts the angle of the hollow reamer body from an un-deployed position to a deployed position.

摘要： A surgical instrument holder (10) is made up of a head assembly (68) and a drive spindle assembly (42). The head assembly (68) has a shank (12) with a first driveable end (14) and second coupling end (16). The second end has a coupling device (20) having an interface (22) for receiving a surgical instrument (24). The instrument (24) is held in functional assembly to the shank by a releasable locking mechanism (26). The releasable locking mechanism (26) is made up of a locking ring (30) slideably disposed about the shank, a spring (32) biased against the coupling device (20) by the locking ring, and a connection ring (34) retaining the locking ring in a fixed position during use. The drive spindle assembly (42) is connected to the head assembly (68) so as to transmit torque therethrough. The spindle assembly (42) has an elongated drive spindle (40), high precision bearings (44, 120, 122) and a cylindrical tube (46). The drive spindle (40) is releasably mounted to an end (36) of the spindle assembly and is supported for rotation within the cylindrical tube (46) by the high-precision bearings disposed therebetween and held in place at least in part by the shank (12). The bearings (44) precisely control the position of a surgical instrument (24) affixed thereto. The connection ring (34) provides a common quick-release connection with the head assembly (68) and the drive spindle assembly (42), such that unlocking of the connection ring (34) enables quick disassembly of the connection ring, spring (32), locking ring (30), and drive spindle assembly (42) for cleaning and component sterilization.

摘要： An acetabular reamer for surgical use includes (a) a substantially hemispherical dome defining an equatorial plane, and (b) a reamer spindle interface structure fixedly attached to the inside of the dome so as to substantially inset the interface structure within the dome. This insetting of the interface structure helps minimize the size of an assembly of the reamer and a reamer spindle when performing minimally invasive joint surgery.
