A surgical tool that includes a nose through which a cutting accessory extends. The nose is formed with an enclosed channel through which irrigating fluid is flowed. The enclosed channel has a helical shape such that as the channel extends longitudinally along the nose, the channel curves around the nose and the cutting accessory disposed in the nose.

An instrumentation kit for use in preparing a bone to receive a prosthetic component includes at least one first combination device, the at least one first combination device including a proximal portion configured to couple with a torque providing device and a distal portion configured to couple with a first instrument, the at least one first combination device pivotable between a first position whereat the proximal portion and the distal portion are (i) longitudinally aligned and (ii) configured to transfer a torque received by the proximal portion to the distal portion, and a second position whereat the proximal portion and the distal position are (i) not longitudinally aligned and (ii) configured to transfer a torque received by the proximal portion to the distal portion.

An angled instrument assembly includes an angled sleeve, a driver shaft, and a tool bit. The angled sleeve includes a straight passage segment that meets an angled passage segment at a junction. The junction includes an inner elbow and an outer elbow. Material is removed from the inner surface of the inner elbow in order to improve the ease with which the driver shaft can be moved in and out of the angled sleeve. The assembly can also include drafted female or male engagement bodies for facilitating the engagement and disengagement of the tool bit with a tool bit engagement assembly located at the distal end of the driver shaft.

A drill bit comprising a cutting portion having an edge for penetrating bone and a resilient tine configured to be inserted into a drill housing, the resilient tine including a tab having an abutment surface configured to establish a snap-fit connection with a drill gear within the drill housing, and wherein the drill bit is capable of being removed from the drill housing by disengaging the abutment surface from the drill gear.

This disclosure relates to reaming assemblies and methods for repairing bone defects. The reaming assemblies disclosed herein may be utilized for removing bone prior to positioning a graft and/or implant at a surgical site.

Disclosed herein is a surgical device. The surgical device includes a cutting burr, a flexible/deflectable shaft, an elongated fluted shaft, a sheath, and an outer tube. The cutting burr has a fluted extension. The flexible/deflectable shaft has a distal end and a proximal end, the distal end is configured to be connectable to the fluted extension of the cutting burr. The elongated fluted shaft is configured to be connectable to the proximal end of the flexible shaft. The sheath is configured to receive all or portion of the flexible shaft and the elongated fluted shaft. The outer tube is configured to receive the sheath such that there is enough space for fluid irrigation between the outer tube and the sheath.

A system for intramedullary preparations comprises a directional reamer including a flexible drive shaft having a proximal end and a distal end, and a cutting head operably connected to the distal end of the flexible drive shaft. The system further includes a means of displacing the distal end of the flexible drive shaft and deflecting the cutting head to selectively shape a medullary canal in a bone. A follower sleeve is also include in the system and has a proximal end and a distal end in the form of a collar, with the follower sleeve being configured to accept the flexible drive shaft. The system additionally includes a reaming plunger that extends through the follower sleeve and is positioned adjacent to the flexible drive shaft such that the reaming plunger engages the collar of the follower sleeve to deflect the cutting head.

A medical device for implantation in a hip joint of a human patient, the natural hip joint having a ball shaped caput femur as the proximal part of the femoral bone with a convex hip joint surface towards the center of the hip joint and a bowl shaped acetabulum as part of the pelvic bone with a concave hip joint surface towards the center of the hip joint. The medical device comprising; an artificial caput femur, comprising a convex surface towards the center of the hip joint. The artificial convex caput femur is adapted to, when implanted: be fixated to the pelvic bone of the human patient, and be in movable connection with an artificial acetabulum surface fixated to the femoral bone of the patient, thereby forming a ball and socket joint. The medical device further comprises a fixation element comprising a fixation surface adapted to be in contact with the surface of the acetabulum and adapted to fixate the artificial convex caput femur to at least the acetabulum of the pelvic bone.

Disclosed herein is a tool assembly for use with an energy applicator having a shaft extending along an axis between a proximal end and a distal end. The tool assembly comprises a support structure to support the energy applicator, and a connector assembly arranged to engage and releasably lock the energy applicator to the support structure in a locked state. A drive system is coupled to the support structure and is configured to rotatably drive the shaft of the energy applicator about the axis. The drive system comprises a counterweighted clutch assembly.

An anchor delivery system includes both a straight and curved drill guide along with a flexible drill, a flexible obturator and a flexible anchor inserter. The curved drill guide has a distal tip with approximately a 15° bend from the primary axis of the drill guide. Both the drill and the obturator have a reduced diameter section to improve flexibility during passage through the curved drill guide. Additionally, a surface of the inserter shaft has a laser cut pattern which permits flexing of the inserter around the inner diameter of the curved drill guide.
