A handle for a surgical tool including a shaft having a proximal end and a distal end with a gripping handle affixed to the proximal end of the shaft. A bushing is attached to the distal end of the shaft, the bushing including a plurality of flexible members circumferentially spaced apart. The handle further includes a sleeve circumscribing the shaft and the bushing. The sleeve is moveable between a first position substantially covering an entirety of the bushing and a second position spaced from a most distal end of the bushing.

An apparatus for releasably holding a surgical tool having a body, the body having a longitudinal axis, a monolithic construction, and a shape apportioned to be grasped by a human hand, with body further having a tool engaging portion, a hand receiving portion, and a button pressing portion. A longitudinal bore is disposed along the longitudinal axis of the body, and on one end. A transverse bore is disposed through the body into the longitudinal bore, with the transverse bore disposed such that the longitudinal axis of the transverse bore intersects the longitudinal axis of the longitudinal bore. A button disposed on and pivotably attached at a resilient member to the button pressing portion of the exterior of the body, with the button being proximal to the tool engaging portion. The button has a button bore and a boss extending from the button bore into the transverse bore which is alignable with the longitudinal bore. The button is disposed on the body to be thumb pressable, the button suitable for selectively engaging a corresponding groove on surgical tool.

A surgical instrument comprises a hand-held portion configured to be manipulated by a user and a pivoting portion operatively coupled to the hand-held portion. The pivoting portion is configured to pivot with respect to the hand-held portion according to first and second degrees of freedom. The pivoting portion includes an accessory drive motor, an accessory drive member configured to be driven by the accessory drive motor, a plurality of lead screws, a carriage including a central aperture axially extending through the carriage and configured to interface with and linearly translate along the plurality of lead screws, and a linear drive motor configured to rotate the plurality of lead screws to linearly translate the carriage relative to the hand-held portion with respect to a third degree of freedom. The accessory drive member extends through and is configured to move within the central aperture of the carriage.

Medical devices for creating or expanding a cavity within bone of a patient are disclosed. In some circumstances, a medical device, such as an osteotome is designed to facilitate simultaneous advancement and articulation of a distal portion of the osteotome. Simultaneous advancement and articulation of the distal portion may reduce one or more forces on the distal portion of the osteotome relative to other methods in which advancement and articulation are separated in time, thereby decreasing the risk of breakage or other damage to the osteotome.

Described are systems, targets, and methods for registering a tool for use in optical tracking. A first target and a second target are attached to the tool, with the first target having a known spatial relationship to the tool or end effector of the tool. By determining a spatial feature of the first target and a pose of the second target, and using the known spatial relationship between the first target and the tool or end effector of the tool, a spatial relationship between the second target and the end effector can be determined. Subsequently the first target can be removed, and the end effector is trackable based on only tracking of the second target. In some implementations, the first target is removably couplable to the tool by the same interface by which the end effector is removably couplable to the tool.

A combination drill guide and depth gauge surgical instrument for use during a surgical procedure to implant an acetabular cup component into a surgically-prepared acetabulum of a patient's hip includes an elongated shaft having a drill guide on an end thereof. The instrument also includes a retractable depth probe that may be used to gauge the depth of the holes drilled by use of the drill guide. A method of using such an instrument is also disclosed.

Reciprocating rasps for the surgical preparation of the bone prior to the implantation of a glenoid or acetabular component with complex geometry are disclosed. Surgical methods for the use of such reciprocating rasps are also disclosed.

Apparatus for use in debriding a bone, said apparatus comprising: an arthroscopic debridement template comprising a body reconfigurable between (i) a first configuration having a first profile and comprising an arc matching the desired curvature of the bone after debridement, and (ii) a second configuration having a second profile, wherein said second profile is smaller than said first profile.

A device for sterile coupling of a percutaneous surgical instrument to a rotary drive tool (5). The device has a flexible envelope (1) intended to confine the drive tool (5), a connector piece (3) for coupling to the percutaneous surgical instrument via one end and to the drive tool (5) via its other end by passing through the envelope via an opening (12), and also a tubular ring (2) positioned on the inner surface of the envelope (1) in the area of the opening (12) and configured to rigidly connect the envelope (1) to the body of the drive tool (5). The connector piece (3) is configured to be able to pass through the ring and turn freely inside the ring when driven by the rotary drive tool (5). The connector piece (3), the ring and the envelope have means (22, 34, 14) which interact in order to form a leaktight barrier between the inside and the outside of the envelope (1) in the area of the opening (12).
