Piezoelectric osteotomy devices and corresponding systems and methods for removing an acetabular cup or shell from a patient's acetabulum are disclosed. In one embodiment, the piezoelectric osteotomy device includes a piezoelectric element to actuate a cutting tip on an armature. In some such embodiments, the cutting tip may be extended and/or retracted to facilitate cutting of bone around an acetabular cup. The armature may include a fluid output port located proximate the cutting tip to mitigate heat generated by the cutting tip. In one embodiment, the piezoelectric osteotomy device is arranged and configured to provide constant current adjustment.

Embodiments directed to an apparatus and system of monitoring an instrument with a working tool engaged thereby. In one aspect, an embodiment including a working tool with a machine readable indicium indicative of a working tool attribute. The working tool may be receivable by an instrument such that a corresponding machine readable indicia reader receives an identifier of the working tool. Various attributes and conditions in relation to the instrument and working tool received thereby may be identified to facilitate the provisioning of a response to prompt various corrective actions. In this regard, a controller may provide an output in response to a received identifier of a working tool and an identified instrument operating condition.

A surgical stapling system for stapling the tissue of a patient is disclosed. The stapling system comprises a housing, a shaft extending from the housing, and an end effector extending from the shaft. The end effector comprises a plurality of staples removably stored therein and, also, an anvil configured to deform the staples. The stapling system further comprises a firing mechanism configured to deploy the staples along a staple firing path longer than 60 mm, a camera configured to capture an image of the patient tissue, a display, and a controller configured to generate an image of the staple firing path, wherein the images are displayed on the display.

A stimulation device includes an adapter component to increase the usability of the stimulation device. The adapter may be a bipolar adapter arranged to connect to the housing of the stimulation device. The adapter may include a clip having a first channel configured to receive an operative element therein and a second channel having a return operative element therein. The return operative element is in electrical communication with an electrical circuit of said stimulation control device. Alternatively, the adapter may be a percutaneous adapter comprising a connector configured to connect to an operative element of a stimulation device and a lead wire connected to the connector. A needle may be connected to the lead wire to deliver a electrical stimulation signal to a target tissue located beneath the skin of a subject patient.

In a particular implementation, an apparatus configured to measure bone temperature during drilling includes a processor and an infrared (IR) sensor coupled to the processor and configured to measure temperature data indicating a temperature at an interface between a drill bit and a bone of a patient.

An example method includes obtaining, a virtual model of a portion of an anatomy of a patient obtained from a virtual surgical plan for an orthopedic joint repair surgical procedure to attach a prosthetic to the anatomy; identifying, based on data obtained by one or more sensors, positions of one or more physical markers positioned relative to the anatomy of the patient; and registering, based on the identified positions, the virtual model of the portion of the anatomy with a corresponding observed portion of the anatomy.

A powered surgical handpiece including a housing, a printed circuit board, a sensor, and an actuator assembly. The housing has a longitudinal axis extending from a first end to a second end of the housing. The printed circuit board has a first face and a second opposing face. The first and second faces extend perpendicular to the longitudinal axis. The sensor is coupled to the first face of the printed circuit board. The sensor is centered along the longitudinal axis of the housing. The actuator assembly includes a lever and an actuator. The lever is pivotally coupled to the housing. The lever maintains a magnet slidably positionable along the lever. The magnet is positionable to be proximal to the sensors.

A surgical system for operating on a bone of a patient is described. The surgical system includes a reference device including one or more radiopaque markers, a first sensor configured to generate a first signal pertaining to orientation data of the reference device relative to a first coordinate system, a surgical instrument for coupling to an end effector, a second sensor configured to generate a second signal pertaining to orientation data of at least one of the end effector and the surgical instrument relative to a second coordinate system, and a navigation system. The navigation system is configured to determine an orientation of at least one of the end effector and the surgical instrument and superimpose a virtual representation of at least one of the end effector and the surgical instrument over the image based on the determined orientation and user input.

A tissue cutting probe includes an outer sleeve assembly, an inner sleeve assembly, a burr and an electrode. Each of the inner and outer sleeves has a proximal end, a distal end, and central passage extending therebetween. The inner sleeve assembly is coaxially and rotatably received in the central passage of the outer sleeve assembly, and the burr has a plurality of metal cutting edges carried on a first side of the distal end of the inner sleeve assembly. The electrode is carried a second side of the distal end of the inner sleeve assembly.

A number of improvements are provided relating to computer aided surgery. The improvement relates to both the methods used during computer aided surgery and the devices used during such procedures. Some of the improvement relate to controlling the selection of which data to display during a procedure and/or how the data is displayed to aid the surgeon. Other improvements relate to the structure of the tools used during a procedure and how the tools can be controlled automatically to improve the efficiency of the procedure. Still other improvements relate to methods of providing feedback during a procedure to improve either the efficiency or quality, or both, for a procedure.
