A medical device may include a handpiece having a housing and a drive system arranged within the housing. The drive system may be adapted to operate a tool in direct contact with human matter of a patient at a treatment site. The device may also include a suction system integrated into the drive system and configured to remove human matter from the treatment site. The device may also include a motor removably attached to the housing and configured for delivering rotational power to the drive system while avoiding contact with the human matter.

The present disclosure relates generally to a surgical system. The surgical system comprises one or more surgical instrument assemblies and a surgical navigation system. The surgical instrument assemblies comprises a tracking device capable of being tracked by the surgical navigation system. The surgical system is also configured to allow the user to define one or more alert zones relative to anatomical structures of the patient and/or a surgical pathway. The surgical system further comprises an alert device in communication with the surgical navigation system, such that the alert device is configured to provide a user-perceptible alert to the surgeon or medical professional based on the position of the surgical instrument, as determined by the surgical navigation system, relative to the defined alert zones and/or surgical pathway.

A surgical instrument handpiece for a surgical instrument, a corresponding surgical instrument, a corresponding medical product set having the surgical instrument handpiece in combination with at least one accessory, a corresponding rinsing device, and a corresponding cleaning method for the internal flushing of the surgical instrument handpiece. The surgical instrument handpiece includes a handle section for proximal handling by an operator and a shaft section that extends from the handle section in a distal longitudinal direction. A tool is arranged or arrangeable by a user in a distal outlet opening of the shaft section at the distal end opposite the handle section. The shaft section has at least one narrowed distal tip section with a reduced cross-sectional area in the region of the distal outlet opening.

Example embodiments disclosed herein encompass disposable cover systems for a power tool, as well as covers, components, and methods. A disposable cover system may include a cover defining an inner cavity to receive a power tool and an aperture through which a pass-through to transmit movement from the power tool to outside the cover is extendable. Trapping a portion of a cover which surrounds the aperture, between first and second compressible members for example, may form a seal around the aperture. Transmission components including a pass-through, adapters to adapt a cover to a transmission component, multi-part devices to create an aperture, and related methods are also disclosed.

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.

A system for drilling a bore in a bone (7) and measuring a depth of the bore during surgery, said system comprising: a drill (5) comprising a drill chuck (6) for holding a drill bit; a drill bit (3) mounted in the drill chuck; at least one sensor (11,12) arranged to produce signals for determining the depth of the bore, preferably comprising a strain gauge (11) arranged to produce a signal representing a force exerted on the system during drilling, and a distance sensor (12) arranged to produce a signal representing a distance between a reference point on the system and the bone surface during drilling; first communication means (19) arranged to communicate said signals to electronic processing means; electronic processing means (16) arranged to receive said signals from said first communication means and to determine a depth of a bore from said signals; second communication means (13a) arranged to communicate said determined depth to output means; output means (2) for outputting information about the determined depth of the bore received from said second communication means; wherein said drill bit is part of a rotatable drill bit unit (1), which may or may not comprise said drill chuck; and said at least one sensor and one of said first and second communication means are mounted in the drill bit unit.

A fixed angle instrument includes an elongate guide extending from a proximal end to a distal end, the guide having a proximal portion extending along a longitudinal axis and a distal portion extending transverse to the longitudinal axis. The instrument further includes a shaft disposed within the guide extending through the proximal portion of the guide along the longitudinal axis. The instrument further includes an intermediate element coupled to the shaft, the intermediate element having at least one bulbous link. The instrument further includes a distal element coupled to a distal end of the intermediate element.

A surgical tool that has a pair of transmissions coupled to one another to effect driving of a cutting tool in both bidirectional intermittent rotational manners and in opposite directions of continuous rotation. The transmissions are driven by a motor coupled to one of the transmissions which is coupled to the second transmission.

A surgical system comprises a handpiece and a battery. The handpiece includes a body and a handpiece connector operatively coupled to the body, the handpiece connector including a first coupler. The battery includes a housing, a rechargeable cell for storing an electric charge, and a battery connector operatively coupled to the housing, the battery connector including a second coupler configured to rotatably engage the first coupler. The second coupler receives the first coupler along an axis at an initial radial position where relative axial movement between the battery and the handpiece is permitted and permits rotation of the battery relative to the handpiece from the initial radial position to a first secured radial position and a second secured radial position. Relative axial movement between the battery and the handpiece is constrained in the first secured radial position and in the second secured radial position.

Disclosed is an instrument assembly usable in a procedure. The instrument includes a connection for a working portion and to a tool handle. The assembly includes a method and system for interconnection and/or identification of the working portion and the handle. The instrument may also include various trackable features to allow for a navigated procedure.
