    Abstract: A surgical instrument (1200) comprises a hand-held portion (1204) configured to be manipulated by a user and a pivoting portion (1202) operatively coupled to the hand-held portion and a drive motor. 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 a telescoping nose mechanism (1222) including a nose tube (1212) and an intermediate unit (1228). The intermediate unit includes a plurality of threaded lead screws (1238) and has a carriage (1242) threaded for interfacing with the lead screws to enable rotation of the lead screws, such that the carriage linearly translates along the lead screws to linearly translate the nose tube enabling telescoping of the nose tube relative to the hand-held portion with respect to a third degree of freedom.

    Abstract: 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 a telescoping nose mechanism including a nose tube, an intermediate unit having a carriage extending from the nose tube to enable linear translation of the nose tube, and a drive motor cooperating with the carriage to linearly translate the nose tube relative to the hand-held portion with respect to a third degree of freedom.

    Abstract: A surgical instrument (1200) comprises a pivoting portion (1202), a shaft (1224) disposed in said pivoting portion (1202), a first drive motor (1216) disposed in said pivoting portion (1202) and being configured to rotate said shaft (1224), and a second drive motor (1226) disposed in said pivoting portion (1202) and being configured to linearly translate said shaft (1224). Said second drive motor (1226) includes a rotor (1230) and a drive gear (1236) each defining an aperture (1232) extending therethrough to receive said shaft (1224) and to enable said shaft (1224) to freely rotate and linearly translate therethrough.

    Abstract: A system comprises an instrument adapted to be manually supported and moved by a user. Said instrument includes a hand-held portion, a working portion movably coupled to said hand-held portion, a plurality of actuators operatively coupled to said working portion for moving said working portion in a plurality of degrees of freedom relative to said hand-held portion, and a tracking device attached to said hand-held portion for tracking said instrument. Said system further comprises a navigation system for determining a position of said working portion relative to a target volume of tissue to be remove, and a control system in communication with said actuators to control said actuators to move said working portion relative to said hand-held portion such that said working portion autonomously follows a path defined in said control system to remove material of the target volume while the user maintains said hand-held portion in a gross position relative to the target volume.
