A surgical instrument system includes a surgical instrument, a power supply, and an accessory. The surgical instrument has a first induction device positioned therein. The power supply is electrically coupled to the first induction device. The accessory is selectively operably couplable to the surgical instrument. The accessory includes a second induction device that is inductively coupled with the first induction device when the accessory is operably coupled to the surgical instrument such that the power supply provides power to the accessory.

A surgical instrument for use with a robotic system that has a control unit and a shaft portion that includes an electrically conductive elongated member that is attached to a portion of the robotic system. The elongated member is configured to transmit control motions from the robotic system to an end effector.

A handheld device includes an electronic instrument and a capacitive power supply for storing and delivering power to the electronic instrument. The capacitive power supply includes at least one capacitor, and an electronic circuit operable to boost a voltage from the capacitor to a higher voltage for use by the electronic instrument. The capacitive power supply can be rapidly recharged. Some configurations include an accelerometer which permits the handheld device to detect movement and perform various operations responsive to detected movement. A dual charging station is also disclosed.

A steerable laser probe may include a handle having a handle distal end and a handle proximal end, an actuation control of the handle, a housing tube having a housing tube distal end and a housing tube proximal end, a first housing tube portion having a first stiffness, a second housing tube portion having a second stiffness, an optic fiber disposed within an inner portion of the handle and the housing tube, and a cable disposed within the housing tube and the actuation control. A rotation of the actuation control may be configured to gradually curve the housing tube and the optic fiber. A rotation of the actuation control may be configured to gradually straighten the housing tube and the optic fiber.

A sterile interface for a surgical platform is provided, optionally to be used with a mechanical telemanipulator. The sterile interface is configured to allow for transmission of motion without dimensional inconsistencies between a non-sterile surgical platform and a sterile surgical instrument that are related to one another in a master-slave configuration. The sterile interface is configured to allow for multiple changes of sterile surgical instruments during a surgical procedure without contaminating the sterile field. The sterile interface allows for interchangeable sterile articulated surgical instruments to be attached to the surgical platform without coming into contact with non-sterile portions of the surgical platform.

A medical or dental treatment device comprises a tool retainer, a measuring coil and an evaluation device. The tool retainer can be connected to a plurality of different tools. The measuring coil can be supplied with a periodic electrical energy. The evaluation device can be connected to the measuring coil for detecting whether a tool is connected to the treatment device or which of a plurality of tools is connected to the treatment device. On the basis of an electromagnetic (e.g., inductive) coupling between the tool accommodated in the tool retainer and the measuring coil supplied with the periodic energy, a periodic measurement signal specific to each tool can be generated and assigned by the evaluation device to the tool. The evaluation device determines the phase shift of the electrical voltage and of the electric current of the periodic measurement signal.

Medical device for transcatheter heart valve repair comprising a grasping tweezer (1) and a plicating tweezer (2), said grasping tweezer (1) being adapted to grasp a leaflet rim (3) and said plicating tweezer (2) comprising two rotatable flaps (4,5) and a central shaft (6) around which said flaps (4,5) may rotate in a “butterfly manner”, in such a way that the plicating tweezer (2) may adopt a closed or an open configuration. The invention also relates to a method for using this medical device.

A surgical assembly includes a surgical instrument and a holder. The surgical instrument includes an elongate body and an end effector. The elongate body has a proximal portion and a distal portion that defines a longitudinal axis therealong. The proximal portion is movable relative to the distal portion between a first condition and a second condition. In the first condition, the proximal portion is parallel to the longitudinal axis. In the second condition, the proximal portion is non-parallel to the longitudinal axis. The holder is configured to be coupled to the elongate body to selectively retain the proximal portion of the elongate body in the first condition.
