摘要:
A surgical instrument includes a handle assembly, a battery pack, and a cooling device. The battery pack is operable to power the surgical instrument and may be inserted into the handle assembly. The cooling device is mechanically integrated with the battery pack. The cooling device is further operable to draw heat away from the battery pack while the battery pack delivers power to the surgical instrument.

Various embodiments are directed to surgical instruments for use in handheld applications or with robotic surgical systems. The surgical instruments may comprise an end effector to treat tissue and a shaft extending proximally from the end effector along a longitudinal axis. Some embodiments may be usable with an instrument mounting portion of a robotic surgical instrument. For example, the shaft may extend proximally to the instrument mounting portion.

A surgical instrument includes a handpiece having a user input feature and a user feedback feature. A shaft assembly extends distally from the handpiece. An end effector is disposed at a distal end of the shaft assembly. The end effector includes an active feature responsive to actuation of the user input feature. The active feature is operable to operate on tissue in response to actuation of the user input feature. The user feedback feature is operable to provide feedback to the user that indicates information relating to operation of the end effector. The feedback may include haptic, visual, and/or auditory feedback.

An apparatus for powering a medical device includes a battery pack, a connection feature on the battery pack, and a protective layer. In some versions the protective layer covers the battery pack and the connection feature to provide a fluid tight seal. In some versions, the connection feature comprises at least one electrode, which may pierce the protective layer to establish electrical communication with the medical device from within the protective layer such that a non-sterile battery pack could be used to deliver power to a sterile medical device without compromising sterility of the medical device. The protective layer may form a compartment. The at least one electrode may have a conical shape to facilitate piercing the protective layer.

In one general aspect, various embodiments are directed to an ultrasonic surgical instrument that comprises a handpiece housing that rotatably supports an ultrasonic transducer assembly therein that may be selectively rotated by various motor configurations. Various slip ring arrangements are disclosed for supplying ultrasonic electrical signals and motor drive signals from a control system. Various forms of blade and cutting implements are disclosed for attachment to the ultrasonic transducer assembly such that such implements may be selectively rotatable within a hollow outer sheath. Vacuum may be applied to the cutting implement or through the outer sheath to draw tissue through an opening in the sheath and into contact with the cutting implement.
摘要:
A surgical instrument includes a temperature sensor and a control unit that is operable to deactivate an end effector of the surgical instrument. In some versions the temperature sensor detects the temperature of a transducer, while in others the temperature sensor detects the temperature of the end effector. The surgical instrument may also include a trigger and a trigger position sensor. A force sensor or a position sensor may be included to determine the force and/or position of the transmission assembly. The end effector may also include a force sensor or a micro coil. A surgical instrument having a sensor may be included in a surgical system that includes a control unit and a remote controller. In some instances the remote controller may have one or more force-feedback components. In addition, a device interface and a surgeon interface may be included to remotely adjust the settings of the control unit.
