摘要： A surgical instrument operable to sever tissue includes a body assembly and a selectively coupleable end effector assembly. The end effector assembly may include a transmission assembly and an end effector. The body assembly includes a trigger and a casing having a distal aperture configured to receive a portion of the end effector assembly. First and second coupling mechanism portions cooperatively couple the end effector assembly to the body assembly for use. A cartridge positionable between the instrument and a generator includes information regarding operating parameters unique to the selectively coupleable end effector assembly and/or the desired surgical procedure, such as information regarding setting a maximum current set point within an ultrasonic transducer. The instrument is programmable with operating parameter information while within a sealed and sterilized packaging unit.

摘要： A surgical apparatus comprises an instrument body, an end effector, and a control module. The end effector is in communication with the handle assembly. The end effector is operable for use in a surgical procedure. The control module is in communication with the end effector. The end effector with the control module is able to deliver surgical energy as well as nerve excitation energy to a surgical site. A surgeon may detect stimulation of nervous tissue by visually observing the tissue twitch, and may adjust surgical technique accordingly. A sensor may be used to detect excitation of nervous tissue based on excitation caused by the nerve excitation energy.

摘要： A surgical instrument comprises a body assembly and an end effector. The body assembly includes a control module, an orientation sensor communicatively coupled to the control module, and an energy component. The energy component is operable to activate the end effector at a plurality of energy settings. A storage device is communicatively coupled to the control module and includes a plurality of gesture profiles and corresponding energy settings. The control module is configured to set the energy setting of the energy component to a corresponding energy setting in response to a correlation between the output of the orientation sensor and a gesture profile. In some versions, the control module modifies the energy setting based upon output from a force sensor that measures the force on the end effector. The control module may also decrease the energy setting in response to an anomalous acceleration or deceleration detected by an accelerometer.

摘要： An electrosurgical device comprises an end effector, a cutting member, and en electromechanical driver. The end effector comprises a pair of jaws that clamp tissue. The jaws include electrodes that deliver RF energy to clamped tissue. The cutting member cuts tissue clamped between the jaws. The electromechanical driver drives the cutting member. A control module commands the electromechanical driver, and regulates the delivery of RF energy to the electrodes, based on a combination of user input and feedback signals from the electrodes and from the electromechanical driver. The device may provide tactile feedback to the user through the user input feature, based on a load encountered by the cutting member. The device may alert the user when the exterior of end effector makes incidental contact with tissue, to avoid inadvertently burning the tissue. The device may include a removable battery pack to power the electromechanical driver and the electrodes.

摘要： An apparatus maintains the sterility of a medical device while providing for the insertion of an insertable component into the medical device. The apparatus includes a medical device having a housing sized to contain the insertable component, an active feature, a cap, and a hinge member. A container encases the medical device within a device recess, a cap recess, and a container cover. The insertable component may be inserted into the housing while limiting potential contact with the exterior of the medical device. An alternative assembly comprises an insertion assembly having a handle and the insertable component detachably attached thereto. The medical device comprises a housing, an active feature, and a flexible member. An insertion tube is insertable within the flexible member to limit contact when the insertable component is inserted into the housing. Yet another configuration includes a resiliently hinged door assembly releasable by a release button.

摘要： In various embodiments, a surgical instrument for operation in an aqueous environment is provided. In at least one embodiment, the surgical instrument may include a hollow sheath and a blade disposed at least partially within the sheath. Coupled to the blade may be at least one ultrasonic transducer, which, in turn, may be coupled to a drive system. The drive system may be configured to deliver gross axial motions to the blade such that the blade translates with respect to the hollow sheath when the drive system is activated. Accordingly, tissue may be cut by the blade with gross axial movement of the blade and/or ultrasonic vibrational motion provided by the ultrasonic transducer(s). In alternative embodiments, the blade may be rotated axially instead of translated with respect to the hollow sheath.
