摘要： An electrically energized medical instrument uses one or more drive cables to both actuate mechanical components of a wrist mechanism or an effector and to electrically energize the effector. Electrical isolation can be achieved using an insulating main tube through which drive cables extend from a backend mechanism to the effector, an insulating end cover that leaves only the desired portions of the effector exposed, and one or more seals to prevent electrically conductive liquid from entering the main tube. Component count and cost may be further reduced using a pair of pulleys that are shared by four drive cables.

摘要： A tissue retaining ring for use with a plurality of surgical fasteners mounted within a disposable loading unit utilized during a vascular anastomosis inlcudes a genrally circular, semi-pliable material having a series of alternating loops and arcuate portions. Each of the loops defines an aperture therein which is dimensioned to receive a distal end of one of the plurality of surgical fasteners. When the instrument is fired, the surgical fasteners are simultaneously deformed through the tissue ring and through the tissue. The tissue retaining ring holds the tissue in place along the surgical fastener and reduces the chances of tissue slippage after deformation.

摘要： A cover for an electrosurgical instrument having a wrist structure and an end effector is provided. The cover includes a hollow elongated structure, which includes a tip cover portion and a base cover portion integrally connected to the tip cover portion. The tip cover portion has a distal end with an opening therethrough sized to receive the end effector of the electrosurgical instrument and is composed of a first, electrically insulative material having a flexibility sufficient to allow the end effector to be manipulated while the end effector is received in the opening. The base cover portion is composed of a second material having a higher tear strength than the first material. The tip cover portion and the base cover portion overlap at an overlap region configured to receive the wrist structure of the electrosurgical instrument when the end effector is received in the opening.

摘要： This application is directed to a surgical stapling device for performing circular anastomoses. The surgical stapling device includes a handle portion, an elongated body portion and a head portion including an anvil assembly and a shell assembly. The handle portion includes a rotatable approximation knob for approximating the anvil and shell assemblies and a firing trigger for actuating a firing mechanism for ejecting staples positioned within the shell assembly. The firing trigger forms one link of a two bar linkage provided to actuate the firing mechanism. The anvil assembly includes a tiltable anvil which will tilt automatically after firing of the device and unapproximating the anvil and shell assemblies. The head portion also includes a retractable trocar assembly which is slidably positioned within an anvil retainer and is automatically advanced and retracted upon attachment and detachment of the anvil assembly onto the anvil retainer. A lockout tube is provided and is positioned about an anvil retainer for releasably engaging an anvil assembly. The lockout tube prevents inadvertent detachment of the anvil assembly from the anvil retainer. The surgical stapling device also includes a firing lockout assembly which prevents actuation of the firing trigger until an anvil has been attached to the device and the anvil has been approximated. In one preferred embodiment, the firing lockout assembly includes a trigger lock and a safety bracket which prevents movement of the trigger lock from a locked to an unlocked position until an anvil has been attached to the device and approximated and returns the trigger lock to a locked position after the device has been fired. A tactile indication mechanism is also provided for notifying a surgeon that the device has been fired and for notifying a surgeon that the anvil head has been unapproximated a distance sufficient to permit the anvil head to tilt.

摘要： This application is directed to a surgical stapling device for performing circular anastomoses. The stapling device includes a retractable trocar which is slidably supported by an anvil retainer and movable from a retracted position located within the anvil retainer to an advanced position extending from the anvil retainer. The trocar defines a sensor and is operatively connected to an indicator assembly. The indicator assembly is operatively associated with an anvil assembly such that the indicator will not move from a fire-not ready position to a fire-ready position until an anvil assembly has been mounted to the anvil retainer.

摘要： There is disclosed a surgical instrument and loading unit for performing an anastomosis of first and second blood vessels. The surgical instrument includes a handle assembly and a body portion extending distally from the handle assembly. The detachable loading unit includes an anvil releasably engagable with a distal end of the body portion and having a plurality of fasteners disposed in channels about the circumference of a distal end of the anvil. A pusher is slidably mounted over the anvil such that distal movement of the pusher in response to actuation of the handle assembly cams the fasteners between the anvil and a distal end of the pusher to simultaneously crimp the fasteners about tissue. A method of performing an anastomosis is also disclosed and includes positioning a first vessel in the loading unit and partially inserting the first vessel through an opening in a second vessel. The surgical instrument is subsequently attached to the loading unit and the handle assembly is actuated to crimp fasteners about the first and second vessels to form an anastomosis.

摘要： A medical device may include a surgical instrument and a controller. The surgical instrument may include an end effector component configured to move from a first position to a second position and the controller may be operatively coupled to control movement of the end effector component. The controller may further be configured to command the end effector component to move from the first position toward the second position, and automatically oscillate the end effector component if the controller has not received a signal indicating the end effector has reached a preset location within a predetermined time period after the controller commands the end effector component to move from the first position toward the second position.
