摘要： Various example embodiments are directed towards a system and method for closed feedback control of a robotically controlled electrosurgical instrument. In one embodiment, the method comprises applying at least one electrosurgical signal to an electrosurgical end effector a robotically controlled surgical instrument. A feedback signal may be generated by the electrosurgical end effector and provided to a control logic. The control logic may be configured to determine a rate of change of the impedance of a target tissue based on the feedback signal received from the electrosurgical end effector. The control logic may be configured to control or modify the at least one electrosurgical signal such that the rate of change of impedance determined from the feedback signal is maintained at a predetermined rate or within a predetermined range.

摘要： A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i.e., staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A traction biased firing mechanism avoids binding in driving this straightened linked rack. The instrument further has a manually actuatable retraction system that does not require the use of additional springs or other mechanisms to generate retraction forces which must be overcome when generating the forces necessary to fire the device. In various embodiments, the retraction system provides a visual indication to the surgeon as to how far firing has progressed.

摘要： A surgical instrument particularly suited to endoscopic and laparoscopic insertion through a cannula of a trocar into an insufflated body cavity or lumen includes a bending member in an elongate shaft that acts to rotate an end effector about an articulation pivot joint. A proximally directed camming surface (e.g., gear segment, cam recess) aft of a pivotal attachment of the end effector to a proximal frame ground of the elongate shaft interacts with a bending member whose proximal end is ground to the proximal frame ground. Differential fluidic actuators or mechanical cam bars deflect a distal end (e.g., rack, cam point) of the bending member to effect articulation. Thereby, the end effector may act upon tissue that would otherwise be obscured, such as behind an organ. The articulated end effector also advantageously allows an endoscope to be positioned behind the end effector without being blocked by the instrument shaft.

摘要： A surgical instrument including a firing drive configured to advance a cutting member and/or staple driver within an end effector, and a brake configured to prevent, or at least partially inhibit, the relative movement of the cutting member and/or staple driver. The surgical instrument can further include a firing member operably engaged with the cutting member, for example, a band connected to the firing member, and a reel, where the band can be configured to be wound around the reel. In various embodiments, the brake can be selectively engageable with the reel and/or band to prevent, or limit, the movement of the band. The brake can include a brake surface where relative movement between the band and the brake surface can generate a friction force therebetween which can hold the firing member in position until a sufficient force is applied to the firing member to overcome the friction force.
