摘要： A suction head for a vacuum-actuated surgical grasper includes a proximal portion, a distal portion extending from the proximal portion, the distal portion being flared so as to have an outer dimension that increases from a proximal end of the distal portion to a distal end of the distal portion, and an inner passage extending through the suction head, the inner passage including a proximal portion that extends through the proximal portion of the suction head and a distal portion that extends through the distal portion of the suction head, wherein the distal portion of the inner passage is also flared so as to have an inner dimension that increases from the proximal end of the distal portion of the suction head to the distal end of the distal portion of the suction head, wherein the distal portion of the inner passage also includes internal ribs configured to grip tissue.

摘要： In one embodiment, a vacuum-actuated surgical grasper includes a suction head adapted to interface with patient tissue, a suction tube connected to and in fluid communication with the suction head, and a handle connected to the suction tube, the handle comprising an internal passage in fluid communication with the suction tube through which fluid from the suction tube can flow and a pivotable actuation lever that controls this flow through the passage.
