摘要： Ultrasonic surgical instruments including a handle housing, a switch frame, and a switch assembly are disclosed. The switch assembly may include a first switch arrangement movably supported on a distal portion of the handle housing and selectively movable relative to a first switch contact supported by the switch frame. The switch assembly may further include a second switch arrangement including a right switch button movably supported on a right side of the handle housing and selectively movable relative to a right switch contact supported by the switch frame, and a left switch button movably supported on a left side of the handle housing and selectively movable relative to a left switch contact supported by the switch frame. The first and second switch arrangements may be configured to be selectively actuatable by a single hand supporting the handle housing.

摘要： Aspects of the present disclosure are presented for a surgical instrument for cutting and sealing tissue. In some embodiments, the surgical instrument includes a handle assembly, a shaft, and an end effector. The end effector may include: a blade that vibrates at an ultrasonic frequency, a shielded portion enclosing a back edge of the blade, a high-friction surface coupled to the shielded portion and positioned between the shielded portion and the back edge of the blade. A space is defined between the high-friction surface and the back edge of the blade when the end effector is in a cutting configuration. In a sealing configuration, the high-friction surface contacts the back edge of the blade, which generates heat based on ultrasonic vibrations of the blade rubbing against the high-friction surface. The shielded portion can coagulate bleeding tissue based on heat transfer from the high-friction surface to the shielded portion.
