Abstract
A surgical system includes a surgical instrument having a shaft and an end effector extending distally from the shaft. The end effector includes a plurality of ultrasound sensors supported about a support ring. The ultrasonic sensors are rotatable between an imaging orientation, wherein, the ultrasound sensors are directed in generally parallel orientations relative to one another for imaging tissue in an imaging mode, and at least one treatment orientation, wherein the ultrasound sensors are directed towards a common focus point for treating tissue in a treatment mode.
Claims13
A surgical system, comprising:
- a surgical instrument, including:
- a shaft;
- and
- an end effector extending distally from the shaft, the end effector including a pivot sleeve engaged with the shaft, the end effector including a plurality of ultrasound sensors supported about a support ring, the pivot sleeve arranged about a portion of the support ring to allow pivoting of the end effector with respect to the shaft, the ultrasonic sensors rotatable between an imaging orientation, wherein the ultrasound sensors are directed in parallel orientations relative to one another for imaging tissue in an imaging mode, and at least one treatment orientation, wherein the ultrasound sensors are directed towards a common focus point for treating tissue in a treatment mode,
- wherein each ultrasound sensor of the plurality of ultrasound sensors is supported by an outer ring of a plurality of outer rings rotatably disposed about the support ring, wherein each outer ring is rotatable relative to the support ring and relative to each other outer ring of the plurality of outer rings.

A method of surgery, comprising:
- inserting an end effector of a surgical instrument into an internal surgical site, the end effector including a plurality of ultrasound sensors supported about a support ring and a pivot sleeve arranged about a portion of the support ring, wherein each ultrasound sensor of the plurality of ultrasound sensors is supported by an outer ring of a plurality of outer rings rotatably disposed about the support ring;
- pivoting the end effector by rotating the support ring within the pivot sleeve;
- rotating the plurality of outer rings relative to one another to arrange the plurality of ultrasound sensors in an imaging orientation;
- activating, in an imaging mode, the plurality of ultrasound sensors of the end effector to produce a real-time 3D ultrasound video image of the internal surgical site;
- viewing the real-time 3D ultrasound video image on a visual display to identify a target tissue;
- rotating the plurality of outer rings relative to one another to arrange the plurality of ultrasound sensors in a treatment orientation;
- and
- activating, in a treatment mode, the plurality of ultrasound sensors of the end effector to ablate the target tissue.
