## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The surgical system according to claim 1, wherein, in the imaging orientation, each ultrasound sensor of the plurality of ultrasound sensors is configured to emit an ultrasound wave, receive an echoed wave, and output the echoes wave to be reconstructed to produce a real-time 3D ultrasound video image.

### Claim 3 (depends on 1)

The surgical system according to claim 1, wherein, in the treatment orientation, the ultrasound sensors are configured to emit ultrasound waves towards the common focus point to ablate tissue at the common focus point.

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.

### Claim 10 (depends on 9)
