Computer aided image-based enhanced intracorporeal lithotripsy

摘要

An apparatus is configured to deliver destructive energy to a stone. The apparatus includes a detector operative to obtain image data from the stone, a generator operating according to one or more producing parameters for producing the destructive energy, and a video processor unit receiving the image data from the detector. The video processor unit is operative to analyze the image data to determine a displacement of the stone relative to a previous location of the stone. A controller linked to the video processor unit and to the generator is operative to vary the one or more producing parameters of the generator responsively to the displacement of the stone. Methods carried out by the apparatus are further provided.

1. A medical apparatus for preforming lithotripsy, comprising:
a device configured to deliver a destructive energy to a stone; a detector operative to obtain image data from the stone; a generator including one or more producing parameters for producing the destructive energy; a video processor unit, which is coupled to receive the image data from the detector and is operative to analyze the image data under control of software to establish a contour line of the stone and thereby to determine a displacement of the stone relative to a previous location of the stone responsively to an actuation of the device to deliver the destructive energy, and is programmed to issue an alert when the displacement exceeds a displacement threshold; and a controller linked to the video processor unit and to the generator, the controller operative to vary the one or more producing parameters of the generator in response to control signals from the video processor unit responsively to the displacement of the stone.
