Abstract: Provided are a high-intensity focused ultrasound apparatus (10) and a control method. According to the high-intensity focused ultrasound apparatus (10), by providing a focusing transducer (120) having a freely transformable shape, after an entire transducer assembly (100) extends into an inner cavity of an object to be treated, the transducer assembly (100) can extend through a narrow part into the inner cavity of an object to be treated, and after extending into the inner cavity of the object to be treated, the shape of the focusing transducer (120) in the transducer assembly (100) changes, so that the effective area of the focusing transducer (120) increases, and the ultrasonic energy produced increases, thereby enhancing the irradiation intensity for a region to be treated, and satisfying normal operation requirements of the transducer assembly (100).

Abstract: Provided is an ultrasonographic device. The ultrasonographic device includes a mounting housing, an ultrasonic transducer, and a puncture support. The ultrasonic transducer is rotatably disposed in an inner cavity of the mounting housing and spaced apart from the mounting housing. The puncture support is provided on an outer side of the mounting housing, where a puncture guide hole through which a puncture needle penetrates is provided on the puncture support, and the puncture support is capable of rotating synchronously with the ultrasonic transducer so that an axis of the puncture guide hole is coplanar with a real-time scanning plane of the ultrasonic transducer.

Abstract: According to a high-intensity focused ultrasonic apparatus and a control method, an image of a region to be treated is obtained by means of an imaging device, a working assembly and a target coordinate point in the region to be treated are located by means of an optical tracking device, so that a positioning device can clamp the working assembly to quickly and accurately move to a working position corresponding to the target coordinate point, thereby enabling the working assembly to quickly and accurately release a high-intensity focused ultrasonic pulse to the target coordinate point, which improves not only the treatment accuracy but also the treatment efficiency of the high-intensity focused ultrasonic apparatus.

Abstract: The invention relates to a monitoring system for monitoring at least one device. The monitoring system comprises a magnification lens system to generate a magnified image of the at least one device, and at least three positional sensors in an arrangement around the magnification lens system to determine a position of the at least one device. The at least one device may be a surgical tool.
