Problems solved by technology
[0006] Since the treatment temperature of the lesion cannot be changed by turning off some transducer slices, the energy of the turned off transducer slices needs to be evenly distributed to the rest of the transducer slices, which increases the cost of each transducer slice. The burden of its drive circuit increases the requirements for a separate transducer sheet and drive circuit
[0007] Not only that, due to the uncertain number of covered transducer sheets, in order to ensure that sufficient energy can be output, redundancy must be reserved for the energy that can be emitted by the transducer sheet and its drive circuit, which undoubtedly further improves the reliability of the sensor. The requirements of the transducer chip and its driving circuit pose greater challenges to the safety and risk of the system

Embodiment Construction
[0043] The transducer device for high-intensity focused ultrasound of the present invention will be described in detail below with reference to the accompanying drawings.
[0044] Such as figure 1 As shown, a transducer device for high-intensity focused ultrasound includes: a bracket (not shown in the figure), a base 7 rotatably mounted on the bracket, an arc-shaped guide rail 2 fixed on the base 7, and an arc-shaped The guide rail 2 is slidingly fitted with an arc-shaped support 1 , several transducer pieces installed on the arc-shaped support 1 , and a locking mechanism for fixing the relative positions of the arc-shaped support 1 and the arc-shaped guide rail 2 .
[0045] In order to ensure the intensity of the focused ultrasound, multiple arc supports 1 can be matched on the arc guide rail 2 at the same time, and each arc support 1 is arranged side by side, and the acoustic paths of the transducer sheets on all arc supports 1 are focused on the same a little.

The invention discloses a transduction device for high-intensity focused ultrasound. The transduction device comprises a base, an arc-shaped guide rail, an arc-shaped support and a locking mechanism, wherein the arc-shaped guide rail is fixed on the base, the arc-shaped support is slidably matched with the arc-shaped guide rail, a plurality of transducer devices are mounted on the arc-shaped support, focuses of the transducer devices and the circular center of the arc-shaped guide rail are arranged on the same point, and the locking mechanism is used for fixing the relative position of the arc-shaped support and the arc-shaped guide rail. Sound path of the transducer devices is prevented from blocking by mechanical motion, and high-intensity focused ultrasound treatment can be performed under the condition that the transducer devices are not turned off.
Description
technical field [0001] The invention relates to the technical field of high-intensity focused ultrasound, in particular to a transducer device for high-intensity focused ultrasound. Background technique [0002] As a new local treatment method, high-intensity focused ultrasound therapy is more and more popular in the treatment of tumor diseases that require non-invasive and organ function preservation due to its non-invasive, effective, safe, fast recovery after treatment, and no radiation damage. The more attention it receives, the brighter the prospect of application, clinical application and research are in the ascendant. [0003] However, since many organs of the human body are deeply located in the body, the ultrasonic waves will inevitably be blocked during the ultrasonic treatment process. If the treatment is performed forcibly, the damage to the healthy parts cannot be avoided, and the energy and therapeutic effect of the ultrasonic waves will be greatly reduced. . ...
