Embodiment 1

[0058] Such as figure 2 As shown, in an embodiment of the present application, the second shape is a cylinder or an elliptical cylinder. At least one end surface of the cylinder or elliptical cylinder is a concave spherical surface. The focusing transducer 120 has a groove 121 .

[0059] The shape of the image transducer 110 is a cylinder or an ellipse cylinder. The image transducer 110 is embedded in the groove 121 . The center of the end face of the image transducer 110 coincides with the physical center of the end face of the focusing transducer 120 .

[0060] Specifically, in Embodiment 1, the second shape of the focusing transducer 120 is a cylinder or an elliptical cylinder, that is, the focusing transducer 120 is in a shape after the lumen of the object to be treated is expanded. The difference is that when the second shape is a cylinder, the two end surfaces are circular. When the second shape is an elliptical cylinder, the two end faces are elliptical. At least...

Embodiment 1-1

[0064] Such as image 3 and Figure 4 As shown, in an embodiment of the present application, the focusing transducer 120 includes two first transducer modules 122 . When the second shape is a cylinder, the shape of the first transducer module 122 is a semi-cylindrical formed after the cylinder in the second shape is separated by an axial section. When the second shape is an elliptical cylinder, the shape of the first transducer module 122 is a semi-elliptical cylinder formed by dividing the elliptical cylinder presented by the second shape with an axial section. The first transducer module 122 has a recess 122a.

[0065] When the high-intensity focused ultrasound device 10 is in the first state, the two first transducer modules 122 are folded to form the focusing transducer 120 in the first shape. The first shape is a half cylinder formed by folding two half cylinders or a half ellipse cylinder formed by folding two half ellipse cylinders. The first state is that the high-...

Embodiment 1-2

[0071] Such as Figure 5 and Figure 6 As shown, in an embodiment of the present application, the focusing transducer 120 includes a second transducer module 123 and two third transducer modules 124 . The two third transducer modules 124 are respectively disposed on two sides of the second transducer module 123 . The two third transducer modules 124 are movably connected to the second transducer module 123 respectively. The groove 121 is disposed on the second transducer module 123 .

[0072] When the high-intensity focused ultrasound device 10 is in the first state, the two third transducer modules 124 are folded to form the focusing transducer 120 in the first shape. The first state is that the high-intensity focused ultrasound device 10 is outside the object to be treated. The first shape is the shape of the second transducer module 123 .

[0073] When the high-intensity focused ultrasound device 10 is in the second state, the two third transducer modules 124 are unfol...

Abstract

The invention relates to high-intensity focused ultrasound equipment and a control method, wherein the high-intensity focused ultrasound equipment is used for focusing ultrasonic waves; the focusing transducer with the shape capable of being freely changed is arranged; the whole transducer assembly extends into the inner cavity of the to-be-treated object; the transducer assembly can extend into an inner cavity of a to-be-treated object through a narrow part; after the ultrasonic transducer assembly extends into the inner cavity of the to-be-processed object, the shape of the focusing transducer in the transducer assembly is changed, the effective area of the focusing transducer is increased, the generated ultrasonic energy is increased, the irradiation intensity of the to-be-processed area is enhanced, and the normal working requirement of the transducer assembly is met.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a high-intensity focused ultrasound device and a control method. Background technique [0002] High-Intensity Focused Ultrasound (HIFU for short) has become a hot research field in the field of ultrasonic treatment in recent years due to its non-invasive and strong focusing characteristics. At present, there are two mechanisms of action of high-intensity focused ultrasound: thermal ablation mechanism and tissue damage mechanism. The thermal ablation mechanism mainly utilizes the thermal effect of ultrasound to focus the ultrasound energy to the target area to form local high-intensity ultrasound energy to ablate the target area tissue, so that the target area tissue is instantly placed in a high temperature environment, resulting in coagulation necrosis. Histotripsy mode mainly utilizes the cavitation mechanical effect of HIFU to crush target tissue into micron...
