Problems solved by technology

The disadvantage is that the focused ultrasonic transducer moves three-dimensionally in the treatment head, increasing the movement dimension and increasing the weight of the mechanical structure; the diameter of the treatment head needs to increase the movement distance, the outer diameter of the treatment head increases, and at the same time, the coupling water consumption is doubled, requiring products Increased mechanical size and scale
In addition, the diameter of the treatment head becomes larger and the weight becomes heavier, which will also affect the application range of HIFU treatment

Embodiment 1

[0029] See figure 1 , a method for using an ultrasonic spherical surface scanning three-dimensional body treatment device. The HIFU treatment head can form an ablation of any shape in a three-dimensional curved surface cylinder by controlling the rocking angle α of the mechanism, the rotation angle β of the rotating mechanism, and the Z parameter of the moving position of the lifting mechanism. body.

[0030] The rotation angle β of the rotating mechanism 3 remains unchanged, and the rocking mechanism 2 makes the ultrasonic focusing transducer 1 tilt at an angle α around the rotation axis of the rocking mechanism 2. When in use, the ultrasonic focusing transducer 1 produces tissue ablation at the focal position of its acoustic axis lesion; if the rocking mechanism 2 changes the inclination angle α, the ultrasonic focusing transducer 1 will form another ablation lesion at the curve position whose radius R is the vertical distance from the center of the rotation axis of the rock...

Embodiment 2

[0032]The rocking mechanism 3 tilts the focusing transducer with the rotation axis of the rocking mechanism at an angle of α, and the rotating mechanism 3 changes the rotation angle β, which will be centered at the focal point with the tilt angle as 0, and the curve radius R and the tilt angle α are sinusoidal Another ablation lesion is formed at the position of the circle whose product is the radius r; the continuous and orderly change of the rotation angle β is about 0-360°.

Embodiment 3

[0034] On the basis of Example 2, after the tissue ablation ring is formed, the center inclination angle α of the rocking mechanism 2 is changed, and then the treatment of the above ring of ablation lesion is performed to form another ring of ablation lesion; the swing angle α of the rocking mechanism 2 is continuously changed , continue to use the ring of HIFU tissue ablation lesion, will form a curved surface of HIFU ablation lesion or a curved surface with a central hole; the maximum diameter of the ablation lesion surface is equal to the sine product value of the radius R of the curve and the maximum inclination angle α.

Abstract

The invention relates to a three-dimensional body treatment device having a function of ultrasonic spherical surface scanning. The three-dimensional body treatment device comprises an ultrasonic focused transducer, wherein a position finding probe lifting device and a position finding probe rotating device are mounted at a center hole of the ultrasonic focused transducer. The three-dimensional body treatment device is characterized in that a swinging mechanism, a rotating mechanism and a lifting mechanism are sequentially in series connection to the upper end of the ultrasonic focused transducer; the lower end of the swinging mechanism is hinged to the ultrasonic focused transducer through a swinging rotating shaft, and the upper end of the swinging mechanism is fixedly connected with a rotating disk of the rotating mechanism; the rotating mechanism is connected with the free end of the lifting mechanism; and an HIFU treatment head is formed by the ultrasonic focused transducer, the swinging mechanism, the rotating mechanism, the lifting mechanism, the position finding probe lifting device, the position finding probe rotating device and a water tank or a water sac for accommodatingcoupling water. According to the three-dimensional body treatment mechanical structure having the function of ultrasonic spherical surface scanning disclosed by the invention, the treatment head is small in diameter and light in weight; and during treatment, moving the three-dimensional body treatment mechanical structure is not needed, the defects of a conventional mechanical structure are overcome, and the treatment requirements of performing thermal ablation on a three-dimensional scanning body in an arbitrary shape in the treatment range are completed.

Description

technical field [0001] The invention relates to an ultrasonic treatment device, in particular to an ultrasonic spherical surface scanning three-dimensional body treatment device and a method for using the same, belonging to the technical field of medical equipment. Background technique [0002] High Intensity Focused Ultrasound (HIFU) is a new non-invasive treatment method, which has the advantages of no wound, no infection, short recovery period and good curative effect. Since Lynn et al. first reported HIFU treatment in 1942, at present, many HIFU products at home and abroad have completed the registration of medical device products and are used in clinical practice. The principle of HIFU is to use low-megahertz frequency bands with beam radiation and good penetrating ability in human tissue, and to form an energy-dense three-dimensional area in the medium around the focus through convergence technology—the focal area. When the propagation medium is human tissue, the tiss...
