High-strength focusing ultrasonic therapy system introduced by image equipment

Abstract

The invention discloses a high-strength focusing therapeutic system guided by image equipment, which comprises the following parts: ultrasonic therapeutic head with ultrasonic transducer, therapeutic bed to place the patient and image equipment to image the focus, wherein the image equipment adopts two-dimension imaging non-ultrasonic image equipment; the focal core diameter in the biological focal area is 0. 1-5mm to focus through ultrasonic transducer, which optimizes the focal core diameter at 0. 2-2mm; the non-ultrasonic image equipment adopts CT set or MRI equipment with two-dimensional imaging function. The invention images the target precisely to do precise treatment for complex surgery, which has good therapeutic effect.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an ultrasonic treatment system, in particular to a high-intensity focused ultrasonic treatment system guided by imaging equipment. Background technique [0002] In the field of ultrasonic therapy, when ultrasonic thermotherapy is used for treatment, due to technical and cognitive reasons, people do not know much about the mechanism of focus in vivo, and hope to achieve the purpose of rapid treatment through multi-focus. However, the therapeutic effect achieved by using this multi-focus ultrasonic therapeutic equipment is not ideal. At the same time, with the development of ultrasound technology, especially high-intensity focused ultrasound is now widely used in treatment, what people need is a kind of fine surgical treatment equipment, because only these equipment can treat certain diseases (especially Malignant tumors) undergo complete treatment or resection.

Problems solved by technology

[0006] U.S. Patent No. 5,485,839 discloses a treatment system combining an MRI device and an ultrasonic treatment device. The patent points out that tumors and other tissues to be treated usually have a relatively complex three-dimensional shape, and it is difficult to achieve comprehensive treatment by using two-dimensional ultrasonic tomographic images alone. For the complete treatment and curative effect evaluation of tumors, a technical scheme of using MRI three-dimensional tomographic images to image the target body before and after treatment and using two-dimensional ultrasound to monitor the treatment process in real time

[0007] The above-mentioned patent uses MRI to create three-dimensional images of the target body before and after treatment, and displays the constructed three-dimensional shape of the target body on the monitor. In this way, the reconstructed 3D image is unreal and cannot fully reflect the original shape of the tumor. Treatment according to this distorted image will inevitably lead to incomplete treatment.

For malignant tumors, these residual lesions will continue to expand, which will again bring danger to the patient's life, so the technical solution of the above patent cannot complete accurate ultrasound treatment

And in this patent, if the MRI equipment is not modified, it is necessary to repeatedly move the patient into and out of the aperture of the MRI, which prolongs the treatment time; and if the patient does not want to be moved, the structure of the MRI must be modified. will increase the cost of treatment
