Embodiment 1

[0032] Such as figure 1 As shown, a fusion treatment device for high-intensity focused ultrasound-puncture ablation includes a disc-shaped focused ultrasound transmitter 1, and an electro-acoustic converter 10 is connected to it inside, and the electro-acoustic converter The controller 10 is connected with an external control auxiliary device 11.

[0033] The center of the focused ultrasound transmitter 1 is integrated with a video ultrasound probe 2 for displaying the patient's lesion and surrounding body tissues and a puncture ablation component 3. The puncture ablation component 3 in this embodiment is an example of the radio frequency ablation component 3.1 , which is provided with a through hole 9 at the center of the video ultrasonic probe, and a conduit 4 is provided inside the through hole 9, a base 5 is provided at the end of the conduit 4, and a conduit 4 is also provided with a The base 5 is fixedly connected with the radio frequency electrode 6 . The bottom of th...

Embodiment 2

[0036] Such as figure 2 As shown, embodiment 2 is a modification of embodiment 1, and its basic structure is consistent with embodiment 1, the difference is that the catheter 4 in this embodiment is rotatably connected to the side of the focused ultrasound transmitter 1 close to the image guiding device 2 position, so that the catheter 4 can rotate along the central axis of the imaging guide device 2, so that the radiofrequency ablation assembly 3 connected to the catheter 4, such as the radiofrequency electrode 6, can also rotate accordingly to meet the needs of different puncture angles and depths.

[0037]It can be understood that Embodiment 1 and Embodiment 2 use the radiofrequency ablation component 3.1 as an example for the puncture ablation component 3, and in other embodiments, the puncture ablation component 3 can also be replaced by microwave ablation, cryoablation, Combination of one or more of laser or electroporation techniques, the structure of which is basicall...

Abstract

The invention relates to the field of medical apparatus and instruments, and especially relates to high-intensity focused ultrasound-puncture ablation fusion therapy equipment. The therapy equipment includes a focused ultrasound transmitter capable of emitting focused ultrasound; and an image guiding device for displaying the focus and surrounding body tissue of patients and a set of puncture ablation assemblies are integrally arranged on the focused ultrasound transmitter. Thus, the defects in the prior art that are hardly overcome during the independent using of focused ultrasound and radiofrequency ablation can be overcome; through the fusion of focused ultrasound and radiofrequency ablation, mutual complement functions can be achieved, so that treatment quality can be guaranteed whiletreatment time is shortened; the therapy equipment is accurate and conformal, and can perfectly protect normal tissue and expand treatment indications while thorough treatment is guaranteed; and a novel method of thorough, fast, safe and minimally invasive treatment can be provided for tumor patients of which diseases are hard to treat or even cannot be treated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a high-intensity focused ultrasound-puncture ablation fusion therapy device. Background technique [0002] Focused ultrasound to treat tumors is to use ultrasonic waves to focus in the body, and generate high temperature and high pressure at the focal point to coagulate and necrosis the tumor. It has the advantages of non-invasive, precise, and conformal to the treatment range. [0003] For example, the application number is CN201610788078.3, a focused ultrasound treatment system, the focused ultrasound treatment system includes a treatment head, and the focused ultrasound treatment system also includes: an input module, the input module is used to input a reference ultrasound irradiation value, and Input a safety factor corresponding to the reference ultrasound exposure value; a calculation module, the calculation module is used to calculate a safe ultrasound exposure value based...
