Embodiment 1

[0045] In order to describe the technical solution more clearly, the "target nerve" and "target area" are defined in the following scheme. Target area: the specific body tissue containing the "target nerve", such as: in the treatment of hypertension, the target The area refers to the tissue around the renal artery containing the renal sympathetic nerve, and the target nerve refers to the renal sympathetic nerve. Another example: in the pain relief treatment of cancer pain, the target area refers to the deep part containing the abdominal cavity and visceral ganglion tissue, the target nerve refers to the celiac ganglion.

[0075] Example 2 Dual Mapping System Mapping of Celiac Plexus-Ablation Treatment of Cancer Pain

[0076] The incidence of pain caused by tumors is as high as 80% in patients with advanced tumors. Although there are many pathogenesis of pain, the analgesic effect of "damaged celiac plexus block (NCPB)" is over 90%, and there is no clear effect on anti-tumor therapy. It is of value in advanced cancer patients with limited expected survival. Ablation of the celiac ganglion using HIFU has been gradually applied in clinical practice, and has achieved certain therapeutic effects. However, the celiac plexus is deeply buried inside the body, and relying on ultrasound image guidance has the problems of insufficient positioning and damage to surrounding adjacent tissues; in addition, currently There is a lack of methods for evaluating the function of celiac nerves, and it is impossible to immediately evaluate the state of nerve function after ablation.

Abstract

The invention relates to a dual-mapping system integrating detection and ablation. The dual-mapping system includes a difference-frequency focused ultrasonic transducer and a dual-frequency ultrasonic signal generator; the difference-frequency focused ultrasonic transducer emits two The ultrasonic beams of different frequencies are confocal, and the wave interference effect is generated at the focal point to generate the difference frequency vibration sound. The dual mapping system also includes a physical mapping system and a physiological mapping system; the physical mapping system obtains the detection surface of the target nerve position through the low-frequency vibration amplitude; the physiological mapping system detects the position of the target nerve through physical stimulation. The treatment target on the detection surface, and the physical mapping system first quickly maps to find the position or relative position of the detection surface where the target nerve is located, and then performs precise mapping on the detection surface through the physiological mapping system. Its advantages are as follows: it can be applied to the internal tissues of the human body, quickly obtain the detection surface, and then accurately stimulate the target nerve through the detection surface to achieve the purpose of fast and accurate treatment.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a dual mapping system integrating detection and ablation. Background technique [0002] In recent years, with the development of non-invasive ultrasound systems, it is currently the mainstream research direction to use ultrasound systems to generate mechanical stimulation to nerves, and to detect the response of nerve activity through mechanical stimulation, and then to find the target of disease treatment. [0003] However, the detection of the ultrasonic system uses high-frequency ultrasound for detection. Research has found that although the detection of high-frequency ultrasound in the prior art has good conduction directionality, it can form a fine focus. However, due to the extremely fast vibration frequency and small amplitude, the mechanical effect is weak and appears as a thermal effect. When deep stimulation is required, short pulses are often implemented at di...
