Embodiment 1

[0048] Example 1, please refer to Figure 1 to Figure 3 , this embodiment provides a dual-modality tissue ablation needle, which cooperates with the host to realize dual-mode switching of pulsed electric field and radio frequency energy on a single needle body 1, so that the device can switch when facing tumors of different sizes Different modes in order to reduce the difficulty and risk of surgery.

[0049] The dual-modality tissue ablation needle includes a needle body 1, an insulating assembly 2 and a water delivery assembly 3. One end of the needle tip 11 of the needle body 1 will directly enter the tumor tissue through the user's operation, and the other end of the needle body 1 is connected to an external host, which is connected to the external host. The dual-mode switching of pulsed electric field and radio frequency energy can be realized by adjusting the output energy. The insulating component 2 is used to provide insulation protection for the needle body 1 when the ...

Abstract

This application is applicable to the technical field of ablation needles, and proposes a dual-mode tissue ablation needle, including a needle body, an insulating component, and a water delivery component; the insulating component is slidably sleeved outside the needle body; Water channel, one end of the water channel is connected to the water delivery component and the other end is connected to the outside world; the present invention has a simple structure, is easy to operate and use, and can perform dual-mode switching of pulsed electric field and radio frequency energy for different lesions and tumors of different sizes The use reduces the difficulty and risk of the operation, and has strong practicability.

Description

technical field [0001] The invention relates to the technical field of ablation needles, in particular to a bimodal tissue ablation needle. Background technique [0002] Under the background that minimally invasive treatment methods are gradually accepted by doctors and patients, various tissue ablation techniques are becoming important means in tumor treatment and other fields. Compared with radiofrequency, cryo and microwave ablation, pulsed electric field ablation is a new ablation method that uses high-voltage pulsed electric field as energy. balance, resulting in rapid cell apoptosis. At present, pulsed electric field ablation can be mainly used for the treatment of tumors and atrial fibrillation. When it is applied to ablate tumors, it can form nanoscale irreversible perforations in the cell membrane of tumor cells, so the technology is also called "nanoknife". [0003] Pulsed electric field ablation is generally used to puncture the lesion through an ablation needle...
