Bubble ejection member and manufacturing method thereof, gas-liquid ejection member and manufacturing method thereof, local ablation device and local ablation method, injection device and injection method

Abstract

The present invention provides a device that can be processed locally without being damaged by heat when processing objects such as cells, and can be easily recombined or regenerated after processing, and can introduce injection substances efficiently , and a device for generating bubbles containing plasma. The object to be processed can be processed locally without damage by the local ablation device using a bubble ejection member including: a core material formed of a conductive material; an outer shell, formed of an insulating material, covering the core material, and including a portion extending from a front end of the core material; and a gap formed between the extending portion of the outer profile portion and the front end of the core material between. In addition, by further providing the outer contour portion on the outer periphery of the contour portion, the air bubbles adsorbed by the solution containing the injection substance can be released, and the injection substance can be introduced while performing local ablation of the object to be processed. In addition, it includes a pair of electrodes, which are formed of a conductive material, and are used to generate plasma in an inert gas; a liquid flow path for making a liquid flow; Gas and liquid containing bubbles of inert gas containing plasma flow; the liquid flow path and the fine flow path are connected downstream of the plasma-generating portion of the fine flow path to generate plasma-containing Because the bubbles of the body can maintain the plasma state even in the liquid, the plasma can be used to treat biological tissues.

AI Technical Summary

Problems solved by technology

However, in the conventional plasma technology, it is difficult to make a plasma-generating state exist in the solution, so it is used to generate plasma in the gas near the electrode at one time, and then use the generated plasma to generate plasma containing plasma in the solution. However, it is impossible to maintain the plasma state for a long time, and it is also difficult to move the bubbles while maintaining the plasma state (problem 10, refer to non-patent documents 5 and 6).
