Bubble-jetting member, gas-liquid jetting member, localized ablation device, and localized injection device

A gas/liquid jetting member, comprising a bubble-jetting member, and an outside shell part:

• wherein
• the bubble-jetting member comprises:
• a core formed of a conductive material and having a tip;
• a shell part formed of an insulating material, including an extended section extending beyond the tip of the core, and adheres at least partially to the core and covers the core, the extended section of the shell part having a tip including a bubble-jetting port;
• and
• a space formed between the extended section of the shell part and the tip of the core, and configured to receive a solution;
• the tip of the extended section of the shell part has a thick portion that is thicker than the rest of the extended section,
• the outside shell part at least partially encloses the shell part covering the core, the outside shell part having a tip section, the outside shell part and the shell part are spaced apart forming a space therebetween,
• an end of the outside shell part is connected to the bubble-jetting member by an expansion/contraction member, and
• the outside shell part and the bubble-jetting member are configured to be moveable relative to one another by the expansion/contraction member.
