Abstract: Provided are a device whereby, during process of a process target such as a cell or the like, localized process of a process part is possible without inflicting damage due to heat, and rejoining and regeneration may proceed readily subsequent to process, and whereby an injection substance may be introduced efficiently; and a device for generating bubbles containing a plasma. Through the use of a localized ablation device employing a bubble jetting member having a core formed from a conductive material, a shell part formed from an insulating material, covering the core and including a section extending from the tip of the core, and a space formed between the extended section of the shell part and the tip of the core, a process target can be treated in localized fashion and without inflicting damage.

Abstract: An endoscopic surgical device includes: a sheath; a forceps section protruding from a cover provided at a distal end of the sheath and including a pair of openable-closable forceps components; an operable member that is connected to a proximal end of the forceps section, that opens the forceps components when moved forward in a longitudinal direction, and that closes the forceps components when moved rearward; and a flow-path formation member having a through-hole through which the operable member extends and having a first liquid delivery hole constituted by a gap between the through-hole and the operable member and a second liquid delivery hole constituted by a gap between the flow-path formation member and an inner peripheral surface of the cover. The operable member is provided with a large-diameter section that abuts on the flow-path formation member when the operable member is moved forward to block the first liquid delivery hole.

Abstract: Provided is an endoscopic surgical device includes: a sheath having a pipe for delivering a liquid and inserted into a channel of an endoscope; a pair of forceps components disposed so as to protrude from a distal end cover of the sheath; an operable member that is connected to the forceps components and opens and closes the forceps components; and a flow-path formation member positioned at proximal end side rather than the forceps components and is disposed in a rotatable manner about a central axis of the sheath together with the forceps components. The flow-path formation member includes a recess disposed in a direction orthogonal to an opening-closing direction of the forceps components and recessed radially inward. The recess forms a gap between the flow-path formation member and an inner peripheral surface of the distal end cover so as to constitute a liquid delivery hole.

Abstract: Provided are a protein crystal device and method for crystallizing protein capable of generating protein crystal without imparting a heat effect, a protein crystal-cutting device and method for cutting protein crystal capable of cutting protein crystal without imparting a heat effect on protein crystal, and bubble-jetting member and protein-adsorbing-bubble-jetting member used in said device. A bubble-jetting member is used in a protein crystal device to jet bubbles into a protein solution to thereby allow protein crystals to be obtained, the bubble-jetting member comprising: a core formed of a conductive material; a shell part formed of an insulating material, including an extended section extending from the tip of the core, and in which at least a portion closely adheres to the core to cover the core; and a gap having a bubble-jetting port, the gap being formed between the extended section and the tip of the core.
