<P>PROBLEM TO BE SOLVED: To reduce to suck a not-excised biological tissue to be damaged, while securing a required suction amount, when sucking a liquid jetted from a jetting port, a blood staying in an operation part, and an excised biological tissue. <P>SOLUTION: The biological tissue of the operation part is excised by pressure of the liquid jetted from the jetting port in a form of a pulsation flow. The liquid or the like staying in the operation part is sucked with the jetting in the form of a pulsation flow, by a suction means. Suction negative pressure can be varied periodically when sucking the liquid of the operation part by the suction means. A condition for sucking the liquid is changeable variously thereby, and consequently, the liquid is sucked under a proper condition with no risk of sucking the biological tissue, as a result thereof, while securing the required suction amount. <P>COPYRIGHT: (C)2011,JPO&INPIT |
