<P>PROBLEM TO BE SOLVED: To provide a fluid injection device capable of switching a resection fluid and a contrast agent to be injected. <P>SOLUTION: The fluid injection device 1 includes: one fluid injection part 40 for injecting either the resection fluid or contrast agent; a pump 20 as a fluid feeding means for feeding the resection fluid or contrast agent to the fluid injection part 40: a catheter 6 for connecting the fluid injection part 40 to the pump 20; and valves 31 and 32 as switching means for switching the fluid to be injected either to the resection fluid or to the contrast agent. When an object to be resected within capillary tissue confirmed by imaging is resected, the fluid to be fed is switched from the contrast agent to the resection fluid for resection. When the state of the capillary tissue after resection is confirmed, the fluid can be switched from the resection fluid to the contrast agent. In this way, insertion/extraction of the catheter 6 is not necessary for each imaging or resection, and as a result, burdens both on a patient and on an operator can be significantly reduced. <P>COPYRIGHT: (C)2011,JPO&INPIT |
