ABSTRACT:
A laser induced liquid jet generating device comprising: a main body6adapted to be filled with a specified laser beam absorbing liquid and configured such that it can contain a laser irradiating part4of an optical fiber from which laser beams are emitted to generate jet streams J of said liquid W by irradiating said liquid W with laser beams, with said jet streams J ejected from said main body6to the outside; said main body6comprising: a catheter mounting unit mounted integrally or in a removable manner on a catheter member13into which said jet stream J is introduced; a jet generating tube unit10in which said laser irradiation part4is adapted to be positioned; and a heat transfer inhibition means11for inhibiting thermal effect due to laser beams irradiated by said laser irradiating part4from being transferred outside through said jet generating tube unit10. Thus, it provides a laser induced liquid jet generating device that is safe for both the operator and the patient as it can apply irradiation of powerful laser beams for a long period of time without the catheter being thermally affected by the laser beams.
