Patent attributes
A laser induced liquid jet generating device comprising: a main body 6 adapted to be filled with a specified laser beam absorbing liquid and configured such that it can contain a laser irradiating part 4 of 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 body 6 to the outside; said main body 6 comprising: a catheter mounting unit mounted integrally or in a removable manner on a catheter member 13 into which said jet stream J is introduced; a jet generating tube unit 10 in which said laser irradiation part 4 is adapted to be positioned; and a heat transfer inhibition means 11 for inhibiting thermal effect due to laser beams irradiated by said laser irradiating part 4 from being transferred outside through said jet generating tube unit 10. 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.
