Abstract
An abnormality detection system for highly precise detection of an abnormality in a laser treatment device includes a laser transmission tube coupled with a laser treatment unit, oscillating laser light, a discharge-side water pressure sensor, and a water pressure detection liquid surface level meter detecting a change in a pressure of cooling water flowing through forward-direction and a backward-direction spaces in the laser transmission tube. The laser transmission tube includes a hollow wavelength path having a lightguide space formed in a longitudinal direction, and an outer case enclosing an outer circumferential surface of the hollow waveguide path and extending in the longitudinal direction. The discharge-side water pressure sensor and the water pressure detection liquid surface level meter detect the change in the pressure of the cooling water flowing through in a forward-direction space and a backward-direction space to detect any abnormality.
