Problems solved by technology

However, according to this structure, there is a certain disadvantage: when the OCT probe is made to protrude from the forceps opening of this endoscope equipped with an inflatable bag, the distance between the OCT probe and the wall is too large
[0014] In this case, for example, the elongated OCT probe 3 protruding from the distal opening 2 is not rigid enough because the sheath of the OCT probe 3 is flexible
Therefore, because the OCT probe protruding portion is easily bent in a manner in which the distal opening 2 serves as a fulcrum, and furthermore, due to a folded structure of tissue inside a body cavity or a flutter movement or the like, it is difficult to maintain the sheath of the OCT probe 3 therein. While the outer surface of the OCT probe 3 is in contact with the surface of the measurement object S, or with respect to the above state, the outer surface of the sheath 5 of the OCT probe 3 is held at a position where the OCT probe 3 is further spaced from the surface of the measurement object S observe at the same time

Abstract

Provided is an optical probe (600) including: a cylindrical sheath (622) having a closed end; a light guiding means (623) arranged inside the sheath along the longitudinal axis of the sheath; and a light collection means (628) which is arranged at the emission end side of the light guiding means so as to deflect the optical path of the light emitted from the emission end so that the light is converged on a measured object. The optical probe (600) scans the converged light on the plane substantially orthogonally intersecting the optical axis of the converged light emitted from the light collection means (628) and guides the light from the measured object (S) via the light collection means to the light guiding means (623). A cylindrical tube member (610) having an external circumferential wall integrally connected to the external wall of the sheath (622) is arranged along the aforementioned longitudinal axis direction of the sheath (622).

Description

technical field [0001] The present invention relates to an optical probe and an optical observation device, and more particularly, to an optical probe and an optical observation device, characterized by a sheath structure of the optical probe. Background technique [0002] Conventionally, as an endoscope device for observing the inside of a body cavity of a living body, an electronic endoscope device emitting illumination light inside the body cavity of a living body collects an image using reflected light and displays the image on a monitor or the like, The electronic endoscope apparatus is widely used and used in various fields. Most endoscopic devices are equipped with a forceps opening and biopsy or treatment of tissue within a body cavity can be performed by means of a probe introduced into the body cavity through the forceps opening. [0003] Meanwhile, development of a tomographic image acquisition apparatus as an optical observation device that acquires a tomographi...
