Puncture-type endoscopic probe
First Claim
1. A puncture-type endoscopic probe which is inserted into the tissue using an endoscope in order to carry out the observation of the same, comprising:
- a fiber bundle composed of a plurality of optical fiber strands each having a light-emitting end which functions as a point light source;
an object optical system composed of imaging objective lenses which is used to focus the light beams emitted from the respective light-emitting ends onto a suspected surface position and a light beam deflection member used to deflect light beams which is positioned between the light-emitting ends and the suspected surface position; and
a puncture section located at the tip of the probe.

Abstract
This puncture-type endoscopic probe of the invention comprises: an object optical system consisting of a fiber bundle which is composed of a plurality of optical fiber strands each having a light-emitting end which functions as a point light source, an imaging objective lens which focuses the light beams emitted from the light-emitting ends onto the suspected surface position and a light beam deflection member (prism) for deflecting light which is positioned between the light-emitting ends and the suspected surface position; and a puncturing section which is attached to the tip of the probe. The imaging objective lens is constituted by a micro lens array, which is positioned so that the light-emitting end positions and the suspected surface position are conjugated each other. The object optical system can be rotated around the rotational axis defined by the puncture direction.
