Endoscopic devices and medical systems

Abstract

The endoscope device of the present invention includes: a light source device that emits excitation light in a wavelength band including a first wavelength band and a second wavelength band, and the excitation light in the first wavelength band is used to excite the first fluorescent substance; Taking pictures of the first fluorescence emitted when the first fluorescent substance is excited and the second fluorescence emitted when the second fluorescent substance on the treatment instrument is excited to generate a fluorescence image; the information storage unit stores information related to the second fluorescence shape information, which is information on the shape of the substance; and a calculation unit that performs calculations for calculating the scaling factor based on the shape information and the size of the rendering area of ​​the second fluorescent light and the size of the rendering area of ​​the first fluorescent light, Estimate the actual size of the region where the 1st fluorescence is produced.

Description

technical field [0001] The present invention relates to an endoscope device and a medical system, and particularly to an endoscope device and a medical system capable of observing fluorescence emitted from a fluorescent substance in a living body. Background technique [0002] Conventionally, there are known diagnostic techniques using fluorescent agents that target living proteins specifically found in predetermined lesions such as cancer. Specifically, for example, conventionally known diagnostic techniques include irradiating excitation light to a subject part in a living body to which a fluorescent agent has been administered, receiving fluorescence emitted from the subject part accompanying the irradiation of the excitation light, A fluorescence image generated from the received fluorescence is used to diagnose the presence or absence of a lesion in the subject. [0003] On the other hand, for example, Japanese Unexamined Patent Application Publication No. 2011-136005 ...

Problems solved by technology

[0005] Therefore, for example, when treating a lesion included in the fluorescence image, it is difficult to estimate the actual size of the lesion, so it is impossible to select a treatment instrument suitable for treating the lesion. The problem of prolonged treatment for this lesion

[0006] On the other hand, in Japanese Patent Laid-Open No. 2011-136005, there is no specific mention of the structure for estimating the actual size of the lesion included in the fluorescence image, that is, the problem of prolonged treatment for the lesion still arises.
