DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for observing fluorescence of a living body, which enables normal endoscope observation and fluorescence observation using an endoscope.

[0002]

2. Description of the Related Art Fluorescence observation using an endoscope is performed by utilizing the fact that a living body emits fluorescence when irradiated with light (excitation light) in a specific wavelength range.

An endoscope used for performing such fluorescence observation connects an observation image obtained by an objective optical system arranged at the distal end of an insertion section with an image guide fiber bundle inserted into the insertion section. This is the same as that for normal observation that is transmitted to the eye and observed.

A television camera unit provided with a connection mechanism for connecting an eyepiece of an endoscope at a lower end has a normal image pickup for capturing a normal observation image passing through the eyepiece. A television camera for imaging and a television camera for imaging a fluorescence image with an image intensifier for amplifying the light intensity of the fluorescence observation image passing through the eyepiece for imaging.

[0005] Such a television camera unit is hung on the tip of an arm of a television camera stand having a rotation support arm connected in the middle by a plurality of rotary joints.

[0006] A wagon for mounting devices used simultaneously with the endoscope and the television camera unit, such as a light source device and a television monitor, is provided.
A TV camera stand is also set up on the wagon.

[0007]

A bed and various peripheral devices are arranged in an examination room in which a biological fluorescence observation apparatus is used, and the arrangement position of a wagon is often extremely limited. .

As a result, the range of rotation of the arm of the television camera stand interferes with devices and the like arranged around the arm,
In some cases, it becomes very difficult to operate the endoscope, and conversely, the operation of peripheral devices is hindered.

Accordingly, the present invention provides an apparatus as a whole that minimizes interference between the rotation range of a TV camera stand erected on a wagon and devices disposed around the same even when the arrangement position of the wagon is restricted. It is an object of the present invention to provide a fluorescent observation apparatus for a living body, which can make it easier to operate.

[0010]

In order to achieve the above object, a fluorescence observation apparatus for a living body according to the present invention is provided with a normal fluorescence observation apparatus for capturing a normal endoscopic observation image through an eyepiece of an endoscope. Hanging a TV camera unit including a TV camera for image capturing and a TV camera for fluorescent image capturing with an image intensifier for amplifying the light intensity of the fluorescence observation image passing through the eyepiece for capturing an image A TV camera stand for supporting the endoscope and a stand for fixing the TV camera stand in a living body fluorescence observation apparatus installed on a wagon for mounting devices used simultaneously with the TV camera unit. The fixing part is provided at a plurality of places of the wagon, so that the TV camera stand can be selectively erected and fixed at any of the plural places. It may be provided on the left and right opposite sides the position of the wagon.

[0011] Further, auxiliary member fixing portions for fixing the additional members are provided at a plurality of positions of the wagon so that the additional members other than the television camera stand can be selected and fixed to the wagon separately from the television camera stand. May be.
