Abstract

An enlarging optical system having an objective lens and an ocular lens is received in a body of a microscope. A beam splitter is received in the body on an optical path of the enlarging optical system. This beam splitter is disposed between the objective lens and the ocular lens. A monitor television is also received in the body. An image obtained by an endoscope is displayed in this monitor television. The image displayed in the monitor television is reflected by the beam splitter toward the ocular lens.

Claims

1. A medical observing instrument comprising:

(a) a microscope having a body and an enlarging optical system received in said body, said enlarging optical system including an objective lens and an ocular lens to thereby obtain a first image, said enlarging optical system further including a beam splitter disposed between said objective lens and said ocular lens;

(b) an endoscope separated from said microscope; and

(c) image display means connected to said endoscope and displaying a second image obtained by said endoscope, said image display means being received in said body of said microscope and placed adjacent to said beam splitter, said second image displayed in said image display means being sent to said ocular lens through said beam splitter.

2. A medical observing instrument according to claim 1, in which said endoscope includes an image sensor, and said image display means includes a monitor television connected to said image sensor.

3. A medical observing instrument according to claim 2, further comprising detection means for detecting the conditions of a patient, data from said detection means being displayed in said monitor television.

4. A medical observing instrument according to claim 1, in which said endoscope has a bundle of optical fibers for transmitting an image therethrough, said bundle of optical fibers being allowed to extend from said endoscope, an end face of an extended portion of said bundle of optical fibers being provided as said image display means.

5. The medical observing instrument according to claim 1, wherein said first image and said second image are positionally offset with each other in the view field of said ocular lens of said enlarging optical system.

6. The medical observing instrument according to claim 1, in which a shutter is disposed between said image display means and said beam splitter.

7. The medical observing instrument according to claim 1, in which said microscope further has a second enlarging optical system received in said body and disposed side by side with the first mentioned enlarging optical system, said second enlarging optical system including a second objective lens and a second ocular lens.

8. The medical observing instrument according to claim 7, in which the second enlarging optical system further includes a second beam splitter disposed between the second objective lens and the second ocular lens, an additional lens and an image sensor being placed adjacent to the second beam splitter, an image coming from the second objective lens being sent to the image sensor through the second beam splitter and said additional lens, said image sensor being in connection with a second monitor television separately situated from the microscope.

9. A medical observing instrument comprising:

(a) a microscope having a body and an enlarging optical system received in the body, said enlarging optical system including an objective lens and an ocular lens to thereby obtain a first image;

(b) an endoscope separated from the microscope; and

(c) image display means connected to the endoscope and displaying a second image obtained by the endoscope, said image display means being received in the body of the microscope and disposed adjacent to an optical path of said enlarging optical system and faced with said ocular lens, the second image displayed by said image display means being located within a view field of said ocular lens.

10. The medical observing instrument according to claim 9, in which the microscope further includes a second enlarging optical system received in the body and disposed side by side with the enlarging optical system, said second enlarging optical system including a second objective lens and a second ocular lens.

11. A medical observing instrument comprising:

(a) a microscope having a body and an enlarging optical system received in the body, said enlarging optical system including an objective lens and an ocular lens to thereby obtain a first image;

(b) an endoscope separated from the microscope; and

(c) image display means connected to the endoscope and displaying a second image obtained by the endoscope, said image display means being received in the body of the microscope;

(d) an additional ocular lens received in said body of said microscope in such a manner as to be spaced apart from said ocular lens of said enlarging optical system, said image display means being faced with said additional ocular lens.

12. A medical observing instrument comprising:

(a) a microscope having a body and a pair of enlarging optical system received in the body, each of said pair of enlarging optical system including an objective lens and an ocular lens, wherein said body of said microscope has a base portion and a pair of ocular portions projecting from said base portion, said ocular lens of said pair of enlarging optical systems being received respectively in said pair of ocular portions;

(b) an endoscope separated from said microscope; and

(c) image display means connected to said endoscope and displaying an image obtained by said endoscope, said image display means being disposed on an outer surface of said base between said pair of ocular portions.
