Surgical observation system for observing, in three dimensions, a surgical site from two directions

摘要

Surgical observation system for observing, in three dimensions, a surgical site from two directions are provided herein. The surgical observation system may include a first image-acquisition optical system that obtains, from a first observation direction, a pair of optical images, having parallax, of a subject via a pair of apertures disposed side-by-side; and a second image-acquisition optical system that obtains, from a second observation direction in which an angle about an optical axis differs from that of the first observation direction, another pair of optical images, having parallax, of a subject via another pair of apertures disposed side-by-side.

1. A surgical observation system comprising:
a first image-acquisition optical system that obtains, from a first observation direction, a pair of optical images, having parallax, of a subject via a pair of apertures disposed side-by-side; and a second image-acquisition optical system that obtains, from a second observation direction in which an angle about an optical axis differs from that of the first observation direction, another pair of optical images, having parallax, of the subject via another pair of apertures disposed side-by-side, wherein areas of the apertures of the first image-acquisition optical system are larger than areas of the apertures of the second image-acquisition optical system, and the first image-acquisition optical system and the second image-acquisition optical system are disposed so as to satisfy the following conditional expression:
0.4≦L2/L1≦0.6  (1) where L1 is a distance between centers of the apertures of the first image-acquisition optical system, and L2 is a distance between centers of the apertures of the second image-acquisition optical system.
