Deformed example 1

[0044] In addition, in figure 2 , image 3 In the figure, an example is shown in which a pair of left and right microscope stands 17, 17' and assistant microscope units Su, Su' are provided, but the present invention is not limited thereto. For example, if Figure 8 , Figure 9 As shown, only one microscope stand 17 can also be provided, and the microscope stand 17 can be moved along the arc-shaped guide portion 15 of the guide rail 14 in the circumferential direction of the lens barrel 12a, thereby disposing the microscope stand 17 at the left and right use positions (opening 15L , 15R position or opening 15L', 15R' position) either one.

Deformed example 2

[0046] In addition, in the embodiment described above, the arc-shaped guide portion 15 and the example in which the arc-shaped guide portion 15 and the linear guide portions 16, 16' are provided on the guide rail 14 have been shown, but it is not limited to this.

[0047] For example, the figure 2 , image 3 The linear guides 16, 16' of the shown guide rail 14 are shown as Figure 10 ~ Figure 12 omitted as shown, leaving only the figure 2 , image 3 The arc-shaped guide part 15 serves as Figure 10 ~ Figure 12 Rail 14' shown.

[0048] At this time, through the Figure 10 The left and right sides of the support 13 are provided with a dismounting space 18 (space not used), and the microscope base 17' is removed from the Figure 11 When the use position of the stand 13 is moved to the detachment space (non-use position) 18 on the side of the stand 13, the microscope stand 17' can be detached from the end of the guide rail 14' together with the unshown helper microscope u...

Abstract

An operation microscope includes an illumination optical system for illuminating a subject, a microscope body of an main observation optical system for observing a subject, a microscope unit for an assistant attached to the microscope body, and a guide rail which is disposed in the lens barrel of the microscope body, and extends in a circumferential direction about a center of an optical axis of an objective lens of the microscope body. The microscope unit for an assistant is disposed in the guide rail to be movable between a usage position and a non-usage position in a circumferential direction of the lens barrel.

Description

technical field [0001] The present invention relates to a surgical microscope with an assistant microscope unit. Background technique [0002] Among conventional surgical microscopes, there is known a microscope comprising: a microscope main body provided with a main observation optical system for observing an object; and an assistant microscope unit attached to the microscope main body (for example, refer to Patent Document 1). . [0003] Among such surgical microscopes, there is known a microscope in which the assistant's microscope unit is moved in order to align the assistant's standing position during the operation, such as Figure 13 As shown, the assistant microscope unit 3 is mounted on the lens barrel 2 of the microscope main body 1 so as to be rotatable in the circumferential direction. [0004] Patent Document 1: Japanese Patent Laid-Open No. 2006-280805 [0005] However, in this surgical microscope, the assistant microscope unit 3 is configured such that the an...
