Embodiment approach 1

[0030] [constitute]

[0031] In Fig. 1, 1 is a surgical microscope device, 2 is a support base of the surgical microscope device 1, 3 is a pillar that is integrated with the support base 2 facing up and down, and 4 is mounted on the upper end of the pillar 3. The first arm.

[0032] The first arm 4 is formed by a support part 4a that is rotatably mounted on the upper end of the pillar 3 around a vertical rotation axis (vertical axis), and an arm part 4b that is arranged horizontally and continuously with the support part 4a to be slightly L Word-like. 5 is a fixing screw for fixing the supporting portion 4a to the upper end of the pillar 3.

[0033] In addition, 6 is a parallel link type second arm (swing arm). The second arm 6 has a first support member 7, a second support member 8, and a pair of links 9, 10. The first support member 7 is horizontally rotatably mounted on the first support member 7 via a rotating shaft (not shown) extending vertically. On the free end (front end)...

Deformed example 1

[0116] In the embodiment described above, if the operation signal from the ascending coarse switch 30 is input to the calculation control circuit 27, the operation control of the first drive motor 18 of the first electric vertical movement device 17 causes the support portion 19 to face each other. The second arm 6 is moved up and down at a speed v1, and at the same time the second drive motor 26 of the second electric up-and-down movement device 24 is controlled to move, so that the surgical microscope 25 is moved up and down at a speed v2 with respect to the support bracket 23. As a result, the surgical microscope 25 is moved up coarsely with respect to the second arm 6 at a speed (v1+v2). However, it is not limited to this structure.

[0117] That is, when the operation signal from the ascending coarse switch 30 is input, the arithmetic control circuit 27 uses the first electric vertical movement device 17 to make the support part 19 relative to the second arm 6 at a speed V (V...

Abstract

An operation microscope apparatus includes: an operation microscope (25) supported to a pillar through an electrically-operated elevating device for rough-motion (first upward-and-downward micro motion device 17) ; a lens support arm (51) supported to a support portion of the operation microscope (25) so as to be movable between a use position at which the lens support arm (51) is extended downward and a storage position at which the lens support arm (51) is stored upward; a front lens (74) held by the lens supported arm (51); a control unit for controlling the electrically-operated elevating device (arithmetic and control circuit 27) ; a switch for upward-and-downward rough-motion (30,31 or 94,95); and a detection unit for detecting a storage state of the lens support arm (51) to output a detection signal (microswitch 91). In the apparatus, only when the detection signal is received, the control unit (arithmetic and control circuit 27) controls the electrically-operated elevating device (first electrical upward-and-downward micro motion device 17) by operating the switch (30,31 or 94,95) to allow the operation microscope (25) to roughly move upward and downward.

Description

Technical field [0001] The present invention relates to a surgical microscope device. The surgical microscope device is provided with a front lens that can be arranged in front of the objective lens of the surgical microscope. At the same time, the surgical microscope can be moved up and down by an electric lifting device. Supported on the microscope support. Background technique [0002] As a conventional surgical microscope system, a swing type microscope is known. The swing type microscope has a first arm mounted on the upper end of a pillar so as to rotate horizontally, and at the same time, it can rotate horizontally on the free end of the first arm. One end of the second arm (microscope support portion) is swingably attached to one end, and an operating microscope is attached to the other end of the second arm through an electric vertical micro-movement device (see, for example, Japanese Patent Laid-Open No. 6-22980). [0003] In addition, as this surgical microscope is kno...
