Problems solved by technology

[0006] However, in a hydraulically driven microscope device, when coarsely moving the surgical microscope in the vertical direction, since the first and second arms are also driven up and down integrally, there is a problem that a large amount of driving energy is consumed.

Embodiment approach 1

[0035] [constitute]

[0036] exist figure 1 Among them, 1 is a microscope device for surgery, 2 is a support base of the microscope device 1 for surgery, 3 is a pillar integrally provided with the support base 2 facing up and down, and 4 is a first arm mounted on the upper end of the pillar 3. .

[0037] The first arm 4 is formed by a support part 4a rotatably attached to the upper end of the support column 3 around a vertical rotation axis (vertical axis), and an arm part 4b provided continuously with the support part 4a horizontally. word shape. 5 is a fixing screw for fixing the supporting part 4a to the upper end part of the pillar 3.

[0038] In addition, 6 is the second arm (swing arm) of the parallel link type. The second arm 6 has a first support member 7, a second support member 8, and a pair of connecting rods 9, 10. The first support member 7 is horizontally rotatably mounted on the second arm through a rotating shaft (not shown) extending up and down. On the f...

Deformed example 1

[0121] In the embodiment described above, if the operation signal from the upward coarse motion switch 30 is input to the calculation control circuit 27, the first drive motor 18 of the first electric up and down movement device 17 is controlled to make the supporting part 19 relatively At the second arm 6, the upward micromotion is performed at the speed v1, and at the same time, the second drive motor 26 of the second electric vertical movement device 24 is controlled to make the surgical microscope 25 slightly upward at the speed v2 relative to the supporting frame 23. As a result, the surgical microscope 25 is moved upward and coarsely at the speed (v1+v2) relative to the second arm 6. However, it is not limited to this configuration.

[0122] That is, when the operation signal from the ascending coarse switch 30 is input, the supporting part 19 moves at a speed V (V>>v1) relative to the second arm 6 through the first electric up and down movement device 17 through the cal...

Abstract

Provided is an operation microscope apparatus including: a support base (2); a pillar (3) supported by the support base (2); a parallel link type second arm (6) whose base end portion is held to the pillar (3) so as to be rotated upward and downward; a plurality of electrically-operated upward-and-downward-motion devices (17, 24); and an operation microscope (25) supported to a tip portion of the second arm (6) through the plurality of electrically-operated upward-and-downward-motion devices (17, 24). The operation microscope apparatus further includes an arithmetic and control circuit 27 for controlling the plurality of electrically-operated upward-and-downward-motion devices (17, 24). In the operation microscope apparatus, the plurality of electrically-operated upward-and-downward-motion devices (17, 24) are connected in series.

Description

technical field [0001] The present invention relates to a surgical microscope device in which a surgical microscope is movably supported on a support. technical background [0002] As a conventional surgical microscope device, a hydraulically driven microscope device is known. In this hydraulically driven microscope device, a support rod is fitted to a cylindrical support so that it can be raised and lowered, and can be raised and lowered by hydraulic pressure or the like. The support rod is set in a driving manner, the base end of the first arm is installed on the upper end of the support rod, and one end of the second arm is horizontally rotatably installed on the free end of the first arm, and the upper and lower ends of the arm are electrically driven A moving device mounts a surgical microscope on the other end of the second arm. [0003] In this microscope device, the first and second arms and the micro-movement device are raised and lowered by driving the support rod...
