Abstract

PROBLEM TO BE SOLVED: To provide a device support structure of a stand device which can freely rotate a surgical microscope independently of an electronic image display device.SOLUTION: As an electronic image display device 14 is supported by a tip member 3 separately from a surgical microscope 7 via an auxiliary arm 13, the supporting state of the electronic image display device 14 is not influenced by rotating the surgical microscope 7 by a main operator A. Consequently, the main operator A can rotate the surgical microscope 7 freely without need of caring about the state of an assistant B.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a device support structure for a stand device.

  A surgical microscope used in neurosurgery or the like is supported by a support arm extending laterally from a stand device. A tip member that always maintains a vertical state is pivotally supported at the tip of the support arm, and a rotating body that is rotatable about the vertical axis is provided below the tip member. The operating microscope is supported by the rotating body via a suspension arm, and the observation direction of the operating microscope can be freely selected while rotating the rotating body together.

  In addition, since the operation is performed not only by the main operator but also by the assistant, the rotating body supports the electronic image display device via the auxiliary arm. On the electronic image display device, the same image as the operative field observed by the main surgeon with the operation microscope is displayed three-dimensionally. The assistant can assist the operation while observing the electronic image display device. Since both the surgical microscope and the electronic video display device are supported by the rotating body, the surgical microscope and the electronic video display device rotate together, and the positional relationship between them is always constant (see, for example, Patent Document 1).

Japanese Patent Laid-Open No. 2014-200294

  However, in such a related technique, when the main surgeon rotates the surgical microscope, the electronic image display device also rotates together. Therefore, when the main surgeon rotates the surgical microscope, the assistant is always an assistant. It was necessary to care about the condition, and it was not possible to rotate freely while looking at the eyepiece of the surgical microscope.

  The present invention has been made paying attention to such a related technique, and an object of the present invention is to provide a device support structure for a stand device that can freely rotate a surgical microscope irrespective of an electronic image display device. .

  According to the first aspect of the present invention, a tip member that is always maintained in a vertical state is pivotally supported at the tip of a support arm that extends in the lateral direction of the stand device, and the lower part of the tip member is rotatable about a vertical axis. A rotating body is pivotally supported, and a surgical microscope is supported on the rotating body via a suspension arm, and an electronic image display device is supported on the tip member via an auxiliary arm.

  According to the second aspect of the present invention, a protrusion projecting in the horizontal direction is formed on the tip member, and a base end portion of the auxiliary arm is rotatably attached to the protrusion in the horizontal direction. An electronic video display device is supported at the tip.

  According to the first aspect of the present invention, since the electronic image display device is supported on the tip member different from the operation microscope via the auxiliary arm, the electronic image display device can be used even when the main operator rotates the operation microscope. There is no effect on the support status. Therefore, the main operator does not have to worry about the condition of the assistant, and can freely rotate the surgical microscope.

  According to the second aspect of the present invention, since the auxiliary arm that supports the electronic video display device is rotatably attached to the protrusion formed on the tip member in the horizontal direction, the electronic video display device is operated. It can be rotated independently of the microscope.

  1 to 3 are views showing a preferred embodiment of the present invention.

  The stand device 1 has a support arm 2 extending in the lateral direction. The support arm 2 has a structure using a parallel link, and the tip is constituted by a tip member 3. Even if the support arm 2 is moved up and down or back and forth, the tip member 3 is always maintained in a vertical state.

  A cylindrical shaft support 4 is integrally formed at the lower portion of the tip member 3, and a rectangular box-shaped rotating body 5 is assembled to the shaft support 4 via a bearing 6. Therefore, the rotating body 5 is rotatable in the horizontal direction around the vertical axis V which is the central axis of the shaft support portion 4.

  A surgical microscope 7 is supported on a side surface of the rotating body 5 by a U-shaped suspension arm 8. The surgical microscope 7 includes an objective optical system, a zoom optical system, and an eyepiece optical system, and three-dimensionally displays an optical image of the surgical part G having binocular parallax from the pair of eyepieces 9 in the direction of viewing by the main operator A. Can be observed. In addition, a camera 10 capable of stereoscopic imaging is also provided at the upper part of the operation microscope 7.

  The tip member 3 is integrally formed with a protrusion 11 protruding in the horizontal direction. A proximal end portion of the auxiliary arm 13 is attached to the distal end of the projection 11 via a fulcrum 12 so as to be rotatable in the horizontal direction, and an electronic image display device 14 is supported on the distal end portion. That is, the base end portion of the auxiliary arm 13 is supported around the vertical axis (fulcrum 12) parallel to the vertical axis V of the rotating body 5 and offset in the horizontal direction at the fulcrum 12.

  By displaying a pair of left and right electronic images having binocular parallax photographed by the camera 10 of the surgical microscope 7 on the electronic image display device 14, the assistant B can use the same surgical field G as the main operator A from the eyepiece 15. Can be observed stereoscopically.

  Since the surgical microscope 7 is attached to the rotating body 5 and the electronic image display device 14 is attached to the tip member 3 in this way, the main operator A rotates the surgical microscope 7 during the operation, and the surgical field G by the surgical microscope 7 Even if the viewing direction is changed, the supporting state of the electronic video display device 14 is not affected. Therefore, the main operator A can freely rotate the surgical microscope 7 without worrying about the state of the assistant B.

  Similarly, the assistant B does not affect the support state of the surgical microscope 7 even if the electronic image display device 14 is rotated about the fulcrum 12 together with the auxiliary arm 13. Therefore, the assistant B can also rotate the electronic image display device 14 irrespective of the surgical microscope 7.
