Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a moving device for a microscope, particularly a surgical microscope.

For example, when performing surgery using a surgical microscope, the microscope must be rotated at least in the horizontal plane and vertically so that the necessary parts of the patient can be observed freely from various angles and distances. It is attached to the free end of the moving frame arm. In this case, to move the microscope, you place your fingers on the microscope's binoculars, aiming camera, etc., but these parts were originally used to adjust the elevation angle of the microscope and move it up and down. Because it was a small object, it was not suitable for moving the entire microscope, and it had the disadvantage of being difficult to operate. Therefore, during actual use, the operator usually has to touch any part of the microscope to move or rotate the microscope, which requires constant disinfection of the entire microscope, making handling cumbersome. There was a certain drawback.

In order to eliminate such drawbacks, for example, it is possible to incorporate a drive mechanism and control the drive of the motor that serves as the drive source with a foot switch.
Generally, operating rooms are already equipped with many foot switches, and increasing the number of foot switches any further may increase the risk of operational errors.
Undesirable. Furthermore, if all movements of the microscope were to be electrically operated, the apparatus would be extremely complicated and large, and the operation would be troublesome, which is not preferable. It is therefore advantageous to move the pedestal arm manually, but in this case it is necessary to move the microscope by hand, as in the past, and the disadvantages mentioned at the beginning are still not solved.

The purpose of the present invention is to eliminate the various drawbacks and inconveniences mentioned above, to make it possible to easily move a microscope through extremely natural operations, and to easily control the drive source motor without adding a foot switch. The present invention aims to provide a microscope moving device that allows the user to move the microscope.

In the moving device of the present invention, a microscope is attached to the free end of a pedestal arm that can be rotated at least in a horizontal plane and can also be rotated in a vertical plane through a casing, and the microscope is moved relative to the casing inside the casing. A drive mechanism and a drive source motor for moving the housing relative to the frame arm and/or the frame arm are housed, at least one grip is rotatably provided on the outer wall of the housing, and a grip is provided inside the housing. At least one switch driven by rotation is provided, this switch is connected to the power supply circuit of the drive source motor, and the microscope can be moved by gripping the grip and rotating the pedestal arm. The present invention is characterized in that the drive source motor can be controlled by rotating the grip at the same time.

Such a moving device of the present invention is particularly suitable for application to a surgical microscope, and in this case, it is further preferable that at least the portion of the grip gripped by the operator is removable. The reason is that in this way, only this part needs to be disinfected.

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing the configuration of an example of a microscope moving device according to the present invention, in which a microscope 1 is attached to the free end of a pedestal arm 3 via a casing 2. As shown in FIG. This pedestal arm 3 is known, and for example, US Pat.
4170336 and the drawings are shown. This pedestal arm is fixed at an appropriate height to a stand 4 placed on the floor.
It can rotate in a horizontal plane as well as in a vertical plane.

In this example, the case 2 is composed of two parts 2A and 2B, and the part 2A is attached to the part 2B so as to be rotatable about a shaft 5. That is, the axis 5 serves as an axis of rotation for the elevation and elevation of the microscope 1. part 2
B is attached to the free end of the pedestal arm 3 by the attachment shaft 6. In addition, the microscope 1 is connected to the housing part 2 via the rail 7.
Connect to A. Further, a pair of grips 8A and 8B are attached to the outer wall of the casing portion 2A. The operator can hold the grips 8A and 8B to move the microscope to a desired position. Therefore,
This movement becomes extremely easy.

In the present invention, the grips 8A and 8B are rotatably attached, and by rotating the grips, a switch is driven, and the drive source motor of the drive mechanism built into the case 2 is activated by turning the switch on and off. Be in control. In this example, this drive mechanism includes a mechanism for rotating the casing portion 2A and therefore the microscope 1 about the elevation rotation axis 5, and a mechanism for rotating the microscope 1 around the elevation rotation axis 5.
A mechanism is built into the case to move it up and down with respect to the case portion 2A using rails 7. Since these drive mechanisms themselves are known, further detailed explanation will be omitted.

Next, the drive mechanism of the switch driven by the grip 8A will be explained with reference to FIG. 2a. In this example, the grip 8A includes a grip main body 10 and a cover 11 placed thereon. cover 1
1 can be attached to and detached from the grip body 10 by a click mechanism 12. Therefore, it is only necessary to remove this cover 11 and attach a new sterilized cover, and there is no need to disinfect the grip body 10.

The grip body 10 is rotatably attached via bearings 15 and 16 attached to the wall 13 and support plate 14 of the case 2A. A flange 10A is integrally formed on the grip body 10, and this flange 10A
A pin 17 is installed in the wall 13, and the pin 17 is inserted through an arcuate opening 13A in the wall 13, as clearly shown in FIG. 2c. Figure 2b shows the case from the inside with the wall 13 and support plate 14 removed; the pin 17 is passed through the groove of the hook 18;
is supported on the support plate 14 by a leaf spring 19. Actuators 20A and 21A of microswitches 20 and 21 are arranged on both sides of this hook 18. Therefore, when grip 8A is held and rotated in the direction of arrow A in FIG.
is driven, the drive source motor rotates in one direction,
In FIG. 1, the housing portion 2A and the microscope 1 are rotated downward about the shaft 5 as shown by arrow C.
When the grip 8A is returned to the neutral position, the switch 20 is turned off and rotation is stopped. On the other hand, grip 8A
When the switch 21 is turned in the direction of arrow B, the switch 21 is turned on, the drive source motor is reversely rotated, and the housing portion 2A and the microscope 1 are rotated in the direction of arrow D.

Further, the other grip 8B and the part driven by it are constructed in the same manner, and by rotating it toward the front, the microscope 1 is displaced downward relative to the housing section 2A, and the microscope 1 is rotated toward the rear. By moving, the upper part can be displaced.

As described above, according to the moving device of the present invention, a grip is provided for manually rotating the microscope in a horizontal plane and a vertical plane, and further, by rotating this grip, elevation rotation and vertical movement can be performed electrically. Since it is movable, it is very easy to operate and does not require a foot switch. In other words, since you can operate the microscope while holding the grip, it becomes easier to follow the movements of the microscope intuitively. In addition, since the operator only needs to hold the grip and does not need to touch other parts, disinfection is extremely easy as only the grip needs to be disinfected. In particular, by providing the cover detachably to the grip body as in the above-described embodiment, the grip body does not need to be sterilized, making it easier to handle.

The present invention is not limited to the above-mentioned example, but can be modified in many ways. For example, in the above example, the grips 8A and 8B are rotated to perform elevation, rotation, and vertical movement.
Any movement that can be driven by an electric motor, such as fine focusing, coarse focusing, and tilting to the left and right, can be performed. Further, in the above example, both grips are rotatable, but at least one of the grips may be rotatable, and the other grip may be fixed. Further, the on/off control of the switches by rotation of the grip can be performed by various mechanisms, and if necessary, one grip can be configured to drive three or more switches.
