[0002]

2. Description of the Related Art A foot switch 51 as an operation switch of a conventional surgical microscope 50 used for eye surgery or the like.
9 is connected to a control box 53 attached to a column 52 of a surgical microscope 50 using a slightly thick and flexible connection cable 54 and a connector 55. When the operator or an assistant steps on the foot switch 51, various operation signals are sent to the control box 53 of the surgical microscope 50 to operate various functions of the surgical microscope 50.

The operating microscope 50 is mounted on a base 65 for supporting the support column 52 so as to be movable on the floor surface, a first arm 61 supported by the support column 52, and a projecting end of the first arm 61. A second arm 62, an XY drive unit 63 attached to the protruding end of the second arm 62, and a zoom system, a focus system, an illumination system, etc., which are driven in the X and Y directions by the XY drive unit 63. The microscope main body 64 is provided, and the eye E to be inspected is observed by the microscope main body 64.

[0004]

However, in the above-mentioned foot switch 51 of the conventional surgical microscope 50, which is connected to the control box 53 by using the connection cable 54 and the connector 55, this operation is not possible. When the eye E to be inspected is observed by the microscope for operation 50 and an ophthalmologic operation is performed, the connection cable 54 is caught by the operator's or assistant's foot or equipment for operation and interferes with the operation of the operation microscope 50. There is a problem in that the blood pressure from the eye E to be inspected due to ophthalmic surgery adheres to the connection cable 54 and the hygiene is deteriorated.

Therefore, an object of the present invention is to provide a surgical microscope which has wireless operation signals sent from the operation switch to the surgical microscope to improve operability and has an operation switch which does not hinder hygiene. It is what

[0006]

According to the first aspect of the present invention,

Although the foot switch 1 described above is adapted to wirelessly transmit an operation signal in the form of a radio wave,
It is of course possible to wirelessly transmit the operation signal in a signal form of infrared rays or light in addition to radio waves, and by doing so, diversification of the signal form at the time of creating the foot switch 1 Can be achieved. For example, it is preferable to use infrared light or light when radio waves may cause other devices to malfunction. Conversely, when infrared light or light is used, the optical path may be blocked. When the number is large, it is preferable to use radio waves, and it may be appropriately selected for use.

According to the surgical microscope 2 using the foot switch 1 having the above-described configuration, when the foot switch 1 is stepped on, an operation signal for operating various functions is given to the receiving unit 13 of the surgical microscope 2. It is transmitted wirelessly in the form of radio waves, whereby the receiving unit 13 and the control box 1

To be done.

As a result, unlike the conventional example, the connection cable becomes unnecessary, and there is no possibility that a foot or the like is caught on the connection cable, and the operability is improved, and blood adheres to the connection cable as in the conventional example. There are no such concerns, and there will be no problems with hygiene.

Operation switch section 2 of the foot switch 1
Examples of 1 include two types of configurations shown in FIGS. 4 and 5. That is, FIG. 4 shows an operator foot switch 1A used by an operator, and FIG. 5 shows an assistant foot switch 1B used by an assistant. A foot-operated zoom switch is provided on the upper surface of the operator foot switch 1A. 41, a focus switch 42, an XY switch 43, and a vertical fine movement switch 44, and an assistant foot switch 1B is provided with a vertical coarse movement switch 45 and a power operation switch 46.

As described above, by making the function of the foot switch 1A for the operator different from that of the foot switch 1B for the assistant, the operating states of the operator and the assistant with respect to the surgical microscope 2 can be clearly distinguished. The surgical microscope 2 can be operated according to the role of each assistant, and eye surgery or the like can be efficiently performed.

FIG. 6 shows the operator foot switch 1A,
It shows a state in which each operation signal is wirelessly sent to the reception unit 13 by the assistant foot switch 1B.
In this case, if a plurality of receivers 13 having the same function are arranged on the wall surface of the base 3, the operator's foot switch 1
A, the degree of freedom in arranging the assistant foot switch 1B can be further increased.

Further, as shown in FIG. 7, for example, in the construction of the operator foot switch 1A, each switch piece of the slide switch 26 is operated to operate the zoom switch 41 and the focus switch 42 in the operator foot switch 1A. Is converted into the functions of the up / down coarse movement switch 45 and the power source operation switch 46 for the assistant, and the XY switch 4
3. The function of the vertical fine movement switch 44 can be canceled, and in this way, the operator's foot switch 1A can also be used as the assistant's foot switch 1B.

FIG. 8 shows another example of the arrangement of the receiving portion 13, in which, for example, a belt-shaped rotating body 47 is loosely fitted around the lower portion of the column 4, and the connecting cable 31 is connected to the rotating body 47. Is attached so that it can be extended and contracted, and the receiving portion 13 is attached to the end portion of the connection cable 31 so that the receiving portion 13 can move freely on the floor surface, and the receiving portion 13 has the foot switch 1A for an operator and an assistant. An operation signal is wirelessly transmitted from the foot switch 1B for use.

With such a configuration, the degree of freedom in arranging the foot switch 1A for the operator and the foot switch 1B for the assistant is increased, and the foot switch 1 for the operator can be selected according to the surgical situation.
A, the arrangement of the assistant foot switch 1B can be arbitrarily changed, and an ophthalmic surgery or the like can be efficiently performed.

Although the foot-operated foot switch 1 has been described as the operation switch in the above embodiments,
In addition, foot switch 1, operator foot switch 1
Even if a hand-held remote controller (hand switch) having the same configuration as A and the assistant foot switch 1B is configured, the same functions as those described above can be exhibited. In particular, when the assistant is a nurse, the hand switch is effective because the hand is usually not sterilized. Since the position can be moved by using the hand switch, there is an advantage that the assistant can operate at a position that does not block radio waves or infrared light. In this case, it is convenient to provide the receivers on the four surfaces of the support column 4.

Further, the function of the operation switch can be further enhanced if the operation signal transmitted wirelessly is used to operate the shutter of the photographing camera, the bed associated with the surgery, the surgical chair and the like.

According to the invention of claim 1, since the connecting cable is not used unlike the conventional example, the connecting cable is never caught on a foot or the like, and the operability can be improved and the sanitary aspect can be improved. It is possible to provide a surgical microscope having an operation switch that does not cause any trouble.

According to the second aspect of the present invention, there is provided a surgical microscope equipped with an operating switch that can clearly distinguish the operating states of the operator and the assistant with respect to the operating microscope and can efficiently perform ophthalmologic surgery. be able to.

According to the third aspect of the present invention, the degree of freedom in arranging the operator operation switch and the assistant operation switch is increased, and the operator operation switch and the assistant operation switch are arranged in accordance with the surgical situation. It is possible to provide a surgical microscope having an operation switch that can be changed and can efficiently perform ophthalmic surgery and the like.
