2. Description of the Related Art Ophthalmic surgery includes cataract surgery, vitreous surgery, etc., but the ultrasonic output, suction pressure, suction flow rate, etc. should be adjusted appropriately depending on the disease name or the difference in symptoms and the process of each surgery. Adjustments need to be changed. Parameters are set by balancing each numerical value, and the operator selects each parameter (numerical value group) set as necessary.
The numerical value of each parameter is changed by using a setting button or the like attached to the operation panel of the main device.

There is also a surgical apparatus having a memory function capable of storing several examples of each parameter group expected to be required in advance.
If necessary, these recorded parameters can be called by operating a switch on the operation panel of the apparatus during surgery, and an appropriate parameter can be selected.

[0004]

The operator does not have to touch the operation panel of the device, even if he / she changes the parameter during the operation or calls a pre-stored parameter group, without taking his / her eyes off the microscope etc. of the surgical machine. Since it should not be done, there was an inconvenience that it took time to change and call. In addition, it has been inconvenient to return the focus of the eye once away from the microscope to the affected area during the operation and concentrate the nerve again. Also, since the operator's hands are sterilized, the operating panel of the surgical device, which the operator directly touches, must also be sterilized.
There is a drawback that it takes time to sterilize the device.

Therefore, an object of the present invention is to overcome the above-mentioned drawbacks and to perform memory switching by a foot switch by a method of substituting a part of the operation originally performed on the operation panel, such as memory switching, by a foot switch. Accordingly, it is an object of the present invention to provide an ophthalmologic surgery apparatus with a memory switching foot switch that allows an operator to easily change parameters without using a hand and while looking through a microscope.

[0006]

An eye surgery apparatus with a memory switching foot switch according to the present invention for achieving the above object is an eye surgery apparatus having a memory function capable of storing a plurality of various operation parameter groups. This is a configuration in which a foot switch is provided as a switch for switching any of various surgical parameter groups that have been set and stored in advance.
Further, in another embodiment, a switch for switching arbitrary various surgical parameter groups is provided in both the switch of the surgical apparatus body and the foot switch.

In order to achieve the above object, the foot switch used in the eye surgery apparatus with a memory switching foot switch according to the present invention is a foot switch for an eye surgery apparatus, which includes a linear switch pedal and stepping / sideways provided on both sides thereof. The configuration includes an inversion switch, and numerical values stored as various surgical parameters have a structure including data relating to ultrasonic output, suction pressure, suction flow rate, and the like.

[0008]

The present invention for achieving the above object is constituted by a foot switch for memory switching and a switching device for generating a control signal. By pressing or tilting each switch of the foot switch, A control signal for switching to a preset memory group or other operation by the switching device is sent to the surgical device to change arbitrary parameters of the surgical device. Therefore, according to this apparatus, the operator can switch to an arbitrary memory group of the surgical apparatus or other operations by operating the switches provided on the foot switch without taking his eyes off the microscope. Further, since the operator does not use a sterilized hand because he / she operates with his / her feet, it is not necessary to sterilize the operation panel of the surgical apparatus.
