BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foot switch for a surgical device used for a surgical device in which an operator sits on a chair and performs an operation.

[0002]

2. Description of the Related Art Conventionally, a surgical apparatus in which an operator sits on a chair to perform an operation, for example, an ophthalmic surgical apparatus used for cataract surgery is known.

[0003] As shown in FIG. 3, an ophthalmic surgical instrument 10 comprises:
The apparatus has a hanging bracket 16 for suspending a perfusate bottle 14 for supplying a perfusate to the apparatus main body 12. The hanging bracket 16 can arbitrarily change the height at which the perfusate bottle 14 is suspended with respect to the apparatus main body 12. It is supposed to be. An irrigation conduit 18 is connected to the perfusate bottle 14, and a handpiece 20 is provided at the tip of the irrigation conduit 18.

Further, the handpiece 20 has a suction conduit 2.
2 is connected to the suction pipe 22 and the suction pump 2
4 are connected. Further, the suction conduit 22 has a pressure sensor 26 for detecting the pressure in the suction conduit 22 and automatically controlling the pressure of the suction pump 24 to maintain the intraocular pressure within a predetermined range. It is provided at a position corresponding to the eye height (h). In the figure, 36
Is a microscope used by the operator 34.

A foot switch 38 having a built-in switch for turning on and off a transmitter for driving an ultrasonic chip (not shown) built in the handpiece 20 is connected to the apparatus main body 12. The foot switch 38 is placed on the floor.

Next, the operation will be described.

The patient 30 is laid on the bed 28 and the patient 30
The height of the hanging bracket 16 is adjusted so that the height from the eye to the liquid level of the perfusate bottle 14 becomes 65 cm, which maintains normal intraocular pressure. The operator 34 then makes a small cut in the capsule that houses the lens through the opening.

Then, the operator 34 operates the foot switch 38
By turning on and off, the ultrasonic tip of the handpiece 20 is inserted into the crystalline lens through the opening created while viewing the microscope 36. Further, with the vibration of the ultrasonic tip inserted into the lens, the solidified and clouded lens is crushed.

At the same time, the suction pump 24 is driven, and the crushed lens tissue is sucked through the handpiece 20 and the suction conduit 22 by the suction force of the suction pump 24.

[0010]

In the conventional foot switch device for a surgical device, when an operator operates the foot switch 38 while sitting on a chair, the height of the patient is limited or a plurality of foot switches are operated. In this case, there is a problem that the height of each switch is different or that the foot cannot easily reach the foot switch depending on the physique of the operator.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and is intended for a surgical apparatus capable of positioning a switch unit at a desired height of an operator by moving up and down a switch unit having a built-in switch. It is an object to provide a foot switch device.

[0012]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and a foot switch device for a surgical device according to the present invention has a switch unit having a built-in switch and a switch unit which is moved up and down. A jack is provided, and the switch unit can be positioned at an arbitrary height from the jack .

[0013]

According to the above construction, the foot switch device for a surgical device according to the present invention, when it is desired to adjust the switch portion to a height desired by an operator, positions the switch portion having a built-in switch up and down by the elevating portion. .

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing a foot switch device for a surgical device according to the present invention.

The foot switch device 40 has a pedestal 42, and a jack 44 is disposed on the pedestal 42. The jack 44 expands and contracts by rotating a handle 46 in a predetermined direction. I have. A holding member 48 having a U-shape in a front view is disposed above the jack 44, and a switch unit 50 having a built-in switch is disposed on the holding member 48.

Therefore, the switch unit 5 is set to the height desired by the operator.
When it is desired to position 0, the switch unit 50 incorporating the switch is moved up and down by the jack 44 to perform positioning.

[0018]

[0019]

[0020]

[0021]

[Effects of the Invention] As described above, according to the present invention,
The switch unit with built-in switch is raised and lowered by jacks to position the height, so the switch unit is positioned at the operator's desired height, preventing the patient's height from being limited When operating a plurality of foot switches, the height of each switch can be the same, and the feet can easily reach the foot switches according to the physique of the operator.
