Therefore, when it is desired to position the switch unit 50 at the height desired by the operator, the switch unit 50 including the switch is elevated and positioned by the jack 44.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a foot switch device for a surgical device used in a surgical device in which an operator sits on a chair to perform surgery.

[0002]

[Prior Art]

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

As shown in FIG. 3, the ophthalmic surgical instrument 10 has a suspending metal fitting 16 for suspending the perfusion liquid bottle 14 for supplying the perfusate to the device body 12, and the suspending metal fitting 16 is a device. The height at which the perfusate bottle 14 is suspended with respect to the main body 12 can be arbitrarily changed. An irrigation conduit 18 is connected to the irrigation liquid bottle 14, and a handpiece 20 is provided at the tip of the irrigation conduit 18.

Further, a suction pipe 22 is connected to the handpiece 20, and a suction pump 24 is connected to the suction pipe 22. Further, in the suction conduit 22, a pressure sensor 26 for keeping the intraocular pressure within a predetermined range by detecting the pressure in the suction conduit 22 and automatically controlling the pressure of the suction pump 24 is provided. It is provided at a position corresponding to the eye height (h) of 30. The numeral 36 in the figure is a microscope used by the operator 34.

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

Next, the operation will be described.

The patient 30 is laid on the bed 28, and the height of the suspending metal fitting 16 is adjusted so that the height from the patient's 30 eye to the liquid surface of the perfusate bottle 14 is 65 cm to keep the intraocular pressure normal. To do. The surgeon 34 then makes a small incision through the opening in the capsule containing the lens.

Then, the operator 34 turns the foot switch 38 on and off to insert the ultrasonic tip of the handpiece 20 into the lens through an opening created while looking at the microscope 36. Furthermore, as the ultrasonic tip inserted into the crystalline lens vibrates, the crystalline lens that solidifies and becomes cloudy is crushed.

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

[0010]

[Problems to be solved by the device]

 In the conventional foot switch device for a surgical apparatus, when the operator sits on a chair and operates the foot switch 38, the height of the patient is limited, or when the foot switches are operated, the height of each switch is different. However, depending on the physique of the surgeon, it is difficult for the foot to reach the foot switch.

The present invention has been made in order to solve the above problems, and is for a surgical device capable of lifting and lowering a switch part having a switch to position the switch part at a height desired by an operator. An object is to provide a foot switch device.

[0012]

[Means for Solving the Problems]

 The present invention has been made in view of the above circumstances, and a foot switch device for a surgical device according to the present invention includes a switch section having a built-in switch and an elevating section for elevating the switch section. It is characterized in that the switch portion can be positioned at the height of.

[0013]

[Action]

 Based on the above configuration, in the foot switch device for a surgical device according to the present invention, when it is desired to adjust the switch unit to a height desired by the operator, the switch unit including the switch is moved up and down by the elevating unit to position the switch.

[0014]

【Example】

 An 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 apparatus according to the present invention.

The foot switch device 40 has a pedestal 42, and a jack 44 is arranged on the pedestal 42. The jack 44 expands and contracts by rotating a handle 46 in a predetermined direction. There is. A holding member 48 having a U-shape when viewed from the front is provided on the upper portion of the jack 44, and a switch portion 50 having a built-in switch is provided on the holding member 48.

Therefore, when it is desired to position the switch unit 50 at the height desired by the operator, the switch unit 50 including the switch is lifted and positioned by the jack 44.

FIG. 2 is a perspective view showing another embodiment of the present invention.

The foot switch device 40 has a U-shaped holding member 52 when viewed from the front, and the holding member 52 is provided with a switch unit 50 having a built-in switch. Further, screw holes (not shown) are formed in the lower four corners of the holding member 52, and adjusting screws 54 are screwed into the screw holes.

Therefore, when the operator wants to position the switch unit 50 at a desired height, the switch unit 50 is moved up and down to be positioned by changing the screwing position of the adjusting screw 54 with respect to the screw hole.

[0021]

[Effect of the device]

 As described above, according to the present invention, since the switch part including the switch is configured to be moved up and down by the elevating part to position the height, the switch part is positioned at the height desired by the operator. As a result, the height of the patient can be prevented from being limited, and the height of each switch can be made the same when operating multiple foot-operated switches. Can be easily reached by the foot switch.
