Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention This invention relates to a surgical bottle vertical movement device that can be used, for example, in ophthalmic surgery.

Conventional techniques: For example, in eye surgery, the cloudy part of the vitreous body inside the eyeball is removed from the eyeball, and irrigating fluid is put into the eyeball instead to maintain intraocular pressure. This irrigant is contained in a bottle, which is suspended from a support, and is injected into the eyeball from the bottle through a tube.

By the way, during this surgery, the vitreous body and fundus are observed through a contact lens placed on the surface of the eyeball. At this time, irrigation fluid is required to keep the cornea from drying out. This irrigation amount is different from the irrigation amount injected into the eyeball.

For this reason it is necessary to use two bottles of this type.

The two bottles come in the following combinations:

■ When using one bottle that is moved up and down by an electric motor and one that is moved up and down manually.

The bottle, which is moved up and down by an electric motor, can be adjusted to the correct height by the operator using a foot switch or the like.

■ When using two manual bottles.

In the case of problem (3) that the invention aims to solve, two columns are used side by side: a column equipped with a relatively large-scale electric motor vertical movement device and a column for manual vertical movement. Therefore, a large space is required, and it is not easy to place two pillars in a narrow operating room.

In the case of ■, the required space is somewhat smaller than in the case of ■. However, it is not easy to move the bottles up and down quickly and accurately because both bottles are manually operated.

OBJECTS OF THE INVENTION It is an object of the present invention to provide a surgical bottle vertical movement device that can save space by setting two different types of vertical movement bottles on one support.

SUMMARY OF THE INVENTION The gist of the present invention is a surgical bottle vertical movement device as set forth in the claims.

Means to solve problems Please refer to FIGS. 2 and 3.

It has a first bottle 44 and a second bottle 45.

The moving operation unit 46 is disposed within the support column 41 to move the first bottle 4
Move 4 up and down.

The first support section 42 is provided on the moving operation section 46 and supports the first bottle 44 .

The second support part 43 is attached around the support column 41 and can be manually moved up and down along the support column 41. The second support part 43 supports the second bottle 45.

The second support portion 43 has a gap portion 60 . The third support portion 42 is configured to pass through the gap portion 60 .

Function: The first bottle 44 and the second bottle 45 can each move up and down without interfering with each other.

Embodiment 1 [Ophthalmic Surgical Apparatus] FIG. 1a shows an ophthalmic surgical apparatus having an embodiment of the surgical bottle vertical movement device of the present invention.

In ophthalmic surgery, an aspirated object 34 is a cloudy part of the gel-like vitreous body 14 between the crystalline lens a and the retina of the subject's eye 13.

[1 suction section The suction section 1 is connected to the cutter 5 via a passage 8a. The cutter 5 has an insertion portion 5a. This insertion portion 5a is inserted into the interior of the eyeball 13 through the sclera IS of the eyeball 13. A suction port 30 is provided at the distal end of the insertion portion 5a. The cutter 5 is capable of cutting off the object to be sucked 34 that has entered the suction port 30. When the suction unit 1 operates, the excised object 34
can be sucked into the insertion portion 5a and through the passage 8a.

[Cutter drive unit 2] The cutter drive unit 2 has a compressed air tube 7'8b.
is connected. Compressed air is sent to the cutter 5 through the tube 8b, and the cutter 5 is actuated by the compressed air to cut off the object 34.

[Light source unit 3] The light source unit 3 includes an optical fiber 6a in the light guide 6.
It is now possible to send light through the light guide 6
The tip is inserted into the eyeball 13. The light guide 6 can illuminate the vicinity of the suction port 30.

[Perfusion section] The perfusion section has a perfusion tube 4a.

The first and second bottles 44 and 45, which will be described later, contain a /1 flow liquid. The irrigation fluid in the first bottle 44 can be sent into the eyeball 13 via the irrigation tube 4a. Note that sending the irrigation fluid can also be stopped by operating the stopper 4b. After the object to be aspirated 34 is excised and suctioned, this irrigation fluid instead fills the inside of the eyeball 13 to restore intraocular pressure.

During surgery, a contact lens 80 is placed on the surface of the eyeball, and the vitreous body and fundus are observed through this. At this time, irrigation from the second bottle 45 is supplied through the irrigation tube 4C so as not to dry the cornea. This perfusion tube 4
A stopper 81 is arranged in the middle of c as shown in FIG. 1b. Here, the shaft 81b of the knob 81a is
It penetrates a groove 81d provided so that the distance from the perfusion tube 1c changes, and by moving the knob 81a downward, the degree to which the knob 81a crushes the perfusion tube 4C can be changed.

If the knob 81a is moved to the lowest position, the flowing liquid is stopped.

Please refer to FIGS. 1 and 2.

[Surgical bottle vertical movement device 100] This device 100 includes a support 41, a first support portion 42, a second support portion 43, a first bottle 44, a second bottle 45, a movement operation portion 46, a base 47, etc. ing.

A movement operation section 46 is arranged inside the support column 41 .

The movement operation section 46 moves the first bottle 44 up and down along the support column 41. A wire 53 is wound between a pulley 51 of the motor 50 and another pulley 52, and a mounting portion 54 of the first support portion 42 is fixed to this wire 53.

A hook 55 is horizontally fixed to the mounting portion 54. The first bottle 44 is hung on the hook 55. As shown in FIG. 3, a groove 59 is formed in the column 41 in the length direction, and the hook 55 moves up and down in this groove 59.
