Description

The present invention relates to an automatic cleaning apparatus that is mainly applicable to handpieces of ophthalmic surgical instruments and can be applied to other medical surgical instruments.

Here, a handpiece is taken as an example. Conventionally, after washing the inside of the cylinder of the handpiece, suction liquid is sucked with a syringe, and press-fitting and discharge are repeated. In addition, clogging and dirt in the tip are discharged with a compressor. Has improved.

Blood, fat, protein, cortex, etc. are clogged in the handpiece cylinder and tip cylinder after surgery, and blood, fat, protein, cortex, etc. are clogged in the handpiece cylinder and tip cylinder after surgery. Cleaning is essential.

Next, an ophthalmic surgical instrument, a diamond knife, an I / A handpiece, etc. are put in a cassette case and sterilized with pressure and high-temperature steam in an autoclave (sterilizer).

Problems to be solved by the invention

For ophthalmic surgery, very delicate and clean instruments are required. For example, there is a suction port of 0,3 mm next to the tip of the tube and it is very small, so it is easy to clog. In addition to being clogged, the functioning of the instrument is not only impaired, but the completeness of the operation is also at risk.

In addition, the price per chip is around 50,000 yen, and if the U / S handpiece is old, the price is 1.5 million yen per chip, which makes it difficult to buy. Therefore, it is desired to perform reliable and complete cleaning with this cleaning apparatus.

Means for solving the problem

Therefore, in this cleaning device, the handpiece is placed on a mounting base, and is fixed with a pressing plate having a number T on one side from the top, and with a hook.
First, the vacuum pump is activated by first inserting and switching the vacuum pump tube into the convex pipe of the handpiece leading to the tip.

It is assumed that blood, protein, fat, cortex and the like are dried and solidified in the tip as time passes after the operation, and the tip is first removed by suction.

If the air pump is suddenly pumped before sucking with the vacuum pump, the hole at the tip of the tip is small, so if you continue to pump forcibly forcibly, the tip hole may be deformed and the joint seal may be damaged. Because there is, suction is performed first for that purpose.

Next, the air pump is flushed several times through the three-way valve by an air pump or through the port to the handpiece.

Then, the prepared cleaning liquid is flushed to the handpiece by a tube pump through a three-way valve like an air pump.

This operation of the air pump and tube pump is repeated several times, and finally the air pulse flush is completed.

Through the operation of the series of cleaning systems as described above, the objective can be achieved accurately and completely.

The invention's effect

As described above in detail, according to the present invention, foreign matter at the tip of the tip (2) is not clogged by suction of the vacuum pump (5), the tip (2) has a long service life, the cleaning liquid is wrong, and waste is lost. Don't make it.

In addition, the downsizing and structural simplification of the device in the future can reduce the cost of manufacturing and the device.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, a handpiece (1) cleaning apparatus according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a schematic view showing a handpiece (1) cleaning apparatus according to the present invention. FIG. 2 is a schematic view showing the whole handpiece cleaning apparatus according to the present invention. FIG. 3 is a sectional view showing the presser of the handpiece (1) according to the present invention.

Hereinafter, the results of tests conducted to verify the effects of the present invention will be specifically described. A test was performed to compare the cleaning power with a conventional cleaning using a handpiece cleaning device.

A series of operations in conventional hand washing is routinely ruined, and since it can be done easily, there is a possibility that filth will remain in the handpiece (1) and the tip (2), and the instrument will fall from the hand. And may be damaged.

It was confirmed that the handpiece (1) was completely cleaned by using an automatic cleaning device, and that it was more completely cleaned by increasing the number of times.

As described above in detail, according to the present development, the suction of the vacuum pump (5) does not clog the tip (2), and it does not give a long life, and the cleaning liquid is not mistaken or wasted. .

Particularly in the field of ophthalmology, it is absolutely necessary for cleaning and sterilizing handpieces and chips, and for ophthalmic surgical instruments.
