Description

  The present invention is a tray on which an ophthalmic instrument used for cataract surgery or the like in ophthalmology is placed, and an ophthalmic cleaning container combined tray that can also be used as a cleaning container that can store and wash the ophthalmic instrument by an automatic cleaning device; The present invention also relates to a cleaning system including a cleaning device that can clean the ophthalmic cleaning container / tray.

  In the medical field, various medical instruments are used when performing surgery or treatment. Among these, in ophthalmology, ophthalmic instruments such as ophthalmic forceps are used when performing cataract surgery, treatment, and the like. This ophthalmic instrument is much more delicate and expensive than a normal medical instrument, and in particular, the tip may be deformed even if a slight impact is applied. Once deformation occurs, the use of the ophthalmic instrument in surgical treatment may cause damage to the patient's eyes, which makes it difficult to reuse.

  By the way, in recent years, in the cleaning of a general medical instrument, a cleaning apparatus using cavitation by ultrasonic waves is generally used. However, the above-described ophthalmic instrument has a drawback that it is likely to be deformed or the like due to a long-term use due to fine scratches caused by ultrasonic cleaning. For this reason, in order to avoid deterioration due to ultrasonic cleaning, cleaning of ophthalmic instruments is often performed by using a cleaning device that does not use ultrasonic waves or by a cleaning operation by hand washing.

  However, it has been difficult to achieve a sufficient cleaning effect with a cleaning apparatus that does not use ultrasonic waves at all. Moreover, the washing operation by hand washing is not only very troublesome, but there is a risk that an expensive ophthalmic instrument may be deformed or damaged by human error.

  On the other hand, when cleaning a medical instrument with a cleaning device, the medical instrument is stored in a predetermined cleaning container having water permeability, and the cleaning container is cleaned with the cleaning apparatus. Such as, for example, a sterilization instrument cassette for use as a sterilization container for medical and dental instruments, in which two trays can be separated and joined, and a sterilization storage cassette (e.g. Patent Document 1) is known.

  Also, as a dental or surgical instrument tray, for example, a pair of opposed upstanding side walls and a rack extending between the side walls to position the instruments in spaced relation to each other A clamp bar hinged to one side wall and a holder for holding a small accessory partly away from the device on a portion of the tray, the holder being attached to the tray The clamp bar is snap-fit and the clamp bar is removably latched on the other side wall and includes an instrument tray (e.g., with latch means for securing the instrument in place in the rack). , See Patent Document 2).
