Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lens tray for storing optical lenses used in ophthalmic surgery, in which a precise optical lens must be selected quickly despite many similar shapes.
[0002]
[Prior art]
Many optical lenses used for ophthalmic surgery have various shapes while having the same outer diameter.
For example, a biconvex lens that is convex on both sides, a convex surface that is convex and the other surface is a plano-convex lens, a convex surface that is convex and the other surface is concave, but the radius of the convex surface is the radius of the concave surface The smaller one is a convex meniscus, the one that is co-concave on both sides is a biconcave lens, one surface is flat and the other surface is concave is a plano-concave lens, one surface is convex and the other surface is concave but convex There is a concave meniscus whose radius is larger than the radius of the concave surface.
Conventionally, in order to store optical lenses having various types as described above, containers for storing individual lenses are mainly used.
[0003]
[Problems to be solved by the invention]
However, since a plurality of optical lenses are appropriately exchanged during surgery, it is preferable that the plurality of optical lenses can be stored in one container.
FIG. 14 shows a rubber general-purpose tray 8 for storing a small medical instrument.
For example, when a plurality of optical lenses are stored using the general-purpose tray 8, the tray is simply provided with a projection, and the optical lens is only stored between the projections. This may cause another lens to be accidentally removed when the lens is removed, and it does not have a storage part for storing the lens at a predetermined position. In some cases, the lenses may come into contact with each other, and the mutual lenses may be lost. Further, the general-purpose tray 8 simply having protrusions is not preferable in appearance.

6 to 13 are a perspective view, a top view, and a cross-sectional view schematically showing lens trays 4 to 7 according to different embodiments of the present invention. These lens trays 4 to 7 will be described after the description of the lens tray 1.
FIG. 14 is a perspective view showing an example of a conventional general-purpose tray 8 as described in [Problems to be Solved by the Invention].
1 to 3, the lens tray 1 is integrally formed of a material to be described later, and a cylindrical portion (hereinafter referred to as a “cylindrical portion”) 12 that houses two or more optical lenses, and an optical lens-related component. It has an accessory storage recess (hereinafter referred to as “storage recess”) 13 and a lens tray outer wall 19.
And the cylindrical part 12 and the accommodation recessed part 13 have the drain hole 14, Furthermore, the cylindrical part 12 has an internal diameter which adapts the outer diameter of the optical lens 15 accommodated, and the thickness of the cylindrical part bottom part 16 is as follows. As will be described later, the thickness is appropriately set so as to match the thickness of the optical lens 15 accommodated.
Further, in the vicinity of the cylindrical portion 12, there is an inscription 11 obtained by shaping the shape of the optical lens 15 to be accommodated in the cylindrical portion 12, and the optical lens 15 to be accommodated in the cylindrical portion 12 by this inscription 11. It can be easily recognized without error. Further, when taking out, the necessary optical lens 15 can be easily taken out from the shape of the stamp 11. The stamp 11 may be a symbol that is the shape of the optical lens 15 as in the present embodiment, or may be a letter, a number, or the like.
[0014]
The stamp 11 may have a structure that rises from the bottom of the lens tray 1 or may have a structure in which the bottom of the lens tray 1 is carved. Furthermore, in order to make the inscription 11 clearer, it is possible to give the inscription 11 a color different from the color of the lens tray 1.
[0015]
Next, it is also preferable to write a symbol and an alphabet as the inscription 11.
In general, the optical lens 15 is generally provided with a name, a number, and the like. For a user who recognizes the optical lens 15 with the name or the number, such a name or number is engraved on the lens tray. Because it is quite convenient.
For example, during a surgical operation, a doctor selects an optical lens, and a nurse takes out the optical lens from the lens tray according to the selection, and hands it to the doctor. The engraving on the lens tray conveys the doctor's selection accurately and reliably to the nurse. It will be.
Therefore, it is a preferred embodiment to stamp the name and number of the optical lens 15 in the vicinity of the cylindrical portion as such a stamp.
On the other hand, in FIGS. 1 to 3, gaps 17 and 18 are provided between the cylindrical portions and between the cylindrical portion and the lens tray outer wall, respectively.
[0016]
Next, a usage example of the lens tray 1 will be described.
First, the lens tray 1 of the present invention is installed in the lens container 2 shown in FIG. 4, and the optical lens 15 is accommodated in the cylindrical portion 12. Further, according to the shape of the accessory related to the optical lens 15, for example, small parts are stored in the storage recess 13, for example, tweezers are stored in the gap 17 between the cylindrical parts, or the gap 18 between the cylindrical part and the lens tray outer wall. As appropriate, store it.
[0017]
When the optical lens 15 is accommodated, the appropriate optical lens 15 can be easily accommodated in the appropriate cylindrical portion 12 with reference to the marking 11.
In addition, by referring to the stamp 11 when the optical lens 15 is taken out, the necessary optical lens 15 can be easily taken out without error even in a tense situation such as during surgery.
[0018]
When the storage of the optical lens 15 and the like into the lens tray 1 installed in the lens container 2 is completed, the lens container cover 3 shown in FIG.
As described above, the distance between the upper end surface of the optical lens 15 and the cover 3 of the lens container is set by appropriately setting the thickness of the cylindrical portion bottom 16 so as to match the thickness of the optical lens 15 to be accommodated. Can be constant.
By keeping this distance constant, it is possible to prevent damage to the optical lens 15 due to a collision between the upper end surface of the optical lens 15 and the cover 3 of the lens container.
[0019]
In any case, the medical optical lens 15 is made of glass, and there are optical lenses having various shapes as described above. For this reason, some have a structure in which the peripheral portion is easily chipped. Even if the outer circumference is the same, the height of the lens varies depending on the individual because of the difference in shape, and the difference in height is considerable. For this reason, in the case of a lens tray in which all the cylindrical portions have the same depth, when the lens container 2 is transported, the optical lens 15 may move up and down and the edges may be lost.
Therefore, the depth of the cylindrical portion 12 is preferably set to a depth suitable for each lens according to the lens to be accommodated. Further, as described above, when the lens container 2 is transported, the lens container cover 3 and the optical lens are moved when the lens container cover 3 is closed so that the optical lens 15 moves up and down and the edges are not lost. 15 is designed to be constant, and the gap is, for example, 0.1 to 2 mm.
[0020]
Next, since the optical lens 15 as a medical instrument is used in a medical field such as an operating room, it is necessary to sterilize and disinfect prior to use from the viewpoint of infection prevention. From the viewpoint, it is desirable that the optical lens 15 is placed in the lens container 2 and can be sterilized with the cover 3 of the lens container on.
Therefore, the lens tray 1 of the present invention is required to withstand various sterilization conditions (high-pressure steam sterilization, gas sterilization, etc.) used for the optical lens 15. Conditions that can withstand these sterilization conditions include that the material of the lens tray must be heat resistant and not eroded by gas for gas sterilization.
[0021]
As a material suitable for such conditions, silicon rubber is preferable. Silicone rubber is heat resistant, and is physically rubbery and soft, so there is no risk of damage even if it comes into contact with the optical lens 15. Furthermore, it is preferable to use silicon rubber as a constituent material of the lens tray 1 because it has a sufficient track record of use at medical sites.
[0022]
Of course, the constituent material of the lens tray 1 is not limited to silicon rubber, and any material may be used as long as it does not easily deform, such as plastic and metal. In particular, when plastic is used, if the material is softer than the lens, it has the effect of preventing the chipping of the lens as in the case of the silicon rubber described above. Furthermore, various designs can be easily and economically obtained by plastic molding means, and in addition, by molding using colored raw materials, various colors can be easily obtained, which is a preferable material.
[0023]
When high-pressure steam sterilization is used as a sterilization method, a large amount of water that has become steam is cooled after sterilization and remains in the cylindrical portion 12. If the remaining water is left as it is, liquid stain will be produced in the optical lens 15 accommodated in the cylindrical portion 12 when the water is dried. In the case of an optical lens, such a liquid stain is not preferable because it adversely affects its optical characteristics. Therefore, the cylindrical portion 12 is provided with a drain hole 14 for draining residual water during high-pressure steam sterilization.
[0024]
Further, when gas sterilization is used as a sterilization method, the water draining hole 14 becomes a gas passage and the optical lens 15 is effectively sterilized.
The lens container 2 and the cover 3 of the lens container are provided with through holes 21 and 31, respectively, through which steam and gas for gas sterilization flow during sterilization.
[0025]
The sterilized lens container is transported to the operating room and placed on a mounting table for medical instruments.
As the operation progresses, the doctor or nurse appropriately takes out the required optical lens 15 from the lens tray 1 with reference to the stamp 11, and returns it to the lens tray 1 with reference to the stamp 11 again when the use is completed. . At this time, even if an attempt is made to return the optical lens 15 to the wrong cylindrical portion 12, an error can be noticed due to the difference in thickness of the cylindrical portion bottom portion 16. In addition, since the total number of optical lenses 15 can always be confirmed, loss of the optical lenses 15 during surgery can be prevented in advance.
[0026]
When the operation is completed, the cover 3 of the lens container is closed again and taken out from the operating room. After sterilization, the lens container can be stored in this state until the next operation.
[0027]
