However, in the case of a microscope apparatus that observes a living body as it is, it is necessary to insert the tip of the objective lens into the living body for observation. For this reason, before and after observation, the objective lens needs to be cleaned over a wide range including not only the distal end surface but also the distal end portion.
In addition, if the tip of the objective lens is configured to have a small diameter to observe a living body with less invasiveness, the rigidity against external force decreases, so the tip of the small diameter is used during transportation, storage, disinfection, sterilization, or handling. It is also necessary to protect the part from external force.

  The present invention has been made in view of the above-described circumstances, and can clean the objective lens easily and can also protect the objective lens during transportation, storage, or handling. The purpose is to provide ingredients.

In order to achieve the above object, the present invention provides the following means.
The present invention includes a wiping member that is brought into contact with at least the surface of the objective lens and is relatively movable with respect to the objective lens, and that wipes the surface of the objective lens, and the wiping member is attached to the objective lens. And an objective lens cleaning tool including positioning means for positioning.

  According to the present invention, the wiping member is positioned with respect to the objective lens by the operation of the positioning means. In this state, by moving the wiping member relative to the objective lens, the outer surface of the objective lens is wiped by the wiping member while maintaining the relative positional relationship between the wiping member and the outer surface of the objective lens. It will be. As a result, the outer surface of the objective lens can be cleaned without applying an excessive external force to the objective lens by the wiping member.

In the said invention, it is preferable that the said wiping member consists of sponge which impregnated the disinfection liquid or the cleaning liquid.
By doing so, when the wiping member is moved relative to the objective lens, the disinfecting liquid or the cleaning liquid impregnated in the sponge oozes out and the outer surface of the objective lens can be efficiently cleaned.

Moreover, in the said invention, the said wiping member consists of several wiping pieces which can be arrange | positioned adjacent to the circumferential direction of an objective lens, The supporting member which supports each wiping piece, and rocks this supporting member It is good also as providing the hinge member connected so that it is possible.
By comprising in this way, a support member can be rock | fluctuated between the open position which a some wiping piece leaves | separates mutually, and the close position which mutually adjoins by the action | operation of a hinge member. Therefore, by placing the support member in the open position, the objective lens can be easily inserted between the mounting pieces, and by placing the support member in the closed position, the objective lens is surrounded by a plurality of wiping pieces. Can do. Then, the outer surface of the objective lens can be easily cleaned over the entire circumference by moving the wiping member relative to the objective lens while surrounding the objective lens with a plurality of wiping pieces. Become.

  In the above invention, the positioning means includes a recess provided on the wiping piece and having an inner diameter that is substantially complementary to the outer diameter of the objective lens and slightly smaller than the outer diameter of the objective lens. It is good.

  With this configuration, when the objective lens is disposed in the concave portion, the inner surface of the concave portion is slightly deformed to accommodate the objective lens. At this time, the concave portion applies a substantially uniform pressing force over the entire outer surface of the objective lens, and is positioned at a position where the pressing force is balanced. When the wiping piece is impregnated with a disinfecting liquid or the like, the outer surface of the objective lens is efficiently cleaned with the disinfecting liquid or the like that has exuded due to deformation.

  In the above invention, the positioning means is fixed to an objective lens or a microscope main body to which the objective lens is attached, and includes a fixing portion having a ring-shaped guide portion centered on the axis of the objective lens, and a guide for the fixing portion. It is good also as a movable part fitted to a part so that relative rotation is possible, and the said wiping member being attached to the said movable part.

  By fitting the movable part to the guide part of the fixed part fixed to the objective lens, the wiping member attached to the movable part can be positioned with respect to the objective lens. Then, by relatively moving the movable portion using the guide portion as a guide, the wiping member is relatively moved while maintaining a certain positional relationship with respect to the objective lens. Therefore, it is possible to more reliably prevent an excessive external force from being applied to the objective lens, and it is possible to easily clean the outer surface of the objective lens.

  According to the present invention, the objective lens can be easily cleaned, and the objective lens can be protected during transportation, storage, or handling.

Hereinafter, an objective lens cleaning tool according to a first embodiment of the present invention will be described with reference to FIGS.
The objective lens cleaning tool 1 according to the present embodiment cleans the outer surface of the objective lens 2 (see FIG. 2) attached to a microscope main body (not shown), for example, as shown in FIG. Further, a wiping member 3 that is brought into contact with the objective lens 2 is provided.

The wiping member 3 is made of a sponge and has two wiping pieces each having a shape in which a rectangular parallelepiped block having a size capable of accommodating almost the entire objective lens 2 is divided into two by a plane passing through the central axis of the objective lens 2. It is comprised by 3A, 3B.
As shown in FIG. 1, each of the wiping pieces 3A and 3B is substantially complementary to the outer shape of the objective lens 2 when the mating surfaces are aligned with the mating surfaces of the wiping pieces 3A and 3B. Concave portions 4A and 4B are provided.

  The dimensions of the recesses 4A and 4B formed in the wiping pieces 3A and 3B are slightly smaller than the outer dimensions of the objective lens 2. Thereby, by disposing the objective lens 2 along the recesses 4A and 4B, the wiping pieces 3A and 3B are slightly compressed by the objective lens 2 and elastically deformed so that the recesses 4A and 4B are slightly expanded. The elastic pieces are pressed against the outer surface of the objective lens 2, and the wiping pieces 3 </ b> A and 3 </ b> B are arranged in a positioning state with respect to the objective lens 2. That is, the positioning means 4 is constituted by the recesses 4A and 4B.

  The wiping pieces 3A and 3B are impregnated with a disinfectant or cleaning liquid such as alcohol ethanol, aldehyde glutarar, phthalal, peracetic acid, hydrogen peroxide, chlorine dioxide, or the like.

  The two wiping pieces 3A and 3B are supported by the two support members 5A and 5B, respectively. The supporting members 5A and 5B are constituted by thin plate members that cover the four surfaces of the wiping pieces 3A and 3B excluding the mating surfaces of the wiping pieces 3A and 3B and the surface through which the objective lens 2 penetrates. .

  Further, the two support members 5A and 5B are connected to each other by a hinge member 6 so as to be swingable. Accordingly, when the two support members 5A and 5B are brought close to a position (closed position) where the mating surfaces of the two wiping pieces 3A and 3B coincide with each other by the operation of the hinge member 6, the wiping member 3 It is formed in a box shape covering.

Accordingly, when the supporting members 5A and 5B are swung to the closed position by the hinge member 6, the supporting members 5A and 5B are closed and the internal wiping pieces 3A and 3B come close to each other, and both wiping pieces 3A , 3B are combined to form a hole having a shape substantially complementary to the outer shape of the objective lens 2.
Further, when the two support members 5A and 5B are arranged at positions (open positions) that are separated from each other by the operation of the hinge member 6, the inner wiping pieces 3A and 3B are exposed to be opened. It is like that.

The operation of the objective lens cleaning tool 1 according to this embodiment configured as described above will be described below.
In order to clean the outer surface of the objective lens 2 using the objective lens cleaning tool 1 according to the present embodiment, as shown in FIG. 1, the two support members 5A and 5B are swung to the open position by the hinge member 6. By moving, the wiping pieces 3A and 3B supported by the supporting members 5A and 5B are exposed. Then, as shown in FIG. 2, the concave portions 4A and 4B of the exposed wiping piece 3A (or wiping piece 3B) are arranged to face the side surface of the objective lens 2 attached to the microscope body. In this state, the operation of the hinge member 6 causes the two support members 5A and 5B to swing to the closed position. Thereby, as FIG. 3 shows, the objective lens 2 is pinched | interposed by wiping piece 3A, 3B from the both sides of a radial direction.

  As shown in FIG. 4, the recesses 4A and 4B of the wiping pieces 3A and 3B are formed slightly smaller than the outer dimensions of the objective lens 2, so that the objective lens 2 is sandwiched between the wiping pieces 3A and 3B. When pressed, the wiping pieces 3A and 3B are elastically deformed and pressed against the outer surface of the objective lens 2 by the elastic force. Since the wiping pieces 3A and 3B are made of sponge and impregnated with a disinfectant or a cleaning liquid, the disinfecting liquid or the cleaning liquid is oozed out by being pressed.

  In this state, the objective lens cleaning tool 1 is moved relative to the objective lens 2 so as to rotate around the axis of the objective lens 2. As a result, the wiping pieces 3A and 3B are pressed against the outer surface of the objective lens 2 with a predetermined pressing force, and are moved relative to the outer surface of the objective lens 2 in a state where the disinfecting liquid or the cleaning liquid has oozed out. The dirt adhering to the outer surface of the objective lens 2 is wiped off by the wiping pieces 3A and 3B.

  In this case, according to the objective lens cleaning tool 1 according to the present embodiment, there is an advantage that the entire outer surface of the objective lens 2 can be easily wiped by simply rotating it relative to the objective lens 2. Further, in this case, since the objective lens 2 and the wiping pieces 3A, 3B are maintained in a fixed positional relationship by the recesses 4A, 4B provided in the wiping pieces 3A, 3B, it is excessive with respect to the objective lens 2. As shown in FIG. 2, it is possible to prevent the small-diameter tip 2a from being damaged by the external force even if the objective lens 2 has the thin-tip tip 2a at the tip as shown in FIG.

  In the present embodiment, the wiping pieces 3A and 3B are divided into two, and the objective lens 2 is placed along the concave portion 4A (or the concave portion 4B) of one wiping piece 3A (or the wiping piece 3B). After the arrangement, the wiping pieces 3A and 3B are arranged on the entire circumference of the objective lens 2 by sandwiching the objective lens 2 between the two wiping pieces 3A and 3B. Instead of this, for example, FIG. As shown, the wiping member 3 made of a single sponge having a hole (positioning means) 7 into which the objective lens 2 can be inserted may be employed. By doing so, the wiping piece 3 can be brought into contact with the entire circumference of the objective lens 2 by inserting the objective lens 2 into the hole 7 of the wiping piece 3 from the tip. In this case, the hinge member 6 of the support members 5A and 5B is used to open and close the support members 5A and 5B when the wiping piece 3 is attached to and detached from the support members 5A and 5B. Moreover, by using such a single wiping piece 3, for example, as shown in FIG. 6, a disposable article in which a disinfectant or a cleaning liquid is impregnated in advance is enclosed in the bag 8. Is also possible.

Next, an objective lens cleaning tool 10 according to a second embodiment of the present invention will be described below with reference to FIGS.
In description of this embodiment, the same code | symbol is attached | subjected to the location which has the same structure as the objective lens cleaning tool 1 which concerns on 1st Embodiment mentioned above, and description is abbreviate | omitted.

  As shown in FIGS. 7 and 8, the objective lens cleaning tool 10 according to this embodiment includes an objective lens protector 11 attached to the objective lens 2 removed from the microscope main body, and an objective lens protector 11 as a guide. And a fitting member 13 to which a wiping member 12 that is moved relative to the lens 2 is attached.

  As shown in FIG. 8, the objective lens protector 11 is configured by connecting a ring-shaped attachment portion 14 and a ring-shaped seat portion 15 by three columnar portions 16. As shown in FIG. 7, the mounting portion 14 has a central hole 17 that accommodates the large-diameter portion 2 b of the objective lens 2 and a stepped portion that abuts the end surface 2 c on the distal end side of the large-diameter portion 2 b of the objective lens 2. 18, a cutout portion 19 formed by cutting out a part in the circumferential direction, and a push screw 20 provided to be able to advance and retreat in the radial direction. In the figure, reference numeral 21 denotes a mounting screw provided on the objective lens 2 for mounting on the microscope body 24.

  As shown in FIG. 7, the distance between the mounting portion 14 and the seat portion 15 is such that the end surface 2c of the large-diameter portion 2b of the objective lens 2 is in contact with the step portion 18 and the object lens 2 is thin. The diameter tip portion 2 b is set so as to be arranged inside the attachment portion 14 and the seat portion 15. When the objective lens 2 is attached to the attachment portion 14 in a state where the end surface 2c of the large diameter portion 2b is abutted against the step portion 18, the center of the objective lens 2 is disposed at a substantially central position of the objective lens protector 11. It is like that.

Further, the columnar portion 16 is disposed at a sufficient distance outward in the radial direction with respect to the objective lens 2 disposed at a substantially central position of the objective lens protector 11. Thereby, when the objective lens protector 11 is gripped by hand from the outside, it is set so that the hand does not touch the outer surface of the objective lens 25 arranged at the center position.
In addition, a gap 22 is provided between the columnar portions 16 so that the state of the internal objective lens 2 can be visually confirmed or cleaned from the outside.

  As shown in FIG. 8, the notch 19 has a width that is wider than the diameter of the intermediate position in the longitudinal direction of the objective lens 2. Accordingly, when the objective lens protector 11 is attached to and detached from the objective lens 2, it is not necessary to insert / remove the objective lens protector 11 in the optical axis direction from the small-diameter tip 2a side of the objective lens 2, as shown in FIG. As shown in the figure, the intermediate position in the longitudinal direction of the objective lens 2 can be passed through the cutout portion 19 so as to be inserted and removed in the radial direction.

  The push screw 20 is tightened in a state where the end surface 2c of the large diameter portion 2b is abutted against the stepped portion 18 of the mounting portion 14, so that the outer peripheral surface of the large diameter portion 2b is radially inward by the tip. Press toward. Thereby, the objective lens 2 and the objective lens protector 11 are fixed to each other so as not to move relative to each other in the circumferential direction and the axial direction due to friction between them.

Moreover, the ring-shaped seat part 15 is provided with the fitting hole 15a which fits the said fitting member 13 in the internal diameter side, and the abutting surface 15b which abuts the fitting member 13 to an axial direction.
The fitting member 13 includes a fitting shaft portion 13a fitted into the fitting hole 15a of the seat portion 15 of the objective lens protector 11 with a minute gap, a step portion 13b abutted against the abutting surface 15b, When the stepped portion 13b is abutted against the abutting surface 15b, there is provided a wiping shaft portion 13c that is disposed to face the front end surface of the objective lens 2 with a minute gap.

Further, the fitting member 13 is covered with a wiping member 12 such as sylbon paper impregnated with an antiseptic solution such as alcohol, and the ring member is fitted to the wiping shaft portion 13c. The pressing member 23 holds the tip of the wiping shaft portion 13c.
Thereby, when the fitting member 13 is fitted into the fitting hole 15a of the seat portion 15 of the objective lens protector 11 and is abutted against the abutting surface 15b of the seat portion 15, it is attached to the tip of the wiping shaft portion 13c. The wiping member 12 is brought into contact with the tip of the objective lens 2.

The operation of the objective lens cleaning tool 10 according to the present embodiment configured as described above will be described below.
In order to clean the objective lens 2 using the objective lens cleaning tool 10 according to the present embodiment, first, in the state where the push screw 20 provided in the attachment portion 14 is sufficiently retracted radially outward, the attachment portion The large-diameter portion 2 b of the objective lens 2 is inserted into the center hole 17 of 14, and the end surface 2 c of the large-diameter portion 2 b of the objective lens 2 is abutted against the step portion 18 of the mounting portion 14. In this state, the objective lens 2 is positioned at a substantially central position of the three columnar portions 16, and unless the finger is intentionally inserted into the gap between the columnar portions 16, the objective lens 2 is manually applied to the outer surface of the objective lens 2 from the outside. It becomes difficult to touch with.

  Next, when the push screw 20 is operated and narrowed inward in the radial direction, the distal end of the push screw 20 moves the outer peripheral surface of the large-diameter portion 2b of the objective lens 2 accommodated in the central hole 17 in the radial direction. Press toward. Thereby, the objective lens 2 rotates in the circumferential direction in the objective lens protector 11 or falls off in the axial direction by the frictional force generated between the tip of the push screw 20 and the outer peripheral surface of the large diameter portion 2b. Not to be fixed.

  By fixing the objective lens 2, the objective lens protector 11 according to the present embodiment can prevent external force from being applied to the small-diameter tip 2a of the objective lens 2 and protect it from being damaged. Therefore, by carrying, storing or assembling with the objective lens protector 11 attached, the objective lens 2 can be protected from external force during conveyance, storage or assembling, and its soundness can be maintained.

  Further, when the objective lens 2 is in a dirty state after use, it is possible to handle the objective lens 2 without directly touching the objective lens 2 by attaching the objective lens protector 11. Therefore, it is possible to prevent dirt on the objective lens 2 from adhering to the hand.

For example, when a microscope observation is performed with the objective lens 2 attached to the microscope main body 24 and a body fluid or protein of a specimen (not shown) adheres to the small-diameter tip 2 a of the objective lens 2, The objective lens protector 11 is attached to the objective lens 2 in the attached state.
In this case, as shown in FIG. 9, the objective lens protector 11 is inserted into the objective lens 2 in the radial direction by passing a midway position in the longitudinal direction of the objective lens 2 through the notch 19 of the mounting portion 14. be able to. Therefore, the objective lens protector 11 can be attached to the objective lens 2 even when a sufficient working space larger than the total length of the objective lens protector 11 cannot be secured around the objective lens 2 attached to the microscope body 24.

Since the objective lens 2 is locked so as not to move relative to the objective lens protector 11 by the operation of the push screw 20, the operator rotates the objective lens protector 11 around the optical axis of the objective lens 2. Thus, the objective lens 2 can be easily detached from the microscope body 24.
At this time, since the operator operates the objective lens protector 11, it is not necessary to directly touch the surface of the objective lens 2 with a hand, and the occurrence of inconvenience that the dirt attached to the objective lens 2 adheres to the hand is prevented. it can. Further, since the objective lens protector 11 having an outer diameter larger than that of the large diameter portion 2b of the objective lens 2 is rotated, less force is required for the rotation, and the detaching operation can be easily performed.

  Further, when the objective lens 2 is in a clean state before use, the objective lens 2 can be handled without touching the objective lens 2 directly by attaching the objective lens protector 11. Therefore, it is possible to prevent hand dirt from adhering to the clean objective lens 2.

  For example, when the objective lens 2 is attached to the microscope main body 24 in a cleaned, disinfected or sterilized state, the objective lens protector 11 is operated so that the objective lens 2 is not directly touched. Therefore, the outer surface of the objective lens 2 that has been sterilized can be prevented from being soiled by hand stains, and the next microscope observation can be performed while the surface is kept clean. Further, even when the objective lens 2 is attached to the microscope body 24, the work space around the objective lens 2 can be reduced.

  In this state, in order to clean the tip of the objective lens 2, the wiping shaft portion 13 c of the fitting member 13 is covered with a wiping member 12 such as sylbon paper soaked with a disinfecting solution, and then wiped from above. The presser member 23 is fitted to the take-off shaft portion 13c so that the wiping member 12 is stretched at the tip of the wiping shaft portion 13c. The fitting shaft portion 13a of the fitting member 13 thus configured is fitted into the fitting hole 15a of the seat portion 15 provided in the objective lens protector 11, and the step portion 13b of the fitting member 13 is seated. The wiping member 12 is brought into contact with the tip of the objective lens 2 with an appropriate pressing force by inserting until it hits the 15 abutting surface 15b. In this state, the fitting member 13 is rotated around the axis of the objective lens 2 with respect to the objective lens protector 11 to move the wiping member 12 relative to the objective lens 2 and wipe the tip of the objective lens 2. Can do.

  Therefore, the operator can cleanly clean the tip of the objective lens 2 simply by rotating the fitting member 13 with respect to the objective lens protector 11. In this case, since the step portion 13b of the fitting member 13 is abutted against the abutting surface 15b of the seat portion 15 of the objective lens protector 11, the objective lens 2 can be operated even if the operator operates the fitting member 13 by hand. The objective lens 2 can be protected without applying an excessive force to the tip surface of the lens.

  Then, after the cleaning is completed, the wiping member 12 with dirt can be removed and replaced by simply removing the fitting member 13 from the objective lens protector 11 and removing the pressing member 23 from the wiping shaft portion 13c. Become. Therefore, it is possible to sequentially clean the plurality of objective lenses 2 by reusing the fitting member 13 and the pressing member 23 by appropriately replacing the wiping member 12 as disposable.

In the present embodiment, the wiping member 12 is sylbon paper impregnated with a disinfectant, but instead of this, other wiping members such as gauze and paper may be attached.
Moreover, although what fixed to the objective lens 2 was illustrated as the objective lens protector 11, it may replace with this and the thing of the structure fixed to the microscope main body 24 of the state which fixed the objective lens 2 may be employ | adopted.

Next, an objective lens cleaning tool 30 according to a third embodiment of the present invention will be described below with reference to FIGS.
In the description of the present embodiment, the same reference numerals are given to portions having the same configuration as the objective lens cleaning tool 10 according to the second embodiment described above, and the description thereof is omitted.

The objective lens cleaning tool 30 according to the present embodiment is different from the objective lens cleaning tool 10 according to the second embodiment in the fitting member 31, as shown in FIG.
The fitting member 31 includes a fitting shaft portion 31a fitted with a small gap in the fitting hole 15a of the seat portion 15 of the objective lens protector 11, and a step portion 31b abutted against the abutting surface 15b. And a housing portion 31c for housing a wiping member 32 made of a sponge that is opposed to the small-diameter tip portion 2a of the objective lens 2 when the fitting shaft portion 31a is fitted into the fitting hole 15a. .

The accommodating portion 31c accommodates a wiping member 32 impregnated with a disinfecting liquid or a cleaning liquid, and holds the impregnated disinfecting liquid so that it does not spill. Moreover, the accommodating part 31c is provided with the opening part which exposes the upper surface of the accommodated wiping member 32. As shown in FIG.
Then, in a state where the wiping member 32 is housed in the housing portion 31 c, the fitting member 31 is fitted into the fitting hole 15 a of the objective lens protector 11, and the step portion 31 b of the fitting member 31 is formed on the objective lens protector 11. When the contact is made until it comes into contact with the contact surface 15b, as shown in FIG. 11, the small-diameter tip 2a of the objective lens 2 is inserted into the wiping member 32 stored in the storage 31c. . Thereby, the tip of the small-diameter tip 2a of the objective lens 2 is inserted into the wiping member 32 and is pressed from the wiping member 32 with a predetermined contact pressure.

  According to the objective lens cleaning tool 30 according to the present embodiment configured as described above, the fitting member 31 is fitted into the fitting hole 15a of the objective lens protector 11 in a state where the objective lens 2 is attached to the objective lens protector 11. The shaft portion 31a is fitted, and the fitting proceeds as it is. Thereby, the small diameter front-end | tip part 2a can be stabbed in the wiping member 32 accommodated in the accommodating part 31c of the fitting member 31. FIG. In this state, by rotating the fitting member 31 relative to the objective lens protector 11 around the axis of the objective lens 2, the outer surface of the small-diameter distal end portion 2 a of the objective lens 2 is entirely rotated by the wiping member 32. Can be easily cleaned over.

  In this case, since the small-diameter tip 2a of the objective lens 2 is inserted into the wiping member 32 with the fitting shaft portion 31a fitted in the fitting hole 15a, the wiping member 32 at the time of insertion is inserted. Relative movement with respect to the objective lens 2 is guided parallel to the axial direction of the objective lens 2. Therefore, an external force does not act on the objective lens 2 in the direction intersecting the axial direction at the time of insertion.

  Further, when cleaning the outer surface of the objective lens 2, the fitting member 31 is rotated relative to the objective lens protector 11 while the fitting shaft portion 31a is fitted in the fitting hole 15a. There is no misalignment between the member 31 and the small-diameter tip 2a of the objective lens 2, and no external force acts on the small-diameter tip 2a in the direction intersecting the axial direction even during relative rotation. Therefore, the objective lens 2 is not damaged by the external force.

  Further, since the wiping member 32 is pressed over the entire circumference of the outer surface of the small-diameter tip 2a of the objective lens 2, simply rotating the fitting member 31 relative to the objective lens protector 11 makes it easy to remove the objective lens 2. The dirt on the outer surface can be wiped off and cleaned.

  Also in this embodiment, as shown in FIG. 12, a sponge impregnated with a disinfectant or a cleaning liquid is sealed in the bag 33 as the wiping member 32 accommodated in the accommodating portion 31c of the fitting member 31. It is good also as preparing as a disposable item.
