Problem. Therefore, for example, at the time of implant treatment in dentistry, a plurality of cutting tools are used when opening an implantation hole for implanting an artificial tooth root in the jaw bone, but after using these cutting tools, one by one with gauze. It wraps and immerses it in the cleaning solution in the cleaning tank to protect the blade by ultrasonic cleaning while avoiding direct contact between the cutting tools.
[0005]
However, if the cutting tool is immersed in gauze instead of being immersed in the cleaning solution as described above, the cleaning efficiency may be reduced by that amount, and a large amount of gauze preparation or gauze contamination may occur. Consideration must also be given to prevention.
[0006]
In addition, the work of wrapping small cutting tools with gauze one by one takes time and effort, and there is a high possibility that the degree of cleaning will vary depending on the way the worker wraps. It is hard to say that it can be expected.
[0007]
Furthermore, if the cutting tool removed from the cleaning tank after ultrasonic cleaning is left as it is, the cutting tool will be rusted and unusable.In the past, the air attached to the cutting tool was wiped off with a cloth and air blown. The tool was dried and stored in a desiccator. However, such work is troublesome and time-consuming and inconvenient.In addition, some workers may end the work without completely wiping the cleaning liquid attached to the cutting tool, thereby improving the cleaning efficiency and cleaning accuracy. Was in the way.

In addition, when the cleaning stand holds the plurality of cutting tools in a circular shape or concentric shape, when the cleaning tool is mounted on the cleaning liquid removing device and rotates, the rotation balance can be improved.
[0020]
According to the fourth aspect of the present invention, since the shaft that protrudes above the upper plate through the center of the upper plate is provided, the cleaning liquid in the cleaning tank is prevented from immersing the upper portion of the shaft in the cleaning liquid. If the amount is adjusted, the operator's hands may be contaminated by the cleaning liquid or contaminated by the cleaning liquid by grasping the upper part of the shaft and putting the cleaning stand in or out of the cleaning liquid. This can be easily prevented.
In addition, since the shaft and the rotating shaft have a D-cut cross section, the rotational force of the rotating shaft is reliably transmitted to the shaft, causing slippage between the rotating shaft and the shaft, causing the shafts to move, Is prevented from slipping.
[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0024]
The dental cutting tool cleaning device according to the present embodiment includes a cleaning stand and a cleaning liquid removing device.
FIG. 1 shows a cleaning stand according to the present embodiment. The stand 1 is roughly constituted by three holding plates 2a, 2b, 2c, a bottom plate 3, a shaft 4, and three pillars 5. The stand 1 can hold a cutting tool for implant treatment used in dentistry as described later, and is installed in a cleaning tank of an ultrasonic cleaning machine while holding the cutting tool, so that the cutting tool has Enables sonic cleaning.
[0025]
Here, the cutting tool for implant treatment is a cutting tool with a blade, such as a drill, for drilling an implantation hole for implanting an artificial tooth root in the jaw bone, and is detachably attached to a dedicated handpiece as an implant treatment tool. It is attached. FIG. 2 shows a cutting tool to be cleaned in the present embodiment. The cutting tool 10a includes a blade portion 11a having a cutting function and a mounting portion 12a for mounting to a handpiece. A step 13a is formed between the step 13a and the step 12a. Both the mounting portion 12a and the step portion 13a have a substantially round bar shape, and the diameter D _13a of the step portion 13a is larger than the diameter D _{12a of the} mounting portion 12a.
[0026]
Also in the cutting tool 10b, the blade part 11b and the mounting part 12b are connected by the step part 13b, and the diameter D _13b of the step part 13b is larger than the diameter D _{12b of the} mounting part 12b. Further, in comparison with the cutting tool 10a, the length _{L 12b} of the mounting portion 12b of the cutting tool 10b is larger than the length _{L 12a} of the mounting portion 12a of the cutting tool 10a.
[0027]
The cutting tool 10c does not have a step like the cutting tool 10a and the cutting tool 10b, and the blade 11c and the mounting portion 12c having substantially the same diameter are formed continuously.
[0028]
As shown in FIGS. 3 and 4, the holding plates 2a, 2b, 2c and the bottom plate 3 of the stand 1 are hard resin disks having substantially the same diameter. The holding plates 2a, 2b, 2c and the bottom plate 3 are supported so as to be parallel to each other by a shaft 4 penetrating the center thereof and a pillar 5 penetrating the outer edge thereof.
[0029]
Specifically, a screw surface is formed on the outer periphery of the pillar 5, and each pillar 5 is formed at a position that divides the outer edges of the holding plates 2 a, 2 b, 2 c and the bottom plate 3 into three equal parts along the circumferential direction. The holding plates 2a, 2b, 2c and the bottom plate 3 are sandwiched and supported by a nut 7 screwed to the screw surface while penetrating the through hole. The shaft 4 is hollow and presents a D-shaped cross section in which a part of the side surface is flattened, and penetrates a D-shaped through hole formed in the center of the holding plates 2a, 2b, 2c and the bottom plate 3. Then, it is fixed to each plate by a fixing bracket not shown.
[0030]
The holding plates 2a, 2b, 2c are arranged in this order from above, and the bottom plate 3 is arranged below the lowermost holding plate 2c. Distance _{L 1} between the holding plate 2a and the holding plate 2b is slightly shorter than the length _{L 12a,} between the holding plate 2a and the holding plate 2c distance _{L 2} is slightly larger than the length _{L 12b} short distance L ₃ between the holding plate 2a and the bottom plate 3 is set longer than the length L _12b. The shaft 4 protrudes more remarkably upward from the holding plate 2 a than the pillar 5, and the pillar 5 protrudes downward from the bottom plate 3 than the shaft 4. The lower end of each pedestal 5 is attached to a leg 8 to which a rubber foot is attached to support the entire stand 1, and the upper end of the shaft 4 is a gripper 9 used when the operator of the cutting tool cleans the stand 1. It has become.
[0031]
Holding plate 2a, 2b, the 2c, the shaft 4 a plurality of insertion holes 6 while maintaining a predetermined distance on the two virtual concentric S _1, S ₂ centered on are formed (hereinafter, the insertion hole In order to discriminate which holding plate is formed on the holding plate 6, the insertion hole 6 formed on the holding plate 2 a is inserted through the insertion hole 6 a, and the insertion hole 6 formed on the holding plate 2 b is inserted through the insertion hole 6 b. The insertion hole 6 formed in the holding plate 2c is also referred to as an insertion hole 6c.) The diameter D of each insertion hole 6 is larger than the largest one of the diameters D _12a , D _12b , D _12c of the mounting portions 12a, 12b, 12c of the cutting tools 10a, 10b, 10c, and the step of the cutting tools 10a, 10b. The diameters D _13a and D _13b of the portions 13a and 13b are smaller than the smaller ones. Each of the insertion holes 6b, 6c formed in the holding plates 2b, 2c is located below the corresponding one of the plurality of insertion holes 6a formed in the holding plate 6a, and corresponds to each of the plates. The insertion holes 6a, 6b, 6c are arranged coaxially (on the same vertical line). The insertion holes 6b and 6c formed in the holding plates 2b and 2c function as receiving holes in some cases, but this point will be described later.
[0032]
To perform ultrasonic cleaning of the cutting tools 10a, 10b, and 10c using the stand 1, the operator inserts the cutting tool 10a into the insertion holes 6a and 6b from above the holding plate 2a with the mounting portion 12a facing downward. . In this case, the diameter D of the insertion hole 6a satisfies _D 12a _{<D <D 13a,} the length _{L 12a} of the mounting portion 12a satisfies _{L 1 <L 12a <L 2} ( see FIG. 4), the cutting tool 10a The step portion 13a and the blade portion 11a do not pass through the insertion hole 6a and are caught on the peripheral edge portion 6a ', and are locked and held by the peripheral edge portion 6a'. The lower portion of the cutting tool 10a (the end of the mounting portion 12a) enters the insertion hole 6b, and if the cutting tool 10a swings, it is received by the peripheral surface 6b 'of the insertion hole 6b as a receiving hole. , So that it does not interfere with other cutting tools or members.
[0033]
Similarly, the worker inserts the cutting tool 10b into the other insertion holes 6a, 6b, and 6c with the mounting portion 12b facing downward. In this case, the length L _12b of the mounting portion _12b is L ₂ <L _12b <. since satisfy L _3, (the end of the mounting portion 12b) lower portion of the cutting tool 10b is received on the peripheral surface 6c 'of the insertion hole 6c of the receiving hole.
[0034]
On the other hand, if the mounting portion 12b of the cutting tool 10b is longer and L ₃ <L _12b is satisfied, or if the diameter is smaller than the diameter D of the insertion hole 6 over the entire length as in the cutting tool 10c, cutting is performed. The lower end of the tool reaches the bottom plate 3 without being held by the peripheral edge 6a 'of the insertion hole 6a. As for the cutting tool 10c, the lower end of the mounting portion 12c is supported by the bottom plate 3 from below, and the mounting portion 12c and the blade portion 11c are held from the side by the peripheral surface of the insertion hole 6b or the insertion hole 6a. Is held in a state of leaning against the insertion hole 6.
[0035]
When the stand 1 holds the cutting tools 10a, 10b, and 10c, the operator then places the stand 1 on the bottom surface 20a (see FIG. 5) of the container 20 containing the disinfecting solution, and the cutting tools 10a, 10b. , 10c are immersed in a disinfectant solution. Since the container 20 is provided with the handle 21, the operator may grasp the handle 21 and put the stand 1 together with the container 20 into the cleaning tank 23 of the ultrasonic cleaner 22. The washing tank 23 is filled with water in advance, but the water level is such that when the container 20 is put into the inside of the washing tank 23, the water in the washing tank 23 flows over the peripheral wall 20b of the container 20 and becomes a disinfecting solution. It is set not to be mixed.
[0036]
Subsequently, the operator turns on the switch 24 of the ultrasonic cleaner 22, whereby the ultrasonic vibration applied to the water in the cleaning tank 23 is transmitted to the disinfectant via the peripheral wall 20 b of the container 20, and is transmitted to the stand 1. The held cutting tools 10a, 10b, 10c are ultrasonically cleaned.
[0037]
In the cleaning stand 1 according to this embodiment, the cutting tools 10a, 10b, and 10c are held in any or all of the insertion holes 6a, 6b, and 6c, and are immersed in the cleaning liquid in the container 20 to perform cleaning. The contact and collision with other cleaning objects and the like in the above are avoided. That is, the cutting tools 10a, 10b, and 10c are individually wrapped with a buffer material such as gauze or the like, and are only held on the stand 1, thereby preventing breakage or damage of the blades of each cutting tool. Time and cost of consumables such as gauze can be greatly reduced. Further, since the cleaning liquid directly hits the cutting tools 10a, 10b, and 10c without passing through the gauze or the like, the cleaning efficiency is dramatically improved, and a constant cleaning effect can be obtained regardless of the skill of the operator. Also, the cleaning accuracy is improved.
[0038]
If each cleaning tool is held in a circular shape in the insertion hole 6 when the ultrasonic vibration is applied to the cutting tools 10a, 10b, and 10c, it is difficult to clean one cutting tool behind another cutting tool. Such a situation can be prevented, and each cutting tool can be uniformly cleaned.
[0039]
By the way, in order to dry the cutting tools 10a, 10b, 10c cleaned by the stand 1, here, the operator does not wipe each of the water with a cloth or the like, but uses a cleaning liquid shown in FIGS. Use a removal device. The dental cutting tool cleaning device 60 is configured such that the stand 1 is detachably attached to the cleaning liquid removing device 30.
[0040]
The cleaning liquid removing apparatus 30 includes an apparatus main body 31 having the same configuration as a rotary drive mechanism of a general centrifugal separator, and a dehydration chamber 32 provided on an upper part of the apparatus main body 31. A thrust bearing 33 is provided inside the apparatus main body 31, and a rotary shaft 34 is supported by the bearing 33. A motor 35 is provided inside the apparatus main body 31, and the power of the motor 35 is transmitted to the rotating shaft 34 via gears 36 and 37, so that the rotating shaft 34 rotates. Power is supplied to the motor 35 through an AC adapter 38 and an AC-DC converter (or thyristor) 39, and the rotation speed of the motor 35 can be adjusted by a rotation controller 40.
[0041]
The rotating shaft 34 has a D-cut cross-sectional shape so as to penetrate the bottom surface 44 of the dehydrating chamber 32 and be able to be fitted into the shaft 4 of the stand 1. A screw surface is formed at least on the outer periphery of the upper end of the rotating shaft 34, and a cap 43 can be screwed onto the screw surface. Further, a spacer 45 that rotates integrally with the rotating shaft 34 is provided near the bottom surface 44 of the rotating shaft 34 inside the dehydrating chamber 32.
[0042]
The side wall 41 of the dewatering chamber 32 is made of a transparent resin, and the side wall 41 is provided with a drain port 46 communicating with the outside of the dewatering chamber 32. The drain 46 is connected to a vacuum unit 48 of the dental unit by a tube 47 made of silicone rubber (or rubber having the same physical and chemically stable elastic properties). A lid 50 that covers the opening 51 of the dehydration chamber 32 is detachably attached to the upper part of the side wall 41. The lid 50 is attached to the outside when the vacuum inside the dehydration chamber 32 becomes negative pressure by the vacuum device 48. A vent hole 49 for taking in the air is formed.
[0043]
To dry the cutting tools 10a, 10b, and 10c using the cleaning liquid removing device 30, the operator takes out the stand 1 from the container 20 after the completion of the ultrasonic cleaning, and installs the stand 1 in the dewatering chamber 32. I do. Specifically, in the dehydration chamber 32, the rotating shaft 34 protruding from the bottom surface 44 is fitted into the shaft 4 of the stand 1, and the cap 43 is screwed onto the threaded surface of the rotating shaft 34 protruding from the upper end of the shaft 4. 51 is closed with a lid 50.
[0044]
Here, since the cross-section of the shaft 4 and the rotary shaft 34 is D-shaped, the rotational force of the rotary shaft 34 is reliably transmitted to the shaft 4, and a slip occurs between the rotary shaft 34 and the shaft 4. It is possible to prevent the two from being shaken or the rotating shaft 34 from running idle. In addition, since the stand 1 is fixed from above by the cap 43, the stand 1 is also prevented from rising upward during rotation. Further, since a gap is secured between the leg 8 of the stand 1 and the bottom surface 44 of the dehydration chamber 32 by the spacer 45, the situation where the leg 8 slides on the bottom surface 44 when the stand 1 rotates is also prevented.
[0045]
When the stand 1 is mounted on the rotating shaft 34, the operator turns on a power switch (not shown) provided on the apparatus main body 31. Then, the motor 35 is driven to start the rotation of the rotating shaft 34, and this rotating force is also transmitted to the shaft 4, and the stand 1 rotates at high speed. Due to the centrifugal force caused by this high-speed rotation, the cleaning liquid attached to the surfaces of the cutting tools 10a, 10b, 10c and the stand 1 separates from those surfaces and scatters inside the dehydration chamber 32. By driving the vacuum device 48 and sucking it from the drain port 46, it can be removed from the inside of the dewatering chamber 32.
[0046]
When the stand 1 is driven to rotate for a certain period of time, the cleaning liquid adhering to the cutting tools 10a, 10b, 10c and the surface of the stand 1 is almost completely blown off, and the operator wipes off the cleaning liquid adhering to them. These can be transferred to the next process such as sterilization without any treatment.
[0047]
In the cleaning liquid removing apparatus 30 according to the present embodiment, the apparatus main body 31 rotates the stand 1 to scatter and remove the cleaning liquid held on the stand 1 and adhered to the cutting tools 10a, 10b, 10c. Therefore, even if the cutting tools 10a, 10b, and 10c have complicated shapes, the attached cleaning liquid can be easily removed without carefully wiping them one by one, and the drying of the cleaning tools can be started. Work and time can be greatly reduced. Further, since the occurrence of unwiped residue can be suppressed regardless of the skill of the operator, the cleaning accuracy can be improved.
[0048]
Furthermore, in the present embodiment, since the water in the dehydrating chamber 32 is sucked by the vacuum device 48, the droplets scattered from the cutting tools 10a, 10b, 10c and the stand 1 are effectively prevented from adhering to them again. In addition, the generation of rust can be reliably prevented, and the maintenance of each cutting tool and the stand 1 after the use of the cleaning liquid removing device 30 is also facilitated. Since the vacuum device 48 also serves as a dental unit, there is no need to separately provide a new suction device, which is economical.
[0049]
Note that the present invention is not limited to the above-described embodiment. For example, in the above-described embodiment, the stand 1 is used for a cutting tool for implant treatment, but the cutting of diamond bars, carbide bars, steel bars, and the like is performed. It may be used as a stand for a tool. Further, the cutting tool is not limited to medical and dental cutting tools, and may be, for example, an industrial cutting tool.
[0050]
Further, in the stand 1, the holding plates 2a, 2b, 2c and the retaining plate 3 are disc-shaped, but the shape of each plate is not limited to this, and may be, for example, rectangular or regular polygonal. It doesn't matter. However, in consideration of inertia during rotation, space efficiency, and the like, the shape of each plate is preferably a disk shape.
[0051]
The materials of the holding plates 2a, 2b, 2c and the retaining plate 3 are not limited to resin, and may be made of, for example, metal. However, by making each plate of hard resin as described above, The cutting tools held by them can be prevented from being damaged. When each plate is made of metal, a cylindrical adapter made of Teflon (registered trademark) resin that covers the peripheral surface of the through hole 6 is attached to the through hole 6 of each holding plate, so that the cutting tool is effectively scratched. Can be prevented.
[0052]
Further, the number of the holding plates may be appropriately selected as needed, and the arrangement of the through holes 6 may be appropriately changed according to the cutting tool to be cleaned. Some of the cutting tools 6b may be closed from below by a resin plate adhered to the lower surface of the holding plate 2b, and the lower end of the short cutting tool may be received by the resin plate.
[0053]
