  The following embodiments will be described in detail with reference to the drawings. In the drawings, the same or corresponding portions have the same reference characters allotted, and description thereof will not be repeated. In the present embodiment, a handpiece used for dentistry will be described as an example of a medical / dental handpiece. Note that the handpiece is not limited to dentistry, and can be applied to all medical treatments such as oral surgery, otolaryngology, surgery, and veterinary medicine.

(A. Overview)
The dental handpiece 4 (hereinafter, simply referred to as “handpiece 4”) is attached to the dental care device 10 (hereinafter, simply referred to as “medical device 10”). The surgeon can perform dental care by attaching the handpiece 4 to the medical treatment device 10.

  The handpiece 4 may be contaminated with bacteria, viruses, etc. by contacting the patient during use. For this reason, in maintenance of the handpiece 4 after use, it is necessary to perform a treatment such as sterilization on the handpiece 4 before using it for the next patient. In addition, since the durability load is applied to the handpiece 4 by the sterilization process, the number of times the handpiece 4 is used may be determined in advance.

  Therefore, it is necessary to individually identify and manage the handpieces 4. FIG. 1 is a diagram schematically showing an application scene of the handpiece 4. The handpiece 4 is managed by the management system 1000 shown in FIG. The management system 1000 includes a handpiece 4, a medical device 10, a computer 100, and a server 200.

  The handpiece 4 can be attached to the medical device 10 and detached from the medical device 10. The handpiece 4 is provided with a two-dimensional identification code 43 indicating the identification number of the handpiece 4. The identification code 43 only needs to be optically readable. For example, the identification code 43 may be an identification code such as a one-dimensional barcode, or a visible character (for example, a number). The identification number is identification information for individually identifying the handpiece 4, such as a unique serial number assigned to the handpiece 4 to which the identification code 43 is attached. Various codes such as General Specification 1 (GS1) data matrix (two-dimensional symbol) and QR code (registered trademark) can be adopted as the two-dimensional identification code. In addition, as an identification code such as a one-dimensional barcode, General Specification 1-128 (GS1-128), GS1 Japan, Global Trade Item Number (GTIN), and Japan Article Number (JAN), which are international standard barcodes, are used. , European Article Number (EAN), Universal Product Code (UPC) and the like.

  The medical care device 10 is communicably connected to the computer 100. Further, the computer 100 is communicably connected to the server 200. The server 200 stores management information 22 indicating the usage status of each handpiece 4. The management information 22 is stored for each handpiece 4.

  The medical treatment device 10 includes a medical treatment chair 1, an illuminating device (operating light) 7, a control device 9, and a reader 10a capable of reading an identification code 43 attached to the handpiece 4.

  The reader 10a is a known optical code reader that can optically read the identification code 43. The reader 10a includes an imaging unit and an acquisition unit that acquires an identification number from an image of the identification code 43 captured by the imaging unit. The imaging unit is configured by, for example, a light receiving sensor in which solid-state imaging elements (light receiving elements) such as a CCD element and a CMOS element are two-dimensionally arranged. The reading unit is realized by, for example, a processor such as a CPU (Central Processing Unit) executing a program stored in a program memory. The reading unit analyzes the light receiving signal output from the light receiving sensor using an image recognition technique or the like, analyzes the information encoded in the identification code 43, and acquires the identification information.

  In the example shown in FIG. 1, the reader 10a is provided on the upper part of the medical chair 1, specifically, is provided on the medical chair 1, and is attached to the illumination device 7 which illuminates the medical treatment site from above. Although the reader 10a may be provided at any position of the medical treatment device 10, it is preferable that the reader 10a be provided within a reach of the operator during medical treatment.

  The control device 9 controls various devices provided in the medical treatment device 10 and manages various information acquired by the medical treatment device 10. The control device 9 sends the identification information read by the reader 10a to the computer 100. The computer 100 searches the management information 22 of the handpiece 4 corresponding to the identification number read by the reader 10a from the server 200, and acquires the corresponding management information 22. The computer 100 acquires the usage status of the handpiece 4 from the management information 22 and executes a process according to the usage status.

  The usage status includes, for example, the total number of times the handpiece 4 has been used, the total usage time of the handpiece 4, information indicating whether the handpiece 4 has been sterilized, and oil in the handpiece 4 that needs refueling. Including the remaining amount. The “processing according to the use situation” includes, for example, processing such as a repair request or replacement for stopping use when the handpiece 4 is not suitable for use. Unsuitable for use means, for example, that the total number of uses or the total use time has exceeded or is about to reach a predetermined limit, that the oil has not been sterilized, that the oil has not been used, For example, when the remaining amount is equal to or less than a predetermined value. The “process for stopping use” is a concept that includes a process of disabling the handpiece 4 and a process of notifying that the handpiece 4 is not suitable for use.

  Note that the computer 100 acquires the usage status of the handpiece 4 from the management information 22 and executes a process according to the usage status. However, the control device 9 and the computer 100 execute these processes in cooperation. You may make it.

  Further, the computer 100 executes a process of updating the management information 22 of the handpiece 4 corresponding to the identification number read by the reader 10a. For example, the computer 100 updates the number of times of use and the time of use, or changes information indicating that sterilization has been performed to information indicating that sterilization has not been performed.

  As described above, when the handpieces 4 are individually managed based on the identification code 43, a process of reading the identification code 43 is necessarily required. Hereinafter, various embodiments of the handpiece 4 provided with the identification code 43 will be described.

(Embodiment 1)
FIG. 2 is a perspective view of the handpiece 4a according to the first embodiment. The handpiece 4a is a contra-angle handpiece such as an air turbine handpiece. The handpiece 4a includes a main body 41, and a grip 42 provided on the main body 41 and held by an operator. Further, at the position of the main body 41 that does not become the grip 42, an identification number is assigned an identification code. 43 is attached. The grip section 42 is an area that the operator grips when performing medical treatment. For example, in FIG. 2, the identification code 43 is provided at the rear of the handpiece.

  The identification number is identification information for individually identifying the handpiece 4, such as a unique serial number assigned to the handpiece 4a to which the identification code 43 is attached. The identification code 43 may be a two-dimensional identification code such as a GS1 data matrix, or may be an identification code such as a one-dimensional GS1-128 barcode. Further, the identification code 43 may be character information such as a number, or may be a combination of a barcode and a number. In the following embodiment, a description will be given assuming that a two-dimensional identification code is attached to the handpiece 4a.

  By directly writing the identification code on the handpiece, it is possible to visually recognize that the identification information is written on the handpiece, as compared with the case where electronic identification information is provided by RFID or the like. You can immediately determine whether or not. In addition, since the deterioration and dirt of the printing portion of the identification information can be determined by looking at it, errors are unlikely to occur. Further, the cost can be reduced as compared with the provision of the electronic identification information.

  Since the identification code 43 is attached to the position of the main body portion 41 that does not become the grip portion 42, the identification code 43 is prevented from being covered by the operator's hand when the operator grips the handpiece 4a. can do. As a result, the identification code 43 can be read by the reader 10a even while the operator holds the handpiece 4a. Therefore, the surgeon does not need to change the way of holding the handpiece 4a while being conscious of having the reader 10a read the identification code 43.

  In other words, the identification code 43 is attached to a position where the reader 10a, which is an example of a reading device provided in the medical treatment device 10, can read the identification code 43 when the operator is holding the handpiece 4a. ing.

  Further, when the identification code 43 is touched by a hand, the identification code 43 may be worn and the identification code 43 may be removed from the handpiece 43a. The identification code 43 is information for identifying an individual handpiece, and is important information for causing the management system 1000 to function. Since the identification code 43 is attached to the position of the main body portion 41 that does not become the grip portion 42, it is possible to prevent the identification code 43 from being worn out and removed from the handpiece 43a, so that important information cannot be read. .

  Further, the handpiece 4a has a flat portion 47 in which a part of the outer peripheral surface is a smooth surface, and the identification code 43 is attached to the flat portion 47. By attaching the identification code 43 to the flat portion 47, the identification code 43 can be more easily read than when the identification code 43 is attached to a curved surface. Printing is easier when the identification code 43 is attached to a flat surface than when the identification code 43 is attached to a curved surface.

  The method of attaching the identification code 43 to the handpiece 4a is not limited to the method of directly attaching the identification code 43 to the handpiece 4a, but may be the method of indirectly attaching the identification code 43 to the handpiece 4a, for example. Good. Examples of a method of directly attaching the handpiece 4a include a method of attaching ink and a method of attaching the handpiece 4a by changing the surface shape such as a laser marker or an engraving. The method of attaching the identification code 43 by changing the shape of the surface such as a laser marker or an engraving is preferable in that it is harder to erase than the method of attaching with an ink.

  When the identification code 43 is directly printed, a transparent heat-resistant coating may be applied to the printing location. Due to the nature used in the oral cavity, the handpiece 4 needs to be autoclaved as a sterilization treatment every time it is used. Therefore, the identification code 43 attached to the handpiece 4 also needs to secure sufficient resistance to processes such as cleaning and sterilization. By applying the transparent heat-resistant coating to the printed portion, the resistance of the identification code 43 to the washing process or the sterilization process of the autoclave or the like can be improved.

  The method of applying a transparent heat-resistant coating includes a method of applying a heat-resistant transparent paint, a method of attaching a transparent heat-resistant sheet, and the like. Further, as the transparent heat-resistant material, for example, a polyester resin, an acrylic resin, or the like can be used.

  FIG. 3 is a side view of the handpiece 4a according to the first embodiment. The main body section 41 includes a head section 44 for a medical treatment site, a grip section 42, and a tubular section 45. Here, medical treatment is a concept including medical examination and treatment.

  The head section 44 is provided at the tip of the main body section 41 and is a part to be inserted into the oral cavity. Assuming that one end of the main body 41 provided with the head portion 44 is a tip, the cylindrical portion 45 is provided at the other end of the main body 41. In the following, the direction in which the head portion 44 is provided is referred to as “front”, and the direction in which the tubular portion 45 is provided is referred to as “rear”. When the handpiece 4a is viewed from behind the handpiece 4a, the right side is referred to as "right" and the left side is referred to as "left". That is, the side view shown in FIG. 3 is a left side view.

  The head section 44 includes a connection portion 44b to which a tool 44c can be attached and detached, a medical treatment surface 44a provided with the connection portion 44b, and a cap 44d provided at a position facing the medical treatment surface 44a. The operator operates the handpiece 4a such that the medical treatment surface 44a and the medical treatment site X face each other, and performs a treatment on the medical treatment site X using the tool 44c. Hereinafter, the medical treatment surface 44a side of the handpiece 4a is referred to as "lower", and the cap 44d side is referred to as "upper". Note that the cap 44d forms an upper surface 44e of the head unit 44.

  The grip part 42 is located between the head part 44 and the cylindrical part 45. That is, the head portion 44 is connected to the front side of the grip portion 42, while the tubular portion 45 is connected to the rear side of the grip portion 42. The tubular portion 45 has a connecting portion 46 at the rear end for connecting to the medical care device 10 that controls the driving of the handpiece 4a.

  A flat portion 47 is provided on the left side surface of the outer periphery of the cylindrical portion 45, and an identification code 43 is attached to the flat portion 47. That is, the identification code 43 is attached to the outer periphery of the tubular portion 45. That is, the identification code 43 is attached not to the front of the main body 41 inserted into the oral cavity but to the rear. During medical treatment, the front area of the main body 41 is inserted into the oral cavity. Therefore, the possibility that the outer periphery of the main body 41 is worn is lower in the rear area of the main body 41 than in the front area. Since the identification code 43 is attached to the outer periphery of the cylindrical portion 45 provided behind the main body 41, the identification code 43 can be prevented from being worn.

  FIG. 4 is an end view of the handpiece 4a according to the first embodiment. 4 (A) is an AA end view in FIG. 3, FIG. 4 (B) is a BB end view in FIG. 3, FIG. 4 (C) is a CC end view in FIG. 3, FIG. (D) is a DD end view in FIG. 3, and FIG. 4 (E) is an EE end view in FIG.

  As shown in FIG. 4, the diameter changes from the AA end to the BB end, and the portion from the AA end to the BB end has a truncated cone shape. On the other hand, the diameter does not change from the CC end to the EE end, and the portion from the CC end to the EE portion has a columnar shape.

  As shown in FIG. 3, a portion from the AA end to the BB end is included in the grip portion 42. On the other hand, the portion from the CC end to the EE portion is included in the tubular portion 45. That is, the cylindrical portion 45 has a cylindrical shape.

  Further, as shown in FIG. 4E, a flat portion 47 is formed on the outer peripheral surface of the tubular portion 45 of the main body portion 41. The identification code 43 is attached to the flat surface 47. The flat portion 47 has such a shape that the side surface of the cylindrical portion 45 is scraped off.

  In the handpiece 4a of the first embodiment, the flat portion 47 is formed on the cylindrical portion 45, and the identification code 43 is attached to the flat portion 47. However, the handpiece 4a has a curved surface without forming the flat portion 47. May be given an identification code 43. Specifically, the identification code 43 may be attached to the curved surface of the cylindrical tubular portion 45 whose diameter does not change from the CC end portion to the EE portion. A curved surface whose diameter does not change is a surface whose curvature does not change along the longitudinal direction. As compared with the case where the identification code 43 is attached to the curved surface of the truncated cone-shaped portion where the curvature changes along the longitudinal direction, the surface where the curvature does not change along the longitudinal direction is easier to attach the identification code 43.

(Embodiment 2)
FIG. 5 is an end view of the handpiece 4b according to the second embodiment. The handpiece 4b according to the second embodiment differs from the handpiece 4a in that a concave portion 48 is formed in the flat portion 47 on a part of the outer peripheral surface of the cylindrical portion 45 and the identification code 43 is attached to the concave portion 48. different. Specifically, the overall shape of the handpiece 4b according to the second embodiment is different from the handpiece 4a only in that a concave portion 48 is formed in the flat portion 47, and the other shapes are the handpiece 4b. 4a.

  The concave portion 48 shown in FIG. 5 is formed on the outer peripheral surface of the cylindrical portion 45 and has a shape buried in the center direction of the cylindrical portion 45. Further, the concave portion 48 has a predetermined depth, and the bottom thereof is a flat surface (the bottom surface 48a).

  It is preferable that the depth of the recess 48 is such that a part of the identification code 43 is not hidden by the shadow generated by the side surface 48b of the recess 48 when the identification code 43 is read. Specifically, it is preferable that the depth of the concave portion 48 is shorter than the distance from the bottom surface to the end of the identification code 43.

  By attaching the identification code 43 to the recess 48, the frequency with which the identification code 43 rubs against surrounding objects can be reduced. As a result, wear of the identification code 43 can be prevented. Since the bottom surface 48a of the concave portion 48 is a flat surface, the effect that the identification code 43 is easily printed and the effect that the identification code 43 is easy to read are obtained as in the handpiece 4a according to the first embodiment. However, the bottom surface 48a is not limited to a flat surface and may be a curved surface.

  Further, in the second embodiment, the description has been given assuming that the concave portion 48 is provided on the plane, but the concave portion may be provided on the curved surface.

  Further, the identification code 43 may be protected by attaching a transparent window to the upper part of the concave portion 48. By doing so, the wear of the identification code 43 can be further prevented. Further, a transparent window may be provided above the concave portion 48 so as to eliminate irregularities on the outer peripheral surface of the main body 41. By doing so, the unevenness of the outer peripheral surface is eliminated, and the outer peripheral surface of the handpiece can be smoothed. The method of removing the irregularities on the outer peripheral surface is not limited to the method of attaching the window, but may be, for example, a method of fitting a convex body corresponding to the concave portion 48 into the concave portion 48. Further, the above-mentioned transparent heat-resistant coating may be applied to the concave portion 48 so that the outer periphery may have a cylindrical shape along the outer diameter of the handpiece.

(Embodiment 3)
FIG. 6 is a view showing a handpiece 4c according to the third embodiment. The handpiece 4c differs from the handpiece 4a in the position where the identification code 43 is attached.

  The handpiece 4c has a head portion 44 at the distal end, similarly to the handpiece 4a. Further, similarly to the handpiece 4a, the head section 44 is provided at a position facing the medical treatment surface 44a, a connecting portion 44b provided on the medical treatment surface 44a, a tool 44c attached to the connecting portion 44b, and the medical treatment surface 44a. And a cap 44d. The cap 44d forms an upper surface 44e of the head unit 44.

  When the medical treatment surface 44a side is downward and the cap 44d side is upward, the handpiece 4c has a flat portion 47 on the upper surface of the tubular portion 45, and the identification code 43 is attached to the flat portion 47. Also in the handpiece 4c according to the third embodiment, the identification code 43 is attached to the flat portion 47, and the identification code 43 is attached to the rear area of the handpiece 4c. The same effect as that of the handpiece 4a can be obtained.

  In the third embodiment, in particular, since the identification code 43 is attached to the upper surface of the tubular portion 45, the identification code 43 is hidden behind the operator when the operator grips the grip portion 42. The identification code 43 can be easily read. In addition, by attaching the identification code 43 to the upper surface of the cylindrical portion 45, the identification code 43 is attached even if the operator holds the handpiece 4c with either of the right hand and the left hand. The surface is not on the side where the operator's body is located. Therefore, regardless of the surgeon's dominant arm, the identification code 43 can be set at a position where it can be easily read.

  Note that the identification code 43 may be attached to the surface on the medical treatment surface 44a side, that is, the bottom surface of the tubular portion 45, but the identification code 43 is provided at any position from the side surface to the upper surface. The identification code 43 is less likely to be hidden behind the surgeon himself, and the identification code 43 is easy to read.

(Embodiment 4)
FIG. 7 is a perspective view of a handpiece 4d according to the fourth embodiment. The handpiece 4d differs from the handpiece 4a in that a plurality of identification codes 43 are provided. That is, the handpiece 4d is provided with the identification code 43a in addition to the identification code 43.

  In the handpiece 4d, an identification code 43a is attached to a plane portion 47a formed on the upper surface of the tubular portion 45. Both the identification code 43 and the identification code 43a are two-dimensional identification codes. Information indicated by the identification code 43 and the identification code 43a is common to each other. As described above, since the information indicated by the identification code 43 and the information indicated by the identification code 43a are common to each other, one of the identification code 43 and the identification code 43a can be read, and the range in which the identification information can be read is limited. spread.

  Although the identification code 43 and the identification code 43a are both two-dimensional identification codes, one may be a one-dimensional identification code and the other may be a two-dimensional identification code. By attaching different types of identification codes, the number of readers that can be used increases.

  Further, the information indicated by the identification code 43 and the information indicated by the identification code 43a may be different from each other. By doing so, information that can be read from the handpiece 4d can be increased.

  Specifically, the information indicated by the identification code 43 is used as the identification information, the information indicated by the identification code 43a is used as the information on how to use the handpiece 4d, and the identification code 43a is read by the reader 10a. It may be configured to display information on the usage on a display unit such as a monitor. In this way, it is possible to show the operator how to use the handpiece even if the instruction manual is not at hand.

  Further, one of the identification code 43 and the identification code 43a may be an identification code attached with a rewritable paint, and the other may be an identification code attached with a non-rewritable paint.

  In the fourth embodiment, an example is shown in which two identification codes are attached to the handpiece, but three or more identification codes may be attached. In addition, when two identification codes are attached, the attaching position is not limited to the example illustrated in FIG. 7, and the identification code may be attached to each of the right side surface and the left side surface. By doing so, both the left-handed operator and the right-handed operator can use the handpiece in the same manner.

(Embodiment 5)
FIG. 8 is a perspective view of a handpiece 4e according to the fifth embodiment. The handpiece 4e differs from the handpiece 4a in that an identification code 43 is attached to the head 44.

  The handpiece 4e is a contra-angle handpiece. The head portion 44 includes a medical treatment surface 44a facing the medical treatment site X, a connection portion 44b to which a tool 44c provided on the medical treatment surface 44a can be attached, and a cap 44d provided at a position facing the medical treatment surface 44a. . The cap 44d forms an upper surface 44e of the head unit 44. The identification code 43 is provided on an upper surface 44e of the head unit 44. In the contra-angle handpiece, the upper surface 44e is flat. Therefore, the same effect as in the case of attaching the identification code 43 to the formed flat portion 47 can be obtained.

  That is, in the first to fourth embodiments, the flat portion is formed on the outer peripheral surface of the main body portion 41 and the identification code 43 is attached to the formed flat surface. In a piece, it is not necessary to form a plane. For example, in a handpiece provided with a quadrangular prism-shaped part having a square cross section orthogonal to the longitudinal axis, an identification code may be attached to a plane part of the part.

  The cap 44d is a component that can be removed when performing maintenance on the handpiece 4e. Therefore, from the viewpoint that the cap 44d may be lost, it is preferable to attach the identification code 43 to a component that cannot be removed from the handpiece 4e, rather than attaching the cap 44d.

(Embodiment 6)
FIG. 9 is a side view of a handpiece 4f according to the sixth embodiment. The handpiece 4f according to the sixth embodiment can read and write information by short-range (several cm to several m depending on the frequency band) wireless communication using an electromagnetic field, a radio wave, or the like in addition to the identification code 43. It differs from the handpiece 4a in that a possible RFID (Radio Frequency IDentification) tag 50 is attached. The handpiece 4f differs from the handpiece 4a in that an identification code 43 is attached to a curved surface, but the position where the identification code 43 is attached is approximately the same as the handpiece 4a.

  The handpiece 4f has an RFID tag 50 readable by an electromagnetic field or a radio wave in addition to the optically readable identification code 43. A reader using such a method can be used. As a result, the versatility of the handpiece 4f can be improved. Further, the identification code 43 can prevent the identification number from being erased by mistake because the information cannot be rewritten. However, the information cannot be rewritten. Since the handpiece 4f includes the RFID tag 50 capable of rewriting information, the range of information to which the handpiece 4f can be attached can be expanded, and versatility is increased.

  The structure of the RFID tag 50 will be described with reference to FIG. FIG. 10 is a schematic diagram for explaining a configuration of an RFID tag 50 attachable to the handpiece 4f according to the sixth embodiment. FIG. 10A is a perspective view illustrating an appearance of the RFID tag 50, and FIG. 10B is a perspective view illustrating an internal structure of the RFID tag 50.

  The RFID tag 50 is a rubber band type IC tag. The RFID tag 50 includes a band portion 50a, a protection member 50b, and an RFIC (Radio Frequency Integrated Circuits) chip 55. The band portion 50a is elastic and has a ring shape that can be attached to the handpiece 4f. For the band portion 50a, for example, a fluororubber having autoclave resistance is used. The band portion 50a may be made of a synthetic rubber, such as silicon rubber, in addition to the fluorine rubber. Here, the ring-shaped shape is a shape when attached to the handpiece, and is not limited to the shape before the attachment. Therefore, the band portion 50a has a belt-like shape before the attachment, and is attached to the handpiece. In this case, a part of the belt shape may be connected with a metal fitting or a binding portion to form a ring shape. For example, an RFID tag whose band portion is made of a binding band may be used.

  The RFIC chip 55 is provided in a part of the band unit 50a, and can store an identification number that is identification information of a handpiece. The RFIC chip 55 can read and write information through short-range (several cm to several meters depending on a frequency band) wireless communication using an electromagnetic field, a radio wave, or the like. The RFIC chip 55 shown in FIG. 10B is a passive RFIC chip connected to an antenna (not shown). Therefore, the RFIC chip operates using radio waves from the reader (reader) as an energy source, and there is no need to incorporate a battery in the RFID tag 50. Note that the RFIC chip 55 is not limited to a passive type RFIC chip, and may be an active type RFIC chip connected to a battery built in the RFID tag 50.

  The protection member 50b seals the RFIC chip 55 on the band portion 50a by a rubber molding technique. The protection member 50b has heat resistance, and seals the RFIC chip 55 to improve processing such as cleaning and sterilization, for example, the resistance of an autoclave. Further, the protection member 50b has a substantially circular shape in plan view, and a portion covering the RFIC chip 55 has a convex curved shape. This makes it easier to receive radio waves from the reader / writer with an antenna (not shown), and there is no portion that gets caught by the RFID tag 50, so that it does not hinder the operator even when attached to a medical handpiece.

  Two types of frequency bands that can be used for the RFID tag 50 in Japan are available: the HF band (13.56 MHz) and the UHF band (915 MHz to 930 MHz). The HF band is widely used in non-contact IC cards and the like, and the RFID tag 50 can be read at a very short distance. On the other hand, in the UHF band, it is possible to expect the re-entry of radio waves as compared with the HF band, and the RFID tag 50 can be read at a distance farther than the HF band. Note that the frequency band that can be used for the RFID tag 50 is not limited to the above-described frequency band, and may be changed depending on countries and regulations.

  FIG. 11 is a perspective view of a state where the RFID tag 50 is not attached to the handpiece 4f according to the sixth embodiment. The handpiece 4f is provided with an outer peripheral groove 49 that is in contact with the band 50a of the RFID tag 50 on the outer periphery of the tubular portion 45 behind the handpiece 4f that does not become the gripping portion 42.

  The outer peripheral groove 49 makes a round around the tubular portion 45 so that the band portion 50a of the RFID tag 50 is accommodated. However, the outer circumferential groove 33 only needs to be able to shift or position the RFID tag 50, and is not limited to the shape surrounding the cylindrical portion 45, and may be any shape as long as a part of the band portion 50a abuts. Further, the outer peripheral groove 49 is provided behind the grip portion 42, but may be provided on the head portion 44 side of the handpiece 4 f at a position other than the grip portion 32.

  By providing the outer peripheral groove 49, the RFID tag 50 can be attached to the handpiece 4f such that the band portion 50a fits in the outer peripheral groove 49. As a result, the position of the RFID tag 50 does not shift while the operator is using the handpiece 4f. Further, regardless of the person who attaches the RFID tag 50, the RFID tag 50 can be attached to the same position where the band portion 50a fits in the outer peripheral groove 49.
