The present invention relates to a wireless transmission unit for a dental instrument with a built-in camera, and a dental instrument with a built-in camera.
In the field of dental treatment, there has recently been developed a dental instrument with a built-in camera, which also has an image picking-up function for intraoral observations in addition to a medical treatment or procedure function upon performing treatment or a procedure of an affected part (target location) in an oral cavity.
There has been proposed in, for example, Patent Document 1, a dental image pick-up apparatus configured in such a manner that a camera is attached to a dental instrument such as an ultrasonic scaler and connected to a controller for image processing by a cable, and camera image information of a target location image-processed by the controller is transmitted to an image display means by wireless to display an image of the target location in an oral cavity (Patent Document 1: FIG. 21, etc.).
In the case of this dental image pick-up apparatus, however, it is configured such that the camera image is transmitted to the image display means by wireless after the camera image is transmitted to the controller once by the cable. It is a current status that inclusive of this Patent Document 1, there are not yet such a wireless transmission unit that is detachably mounted to a dental instrument itself and transmits camera images to various destination apparatuses by wireless without interposing a controller to enable provision for an image display, and further such a dental instrument that is equipped with such a wireless transmission unit integrally and transmits camera images to various destination apparatuses by wireless to enable provision for an image display.

The present embodiment 1 is intended to be applied to an air turbine-driven camera built-in hand piece 1 as one of dental instrument with a built-in camera.
The camera built-in hand piece 1 of the present embodiment 1 has, as illustrated in
An air pipe 72 which constitutes an air flow path system for guiding compressed air supplied from the unillustrated dental care unit, and a water pipe 73 which constitutes a water flow path system for guiding pressurized water and a power cable 74 for supplying a required voltage are installed inside the connecting hose 71.
Then, there are provided within the dental hose section 12, the coupling portion 11, and the grip part 3 including the head part 14, although omitted in detailed structure, an air flow path system for guiding an air flow for an air turbine force-fed to the head part 14 of the hand peace main section 2 via the dental hose section 12 and guiding compressed air for an air flow injected toward the cutting tool 16 from the head part 14, and a water flow path system for guiding pressurized water for a water flow injected toward the cutting tool 16 from the head part 14, which is force-fed to the head part 14 of the hand peace main section 2 via the dental hose section 12.
Further, a light source part 21 comprised of, for example, an LED (Light Emitting Diode) element (one having a drive voltage DC 3.3V, for example) for illumination is arranged at the tip portion of the coupling portion 11, which occupies the inside of the grip part 3. Furthermore, a rod fiber 22 is placed in such an arrangement that one end thereof is exposed at a position near the head part 14 in the grip part 3 and the other end thereof is faced to the vicinity of the light source part 21. Light emitted from the light source part 21 is configured to be guided via the rod fiber 22 and emitted from one end thereof to a region of a target location (affected part P) by the cutting tool 16 as illumination light.
The light source part 21 is lit and driven by a driving voltage supplied from the power cable 74 although its wiring system is not shown in the drawing.
Further, a camera unit 31 which configures a camera for picking up the target location is built in at the position closer to the emission end of the rod fiber 22, of the head part 14 in the grip part 3.
Here, the camera unit 31 will be described in detail with reference to
The camera unit 31 has, for example, a cylindrical support tube 32 which is 1.2 mm in diameter, about 1.1 mm in inner diameter, and 3 mm in length, a condenser lens unit 33 having a diameter of Φ1=1.1 mm, which is placed to face a light entrance end thereof to one end face of this support tube 32, an image pick-up unit 34 disposed opposite to the condenser lens unit 33 with a predetermined interval spaced therebetween within the support tube 32, and a cover member 35 fitted to the range from the other end face side of the support tube 32 to within the support tube 32.
The image pick-up unit 34 is equipped with a disk-shaped support substrate 37 having a diameter of 1.1 mm securely fixed in a state in which the center thereof is aligned with the optical axis of the condenser lens unit 33 within the support tube 32, and a color image sensor (CMOS: Complementary Metal Oxide Semiconductor) 38 mounted in a state in which color pixels are arranged on the surface of a sensor substrate 38a having outer dimensions of 0.84×0.74 mm and a thickness of 0.1 mm so that the number of the pixels assumes 320×240 pixels, and the center thereof coincides with the optical axis of the condenser lens unit 33.
The condenser lens unit 33 adopts, for example, one having optical characteristics of a viewing angle of 70 degrees and a focus range 3-50 mm.
Further, the camera unit 31 is configured to connect a signal cable 36 for transmitting an image signal of a picked-up target location and a drive cable 39 for supplying a voltage for the operation of a color image sensor 38 to the color image sensor 38, internally install these in a camera cable 40 as a connection wiring part, and allow the camera cable 40 to penetrate the cover member 35 so as to lead out to the rear side.
Next, the wireless transmission unit 51 according to the present embodiment 1 will be described in detail with reference to
As illustrated in
The penetration portion of the grip part 3 in the connection wiring part can be brought to resistant autoclave specifications by being taken as the waterproof specifications.
A connection system of the wireless transmission unit 51 and the camera unit 31 is schematically illustrated in
Next, the configuration contents of the image processing wireless transmission means 58 will be described with reference to
The image processing wireless transmission means 58 has a controller 59 which performs control of the image processing wireless transmission means 58, a power supply circuit unit 60 which fetches a required voltage supplied via the power supply connector part 57 and performs the supply of power necessary for each part of the image processing wireless transmission means 58, a camera drive power supply circuit unit 61 for driving the camera unit 31, an analog image signal receiving unit 62 which receives an image signal of a target location picked up by the camera unit 31, a color image generating unit 63 which generates target-location color image information, based on the image signal, a gain adjustment button 64 which adjusts the gain at the time of image generation processing, an auto white balance adjustment button 65 which adjusts the white balance at the time of the image generation processing, and a transmitting transmitter 66 which wirelessly transmits the purified target-location color image information to each destination apparatus.
As the wireless communication system of the transmitting transmitter 66, there may be mentioned examples of, e.g., an IEEE802.11-based wireless LAN system and a wireless communication system by infrared communication.
Next, the operation of the wireless transmission unit 51 according to the present embodiment 1, which is equipped with the camera built-in hand piece 1, will be described with reference to
In the camera built-in hand piece 1 of the present embodiment 1, when the cutting tool 16 mounted to the head part 14 is rotationally driven to perform treatment of an affected part P of a tooth corresponding to a target location of a certain patient, a drive voltage is supplied from the camera drive power supply circuit unit 61 of the image processing wireless transmission means 58 to the camera unit 31 through the linking connector part 56, the cylindrical connector section 53, and the connection wiring part, so that the image pick-up unit 34 is brought to an operating state to thereby pick up an image of the affected part P.
A signal of the image of the affected part P picked up by the image pick-up unit 34 is transmitted from the linking connector part 56 of the image processing wireless transmission means 58 to the analog image signal receiving unit 62 through the connection wiring part and the cylindrical connector section 53. The color image generating unit 63 generates target-location color image information on the basis of the image signal of the affected part P received by the analog image signal receiving unit 62.
The target-location color image information generated by the color image generating unit 63 is wirelessly transmitted from the transmitting transmitter 66 to such various destination apparatuses as illustrated in
As the destination apparatuses in this case, there may be mentioned, as shown in
Thus, for example, an affected part P and target-location color image information of its peripheral portion are displayed on the screen of the cart type image display means 85 as illustrated in
The image display means 83 of the dental care unit 81, a display unit 86a of the personal computer 86, and the image display means 88 of the head mounted display 89 are also similar to the case of the cart type image display means 85.
In the case of the above-described cart type image display means 85, if the cart 84 is placed closer to an operator actually carrying out the treatment of the affected part P, the operator is able to visually confirm the image display means 85 and clearly recognize the affected part P and the target-location color image information of its peripheral portion without using a mirror (Dental Mirror). It is therefore possible to reduce a dead angle area by the visual recognition of each part in an oral cavity, e.g., a root canal opening, a pulp horn, a pulpal floor, a cavity shadow, etc. and thereby achieve a stress reduction at the time of treatment.
Even in the case of the dental care unit 81, since the operator is able to visually confirm the image display means 83 and clearly recognize the affected part P and the target-location color image information of its peripheral portion without using the mirror, it is possible to reduce a dead angle area by the visual recognition of each part in the oral cavity, e.g., the root canal opening, pulp horn, pulpal floor, cavity shadow, etc. while enhancing operability in operation and achieve a reduction in stress at the time of treatment.
In the case of the personal computer 86, since the target-location color image information can be transmitted to any other number of personal computers (not shown) constructed with a LAN connection in advance in the dental clinic, it is also extremely simple and easy to realize information sharing about the target-location color image information in plural persons concerned such as a dentist, a dental technician, etc.
In the case of the head mounted display 89, since any person is able to mount the head mounted display 89 on the head thereof, the promotion of patient understanding to the treatment contents can also be achieved by causing the person to visually recognize target-location color image information through the image display means 88 in a state in which the head mounted display 89 is mounted on, for example, the head of the patient and the treatment is actually being performed.
An embodiment 2 of the present invention will be described with reference to
The present embodiment 2 is configured to mount a wireless transmission unit 51 to a camera built-in syringe (camera built-in multiway syringe) 91 being a dental instrument with a camera unit 31 built therein on the basis of a configuration similar to the above-described case.
A syringe body 92 which configures the camera built-in syringe 91 is equipped with a conduit of pressurized fluid (water or chemical solution), a conduit of compressed air, and a control valve for controlling those conduits respectively as is publicly known. The syringe body 92 is configured to selectively inject a plurality of types of dental working fluid from an injection nozzle 93 to the affected part P depending on the dental treatment and treat the affected part P.
Then, the camera unit 31, the connection wiring part, and further the power cable are incorporated into a position near a mounting portion of the injection nozzle 93 in the syringe body 92 on the basis of a configuration similar to the case of the embodiment 1 although omitted in detailed description to thereby configure a camera built-in syringe 91. Further, the wireless transmission unit 51 similar to the case of the embodiment 1 is configured to be mounted to the syringe body 92.
Even by the present embodiment 2, when the treatment of the affected part P is carried out by the camera built-in syringe 91, target-location color image information is wirelessly transmitted from a transmitting transmitter 66 of the wireless transmission unit 51 to such various destination apparatuses as illustrated in
An embodiment 3 of the present invention will be described with reference to
The present embodiment 3 is configured to mount a wireless transmission unit 51 to a camera built-in scaler 101 being a dental instrument having incorporated a camera unit 31 therein, based on a configuration similar to the above-described case.
A scaler body 102 which configures the camera built-in scaler 101 is, although omitted in detailed description, for example, one in which an ultrasonic vibrator with an ultrasonic vibration source (piezoelectric element) and a vibration transmitting member (horn) formed integrally is placed in the scaler body 102, a dental tip 103 which effectively acts on an affected part P is arranged in the tip of the scaler body 102, and the dental tip 103 is driven by ultrasonic vibrations to thereby perform scaling (tartar removal) of tooth surfaces, between the teeth, and below gingival edges, etc. in an oral cavity.
Then, the camera unit 31 and the connection wiring part are built in a position near an attachment portion of the dental tip 103 in the scaler body 102, based on a configuration similar to the case of the embodiment 1. Further, the wireless transmission unit 51 similar to the case of the embodiment 1 is configured to be mounted to the scaler body 102.
Even by the present embodiment 3, when the treatment of the affected part P is carried out by the camera built-in scaler 101, target-location color image information is wirelessly transmitted from a transmitting transmitter 66 of the wireless transmission unit 51 to such various destination apparatuses as illustrated in
Each of the configurations of the embodiments 1 through 3 described above is applicable even to various existing dental instruments in a simple manner.
Incidentally, it is also possible to make applications as a configuration in which the camera unit 31 is externally attached to a syringe body 92 in place of the camera built-in syringe 91 and the camera built-in scaler 101 and the wireless transmission unit 51 is mounted to the syringe body 92, and a configuration in which the camera unit 31 is externally attached to the scaler body 102 and the wireless transmission unit 51 is mounted to the scaler body 102.
That is, when an assumed reference line L extending in a projecting direction of the cutting tool 16 from the grip part 3 is assumed, the wireless transmission unit 51 is arranged to be inclined by a predetermined angle (e.g., 40 to 50 degrees) to the right with respect to the assumed reference line L as viewed from the tip side of the hand piece main section 2 in the case of right-handed specifications. Further, in the case of left-handed specifications, although not shown in the drawing, the wireless transmission unit 51 is arranged to be inclined by a predetermined angle (e.g., 40 to 50 degrees) to the left with respect to the assumed reference line L as viewed from the tip side of the hand piece main section 2.
The following effects are brought about by adopting such arrangements of the wireless transmission unit 51.
That is, when the treatment of the affected part P is performed using the camera built-in hand piece 1, the operator turns the hand piece main section 2 to take an appropriate angle using the index finger and thumb while supporting the hand piece main section 2 with the middle finger to thereby provide an optimal position for the affected part P.
In this case, as illustrated in
At this time, as illustrated schematically in
Further, by the above-described arrangement of the wireless transmission unit 51, it also becomes possible for the operator to clearly visually recognize the affected part P and the distal end of the cutting tool 16 without being blocked by the head part 14. Even from this point, good operability of the camera built-in hand piece 1 can be ensured.
The configuration related to the mounting arrangement of the wireless transmission unit 51 with respect to the hand piece main section 2 in such a camera built-in hand piece 1 as illustrated in
A dental instrument with a built-in camera according to an embodiment 4 of the present invention will be described with reference
The present embodiment 4 is one applied to an air turbine-driven camera built-in hand piece 1A as one of dental instruments with a built-in camera as with the case of the embodiment 1.
In the camera built-in hand piece 1A of the present embodiment 4, the same elements as in the case of the camera built-in hand piece 1 illustrated in
Although the camera built-in hand piece 1A of the present embodiment 4 is substantially similar to the case of the camera built-in hand piece 1 illustrated in
The camera built-in hand piece 1A equipped with the wireless transmission unit 51A of the present embodiment 4 can also exhibit various operations and effects similar to the case of the camera built-in hand piece 1 equipped with the wireless transmission unit 51 of the already-described embodiment 1 on the basis of the configuration in which the grip part 3 and the outer peripheral cylindrical body 111 are integrally formed.
Incidentally, it is also possible to adopt a configuration in which the outer peripheral cylindrical body 111 is integrally formed on the outer periphery of a dental horse section 12.
Also, as the arrangement of the outer peripheral cylindrical body 111 configuring the wireless transmission unit 51A in the camera built-in hand piece 1A equipped with the wireless transmission unit 51A of the present embodiment 4, the outer peripheral cylindrical body 111 can also be arranged to be inclined by a predetermined angle (e.g., 40 to 50 degrees) to the right with respect to an assumed reference line L as viewed from the tip side of the hand piece main section 2 in the case of right-handed specifications or arranged to be inclined by a predetermined angle (e.g., 40 to 50 degrees) to the left with respect to the assumed reference line L as viewed from the tip side of the hand piece main section 2 in the case of left-handed specifications as with the case illustrated in
Further, the structure of the outer peripheral cylindrical body 111 in the wireless transmission unit 51A of the present embodiment 4 is similarly applicable even to the camera built-in syringe 91 with the camera unit 31 of the embodiment 2 built therein, and the camera built-in scaler 101 of the embodiment 3 respectively. Even in these cases, operations and effects similar to the already-described case can be exhibited.
The present invention is widely applicable to various dental instruments such as an air turbine hand piece, a micromotor hand piece, a laser hand piece, a syringe or a scaler, etc., which respectively have incorporated a camera therein.
