Description

HANDPIECE STRUCTURE AND ILLUMINATED SYRINGE STRUCTURE BACKGROUND OF THE INVENTION This invention relates to an illuminated syringe tip and handpiece structure, and more particularly to an illuminated syringe tip and handpiece structure wherein a tip Disposable syringe is used to transmit light from a light source inside the adapter to the patient's oral cavity to provide illumination for the dentist. The patent of the U.S.A. No. 5,049,071 (Davis et al.) Discloses a disposable dental syringe tip made of plastic material. This patent also describes various adapters that can be used to connect the disposable syringe tip to the handpiece of a triple or three-way dental syringe structure. The description of this US patent. Do not. ,049,071 is incorporated herein by reference.

Additionally, the US patent. No. 5,192,206 ((Davis et al.) Contains additional description that relates to adapters for use in three-way dental syringe structures and the description of this patent of this US patent No. 5,192,206 is also incorporated herein by reference. Disposable plastic syringe tips have been quite broad in light of the serious concern regarding the increasing incidence of communicable diseases such as hepatitis and acquired immune deficiency syndrome (AIDS) .The dentists are taking extreme care to prevent the transmission of germs (Viral or bacteria) from one patient to the next.The plastic syringe tip already receives air and water under pressure under pressure.When operating the air button and water button on handpiece, the dentist can direct water, air or a combination of air / water spray to the patient's mouth for any dental procedures that are required. n supply light into the oral cavity to assist the dentist in performing necessary dental procedures. Most dental offices have an overhead lighting system with reflective surfaces that help to focus light from the patient's mouth. However, the dentist often remains in the path of light, which minimizes the effectiveness of aerial lighting. Various dental tools have been provided with a light source to assist the dentist during various dental activities. For example, a typical dental drill includes a bundle of optical fibers that transmits light from a light source to the end of the dental bur that allows the dentist to provide light directly to the area where drilling or drilling occurs. Representative of this technology are the restrictions shown in the U.S. patent. No. 4,507,085 (Mosimann) and U.S. Pat. No. 5,088,924 (Woodward). Handpieces with a dental syringe tip have also been provided with a light source to illuminate the area in which air and / or water will be sprayed. Representative of these devices is the description of the US patent. No. 4,619,612 (Weber) showing a bundle of optical fibers arranged in the center of a metal syringe tip structure. A lighting bulb acts as the light source and is placed inside the handpiece. The syringe tip used in the Weber patent description is a non-disposable metal syringe tip that must be autoclaved before use with the next patient. Prior to the present invention, however, there have been no tips of disposable syringes that are provided with a light source to transmit light to the oral cavity. Dentists who use disposable syringe tips had to resort to ambient air lighting systems, used in dental offices to see into the patient's oral cavity while using the handpiece with air dental syringe tip / Water.

An object of the present invention is to provide a useful source of light that can be transmitted to the oral cavity of the patient when the dentist is using a handpiece with air / water dental syringe tip. It is a feature of the present invention to provide a light source at the end and tip of the syringe inside the adapter holding the syringe tip in the handpiece with a dental syringe tip. The light from the source is directed at one end of the syringe tip and transports over its length. At an opposite end of the syringe tip, light radiates from the syringe tip and can be used to illuminate the oral cavity of the patient. An advantage of the present invention is that a dentist will be able to illuminate the oral cavity using the same instrument he is using to supply air, water or air and water in combination to the oral cavity of the patient. Any dental procedures that require use of the handpiece with air / water dental syringe tip can be carried out easier and safely and effectively, because the dentist will be able to see exactly where it is working in the oral cavity . Other objects, features and advantages of the present invention will be apparent from the consideration of the following detailed description. COMPENDIUM OF THE INVENTION A handpiece structure with a dental syringe tip includes a transparent, plastic syringe tip mounted on an adapter for connection to the handpiece. Inside the adapter at a site adjacent to the end of the syringe tip, a light source, preferably a light ring based on optical fibers, is provided. The light from the source will be transmitted along the tip of the syringe and will emit from its end. By placing the end of the syringe tip in the oral cavity of the patient, the dentist can provide illumination in the oral cavity, such that various dental functions can be performed more easily and accurately. A special handpiece body formed of an indoor handpiece unit and an outer cover is provided to receive the adapter in the syringe tip structure. The air, water and fiber optic lines are placed inside the body of the handpiece. The handpiece body can be easily closed for cleaning. The light source can also be a light bulb placed on the back of the adapter. The adapter is made of transparent or at least translucent material, so that the light from the light bulb will be transmitted through the adapter and then into the syringe tip. In yet another embodiment of the present invention, the light source may be one or more bundles of optical fibers placed through a valve head and manifold structure. The ends of the fiber optic bundles are placed adjacent to the end of a syringe tip, such that the light emitted from the ends of the fiber bundles is transmitted to the tip of the syringe which then transports the light onto its end. length and light is emitted from the tip of the syringe tip and can be used to illuminate the oral cavity of a patient.

DETAILED DESCRIPTION OF THE PREFERRED MODALITIES The illuminated dental syringe tip hand piece stucture of the present invention is generally illustrated at 300 in FIG. 1. A handpiece body 312 comprises an outer cover 410 that is slidably mounted on a indoor unit 430. The indoor unit 430 is a generally U-shaped channel having a hollow interior to accept the water line, the air line and the fiber optic line. Each of these supply lines are connected to the hand piece body 312 by an outer pipe 470 extending to the sources (not shown) of the water supply, the air supply and the light source for the fiber lines optical An adapter 320 mounting the syringe tip is provided at one end of the handpiece body 312. 314 in the hand piece body 312. A locking lid structure 330 holds the syringe tip 314 securely in place. As illustrated in Figures 2, 3 and 5, the handpiece body 312 has at one end a threaded opening 313 in which the adapter 320 can be threaded using the first adapter threads 322. The adapter half 320 is provided. with a central hexagonal opening 316 in which a key can be positioned to tighten the adapter 320 in the threaded opening 313 of the handpiece body 312. In the embodiment shown in this application, the handpiece body can be of standard configuration known as the "continental design" although the components of the present invention can be modified to adjust any body configuration of the handpiece. Additional details to the adapter 320 are set forth in U.S. Pat. No. 5,049,071 which is incorporated herein by reference. An interlocking structure securely holds the syringe tip 314 in the handpiece body 312, to prevent accidental loosening of the syringe tip 314, such that the air and water supply are all the time fed through the syringe tip 314 and to prevent syringe tip 314 from separating from adapter 320. The locking structure generally comprises adapter 320, a collar holding member 340 that fits over the outer end of adapter 320, an o-ring 342 and a locking cap 330, which is threaded into the adapter 320 and encircles the collar holding member 340. The interior of the interlock 330 contains a set of threads 332 which cooperate with the second adapter threads 326 in the adapter 320, for clamping the interlock cover 330 to the adapter 320. Additional details in the interlock structure are illustrated in the patience of the E..UA No. 5,306,146 and the US patent. No. 5,489,205, both of which are incorporated herein by reference. The release of the locking cap 330 from the adapter 320 removes pressure from the collar holding member 340, which allows removal of a used syringe tip and replacement with a new syringe tip. The tip of syringe 314 is a cylindrical member. elongated, preferably made of a plastic material. The syringe tip 314 is snapped onto the tapered spindle 321 of the adapter 320. Additional details of the syringe tip are set forth in U.S. Pat. No. 5,049,071. The tip of syringe 314 should be made of materials that transmit light from one end of the syringe tip to the other end. In the preferred embodiment of the present invention, the tip of syringe 314 is made of polypropane, although other plastic light transmitting materials can be used such as acrylic plastics. Also, the tip of syringe 314 preferably should be transparent or clear, such that an inspection of the syringe tip will reveal if it has previously been used. Once a syringe tip has been used on a patient, the tip of the syringe tip will retain small amounts of saliva, blood or other materials from the patient's mouth. The tip of syringe 314 is designed to be disposable after a single use. The tip material is manufactured in a single stage extrusion process and is preferably made from any rigid transparent plastic material that can transmit light. A rigid plastic is preferred to cover the need to use the tip for continuous retraction of the cheek and tongue by the dental operator. The syringe tip 314 is snapped onto the tapered spindle 321 at the end of the spindle extension 325. The tapered spindle 321 integrally connects to a spindle extension 325 that extends through the rear end of the adapter and into the spindle. handpiece body 312. The rear end of the spindle extension 325 is threaded and received by the threaded opening 316 inside the handpiece body 312. The remote end of the spindle extension 325 is connected to the water supply line 444, which allows water to be fed to syringe tip 314 in a conventional manner. Similarly, the air supply is sent to the adapter 320 through the air supply line 442 in the handpiece body 312 which aligns with the air channel 328 in the adapter 320. As illustrated in Figures 2 and 3 , a light source in the form of a fiber optic light ring or fiber optic ring lamp 360, are placed directly adjacent the end of the syringe tip 314 inside the adapter 320, so that it is directed light by the length of the syringe tip. In the preferred embodiment of the present invention, a fiber optic ring lamp made by Fiberoptics Technology Incorporated, of 14 Fiber Road, Pomfret, CT 06258, may be employed, although any suitable fiber optic ring structure will be acceptable. The fiber optic ring lamp 360 is connected to a fiber optic bundle 373 that extends through a passageway 448 in the handpiece body 312 to connect to a remote light source (not shown). Inside the adapter 320, an annular washer 365 is provided which receives a flexible quick coupling ring 378. This flexible ring 368 encloses the spindle extension 325 and the optical fiber bundle 373 and holds them in place inside the adapter 320. As illustrated in Figure 2, with the locking cap 330 pushed over the adapter 320 in the closed position, the fiber optic ring lamp 360 abuts adjacent the end of the syringe tip 314 inside the adapter 320. When the power supply is activated by the dentist, the light bulb 360 will illuminate and the light from there will pass over the length of the syringe tip 314 to its remote end where it is emitted to illuminate the patient's oral cavity. Figure 4 shows the interior details of the indoor unit 430 of the handpiece body 312. Inside the unit 430 within the U-shaped channel, the water supply line 444 and the water supply line 444 are provided. 442 air, which supply air and water from the source to the adapter. The water valve 454 is placed in the water supply line 444 and activated by the dentist by pressing the water button 453 which is transported by the outer cover 410. Similarly, the air valve 452 is placed in the line of water 454. 442 air supply and is activated by the dentist, by pressing the air button 451 carried by the outer cover 410. The indoor unit 430 is also provided with a conventional pin holder 462 which cooperates with an opening 464 in the outer cover 410. The outer cover 410 is slid over the length of the inner unit 430 and the pin holder 432 engages the opening 464, to hold the outer cover 410 in place when the structure is employed. When it is desired to clean the structure, the pin holder 462 is depressed which allows the outer cover 410 to slide out of the indoor unit 430. The adapter 320 is unscrewed from the body of the handpiece 132 and the outer cover 410, the adapter 320, the locking cap 330 and the collar holding member 340 can then all be cleaned and subjected to auto key as required. Figure 6 shows a modification to a syringe tip 514 which ensures that the syringe tip is placed precisely on the adapter 320. The syringe tip 514 has a central water passage 522 and a plurality of air passages 524 positioned around the water passage 522. One end of the syringe tip 514 is provided with a keyed channel 530 that aligns with a complementary adapter insert 540 (Figure 2) inside the adapter 320. In this way, for the syringe tip 514 sits properly within the adapter 320, the keyed channel 530 in the syringe tip 514 must align with the adapter insert 540. If the alignment is not correct, the adapter 514 will not properly adjust the pressure on the spindle 321 and problems of leakage of water and air. Other variations of the present invention may be made. Instead of the optical fiber illumination ring 360, other suitable light sources can be employed. For example, any conveniently shaped light bulb can be placed inside the adapter, such that light can then be transmitted through the syringe tip and into the oral cavity of the patient. As illustrated in Figure 7, the handpiece body 612 has an adapter 620 that mounts the syringe tip 614 to the handpiece body 612. In this embodiment, the adapter 620 is made of relatively hard plastic such as polycarbonate or hard acrylics. The adapter 620 should also transmit light from a light source 660 to the syringe tip 614, such that the material selected for the adapter 620 should be a light transmitting material. It is preferred that this material be a clear, clear plastic, but a translucent material may also be employed. The adapter 620 rests on one end of the handpiece body 612 and a locking ring 650 having an external locking ring thread 652 cooperates with a set of internal threads 622, holds the adapter 620 in place. The locking ring 650 may have a recessed slot (not shown) on its surface for receiving a screwdriver to rotate the locking ring 650 on the internal threads 622. The adapter 620 includes a tapered spindle 621 on which the syringe tip 614 it is mounted. A water channel 628 and an air channel 629 are provided in the adapter 620 for transmitting water and air respectively from the handpiece 612 to the syringe tip 614. An interlocking structure securely holds the syringe tip 614 in the body of hand piece 612, to prevent accidental loosening of syringe tip 614, such that the point of air and water at all times is fed through syringe tip 614 to prevent syringe tip 614 from separating of the adapter 620. The locking structure generally comprises the adapter 620, a collar holding member 640 which fits on the inner end of the adapter 620, an O-ring 642 and a locking cover 630 which is screwed on the adapter 620 and circumscribes the collar fastening member 640. The interior of the locking cap 630 contains a set of threads that cooperates with the second threads of the adapter 626 in the adapter 620to hold the locking cap 630 on the adapter 620. The adapter 620 contains a bulb recess 625 which receives the light bulb 660. The light bulb 660 is mounted on a light bulb base 662 placed on the handpiece body 62. The base of the light bulb 662 is connected to a remote power supply (not shown) when connecting the 660 wire. When the 660 light bulb is activated by the power supply, a 668 lens concentrates the light on the adapter 620 so that the light is transmitted through the adapter 620 and towards the tip of the syringe 614, for transmission to the patient's mouth. It is convenient to minimize the heat emitted from the light source, so that fluorescent lighting or optical fiber structures are preferred since the heat sections of these light sources are minimal. It is also contemplated that a light source positioned adjacent a reflective surface may be employed to focus light at the end of the syringe tip. This will increase the intensity of light without increasing the size of the light source and will increase the intensity of light available for transmission by the length of the syringe tip. As illustrated in Figures 8 to 12, another embodiment of the present invention utilizes one or more fiber optic bundles to deliver light from a light source through the handle of the syringe tip structure at the syringe tip, where the light is transmitted by the length of the syringe tip and used to illuminate the patient's oral cavity. The dental syringe structure of this embodiment is generally illustrated at 700. The handle 712 contains the connecting lines for optical fiber bundles 76 and for the sources of air and water which are water pipes 756 and air pipe 758. The handle 712 is screwed (or otherwise conveniently connected) to a head 720 having a threaded extension 722. The head 720 also contains the air valve 752 and the water valve 754 for air and water activation respectively in a conventional manner. As illustrated in Figure 9, the threaded extension 722 includes one or more fiber optic bundle apertures 728, for receiving one or more of the fiber optic bundles 170 as well as a spike or water tip attachment 724 for connecting the water pipe 756 and an air tip attachment 726 for connecting the air pipe 756. The head 720 is also threadedly connected to a lug nut 740, which is operable in connection with an interlock collar 750, securely held the tip of syringe 714 in place in the dental syringe structure 700. The structure of the lug nut 740 and the locking collar 750 is illustrated in the US Pat. No. 5,306,146 and the U.S. Patent. No. 5,489,205, the descriptions of which are hereby incorporated by reference. A body 360 is placed inside the head 720. The multiple body 770 is a generally cylindrical body that includes a tapered spindle 780 (see Figure 10) on which the syringe tip 714 is mounted in the manner shown in the Patent. of the USA No. 5,236,356. A manifold top 772 is positioned near the manifold body 770 and held there by a manifold sleeve 776. The manifold body 770 contains the fiber optic bundle apertures 728 for receiving the bundles of optical fibers 760. The air supply for the dental syringe structure 700 is connected to the inner air rod 778 which in turn is mounted in the air vein 782 which is a longitudinal passage through the manifold body 770. The water supply for the dental syringe structure 700 it is connected to the water insert rod 779, which in turn is mounted in the longitudinal water vein displaced 790 in the manifold body 770. The displaced longitudinal water vein 790 intersects a vein perpendicular water 788 in the manifold body 770 which also intersects the axial water vein 786 in the manifold body 770 which finally intersects with a central longitudinal water vein 784 in the body or manifold 770 for supplying water to spindle 780 and thence to syringe tip 714. Figure 10 shows in longitudinal cross-section the structure of dental syringe 700 in assembled relation. A head 720 is screwed into the handle 712 and the combined multiple body 770, manifold top 782 and manifold sleeve 766 are received in a recess in head 720. Latch nut 740, when threaded in head 720 holds manifold body 770, manifold cap 772 and manifold sleeve 776 in place with an O-ring 742 that is provided to seal this threaded connection. The syringe tip 714 is pushed into the lug nut 740 and one end presses onto the spindle 780. The syringe tip 714 is securely held in the spindle 780 by the locking collar 750 and the O-ring 751, when the nut of the thumb 740 is screwed on the head 720. The end of the syringe tip 714 is placed near the ends of the optical fiber bundles 760, such that when the light source (not shown) is activated, the light transported by bundles of optical fibers 760, it is transmitted to the tip of syringe tip 714 and transported over the length of syringe tip 714 where it can be emitted into the patient's oral cavity to provide required illumination. Any convenient means can be used to activate the light source. At the same time that the light is activated, the dentist can press the air valve 752 which causes the air in the air line 758 to pass through the air vein 782 and into the air passages in the tip of the syringe 714 Similarly, activation of the water valve 754 causes the water in the water pipe 756 to pass into the displaced longitudinal water vein 790, thence to the perpendicular water vein 788, thence to the axial water vein 786. and thence to the central longitudinal water vein 784 which connects to the central passage in the spindle 780 which feeds water to the central water passage of the syringe tip 714. While the invention has been illustrated with respect to several specific embodiments of the same, these modalities will have to be considered as illustrative instead of limiting. Various modifications and additions can be made and will be apparent to those skilled in the art. Accordingly, the invention will not be limited by the foregoing description but rather will be defined only by the appended claims.
