Each of the tools and coupling device having a bore therein for conducting pressurized water from said hand-piece for supplying water to the area of the tooth contacted by the tip portion of the tool and including a pair of typical tools for tooth treatment.
5 Claims, 9 Drawing Figures PATENTED W21 1912 SHEEI 1 [1F 2 I "Inn-"9 INVENTOR. SEYMOUR ROBINSON ULTRASONIC DENTAL HAND-PIECE WITH DETACHABLE TREATMENT TOOLS This invention relates in general to dental treatment apparatus and more particularly to an ultrasonic handpiece provided for interchangeable treatment tools having a variety of tips for tooth cleaning and treatment. Each of said tools having a bore therethrough for conducting pressurized water supplied by the handpiece to the tool and directed thereby to the area .of treatment of each tooth.
Prior dental cleaning and treatment tools for hand operation required a high degree of skill and care when used by the dentist or hygienist. Furthermore, prior .ultrasonic devices do not provide for interchangeable tools having different tips for the many purposes required and were not detachably coupled to a handpiece without excessive loss of ultrasonic energy.
These prior tools had no built-in means for supplying flushing water directly to the treatment areas.
The present invention overcomes the above objections and disadvantages by'the provision of a handpiece in which a detachable coupling means is provided in the hand-piece for engaging interchangeable tools having different treatment tips without serious energy loss of ultrasonic energy from the transducer, including the provision of a water passage through the tool for providing treatment in the presence of a water supply directed at the area treated. 7
Reference is had to applicants pending patent application, entitled Ultrasonic Tooth Cleaning Apparatus, Ser. No. 7,607. I
These and other objects and advantages in one embodiment of the invention are described and shown in the following specification and drawings, in which:
FIG. 1 is a perspective illustration of an ultrasonic hand-piece and energizing unit therefor.
FIG. 2 is an enlarged cross sectional side elevation taken through section line 2-2, FIG. 1.
FIG. 3 shows a coupling for detachably securing a tool in the hand-piece shown in FIG. 1.
FIG. 4 is a perspective view of the coupling and tool disengaged from the hand-piece shown in FIG. 3.
FIG. 5 is an alternate form of coupling for detachably securing a tool in the hand-piece.
FIG. 6 is a fragmentary top view of a right hand treatment tool of the character shown in FIG. 3.
FIG. 7 is a fragmentary bottom plan view of the tool shown in FIG. 6. v
FIG. 8 is a fragmentary side view of a left hand treatment tool of the character shown in FIG. 3.
FIG. 9 is a fragmentary bottom plan view of the tool shown in FIG. 8. v
Referring to FIG. 1, an ultrasonic hand-piece assembly l is connected to an electronic ultrasonic generator assembly 2 by a flexible tube 3 which is adapted to conduct water and includes a pair of electric ultrasonic output conductors 4 and 5, which tube and conductors are removably secured to the unit assembly 2 by a dual coupling 6.
The ultrasonic generator includes a power cord 7 with a plug 8 for attachment to a source of electric energy and a tub 9 adapted to be connected to a source of controlled pressurized water. The generator also includes an on-off switch 10, an ultrasonic intensity control 11, an on-off signal light 12 and water flow indicator 13.
Referring to FIG. 2, the hand-piece consists of a plastic molded body member 14 and a plastic heel piece 15, secured together by well known means, which serves as an inlet junction for the conductors 4 and 5 and the tubing 3. A tubular ceramic ultrasonic transducer 16 has the rear end thereof positioned against a flange 17 in the heel piece 15 and is axially centralized in the body member 14 by an O ring 18 resting against a ring 19 positioned around the inner periphery of the body member. The opposite outer end portion of the transducer 16 is spaced from the bore in body member 14 by an elastomer tube 20.
The tubular transducer 16 consists of one of the well known synthetic ceramics, such as barium titanate, and the bore and the outside surface are independently coated with metal, thus providing a capacitive reactance load.
The water supply tubing 3 is connected to a nipple 21 in the heel piece which has a bore 22 therethrough for conducting pressurized water to the coupling of the tool. The electrical conductors 3 and 4 are secured to an external contact spring 23 and an internal spring 24, respectively, as shown, for energizing thetransducer. The inner end of the nipple 21 is threaded to a plastic tube 25 and sealed thereto with a spacer 26 and an 0" ring 27. The tube 27 has a bore 28 therethrough connecting the bore 22. An additional-0" ring 29 aligns the tube 25 and a smaller 0 ring 30 is secured in the outer end of the tube 25 to seal a portion of the coupling, to be hereinafter described.
Referring to FIG. 4, one of a particular form of tool 31 is provided'with a cylindrical coupling member 32 which includes an integral coaxial flange 33 and stem 34. A coupling member includes a coaxial bore 35 which extends through the entire shank of the tool and exits into a channel 36 in the tip portion of the tool. A generally cylindrical guard 37 has external threads at one end thereof for engaging internal like threads in the body for retaining the tool by means of the coupling thereon.
Again referring to FIGS. 2 and 3, the circular planar face of the coupling member 32 is urged against the outer end of the transducer 16 by a coil spring 38 bearing against flange 33 with alignment washers 39 and 40 on each side thereof with the outer washer bearing against a shoulder 41 in the bore of the guard 37. An elastomer grommet 41 is retained in the end of the guard 37, which provides sealed but free reciprocation of the shank of the tool 31 through the guard 37 It is now apparent that when the coupling is positioned against the end of the transducer, as shown in FIG. 3, and the guard 37 threaded into the body member 14, the tension of the coupling against the transducer may be varied corresponding to the desired ultrasonic amplitude of reciprocation of the tool when the handpiece is operated.
It is also apparent from FIGS. 2 and 5 that the pressurized water supplied by tubing 3 will flow through nipple 21, plastic tube 25 and through stem 34 and into the bore 42 of the tool, which water will be guided by channel 36 directly to the work area of the point of the tool.
Referring to FIG. 3, it is of great importance that the outer end of the transducer 16 and the mating face of the coupling member 32 be precisely flat and in overall contact to prevent erratic operation of the device or possible fracture of the ceramic transducer and to this end the following alternate construction is shown in FIG. 5, which shows the same coupling member 32 having a soft metal washer 43 positioned between the end of the transducer 16 and the face of the coupling member, and a further alternate by replacing the spring 38 with a resilient plastic washer 44, such as Teflon or nylon. Thus, if the metal washer 43 is made from zinc, copper, or other soft metal of uniform thickness, the precise machining of the end of the transducer and the face of the coupling member is avoided. Furthermore, the replacement of the spring 38 by a resilient plastic washer 44 eliminates the need for the more tedious adjustment of the spring urged coupling. I
FIGS. 6 and 7 illustrate a desirable tip R for the tool 31 having a generally V shape angled to the right for treatment of the lower right and upper left teeth of a patient.
FIGS. 8 and 9 illustrate the same style tip L as shown in FIGS. 6 and 7 except angled to treat the left lower and right upper teeth of a patient.
In operation, one of several tools, such as the one shown in theflgures, is secured in the hand-piece by threading the guard 37 therein and energizing the ultrasonic generator by connection to a source of power and a source of pressurized water and then by moving the switch 10 to the on position, the tool and the tip thereof will reciprocate at an ultrasonic frequency under the control of knob 11 and a desired amount of water will flow by the adjustment of a well known valve means, not shown.
It is to be understood that certain modifications in construction are intended to come within the scope and teachings of the above specification.
