Definitions

  • the invention relates to a dental handpiece that can be connected to a supply hose, with a handle part that can be rotated relative to the supply hose for fastening a working part that carries a tool, and with devices for light and image transmission, a transducer in a rotationally fixed connection with the handle part stands, which converts the images supplied by the device for image transmission into electrical signals and delivers them to at least one line running along the supply hose.
  • the handpiece itself can only be sterilized in an autoclave, because if the chemical treatment (alcohol) is too long, especially rubber parts such as e.g. Sealing rings, would be damaged.
  • the CCD cameras currently used as signal converters would be damaged in the autoclave.
  • the invention provides that the transducer is arranged so that it can be removed from the handle at a location that is accessible from outside the handle part.
  • the transducer detachable various options are shown for making the transducer detachable, it also being possible to detachably attach the device for light and image transmission, which are expediently arranged in a common tube, together with this tube to the handpiece .
  • the detachability of the image converter is also advantageous insofar as it enables the handpiece to be used even without the device according to the invention.
  • the application of the basic idea of the invention to differently constructed handpieces is subsequently explained using several exemplary embodiments in the drawings. In these shows
  • FIG. 1 a shows a vertical longitudinal section and the associated cross sections according to lines I-I and II-II
  • FIG. 1 b shows the individual parts of the device according to FIG. 1 a
  • 2a is the partially sectioned side view of a second exemplary embodiment
  • FIG. 2b shows the individual parts of the device according to FIG. 2a.
  • 3a and 3b correspond to FIGS. 2a and 2b for a further exemplary embodiment.
  • 4a is the partially sectioned side view of a fourth exemplary embodiment, the individual parts of which are shown in FIG. 4b.
  • 5a and 5b correspond to the representation of Fig. 4a and 4b for a fifth embodiment.
  • 6a shows an enlarged view of the end region of the handle part 1 and FIG. 6b the associated cross section.
  • the dental handpiece shown in FIG. 1 has an angled handle part 1, with which various work tools can optionally be connected, which consist of a neck part 14 and a head part 17 and carry a rotating tool 15.
  • the tool 15 is driven by a motor 5, which is designed as a lamella motor, to which driving air is supplied via the supply hose 3.
  • the supply hose 3 can be rotated relative to the handle part 1 or its rear connecting piece 22.
  • Bracket 12 for the subsequently described in detail light generating and image converter part must be arranged non-rotatably relative to the angled handle part 1. If this holder projects over the cross section of the handle part 1 as in the case of the exemplary embodiment according to FIG. 1, it is also necessary to move it as far as possible to the end of the handpiece. This results in the arrangement shown, in which the holder 12 comprises the supply hose 3 with elastic legs 7, which allow the holder 12 to be easily removed and clipped on.
  • an incandescent lamp 10 Arranged in the holder 12 is an incandescent lamp 10, which supplies the light guide 11, which are guided through the tube 4 and ends in the manner shown in FIG. 6 at the front end of the handle 1.
  • an image of the surroundings of the front end of the handpiece is passed to the transducer 2 via a lens system known from conventional endoscopy, which is designed as a so-called CCD camera, that is to say converts the optical image into electrical signals.
  • These signals are transmitted via sliding contacts 13 to the circumference of the supply hose 3 and from there to the multi-core line 9, which leads through the supply hose 3 to a computer, which composes an image from the signals, which is stored or on a screen can be played.
  • both the tube 4, which contains the devices for light and image transmission, and the holder 12 for the transducer 2 are detachably connected to the handle part 1, so that they are separate from the other parts of the Facility can be sterilized by placing it in alcohol.
  • the tube 4 is to be pulled out of the envelope 18, the Pull the holder 12 off the supply hose 3 with the legs 7 spread apart. Since the sleeve 23 can be rotated with the supply hose 3 relative to the handle part 1, the non-rotatable connection of the holder 12 to the handle part 1 is conveyed through the tube 4 in the assembled state.
  • the device according to FIG. 2 differs from that according to FIG. 1 mainly in that the motor 5 is designed as an electric motor, which is connected to the supply hose 3 in a rotationally fixed manner.
  • the rear end of the angled handle part 1 completely surrounds the electric motor.
  • the converter 2 and the incandescent lamp 10 are arranged here in a rotating ring 8 which surrounds the supply hose 3 continuously.
  • the removal of the transducer 2, which is presupposed in FIG. 2b, takes place here in that the CCD camera is removed from a plug-in base mounted in the rotating ring 8.
  • the rotating ring 8 is secured against rotation relative to the handle part 1 here by direct connection of the handle part 1 and rotating ring 8, but of course also by the removable tube 4.
  • FIG. 3 shows only slight differences from that according to FIG. 2.
  • This is a standardized clutch system, the so-called ISO clutch.
  • the supply hose 3 and the housing 6 of the motor can be rotated relative to one another here.
  • the housing 6 is rigidly connected to the handle part 1 during operation.
  • the non-rotatable securing of the rotating ring 8 can also be mediated by the housing 6 apart from the tube 4.
  • the housing 6 enclosing the motor is rigid with the handle part 1 connected.
  • the rotating ring containing the transducer 2 is here, however, between the sleeve 6 and the handle 1, so that its ' rotationally fixed fixing is not a problem.
  • the sliding contacts between the mutually rotatable parts of the line 9 are not located on the holder of the transducer 2, but in the housing 6 on the one hand and on the supply hose 3 on the other hand.
  • the incandescent lamp 10 is arranged in the angled handle 1, specifically in front of the CCD camera 2, which is why the tube 4 branches in order to accommodate the light guides 11 on the one hand and the image transmission apparatus on the other hand.
  • the ring 24 serving as a holder for the converter 2 is non-rotatably mounted on the pin 25 with which the motor part projects into the handle part 1.
  • the rotating ring 8 receiving the transducer 2 is seated between the handle part 1 and the housing 6 of the motor for the handpiece.
  • the supply hose 3 is firmly connected to the housing 6, so that the rotating ring 8 permanently arranged in the housing 6 must be held in position, for example by the tube 4 and the lamp 10 arranged in the handle part 1, so that the image transmitted through the tube 4 correctly falls on the converter 2.
  • the necessary slip clutch is located here on the end face of the part surrounded by the sleeve 6.
  • the image transmission device used is state of the art in the field of endoscopy. 6 therefore only the sleeve 23 is shown, which surrounds the corresponding lens system.
  • This lens system is arranged together with the light guides 11 in the tube 4, which, as mentioned, can be removed from the handle part 1.
  • the light exit point which is shown in FIGS. 6a and 6b, is in the immediate vicinity of the front end of the handle part 1, where cooling air supplied through line 19 and cooling water supplied through line 20 are mixed to form a spray which is at the end of the handle part 1 exits.
