Definitions

  • the invention relates to a battery light source of the type mentioned in the preamble of claim 1.
  • Such a battery light source is known from US 6,135,947A. It is used to feed light into the illumination system of an endoscope, in which a light guide passes through the shaft of the endoscope in conventional training, to emit light at the distal end of the work area to be considered.
  • the light guide At the proximal end of the shaft of the endoscope, the light guide has an optical waveguide connection, to which light sources can be connected.
  • This can be, for example, an external light source, which can be connected via a light conductor connection cable to the light conductor connection of the light guide in the endoscope.
  • a small handy battery light source is used, which can be attached directly to the endoscope to the light guide connection of the light guide with a corresponding coupling and battery-powered generates the required light.
  • Generic battery light sources are used for medical purposes, including in the sterile environment of surgery.
  • the endoscope used must be sterile.
  • the battery light source, which is connected directly to the endoscope must be sterile.
  • the well-known battery light source is, as usual with the endoscopes, reusable and therefore formed sterilizable. This includes extensive sealing measures on the housing and at its openings, for example the opening for inserting new batteries. It results from a very complex and expensive construction.
  • the object of the present invention is to provide a battery light source of the type mentioned, which ensures high patient safety at low cost.
  • the battery light source according to the invention is designed for single use.
  • the battery arrangement consisting of one or more batteries is connected to the housing in such a way that, for example, it is enclosed in such a way that it can not be removed without destroying it, ie only by destroying the housing or the battery. This results in opportunities for significant cost savings and reuse after replacement of the battery is prevented.
  • the light source is connected to the battery assembly with a permanent connection, with no possibility of interrupting the circuit during normal operation. This can be, for example, a firm soldering. Mechanically frequently exchanged contacts can be saved.
  • the switch need only be turned on once to turn on the battery light source at the beginning of the operation. Thereafter, a re-actuation of the switch is no longer necessary and not desirable. After switching on the bulb burns therefore until the battery is empty. Replacing the battery is also not possible.
  • the result is a design that is optimized for single use, offers significant savings and also safely prevents accidental reuse.
  • the housing has a predetermined breaking point.
  • the housing can be opened by destruction to remove the battery assembly, which is advantageous for purposes such as proper waste separation, but can not be misused to insert a new battery.
  • the housing is advantageously made of plastic according to claim 3, which allows a particularly cost-saving design.
  • the plastic can be insulating be so that separate insulation accounts.
  • the plastic may be pourable or sprayable, thus providing opportunities for simplified mass production.
  • the lamp is advantageously designed according to claim 4 as a light emitting diode. This allows a power-saving design with high quality light and structurally good mounting options.
  • the switch is advantageously designed according to claim 5. He uses the usual technology of disposable power switches, such as those often used in small electronic devices that are shipped from the factory with a battery inserted. This in turn results in significant cost reduction opportunities on the way to creating a single-use battery light source that offers significant cost advantages over the usual reusable battery light source. Moreover, such a switch can not be switched off and on again with high safety.
  • Figure 1 is a side view of an endoscope with attached inventive battery light source
  • FIG 2 is an enlarged view of the battery light source of Figure 1 in
  • FIG. 1 shows an endoscope 1 with a shaft 2, at the proximal end of which a main body 3 is arranged, from which an optical waveguide connection 4 leaves.
  • a battery light source 5 is plugged into the light guide 4, which will be explained in detail with reference to FIG 2.
  • the battery light source 5 has an existing plastic, for example, by injection molding produced housing 6, in the interior of a battery assembly consisting of two batteries 7 is arranged.
  • the batteries 7 are connected in series, wherein they are connected at one end of the battery assembly with a contact piece 8 which is pressed with a spring 9.
  • a control device 10 which is contacted on its other side by contacts, not shown, of a lighting means in the form of a light emitting diode 1 1.
  • the control device 10 is used, for example, the lighting diode 1 1 to provide the appropriate operating voltage.
  • the housing 6 is made in one embodiment of two parts namely a main part 6a and a lid 6b, which are assembled after introduction of the light-emitting diode 1 1, the control device 10 and the batteries 7 and inseparably connected, eg by gluing, welding or by one or more non-accessible from the outside locking tongues.
  • the spring-mounted contact piece 8 is preferably arranged in the lid 6b.
  • the light-emitting diode 1 1 is located with the recognizable from Figure 2 lens part against an opening 12 of the housing 6, which serves as a coupling to the light guide 4 of the endoscope 1 and for this purpose, for example, has an internal thread which is screwed onto an external thread of the light guide terminal 4.
  • a light-emitting diode with attached lens instead of a light-emitting diode with attached lens, alternatively, a light-emitting diode without patch lens can be used.
  • an optionally required lens can be formed integrally with the housing 6, for example by 2-component injection molding. As Figure 2 shows, results in a very simple construction. All components of the battery light source 5 are held together by the housing 6 and held in the required mounting position, for example, in the illustrated position of the light emitting diode 1 1 with the opening 12 aligned LED 1 1.
  • the light-emitting diode 1 1 illuminates the indicated in Figure 2 in the interior of the optical fiber connection 4 optical fibers which run from Lichtleiteran- circuit 4 forth through the main body 3 in the shaft 2 of the endoscope 1, with its front end in the distal end face of the shaft 2 lying to be able to radiate light into the surgical field.
  • the battery light source 5 shown must be able to tolerate longer storage times from its production to use in the operating room, in which the batteries 7 are not to be discharged. It therefore requires a power switch, which is actuated only once.
  • a foil strip 13 is provided which is arranged between one of the batteries 7 and the contact piece 8 insulating and protrudes through an opening slot 14 in the housing 6 to be pulled out to start up the battery light source 5 can.
  • the battery light source 5 After completed single use the battery light source 5 is disposed of. This requires the proper separation of the batteries 7 from the rest of the unit.
  • the housing 6 must therefore have an opening possibility. This is created in a structurally outermost simple manner with the aid of a housing 6 circumferential groove 15, which allows a simple breaking of the housing 6 for the purpose of removal of the batteries 7 in terms of a predetermined breaking point.
  • the pointing in the direction of the coupling part of the housing 5 may have gripping aids in the form of a knurling or handle webs, on the one hand to simplify the assembly and disassembly of the battery light source on the endoscope and on the other hand, the breaking of the housing.
