Definitions

  • the invention relates to a bipolar resectoscope referred to in the preamble of claim 1 and a carriage and a cable for it.
  • Bipolar resectoscopes are used for surgical work, especially in urology, but e.g. also used in gynecology. They have an electrode arrangement which carries in the distal end area for tissue processing serving exposed electrodes, which are connected to a high-frequency generator in order to apply the electrodes required for working high-frequency voltage.
  • the resectoscope has a longitudinally displaceably mounted carriage, on which the electrode arrangement is fastened with a proximal end region. By moving the carriage in the longitudinal direction can thus be generated when working with the electrode assembly required longitudinal movement. On the carriage, the electrical contact between the conductors of the electrode assembly and the cable leading to the high frequency generator is made.
  • CONFIRMATION COPY Monopolar resectoscopes have only one conductor and have an active cutting or coagulating free electrode.
  • the conductor is connected to one pole of the high-frequency generator.
  • the second pole of the high-frequency generator is contacted over a large area with the patient's body at a great distance from the operating area via a return electrode. This operation involves disadvantages, mainly due to the current flowing uncontrolled between the electrodes for a long time through the body.
  • Bipolar resectoscopes have two conductors and two electrodes, with the electrodes connected to the two conductors connected to the two poles of the high frequency generator and located adjacent to the distal end of the resectoscope.
  • the current flows on a short path between the electrodes. This is done in a highly conductive liquid.
  • US 6,974,458 B2 shows a generic construction in which a two-wire cable has both plug contacts in a plug which is inserted with a bore in the longitudinal direction of the end portion of the electrode assembly.
  • This is an extremely simple construction that also has seals for the contacting areas to keep out moisture.
  • Of great advantage in this direct contacting is also the direct contact between the plug connector arranged on the cable connector and the contact surfaces on the electrode assembly. Is there in the contact area disorders, z. B. by scorching, so the electrode assembly is replaced since, which is the case anyway after every operation, and the cable is replaced with the plug, which does not cause any major costs. All faults can be eliminated completely.
  • this known construction has the disadvantage that the plug must be plugged in the longitudinal direction.
  • Another disadvantage is the cramped spatial conditions on the plug. Because of the cramped spatial conditions, the plug can not be provided with an ergonomic large handle. The assembly is therefore complicated and the closely adjacent arrangement of conductors and contacts, which are located at different poles of the high-frequency voltage, leads to further problems.
  • DE 202005013853 U1 likewise shows a monopolar resectoscope in which the cable connector makes contact with an intermediate contact element on the carriage, which in turn contacts the contact surface of the electrode arrangement.
  • This indirect type of contacting has fundamental advantages in terms of seal and encapsulation of the contact points and the further advantage that the plugging sequence is arbitrary. It can therefore be inserted first the electrode assembly and then the cable connector, or vice versa, which is not possible in the direct contacts described above.
  • the object of the present invention is to reduce the contact problems in the generic bipolar urological resectoscope.
  • the first contact surface is connected to an intermediate contact element, which in turn is first contacted by the plug contact.
  • So here is an indirect contact.
  • the second plug contact contacted the second contact surface directly. So here is a direct contact.
  • the first plug contact the advantages of indirect contacting can be used, so the solid, especially reusable construction that allows good fluid seal and insulation.
  • the second plug contact which is arranged on the second plug of the cable, can be kept very simple and contact the electrode arrangement without special sealing measures. It has been shown that sealing and insulation is not so much required by the plug contacts to the outside, but in particular between the plug contacts, which lie on different polarity.
  • the plug-in sequence ie the order in which the electrode arrangement and the respective plug-in contact are inserted, is arbitrary, which greatly simplifies handling.
  • the respective contact points and contact surface existing contact points need not necessarily be sealed in all application traps against liquid, for example when working in a guaranteed dry environment.
  • at least one of the contact points encapsulated and sealed against liquid which is particularly advantageous in urological operations in which fluid exposures occur frequently. In this case, the sealing of one of the contact points is already sufficient, in particular to avoid an electrically conductive liquid film between the two contact points.
  • the first plug contact having contact pad sealed, so the contact point with indirect contacting. It can be the design principles of DE 202005013853 Ul apply.
  • the two connectors of the cable can be moved independently of each other, and then leave z.
  • the two connectors are formed with a parallel plug-in direction. This significantly facilitates the operation and also the construction.
  • the plug can hereby be rigidly connected.
