Definitions

  • the present invention relates to a device for guiding a medical probe for body cavities with devices for rinsing and suctioning of rinsing liquids and a housing which has connections for the rinsing and suction lines and a guide channel for the probe which can be displaced and locked therein.
  • the invention is concerned with the management of probes, e.g. B. laser, coagulation, argon or adhesive probes and others, with simultaneous rinsing and suction of rinsing liquids through or on the shaft of the probe.
  • probes e.g. B. laser, coagulation, argon or adhesive probes and others
  • simultaneous rinsing and suction of rinsing liquids through or on the shaft of the probe Only the joint use of the probes with rinsing and suction leads to the best possible work results. For example, rinsing largely prevents carbonization during bipolar coagulation.
  • a laser beam can also be guided on a water jet. For this purpose, however, there should be the possibility of being able to control the flushing together with the probe guide on the probe holder itself.
  • a device of the type mentioned at the outset is known from WO 94/05200.
  • the amount of rinsing and suction liquid is regulated outside of the device in a separate pumping device. No regulation is possible directly with the device itself, so that the simultaneous actuation of all functions is relatively cumbersome.
  • the entire contaminated device has to be either cleaned and disinfected after being used once or thrown away as a whole.
  • a pure flushing device for surgical purposes is known from EP 642 800, in which an elastic hose carrying the flushing medium can be disconnected by means of push buttons which cannot be locked.
  • the device cannot easily be combined with the above-mentioned instruments, Active measures are not possible with it and also not intended.
  • the present invention has for its object to provide a device of the type mentioned, with which the quantity control of the suction and rinsing process can be carried out in a simple manner on the device itself.

  • the longitudinal channel 9 is at its distal end to the transfer and suction channel 7 of the angled transition piece 6 opened against the probe receptacle 36 in the form of the contaminated space 38. However, this is sealed against its outwardly open proximal end 53 by the hollow seal 45 arranged between the hollow screw 45 screwed into the distal end of the probe receptacle 36 and the longitudinal channel 9.
  • the probe 43 is inserted into the longitudinal bore 52 of the probe receptacle 36 so as to be longitudinally displaceable from the proximal end with different retention force.
  • the probe 43 is clamped and sealed in the bore 52 in a special way by means of a tensioning device 39 by turning the rotary handle 54 attached to the proximal end of the probe receptacle 36 when it is removed or inserted into the longitudinal channel 9.
  • the clamping device 39 is arranged to prevent contamination of the longitudinal bore 52 at the distal end of the probe receptacle 36 and consists essentially of an annular and elastic insert 41 with a receiving bore 42 which is inserted into the hollow screw 45 around the probe 43.
  • the insert 41 When it rotates relative to the probe receptacle 36 by means of the thread 40, the insert 41 is pressed against the spacer 55 in the probe receptacle 36 and its receiving bore 42 is narrowed or expanded by the probe 43 depending on the direction of rotation. As a result, the probe 43 is either freely displaceable in the bore 52 or non-positively connected to the probe receptacle 36.
  • This narrowing and widening of the receiving bore 42 is possible even when the probe receptacle 36 is fully inserted in that the hollow screw 45 comes to rest on the cross pin 44 and prevents it from rotating, while the probe receptacle 36 is rotated on the rotary handle 54 and axially against the insert part 41 , this narrowing movement creates.

  • the hollow screw 45 is provided with inclined surfaces 49 at its front end, the spring-loaded pin 47 is pushed back into the longitudinal channel 9 when the probe receptacle is inserted before it engages in the groove 48. Due to the presence of a circumferential groove 48, the probe holder 36 can also be rotated about its axis in the installed state, which is important, for example in the case of coagulation probes, for taking the correct position.
  • a pin 50 with grids 51 is mounted in a longitudinally displaceable manner in the upper part 2, to which the pin 47 is fastened and which is moved back and forth together with the slide 46 via pin 47.
  • a resilient pin 22 engages in the catches 51 of the bolt 50 (see FIG. 3), so that the probe receptacle 36 can be positioned in several locking positions, so that a clamped probe 43 can be reproducibly brought into the correct working position.

  • the handle can be used by right-handed and left-handed people thanks to the symmetrical arrangement of the three slides 10, 46. All three slides can be operated with one hand using the handle without having to grip.
  • Each slide 10 acts in the same way on one of the two hoses 4, either on the smaller one with the flushing lumen 23 or on the larger one with the suction lumen 24, by, as in two versions, 1 and 8 measured, rollers 15 via cam 11 and 20 connected to the quantity slides 10 each press a pivot lever 14 pivotable on an axis 13 with a sliding edge 12 against the hoses 4 and thus their cross-section by squeezing together from a full to the narrow completely closed opening.

  • pressure rollers can press the hoses directly against an oblique locking surface and thus change their cross section.

Abstract

L'invention concerne un dispositif pour guider une sonde médicale pour des cavités corporelles, comportant des dispositifs pour rincer et aspirer des liquides de rinçage et un boîtier qui présente des connexions pour des conduites de rinçage et d'aspiration, ainsi qu'un canal de guidage pour la sonde qui peut y être déplacée et fixée. Le dispositif comprend un module supérieur (I), un module inférieur (II) et un module intérieur (III) réunis pour former une poignée, lesdits modules pouvant être dissociés les uns des autres. Le module intérieur (III) comprend deux conduites tubulaires (4) flexibles pour le rinçage et l'aspiration comportant chacune une pièce de raccordement (5) au niveau de l'extrémité proximale et une pièce de jonction (6) coudée, au niveau de l'extrémité distale et se présentant sous forme de pièces jetables. Il est prévu des coulisseaux (10) sur le module supérieur (I) pour réguler le débit dans les conduites tubulaires (4). Le module inférieur (II) comporte un canal oblong (9) qui loge une cavité de réception de la sonde (36), déplaçable dans le sens longitudinal depuis la face proximale et à travers le trou oblong (52) de laquelle la sonde (43) est guidée. Sur le module supérieur (I), il est prévu un autre coulisseau actionnable manuellement, servant à déplacer la cavité de réception de sonde (36). Le canal oblong (9) est ouvert à l'extrémité distale en direction du canal d'aspiration (7) de la pièce de jonction (6) coudée, de manière à créer une étanchéité vis-à-vis de la cavité de réception de la sonde (36).
