Description

PATENTKRAV 1. Endoskopisk sprøjteindretning med et væsketilførselsrør (2) forbundet med den bageste ende af en spiralformet rende (12) forseglet på både de indre og ydre overflader, idet en væske sendt gennem væsketilførselsrøret (2) til den spiralformede rende (12) og udsendt fra dens forreste ende hvirvles omkring den langsgående akse gennem centret af den spiralformede rende (12) inden i et væskehvirvelkammer (20) udformet foran den spiralformede rende (12), således at den udsprøjtes fra et udløb (17) dannet i centrum af den forreste endeflade af væskehvirvelkammeret (20) , kendetegnet ved, at væskehvirvelkammeret (20) er udformet som et hulrum afgrænset af en cirkulær kegleoverflade, som er konveks i retning mod udløbet (17) . 2. Endoskopisk sprøjteindretning ifølge krav l, kendetegnet ved, at udløbet (17) er placeret i forlængelse af rummet afgrænset af den cirkulære kegleoverflade indenfor en del af væskehvirvelkammeret (20) som omfatter den langsgående akse gennem centrum af den spiralformede rende (12). 3. Endoskopisk sprøjteindretning ifølge krav 1, kendetegnet ved, at et fremspring (24) ind i centrum af udløbet (17) er udformet til at stikke frem fra væskehvirvelkammeret (20). 4. Endoskopisk sprøjteindretning ifølge krav 2, kendetegnet ved, at et fremspring (24) ind i centrum af udløbet (17) er udformet til at stikke frem fra væskehvirvelkammeret (20) . 5. Endoskopiske sprøjteindretning omfattende: et væsketilførselsrør (2); en dyseelementdel (11); en distal endeafdækning (16), som huser dyseelement-delen (11) deri og støtter dyseelementdelen (11) til væsketilførselsrøret (2), idet den distale endeafdækning (2) har en udløb (17), hvor dyseelementdelen (11) og den distale endeafdækning (16) kooperativt afgrænser et væskekammer forbundet med udløbet (17), og mindst en spiralformet rende (12), som forbinder et indre af væsketilførselsrøret (2) med væskekammeret, kendetegnet ved, at væskekammeret er afgrænset af en konisk overflade af den distale endeafdækning (16) og en konisk overflade af dyseelementdelen (11) overfor den koniske overflade af den distale endeafdækning (16).Patent claim 1. Endoscopic syringe device with a liquid supply tube (2) connected to the rear end of a helical groove (12) sealed on both the inner and outer surfaces, a liquid sent through the liquid supply tube (2) to the helical groove (12) and emitted from its front end, swirl around the longitudinal axis through the center of the helical channel (12) within a fluid vortex chamber (20) formed in front of the helical channel (12) so as to be ejected from an outlet (17) formed in the center of the forward end surface of the fluid vortex chamber (20), characterized in that the fluid vortex chamber (20) is formed as a cavity defined by a circular cone surface which is convex towards the outlet (17). Endoscopic syringe device according to claim 1, characterized in that the outlet (17) is located in extension of the space defined by the circular cone surface within a portion of the fluid vortex chamber (20) comprising the longitudinal axis through the center of the helical channel (12). Endoscopic syringe device according to claim 1, characterized in that a projection (24) into the center of the outlet (17) is designed to project from the fluid vortex chamber (20). Endoscopic syringe device according to claim 2, characterized in that a projection (24) into the center of the outlet (17) is designed to project from the fluid vortex chamber (20). An endoscopic syringe device comprising: a fluid supply tube (2); a nozzle element portion (11); a distal end cap (16) housing the nozzle member portion (11) therein and supporting the nozzle member portion (11) of the fluid supply tube (2), the distal end cap (2) having an outlet (17), wherein the nozzle member portion (11) and the distal end cap (16) cooperatively delimiting a fluid chamber connected to the outlet (17), and at least one helical channel (12) connecting an interior of the fluid supply tube (2) to the fluid chamber, characterized in that the fluid chamber is delimited by a conical surface of the distal end cap (16) and a tapered surface of the nozzle member (11) opposite the tapered surface of the distal end cap (16).
