Abstract

A surgical instrument (1) utilizing a laser beam is frequently used to obtain an incision (15) through gasification or vaporisation. This gasification and vaporisation is usually extremely injurious to the person operating the instrument (1). The object of the present invention is to draw off as much of said vaporisation and gasification as possible. In practise this is achieved by providing the radiation end (3) of the instrument (1) with a conical sleeve (7) connected to a suction arrangement (11-13) so that the beam is surrounded from the centre and outwards by a suction effect.

Description

504 438 10 15 20 25 30 2 bajonettspår, som samverkar med nämnda anslutning. 504 438 10 15 20 25 30 2 bayonet grooves, which cooperate with said connection.

Den fria änden till nämnda hylsa kan givas ett avstånd utåt från instruments strålande, så att garanterat all gasbildning och ångbildning försvinner genom nämnda hylsa.The free end of said sleeve can be given a distance outwards from the radiating of the instrument, so that guaranteed all gas formation and steam formation disappears through said sleeve.

Det kan vara lämpligt att förse nämnda hylsa vid sin främre ände med distanser- gan till instrumentets strålande, så att korrekt sugöppning bildas.It may be appropriate to provide said sleeve at its front end with the spacer to the instrument radiating, so that the correct suction opening is formed.

Föreliggande uppfinning kommer närmare att beskrivas i samband med bifogade tre ritningar, där Fig. 1 visar ett kirurgiskt instrument utnyttjande laserstràle, där Fig. 2 visar separat den hylsa, som instrumentet enligt Figur 1 är försedd med och där Fig. 3 visar en komplett anläggning för att utföra kirurgiska ingrepp med hjälp av ett instrument utnyttjande laserstråle.The present invention will be described in more detail in connection with the accompanying three drawings, in which Fig. 1 shows a surgical instrument using a laser beam, in which Fig. 2 shows separately the sleeve with which the instrument according to Fig. 1 is provided and in which Fig. 3 shows a complete plant to perform surgical procedures using an instrument using a laser beam.

I figurema är 1 ett kirurgiskt instrument avsett för att utnyttja en laserstråle. lnstrumentet är medelst en del 2 ansluten till en strålgenerator. lnstrumentet har en strålande 3 och stråländen är ansluten till en gasslang 4 med hjälp av en nippel 5. Gasen föres in i den kanal, som utgör passage för laserstràlen. Strålän- den 3 omges av en hylsa 7, som vid sin bakre ände har ett bajonettspår 10 avsett att samverka med nippeln 5. I sin främre ände är hylsan 7 försedd med distansor- gan, så att det runt instrumentets strålände bildas en sugkanal. Änden till hylsan kan vara så placerad, att den befinner sig en bit framför stråländens 3 fria ände, som är försedd med ett spröt 6, avsett att reglera kirurginstrumentet avstånd till den vävnad 14, som skall förses med ett snitt 15. Hylsan har en anslutning 9 för en slang 11, som i sin tur är ansluten till ett filter 12. Efter filtret är slangen ansluten till luftsugenhet 13.In fi gurema, 1 is a surgical instrument intended to utilize a laser beam. The instrument is connected to a beam generator by means of a part 2. The instrument has a radiating 3 and the jet end is connected to a gas hose 4 by means of a nipple 5. The gas is introduced into the channel which forms the passage for the laser beam. The beam end 3 is surrounded by a sleeve 7, which at its rear end has a bayonet groove 10 intended to cooperate with the nipple 5. At its front end, the sleeve 7 is provided with the spacer, so that a suction channel is formed around the beam end of the instrument. The end of the sleeve may be located so that it is located a bit in front of the free end of the beam end 3, which is provided with a rod 6, intended to regulate the distance of the surgical instrument to the tissue 14 to be provided with an incision 15. The sleeve has a connection 9 for a hose 11, which in turn is connected to a filter 12. After the filter, the hose is connected to an air suction unit 13.

Hylsan 7 kan vara tillverkad av vilket lämpligt material som helst och kan utnyttjas 10 504 438 3 som en engángsartikel, men kan också utgöras av plast eller metall. Använda material kan vara så valda, att en autoklavrengöring är möjlig.The sleeve 7 can be made of any suitable material and can be used as a disposable article, but can also be made of plastic or metal. Materials used can be so selected that an autoclave cleaning is possible.

Före en operation påsättes hylsan 7 kirurginstrumentets strålände 3, varvid nippeln 5 föres in i bajonettspàret 10. Därmed sitter hylsan definitivt rejält fast vid själva instrumentet. Hylsan anslutes sedan till en slang 11, som står i förbindelse med ett filter 12 och en sugenhet 13. Vid ingrepp utsättes instrumentet för en rejäl sugverkan, som sker inifrån strålens centrum och utåt. Härvid är hylsans avstånd till stràländens 3 fria ände så vald, att maximal utsugning från snittet 15 erhålles.Prior to an operation, the sleeve 7 is attached to the beam end 3 of the surgical instrument, whereby the nipple 5 is inserted into the bayonet groove 10. Thus, the sleeve is firmly firmly attached to the instrument itself. The sleeve is then connected to a hose 11, which is connected to a filter 12 and a suction unit 13. When engaged, the instrument is subjected to a substantial suction action, which takes place from inside the center of the jet and outwards. In this case, the distance of the sleeve to the free end of the beam end 3 is chosen so that maximum extraction from the cut 15 is obtained.

Filtret 12 utnyttjas för att samla upp skadliga partiklar och förbränna dessa.The filter 12 is used to collect harmful particles and incinerate them.
