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

S U R G I C A L I N S T R U M E N T
The present invention relates to a surgical instrument utilizing a laser beam for performing an operation such as an incision or the removal of undesired parts. Both incisions and removal are effected by vaporisation or gasification of the part of the body concerned. This vaporisation or gasification gives rise to cloud around the site of the operation and it is extremely dangerous for an operator to breathe in the vapour and gas generated. It is therefore desirable in one way or another to arrange a suction device to remove the gas from the operation area. Certain success has also been achieved but not complete success and it is therefore highly desirable to maximally remove said gasification and vaporisation, particularly for the sake of the operator since it has been found that said vaporisation and gasification can give rise to cancer.
The object of the present invention is to achieve maximal removed of said gases and vaporisation, with known instruments, so that the operation area is free from gas and other particles and thus easy to see. From the purely practical point of view this is achieved by providing the end from whence the laser beam is emitted, with a sleeve that surrounds said end in such a way that a space exists between the inner wall of the sleeve and said end of the instrument. The inner end of the sleeve is hermetically sealed to the instrument and its front end is completely open, its orifice being at or forward of the end emitting the laser beam. Said sleeve is then connected to a suction unit. Thus, when the suction unit is in operation, all gas and vaporisation around the laser beam will be withdrawn via the arrangement formed by said sleeve and said suction unit. The suction capacity will be arranged from the centre of the laser beam and radially outwards.
Known surgical instruments utilizing a laser beam have a nipple for connection of the gas to be supplied to the laser beam. Such a connection is suitable to function as part of a bayonet catch for said sleeve since the sleeve has a bayonet notch cooperating with said connection. The free end of said sleeve may be spaced from the beam end of the instrument, thus guaranteeing that all gas and vapour produced will disappear through said sleeve.
It may be advisable to provide said sleeve at its forward end with spacers to the beam end of the instrument so that a correct suction opening is formed.
The present invention will be described in more detail with reference to the accompany drawings, in which
Figure 1 shows a surgical instrument utilizing a laser beam, Figure 2 shows separately the sleeve with which the instrument according to Figure 1 is provided, and Figure 3 shows a complete unit for performing a surgical operation with the aid of an instrument utilizing a laser beam.
In the figures 1 denotes a surgical instrument designed to utilize a laser beam. The instrument is connected by a part 2 to a laser beam generator. The instrument has a beam end 3 which is connected to a gas hose 4 by means of a nipple 5. The gas is introduced into the channel constituting the passage for the laser beam. The beam end 3 is surrounded by a sleeve 7, provided at its rear end with a bayonet notch 10 designed to cooperate with the nipple 5. At its front end the sleeve 7 is provided with spacers so that a suction channel is formed around the beam end of the instrument. The end of the sleeve may be situated slightly forward of the free end of the beam end 3, this free end being provided with a feeler 6 intended to regulate the distance of the surgical instrument from the tissue 14 in which an incision is to be made. 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 a suction unit 13.
The sleeve 7 may be made of any suitable material whatsoever and can be used as a disposable article, or it may be made of plastic or metal. The material may be selected to enable sterilisation in an autoclave. Prior to the operation the sleeve 7 is fitted onto the beam end 3 of the surgical instrument and the nipple 5 is inserted into the bayonet notch 10. The sleeve is thus firmly secured to the instrument itself. The sleeve is then connected to a hose 11 communicating with a filter 12 and suction unit 13. During surgery the instrument is subjected to a strong suction action from inside the centre of the beam and outwards. The distance of the sleeve to the free end of the beam end 3 is chosen so that maximum suction is obtained from the incision 15. The filter 12 is used to collect particles for burning.

Claims

CLAIM
1. A surgical instrument utilizing a laser beam for cutting, wherein the beam cooperates with a gas such as carbon dioxide gas and wherein the instrument is provided at the free end of the front part from whence the laser beam is emitted, with an outwardly directed feeler that determines the distance from the free end to the organic tissue to be operated on, characterized in that the front part (3) of the instrument is surrounded by a sleeve (7) that is hermetically sealed at its rear end and completely open at its forward end at the end of said instrument, whereby said sleeve end may be located between the end of the feeler (6) and the end (1) of the instrument, that said sleeve (7) is connected to a suction device (13), the suction of which is transmitted to the open end of the sleeve (7), thereby subjecting the organic tissue (14) to suction from the point of encounter of the beam and radially outwards from said point.
