AT400666B - Suction tube holder for a laser handpiece for extracting smoke in a fashion synchronous with movement - Google Patents

Abstract

Special suction tube holder for attachment to a (CO2-) laser handpiece 13 for the purpose of more efficient smoke extraction. A spacer (distance piece) 2 which can be angled off and includes a suction tube guide 6 at the distal end is fitted on a laser handpiece 13 via a ring piece 1 (of varying size, depending on the handpiece). The suction tube end therefore exactly follows each movement of the handpiece 13, and thus the location of the development of smoke. The therapist (operator) is not impaired in gripping the handpiece 13 by the fact that the spacer 2 is held at one point (and a bent suction tube 8 is used). The spacer can be angled away by means of an articulated joint (articulation) 17 with a stop part 18, and the angle can be finely regulated with the aid of a screw 3, and a spring 5 maintains the position set. The suction tube 8 can be displaced along the suction tube axis in the suction tube guide 6 of the spacer 2. As a result, the suction tube 8 can be brought up laterally as closely as possible to the smoke seat 11 of the smoke at an appropriate angle, that is to say it is possible for the smoke 10 to be extracted as efficiently as possible in a way adapted to the treatment situation which does not impede the laser beam 12, the flow of rinsing gas 14 or the therapist. <IMAGE>

Claims (3)

AT 400 666 B Various skin changes (e.g. genital warts or cancer (pre-stages) on the outer genitals) can be treated excellently today with a C0-2 laser beam. During treatment, however, the vaporization (evaporation) effect on the tissue creates a significant smoke development. This smoke represents an unpleasant smell and a visual impairment, 5 moreover it is assumed to have at least potentially harmful effects on health (especially virus particles, irritants) (Ref. 1,2,3). For the protection of patient, practitioner and staff, effective smoke extraction and smoke filtering must therefore be ensured. In laser therapy with a so-called &quot; handpiece &quot; (most common form of laser beam application) static or manual suction devices have been used so far, but they do not always guarantee optimal smoke extraction and often require additional assistance. An additional device for such a handpiece is now intended on the one hand to ensure optimal and safe smoke evacuation in every treatment situation, to follow every movement of the practitioner and to save on assistant personnel. The practitioner himself should not be hindered by this facility; full sterility must also be provided. 15 The additional device consists of a special suction tube holder (Fig. 1 and 2) attached to the handpiece (13). A bendable spacer (2) of approximately 5 cm is fixed to the handpiece (13) via a ring piece (1). The swivel angle (4) (fine) can be regulated by a screw device (3), a stop part (18) and a corresponding joint (17) and there is a stop. A spring (5) maintains the set position (or the bend (4)), but it can also be changed briefly at any time by hand using pressure 20 and then springs back into the set position against the stop of the screw (3 ) on the stop part (18) of the joint. At the distal end of the spacer (2) there is a suction tube guide (6) into which a commercially available sterilized suction tube (8), which is (usually) bent at the end, is inserted and fixed with a screw (7). The distance from the end of the intake manifold to the fabric ("laser hearth" / smoke development) (11) can also be adjusted in this guide by pushing forward or backward. Overall, this additional device can be used to bring the end of the intake manifold at a variable optimal distance from the laser hearth (in at least 2 levels) and the smoke (10) is immediately eliminated from the side of the laser beam path (12). In addition, the end of the suction pipe follows every movement of the handpiece and thus the location of the smoke. The distance between the handpiece (13) and the handler (13) is not affected by the spacer (and the use of a bent suction tube (8)). The additional device is largely made of metal and can therefore be steam sterilized in the usual way. In connection with the sterile suction tube (8) complete sterility is given. This device can also be attached to handpieces from different manufacturers. The smoke cannot be extracted by the handpiece itself, as this would interfere with the flushing gas flow (14) and laser beam (12) coming from the handpiece (flushing gas mainly prevents the penetration of smoke particles into the handpiece (13) and contamination of the lens (15) ). In addition, the suction effect of recirculated-air smoke extractors has recently been impaired by the prescription 40 of several filter devices or has weakened the effectiveness of existing suction devices (in particular of so-called &quot; bells &quot; or suction pipes with a larger cross-section). On the one hand, this suggests a reduced intake manifold diameter (with increased suction speed), on the other hand, an improved coordination / synchronization of smoke generation and extraction. Both are achieved by the described device. 45 claims 1. intake manifold holder (Fig. 1, 2) for a laser handpiece (13) for motion-synchronized smoke extraction, characterized by an adapted to the handpiece diameter ring piece (1), a spacer (2) and a suction pipe guide (6). 2. intake manifold holder according to claim 1, characterized in that the spacer (2) by means of a joint (17) in the plane handpiece - intake manifold is bendable. 3. intake manifold holder according to claim 2, characterized in that by means of a spring attached to the joint (5) in the intake manifold guide (6) attached suction pipe (8) from the handpiece (13) is spread apart and that this spreading by an adjustable stop (3, 18) is limited. 2 AT 400 666 B intake manifold holder according to claim 1, characterized in that the intake manifold (8) in the intake manifold guide (6) is displaceable along the intake manifold axis.
