Abstract

A hand applicator for laser surgery, wherein a laser fibre (10) is positioned coaxially in a tubular handle (11) and cooled by liquid or gas (11a, 12). The handle has a tube (18) forming a guide made of a soft metal which can be bent by hand into the particular shape required for the application in question. <IMAGE>

Description

SPECIFICATION Laser Surgery Instrument This invention relates to a hand applicatorfor laser surgery, with which a laser fibre is positioned coaxially in a tubular handle casing and cooled by a liquid.
Applicators of this kind are known in various forms. The appliances used hitherto have a focusing lens serving to provide a freely selectable irradiation distance and thus have to be of large dimensions.
The average minimum diameter amounts to 12 mm with the minimum length being about 12 cm. The guide tubes for the laser fibre measure 3-4 mm in diameter and are made in different shapes according to the position in which they are to be applied. This means that the guide tube has to be removed and replaced a number of times in each operation. Apart from the undesirable interruption in the continuity of application, this tube changing process increases the time taken up by the operation and involves extra expenditure on a selection of curved tubes having to be kept in readiness on the instrument stand.
An object of this invention is to provide a hand applicator which will overcome the time-consuming and complicated task of changing the tubes in the course of an operation and make it unnecessary to have a number of versions of the tube available.
According to this invention there is provided a hand applicator for laser surgery in which a laser fibre is positioned coaxially in a tubular handle casing and liquid or gas cooled, wherein the fibre extends through an elongate tubular housing made of a soft metal alloy which can be shaped and re-shaped by hand to adapt same according to requirements of the medical application.
An embodiment by way of example is described hereinafter with reference to the accompanying drawing.
As shown in the drawing, this shows an embodiment constructed from assemblies with a handle casing 11 with a liquid or gas feed 12 for a cooling device lia and coupling elements 13a, 13b for the flexible transmission cable which shrouds and supports the laser light guide fibre 10. An elongated tubular housing 17, 18 is provided with a connecting coupling for handle 11. The housing 17, 18 is made up of a flexible tube 18 with a rounded end protector attachment 18a and a quadrangular connecting piece 17. The latter is provided on two side surfaces with flats 1 7a, enabling it to be mounted and with a connector 16 to engage the coupling element 15 of the handle 11. The connector and coupling element 15,16 may be constructed as a bayonet lock, spring detent lock or plug clamp lock. As these form part of the prior art a description thereof is not given.
The flexible tube 18 may be made of a soft brass alloy, although the use of other alloys is possible.
The important requirement is that the tube should be capable of being bent by hand without difficulty and without fracturing and also be restorable to the original shape at any time. Other metal alloys of lead or tin are naturally likewise conceivable, subject to the aforementioned requirements of easy non-destructive bendability.

Claims (7)

1. A hand applicator for laser surgery in which a laser fibre is positioned coaxially in a tubular handle casing and liquid or gas cooled, wherein the fibre extends through an elongate tubular housing made of a soft metal alloy which can be shaped and re-shaped by hand to adapt same according to requirements of the medical application.
2. A hand applicator in accordance with Claim 1, wherein the tubular housing comprises a flexible tube with a rounded end protector attachment and a quadrangular connector with a coupling connector.
3. A hand applicator in accordance with Claim 1 or 2, wherein the handle, the liquid or gas-feed and the tubular housing are interconnected by coupling means.
4. A hand applicator in accordance with Claim 2 or 3 wherein the coupling means or coupling connector comprise a bayonet lock device.
5. A hand applicator in accordance with any one of Claims 2 to 4, wherein the coupling means or coupling connector are constructed in the form of a spring detent lock or a plug clamp lock.
6. A hand applicator in accordance with any one of Claims 2 to 5, wherein the flexible tube is made of a soft brass alloy.
7. A hand applicator constructed and arranged to function as described herein with reference to the accompanying drawings.
