<p>The surgical tool for laser based endocanaliculary dacriocistorinostomy enables a step by step advancing of the optical fibre which conducts the laser light from the laser light source to the place of the surgical intervention in the direction towards the place of the surgical intervention, in the case when during the intervention due to the high energy of the laser light at the outlet a certain part of the optical fibre blows which reaches beyond the canula of the appliance. The doctor initiates the shift without interrupting the performance of the intervention by pushing the control button using one hand only. In this case the shifting mechanism is activated. This mechanism is designed in such a way that it moves the optical fibre 10 forward by a preset step of always equal length. The shifting mechanism also ensures that the optical fibre can not move backwards towards the canula. The surgical appliance at the same time ensures irrigation.</p> |
