Abstract

L'invention concerne un couvercle d'accessoire de pointe de stylo de cautérisation, comprenant un élément cylindrique qui peut recevoir un stylo de cautérisation à une première extrémité, la pointe du stylo de cautérisation pouvant s'étendre depuis une deuxième extrémité opposée lorsque le couvercle est dans une configuration rétractée. L'élément cylindrique comporte une exposition latérale ouverte qui permet la sensation du stylo de cautérisation à travers celle-ci. Une ouverture d'exposition de couvercle dans l'élément cylindrique permet d'accéder à un déclencheur du stylo de cautérisation lorsque le couvercle de pointe de stylo de cautérisation est dans la configuration rétractée. Un élément élastique pousse le couvercle de pointe du stylo de cautérisation vers la configuration non rétractée dans laquelle l'accès au déclencheur du stylo de cautérisation n'est pas possible. L'élément cylindrique est facilement rétracté par un anneau de doigt configuré de façon permanente dans l'élément cylindrique, permettant une rétraction aisée du couvercle par l'opérateur en pressant le couvercle vers un accessoire de système de stabilisation de barre de résistance configuré sur le stylo de cautérisation.
