Flexible microsurgical instruments incorporating a sheath having tactile and visual position indicators are disclosed. A flexible lubricous sheath (115, 215, 315) which covers at least a distal portion of the flexible coil of the instrument is provided with either contrasting colored stripes (252, 352) or palpable ridges, or both, which are located a predetermined distance from a distal end of the instrument. When the coil is removed from an endoscope, the practitioner or the assistant observes the coil as it is withdrawn and notices the appearance of the stripes as an indication that the distal end of the instrument is not far away. Upon observing the stripes, the practitioner or the assistant may then slowly remove the remainder of the coil to avoid whipping the distal end as it exits the endoscope. Alternatively, the practitioner or assistant may grasp the coil between a thumb and fingers to feel for the palpable ridges as the coil is withdrawn from the endoscope or feel for vibration of the coil as the textured portion exits the endoscope.
Cette invention concerne des instruments flexibles de microchirurgie qui comportent un fourreau possédant des indicateurs de position visuels et tactiles. Un fourreau flexible et glissant (115, 215, 315) recouvre la partie distale au moins de la bobine flexible de l'instrument. Ce fourreau comporte des bandes colorées de contraste (252, 352) ou des arêtes palpables, ou encore les deux, qui sont situées à une distance prédéterminée de l'extrémité distale de l'instrument. Lorsque l'on retire la bobine d'un endoscope, le praticien ou son assistant peuvent observer cette dernière au fur et à mesure de son retrait, et noter l'apparition des bandes qui indiquent que l'extrémité distale de l'instrument se rapproche. En observant les bandes, le praticien ou son assistant peuvent retirer lentement le reste de la bobine et éviter tout fouettement de l'extrémité distale lorsqu'elle sort de l'endoscope. Dans un autre mode de réalisation, le praticien ou son assistant peuvent saisir la bobine entre le pouce et un autre doigt de manière à sentir les arêtes palpables lorsque l'on retire la bobine de l'endoscope, ou de manière à sentir les vibrations de ladite bobine lorsque sa partie texturée sort de l'endoscope.
