Abstract

La présente invention concerne une pince marqueuse et un dispositif de pince pour chirurgie permettant de trouver de façon simple et rapide la position précise du site d'incision lors d'une opération, par l'ajout de la fonctionnalité de marqueur de position au rôle basique d'une pince corporelle par la mise en place d'une substance radioactive dans la pince. La pince marqueuse pour chirurgie de la présente invention peut comprendre : un corps de pince principal auto-extensible ; une partie de marqueur radioactif prévue vers la base du corps de pince principal, comprenant une substance radioactive et dont la fonction consiste à faire écran à la substance radioactive et à la libérer ; et une partie de fixation de la pince qui fixe le corps de pince principal de façon occlusive lorsqu'elle est déplacée de manière coulissante sur le corps principal de la pince au moyen d'une force externe à partir de la position où elle est fixée à la partie du marqueur radioactif.
