A retractable surgical blade (10) includes a handle (12) defining a channel (30), and a surgical blade member (14). The surgical blade member includes a body (16) to which is secured a surgical blade (18). The body has a portion which engages the channel so that the surgical blade member can move from a cutting position in which the surgical blade projects from the handle, and can be employed in a surgical procedure to a retracted position in which the surgical blade is disposed in the channel. When in the retracted position, the surgical blade is unable to cut or stab persons associated with the surgical procedures. The device further includes cooperating locking members (60, 53) on the handle and the body to position the surgical blade member in the desired position. An associated method of performing a surgical procedure is also disclosed.

La présente invention concerne une lame (10) rétractable de bistouri chirurgical comportant un manche (12) constitué d'un élément conduit (30) et d'un élément lame chirurgicale (14). L'élément lame chirurgicale comprend une partie centrale (16) à laquelle est fixée ladite lame chirurgicale (18). L'élément central comporte une partie en contact avec le conduit de sorte que l'élément lame chirurgicale puisse se déplacer d'une position de coupe dans laquelle la lame chirurgicale se projette hors du manche où l'on peut l'utiliser pour une opération chirurgicale vers une position rétractée où la lame chirurgicale rentre dans le conduit. Lorsque ladite lame se trouve en position rétractée, elle ne peut ni couper ni blesser les personnes engagées dans l'opération chirurgicale. Le dispositif comporte en outre dans le manche et dans la partie centrale, des moyens de verrouillage (60, 63) de sorte que l'on puisse faire adopter à la lame chirurgicale la position voulue. L'invention concerne aussi une méthode d'exécution de certaines opérations chirurgicales.
