Title
(EN) SOFT TISSUE CUTTING INSTRUMENT WITH SELF LOCKING, MULTI-POSITION, AND SLIDE BUTTON LINEARLY ACTUATED RETRACTABLE BLADE OR HOOK
(FR) INSTRUMENT DE COUPE DE TISSU MOU AVEC AUTO-VERROUILLAGE, MULTI-POSITION ET BOUTON OU CROCHET RÉTRACTABLE À ACTIONNEMENT LINÉAIRE À BOUTON COULISSANT
Abstract
(EN)
A system and method for cutting soft tissue with a retractable surgical cutting device (10). The device (10) includes a handle (12), an actuator (18) positioned thereon, and a sheath (14) attached thereto, where the sheath (14) surrounds a shaft (4) with a blade (16) attached to the distal end thereof. The device (10) also includes a drive and locking mechanism (100) connected to the actuator (18) and to the shaft (4) within the internal space of the handle (12), wherein the drive and locking mechanism (100) is configured to move the shaft (4) in the first direction and lock the shaft (4) in the shaft first position in response to movement of the actuator (18) in one of the first direction or the second direction, and wherein the drive mechanism (100) is configured to move the shaft (4) in the second direction and lock the shaft (4) in the shaft second position in response to movement of the actuator (18) in the other one of the first direction or the second direction.
(FR)
L'invention concerne un système et un procédé de coupe de tissus mous à l'aide d'un dispositif de coupe rétractable (10). Le dispositif (10) comprend une poignée (12), un actionneur (18) positionné sur celle-ci et une gaine (14) fixée à celle-ci, la gaine (14) entourant un arbre (4) avec une lame (16) fixée à son extrémité distale. Le dispositif (10) comprend également un mécanisme d'entraînement et de verrouillage (100) relié à l'actionneur (18) et à l'arbre (4) à l'intérieur de l'espace interne de la poignée (12), le mécanisme d'entraînement et de verrouillage (100) étant conçu pour déplacer l'arbre (4) dans la première direction et verrouiller l'arbre (4) dans la première position d'arbre en réponse au mouvement de l'actionneur (18) dans l'une de la première direction ou de la seconde direction, et le mécanisme d'entraînement (100) étant configuré pour déplacer l'arbre (4) dans la seconde direction et verrouiller l'arbre (4) dans la seconde position d'arbre en réponse au mouvement de l'actionneur (18) dans l'autre parmi la première direction ou la seconde direction.
