Title
(EN) ACTIVE CROSSING DEVICE WITH BENDABLE TIP
(FR) DISPOSITIF DE CROISEMENT ACTIF AVEC POINTE PLIABLE
Abstract
(EN)
A device (10) includes a shaft (12) and an impactor tip (28) that protrudes distally from a distal section (20) of the shaft (12). The impactor tip (28) is coupled to an inner sliding tube (32) which slides in an outer tube (34). A distal spring (38) is located between a proximal end of the impactor tip (28) and a portion of the outer tube (34). The distal spring (38) is pre-loaded by the impactor tip (28). A pulling wire (40) is coupled to the inner sliding tube (32) for pulling the inner sliding tube (32) together with the impactor tip (28) proximally against the distal spring (38).
(FR)
L'invention concerne un dispositif (10) comprenant un arbre (12) et une pointe d'impacteur (28) qui fait saillie de manière distale à partir d'une section distale (20) de l'arbre (12). La pointe d'impacteur (28) est couplée à un tube coulissant interne (32) qui coulisse dans un tube externe (34). Un ressort distal (38) est situé entre une extrémité proximale de la pointe d'impacteur (28) et une partie du tube externe (34). Le ressort distal (38) est préchargé par la pointe d'impacteur (28). Un fil de traction (40) est couplé au tube coulissant interne (32) pour tirer le tube coulissant interne (32) conjointement avec la pointe d'impacteur (28) de manière proximale contre le ressort distal (38).
