Patent

CA 2461847

A flexible clip applier includes a ratchet mechanism adapted to locate a clip pusher to a known location after deployment of a distalmost clip. In addition, the clip applier includes a flexible housing into which a train of clips maybe chambered. The flexible housing is constrained from elongation when subject to tensile forces . In accord with another aspect of the invention, the jaw assembly is adapted to have relatively high mechanical leverage which facilitates tissue compression prior to application of a clip.

Applicateur d'agrafes souples comprenant un mécanisme à rochet adapté pour placer un poussoir d'agrafe à un emplacement connu après le déploiement de l'agrafe la plus éloignée. De plus, l'applicateur d'agrafes comporte un boîtier souple dans lequel un train d'agrafes peut être introduit. Le boîtier souple est empêcher de s'allonger lorsqu'il subit des forces de traction. Conformément à un autre aspect de l'invention, la mâchoire est adaptée pour avoir un effet de levier mécanique relativement élevé, ce qui facilite la compression des tissus avant d'appliquer une agrafe.
