Patent

CA 2485487

A wound closure material applicator (10) is provided which includes a handle assembly (12) having a movable handle, a body portion (14) extending distally from the handle assembly and a tip assembly (16) supported adjacent the distal end of the body portion. The tip assembly includes a housing (78) defining a bore, a tip member and a seal member (84). The tip assembly housing defines an inlet channel (88) and a valve seat (82a) positioned adjacent the outlet of the inlet channel. The seal member is movable distally within the housing bore from a closed position in which the valve member (82) abuts the valve seat (82a) to an open position in which the valve member is spaced from the valve seat. The tip assembly is configured such that movement of the seal member from the open to the closed position causes a reduction of pressure within a discharge channel of the tip assembly to minimize drippage of wound closure material form the applicator.

L'invention concerne un applicateur (10) destiné à une matière de fermeture de plaie. Cet applicateur comprend un ensemble de préhension (12) pourvu d'une poignée mobile, une partie corps (14) s'étendant distalement à partir de l'ensemble de préhension et un ensemble embout (16) porté adjacent à l'extrémité distale de la partie corps. L'ensemble embout comprend un boîtier (78) définissant un trou, un élément embout et un élément joint (84). Le boîtier de l'ensemble embout définit un canal d'entrée (88) et un siège de valve (82a) adjacent à la sortie du canal d'entrée. L'élément joint est distalement mobile dans l'orifice du boîtier d'une position fermée, dans laquelle l'élément valve (82) est contigu au siège de valve (82a), à une position ouverte, dans laquelle l'élément valve est distant du siège de valve. L'ensemble embout est configuré de telle manière que le mouvement de l'élément joint de la position ouverte à la position fermée entraîne une réduction de la pression qui règne dans un canal de décharge de l'ensemble embout pour réduire au minimum la fuite goutte à goutte de la matière de fermeture de plaie de l'applicateur.
