Title

(EN) SURGICAL PUNCTURING AND ACCESS DEVICE FOR SEMI-RIGID OR SOFT LAYERS OF MATERIAL

(ES) DISPOSITIVO DE PERFORACIÓN Y ACCESO QUIRÚRGICO PARA CAPAS DE MATERIAL SEMI-RÍGIDAS O BLANDAS

(FR) DISPOSITIF DE PERFORATION ET D'ACCÈS CHIRURGICAL POUR COUCHES DE MATÉRIAU SEMI-RIGIDES OU SOUPLES

Abstract

(EN) The invention relates to a surgical puncturing and access device (1000) for layers of semi-rigid or soft material, which allows a cannula to be placed by inserting a trocar, for the transfer of liquid or gaseous fluids in intracorporeal cavities or in lumens (300). The device comprises: an insertion unit (100) for inserting a trocar-cannula assembly (1), formed by an essentially cylindrical external tubular piece (2) that contains a puncturing unit (50) and a drive unit (60) in an interior channel (30) thereof, the proximal part of the external cylindrical tubular piece (2) being connected, during operation, to a base unit (200) by means of a quick connection, the trocar-cannula assembly (1) being disposed inside a guide channel (33) in the puncturing unit (50); and a base unit (200) formed by a flexible base piece (7) with a thin adhesive sheet (8) that attaches same to the contact surface.

(ES) Dispositivo de perforación y acceso (1000) quirúrgico para capas de material semi-rígida o blanda, que permite la colocación de una cánula mediante el disparo de un trócar para la transferencia de fluidos líquidos o gaseosos en cavidades intra-corpó reas o en lúmenes (300), que comprende: una unidad de disparo (100) de un trócar-cánula (1) formada de una pieza tubular externa (2) esencialmente cilíndrica en cuyo canal interior (30) contiene a una unidad de perforación (50) y una unidad de impulsión (60), la pieza externa tubular cilíndrica (2) cuando está en operación, en su parte proximal se une mediante una unión rápida a una unidad basal (200): unidad de perforación (50) donde dicho trócar-cánula (1) dispuestos dentro de dicho canal guía (33); y la unidad basal (200), está conformada por una pieza base flexible (7) con una lámina delgada adhesiva (8) que la fija en la superficie que hace contacto.

(FR) L'invention concerne un dispositif de perforation et d'accès (1000) chirurgical pour des couches de matériau semi-rigides ou souples, qui permet de placer une canule par insertion d'un trocart pour le transfert de fluides liquides ou gazeux dans des cavités intra-corporelles ou dans des lumières (300), qui comprend : une unité d'insertion (100) d'un trocart-canule (1) formée par d'une pièce tubulaire externe (2) essentiellement cylindrique dont le canal intérieur (30) contient une unité de perforation (50) et une unité d'impulsion (60); en fonctionnement, la pièce tubulaire externe cylindrique (2) étant raccordée par liaison rapide, au niveau de sa partie proximale, à une unité de base (200); l'unité de perforation (50) comprenant ledit trocart-canule (1) disposé à l'intérieur dudit canal guide (33); et l'unité de base (200) étant formée par une pièce de base flexible (7) comprenant une fine feuille adhésive (8) qui la fixe à la surface de contact.
