This invention is a trocar (10) having a working channel extending along an axis (11) between a distal end and a proximal end that includes a cannula (14) at the distal end and a housing (12) at the proximal end defining a working channel of the trocar. A valve (32) disposed in the working channel separates the trocar (10) into regions proximal (45) of the valve (32) and regions distal (43) of the valve (32). The valve includes elastomeric means (50, 101) forming a first seal that is openly closable across the working channel. A wall (56) of the valve (32) extends radially outwardly of the elastomeric means (50, 101) and forms a second seal with the housing (12). The trocar also includes means (216) for defining a passage extending from regions exterior of the trocar through the regions proximal of the valve (32) and into the regions distal of the valve (32). Valve means (154) disposed across this passage controls the administration of fluid through the passage and into the working channel of the cannula.

L'invention a pour objet un trocart (10) pourvu d'un canal de travail qui s'étend le long d'un axe (11) entre une extrémité distale et une extrémité proximale et comporte une canule (14) à l'extrémité distale et un logement (12) à l'extrémité proximale, lesquels définissent un canal de travail du trocart. Une valve (32) disposée dans le canal de travail sépare le trocart (10) en zones proximales (45) de la valve (32) et zones distales (43) de la valve (32). La valve comprend des moyens élastomères (50, 101) qui forment un premier joint d'étanchéité fermé dans le canal de travail et qui peut être ouvert. Une paroi (56) de la valve (32) s'étend dans le sens radial vers l'extérieur à partir des moyens élastomères (50, 101) et forme un second joint d'étanchéité avec le logement (12). Le trocart comporte également des moyens (216) définissant un passage entre les régions extérieures du trocart et les régions distales de la valve (32), en passant par les régions proximales de la valve (32). Un moyen formant valve (154) disposé en travers du passage régule l'administration de liquide par le passage vers le canal de travail de la canule.
