Title
(EN) LOW FRICTION TROCAR VALVE
(FR) VALVE DE TROCART À FAIBLE FROTTEMENT
Abstract
(EN)
Certain aspects of the present disclosure provide a low friction trocar valve (100) comprising a set of sheets (120) arranged circularly and defining an entry point (125) for the insertion of an instrument. In certain aspects, each sheet (120) of the trocar valve's set of sheets (120) comprises areas (122) that overlap with two adjacent sheets (120). The trocar valve is formed in an opening of a valve housing coupled to or formed as part of a trocar cannula to provide a sealing mechanism for preventing the escape of pressurized fluids from the trocar cannula.

Certains aspects de la présente invention concernent une valve de trocart (100) à faible frottement comprenant un ensemble de feuilles (120) disposées de manière circulaire et délimitant un point d'entrée (125) pour l'insertion d'un instrument. Dans certains aspects, chaque feuille (120) de l'ensemble de feuilles (120) de la valve de trocart comprend des zones (122) qui se chevauchent avec deux feuilles adjacentes (120). La valve de trocart est formée dans une ouverture d'un logement de valve accouplé ou formé en tant que partie d'une canule de trocart pour fournir un mécanisme d'étanchéité permettant d'empêcher l'échappement de fluides sous pression à partir de la canule de trocart.
