Title
(EN) SURGICAL CANNULA WITH CHANNELS FOR IRRIGATION AND SUCTION
(FR) CANULE CHIRURGICALE COMPRENANT DES CANAUX POUR L'IRRIGATION ET L'ASPIRATION
Abstract
(EN)
A cannula body of the surgical cannula has a flange attached to a proximal end. The cannula body is defined by two complementary portions, pivotally connected together proximate the flange. The cannula body has a bore extending from the flange to the surgical site. The cannula is inserted above the surgical site, until a lower surface of the flange contacts the superficial fascia, which acts as a stop to prevent over-insertion. A thread provided on the cannula body holds the cannula in position in the body. Apertures in the flange communicate with channels within the cannula body that extend to the surgical site to provide the surgeon with additional means to provide light, irrigation, and/or suction to and from the surgical site. The two complimentary portions can be pivoted apart from one another to provide an increased amount of access to the surgical site.
(FR)
Selon l'invention, un corps de canule d'une canule chirurgicale comprend une bride fixée à une extrémité proximale. Le corps de canule est défini par deux parties complémentaires, connectées ensemble avec faculté de pivotement à proximité de la bride. Le corps de canule comporte un alésage s'étendant de la bride jusqu'au site chirurgical. La canule est insérée au-dessus du site chirurgical, jusqu'à ce qu'une surface inférieure de la bride entre en contact avec le fascia superficiel, qui agit comme une butée pour empêcher une insertion excessive. Un filetage formé sur le corps de canule maintient la canule en position dans le corps. Des ouvertures dans la bride communiquent avec des canaux à l'intérieur du corps de canule qui s'étendent jusqu'au site chirurgical pour donner au chirurgien des moyens supplémentaires d'apport de lumière, d'irrigation et d'aspiration vers et depuis le site chirurgical. Les deux parties complémentaires peuvent être séparées l'une de l'autre par pivotement afin d'augmenter l'accès au site chirurgical.
