Patent

CA 2271029

Systems, methods, and miniature instruments (e.g., 12, 30, 40, 50, and 102) are disclosed for minimally invasive surgical procedures. A miniature surgical instrument can be inserted directly into a body cavity (16) through a cannula (10, 118) in a way that a surgeon can insert his or her hand into the cavity (16) through a separate minimal incision and use the miniature instruments. A miniature surgical system can include: a cannula (10, 118) having a hollow body configured to receive a miniature surgical instrument (102) and a tether (13, 104) connected to the instrument; and a plunger (108) sized to engage a proximal end of the body and including a conduit (106) therethrough for receiving the tether. The system can also include the tether and the instrument. During use, the instruments can be quickly and safely removed from the body cavity to enable the surgeon to use his or her fingers, e.g.,to manipulate tissue.

Systèmes, méthodes et instruments miniatures (tels que 12, 30, 40, 50 et 102) utilisés pour des actes chirurgicaux minimalement invasif. On peut introduire directement dans une cavité corporelle (16) un instrument chirurgical miniature à travers une canule (10, 118) de manière à ce qu'un chirurgien puisse introduire sa main dans la cavité (16) par une incision minimale séparée et utiliser les instruments miniatures. Un système chirurgical miniature peut comprendre: une canule (10, 118) constituée d'un corps creux configuré pour recevoir un instrument chirurgical miniature (102) et un fil d'attache (13, 104) reliés à l'instrument; et un piston (108) dimensionné pour se trouver en contact avec l'extrémité proximale du corps et comportant un conduit (106) qui le traverse, destiné à recevoir le fil d'attache. Le système peut également comprendre le fil d'attache et l'instrument. Pendant l'utilisation, les instruments peuvent être sortis de la cavité corporelle rapidement et sans risque pour permettre au chirurgien d'utiliser ses doigts, pour manipuler des tissus, par exemple.
