A method of injecting a first viscous fluid into a target tissue simultaneous with aspirating a second viscous fluid from the target tissue is disclosed. A surgical system is provided that is capable of supplying pneumatic pressure and vacuum. A first viscous fluid is injected into the target tissue using pneumatic pressure from the system. A mode of operation of the system is changed to provide vacuum and pneumatic pressure. The second viscous fluid is aspirated from the target tissue using vacuum from the system, and the pneumatic pressure remains substantially constant during aspiration. An improved foot pedal for controlling the simultaneous injection and aspiration of viscous fluids is also disclosed.
Procédé d'injection d'un premier fluide visqueux dans des tissus cibles et d'aspiration simultanée d'un second fluide visqueux desdits tissus cibles. La présente invention concerne également un système chirurgical capable de fournir une pression pneumatique et du vide. Un premier fluide visqueux est injecté dans les tissus cibles à l'aide de la pression pneumatique fournie par le système. Un mode de fonctionnement du système est modifié pour fournir du vide et de la pression pneumatique. Le second fluide visqueux est aspiré des tissus cibles à l'aide du vide fourni par le système, et la pression pneumatique reste pratiquement constante pendant l'aspiration. Une pédale améliorée pour la commande simultanée de l'injection et de l'aspiration de fluides visqueux est également décrite.
