Title
(EN) TIP DETECTION APPARATUS AND METHOD FOR MEDICAL DEVICE
(FR) APPAREIL ET PROCÉDÉ DE DÉTECTION DE POINTE POUR DISPOSITIF MÉDICAL
Abstract
(EN)
An apparatus and method of detecting an interchangeable tip of a handpiece of an ocular surgical system is disclosed. The interchangeable tip of the system includes an irrigation port that receives fluid flowing from an irrigation source and an aspiration port that removes or aspirates fluid and/or materials from the surgical field, in particular a patient's eye, through use of an aspiration source or pump. The method comprises attaching the interchangeable tip to the handpiece, introducing fluid flow into the system and determining the fluid flow rate of fluid flow in the system, determining the pressure of fluid flowing into the interchangeable tip, determining the pressure of fluid flowing out of the interchangeable tip and comparing the flow rate and pressure information to known flow rate and pressure readings of known types of interchangeable tips to determine the type of interchangeable tip being used.

La présente invention concerne un appareil et un procédé de détection d'une pointe interchangeable d'une pièce à main d'un système chirurgical oculaire. La pointe interchangeable du système comprend un orifice d'irrigation qui reçoit le liquide s'écoulant depuis une source d'irrigation et un orifice d'aspiration qui extrait ou aspire du liquide et/ou des matériaux du champ chirurgical, en particulier de l’œil d'un patient, par l'utilisation d'une source d'aspiration ou d'une pompe. Le procédé comporte la fixation de la pointe interchangeable à la pièce à main, l'introduction d'un écoulement de liquide dans le système et la détermination du débit de liquide de l'écoulement de liquide dans le système, la détermination de la pression du liquide s'écoulant dans la pointe interchangeable, la détermination de la pression du liquide s'écoulant en sortie de la pointe interchangeable et la comparaison des informations de débit et de pression à des lectures de débit et de pression connues de types connus de pointes interchangeables afin de déterminer le type de pointe interchangeable étant utilisée.
