Constellation® Vision System PROBES AND HANDPIECES Different probes and handpieces are required for each operating mode of the Constellation® Vision System. Following is a representative selection of probes and handpieces with a general description of each. See the Accessories and Parts section of this manual, or consult your Alcon representative, for a complete selection of all probes, handpieces, and handpiece tips available.
Constellation® Vision System Fragmentation Handpiece The Fragmentation handpiece is configured to provide simultaneous vacuum and fragmentation, or vacuum only, depending upon the console setup. The handpiece has a stainless steel shell for improved reliability and durability. Other than attaching and removing the needle and aspiration line, no assembly or disassembly is required.
Constellation® Vision System WARNINGS! Use of an ultrasonic handpiece other than the U/S, or use of a handpiece repaired without Alcon authorization, is not permitted, and may result in patient injury, including potential shock hazard to patient and/or operator. Use of the U/S handpiece in the absence of irrigation flow and/or in the presence of reduced or lost aspiration flow can cause excessive heating and potential damage to the cornea and other tissues. 2.
Constellation® Vision System TurboSonics® Family of Tips U/S tips are made of medical grade titanium alloy, and are attached to an U/S handpiece to deliver mechanical energy to the lens, assisting in its removal by aspiration. Depending on the needs and technique preferred by the surgeon, various styles of tips and tip bevels are available (see Figure 2-77). Various U/S tip styles are color coded. • • • 1.1 mm U/S Tips - The standard ultrasonic tips are the original 1.1 mm TurboSonics® tips.
Constellation® Vision System MicroSmooth™* Infusion Sleeves Infusion sleeves cover the tip of the handpiece to provide irrigation to the anterior chamber of the eye during surgery (see Figure 2-78). Infusion sleeves are used with the Infiniti™* U/S handpiece, and with some Ultraflow™* I/A handpieces. Infusion sleeves used with Infiniti™* U/S handpieces require a BSI (bubble suppression insert). Infusion sleeves must be correctly matched to the specific tip type (see the following descriptions).
Constellation® Vision System Ultraflow™* Handpieces and Tips The Ultraflow™* handpiece is used in I/A mode to maintain chamber pressure with irrigation while removing cortical material via aspiration. (See Figure 2-79 and note the band markings on the tips that identify size of tip aperture.) Some configurations of the Ultraflow™* IT and SP handpieces also use infusion sleeves.
