  • Publication number: 20020049461
    Abstract: A vitreous surgical apparatus in which an inner tubular blade is moved in an axis direction with respect to an outer tubular blade by supply and exhaust of compressed air to excise a part of a vitreous body in an eyeball and aspirate and discharge the excised part out of the eyeball, the apparatus including: a plurality of solenoid valves each of which is opened and closed for performing the supply and exhaust of the compressed air; and a control unit which synchronously drives the solenoid valves to open and close in order to move the inner tubular blade at a desired cutting speed.

  • Publication number: 20020002368
    Abstract: A medical system capable of giving different treatments in a row to a patient comprises a first treatment apparatus, a second treatment apparatus, an operation unit, a memory, a communication unit and a selection switch. The first treatment apparatus has a first treatment unit for a first treatment and a first control part which sends a control signal to the first treatment unit based on a first setting signal for the first treatment. The second treatment apparatus has a second treatment unit for a second treatment different from the first treatment and a second control part which sends a control signal to the second treatment unit based on a second setting signal for the second treatment. The operation unit has an indication part and an operation part, and is capable of inputting the first and second setting signals at different times, and the two signals are then transmitted to the first and second control parts respectively by the communication unit.
