    摘要： An ophthalmic surgical system 10 detects a change in a viscosity of a material being aspirated from an eye 32. The system 10 includes a control module 18 connected to an aspiration pump 20, and a flow meter 19 connected to the control module 18 and the aspiration pump 20. The flow meter 19 provides a flow rate of material aspirated from the eye 32 by the aspiration pump 20. A surgical handpiece 24 connected to the aspiration pump 20 and the control module 18 is inserted into the eye 32 during surgery. The control module 18, during surgery, detects a step change in the flow rate of material aspirated from the eye 32 and the control module 18 further causes the surgical system 10 to alert a surgeon that a change in viscosity of the material being aspirated has been detected indicating that the handpiece 24 has moved from a material of a first viscosity to a material of a second viscosity.

    摘要： A liquid level sensing and monitoring system for a medical fluid infusion system has an IV spike with a pressure sensor which contacts fluid in an infusion container such as an IV bag or bottle. When an adequate amount of fluid is in the container, the resulting pressure on the sensor is at a relatively high level; however, when the fluid reservoir is nearly depleted, the pressure on the sensor falls to a low level, thereby activating the sensor and associated control circuitry which operates an alarm or warning indicator. In lieu of the pressure sensor, the device may use a resistive or capacitive sensor. When the liquid level falls below the electrical sensor, its state changes, and the alarm circuitry is activated.

    摘要： A surgical instrument includes a handle having a pair of actuating wings and a removable instrument tip. The instrument tip is constructed to perform a surgical operation. The handle includes an axially movable slider actuated by the actuating wings which operate the instrument tip. A shaft extends through the handle and is coupled to the instrument tip so that rotation of the shaft rotates the tip without interfering with the axial movement of the slider. The gripping surface of the actuating wings have a rounded surface to allow limited rotational movement of the instrument in the user's hand. The gripping surfaces are inclined toward the instrument tip to resist the handle slipping from the user's hand during use in the near vertical orientation.

    摘要： A multi-function pick-manipulator device that provides the functions of a vitreoretinal pick, fiberoptic illumination, and irrigation/aspiration. The manipulator may also function as a bipolar diathermy device. To provide a compact, multi-function device, the aspiration tube projects distally beyond the distal end of the fiber optic containing support tube of the manipulator. The projecting aspiration tube is bent and shaped at its tip to define a pick-like structure that extends in a direction generally transverse to the axis of the fiber optics. An aspiration opening is defined through the wall of the aspiration tube proximal to the pick-like tip.
