摘要： An ophthalmic injection device has a dispensing chamber housing, a plunger, a shaft connected to the plunger, and a pneumatic cylinder. The dispensing chamber housing has an inner surface partially defining a dispensing chamber for holding a quantity of a substance. The plunger is engaged with the inner surface of the dispensing chamber housing, is capable of sliding in the dispensing chamber housing, and is fluidly sealed to the inner surface of the dispensing chamber housing. The pneumatic cylinder has a piston movable in a chamber. The piston is connected to a shaft. The shaft is connected to the plunger. The shaft has teeth located on its surface. A pawl is engageable with the teeth and limits movement of the shaft to a dispensing direction. Pneumatic pressure introduced into the chamber moves the piston, shaft, and plunger in a dispensing direction.

摘要： A vitrectomy probe having a variable duty cycle cutting mechanism is disclosed. The probe includes a motor and a cam driver rotationally driven by the motor. The cam driver has a non-planar driver surface having surface features that vary at different radii. A follower mechanism is arranged to selectively interface with the driver surface at different radii on the driver surface in a manner to selectively interface with the varied surface features at the different radii.

摘要： A system and method for identifying a component for use with a surgical device are disclosed. A component of a surgical device includes an identifier, such as a RFID tag. Data from the RFID tag is transmitted to a RFID reader operably coupled to the device. A controller identifies the component based on the received data and determines whether the component can be used with the surgical device based on criteria, such as whether the received data is an authorized code that matches data stored in memory or whether the received data solves or satisfies an algorithm. The authorized codes are selected from a larger set of available codes. The controller can enable or disable the operation of the device with the component based on whether the criteria is satisfied and can cause the surgical device to be configured for use with the component.
