ABSTRACT:
A powered handpiece for use in endophthalmic surgery comprises a projecting tubular surgical instrument including an inner tubular member slidably received within a coaxial outer tubular member for reciprocation therein, a pneumatic actuator for imparting reciprocation to the inner tubular member, and a coupling member interposed between the actuator and the surgical instrument for transmitting reciprocating motion from the actuator to the inner tubular member. The coupling member has a recessed configuration permitting a flexible suction or infusion tube to be connected to the proximal end of the inner tubular member. The pneumatic actuator, coupling member, and proximal portion of the tubular surgical instrument are received in tandem arrangement by a housing having a side opening for the flexible suction or infusion tube and a separable anterior section for permitting interchangeability among different surgical instruments.
