Cutting-suctioning instrument having an elongated support and first and second, opposed distal jaws, at least one of which is pivotable about a transverse axis and adapted to be closed by an actuator, and a suction throat defined between proximal portions of the two jaws. Preferably, a sliding inner tube, which defines the suction passage, serves as actuator to move the pivotable jaw. As a cutter for meniscal cartilage, a hollow tube defining a tissue-fragment transport, suction passage is arranged to communicate through the open throat with the region between the jaws to receive cut tissue while suction is associated with the proximal end of the instrument for enabling tissue to be drawn from between the jaws, through the throat and then through the transport passage while the instrument remains in situ for repeated cutting. Preferred embodiments of the instrument are especially useful in arthroscopic surgery. |
