Abstract
A surgical instrument of scissors configuration having one or more suction and spraying openings disposed at the functional end thereof, the openings communicating with a fluid conduit which is carried by and movable with one or both of the instrument handles or manipulating means. Movable conduit extensions selectively locate the suction and spraying openings in areas adjacent the scissors functional ends.
Claims10
A surgical instrument of scissors type configuration, comprising:
- a. first and second elongated members of essentially the same length, each having a manipulating end and a functional end, said functional ends having opposed impermeable inner faces and distal outer faces, said inner faces being substantially adjacent each other in the closed position, the first and second elongated members being pivotally connected at an intermediate point and arranged so that the functional ends together provide a surgical function upon relative movement of said manipulating ends;
- b. first and second fluid conduit means respectively associated with the first and second elongated members, each of said conduit means terminating in an opening in the distal outer face of the associated elongated member at the extreme functional end thereof;
- c. said first fluid conduit means being adapted for connection to a source of negative fluid pressure;
- d. and the second fluid conduit means being adapted for connection to a source of positive fluid pressure.
