Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
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.
Claim 2
Dependent Claim
160 words
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.
Claim 3
Dependent Claim
56 words
The surgical instrument defined by claim 1, wherein each conduit means defines a passageway formed within at least a portion of its associated elongated member, and further comprising a fluid connector member affixed to each elongated member and communicating with the associated passageway, said connector members being adapted for connection to the sources of fluid pressure.
Claim 4
Dependent Claim
31 words
The surgical instrument defined by claim 1, wherein the functional ends of the first and second elongated members comprise clamping members constructed and arranged to perform a forceps-type or clamping function.
Claim 5
Dependent Claim
26 words
The surgical instrument defined by claim 1, wherein the functional ends of the elongated members comprise gripping portions constructed and arranged to perform a needle-holding function.
Claim 6
Dependent Claim
31 words
The surgical instrument defined by claim 1, wherein the point at which the first and second elongated members are pivotally connected is disposed nearer said functional ends than said manipulating ends.
Claim 7
Dependent Claim
41 words
The surgical instrument defined by claim 1, further comprising vacuum control means associated with said first fluid conduit means for controlling the amount of negative fluid pressure differential across the opening in said first fluid conduit means at said functional end.
Claim 8
Dependent Claim
85 words
The surgical instrument defined by claim 6, wherein said vacuum control means comprise: a. a slot-like opening formed in the first elongated member and communicating with said first fluid conduit means; and b. a slide member movably mounted over said slot-like opening for partially covering said slot-like opening to control the amount of negative fluid pressure conveyed to the opening in said first conduit means at said functional end of the first elongated member, said slide member movable in response to urging by finger force.
Claim 9
Dependent Claim
49 words
The surgical instrument defined by claim 1 and further comprising pressure control means associated with said second fluid conduit means for regulating the transmission of positive fluid pressure from its source to the opening in said second fluid conduit means at the functional end of said second elongated member.
Claim 10
Dependent Claim
25 words
The surgical instrument defined by claim 8 wherein said pressure control means are attached to said second elongated member and are operable by finger force.
Claim 11
Dependent Claim
149 words
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 inner faces and 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. fluid conduit means associated with at least one of the first and second elongated members, the conduit means terminating in at least one fluid opening disposed on the inner face of the first elongated member, and at least one fluid opening disposed on the outer face of the first elongated member; c. the fluid conduit means being adapted for connection with a source of fluid pressure.
Claim 12
Dependent Claim
149 words
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 inner faces and 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. fluid conduit means associated with at least one of the first and second elongated members, the conduit means terminating in at least one fluid opening disposed on the inner face of the first elongated member, and at least one fluid opening disposed on the outer face of the first elongated member; c. the fluid conduit means being adapted for connection with a source of fluid pressure.
