Abstract
Abstract A medical forceps jaw assembly for obtaining biopsy specimens or grasping objects. The forceps has a jaw assembly which incorporates a clevis pivot. The clevis pivot has a cross hole which is parallel to the center line of the jaw assembly. This cross hole, along with the lumens of the clevis and the shaft comprise a passageway. A diagnostic or procedural member can be passed through this passageway. By incorporating the diagnostic or procedural member into the passageway of the medical forceps, the need for two separate devices is eliminated for procedures which require both. By locating the cross hole appropriately in the clevis pivot, the diagnostic or procedural member can be centered between the two jaws. When used with an endoscope, the device allows two functions to be simultaneously accomplished using an endoscope with only one working channel. The design of the device is simple and cost effective.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
162 words
A medical forceps jaw assembly comprising: a clevis having a pivot; pin a first jaw pivotally attached to said clevis by said clevis pivot pin, said first jaw having a limited rotation around said clevis pivot pin; a second jaw which opposes said first jaw; an opening through said clevis pivot pin said opening allows passage substantially along the center line of said jaw assembly; a drive member which is used to actuate at least one of said jaws, said drive member is capable of movement between a first proximal position and a second distal position which effects opening or closing between said jaws; an elongated member for diagnostic or procedural purposes with a center line substantially parallel to the center line of said jaw assembly, said elongated member passes through said opening in said clevis pivot pin whereby incorporation of said elongated member into said jaw assembly allows an additional diagnostic or procedural function to be performed by said medical forceps.
Claim 2
Dependent Claim
162 words
A medical forceps jaw assembly comprising: a clevis having a pivot; pin a first jaw pivotally attached to said clevis by said clevis pivot pin, said first jaw having a limited rotation around said clevis pivot pin; a second jaw which opposes said first jaw; an opening through said clevis pivot pin said opening allows passage substantially along the center line of said jaw assembly; a drive member which is used to actuate at least one of said jaws, said drive member is capable of movement between a first proximal position and a second distal position which effects opening or closing between said jaws; an elongated member for diagnostic or procedural purposes with a center line substantially parallel to the center line of said jaw assembly, said elongated member passes through said opening in said clevis pivot pin whereby incorporation of said elongated member into said jaw assembly allows an additional diagnostic or procedural function to be performed by said medical forceps.
