Abstract
Abstract A multifunctional endoscopic scissors instrument for use in performing endoscopic procedures within an anatomical cavity includes a handle and an elongate tubular member having a proximal end coupled with the handle for being disposed externally of the anatomical cavity and a distal end for being disposed within the anatomical cavity and carrying a pair of opposed, relatively movable blades. The blades are operable by manipulation of the handle to cut tissue and other objects such as, for example, lengths of suture material. In addition, the elongate tubular member defines a channel permitting fluids and other instruments to be communicated at the operative site without the need of having to remove the endoscopic scissors instrument from the body.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
96 words
A multifunctional endoscopic scissors instrument for use in performing endoscopic procedures within an anatomical cavity comprising a handle; an elongate tubular member having a proximal end coupled with said handle for being disposed externally of the anatomical cavity and a distal end for being disposed within the anatomical cavity and carrying a pair of opposed, relatively movable blades, said elongate tubular member defining a channel permitting access to an operative site within the anatomical cavity from outside the body; said blades being movable relative to one another by manipulation of said handle to perform cutting operations.
Claim 2
Dependent Claim
96 words
A multifunctional endoscopic scissors instrument for use in performing endoscopic procedures within an anatomical cavity comprising a handle; an elongate tubular member having a proximal end coupled with said handle for being disposed externally of the anatomical cavity and a distal end for being disposed within the anatomical cavity and carrying a pair of opposed, relatively movable blades, said elongate tubular member defining a channel permitting access to an operative site within the anatomical cavity from outside the body; said blades being movable relative to one another by manipulation of said handle to perform cutting operations.
Claim 3
Dependent Claim
87 words
A multifunctional endoscopic scissors instrument for use in performing endoscopic procedures within an anatomical cavity as recited in claim 1 wherein said blades are biased apart toward an open position and further comprising an outer tubular member disposed telescopically around said elongate tubular member and having a proximal end coupled with said handle and a distal end movable relative to said elongate tubular member by manipulation of said handle between a retracted position allowing said blades to open and an extended position causing said blades to close.
