Abstract
Abstract A tool and method for transcystic duct operative cholangiography. A clip having a pair of spring biased jaws has an aperture formed on the jaws. The clip is positioned around the cystic duct and a catheter is extended through the aperture. A needle nose shaped clamp is releasably engageable with the clip and forces the jaws apart to extend around the cystic duct. Release of the clamp allows a spring within the clip to force the jaws together sealing the duct and catheter together.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
150 words
A surgical tool comprising; a clamp having a pair of mutually opposed distal ends and a pair of proximal ends releasably lockable to controllably space apart said distal ends; a tissue clip having a first control end and a second control end lockingly but removably engagable with said distal ends of said clamp, said clip further having a pair of spring biased mutually opposed jaws controllably movable apart by movement of said first control end and said second control end with said jaws being movable from a open position to a closed position, at least one of said jaws including an aperture formed thereon through which a body tube may extend when said jaws are clamped onto tissue; and, a catheter insertable through said aperture when said jaws are clamped onto tissue sealing same to said catheter and allowing fluid flow through said catheter while said clip is positioned thereon.
Claim 2
Dependent Claim
150 words
A surgical tool comprising; a clamp having a pair of mutually opposed distal ends and a pair of proximal ends releasably lockable to controllably space apart said distal ends; a tissue clip having a first control end and a second control end lockingly but removably engagable with said distal ends of said clamp, said clip further having a pair of spring biased mutually opposed jaws controllably movable apart by movement of said first control end and said second control end with said jaws being movable from a open position to a closed position, at least one of said jaws including an aperture formed thereon through which a body tube may extend when said jaws are clamped onto tissue; and, a catheter insertable through said aperture when said jaws are clamped onto tissue sealing same to said catheter and allowing fluid flow through said catheter while said clip is positioned thereon.
Claim 3
Dependent Claim
23 words
The surgical tool of claim 1 wherein: said jaws have mutually facing surfaces with said aperture formed on said surfaces and extending thereacross.
Claim 4
Dependent Claim
24 words
The surgical tool of claim 2 wherein: said jaws are elongated in a first direction with said aperture extending perpendicular to said first direction.
Claim 5
Dependent Claim
154 words
The surgical tool of claim 3 wherein: said clip includes a hollow main body integrally attached to said first control end and to one of said jaws and further includes a rod shaped main body slidably mounted to said hollow main body and attached to said second control end and to the other of said jaws, said clip includes a spring positioned within said hollow main body between said first control end and said rod shaped main body and urging said jaws together but yieldable to allow said jaws to move apart when said first control end is moved toward said second control end as said distal ends of said clamp are moved together; and, said distal ends of said clamps include mutual facing disc shaped surfaces with a plurality of ridges formed thereon to lockingly receive complementary shaped surfaces formed on said first control end and said second control end of said clip.
Claim 6
Dependent Claim
128 words
A surgical tool for use in a transcystic duct operative cholangiogram comprising: a clamp having a pair of mutually opposed distal ends and a pair of proximal ends releasably lockable to controllably space apart said distal ends; a cystic duct clip having a first control end and a second control end lockingly but removably engagable with said distal ends of said clamp, said clip further having a pair of spring biased mutually opposed jaws controllably movable together when said cystic duct is located therebetween by movement of said first control end and said second control end, at least one of said jaws including an aperture formed thereon; and, a cholangiogram catheter extendable through said aperture into said cystic duct when said jaws are clamped onto said cystic duct.
Claim 7
Dependent Claim
128 words
A surgical tool for use in a transcystic duct operative cholangiogram comprising: a clamp having a pair of mutually opposed distal ends and a pair of proximal ends releasably lockable to controllably space apart said distal ends; a cystic duct clip having a first control end and a second control end lockingly but removably engagable with said distal ends of said clamp, said clip further having a pair of spring biased mutually opposed jaws controllably movable together when said cystic duct is located therebetween by movement of said first control end and said second control end, at least one of said jaws including an aperture formed thereon; and, a cholangiogram catheter extendable through said aperture into said cystic duct when said jaws are clamped onto said cystic duct.
Claim 8
Dependent Claim
154 words
The surgical tool of claim 5 wherein: said clip includes a hollow main body integrally attached to said first control end and to one of said jaws and further includes a rod shaped main body slidably mounted to said hollow main body and attached to said second control end and to the other of said jaws, said clip includes a spring positioned within said hollow main body between said first control end and said rod shaped main body and urging said jaws together but yieldable to allow said jaws to move apart when said first control end is moved toward said second control end as said distal ends of said clamps are moved together; and, said distal ends of said clamp include mutual facing disc shaped surfaces with a plurality of ridges formed thereon to lockingly receive complementary shaped surfaces formed on said first control end and said second control end of said clip.
Claim 9
Dependent Claim
25 words
The surgical tool of claim 5 wherein: said clamp has an minimum overall length of at least 26 centimeters to extend out of the wound.
Claim 10
Dependent Claim
109 words
A surgical method of transcystic duct operative cholangiography comprising the steps of: surgically opening the cystic duct; inserting a tube into the surgical opening; providing a clip with mutually facing jaw surfaces at least one of which having an aperture formed thereon; providing a clamp operatively engagable with said clip; removably engaging said clamp with said clip; moving said jaw surfaces apart by moving said clamp; clamping said mutually facing jaw surfaces of said clip onto said cystic duct and around said tube at the surgical opening sealing said duct and said tube together; and, performing a cholangiogram through said aperture and said tube while said clip remains therein.
Claim 11
Dependent Claim
109 words
A surgical method of transcystic duct operative cholangiography comprising the steps of: surgically opening the cystic duct; inserting a tube into the surgical opening; providing a clip with mutually facing jaw surfaces at least one of which having an aperture formed thereon; providing a clamp operatively engagable with said clip; removably engaging said clamp with said clip; moving said jaw surfaces apart by moving said clamp; clamping said mutually facing jaw surfaces of said clip onto said cystic duct and around said tube at the surgical opening sealing said duct and said tube together; and, performing a cholangiogram through said aperture and said tube while said clip remains therein.
Claim 12
Dependent Claim
114 words
A surgical method of transcystic duct operative cholangiography comprising the steps of: surgically removing the gallbladder; inserting a tube into the junction of the cystic duct and the gallbladder; providing a clip with mutually facing jaw surfaces having an aperture formed on said jaw surfaces; providing a clamp operatively engagable with said clip; removably engaging said clamp with said clip; moving said jaw surfaces apart by moving said clamp; clamping said mutually facing jaw surfaces of said clip into said cystic duct and around said tube at the junction sealing said duct and said tube together; removing said clamp; and, performing a cholangiogram through said aperture and said tube while said clip remains therein.
