Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
131 words
An endoscopic instrument comprising: an endoscopic distal head portion for carrying out a step in an endoscopic surgical procedure, said step in an endoscopic procedure including tissue manipulation, stapling, ligation, cutting or the combination of such steps; a shaft connected to and extending proximally from said head portion, means for applying a motion to said shaft, means disposed in said head portion for translating the motion applied to the shaft into a force and/or motion of the head portion to carry out the step in the procedure, p1 sensing means for measuring motion of a predetermined part of said head portion, said sensing means disposed in said head portion; and control means for controlling of the force and/or motion of the head portion said control means interconnected with said sensing means.
Claim 2
Dependent Claim
131 words
An endoscopic instrument comprising: an endoscopic distal head portion for carrying out a step in an endoscopic surgical procedure, said step in an endoscopic procedure including tissue manipulation, stapling, ligation, cutting or the combination of such steps; a shaft connected to and extending proximally from said head portion, means for applying a motion to said shaft, means disposed in said head portion for translating the motion applied to the shaft into a force and/or motion of the head portion to carry out the step in the procedure, p1 sensing means for measuring motion of a predetermined part of said head portion, said sensing means disposed in said head portion; and control means for controlling of the force and/or motion of the head portion said control means interconnected with said sensing means.
Claim 3
Dependent Claim
19 words
An instrument according to claim 1 wherein the means for applying motion to the shaft is a D.C. motor.
Claim 4
Dependent Claim
16 words
An instrument according to claim 2 wherein the D.C. motor is releasably connected to the instrument.
Claim 5
Dependent Claim
132 words
An endoscopic instrument comprising: an endoscopic distal head portion for carrying out a step in an endoscopic surgical procedure, a shaft connected to and extending proximally from said head portion, means for applying a motion to said shaft, means disposed in said head portion for translating the motion applied to the shaft into a force and/or motion of the head portion to carry out the step in the procedure, sensing means for measuring motion of a predetermined part of said head portion, said sensing means disposed in said head portion; control means for controlling of the force and/or motion of the head portion said control means interconnected with said sensing means; and wherein the instrument is a clip applier for applying a multiplicity of ligating clips to vessels to close the vessels.
Claim 6
Dependent Claim
132 words
An endoscopic instrument comprising: an endoscopic distal head portion for carrying out a step in an endoscopic surgical procedure, a shaft connected to and extending proximally from said head portion, means for applying a motion to said shaft, means disposed in said head portion for translating the motion applied to the shaft into a force and/or motion of the head portion to carry out the step in the procedure, sensing means for measuring motion of a predetermined part of said head portion, said sensing means disposed in said head portion; control means for controlling of the force and/or motion of the head portion said control means interconnected with said sensing means; and wherein the instrument is a clip applier for applying a multiplicity of ligating clips to vessels to close the vessels.
Claim 7
Dependent Claim
43 words
An instrument according to claim 4 wherein the head portion comprises a pair of opposing jaws for holding a ligating clip and the motion measured by the sensing means disposed in said head portion comprises detecting when the jaws are open or closed.
Claim 8
Dependent Claim
51 words
An instrument according to claim 4 wherein the head portion comprises a plurality of ligating clips and pair of opposing jaws for holding a ligating clip and the motion measured by the sensing means disposed in said head portion comprises detecting whether or not a clip has moved between said jaws.
