Abstract
Abstract A surgical instrument has a hollow elongated shaft for insertion into the body, the shaft having a longitudinal axis and supporting a pair of interacting pivotable jaws on its distal end and being connected at its proximal end to a first movable component of an operating handle, with a reciprocable rod located within the shaft. The rod is connected to a second movable component of the handle for reciprocation within the shaft when the first and second components are moved relative to each other. The jaws are pivotally connected by a pivot pin supported on the shaft transversely to the axis. Each of the jaws has a proximal end extending proximally from the pivot pin. Each of the proximal ends is provided with an elongated opening therethrough, each the openings forming an elongated slot oriented at an oblique angle relative to the longitudinal axis of the shaft. The reciprocable rod has a distal end extending into each slot whereby reciprocation of the rod causes the jaws to open and close.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
231 words
A surgical instrument comprising: a hollow elongated shaft for insertion into the body, said shaft having a distal end supporting a tip component, said shaft being connected at its proximal end to a first movable component of an operating handle, said distal tip component having a longitudinal axis and a bifurcated distal end supporting a pair of interacting pivotable jaws, said distal tip component also having a pair of slots on its lateral edges, said jaws being pivotally connected by a pivot pin supported transversely to the axis of said tip component each of said jaws having a proximal end extending proximally from said pivot pin, each of said proximal ends being provided with an elongated opening therethrough, each of said openings forming an elongated slot oriented at an oblique angle relative to said longitudinal axis, and a reciprocal rod being located within said shaft, a proximal end of said rod being connected to a second movable component of said handle for reciprocation within said shaft when said first and second components are moved relative to each other, said reciprocal rod having a distal end bent in a hook configuration having a section thereof oriented transversely to the longitudinal axis of said rod, said section extending into each of said elongated slots and the elongated openings of said jaws, whereby reciprocation of said rod causes said jaws to open and close.
Claim 2
Dependent Claim
231 words
A surgical instrument comprising: a hollow elongated shaft for insertion into the body, said shaft having a distal end supporting a tip component, said shaft being connected at its proximal end to a first movable component of an operating handle, said distal tip component having a longitudinal axis and a bifurcated distal end supporting a pair of interacting pivotable jaws, said distal tip component also having a pair of slots on its lateral edges, said jaws being pivotally connected by a pivot pin supported transversely to the axis of said tip component each of said jaws having a proximal end extending proximally from said pivot pin, each of said proximal ends being provided with an elongated opening therethrough, each of said openings forming an elongated slot oriented at an oblique angle relative to said longitudinal axis, and a reciprocal rod being located within said shaft, a proximal end of said rod being connected to a second movable component of said handle for reciprocation within said shaft when said first and second components are moved relative to each other, said reciprocal rod having a distal end bent in a hook configuration having a section thereof oriented transversely to the longitudinal axis of said rod, said section extending into each of said elongated slots and the elongated openings of said jaws, whereby reciprocation of said rod causes said jaws to open and close.
Claim 3
Dependent Claim
12 words
An instrument according to claim 1 wherein said jaws comprise scissors blades.
Claim 4
Dependent Claim
25 words
An instrument according to claim 1 wherein said reciprocal rod is of one piece and extends through the entire length of said hollow elongated shaft.
Claim 5
Dependent Claim
35 words
