A surgical instrument with a scissors-type handle mechanism is provided, with the handle mechanism being characterized by first and second handle members and a toggle linkage coupled to the handle members adapted to lock the handle members in a closed position.
A surgical instrument comprising: an outer, hollow shaft having a longitudinal axis, a first proximal end, a first distal end and a first length; an inner shaft co-axially disposed in said outer shaft for reciprocal movement with respect to said outer shaft, said inner shaft having a second proximal
A surgical instrument comprising: an outer, hollow shaft having a longitudinal axis, a first proximal end, a first distal end and a first length; an inner shaft co-axially disposed in said outer shaft for reciprocal movement with respect to said outer shaft, said inner shaft having a second proximal end, a second distal end, and a second length, said second length being longer than said first length; means for surgical interaction with animal tissue associated with said first and second distal ends, said surgical interaction means comprising first and second tissue interacting means movable relative to one another transversely of said longitudinal axis between a first open position and a second closed position by axially directed changes in the relative positions of said first and said second distal ends; and a self-locking mechanism for changing the relative positions of said first and said second distal ends lengthwise of said longitudinal axis, said mechanism comprising: (A) driver means mounted on said inner shaft substantially adjacent said second proximal end, said driver means being slidable relative to said inner shaft along the axis of said inner shaft; (B) at least one flexible linkage means having a first linkage end, a second linkage end and a central portion, said first linkage end being connected to said outer shaft at a first point located radially outwardly of and substantially adjacent to said first proximal end of said outer shaft, said second linkage end being connected to said driver means at a second point located radially outwardly of said inner shaft, and said central portion being adapted to receive a force applied substantially normally to said longitudinal axis and transmit said force to said driver means and said outer shaft so as to move said driver means relative to said outer shaft along the axis of said inner shaft, the maximum length of said linkage means being longer than the minimum axial separation between said first point and said second point when said first and second tissue interacting means are in said first open position and also when said first and second tissue interacting means are in said second closed position; and (C) force-transmitting means coupled to said inner shaft and engageable by said driver means for transmitting an axial force from said driver means to said inner shaft in response to a force applied to said central portion normally of said longitudinal axis, whereby a force applied to said central portion in a first direction normal to said longitudinal axis will cause said linkage to move said driver means in a first axial direction and a force applied to said central portion in a second opposite direction normal to said longitudinal axis will cause said linkage to move said driver means in a second opposite axial direction, whereby said first and second tissue interacting means are caused to move from one to the other of said first open position and said second closed position depending on the direction of the normal force applied to said central portion; said linkage being arranged so as that said mechanism is self-locking when said first and second tissue interacting means are in said second closed position.
