Abstract

Claims (25)

1. A surgical device, comprising:

a first member extending from a proximal end to a distal end and having a first surface opposite a second surface;

a first channel defined by a first channel wall descending into said first surface and extending in-between said distal end and proximal end of said first member;

a second channel defined by a second channel wall descending into said first surface running in-between said distal end and said proximal end, said second channel formed adjacent said first channel;

a first side edge at said proximal end communicating between said first surface and said second surface;

a first aperture communicating through said first side edge with said first channel, said aperture sized to accommodate translation of a cabled imaging component therethrough;

at least one viewing aperture communicating through said first channel wall and through said second surface for providing a view of tissue surrounding said surgical device to said cabled imaging component;

said second channel communicating through said side edge;

whereby with said surgical device upon an insertion into the body of a patient through an incision to an as-used positioning, said cabled imaging component is translatable through said first aperture into said first channel for communicating images of areas surrounding said surgical device therefrom, and a blade for cutting chosen said tissue is insertable along said second channel forming a guided translational pathway for said blade;

a second member extending from a proximal end to a distal end and having a first surface opposite a second surface;

a first channel defined by a first channel wall descending into said first surface of said second member, and extending in-between said distal end and proximal end of said second member;

a second channel defined by a second channel wall descending into said first surface of said second member and extending in-between said distal end and said proximal end of said second member, said second channel formed in said second member formed adjacent said first channel thereof;

a second side edge at said proximal end of said second member communication between said first surface and said second surface thereof;

a second aperture communicating through said second side edge to said first channel of said second member, said second aperture sized to accommodate translation of said cabled imaging component therethrough;

said second channel formed in said second member communicating through said second side edge;

a disengageable cooperating connector engaging said first member and second member to form an assembled instrument, with respective first sides of each of said first member and said second member facing each other across a gap therebetween, said gap extending through opposing distal ends of said first and second members;

said first channel of said first member in position directly across said gap from said first channel of said second member defining a first tunnel of said assembled instrument;

said second channel of said second member in position directly across said gap from said second channel of said first member defining a second tunnel of said assembled instrument;

said second tunnel communicating through said second side edge and forming an opening for translation of said blade to said second tunnel;

said second aperture and said first aperture both providing individual separate pathways for said cabled imaging component to said first tunnel; and

said gag positionable around said chosen tissue to be severed by said blade, whereby only said chosen tissue within said gap is severable and tissue surrounding said second tunnel with said surgical device in said as-used positioning is protected from such severing.

2. The surgical device of claim 1 additionally comprising:

said second surface at said distal end having a curved portion, said curve extending from a position on said second surface adjacent said distal end, to said distal end, said curve providing a path through said incision for reducing a force required for said insertion.

3. The surgical device of claim 1 additionally comprising:

a stop positioned in said second channel, said stop preventing translation of said blade past said distal end of said first member.
