Abstract
Abstract A method and surgical apparatus to provide incision and anastomosing guidance through viscera positioned in side-by-side relation. The apparatus, applicable to either open or closed methods of anastomosis, includes two pairs of longitudinally extending and horizontally engageable members. The paired members are in vertically displaced contact and engage the viscera on opposing surfaces whereupon the thin walled membranes are forced into an undulating path forming folds in a longitudinal path. The apparatus provides passages through which a double layer of sutures may be passed repeatedly intersecting opposing visceral folds. A guide path is formed in a longitudinal direction between the contacting paired members to permit a longitudinal incision through the viscera. Positioning of the apparatus in a fixed relation throughout the operation is accomplished by fixed and adjustable clamps fastened to opposing ends of the paired members.

Claim 7
Dependent Claim
42 words
The apparatus as recited in claim 1 wherein said incision guidance means includes said first and second pairs of members having respective longitudinally directed recesses formed on respective interfacing vertically contacting surfaces and extending through said respective members in said horizontal direction.
Claim 8
Dependent Claim
43 words
The apparatus as recited in claim 1 wherein said suturing guidance means includes said plurality of teeth in said first and second pair of members having horizontally and vertically aligned grooves extending longitudinally through said teeth when said pairs of members are engaged.
Claim 9
Dependent Claim
62 words
The apparatus as recited in claim 1 wherein said alignment means comprises a pin element rigidly secured to one of said elongated longitudinal members extending in a vertical direction substantially facing said opposing pair of longitudinal members one member of which having an opening to allow slideable insertion of said pin to permit vertical alignment between said first and second paired members.
Claim 10
Dependent Claim
59 words
The apparatus as recited in claim 1 wherein said clamping means comprises an adjustable clamp secured to a first end of one of said elongated longitudinal members of one of said pairs of members and rotatable with respect thereto to contact said opposing interfacing longitudinal member with a predetermined force in said horizontal direction when said members are engaged.
Claim 11
Dependent Claim
70 words
The apparatus as recited in claim 9 wherein said adjustable clamp comprises: a frame member pivotally secured to said first end of one of said elongated longitudinal members and rotatable from a first position about said first end to an opposing position on said interfacing member; and, a threaded screw member passing through said frame member in said horizontal direction and manually adjustable to contact said interfacing elongated longitudinal member.
Claim 12
