Clip, clamping jaw and assembly for the interruption of the urogenital system

Claim 2

An oviduct clip for long term reversible or permanent interruption of the oviduct and vas deferens in human and animal organisms and for retention in said organisms, to be employed with a combined clip-fitting clamp for fitting the clip on the oviduct and vas deferens in a living organism, comprising: two rigid clamping jaws, one being longer than the other, subStantially parallel inside clamping surfaces forming a longitudinal oviduct clamping slop between the jaws in a closed position of the clip, each part having a first and second end, said second end being a free end; a resilient bridge joining said first ends of said jaws by connecting other portions of the clamping jaws, said bridge forming a transverse slot which communicates and is continuous with the clamping slot, said transverse slot being formed between an inside surface of the resilient bridge and inner first end portions of the clamping jaws; the free second end of said longer clamping jaw having an extending lip, and the free second end of said shorter clamping jaw having a limb, said lip extending around said limb to form a latching mechanism in the closed position of said clip; and said clip being constructed as a single continuous piece of plastic material which is inert to body fluids and body tissues.

Claim 3

An oviduct clip as claimed in claim 1 wherein an inside surface of said lip of said longer clamping jaw and an inside surface of said limb are inclined to the parallel inside jaw surfaces and form an inclined slot which communicates and is continuous with said clamping slot of the closed clip, said inclined slot being not wider than the clamping slot.

Claim 4

An oviduct clip as in claim 1 wherein said inside surface portion of said lip is parallel with an outside surface portion of said limb, said two portions being in mechanical contact with each other during the closed position of said clip.

Claim 5

An oviduct clip as claimed in claim 1 having an overall length of less than 1 cm., a weight between 0.25 and 0.5 grams and a clamping slot having a width approximately of 0.2 mm in the closed position of the clip.

Claim 6

An oviduct clip as claimed in claim 1, wherein said inside clamping surfaces of the clamping jaws have longitudinally raised portions and longitudinally recessed portions, said inside clamping surfaces interfitting with each other in the closed portion of said clip, said inside surfaces being spaced apart by a predetermined uniform distance over the entire inside surfaces of said jaws in the closed position of said lip.

Claim 7

An oviduct clip as claimed in claim 1 in combination with a combined clip-fitting clamp for fitting the clip on the ovirduct and vas deferens in the living human and animal organism, said clip-fitting clamp comprising: a receiving jaw supported by a neck, said receiving jaw having a receiving compartment adapted to receive said clip, said receiving compartment having an open side; a holding jaw for movement toward and away from the open side of said compartment for firmly holding a clip disposed in said compartment, said holding jaw and receiving jaw being movable in a plane of movement; a resilient neck for said holding jaw, said resilient neck for pressing said holding jaw against said receiving jaw when said clip is inserted in said receiving jaw compartment; a closing jaw, said closing jaw for closing an open clip held in said compartment between said receiving and holding jaws, said closing jaw moving perpendicular to the plane of said receiving and holding jaws; an expander affixed to said neck holding said receiving jaw, said expander for moving said holding jaw lengthwise relative to said receiving jaw, wherein said holding jaw may be moved forward or away from said receiving compartment upon lengthwise movement of the expander; and means for controlling said expander for moving said holding jaw.

Claim 8

A combined oviduct clip and clamp as in claim 6, wherein said receiving jaw and holding jaw have needles disposed on inside surfaces of said jaws, an expanding lever for moving the holding jaw against spring force of said resilient neck; said expander having means permitting it to slide on an inside surface of said receiving jaw neck, said means including an elongated aperture and guiding means within said aperture for guiding the expander longitudinally.
