Abstract
Abstract Disclosed is an aneurysm clip pliers for applying an aneurysm clip to a blood vessel. The pliers have a hand grip end and a barrel end. A pusher bar reciprocates within the hollow barrel portion causing the Y-shaped clip grip to open or close, depending upon the position of the push rod. A trigger mechanism causes the spring loaded pusher bar to shift toward the Y-shaped grip when the trigger is squeezed. A locking mechanism enables an aneurysm clip to be placed between the arms of the Y-shaped grip and retained therein until the aneurysm clip is to be applied on the blood vessel. The barrel end is rotatable through 360° with respect to the hand grip end of the aneurysm clip pliers, and the Y-shaped grip permits the aneurysm clip to pivot about an arc slightly larger than 180°. Accordingly, positioning the aneurysm clip on the defective blood vessel is easily accomplished.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
115 words
An aneurysm clip pliers for applying an aneurysm clip to a blood vessel comprising: a hand grip portion; a barrel portion having a first end connected to said hand grip portion and a second end including a Y-shaped grip for holding an aneurysm clip, said Y-shaped grip including two arms, each of said arms being pivotally connected to said barrel portion about its own hinge pin; means connected to each of said arms to bias each of said arms open; and a pusher bar means inserted within said barrel portion, said pusher bar means having a tapered end capable of being positioned between said arms to cause said arms to pivot in a closed position.
Claim 2
Dependent Claim
115 words
An aneurysm clip pliers for applying an aneurysm clip to a blood vessel comprising: a hand grip portion; a barrel portion having a first end connected to said hand grip portion and a second end including a Y-shaped grip for holding an aneurysm clip, said Y-shaped grip including two arms, each of said arms being pivotally connected to said barrel portion about its own hinge pin; means connected to each of said arms to bias each of said arms open; and a pusher bar means inserted within said barrel portion, said pusher bar means having a tapered end capable of being positioned between said arms to cause said arms to pivot in a closed position.
Claim 3
Dependent Claim
184 words
Pliers for applying an aneurysm clip to a blood vessel, comprising: (a) a hand grip portion having a trigger; (b) a barrel portion removably connected at a first end to said hand grip portion, said barrel portion having a second end comprising a Y-shaped grip including: (i) a first arm, having a forward end and an aft end, pivotably connected to said barrel portion about a first hinge pin; (ii) a second arm, having a forward end and an aft end, pivotably connected to said barrel portion about a second hinge pin, whereby said forward ends of said arms cooperate to hold an aneurysm clip; and (iii) means connected to each of said arms and to said barrel portion to bias said arms in an open position to receive an aneurysm clip; and (c) pusher bar means, inserted in said barrel portion, coupled at a first rounded end with said trigger and at a second tapered end with said Y-shaped grip; whereby said trigger is actuated to force said pusher bar means between said aft ends of said arms to close said Y-shaped grip.
Claim 4
Dependent Claim
184 words
Pliers for applying an aneurysm clip to a blood vessel, comprising: (a) a hand grip portion having a trigger; (b) a barrel portion removably connected at a first end to said hand grip portion, said barrel portion having a second end comprising a Y-shaped grip including: (i) a first arm, having a forward end and an aft end, pivotably connected to said barrel portion about a first hinge pin; (ii) a second arm, having a forward end and an aft end, pivotably connected to said barrel portion about a second hinge pin, whereby said forward ends of said arms cooperate to hold an aneurysm clip; and (iii) means connected to each of said arms and to said barrel portion to bias said arms in an open position to receive an aneurysm clip; and (c) pusher bar means, inserted in said barrel portion, coupled at a first rounded end with said trigger and at a second tapered end with said Y-shaped grip; whereby said trigger is actuated to force said pusher bar means between said aft ends of said arms to close said Y-shaped grip.
