Abstract

An improved jaw blade for a surgical clip applier includes first and second legs and first and second jaws integrally connected to the first and second legs, respectively. Each of the jaws includes an inner surface having a channel oriented substantially along a longitudinal axis of the jaw. The channels each have a depth less than the width of the leg of the clip to be received therein. The jaw legs each define a longitudinal axis substantially parallel to one another and a plane therebetween. The jaw legs are movable in the plane between an open position for receiving a clip in the channels thereof, and a closed position for forming the clip received therein. When the jaw legs are in the closed position, the legs of the clip contact with one another and the inner surfaces of the jaws are spaced-apart from one another defining an atraumatic area therebetween.

Claims

1. In an apparatus for applying surgical clips, the apparatus including a handle portion, a body portion extending from the handle portion, a jaw blade extending from the body portion at an end opposite the handle portion, each surgical clip including a pair of legs extending parallel to one another, wherein each leg defines a width as measured in a direction extending orthogonal to a longitudinal axis of the leg and extending orthogonally toward the opposed leg of the surgical clip, the improvement in the jaw blade comprising:

a first leg and a second leg;

a first jaw integrally connected to the first leg, the first jaw including an inner surface oriented toward the second leg, the inner surface of the first jaw defining a channel oriented substantially along a longitudinal axis of the first jaw, the channel of the first jaw having a depth that is less than the width of the leg of the surgical clip to be received therein; and

a second jaw integrally connected to the second leg, the second jaw including an inner surface oriented toward the first leg, the inner surface of the second jaw defining a channel oriented substantially along a longitudinal axis of the second jaw, the channel of the second jaw having a depth that is less than the width of the leg of the surgical clip to be received therein;

wherein the first leg and the second leg each define a longitudinal axis being substantially parallel to one another and a plane therebetween, the first leg and the second leg of the jaw blade being movable in the plane between an open, spaced-apart position for receiving a surgical clip in the channels of the first jaw and the second jaw, and a closed, approximated position for fully forming the surgical clip received within the channels of the first jaw and the second jaw; and

wherein, when the first leg and the second leg of the jaw blade are in the closed, approximated position, the legs of the surgical clip come into contact with one another and the inner surface of the first jaw and the inner surface of the second jaw are spaced-apart from one another defining an atraumatic area between the inner surface of the first jaw and the inner surface of the second jaw.

2. The improved jaw blade of claim 1, wherein each of the jaws defines a clip formation region therein, and wherein the atraumatic area is defined between the clip formation regions of the jaws.

3. The improved jaw blade of claim 2, wherein, in the closed, approximated position, the clip formation regions of the jaws are spaced-apart from one another along lengths of the clip formation regions, and, wherein, in the closed, approximated position, the jaws contact one another in at least one position along lengths of the jaws outside of the clip formation regions.

4. The improved jaw blade of claim 3, wherein at least one of the jaws includes a stop disposed proximally of the clip formation regions of the jaws and extending from the inner surface of the at least one jaw toward the other jaw, the stop configured to contact the other jaw when the jaws are in the closed, approximated position.

5. The improved jaw blade of claim 3, wherein at least one of the jaws includes a stop disposed distally of the clip formation regions of the jaws and extending from the inner surface of the at least one jaw toward the other jaw, the stop configured to contact the other jaw when the jaws are in the closed, approximated position.

6. The improved jaw blade of claim 3, wherein at least one of the jaws includes a first stop disposed proximally of the clip formation regions of the jaws and wherein at least one of the jaws includes a second stop disposed distally of the clip formation regions of the jaws, the first and second stops extending toward the other jaw member and configured to contact the other jaw member when the jaws are in the closed, approximated position such that the clip formation regions of the jaws extend between the first and second stops.

7. In an apparatus for applying surgical clips, the apparatus including a handle portion, a body portion extending from the handle portion, a jaw blade extending from the body portion at an end opposite the handle portion, the improvement in the jaw blade comprising:

a first leg and a second leg;

a first jaw integrally connected to the first leg, the first jaw including an inner surface oriented toward the second leg, the inner surface of the first jaw defining a channel oriented substantially along a longitudinal axis of the first jaw; and

a second jaw integrally connected to the second leg, the second jaw including an inner surface oriented toward the first leg, the inner surface of the second jaw defining a channel oriented substantially along a longitudinal axis of the second jaw;

wherein the first leg and the second leg each define a longitudinal axis being substantially parallel to one another and a plane therebetween, the first leg and the second leg of the jaw blade being movable in the plane between an open, spaced-apart position for receiving a surgical clip in the channels of the first jaw and the second jaw, and a closed, approximated position for fully forming the surgical clip received within the channels of the first jaw and the second jaw; and

wherein, when the first leg and the second leg of the jaw blade are in the closed, approximated position, the inner surface of the first jaw and the inner surface of the second jaw are spaced-apart from one another defining an atraumatic area therebetween.

8. The improved jaw blade of claim 7, wherein each of the jaws defines a clip formation region therein, and wherein the atraumatic area is defined between the clip formation regions of the jaws.

9. The improved jaw blade of claim 8, wherein, in the closed, approximated position, the clip formation regions of the jaws are spaced-apart from one another along lengths of the clip formation regions, and, wherein, in the closed, approximated position, the jaws contact one another in at least one position along lengths of the jaws outside of the clip formation regions.

10. The improved jaw blade of claim 9, wherein at least one of the jaws includes a stop disposed proximally of the clip formation regions of the jaws and extending from the inner surface of the at least one jaw toward the other jaw, the stop configured to contact the other jaw when the jaws are in the closed, approximated position.

11. The improved jaw blade of claim 9, wherein at least one of the jaws includes a stop disposed distally of the clip formation regions of the jaws and extending from the inner surface of the at least one jaw toward the other jaw, the stop configured to contact the other jaw when the jaws are in the closed, approximated position.

12. The improved jaw blade of claim 9, wherein at least one of the jaws includes a first stop disposed proximally of the clip formation regions of the jaws and wherein at least one of the jaws includes a second stop disposed distally of the clip formation regions of the jaws, the first and second stops extending toward the other jaw member and configured to contact the other jaw member when the jaws are in the closed, approximated position such that the clip formation regions of the jaws extend between the first and second stops.
