Surgical clip applier with high torque jaws
First Claim
1. A surgical clip applying apparatus, comprising:
- a handle portion including a moveable handle and a stationary hand grip;
an elongated body portion extending from the handle portion; and
a jaw blade extending from said elongated body portion and operably connected to the handle portion for selective closure upon, an actuation of the moveable handle, the jaw blade comprising;
a first leg and a second leg, each leg having a jaw integrally connected thereto and extending distally therefrom, each jaw defining a channel oriented substantially along a respective longitudinal axis thereof, wherein the channels are configured to receive a surgical clip therebetween, wherein each jaw is oriented at an angle with respect to a plane defined by the first and second leg; and
an inter-leg engaging member extending from each of the first and second legs and including a distal end engageable with the other of the first and second legs, wherein the distal end of each inter-leg engaging member is at all times at least partially engaged with the other of the first and second legs.

Abstract
Jaw blades for use in surgical clip appliers are disclosed. The jaw blades include a first leg and a second leg, each leg having a jaw integrally connected thereto and at least one inter-leg engaging member that extends from one of the first and second legs and is engageable with the other of the first and second legs. When the at least one inter-leg engaging member is engaged with the other of the first and second legs, a displacement in a first direction of one of the first and second legs causes a first corresponding displacement in the first direction of the other of the first and second legs, and such that a displacement in a second direction, opposite the first direction, of the one of the first and second legs causes a second corresponding displacement in the second direction of the other of the first and second legs.

15. A surgical clip applying apparatus, comprising:
-
a handle portion including a moveable handle; an elongated body portion rotatably mounted to and extending from the handle portion; and a jaw blade for use in a surgical clip applier, wherein the jaw blade is selectively closed upon an actuation of the moveable handle, the jaw blade comprising; a first leg and a second leg, each leg having a jaw integrally connected thereto, and extending distally therefrom, each jaw defining a channel oriented substantially along a respective longitudinal axis thereof, wherein the channels are configured to receive a surgical clip therefrom; and at least one inter-leg engaging member extending from one of the first and second legs, and extending between and engaged with the other of the first and second legs, wherein rotation of the elongated body portion relative to the handle portion causes rotation of the jaw blade. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. An apparatus for applying surgical fasteners or clips, the apparatus comprising:
-
a handle portion including a moveable handle, a body portion extending from the handle portion and including a rotating collar for rotating the body portion relative to the handle portion, and a jaw blade extending from the body portion at an end opposite the handle portion and being selectively closed upon an actuation of the moveable handle, wherein rotation of the body portion relative to the handle portion causes rotation of the jaw blade, the jaw blade having a first leg and a second leg, each leg having a jaw integrally connected thereto, each jaw defining a channel oriented substantially along a respective longitudinal axis thereof, wherein the channels are configured to receive a fastener or clip, a the jaw blade being movable between an open position for receiving the fastener or clip and a dosed position for forming the fastener or clip in response to a movement of the handle portion; and a fastener or clip supply disposed within the body portion, wherein the jaw blade further includes at least one inter-leg engaging member extending between and being adapted to effect an engagement between the first and second legs, wherein vertical displacement in a first direction of one of the first and second legs causes a corresponding displacement in the first direction of the other of the first and second legs, and wherein a vertical displacement in a second direction, opposite the first direction, of one of the first and second legs causes a second corresponding displacement in the second direction of the other of the first and second legs, wherein the jaws are configured to form a surgical clip disposed therebetween. - View Dependent Claims (23, 24)

25. A method for applying surgical clips and performing blunt dissection of tissue, comprising the steps of:
-
providing a surgical clip applier for applying surgical clips, which surgical clip applier includes; a handle portion including a moveable handle; an elongated body portion rotatably mounted to and extending from the handle portion; and a jaw blade supported on a distal end of the elongated body and being selectively dosed upon an actuation of the moveable handle, wherein rotation of the elongated body portion relative to the handle portion causes rotation of the jaw blade, the jaw blade having; a first leg and a second leg, each of the first and second legs having a jaw integrally connected thereto and extending distally therefrom, each jaw defining a Channel oriented substantially along a respective longitudinal axis thereof, wherein the channels are configured to receive the surgical clip therebetween; and at least one inter-leg engaging member extending between and effecting an engagement between the first and second legs, such that a vertical displacement in a first direction of one of the first and second legs causes a first corresponding displacement in the first direction of the other of the first and second legs, and such that a vertical displacement in a second direction, opposite the first direction, of one of the first and second legs causes a second corresponding displacement in the second direction of the other of the first and second legs; and performing a blunt dissection technique utilizing the jaws of the clip applier; and applying a surgical clip to a tissue or vascular target area utilizing the clip applier.

26. A surgical clip applier, comprising:
-
a handle portion including a movable handle; an elongated body portion extending from the handle portion and including a rotating collar for rotating the body portion relative to the handle portion; and a jaw blade supported on a distal end of the elongated body and being selectively closed upon an actuation of the moveable handle, wherein rotation of the elongated body portion relative to the handle portion causes rotation of the jaw blade, the jaw blade comprising; a first leg; a second leg spaced from and parallel to the first leg, the first and second legs defining a plane, each leg including a jaw integrally formed at a distal end thereof and extending distally therefrom, each jaw defining a channel oriented substantially along a respective longitudinal axis thereof wherein the channels are configured to receive a surgical clip therebetween; and at least one inter-leg engaging member extending between the first and the second legs and operatively engaged therewith, wherein the at least one inter-leg engaging member maintains or reduces the loss of co-planarity of the first leg with respect to the second leg. - View Dependent Claims (27, 28, 29, 30)
