Surgical suturing instrument and method of use
First Claim
1. A suturing instrument comprising:
- a handle;
a shaft extending from the handle and having a proximal end and a distal end including an opening;
a first channel adapted to guide a suture wire in movement toward the opening;
a second channel extending from the first channel and shaped to impart a curvature to the suture wire as the suture wire moves in the second channel;
a cutter adapted to cut the suture wire; and
a wire drive located near the distal end of the shaft that is adapted to engage with and move the suture wire in the second channel;
wherein the suture wire forms a wire loop suture when moved out of the opening.

Abstract
A device is disclosed for introducing a flexible elongated element through at least two portions of a subject. The device includes an advancement unit for advancing the flexible elongated element toward the end of the device such that the elongated element may exit from the device with sufficient force to pass through the subject. The device also includes a curved die for imparting a looping configuration to portions of the flexible elongated element exiting the device, and a curved guide for receiving the looped flexible elongated element as it returns to the end of the device. A cutting mechanism is provided to permit the looped flexible elongated element to be separated from the remainder of the flexible elongated element. The cutting mechanism is adapted to deform the trailing end of the looped flexible elongated element so that the trailing end is forced distally, toward the subject being sutured.

1. A suturing instrument comprising:
-
a handle; a shaft extending from the handle and having a proximal end and a distal end including an opening; a first channel adapted to guide a suture wire in movement toward the opening; a second channel extending from the first channel and shaped to impart a curvature to the suture wire as the suture wire moves in the second channel; a cutter adapted to cut the suture wire; and a wire drive located near the distal end of the shaft that is adapted to engage with and move the suture wire in the second channel; wherein the suture wire forms a wire loop suture when moved out of the opening. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A suturing instrument comprising:
-
a handle; a shaft extending from the handle and having a proximal end and a distal end including an opening; a first channel adapted to guide a suture wire in movement toward the opening; a second channel extending from the first channel and shaped to impart a curvature to the suture wire as the suture wire moves in the second channel; a cutter adapted to cut the suture wire; and a wire drive including a cam and a cam follower arranged to cooperate to engage the suture wire, to move in a first direction to move the suture wire in the second channel, and to move in a second direction opposite the first direction, a portion of the wire drive biased toward engagement with the suture wire during movement in the second direction; wherein the suture wire, when moved out of the opening, forms a wire loop suture. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69)

70. A suturing instrument comprising:
-
a handle; a lever movably mounted to the handle; a shaft extending from the handle and having a proximal end and a distal end including an opening; a first channel adapted to guide a suture wire in movement toward the opening; a second channel extending from the first channel and shaped to impart a curvature to the suture wire as the suture wire moves in the second channel; a cutter adapted to cut the suture wire; and a wire drive adapted to move the suture wire in the second channel; wherein suture wire, when moved out of the opening, forms a wire loop suture, wherein movement of the lever in a first direction actuates the wire drive to move the suture wire in the second channel, and wherein the lever is linked to the wire drive so that the lever is also movable in the first direction without actuating the wire drive to move the suture wire. - View Dependent Claims (71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101)

102. A suturing instrument comprising:
-
a handle; a lever movably mounted to the handle; a shaft extending from the handle and having a proximal end and a distal end including an opening; a first channel adapted to guide a suture wire in movement toward the opening; a second channel extending from the first channel and shaped to impart a curvature to the suture wire as the suture wire moves in the second channel; a cutter adapted to cut the suture wire; and a wire drive adapted to move the suture wire in the second channel; wherein suture wire moved out of the opening forms a wire loop suture, and wherein movement of the lever through a range of motion in a first direction actuates the wire drive to move the suture wire in the second channel and actuates the cutter to cut the suture wire such that one complete wire loop suture is formed and cut from suture wire remaining attached to the instrument. - View Dependent Claims (103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133)
