Surgical clip applier with integrated cutter
First Claim
1. A surgical clip applier, comprising:
- a housing;
at least one handle pivotably connected to the housing;
an outer support channel extending distally from the housing;
a drive channel slidably disposed within the outer support channel, the drive channel in mechanical communication with the at least one handle;
a jaw assembly including a first and second pair of jaws extending from an end of the outer support channel, the first and second pair of jaws disposed in a parallel configuration, each of the first and second pair of jaws configured to receive a respective clip therein, wherein the jaw assembly is operable to effect formation of each respective clip in response to movement of the at least one handle of the drive channel, wherein at least one jaw member of each of the pair of jaws includes a curved distal end, the curved distal end extending towards the opposite one of the at least one jaw member, the curved distal end configured to retain tissue therein;
a cutting mechanism disposed within a gap defined between the first and second pair of jaws, the cutting mechanism extending from an end of the outer support channel and including a pair of elongate members capable of movement relative to each other, wherein the cutting mechanism is capable of operation independent of the at least one handle; and
a shuttle slidably disposed within the outer support channel, the shuttle being in mechanical cooperation with the cutting mechanism, wherein the shuttle includes an actuating pin disposed on opposing sides of a proximal end thereof and a V-shaped notched defined through opposing sides of a distal end thereof, the V-shaped notch configured to engage the pair of elongate members of the cutting mechanism.

Abstract
A surgical clip applier is provided including a housing, at least one handle pivotably connected to the housing, an outer support channel extending distally from the housing, a drive channel slidably disposed within the outer support channel, a jaw assembly including a first and second pair of jaws extending from an end of the outer support channel in a parallel configuration, and an integrated cutting mechanism disposed within a gap defined between the first and second pair of jaws. The jaw assembly is capable of effectuating formation of a pair of clips disposed within a respective first and second pair of jaws in response to movement of the at least one handle and the cutting mechanism is independently operable of the at least one handle. At least one jaw member of each of the pair or jaws includes a curved distal end. A method of operating same is also provided.

9. A method of ligating and transecting tissue, comprising:
-
selecting a surgical clip applier including; a housing; at least one handle pivotably connected to the housing; an outer support channel extending distally from the housing; a drive channel slidably disposed within the outer support channel, the drive channel in mechanical communication with the at least one handle; a jaw assembly including a first and second pair of jaws extending from an end of the outer support channel, the first and second pair of jaws disposed in a parallel configuration, each of the first and second pair of jaws configured to receive a respective clip therein, wherein the jaw assembly is operable to effect formation of each respective clip in response to movement of the at least one handle and the drive channel, wherein at least one jaw member of each of the pair of jaws includes a curved distal end, the curved distal end extending towards the opposite one of the at least one jaw member such that tissue is retained therein; a cutting mechanism disposed within a gap defined between the first and second pair of jaws, the cutting mechanism extending from an end of the outer support channel and including a pair of elongate members capable of movement relative to each other, wherein the cutting mechanism is capable of operation independent of the at least one handle; and a shuttle slidably disposed within the outer support channel, the shuttle being in mechanical cooperation with the cutting mechanism, wherein the shuttle includes an actuating pin disposed on opposing sides of a proximal end thereof and a V-shaped notched defined through opposing sides of a distal end thereof, the V-shaped notch configured to engage the pair of elongate members of the cutting mechanism; loading a pair of clips within a respective first and second pair of jaws; advancing first and second pair of jaws of the clip applier within an incision of a patient; disposing target tissue into the jaw assembly and into the cutting mechanism; actuating the at least one handle to advance the drive channel, wherein advancing the drive channel causes the first and second pair of jaws to move from an open position to an approximated position, thereby effectuating formation of the pair of clips; and actuating the cutting mechanism independent of the at least one handle, thereby transecting the target tissue. - View Dependent Claims (10, 11)

12. A surgical clip applier, comprising:
-
a housing; at least one handle pivotably connected to the housing; an outer support channel extending distally from the housing; a drive channel slidably disposed within the outer support channel, the drive channel in mechanical communication with the at least one handle; a jaw assembly including a first and second pair of jaws extending from an end of the outer support channel, the first and second pair of jaws disposed in a parallel configuration, each of the first and second pair of jaws configured to receive a respective clip therein, wherein the jaw assembly is operable to effect formation of each respective clip in response to movement of the at least one handle of the drive channel, wherein at least one jaw member of each of the pair of jaws includes a curved distal end, the curved distal end extending towards the opposite one of the at least one jaw member, the curved distal end configured to retain tissue therein; a cutting mechanism disposed within a gap defined between the first and second pair of jaws, the cutting mechanism extending from an end of the outer support channel and including a pair of elongate members capable of movement relative to each other, wherein the cutting mechanism is capable of operation independent of the at least one handle, and a shuttle slidably disposed within the outer support channel, the shuttle being in mechanical cooperation with the cutting mechanism, wherein the shuttle includes an actuating pin disposed on opposing sides of a proximal end thereof and advancement of the shuttle causes the V-shaped notch to engage a proximal end of each of the pair of elongate members, thereby causing the distal end of each of the pair of elongate members to move from a first, open, position, to a second, approximated, position. - View Dependent Claims (13, 14, 15, 16, 17)
