Abstract

A surgical instrument (10) for performing an end-to-end anastomosis of first and second luminal structures includes a housing (26) having an actuator (20) attached thereto and a selectively removable loading unit (100) attached to a distal end of the housing which supports any array of surgical fasteners (260) at a distal end thereof. The surgical fasteners are simultaneously deformable upon activation of the actuator such that a distal end (269) of each surgical fastener secures each end of each luminal structure to complete the end-to-end anastomosis wherein the resulting eversion is exterior to the luminal structures.

Claims (20)

1. A surgical instrument for performing an end-to-end anastomosis of first and second luminal structures, comprising:
a housing having an actuator attached thereto;
a selectively removable loading unit attached to a distal end of the housing, the loading unit supporting an array of surgical fasteners at a distal end thereof, the surgical fasteners being simultaneously deformable against a moveable anvil upon activation of the actuator such that upon deformation a distal end of each of the surgical fasteners secures each end of each luminal structure to complete the end-to-end anastomosis.
2. A surgical instrument according to claim 1 wherein the distal ends of each of the surgical fasteners penetrate at least one of the ends of one of the luminal structures.
3. A surgical instrument according to any preceding claim wherein the surgical fasteners include a convexity and a base leg which cooperate after deformation of the surgical fasteners to securely retain the two luminal structures in close abutment with one another.
4. A surgical instrument according to any preceding claim wherein the surgical fasteners include a base leg and a proximal portion, the surgical fasteners being supported in an angular manner relative to a longitudinal axis extending through the loading unit such that, upon deformation, the base legs of the surgical fasteners deform at an angle relative to the proximal portions of the surgical fasteners.
5. The surgical instrument according to any preceding claim wherein the loading unit is comprised of two halves which are pivotable relative to one another.
6. The surgical instrument according to any preceding claim wherein the two halves of the loading unit when closed form an elongated aperture for receiving the first luminal structure therethrough.
7. The surgical instrument according to any preceding claim wherein prior to actuation of the actuator, the two halves of the loading unit are pivotally secured relative to one another and upon actuation of the actuator, the two halves are unsecured allowing the halves to pivot relative to one another to release the first luminal structure from within the aperture.
8. The surgical instrument according to any preceding claim wherein the distal end of the loading unit includes the anvil for retaining the distal ends of the surgical fasteners and for supporting an everted end of the first luminal structure.
9. The surgical instrument according to any preceding claim wherein the anvil includes an angled surface which causes the distal end of the surgical fasteners to deform proximally during firing.
10. The surgical instrument according to any preceding claim wherein the loading unit is disposable.
11. The surgical instrument according to any preceding claim wherein the distal end of the loading unit includes a plurality of elongated channels for supporting the surgical fasteners.
12. The surgical instrument according to any preceding claim wherein each of the channels includes a distal end and a proximal end wherein each distal end of each channel is radially offset from each proximal end such that the proximal and distal ends of the surgical fasteners are supported in a radially offset manner.
13. The surgical instrument according to any preceding claim wherein the surgical fasteners are deformable upon activation of the actuator such that a distal end of each surgical fastener secures each end of each luminal structure to complete the end-to-end anastomosis wherein the resulting eversion is exterior to the luminal structures.
14. The surgical instrument according to any preceding claim wherein the handle includes a locking flange which locks the handle in an actuated configuration.
15. The surgical instrument according to any preceding claim wherein the locking flange is bifurcated.
16. The surgical instrument according to any preceding claim wherein the actuator includes at least one cam member.
17. The surgical instrument according to any preceding claim wherein the actuator includes a cam member having two cam followers which ride along two cam slots defined within the cam member.
18. The surgical instrument according to any preceding claim wherein each cam follower mechanically engages first and second retracting sleeves, respectively, such that movement of each of said cam follower moves a respective retracting sleeve.
19. The surgical instrument according to any preceding claim wherein one of the cam slots includes two cam stages, a first stage for retracting a first retracting sleeve for deformation of the surgical fasteners and a second stage for retracting the first retracting sleeve relative to the second retracting sleeve to unsecure the halves of the selectively disposable loading unit to allow the halves to pivot relative to one another to release the first luminal structure from within the aperture.
20. The surgical instrument according to any preceding claim wherein the housing includes a thumb tab which is movable from a first position for receiving the selectively disposable loading unit to a second position for securing the selectively disposable loading unit.
