Abstract
A laparoscopic stapler for stapling tissue is proved. The laparoscopic stapler comprises a flippable anvil assembly and a flippable staple housing assembly which can be moved with respect to the flippable anvil assembly, wherein the anvil assembly and the staple housing assembly are respectively configured to be operable in a first configuration and a second configuration, wherein in the first configuration, the anvil assembly and the staple housing assembly both have a low profile so that the anvil assembly and the staple housing assembly can be delivered separately through a 12 mm trocar, and in the second configuration, the anvil assembly and the staple housing assembly has a high profile for performing tissue stapling.
Claims20
A laparoscopic stapler for stapling tissue, comprising:
- (a) an anvil assembly including;
- (i) an anvil, and
- (ii) an anvil shaft extending proximally from the anvil, wherein the anvil is pivotably coupled to the anvil shaft;
- and
- (b) a staple housing assembly which can be moved with respect to the anvil assembly, wherein the staple housing assembly includes:
- (i) a staple housing, and
- (ii) a housing shaft extending proximally from the staple housing, wherein the staple housing is pivotably coupled to the housing shaft,
- wherein the anvil assembly and the staple housing assembly are respectively configured to be operable in a first configuration and a second configuration, wherein in the first configuration, the anvil assembly and the staple housing assembly are configured to be delivered separately through a trocar, and in the second configuration, the anvil assembly and the staple housing assembly are configured for performing tissue stapling,
- wherein the anvil extends non-perpendicularly relative to the anvil shaft when in the first configuration, wherein the anvil extends perpendicularly relative to the anvil shaft when in the second configuration.
A surgical system comprising:
- (a) a surgical stapling instrument, comprising:
- (i) an anvil assembly, and
- (ii) a staple housing assembly movable relative to the anvil assembly and configured to drive a plurality of staples toward the anvil assembly, wherein the staple housing assembly includes:
- (A) a staple housing, and
- (B) a housing shaft extending proximally from and pivotably coupled to the staple housing such that the staple housing is configured to transition from a first staple housing configuration to a second staple housing configuration in which the staple housing extends perpendicularly relative to the housing shaft;
- and
- (b) a trocar having a trocar channel, wherein the staple housing assembly is sized to fit within the trocar channel when the staple housing is in the first staple housing configuration.
A laparoscopic stapler for stapling tissue, comprising:
- (a) an anvil assembly including:
- (i) an anvil, and
- (ii) an anvil shaft extending proximally from the anvil, wherein the anvil is pivotably coupled to the anvil shaft;
- and
- (b) a staple housing assembly which can be moved with respect to the anvil assembly, wherein the staple housing assembly includes:
- (i) a staple housing, and
- (ii) a housing shaft extending proximally from the staple housing, wherein the staple housing is pivotably coupled to the housing shaft,
- wherein the anvil assembly and the staple housing assembly are respectively configured to be operable in a first configuration and a second configuration, wherein in the first configuration, the anvil assembly and the staple housing assembly are configured to be delivered separately through a trocar, and in the second configuration, the anvil assembly and the staple housing assembly are configured for performing tissue stapling,
- wherein the staple housing extends non-perpendicularly relative to the housing shaft when in the first configuration, wherein the staple housing extends perpendicularly relative to the housing shaft when in the second configuration.
