Abstract
A staple cartridge assembly for use with a surgical stapler and surgical stapling systems are disclosed. The staple cartridge comprises a cartridge body comprising a proximal end. A plurality of staples. A plurality of electrical contacts positioned at the proximal end of the cartridge body and electrically coupleable to the electrical connector upon the installation of the replaceable staple cartridge assembly in the end effector along a distal-to-proximal installation motion and electrically decoupleable from the electrical connector upon removal of the replaceable staple cartridge assembly from the end effector along a proximal-to-distal removal motion.
Claims14
A surgical stapling assembly, comprising:
- a shaft;
- an articulation joint;
- an electrical connector;
- and
- an end effector attached to a distal end of the shaft, wherein the end effector is articulatable relative to the shaft, and wherein the shaft comprises:
- a first jaw;
- a second jaw movable relative to the first jaw;
- and
- a replaceable staple cartridge assembly, comprising:
- a cartridge body comprising a proximal end;
- a plurality of staples;
- and
- electrical contacts positioned at the proximal end of the cartridge body and electrically coupleable to the electrical connector upon installation of the replaceable staple cartridge assembly in the end effector and electrically decouplable from the electrical connector upon removal of the replaceable staple cartridge assembly from the end effector, wherein the electrical contacts are positioned on a proximal face of the cartridge body adjacent a longitudinal slot of the cartridge body, and wherein the electrical connector faces distally toward the proximal face of the cartridge body.
A surgical stapling assembly, comprising:
- a shaft;
- and
- an end effector attached to the shaft, wherein the end effector comprises:
- a first jaw;
- a second jaw movable relative to the first jaw;
- a channel;
- an electrical connector;
- and
- an anvil comprising a proximal end, wherein the proximal end comprises downwardly-extending flanges, wherein each downwardly-extending flange comprises a distal end, and wherein the electrical connector is proximal to the distal ends of the flanges;
- a replaceable staple cartridge assembly configured to be installed into the channel, wherein the replaceable staple cartridge assembly comprises:
- a cartridge body, comprising:
- a deck surface;
- a proximal cartridge body end;
- and
- a plurality of staple cavities defined in the deck surface;
- and
- electrical contacts positioned at the proximal cartridge body end of the cartridge body and electrically coupleable to the electrical connector upon installation of the replaceable staple cartridge assembly into the channel and electrically decouplable from the electrical connector upon removal of the replaceable staple cartridge assembly from the channel, wherein the electrical connector comprises a flex cable attached to a sidewall of the channel, and wherein the flex cable comprises a coiled section.
A replaceable staple cartridge assembly for use with a surgical stapling end effector having a cartridge channel and an electrical connector, wherein the replaceable staple cartridge assembly is configured to be installed into the cartridge channel, the replaceable staple cartridge assembly comprising:
- a cartridge body comprising:
- a proximal end;
- a plurality of staples;
- and
- electrical contacts positioned at the proximal end of the cartridge body and electrically coupleable to the electrical connector of the end effector upon installation of the replaceable staple cartridge assembly into the cartridge channel of the end effector and electrically decouplable from the electrical connector upon removal of the replaceable staple cartridge assembly from the cartridge channel, wherein the replaceable staple cartridge assembly further comprises a cartridge nose and a distal sensor plug positioned within the cartridge nose, wherein the cartridge nose comprises a distal-facing surface comprising distal electrical contacts electrically coupled with the electrical contacts positioned at the proximal end of the cartridge body, and wherein the distal sensor plug is in electrical communication with the distal electrical contacts.
