A method of surgical stapling uses a surgical instrument operable to compress, staple, and cut tissue. The instrument includes a body, a shaft, and an end effector with a pair of jaws. A placement tip extends distally from one of the jaws of the end effector. The placement tip is elastically deformable when the placement tip is subject to a clamping force. In some instances the placement tip includes an arcuate bend, while in other instances the placement tip is straight. The placement tip can have a variety of non-rectangular lateral cross-sectional shapes. In some instances, the placement tip is made of a material of a specified durometer range and having a high color contrast. A distal end of the placement tip may change position based on the state of deflection of the placement tip in response to the clamping force.

The drug administration device can also be configured to use the key in decrypting data received from the server.

Interconnection of drug administration systems

A surgical system comprising an end effector, a closure driver, a force sensor, and a control circuit is disclosed. The end effector comprises a first jaw and a second jaw rotatable relative to the first jaw between an open position and a closed position. The closure driver is configured to apply a closure force to the second jaw to rotate the second jaw toward the closed position. The force sensor is to measure a parameter indicative of the closure force. The control circuit is to receive an output of the force sensor indicative of the parameter and set a velocity of the closure driver based on the received output and a force threshold.

Surgical system comprising control circuit to set velocity of closure driver based on sensor data

A surgical stapler includes a first elongate member having a distal portion that supports an anvil surface, and a second elongate member having a distal portion configured to receive a staple cartridge. The stapler further includes a pin rotatably coupled with the first elongate member, and a clamp member movably coupled with the second elongate member. The clamp member is operable to releasably capture the pin to thereby clamp the first elongate member against the second elongate member. The pin is configured to rotate relative to the first elongate member in response to being captured by the clamp member.

Clamping assembly for linear surgical stapler

A surgical instrument includes a sled and an end effector. The end effector includes a first jaw, a second jaw movable relative to the first jaw, an anvil, and a cartridge channel. The staple cartridge includes a proximal end, a distal end, a cartridge body, and staples supported in the cartridge body, wherein the sled is movable to deploy the staples from the cartridge body against tissue captured between the staple cartridge and the anvil. The cartridge channel is configured to removably retain the staple cartridge, wherein a load is required to remove the staple cartridge from the cartridge channel, and wherein the sled is configured to reduce the cartridge removal load.

Staple cartridge having retainer movable between configurations

A method of operating a modular surgical system including a control module, a first surgical module, and a second surgical module is disclosed. The method includes detachably connecting the first surgical module to the control module by stacking the first surgical module with the control module in a stack configuration, detachably connecting the second surgical module to the first surgical module by stacking the second surgical module with the control module and the first surgical module in the stack configuration, powering up the modular surgical system, and monitoring distribution of power from a power supply of the control module to the first surgical module and the second surgical module.
