摘要:
An end effector (40) for use by a surgeon to staple an anatomical structure (10) of a patient during a surgical procedure includes an anvil (42) and a cartridge (44). Each of the anvil (42) and the cartridge (44) has a face that is positionable on the anatomical structure (10). The anvil (42) is coupled the cartridge (44) at first and second ends. The anvil (42) is movable relative to the cartridge (44) to define a first gap between the faces at the first ends that is less than a second gap between the faces at the second ends. A stapling device (100) includes the end effector (40) coupled to a manipulator (102) via a shaft (104). The manipulator (102) is accessible to the surgeon. The surgeon uses a clamping mechanism (122) to selectively move the anvil (42) and the cartridge (44) to clamp the anatomical structure (10).

The present disclosure relates to a surgical fastener applying apparatus for applying fasteners to body tissue. The apparatus includes a cartridge receiving half-section defining an elongated channel member configured to releasably receive a firing assembly and a single use loading unit. A lockout structure prevents insertion of the single use loading unit into the channel member after the firing assembly is mounted to the cartridge receiving half-section. Alternatively, the lockout structure prevents full insertion of the firing assembly into the cartridge receiving half-section, if the single use loading unit is not engaged with the firing assembly.

An end effector can comprise, one, a fastener cartridge including a plurality of fasteners stored therein and, two, an anvil configured to deform the fasteners. The anvil can further comprise extensions extending therefrom which can control the flow of tissue relative to the fastener cartridge and/or support the fasteners as they are ejected from the fastener cartridge. The extensions can having different sizes and/or configurations.

A surgical system can include an electric motor, a sensor and a microcontroller in signal communication with the electric motor and the sensor. In various instances, the microcontroller can adjust the velocity of a firing element when the sensor detects a change in current drawn by the electric motor that exceeds a threshold amount.

A surgical instrument for use by an operator in a surgical procedure includes an elongate shaft, an end effector extending from the elongate shaft, and a control system. The end effector is articulatable relative to the elongate shaft between a home state position and an articulated position. The control system includes a processor and a memory coupled to the processor to store program instructions. The processor can alert the operator when the end effector reaches the home state position from the articulated position.
摘要:
The present disclosure provides a surgical instrument control circuit. The control circuit includes a primary processor, a safety processor in signal communication with the primary processor, the safety processor, and a segmented circuit. The segmented circuit includes a plurality of circuit segments in signal communication with the primary processor. The plurality of circuit segments is configured to control one or more operations of the surgical instrument. The safety processor is configured to monitor one or more parameters of the plurality of circuit segments.

A method is disclosed for altering an implantable layer for use with a surgical instrument which includes the steps of obtaining an implantable layer comprised at least partially from a material including a glass transition temperature and a melting temperature, wherein the implantable layer includes a first shape, heating the material to a temperature higher than the glass transition temperature and lower than the melting temperature, manipulating the implantable layer to a second shape different than the first shape, allowing the material to cool below the glass transition temperature, and releasing the implantable layer.
摘要:
An end effector for fastening tissue including an anvil having a deck to support tissue. The deck has a first surface with a first longitudinal row of staple forming pockets, and a second surface, having a second longitudinal row of staple forming pockets wherein the first surface is positioned vertically above the second surface. The end effector also includes a cartridge having plurality of staple cavities arranged in first and second longitudinal rows. The end effector also includes a plurality of staples removably stored within the staple cavities. The staples include a base, a pair of legs extending from the base, wherein each the leg comprises a tip configured to pierce tissue, and wherein each the leg comprises at least one barb extending therefrom. The end effector also has a firing member configured to lift the staple drivers toward the anvil.
