A handle assembly includes two arms and a latching lever. An end effector includes two jaws. A firing assembly includes an actuating beam, a proximal body, and two levers. The actuating beam is slidable relative to the handle assembly and the end effector. The proximal body is coupled to the actuating beam and is housed within either the first arm or the second arm. The first lever is configured to move between a first laterally extending position and a first non-obtrusive position. The first lever is configured to drive the actuating beam and the proximal body relative to the handle assembly in the first laterally extending position. The second lever is configured to move between a second laterally extending position and a second non-obtrusive position. The second lever is configured to drive the actuating beam and the proximal body relative to the handle assembly in the second laterally extending position.
摘要:
A surgical hub is configured to transmit generator data associated with a surgical procedure from a generator of the surgical hub to a cloud-based system. The surgical hub comprises a processor and a memory storing instructions executable by the processor to: receive generator data; encrypt the generator data; generate a message authentication code based on the generator data; generate a datagram comprising: the encrypted generator data, the generated message authentication code, a source identifier and a destination identifier; and transmit the datagram to the cloud-based system. The datagram allows for the cloud-based system to: decrypt the encrypted generator data; verify the integrity of the generator data based on the message authentication code; authenticate the surgical hub as the source of the datagram; and validate a transmission path followed by the datagram between the surgical hub and the cloud based system.
摘要:
A cloud based analytics medical system comprises a processor, a memory coupled to the processor, an input/output interface to access data from medical hub communication devices, each coupled to a surgical instrument, and a database to store the data. The processor aggregates medical resource usage data from the medical hubs. The medical resource usage data comprises data pertaining to medical products and indication of efficiency based on usage, disposal records, and location data describing which medical facility the medical product was allocated to and patient outcome data pertaining to a procedure that utilized the medical product. The processor can determine a correlation between positive outcomes from the outcome data and location data of the medical product, generate a medical recommendation to change a medical resource usage practice based on the correlation, and display the medical recommendation to a medical hub at the local facility.

摘要:
A surgical instrument includes a body assembly, a shaft assembly, and an end effector. The end effector has first and second jaws that are configured to receive a tissue therebetween. The end effector also includes a staple cartridge including a plurality of staples and a hydraulic expandable member that is configured to receive a fluid and thereby expand from a contracted state to an expanded state. The hydraulic expandable member is further configured to direct at least one of the plurality of staples toward an anvil of the first jaw for forcing the at least one of the staples against the anvil and forming the at least one of the staples within the tissue.
摘要:
A surgical instrument. The surgical instrument includes an elongated channel configured to support a staple cartridge, an anvil pivotably connected to the elongated channel, a knife mechanically coupled to the staple cartridge, an electric motor and a control circuit electrically connected to the electric motor. The control circuit is configured to change a firing motion of the surgical instrument based on a combination of events.
摘要:
A surgical instrument comprising an elongate shaft assembly that defines a shaft axis. A surgical end effector is pivotally coupled to the elongate shaft assembly for selective articulation relative to the elongate shaft assembly about an articulation axis that is transverse to the shaft axis. An articulation cable is coupled to the surgical end effector at a point of attachment and is journaled on a proximal pulley that is supported on the elongate shaft assembly. The proximal pulley defines a proximal pulley axis that is located a tension distance from the point of attachment. An articulation driver is coupled to the articulation cable for selectively causing the articulation cable to rotate about the proximal pulley in first and second articulation directions. An adjustable tensioning assembly interfaces with the proximal pulley to selectively adjust the tensioning distance.

An apparatus includes an end effector, a cartridge, and a buttress assembly. The end effector includes an anvil and a lower jaw. The anvil is configured to move toward and away from the lower jaw. The lower jaw is configured to receive the cartridge. The cartridge includes a housing, staples disposed in the housing, and a deck disposed over the staples. The buttress assembly is configured to be attached to either the anvil or the cartridge. The buttress assembly includes an adhesive layer, a film layer, and a buttress body. The adhesive layer is configured to adhere to either the anvil or the deck of the cartridge. The adhesive layer is attached to a first side of the film layer. The buttress body is attached to a second side of the film layer such that the film layer is interposed between the adhesive layer and the buttress body.

A surgical stapler is provided that includes a first jaw and a second jaw. The first jaw includes a proximal end portion and a distal end portion. The second jaw includes a proximal end portion and a distal end portion. The proximal end portion of the first jaw is pivotally mounted to the proximal end portion of the second jaw. A flexible guide is secured to the distal end portion of the first jaw.

A buttress assembly is configured to temporarily adhere to a wet surgical stapler end effector. The buttress assembly includes a buttress body and a humidity tolerant adhesive. The adhesive includes a bioabsorbable polymer having a block configuration selected from the group consisting of A-B-A and A-B-C. The A block is a bioabsorbable homopolymer characterized by a glass transition temperature of at least about 0°C, a crystallinity as measured by X-ray diffraction of at least about 30%, and a melting temperature of at least about 50°C. The B block is a bioabsorbable homopolymer or co-polymer that is characterized by a glass transition temperature of at least about -40°C, a crystallinity as measured by X-ray diffraction of at most about 25%, and2 a molecular weight of from about 20 to about 80kDa. The C block is a bioabsorbable hydrophilic homopolymer or co-polymer that is miscible with water at 37°C.
