Abstract: An adjunct configured for use with an end effector of a surgical stapler includes a tissue- effecting portion comprising a first material, and at least one movable attachment feature coupled to the tissue-effecting portion and comprising a second material different from the first material. The at least one movable attachment feature is configured to releasably attach the tissue-effecting portion to a stapling surface of the end effector. The tissue-effecting portion is configured to contact tissue clamped by the end effector during closure thereof. The tissue-effecting portion is further configured to be pierced and captured by staples ejected from the end effector into the clamped tissue and thereby reinforce the engagement between the ejected staples and the clamped tissue.

Abstract: An apparatus includes an adjunct body and a plurality of movable members. The adjunct body defines an adjunct surface for contacting a tissue, and the adjunct body is configured to overlie and directly contact a deck of a surgical stapler. The plurality of movable members are coupled with the adjunct body, and each movable member of the plurality of movable members is individually operable to move from a first configuration to a second configuration in response to a firing operation of a surgical stapler. The movable members in the first configuration are configured to couple the adjunct body with the deck, and the movable members in the second configuration are configured to enable the adjunct body to separate from the deck.

Abstract: A surgical instrument includes a battery; a motor powered by the battery; an end effector configured to grasp tissue; and an actuator coupled to the end effector, wherein the motor is configured to cause the actuator to move to yield a surgical treatment of the tissue by the end effector. The surgical instrument further includes a control circuit, configured to: measure an activated battery voltage during an activation of the motor to move the actuator; identify a pulse width modulation (PWM) value associated with the motor activation; calculate an actuator velocity based on a sensed position change of the actuator; and calculate a resistive load force based on the activated battery voltage, the PWM value, and the actuator velocity.

Abstract: A surgical end effector assembly is disclosed. The surgical end effector assembly comprises a shaft, an end effector comprising a first jaw and a second jaw movable relative to the first jaw, and an articulation joint attaching the end effector to the shaft, wherein the articulation joint defines an articulation axis about which said end effector is articulatable relative to the shaft. The articulation joint comprises a first rotary drive member rotatable about the articulation axis and a second rotary drive member rotatable about the articulation axis, wherein the first rotary drive member and the second rotary drive member are rotatable in the same direction to articulate the end effector about the articulation axis. The surgical end effector assembly further comprises a jaw drive output cooperatively driven by the first rotary drive member and the second rotary drive member configured to clamp and unclamp tissue with the second jaw.

Abstract: An apparatus includes a base portion, a shaft, a colpotomy cup, and a colpotomy cup actuation assembly. The colpotomy cup is slidably attached along a length of the shaft and is configured to acuate along the shaft between a proximal position and a distal position. The a colpotomy cup actuation assembly is configured to drive the colpotomy cup between a proximal position and a distal position. The colpotomy cup actuation assembly includes an actuating assembly configured to operatively couple with a drive output of a robotic arm. The colpotomy cup actuation assembly further includes an elongated member extending distally from the actuating assembly and terminating into a distal end fixed relative to the colpotomy cup. The actuating assembly is configured to drive movement of the elongated member relative to the elongated shaft to thereby drive movement of the colpotomy cup between the proximal position and the distal position.

Abstract: Systems, methods, and instrumentalities are disclosed for data processing and creating a record of the processing for archival in metadata associated with the results of the processing. The processing may include transformations of the data. Transforming the data may generate transformed data. The processes performed may be archived, for example, in metadata associated with the transformed data. The metadata may be annotated with information associated with previous transforms performed on the transformed data. The metadata may be stored with the transformed data.

Abstract: A device to process data associated with a surgical event of a surgery may include a processor. The processor may be configured to receive multiple data streams during the surgical event. The processor may be configured to select a primary data stream based on a surgical data interface via which the primary data stream is received. The processor may be configured to select a secondary data stream based on a surgical data interface via which the second data stream is received. The processor may be configured to identify the surgical data interfaces. The processor may be configured to generate situational data associated with the primary data stream based on the secondary data stream. The situational data may indicate a medical decision-making factor of the surgical event. The primary data stream and the situational data may be sent during the surgical event.
