A distal end of the spindle is operatively engaged with the pair of jaws to effectuate an opening and a closing of the pair of jaws upon an axial translation of the spindle. The lockout mechanism is in selective engagement with the spindle and includes a first position that enables distal advancement of the spindle and a second position that inhibits distal advancement of the spindle.

Tissue retrieval system with retention features

A tissue retrieval system including a tissue retrieval bag deployable from an introducer and suspended in an open configuration by support arms can include retention features to prevent inadvertent movement of the tissue retrieval bag relative to the support arms. The support arms can include protruding domes, folds, or curls to restrict sliding of the tissue retrieval bag relative to the support arms. Alternately, tension can be maintained in a cord loop coupled to an opening of the tissue retrieval bag to prevent the tissue retrieval bag from inadvertently sliding relative to the support arms.

An instrument comprising a body comprising a distal end spaced apart from a proximal end relative to a longitudinal axis and a handle coupling located near the proximal end, the body defining a channel miming between the distal end to the proximal end; a drive comprising a first connector located adjacent the distal end and adapted to be connected to a driven instrument, a second connector located adjacent the proximal end and adapted to be connected to a driving instrument, and a drive shaft arranged in the channel, the drive shaft coupling the second connector to the first connector; and an adjustable handle located near the distal end, the adjustable handle comprising a grip spacing apart a leading end from a trailing end along a handle axis, the leading end coupling the handle to the handle coupling, the trailing end shaped to define an impaction plate; wherein the adjustable handle is arrangeable relative to the body in a first and a second position, in the first position the leading end is arranged relative to the handle coupling such that the handle axis is offset relative to the longitudinal axis, and in the second position the leading end is arranged relative to the handle coupling such that the handle axis is parallel to the longitudinal axis.

ORIENTATION OF USER- INPUT DEVICES FOR CONTROLLING SURGICAL ARMS
20230000579 · 2023-01-05 ·

A surgical system comprises an articulated mechanical arm comprising arm segments connected serially by arm joints that flex and rotate, and first and second input-devices. The second input-device comprises a handle configurable to be oriented in any orientation in an x-y-z space, and the handle comprises segment members and joint members corresponding to the arm segments and arm joints of the arm. The arm joints can be actuatable by, and have the same degrees of freedom as, the handle joint member. A method of using the surgical system includes retroflecting the arm, transitioning control of the arm from the first input device to the second input device, and performing a surgical action, during which a displacement vector or a reorientation arc of the handle member through the x-y-z space is translated to a corresponding displacement vector or corresponding reorientation arc of the end effector in the same x-y-z space.

Fastener cartridges including extensions having different configurations

A fastener cartridge can include, one, a cartridge body comprising a deck and a plurality of fastener cavities and, two, a plurality of fasteners positioned in the fastener cavities. The cartridge body can further comprise extensions extending from the deck having different sizes and/or configurations. The extensions can control the flow of tissue relative to the deck and/or support the fasteners as they are ejected from the fastener cavities.

Surgical stapling end effector component with tip having varying bend angle

A surgical instrument, operable to compress, staple, and cut tissue, includes a body, a shaft, and an end effector with a pair of jaws. A placement tip that is bent, angled, or curved and 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, such as when the end effector is closed with the jaws in contact or when tissue is clamped between the jaws of the end effector. When the placement tip deflects, relative angles defined in part by the placement tip vary compared to an initial state without the clamping force. Furthermore, 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.

Method of surgical stapling with end effector component having a curved tip

A method of surgical stapling that 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 method includes positioning the end effector at a desired site for surgical stapling. The method also includes controlling one or more of the jaws of the end effector to place the end effector in an open position. The method also includes positioning the end effector such that tissue is located between the jaws. The method also includes clamping the tissue between the jaws by moving at least one of the jaws toward the other jaw. The method also includes advancing a firing beam of the apparatus from a proximal position to a distal position.

Robotic surgical tool having a retraction mechanism

A robotic surgical tool is disclosed. The robotic surgical tool can comprise an end effector comprising a firing member; a drive system responsive to a motor-driven input; and a proximal housing comprising a retraction mechanism. The retraction mechanism can comprise a control responsive to a manual input. The control can be rotatable in a first direction through a retraction motion and rotatable in a second direction through a reset motion. The retraction mechanism can further comprise a clutch coupled to the control. The clutch can be configured to drivingly engage the drive system as the control rotates through the retraction motion to supply a proximal retraction stroke to a firing bar and drivingly disengaged from the drive system as the control rotates through the reset motion to prevent any displacement of the firing bar by the retraction mechanism until the control is reset for a subsequent retraction motion.

Method of hub communication with surgical instrument systems

A method for adjusting the operation of a surgical instrument using machine learning in a surgical suite is disclosed. The method comprises the steps of gathering data during surgical procedures, wherein the surgical procedures include the use of a surgical instrument, analyzing the gathered data to determine an appropriate operational adjustment of the surgical instrument, and adjusting the operation of the surgical instrument to improve the operation of the surgical instrument.
