Articulating surgical stapling apparatus with pivotable knife bar guide assembly
A surgical stapling apparatus includes a shaft assembly, an end effector secured to the shaft assembly, a firing assembly, and an articulation assembly. The firing assembly includes a drive beam and a flexible knife bar assembly that are selectively advanceable through the end effector for firing the end effector. The articulation assembly has an articulation link assembly and a pivotable bar guide assembly. The articulation link assembly is coupled to the end effector and actuatable to cause the end effector to articulate relative to the shaft assembly. The pivotable bar guide assembly supports the flexible knife bar assembly and includes a proximal guide assembly and a distal guide assembly that are pivotably coupled together. The proximal guide assembly is pivotably coupled to the shaft assembly. The distal guide assembly is pivotably coupled to the end effector.
END EFFECTORS, SURGICAL STAPLING DEVICES, AND METHODS OF USING SAME
An end effector for stapling and cutting an anatomical structure includes an anvil, a cartridge, and a blade. The anvil has an anvil face and a plurality of staple pockets positioned on the anvil face. The cartridge has a cartridge face defining a cartridge blade channel, the cartridge being configured to retain a plurality of staples. Each of the plurality of staples comprises a first staple leg, a second staple leg, and a crown connecting the first and second staple legs and having a midpoint. Each of the plurality of staples comprises an open staple configuration and a closed staple configuration where a first portion of the first staple leg and a second portion of the second staple leg are bent relative to the crown such that the first portion of the first staple leg and the second portion of the second staple leg cross the midpoint of the crown.
SURGICAL RELOADABLE CARTRIDGE ASSEMBLY
The present disclosure includes apparatuses for a surgical reloadable cartridge assembly. An example apparatus includes a lock slider and a blade lock configured to actuate radially between a first position that locks a blade in a secure position and a second position that allows the blade to move longitudinally.
ADVANCING A TOOTHED RACK OF A SURGICAL HANDLE ASSEMBLY
The present disclosure includes apparatuses for a surgical handle assembly. An example apparatus includes a toothed rack, a movable handle member, a driving pawl configured to engage the toothed rack and advance the toothed rack in a linear distal direction in response to a movable handle member advancing in a proximal direction and a latch configured to engage the toothed rack and advance the toothed rack in a linear proximal direction in response to the movable handle member advancing in a distal direction.
SYSTEM AND METHOD FOR DETERMINING TOOL POSITIONING, AND FIDUCIAL MARKER THEREFORE
A spatial orientation determining system includes an imaging device configured for obtaining an image of a surgical site, a surgical tool defining a central axis, a processor, and a memory. The surgical tool configured for operating at the surgical site and disposed thereon, a fiducial marker generated by a machine learning network. The fiducial marker includes a distinct pattern. The memory, includes instructions which when executed by the processor, cause the system to: access an image from the imaging device, the image including a portion of the fiducial marker; determine a spatial positioning of the surgical tool based on at least a visible portion of the fiducial marker and the distinct pattern; and determine, based on the spatial positioning, a positioning, an orientation, and/or a rotational angle of the surgical tool.
SURGICAL HANDLE ASSEMBLY
The present disclosure includes apparatuses for a surgical handle assembly. An example apparatus includes a reloadable cartridge assembly and a surgical handle assembly including a spring positioned in the surgical handle assembly at a proximal end of a toothed rack. Proximal movement of the toothed rack causes the spring to be compressed and allows for complete opening of the reloadable cartridge assembly.
Tool assembly for a surgical stapling device
A surgical device comprising a first jaw member, a second jaw member, a clamping member and a clamp apparatus is disclosed. The clamping member is slidably positioned to translate at least partially through the first jaw member. The clamping member engages the first jaw member and the second jaw member, and has a knife blade for cutting tissue. A flange of the clamping member is configured to engage a cam surface to pivot the second jaw member with respect to the first jaw member from an open position toward an approximated position. The clamp apparatus is movable from a retracted position to an advanced position for preventing a gap between proximal portions of the first jaw member and the second jaw member from exceeding a predetermined distance. The clamping member and the clamp apparatus are separately movable.
Surgical instruments with sensors for detecting tissue properties, and system using such instruments
A system is provided that furnishes expert procedural guidance based upon patient-specific data gained from surgical instruments incorporating sensors on the instrument's working surface, one or more reference sensors placed about the patient, sensors implanted before, during or after the procedure, the patient's personal medical history, and patient status monitoring equipment. Embodiments include a system having a surgical instrument with a sensor for generating a signal indicative of a property of a subject tissue of the patient, which signal is converted into a current dataset and stored. A processor compares the current dataset with other previously stored datasets, and uses the comparison to assess a physical condition of the subject tissue and/or to guide a procedure being performed on the tissue.
Motor-driven surgical cutting instrument
A motor-driven surgical cutting and fastening instrument that comprises an end effector, an electric motor, and a motor control circuit. The motor control circuit is for monitoring a parameter of the electric motor that is indicative of movement of a moveable member of the end effector, and for adjustably controlling the electric motor based on the monitored parameter to thereby adjustably control movement of the moveable member of the end effector during forward rotation of the electric motor.
Adaptor for surgical instrument for converting rotary input to linear output
An adaptor for a powered surgical instrument includes a casing, a cam drum, a first linear driver, and a second linear driver. The cam drum defines and is translatable along a longitudinal axis of the adaptor between a retracted position and an advanced position. The cam drum is being supported for rotation about the longitudinal axis. The cam drum defines first and second radial cam grooves about an outer surface thereof. The first cam groove defines a first profile and the second cam groove defines a second profile. The first linear driver includes a first cam follower disposed in the first cam groove and the second linear driver includes a second cam follower disposed in the second cam groove. The first and second linear drivers are supported for movement between advanced and retracted positions in response to rotation of the cam drum.
