Methods of using tissue anchors having bi-directional arrays of barbed pins for joining together parallel tissue layers
A method of joining together two tissue layers includes positioning a tissue anchor over a first tissue layer. The tissue anchor includes a plate having top and bottom surfaces, an array of first pins projecting from the bottom surface of the plate that oppose the first tissue layer, and an array of second pins projecting from the top surface of the plate that face away from the first tissue layer. A second tissue layer is placed over the first tissue layer and the tissue anchor so that the second pins oppose the second tissue layer. The second tissue layer is pressed onto the tissue anchor and toward the first tissue layer so that the first pins advance into the first tissue layer and the second pins advance into the second tissue layer for joining together the first and second tissue layers. The plate has second pin apertures and the second pins are free to slide and move independently of one another within the second pin apertures.
Surgeon disengagement detection during termination of teleoperation
A method for disengagement detection of a surgical instrument of a surgical robotic system, the method comprising: determining whether a user's head is unstable prior to disengagement of a teleoperation mode; determining whether a pressure release has occurred relative to at least one of a first user input device or a second user input device for controlling a surgical instrument of the surgical robotic system during the teleoperation mode; and in response to determining the user's head is unstable or determining the pressure release has occurred, determining whether a distance change between the first user input device and the second user input device indicates the user is performing an unintended action prior to disengagement of the teleoperation mode.
STAPLING DEVICE HAVING ACTUATION SLED WITH KNIFE GUARD
A surgical stapling device includes a tool assembly having an anvil assembly, a cartridge assembly, and a drive assembly. The cartridge assembly includes a channel member that defines a recess and a staple cartridge that is releasably received within the recess of the channel member. The staple cartridge includes a cartridge body, staples, pushers, and an actuation sled that supports a knife. The drive assembly has a working member that is movable through the tool assembly to advance the actuation sled through the staple cartridge to actuate the tool assembly. The actuation sled of the staple cartridge includes a guard to shield the knife and minimize any likelihood of injury to medical personnel during installation and replacement of the staple cartridge.
SURGICAL STAPLING DEVICE WITH FIRING LOCKOUT MECHANISM
A surgical stapling device includes a tool assembly and a drive assembly for actuating the tool assembly. The tool assembly includes a cartridge assembly having a staple cartridge and an anvil assembly that supports a lockout mechanism. The staple cartridge includes a cartridge body and an actuation sled and knife assembly that includes an actuation sled and a knife. The actuation sled and knife assembly is movable in relation to the cartridge body to eject staples from the cartridge body and to cut tissue. The anvil assembly supports a lockout mechanism that includes a lockout member that is movable between a locked position and an unlocked position. The drive assembly is movable from a retracted position to an advanced position to move the actuation sled and knife assembly from its retracted position to its advanced position. In the locked position, the lockout member obstructs movement of the drive assembly from its retracted position towards its advanced position.
Safety shields for elongated instruments and related systems and methods
A system for intraosseous access can include an elongated instrument that is positioned within a cannula portion of a cannula assembly. The system can include a shield that is coupled with both the elongated instrument and the cannula assembly when in an unlocked state. The shield can permit proximal movement of the elongated instrument relative thereto when in the unlocked state. The shield can automatically transition to a locked state to attach to a distal end of the elongated instrument to restrict access to a distal tip of the elongated instrument.
Soft tissue cutting instrument with retractable blade or hook
A system and method for cutting soft tissue with a retractable surgical cutting device (10). The device (10) includes a handle (12) having a first channel (24) extending therethrough and a switch (18) located thereon. The switch (18) is movable between a retracted position and an extended position. An actuator (26) with a blade (16) extends through the first channel (24) and connects to the switch (18) within the handle (12). An outer sheath (14) is connected to the handle (12) and surrounds the actuator (26) and at least a portion of the blade (16). A drive mechanism (28) is connected to the switch (18) within the handle (12) such that when the switch (18) moves from the retracted position to the extended position, the actuator (26) moves from a retracted position to an extended position. In the retracted position, the blade (16) can be entirely within the outer sheath (14) and in the extended position, at least a portion of the blade (16) is positioned outside of the outer sheath (14).
TISSUE THICKNESS COMPENSATOR COMPRISING A RESERVOIR
In various embodiments, a tissue thickness compensator can comprise a compressible extracellular matrix and a bioabsorbable material dispersed within the extracellular matrix, wherein the bioapsorption of the bioabsorbable material is configured to leave behind channels in the extracellular matrix. The tissue thickness compensator can also comprise generation means for generating the ingrowth of tissue into the channels. In at least one embodiment, the tissue thickness compensator can comprise dissolvable wicking members which, when dissolved, can leave behind channels in the tissue thickness compensator. In certain embodiments, the tissue thickness compensator can comprise at least one rupturable capsule.
Sleeve For Rotary Surgical Instrument
An instrument sleeve is provided for use with a surgical rotary instrument having a tube extending to a distal tube end, and a cutting accessory having a head and a shank extending from the head adapted to be rotatably supported by the tube of the rotary instrument. The instrument sleeve comprises a sleeve body extending between proximal and distal sleeve portions, a first lumen for receiving at least a portion of the tube of the rotary instrument, and a shield extension coupled to the sleeve body. The shield extension extends between proximal and distal shield portions the proximal shield portion engaged with the distal sleeve portion and adapted to minimize tissue wrap about the cutting accessory shank.
SURGEON DISENGAGEMENT DETECTION DURING TERMINATION OF TELEOPERATION
A method for disengagement detection of a surgical instrument of a surgical robotic system, the method comprising: determining whether a user's head is unstable prior to disengagement of a teleoperation mode; determining whether a pressure release has occurred relative to at least one of a first user input device or a second user input device for controlling a surgical instrument of the surgical robotic system during the teleoperation mode; and in response to determining the user's head is unstable or determining the pressure release has occurred, determining whether a distance change between the first user input device and the second user input device indicates the user is performing an unintended action prior to disengagement of the teleoperation mode.
MEDICAL INTERVENTION DEVICE WITH VERSATILE HANDLE
A medical intervention device may include a distal end comprising a pair of jaws and a handle operably coupled to the distal end. The handle may include a pair of pivoting finger arms each having at least one finger loop, the pivoting finger arms being configured for opening and closing the pair of jaws at the distal end. The handle may also include at least one actuation interface arranged on the handle and in a position distal to the pair of finger arms.
