20090054734 | ENDOSCOPIC SURGICAL DEVICES - According to an aspect of the present disclosure, an endoscopic surgical device is provided and includes a handle assembly; a tube assembly operatively supported on and extending from the handle assembly, the tube assembly defining a longitudinal axis; an articulation assembly operatively supported on and extending from a distal end of the tube assembly; and a tool assembly operatively supported on and extending from a distal end of the articulation assembly. In use, a rotation of the handle assembly about the longitudinal axis results in a concomitant rotation of the tool assembly; an actuation of the handle assembly in a particular manner results in a concomitant actuation of the tool assembly; and a pivoting of the handle assembly in any off-axis direction relative to the longitudinal axis results in a concomitant articulation of the tool assembly via the articulation assembly. | 02-26-2009 |
20090312773 | ENDOSCOPIC STITCHING DEVICES - The present disclosure relates to devices, systems and methods for endoscopic suturing or stitching through an access tube or the like. An endoscopic stitching device is provided and includes a handle assembly; an elongate shaft supported by and extending from the handle assembly; and an end effector supported on a distal end of the elongate shaft. The end effector includes a neck assembly configured and adapted for articulation in one direction between a substantially linear configuration and an off-axis configuration, and a pair of juxtaposed jaws pivotally associated with one another. Each jaw defines a suture needle receiving recess formed in a tissue contacting surface thereof. | 12-17-2009 |
20100217282 | FLEXIBLE ENDOSCOPIC STITCHING DEVICES - An endoscopic stitching device is provided including a tool assembly having a pair of juxtaposed jaws each defining a needle receiving recess formed in a tissue contacting surface thereof; a selectively rotatably camming hub defining a helical groove formed in an outer surface thereof; a pair of axially translatable needle engaging blades slidably supported, one each, in a respective jaw, each blade having an advanced position wherein a distal end of the blade is engageable with a suture needle, and a retracted position wherein the distal end of the blade is out of engagement with the suture needle, wherein a proximal end of each blade is configured for slidable engagement in the helical groove of the camming hub; and a suture needle operatively associated with the tool assembly. | 08-26-2010 |
20100249498 | Endoscopic Apparatus for Manipulating Tissue - An apparatus for manipulating tissue during a surgical procedure is provided. The apparatus includes a housing including a movable handle and a release mechanism operatively coupled to a distal end of a shaft extending from the housing. The shaft defines an axial passageway configured to support at least a portion of the release mechanism. The present disclosure also provides a detachable clamp assembly operatively connectable to the distal end of the shaft and the release mechanism such that a pair of pivotally connected opposing jaw members are movable from a closed configuration for clamping tissue therebetween to an opened configuration for positioning tissue therebetween when the movable handle is moved from a first position to a second position. The clamp assembly includes a proximal end operatively coupled to a first end of a suture having a second end connected to a needle. | 09-30-2010 |
20100274265 | FLEXIBLE ENDOSCOPIC STITCHING DEVICES - An endoscopic stitching device includes a tool assembly having a pair of juxtaposed jaws pivotally associated with one another, each jaw defining a needle receiving recess formed in a tissue contacting surface thereof; a drive assembly including a pair of concentric, individually rotatably and translatably supported barrels, each barrel defining a central lumen therethrough; and a pair of axially translatable needle engaging blades slidably supported, one each, in a respective jaw. The stitching device further includes a center rod slidably and rotatably disposed through the lumen of the barrels, a distal end of the center rod being operatively engaged with the pair of jaws. | 10-28-2010 |
20110040308 | Endoscopic Stitching Devices - The present disclosure relates to devices, systems and methods for endoscopic suturing or stitching through an access tube or the like. An endoscopic stitching device is provided and includes a handle assembly; an elongate shaft supported by and extending from the handle assembly; and an end effector supported on a distal end of the elongate shaft. The end effector includes a neck assembly configured and adapted for articulation in one direction between a substantially linear configuration and an off-axis configuration, and a pair of juxtaposed jaws pivotally associated with one another. Each jaw defines a suture needle receiving recess formed in a tissue contacting surface thereof. | 02-17-2011 |
20140110453 | Surgical Instrument with Rapid Post Event Detection - A surgical instrument is disclosed, the instrument including: a handle assembly; a jaw assembly including a staple cartridge containing a plurality of staples and an anvil to form the plurality of staples upon firing; a lockout mechanism configured to prevent reuse of the jaw assembly; a drive assembly at least partially located within the handle and connected to the jaw assembly; a motor operatively coupled to the drive assembly; and a controller operatively coupled to the motor, the controller configured to control supply of electrical current to the motor and to monitor a current draw of the motor, wherein the controller is further configured to terminate the supply of electrical current to the motor in response to a drop in the current draw. | 04-24-2014 |
20140367445 | EMERGENCY RETRACTION FOR ELECTRO-MECHANICAL SURGICAL DEVICES AND SYSTEMS - The present disclosure relates to an electromechanical surgical system including a surgical instrument having a controller, and an end effector selectively and removably connectable to the surgical instrument, wherein the controller is configured to enter an emergency retraction mode when at least one input element of the surgical system is incapable of providing control signals to the controller to operate a motor, wherein the emergency retraction mode activates the motor to withdraw a drive assembly from any advanced position thereof. | 12-18-2014 |
20140367446 | METHOD OF EMERGENCY RETRACTION FOR ELECTRO-MECHANICAL SURGICAL DEVICES AND SYSTEMS - The present disclosure relates to an electromechanical surgical system and methods for use thereof including a surgical instrument having a controller, and an end effector selectively and removably connectable to the surgical instrument, wherein the controller enters an emergency retraction mode when at least one input element of the surgical system is incapable of providing control signals to the controller to operate a motor, wherein the emergency retraction mode activates the motor to withdraw a drive assembly from any advanced position thereof. | 12-18-2014 |
