Abstract:

An exemplary surgical apparatus may include a feeder belt; at least one staple including a crown fixed to and frangibly separable from the feeder belt, the crown having a first width, and a free end extending from the crown; and at least one pad wider than the first width, wherein each pad is associated with a corresponding crown. An exemplary surgical method using that exemplary apparatus may include placing the feeder belt in proximity to tissue; penetrating the free end of at least one staple into tissue, such that tissue is positioned between the free end and the crown; compressing the free end of at least one staple toward the crown, such that a compressive force is exerted toward the crown; distributing the compressive force across the pad of at least one staple; and shearing at least one staple from the feeder belt. Another exemplary surgical apparatus may include at least one feeder belt having two lateral edges; staples, where each staple includes a first end frangibly connected to a corresponding feeder belt and a second free end; and where the staples form at least one row, each row including at least two staples; and at least one pad, where each pad is located along a corresponding free end of a corresponding staple.

International Classification:

A61B 17/068
A61B 19/00

US Classification:

227 2, 2271751

Abstract:

Systems and methods are provided for detecting failure in clamping of a material and/or firing of a staple into a clamped material and indicating such failure to a user on a user interface. The system and methods are particularly suited for use with end effectors having closing and/or firing mechanisms coupled to an actuator. By monitoring a driving parameter of an actuator that effects the clamping and/or firing, the systems and methods provide an indication of failure in response to the monitored drive parameter. In some embodiments, an indication of failure is output when the monitored drive parameter is outside an acceptable range of desired driving parameters during clamping and/or firing. The disclosed systems and methods are particularly beneficial when used for minimally invasive surgery.

International Classification:

A61B 17/28

US Classification:

606205

Abstract:

End effectors with closing mechanisms, and related tools and methods are disclosed. The disclosed end effectors may be particularly beneficial when used for minimally invasive surgery. An example surgical tool comprises a first and second jaw movable between a closed grasped or clamped configuration and an open configuration. The tool further comprises a soft grip mode for grasping the tissue at a first force during which a separation parameter between the jaws is measured, and a therapeutic clamping mode in which the jaws clamp on the body tissue at a force greater than the grasping force. The methods comprise grasping the body tissue between jaw members, measuring the separation parameter between jaws, indicating on a user interface the separation parameter for comparison to a desired separation parameter, and then releasing the body tissue for repositioning or therapeutically clamping the body tissue in response to the separation parameter indication.

International Classification:

A61B 17/068

US Classification:

227 2

Abstract:

Systems and methods are provided for detecting misfire of a surgical staple cartridge and for indicating such misfire to a user on a user interface. An actuation force applied to a staple cartridge is measured and compared to a threshold actuation force. In response to the comparison, a controller determines if there has been a misfire of the surgical staple cartridge. A determination that misfire has occurred is made when the measured actuation force is greater than a maximum threshold force or less than a minimum threshold force, and under such circumstances, the controller terminates the staple firing sequence.

Assignee:

Intuitive Surgical Operations, Inc. - Sunnyvale CA

International Classification:

A61B 17/068

US Classification:

2271801, 2271761

Abstract:

Surgical systems and related methods verify the presence of an unfired surgical cartridge mounted to a surgical instrument. The cartridge includes an input that is actuated in a firing direction to operate the cartridge. An actuation input that is limited to less than or equal to a predetermined magnitude is generated. The actuation input includes at least one of a torque or a force. The actuation input is transferred to an output of a surgical instrument to attempt to actuate the output opposite to the firing direction by a predetermined amount. The output is drivingly coupled with the cartridge input when the cartridge is mounted to the surgical instrument. The resulting actuation of the output is measured and compared with a threshold actuation amount. A determination is made that the cartridge is present and unfired when the resulting actuation of the output is less than the threshold actuation amount.

International Classification:

A61B 17/29
A61B 18/14
A61B 17/072

Abstract:

Surgical instruments and assemblies for sealing and cutting tissue monitor jaw angle and/or jaw clamping force to provide feedback to an operator of the surgical instrument indicative of whether the tissue is suitable clamped for sealing and/or cutting. A surgical instrument or assembly includes a jaw operable to clamp tissue, a sealing mechanism, a cutting mechanism, an actuation monitoring assembly, and a feedback assembly. The actuation monitoring assembly monitors jaw angle and/or clamping force. The feedback assembly outputs feedback to the operator, based on the jaw angle and/or clamping force, as to whether the current clamping angle and/or jaw angle is suitable for sealing and/or clamping tissue.

Abstract:

Systems and methods for operating an end effector include an end effector for grasping a material, a drive system coupled to the end effector, and a processor. The processor is configured to use the drive system to grasp a material using the end effector, determine a grasping separation parameter of the end effector, determine, based on the determined grasping separation parameter, a prediction of success or failure in configuring the end effector for firing a staple through the material, and based on the determined grasping separation parameter, output an indicator of whether it is safe to proceed with stapling of the material grasped by the end effector.

Abstract:

A system and method of variable velocity control of an instrument by a computer-assisted device includes a computer-assisted device that includes an actuator and one or more processors. To perform an operation with an instrument coupled to the computer-assisted device, the one or more processors are configured to set a velocity set point of the actuator to an initial velocity, monitor force or torque applied by the actuator to actuate the instrument, when the applied force or torque is above a first force or torque limit, determine whether a total duration of a set of pauses occurring during the operation of the instrument is below a maximum pause threshold, and in response to determining that the total duration is below the maximum pause threshold, pause the operation of the instrument.
