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.

A61B 34/30
A61B 34/00
A61B 34/35
A61B 17/00
A61B 90/00

Abstract:

A computer-assisted device include an actuator and one or more processors. The computer-assisted device is configured to support an instrument having an end effector located at a distal end. To perform an operation with the instrument, the one or more processors are configured to operate the end effector according to a state machine having a first state and a second state. In the first state a velocity set point of the actuator is set to a first velocity. In the second state the velocity set point of the actuator is set to a second velocity lower than the first velocity. The state machine transitions from the first state to the second state when a force or torque applied by the actuator is above a first threshold and transitions from the second state to the first state when the force or torque applied by the actuator is below a second threshold.

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.

Nicholas H. Ragosta - Sunnyvale CA, US

International Classification:

A61B 34/00

Abstract:

A surgical system includes a dynamic preload tension feature for a tensioning element that actuates a distal end comport of a surgical instrument. The surgical instrument includes a chassis at a proximal end of the surgical instrument, drive components mounted in the chassis, a distal end component at a distal end of the surgical instrument, a flexible tensioning element coupled between a first of the drive components and the distal end component, and a dynamic preload tensioner mounted in the chassis and coupled to a second of the drive components. The flexible tensioning element extends along a path. The dynamic preload tensioner is configured to be driven by the second of the drive components to be moved relative to the chassis and is positioned to change the path of the flexible tensioning element as the dynamic preload tensioner moves relative to the chassis.
