A method for deforming a staple comprising a base, a first staple leg, and a second staple leg, wherein the base, the first staple leg, and the second staple leg are positioned within a common plane prior to being deformed, the method comprising positioning the first staple leg within a first cup of a staple pocket, the first cup comprising a first inner surface, applying a first compressive force to the first staple leg to bend the first staple leg toward the base and the second staple leg, contacting the first inner surface with the end of the first staple leg to bend the end of the first staple leg toward a first side of the base, and deforming the first staple leg such that the end of the first staple leg crosses a mid-line of the staple defined between the first staple leg and the second staple leg.

An electrosurgical forceps includes first and second shaft members and first and second jaw members extending distally from the respective first and second shaft members. A pivot couples the first and second shaft members with one another such that the first and second shaft members are movable relative to one another between a spaced-apart position and an approximated position to move the first and second jaw members relative to one another between an open position and a closed position. The jaw members are configured to facilitate tissue treatment, tissue division, and blunt tissue dissection.

A surgical instrument is provided having an actuator mechanism with an integrated extension element. The surgical instrument comprises a handle assembly, an elongate shaft, and an end effector. The end effector comprises a jaw assembly having atraumatic pads to reduce force on grasped tissue. An actuator is movable within the elongate shaft to actuate jaws of the jaw assembly responsive to a movable handle of the handle assembly. The actuator can have an integrated extension element that allows the actuator to translate within the elongate shaft upon application of a relatively low force and translate and extend upon application of a relatively higher force to the actuator to limit the force applied by the jaw assembly. The actuator also utilizes forces stored with the integrated extension element to provide a dynamic amount of force used to grasp the tissue when the tissue volume decreases while in the jaws.

A torque limiter for a surgical screwdriver that includes an outer sleeve (1); a snap sleeve (3), which is arranged in and rotates with the outer sleeve; a rolling element cage (6), which is arranged in the snap sleeve; an inner sleeve (10), which is arranged in the rolling element cage; and a force-transmitting shaft (11), which is received in and rotates with the inner sleeve. The inner wall of the outer sleeve is provided with recesses (8) that extend parallel to a rotational axis of the force-transmitting shaft. The rolling element cage is provided with a plurality of rolling element receiving areas (5), each of which holds a rolling element (4), and with a number of noses (7), which engage into the recesses. The inner sleeve is provided with a plurality of notches (9), which extend in a V-shape parallel to the axis and which receive the rolling elements.

Certain aspects relate to systems and techniques for surgical robotic arm setup. In one aspect, there is provided a system including a first robotic arm configured to manipulate a medical instrument, a processor, and a memory. The processor may be configured to: determine a minimum stroke length of the first robotic arm that allows advancing of the medical instrument by the first robotic arm to reach a target region from an access point via a path, determine a boundary for an initial pose of the first robotic arm based on the minimum stroke length and a mapping stored in the memory, and during an arm setup phase prior to performing a procedure, provide an indication of the boundary during movement of the first robotic arm.

The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. An end effector of the surgical tool is coupled to a tool driver. An actuator is driven by a motor of the tool driver and configured to drive a degree of freedom of the end effector. One or more processors are configured to receive a position command describing a desired position for the end effector, translate the desired position to a command for a joint associated with the end effector, calculate a compensation term to compensate for a source of hysteresis for backlash and/or compliance, and send a motor command for the motor coupled with the actuator based on the compensation term and the command for the end effector.

Techniques for grasp adjustment include a computer-assisted device comprising a repositionable structure configured to support an end effector and one or more processors. The one or more processors are configured to receive one or more images of the end effector; determine, based on the one or more images, at least one of a first length between a proximal end of jaws of the end effector and a proximal end of a grasping zone, a second length corresponding to a length of the grasping zone, a third length between a distal end of the grasping zone and the distal end of the at least one jaw; or an angle between the jaws of the end effector; and adjust a force or a torque magnitude limit used to limit actuation of the end effector based on at least one of the first length, the second length, the third length, or the angle.

Embodiments disclosed herein include devices and methods of using devices for protecting a face and/or head of an individual receiving medical treatment in a supine or reclined position. The device includes a body having a top portion with an exterior surface and a base portion with an interior surface. The top portion includes opposing side edges, the base portion includes opposing bottom side edges extending outwardly from the top side edges. The base portion is flexible and is configured to wrap partially around the individual’s head, while an aperture extends between the exterior surface and the interior surface to provide access to at least one of the individual’s eyes, nose, or mouth. A strap spans the side edges, wraps behind the base portion and the individual’s head, and detachably couples to the exterior surface along a plurality of connection positions along the side edges.

This invention relates generally to a medical device, and more specifically, to a vaginal surgical apparatus. In one embodiment, a vaginal device includes, but is not limited to, a shaft, the shaft including at least a space to at least partially accommodate a cervix; and a slot to secure a tenaculum; and a stopper that is positionably adjustable along at least a portion of a length of the shaft.

Systems, instruments, and methods for performing a medical procedure. The methods comprise: obtaining a surgical instrument that combines a head positioner and a driver into a single integrated part (the driver being at least partially inserted through an elongate aperture formed in the head positioner so as to extend from a proximal end of the head positioner to a distal end of the head positioner); using an actuable structure of the head positioner to limit an amount that the driver can linearly travel in a first direction within the elongate aperture formed in the head positioner; causing a screw to threadingly engage an object via rotation of the driver in at least a first direction around a central axis of the surgical instrument; and changing an orientation of a receiver via rotation of the head positioner about a portion of the driver.
