An end effector assembly for an optical surgical instrument includes a jaw member and a plurality of optical elements positioned within a cavity of the jaw member. The jaw member has a tissue contacting surface. The jaw member has a proximal portion that is configured to secure a fiber optic cable thereto such that a distal end of the fiber optical cable extends into the cavity. The plurality of optical elements are arranged in a staircase-like manner that rises towards the tissue contacting surface as the plurality of optical elements extends distally within the cavity. The plurality of optical elements is configured to direct a beam of light exiting the fiber optic cable towards the tissue contacting surface.

A surgical instrument configured for both grasping and cutting operations has a shaft with a push rod extending through it. An end effector on the shaft has a grasping jaw, a cutting jaw, and an intermediate jaw. The grasping jaw forms a grasping device with the intermediate jaw, and the cutting jaw forming a cutting device with the intermediate member. A segment of the shaft proximal to the end effector is axially rotatable between a first position, in which the push rod can advance through the segment to actuate the cutting device, and a second position in which the push rod can advance through the segment to actuate the grasping device.

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.

A surgical extractor including a second arm having a proximal end and a distal end, and a first arm having a proximal end for attachment to an extraction device. The first arm additionally has a distal end for attachment to a first modular jaw. The first arm further includes a transverse opening having fastener structure configured to releasably retain an extraction impactor or an extraction device connector. The surgical extractor additionally includes a link pivotably connected to the first and second arms, the link having a distal end for attachment to a second modular jaw.

A tissue approximation device for wound closure having a first arm having a proximal end and a distal end, a second arm having a proximal end and a distal end, the second arm connected to the first arm. A first rake member is connected to the distal end of the first arm and has a first plurality of tissue engaging members extending therefrom to engage tissue. A second rake member is attached to the distal end of the second arm, the second rake member having a second plurality of tissue engaging members extending therefrom to engage tissue. A transverse bar can extend through the first and second rake members such that the first and second rake members movable along the transverse bar. Systems and methods for wound closure are also disclosed.

Medical systems, devices and methods are provided for engaging tissue, e.g. for clipping tissue, closing a perforation or performing hemostasis. Generally, the medical system including a housing, first and second jaws rotatable relative to the housing, a driver, and an elongate drive wire. The elongate drive wire may be disconnected from the driver, first and second jaws, and the housing, which are left in vivo engaged with the tissue.

An apparatus for operating on tissue includes a body assembly, a shaft, an acoustic waveguide, and an end effector. The end effector includes an ultrasonic blade, a clamp arm, and a blade guard. The ultrasonic blade is in acoustic communication with the waveguide. The clamp arm is configured to pivot toward and away from the ultrasonic blade. The clamp arm has a first tine. The blade guard extends from the shaft. The blade guard has a longitudinally extending arm defining a concave pathway and a second tine located distal to the longitudinally extending arm. The ultrasonic blade is partially housed within the concave pathway. The first tine and the second tine are configured to grasp tissue when the clamp arm pivots toward the ultrasonic blade.

A medical clip for holding a medical device. The medical clip includes a first jaw and a second jaw rotatably coupled to the first jaw, the first jaw and the second jaw being rotatable with respect to each other between a closed position and an open position; an elastomeric insert configured to be positioned between the first jaw and the second jaw. The elastomeric insert defining a cavity having a cavity depth that receives a medical device between the first jaw and the second jaw. In the closed position, a distal face of the first jaw and the second jaw define a distal opening configured to receive a portion of the medical device through the distal opening; and, a proximal face of the first jaw and the second jaw define a proximal opening configured to receive a second portion of the medical device through the proximal opening.

A suturing device comprises a housing (1) having operating handles at one end and two clamping working jaws (2 and 3) at the other end, at least one of which (jaw 3) is mounted for movement relative to the second. The device also comprises: a receptacle (capsules 18) having a quick-setting, biocompatible, fluid material, which is used as a means for fastening tissues, wherein at the outlet of said receptacle is a controllable screen, for example a membrane, which is destroyed when the pressure in the receptacle is increased to a set level; and a mechanism for feeding the fluid material into a suturing zone. The working jaw (3) is hollow, and disposed therein are capsules (18) which comprise the fluid material and communicate, via the outlet, with dies (21) which are designed in a wall of the working jaw (3) that interacts with the suturable tissues. The mechanism for feeding the fluid material is designed to be capable of increasing the pressure inside the capsules (18) and forming streams of the fluid material which pass through the dies (21) at a pressure sufficient for passing through the suturable tissues.

A powered handheld electromechanical surgical device includes a motor configured to drive extension and retraction of a drive component, a sensor configured to sense force exerted on the drive component during extension of the drive component, and a controller including a processor and a non-transitory computer-readable storage medium storing instructions that, when executed by the processor, cause the processor to receive the sensed force from the sensor, control a speed of the motor during extension of the drive component in accordance with the sensed force, determine a speed profile or a force profile during extension of the drive component, and control a speed of the motor during retraction of the drive component in accordance with the speed profile or the force profile.
