  • Publication number: 20220240923
    Abstract: Surgical access devices having wound closure features incorporated as part of the device are provided. The devices allow suture to be inserted directly into the device and operated to close an opening through which the device is disposed as or shortly after the device is removed from the surgical site. Further, the wound closure features allow for various orientations of wound closure to be achieved by adjusting an angle at which the suture enters tissue surrounding the opening to be closed. Some of the wound closure features provided for include openings formed in both the housing and cannula of the surgical access device, multiple openings formed in one or both the housing and cannula, locations of the openings being adjustable or otherwise movable, and various flexible seals. Other features, as well as methods of closing an opening through which the surgical access device was disposed, are also provided.

  • Publication number: 20210052271
    Abstract: A motorized surgical instrument is disclosed. The surgical instrument includes a displacement member, a motor coupled to the displacement member, a display, and a control circuit coupled to the motor and the display. The control circuit is configured to measure distance traveled by the displacement member over a predetermined period of time, cause the display to present a selection menu indicia that is indicative of a velocity mode, receive a user input corresponding to the velocity mode, and set the motor velocity of the displacement member based on the measured distance traveled by the displacement member over the predetermined period of time and the user input.

  • Patent number: 10912543
    Abstract: Devices and methods for delivering end effectors through surgical trocars are described herein. In one embodiment, a surgical end effector loading device is provided that includes a housing having a distal-facing first portion configured to couple with a proximal end of a surgical trocar, and an elongate second portion protruding distally from the first portion. The second portion can include a lumen formed therein and can be configured to extend into a working channel of the surgical trocar when the housing is coupled thereto. The device can also include at least one mating element coupled to the housing and configured to interface with a complementary mating element of the surgical trocar to restrict movement of the housing relative to the trocar, as well as an end effector retainer coupled to the housing and configured to selectively couple a surgical end effector to the housing.

  • Patent number: 10799257
    Abstract: A surgical instrument includes a body assembly, a shaft assembly that releasably attaches to the body assembly, and an end effector at a distal end of the shaft assembly. The body assembly includes a first electrical contact and a first sealing portion. The shaft assembly includes a second electrical contact and a second sealing portion. The first and second electrical contacts are configured to electrically couple together to establish an electrical connection therebetween when the shaft assembly is attached to the body assembly. The first and second sealing portions are configured to sealingly engage one another when the shaft assembly is attached to the body assembly to establish a liquid-tight seal that surrounds the electrical connection.

  • Patent number: 10702257
    Abstract: Devices and methods for positioning a surgical instrument are described herein. In one embodiment, a positioning device can include a base that can be placed against tissue and a shuttle including a lumen that can receive a surgical instrument. The lumen can be translated in at least two directions relative to the base and an orientation of the lumen relative to the base can be polyaxially adjusted. Further, the device can include a locking mechanism that, upon actuation, prevents both translational movement and polyaxial movement of the lumen relative to the base.
