  • 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.

  • 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: 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.

  • Patent number: 10265130
    Abstract: Systems, devices, and methods designed to make it easier to couple end effectors to surgical instruments are provided. A variety of features are disclosed, which can be used independently or in conjunction with each other. The resulting benefits include enhanced visualization, more secure coupling, easier communication that coupling has occurred, self-clocking components with respect to each other, and more component modularity. In one exemplary embodiment, an end effector assembly having an end effector and an attachment arm includes a terminal end surface of the attachment arm having a three-dimensional configuration such that a portion of the end surface extends further away from a set location than another portion of the end surface extends from the location. In another exemplary embodiment, end effector assemblies include chambers having curved configurations that assist in self-clocking the assemblies with respect to surgical devices. Other features, devices, systems, and methods are also provided.

  • Patent number: 10251636
    Abstract: Devices and methods for cleaning a surgical device, and or end effectors associated with the device, are provided. In one exemplary embodiment, a surgical device includes a housing, a plurality of shafts extending distally from the housing, a port disposed at a proximal end of the shafts to form a proximal compartment and an end effector receiver disposed at a distal end of the shafts to form a distal compartment. A fluid and/or a vacuum source can be supplied at the port, through the proximal compartment and shafts, and to the distal compartment. The supplied fluid or vacuum source can be effective to remove fluid and/or tissue from the distal compartment. A plurality of seals can be provided on an outer-most shaft in the compartments to seal fluid from the compartments from entering a housing and/or an outside environment. Other devices and exemplary methods are also provided.
