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.

Surgical access device having a variable tissue approach angle

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.

Surgical end effector loading device and trocar integration

A surgical instrument includes a body, a shaft, and an end effector that is operable to compress, staple, and cut tissue. The end effector includes an anvil and a cartridge. The anvil has a curved tip. The curved tip is elastically deformable from a biased curved position when the tip is subject to a force, such as the force exerted on the anvil when tissue is clamped between the anvil and cartridge. The curved and deformable features of anvil provide for an end effector with improved visualization and maneuverability, in particular during procedures involving marching.

Surgical stapler with elastically deformable tip

A surgical instrument includes a body, a shaft, and an end effector that is operable to compress, staple, and cut tissue. The end effector includes and anvil and a cartridge. The anvil has a body and a modular releasable curved tip that connects with the body. The curved tip is elastically deformable in response to force exerted on the curved tip when tissue is clamped between the anvil and cartridge. The curved and deformable features of anvil provide for an end effector with improved visualization and maneuverability, in particular during procedures involving marching. The modular nature of the curved anvil tip provides for an end effector that allows anvil tip replacement due to wear or interchangeability based on a user preference or procedure.

Surgical stapler with insertable distal anvil tip

Devices and methods for organizing a plurality of end effectors and selectively delivering them through surgical trocars are described herein. In one embodiment, a surgical end effector loading device is provided that includes at least one mating element to interface with a surgical trocar, a deployment lumen positioned to align with a working channel of a surgical trocar, an end effector repository having a plurality of end effector lumens formed therein to receive end effectors, the repository being configured to selectively align any of the plurality of end effector lumens with the deployment lumen, and an advancer coupled to the repository and configured to advance an end effector from the repository through the deployment lumen.

Surgical access devices having a variable tissue approach angle

Surgical access devices having adjustable suture paths

Surgical devices and methods are described. The loading devices can include an elongate shaft extending distally from a housing and a hinge can be disposed between the elongate shaft and an articulating distal portion. The articulating distal portion can hold an end effector to be loaded onto a surgical device. The loading device can have features for stabilizing and holding the distal portion at a particular angular position relative to the elongate shaft, such as washers having protrusions that seat in corresponding recesses formed in the hinge. During articulation of the distal portion, an articulation rack can be advanced which can deform the protrusions on the washers. The washers can rotate and seat in the recesses at the next angular position and change the degree of articulation. The deformable washer and corresponding recesses can apply a biasing force that holds the articulating distal portion in a desired angled position.
