摘要： The overtube includes a slider within an overtube body, which guides an endoscope and a treatment tool into a body cavity. An endoscope-coupled part and a treatment tool-coupled part are provided inside the slider, and the slider has a dead zone where the forward and backward movement of either the endoscope or the treatment tool does not interlock with the movement of the other and a sensing zone where the forward and backward movement of either the endoscope or the treatment tool interlocks with the movement of the other. A contact surface of the overtube body with a body wall is constituted of a wall surface member that serves as a rotation-preventing wall surface for preventing rotation in a rotational direction with an axial direction of the overtube body as a center.

摘要： An adaptor apparatus comprises a seal assembly housing, a channel, and tapered surfaces. The adaptor apparatus is configured to connect a trocar seal assembly with a robotic trocar cannula and maintain pneumostasis in an insufflated body cavity of a patient. The seal assembly housing comprises an open area sufficient to receive, support, and fix the trocar seal assembly within the adaptor apparatus. The channel provides a pathway for inserting instruments from the trocar seal assembly and into the cannula. The robotic trocar cannula includes an annular flange and a tapered proximal opening. The tapered surfaces of the adaptor apparatus are configured to engage the annular flange and the tapered proximal opening of the cannula. The tapered surfaces of the adaptor apparatus are configured to complement the exterior of the annular flange and the angled opening of the cannula.

摘要： 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.

摘要： A surgical system is disclosed, and includes a surgical fastening apparatus and an access device. The access device defines an internal lumen configured to receive the surgical fastening apparatus. The access device also includes a proximal portion and a distal portion being more flexible than the proximal portion. The access device is reconfigurable between a first condition and a different, second condition in which the distal portion of the access device is configured to fold radially inwardly and proximally upon movement of the surgical fastening apparatus therewith.

摘要： A surgical access port for passage through body tissue to provide access to an underlying tissue site is provided. The access port has a working channel dimensioned for receiving a surgical instrument and a seal assembly for providing a substantial seal before, during and after insertion of a surgical instrument. The seal assembly includes an instrument seal and a zero seal. The instrument seal includes a proximal base that is interconnected to a distal instrument engaging portion by an elongate supporting portion. The engaging portion has a lateral dimension larger than the lateral dimension of the supporting portion forming a bulbous, mushroom-like head. The lateral dimension of the engaging portion decreases toward a distal opening of the instrument seal such that the distal end of the engaging portion is substantially perpendicular to the seal axis. The supporting portion closely conforms to an inserted instrument and serves to align the distal end of the seal.
