    摘要: A surgical cannula assembly includes an elongate cannula member having a plurality of longitudinal ribs extending along the longitudinal axis with adjacent longitudinal ribs defining a longitudinal channel therebetween, a fluid port mounted adjacent the proximal end of the cannula member and configured for coupling to a source of inflation fluids, a conduit positioned within at least one longitudinal channel of the cannula member and in fluid communication with the fluid port, and an expandable balloon mounted adjacent the distal end of the cannula member and in fluid communication with the conduit. The expandable balloon is configured to transition from an initial unexpanded condition to an at least partially expanded condition upon passage and entry of inflation fluids from the fluid port, through the conduit and within an internal volume of the expandable balloon.

    摘要: A surgical access system includes a clip, a cannula, and an obturator. The clip includes a first housing half and a second housing half. The first and second housing halves have first end portions pivotably coupled together and second end portions having respective first and second fastener portions. The clip is movable between an open position in which the second end portions are spaced apart from each other and a closed position in which the first and second fastener portions of the second end portions are engaged with each other. The cannula and the obturator are retained between the first and second housing halves when the clip is in the closed position.

    摘要: A surgical access device is disclosed and includes a housing, a cannula, a guide, and an expandable member. The cannula extends distally from the housing and defines a longitudinal axis. A wall of the cannula includes a first slot defined therein. The guide is engagable with the housing and defines a first channel. The first channel is disposed at a non-parallel angle relative to the longitudinal axis. The expandable member is disposed adjacent a distal portion of the cannula and is transitionable between a collapsed configuration and an expanded configuration. A first surgical instrument is insertable through the first channel of the guide and through the first slot of the cannula.

    摘要: A surgical access device includes an instrument valve housing including a cannula extending distally from the instrument valve housing. The cannula defines a longitudinal axis. An anchor is supported at a distal end portion of the cannula. A retainer is configured to be removably engaged with cannula. The retainer includes a first member defining a semi-circular shape. The first member defines a first arm having a first lateral surface, and a second arm having a second lateral surface. A first magnet is positioned in the first arm and a second magnet is positioned in the second arm. A second member defines a semi-circular shape. The second member defines a third arm having a third lateral surface, and a fourth arm having a fourth lateral surface. A third magnet is positioned in the third arm and a fourth magnet is positioned in the fourth arm.

    摘要: A surgical access assembly includes elongated cannula member having proximal end portion and a distal end portion, a cannula housing coupled to the proximal end portion of the elongated cannula member, a balloon anchor coupled to the distal end portion of the elongated cannula member, and a collar having a port disposed along the elongated cannula member and in fluid communication with the balloon anchor. The port includes a first check valve, a second check valve, an actuatable button, and a release valve. The first check valve is disposed between a first end portion of the port and a second end portion of the port thereby defining a first chamber. The second check valve is coupled to the second end portion of the port and defines a second chamber between the second check valve and the first check valve. The actuatable button is configured to control flow of air into the balloon anchor. The release valve is configured to control flow of air out of the balloon anchor.

    摘要: A surgical access assembly includes a cannula including an elongated shaft and a retention anchor movably positionable along the elongated shaft. The retention anchor includes an annular body and a fixation body. The annular body includes a proximally-facing surface, a distally-facing surface, an inner side surface defining an opening therethrough, and an outer side surface. The fixation body includes a disc secured to the distally-facing surface of the annular body and wings extending radially outwardly from the disc beyond the outer side surface of the annular body. The disc defines an opening therethrough and the elongated shaft extends through the openings in the annular body and the fixation body.
