摘要:
A surgical access port comprises a wound protector adapted for insertion into a wound in the abdominal wall of a patient. A resilient pad comprising a laminated structure with a plurality of layers of resilient materials is attached to the wound protector. The pad comprises an aperture adapted to receive and seal against a surgeon's arm or surgical instruments and is self-closing in the absence of a surgeon's arm or surgical instrument.

Methods and devices for accessing a body cavity are disclosed. In general, a surgical access device is provided that can include a cannula that defines a working channel that is sized and configured to receive a surgical instrument. A seal can be disposed in the cannula of the surgical access device. In one exemplary embodiment, the seal can be positioned at a point in the cannula that is effective to maintain contact between the seal and an instrument inserted therethrough as the instrument is rotated about that point.

A device for manipulating a magnetic coupling force across tissue in response to a monitored coupling force is described. The device includes a magnetic field source assembly, a positioning assembly operatively connected to the magnetic field force assembly, and a magnetic coupling force monitor. The magnetic field source assembly includes magnets that provide an external magnetic field source for providing a magnetic field across tissue. The positioning assembly adjusts the position of the magnetic field source. The magnetic field creates a magnetic coupling force between the external magnetic field source and an object positioned in use in a patient during a procedure, wherein the object has or is associated with an internal magnetic field.

A surgical devices comprises a roll-up wound protector with a distal ring, a proximal ring, and a flexible sleeve having a length extending between the proximal and distal rings. The proximal ring has proximal, distal, medial, and lateral faces and is rollable to gather the flexible sleeve around the proximal ring and shorten the length of the flexible sleeve. A hand access port comprises a frame circumscribing an aperture. The aperture is aligned with the proximal and distal rings and is adapted to receive and seal against a surgeon's arm. A latching mechanism is connected to the frame and circumscribes the proximal ring, the latching mechanism having an engaged state wherein the hand access port is attached to the proximal ring and a disengaged state wherein the hand access port is not attached to the proximal ring. An actuation ring is operably connected to the latching mechanism to select between the engaged and disengaged states.
