摘要： A surgical portal apparatus includes a housing and a cannula member. The housing includes a seal mount and a flexible housing wall. The cannula member is connected to the housing and defines a longitudinal axis and passageway. The seal mount has an internal seal. The flexible housing wall is dimensioned to permit both axial and radial movement of the seal mount with respect to the longitudinal axis between a first position of the seal mount and a plurality of second positions of the seal mount. The seal mount may be biased by a biasing member toward the first position. In an embodiment, the biasing member is a spring that is engageable with the cannula member and the seal mount.

摘要： A surgical template and method for drilling osteotomies (e.g., holes in a jawbone) and installing one or more dental implants using a surgical template assembly. The surgical template assembly is provided with one or more drill guides and one or more dental implant guides. The guides are positioned in the surgical template assembly by a computer-driven milling machine interfaced with a computer-generated image of a patient's jawbone and a computer-generated simulation of at least one dental implant so that when the surgical template is placed in the patient's mouth a trajectory of the guides in the surgical template into the patient's jawbone corresponds to a trajectory of the computer-generated simulation of the dental implant into the computer-generated image of the patient's jawbone. Preferably, three fiducial markers, provide positional coordination between the CT scan data, the computer-generated simulation of the dental implant, and the computer-driven milling machine.

摘要： A surgical access port includes an access member defining a longitudinal axis and having an interior wall defining a longitudinal opening adapted for passage of a surgical object, an object seal disposed in mechanical cooperation with the access member and configured to create a substantially fluid-tight seal around a surgical object inserted through the object seal and a centering mechanism mounted to the access member proximal of the object seal. The centering mechanism includes at least one centering element extending at least in a general longitudinal direction within the longitudinal opening, and defining proximal and distal longitudinal end segments. The at least one centering element is positioned and dimensioned to engage the surgical object during passage of the object through the longitudinal opening to normally bias the surgical object into general alignment with the longitudinal axis. A locking member is mounted to the distal longitudinal end segment of the at least one centering element. The locking member is adapted for longitudinal movement relative to the longitudinal axis when the surgical object is in generally aligned relation with the longitudinal axis. The locking member is dimensioned to engage the interior wall of the access member upon asymmetrical manipulation of the surgical object relative to the longitudinal axis to substantially lock the centering mechanism and prevent further asymmetrical manipulation of the surgical object until the surgical object is returned to the generally aligned relation with the longitudinal axis under the bias of the at least one centering element.

摘要： An access port includes a housing defining a longitudinal axis and having proximal and distal ends, and an interior wall defining a longitudinal opening adapted for passage of a surgical object, an object seal disposed in mechanical cooperation with the housing and being configured to create a substantially fluid-tight seal around a surgical object inserted through the object seal and a centering mechanism mounted to the housing. The centering mechanism includes at least one centering element extending at least in a general longitudinal direction within the longitudinal opening and a substantially annular ring mounted to the at least one centering element. The at least one centering element is positioned and dimensioned to engage the surgical object during passage of the object through the longitudinal opening and is capable of radial outward deflective movement relative to the longitudinal axis in response to an outward force exerted by the surgical object during eccentric manipulation of the surgical object. The annular ring is adapted for radial movement during corresponding radial movement of the at least one centering element upon eccentric manipulation of the surgical object, to thereby engage the interior wall and apply a generally inward force counteracting the outward force exerted by the surgical object tending to bias the surgical object toward a generally aligned position with respect to the longitudinal axis.
