Surgical dilator, retractor and mounting pad

摘要

A retractor having an elongate body that provides access to a surgical location within a patient. The elongate body includes a plurality of segments that are connected to one another through a plurality of ratcheting mechanisms. The ratcheting mechanisms permit relative movement of the segments with respect to one another when expander dilators are inserted within the retractor. The segments are surrounded and retained by a resilient elastomeric sleeve or bands. The distal end surfaces of the segments include thin edges that are configured to mobilize, dissect, split and retract the terminal tissues in the surgical area. The retractor is used in conjunction with a resilient elastomeric pad that is affixed to the patient and firmly engages the outer surface of the elongate body to thereby anchor the retractor to the patient. A separate anchoring device can be used to connect the retractor to the pad.

主权项

1. A device for providing access to a surgical location within a patient, said device comprising:
an elongate body comprised of a plurality of segments, each of said plurality of segments being of a length spanning the distance between a patient's skin surface at a proximal end portion and the surgical area juxtaposed a surgical area at a distal end portion, said plurality of segments include a first pair of elongated members and a second pair of elongated members arranged oppositely about each other, said first pair of segments hingedly cooperating with said second pair of elongated members at along one surface and cooperating with said second pair of elongated members in an interdigiting manner along a second surface.
