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. An operative dilator adapted for engagement with a device for providing access to a surgical location within a patient comprising:
an elongated body having a length spanning the distance above a patient's skin surface at a proximal end portion and juxtaposed a surgical area at a distal end portion and having an upper proximate end and an opposing lower distal end; said elongated body having a central passageway that extends the entire length of said dilator from said upper proximate end to said opposing lower distal end, said elongated body having an outer wall adapted to conform to an inner surface of a retractor device having a similar configuration as said outer wall, said outer wall including a first pair of opposing semi elliptical surfaces spanning the length of said elongated body from said proximal end to said opposing distal end and a second pair of opposing semi elliptical surfaces spanning the length of said elongated body from said proximal end to said opposing distal end, together said first pair of opposing semi elliptical surfaces and said second pair of opposing semi elliptical surfaces forming a contiguous elongated body outer surface.
