Abstract
A surgical retractor device includes a frame and at least one retracting member configured for being secured to the collapsible frame. The retracting member is formed from a spring-biased rotatable member, a tension line secured at a proximal end to the spring-biased rotatable member, and a tissue securing member disposed at a distal end of the tension line. In certain embodiments, the surgical retractor may be collapsible and delivered laparoscopically to the resection site.

A surgical retractor device, comprising:
- a frame configured to expand and contract within a patient, the frame comprising:
- a first sub-frame having a distal end and a proximal end;
- a second sub-frame having a distal end and a proximal end;
- a first pivot point located at the distal end of the first sub-frame and the distal end of the second sub-frame;
- and
- a second pivot point located at the proximal end of the first sub-frame and the proximal end of the second sub-frame,
- wherein rotation of the first sub-frame relative to the second sub-frame about the first pivot point and the second pivot point transitions the frame from a collapsed configuration that permits insertion of the frame into the patient via a single incision and a non-collapsed configuration that permits a tissue operation.
A surgical retractor device, comprising:
- a frame configured to expand and contract within a patient, the frame comprising:
- a plurality of elongate sub-frames, wherein each sub-frame has a distal end and a proximal end;
- and
- a plurality of pivot points located at the distal end and the proximal end of each sub-frame,
- wherein rotation of the plurality of sub-frames about the plurality of pivot points transitions the frame from a collapsed configuration that permits insertion of the frame into the patient via a single incision and a non-collapsed configuration that permits a tissue operation.
A method of treating a patient, comprising:
- making a single incision in the patient to provide access to a tissue located within the patient;
- inserting a surgical retractor in a collapsed configuration through the single incision, wherein the surgical retractor has a plurality of elongate sub-frames with a pivot point at each end of each sub-frame;
- expanding the surgical retractor via rotation of the plurality of sub-frames about the pivot points;
- performing an operation on the tissue while the surgical retractor is in a non-collapsed configuration;
- collapsing the surgical retractor via rotation of the plurality of sub-frames about the pivot points;
- and
- withdrawing the surgical retractor from the patient via the single incision.
