Multiple-blade retractor
First Claim
1. A surgical retractor for inserting into an opening in a patient comprising:
- a first elongated member having a proximal end, a distal end and a projection, a second elongated member having a proximal end, a distal end, a recess and a projection, the projection of the first elongated member being positioned in the recess of the second elongated member when the second elongated member is connected to the first elongated member via a pivot pin, the pivot pin passing through the projections of the first and second elongated members;
a third elongated member having a proximal end and a distal end, wherein the third elongated member is connected to the first and second elongated members at the pivot pin connecting the first and second elongated members and wherein the third elongated member is also connected to the first elongated member via a first link and to the second elongated member via a second link;
a first blade having a first end and a second end, the first end of the first blade being directly connected to the distal end of the first elongated member, the second end of the first blade being configured to be insertable into the opening in the patient;
a second blade having a first end and a second end, the first end of the second blade operatively associated with the distal end of the second elongated member, the second end of the second blade being configured to be insertable into the opening in the patient; and
a third blade having a first end and a second end, the first end of the third blade operatively associated with the distal end of the third elongated member, the second end of the third blade being configured to be insertable into the opening in the patient;
wherein;
the first and second elongated members engage each other so that movement of the proximal ends of the first and second elongated members towards each other causes the distal ends of the first and second elongated members to move away from each other.

Abstract
A retractor with multiple blades for use in surgery. The retractor may comprise first and second elongated portions which are pivotally connected to each other. A first blade may be connected to the first elongated portion and a second blade may be connected to the second elongated portion. The retractor may also comprise a sliding bar having a third blade. The sliding bar may be associated with the first and second elongated portions such that movement of the elongated portions relative to each other may result in movement of the sliding bar and, consequently, movement of the third blade relative to the first and second blades. In one embodiment, the retractor may comprise a tension limiting device so that the third blade may remain relatively stationary as the first and second blades are moved. The retractor may also comprise a fourth blade operatively connected to the first and second elongated portions. The fourth blade may be moved independently of the other blades or may move with the other blades. Also disclosed is a method of retracting tissue.
