Abstract

The present disclosure describes a surgical retractor system and method. The surgical retractor includes an elongate element defining an operational axis, a first blade secured to the elongate element and comprising a blade face, a second blade moveably secured to the elongate element, wherein the second blade defines a reference point located thereon, and wherein a movement of the second blade moves the reference point in a linear direction parallel to the operational axis and orthogonal to the blade face. A guide element may be removably located within an opening located on either the first blade or the second blade.

Claims (20)

1. A surgical retractor comprising:

an elongate element comprising an elongate element distal end and an elongate element proximal end with a length therebetween, the elongate element defining an operational axis along the length thereof;

a retractor handle secured to the elongate element proximal end;

a first blade having a first upper portion secured to a first arm extending from the elongate element distal end and a first blade portion comprising a first blade face;

a second blade having a second upper portion secured to a second arm extending from the elongate element and a second blade portion having a second blade face that faces the first blade face and an exterior surface opposite the second blade face, wherein the second arm is positioned along the length of the elongate element at a position between the retractor handle and the first arm, the second arm configured to move along the length of the elongate element, wherein the second blade defines a reference point located thereon, and wherein a movement of the second arm along the length of the elongate element moves the reference point in a linear direction parallel to the operational axis and orthogonal to the second blade face, wherein movement of the second arm along the length of the elongate element moves the second arm relative to the retractor handle and relative to the first arm; and

a guide element having blunt tip for insertion through muscle tissue;

wherein the second blade further comprises an opening through the second upper portion to the second exterior surface, the opening dimensioned to receive the guide element therethrough such that surgical retractor is advanceable to a surgical target site with the first blade portion and second blade portion located on the same side of the guide element.

2. The surgical retractor of claim 1 , further comprising means for moving the second blade relative to the elongate element.

3. The surgical retractor of claim 2 , wherein the means comprises at least one of a rack and gear mechanism, a lead screw and nut mechanism, and a linear rail and slide mechanism.

4. The surgical retractor of claim 3 , further comprising a locking element.

5. The surgical retractor of claim 3 , wherein the retractor handle comprises an elongate shape having a length aligned with the operational axis, the elongate shape comprising a substantially circular cross section having a circle center positioned on the operational axis, and

wherein the means for moving the second blade relative to the elongate element comprises a driver handle, and wherein the driver handle comprises a driver handle elongate shape having a driver handle length positioned orthogonal to the operational axis, the driver handle elongate shape comprising a substantially circular cross section having a driver handle circle center positioned on a driver handle axis aligned with the drive handle length, wherein rotation of the driver handle about the driver handle axis activates movement of the second blade relative to the elongate element.

6. The surgical retractor of claim 1 , wherein when the guide element is received in the opening, the guide element is located along the second blade exterior surface.

7. The surgical retractor of claim 1 , wherein the guide element comprises a dissector.

8. The surgical retractor of claim 7 , wherein the dissector is D-shaped.

9. The surgical retractor of claim 8 , wherein a flat side of the dissector faces the second exterior surface of the second blade.

10. The surgical retractor of claim 1 , wherein at least one of the first blade and the second blade define a channel.

11. The surgical retractor of claim 10 , wherein the channel is configured to receive at least partially at least one of a shim, a K-wire, a light source, a probe, and a support frame.

12. The surgical retractor of claim 1 , wherein at least one of the first arm and second arm comprises a connection element for connecting the arm to an articulating arm, wherein said connection element is positioned on the arm at a position between the elongate element and the respective upper portion of the respective blade portion secured to the arm.

13. The surgical retractor of claim 1 , wherein the retractor handle comprises an elongate shape having a length aligned with the operational axis, the elongate shape comprising a substantially circular cross section having a circle center positioned on the operational axis.
