Flared Cobra Retractors – Left & Right

Left and right retractors can be used with the anterior, posterior or lateral approach to help expose the acetabulum in total hip surgery

Designed by Henry Boucher, MD
Single prong design modification by Walter Frueh, MD


Curved Cobra Retractors

Curved Cobra RetractorsSingle Prong Curved Cobra Retractors

Curved Cobra Retractors

ANTERIOR APPROACH: Placed inferior to the trans-acetabular ligament during exposure and preparation of the acetabular component. The curve and “twist” of the retractor allow for gentle retraction of the medial and inferior soft tissues and skin. Helps provide easier retraction for the assistant on the other side of the operating table.


Curved Cobra Retractors

POSTERIOR APPROACH: Placed over the anterior acetabular wall for supero-anterior translation of the femoral head and neck during acetabular preparation. The prong(s) pierce the capsule over the anterior wall, then the curve and “twist” of the retractor allows for gentle retraction on the femoral neck.

Harwin Modified Cobra Retractor

Designed for use during total hip and knee surgery

Designed by Steven F. Harwin, MD, FACS


Harwin Modified Cobra Retractor

Harwin Modified Cobra Retractor

Harwin Modified Cobra Retractor

The long handle and obtuse angle provide ergonomic leverage—especially helpful for use with obese patients.

 In total hip surgery, the wide, concave blade design allows for enhanced exposure— especially useful in anterior hip surgery with the placement of reamers, and to elevate and expose the proximal femur.

 In total knee surgery, the wide blade of the large retractor spans the prepared box and helps bring the tibia forward. The small retractor helps with retraction of the medial and lateral structures, where the wide, concave blade provides added exposure over standard bent Hohmann retractors. The serrated tip helps improve stability.
