What is the primary function of a Charnley retractor?

The primary function of a Charnley retractor is to hold back skin and tissue. This type of retractor is specifically designed to gain and maintain exposure during surgical procedures by keeping the surrounding tissues out of the way. This allows the surgeon to have a clear view and access to the surgical site without obstruction from the skin and soft tissues.

While other instruments may assist with hemostasis, provide access to the abdominal cavity, or retract nerves during spinal surgeries, the Charnley retractor is not specifically designed for those functions. It is best recognized for its effectiveness in general surgery and orthopedic procedures where it is crucial to keep the surgical field clear of extraneous tissue.
