Question: 1 / 400

What does the Murphy Rake Retractor primarily enhance in the surgical field?

Depth of incision visibility

Stability of the tissue

Visibility of the surgical field

The Murphy Rake Retractor is specifically designed to enhance visibility of the surgical field during procedures. Its unique structure allows the retractor to hold back tissues, creating a clear line of sight for surgeons to work effectively. By keeping the surrounding tissues out of the way, it aids in exposing the area of interest, which is crucial for precision in surgical operations.

The other options, while related to aspects of surgery, do not accurately represent the primary function of the Murphy Rake Retractor. For instance, while the retractor may provide some stability to tissue by holding it in place, its primary role is focused on visibility. Similarly, it does not directly control bleeding nor is it intended to improve the depth of incision visibility. The emphasis is predominantly on facilitating a clear view for the surgical team, allowing for better assessment and execution of the procedure.
