Which retractor type is commonly used to access deeper surgical sites?

The Meyerding retractor is specifically designed for access to deeper surgical sites, making it essential in procedures that require visibility and access to areas that are not easily reachable. This retractor features a long handle and a tapered blade that can effectively provide a wider opening while minimizing trauma to surrounding tissues. Its design allows for optimal positioning and stabilization of the surgical site, facilitating the surgeon's ability to work efficiently in deeper areas.

In contrast, the other options serve different purposes. Army navy retractors, while useful for holding back skin and superficial tissues, may not provide the necessary depth required for more invasive procedures. The meniscal probe is primarily used for probing and examining joint structures, rather than retracting tissue. The Kerrison rongeur is designed for cutting and removing bone or tissue, rather than for holding back tissues to improve visibility of deeper surgical sites. Each instrument has its specific roles, with the Meyerding retractor being particularly suited for accessing deeper surgical areas effectively.
