  2. Gelpi

  3. Skeletal System

The correct answer is: Gelpi

The correct answer is B. Gelpi. A Gelpi self-retaining retractor is a surgical instrument commonly used in orthopedic and neurosurgical procedures to hold back soft tissues and maintain exposure of the surgical site. This type of retractor has sharp, pointed ends that allow for precise positioning and securing of the retractor blades, enabling the surgical team to have optimal visibility and access to the operative area. The other options provided do not refer to a specific instrument associated with self-retaining retraction, making them incorrect in this context.
