The Hardy Type Transsphenoidal 3-Prong Fork is a specialized surgical instrument used in transsphenoidal surgeries, which are typically performed for accessing the pituitary gland through the sphenoid sinus. This type of surgery is commonly indicated for treating pituitary tumors, cystic lesions, or other conditions affecting the pituitary gland. The 3-prong fork is designed for retracting or grasping tissues, providing a controlled and stable way to manipulate delicate structures in the sphenoid sinus and surrounding areas.
