A specialized neurosurgical tool called the Landolt Spreader is used to carefully divide the transsphenoidal space so that a speculum can be inserted more easily during endonasal hypophysectomy procedures. Its screw-fastened, conical, rubber-protected tips ensure atraumatic tissue manipulation while lowering the possibility of harm. Surgical precision is improved by the instrument's plier-style grip handle, double spring mechanism, and riveted joint, which enable smooth and controlled tip movement.
