The pituitary rongeur is specifically designed for grasping and removing small pieces of tissue, making it particularly effective during procedures like laminectomies. In these surgeries, the goal is often to relieve pressure on the spinal cord or nerve roots by removing herniated disc materials. The design of the pituitary rongeur allows for precision in accessing and excising the small, often delicate, fragments of the herniated disc without causing undue trauma to surrounding structures.

This tool has a narrow, cupped tip that can easily grasp the tissue, making it ideal for the intricate and confined work required in spinal surgery. Its effectiveness in removing small volumes of disc material is crucial in ensuring a successful laminectomy, where the objective is to restore stability and alleviate pain for the patient. Tools such as the Cobb elevator, while useful for elevating and manipulating tissues, do not serve the same function as the pituitary rongeur in the context of removing herniated disc fragments. Additionally, surgical implants and breast implants are not designed for this type of tissue removal.
