Shunt Scissors:

When performing a ventriculoperitoneal shunt surgery, it is necessary to create a subgaleal pocket that is of sufficient size to accommodate a shunt valve. Thus, a special scissors was designed for that specific purpose. These scissors have the cutting blade surfaces facing outward for that purpose vs. standard scissors, since the tissue that needs to be cut to create the shunt valve pocket abuts the outside surfaces of standard scissors blades, and that tissue is too adherent to the skull to separate easily when applying a blunt dissection technique. Second, the dissection motion with standard scissors requires that the surgeon spread apart the scissors handles, rather than using a more easily controlled and powerful closing motion. The technical details are published in Journal of Neurosurgery: " Shunt scissors: technical note". There is a youtube video on how to use the scissor: https://www.youtube.com/watch?v=MSt9aNEfyYo The scissors were designed and created in the prestigious the University of Iowa Neurosurgery Department.
