Surgeons conduct a durotomy post-craniotomy (removal of a portion of the skull). A durotomy involves an incision into the dura membrane, a membrane that covers the brain.
In the U.S, there is an estimated case volume of 664,698 cases and 5296 active [neuro]surgeons.
To conduct a durotomy, two essential tools are involved. A scalpel blade and a dura elevator. A few ancillary tools include forceps and tools that irrigate and drain the surgical space.
This means the surgeon must hold both the scalpel and the dura elevator, while another individual must hold the dura membrane taut with forceps and another individual has to irrigate and drain the surgical space. This complicates the surgical space and reduces surgeon control over the area.
Further, interaction between the dura elevator and scalpel blade can occasionally result in the blade slipping and accidentally nicking the upper surface of the brain.
