====== Endoscopic sheath ======

Flexible endoscopes are exposed to blood, mucus, and other secretions during procedures. Single-use sheaths are designed to prevent contact between contaminants and reusable endoscope components

The usefulness of the [[endoscopic]] [[sheath]] is underreported in the [[literature]].

In addition to protecting the surrounding [[brain parenchyma]] when inserting the [[endoscope]], the endoscopic sheath is a very useful tool to retract neurovascular structures, achieve [[hemostasis]], and create adequate working space within narrow [[ventricle]]s. The sheath can be moved within the [[ventricular system]], and the [[endoscope]] can be moved independently within the sheath. These movements represent all the advantages of the endoscopic sheath.

Marx and Schroeder from the Department of Neurosurgery, University Medicine [[Greifswald]]. used an endoscopic sheath in ∼ 300 intraventricular [[neuroendoscopic procedure]]s and consider the sheath an essential part of a ventriculoscopic system. Proper use of the sheath can help avoid or manage endoscopic [[complications]]
