Detailed Description The present disclosure relates to instruments and methods that may be used during surgical procedures, such as endoscopy. Endoscopy generally involves inserting a catheter into a patient to view internal organs or tissues. The endoscope has novel features. Endoscopes are designed to free the hands of a surgeon or other assistant. The endoscope may have features that allow the endoscope to be inserted into the patient and held in place without being held by a surgeon or an assistant. Unique combinations of size, weight, and/or form factor may allow for these attributes. The endoscope may have an electronic housing and a shaf
