SECONDARY IMAGING ENDOSCOPIC DEVICE

摘要

Described herein are various detachable secondary imaging endoscopic devices that can be used in conjunction with an endoscope to provide additional fields of view so that multiple regions of a body cavity may be imaged simultaneously. In one variation, a secondary imaging endoscopic device comprises an endoscope attachment member configured to be disposed over an endoscope, a first imaging element and a corresponding first light source at a first location on the endoscope attachment member, and a second imaging element and a second light source at a second location that is adjacent to the first location. In some variations, a secondary imaging device comprises a fluid delivery module having one or more ports for fluid delivery. The multiple simultaneous images acquired by the secondary imaging endoscopic device imaging elements and the main endoscope imaging element can be combined or arranged together to form a continuous view of a body cavity.
