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.

主权项

1. A detachable imaging device for use with an endo scope having a front-facing imaging element, the detachable imaging device comprising:
a clip configured to be releasably disposed over a distal portion of an endoscope, the clip comprising a proximal edge, a distal edge, an inner region and an outer region; an imaging module attached to the outer region of the clip, the imaging module comprising a first side-facing imaging element having a first visual axis, a first side light source adjacent to the first imaging element such that the first light source provides illumination for the acquisition of images by the first imaging element, a second side-facing imaging element having a second visual axis that is co-linear with the visual axis of the first side imaging element, and a second side light source located adjacent to the second imaging element such that the second light source provides illumination for the acquisition of images by the second imaging element; a control cable attached to the imaging module for powering and controlling the imaging module separately from the endoscope; a fluid delivery module attached to the clip comprising a first outlet port, a second outlet port and an internal channel connecting the first and second outlet ports, wherein the first port is located proximal to the first side-facing imaging element and the second port is located proximal to the second side-facing imaging element, and wherein the first and second outlet ports are connected via an internal channel; and a fluid conduit connected to the internal channel of the fluid delivery module, wherein the fluid conduit is located along an outer surface and along the length of the endoscope, and wherein the fluid conduit is configured to transport fluid to the fluid delivery module separately from the endoscope.
