ENDOSCOPE FOR USE IN MULTI-CHANNEL MINIMALLY INVASIVE CHANNEL

摘要

An endoscope for use in a multi-channel minimally invasive channel, comprising an operating channel (1) and a secondary endoscope (2). The operating channel (1) comprises a primary channel (11), a secondary channel (12) and a handle (13). The primary channel (11) and the secondary channel (12) are rigidly connected to the handle (13). Inlets of the primary channel (11) and the secondary channel (12) are disposed on the handle (13). The secondary endoscope (2) is disposed in the secondary channel (12). The secondary endoscope (2) is provided with a secondary cleaning channel (21) and a secondary optical channel (22) therein, but does not have an instrument channel therein. The secondary endoscope (2) is disposed in the secondary channel (12), such that the secondary endoscope (2) can have an observation function that can replace the observation function of the primary channel (11) and also provide a supplementary effect.
