Multi-nozzle controller for endoscope

The present specification describes a control mechanism for controlling fluid flow through one or more fluid channels that supply fluid to a distal tip of an endoscope. A pump is provided with an endoscope to control the flow of combined fluid from an external source to fluid channels within the endoscope that supply fluid to front and side nozzles of a multi-nozzle endoscope assembly. The pump is preferably a bidirectional pump capable of controlling fluid to the front nozzle or to the front and side nozzles of the endoscope. 本说明书描述了一种用于控制流过一个以上流体通道的流体的控制机构，所述流体通道将流体供给至内窥镜的远侧顶端。泵设有内窥镜以控制从外部源至所述内窥镜内的流体通道的组合的流体的流动，所述流体通道将流体供给至多喷嘴内窥镜组件的前和侧喷嘴。所述泵优选为双向泵，其能够控制至所述内窥镜的所述前喷嘴或至所述前和侧喷嘴的流体。
