Fetching device for sucker type bronchoscope

Abstract

The invention provides a fetching device for a sucker type bronchoscope, and relates to the field of tracheal foreign body fetching devices. The fetching device includes a telescopic rod and folding devices; the telescopic rod includes a first rod body and a second rod body; a raised portion is arranged on the center of the first rod body; the first rod body is hollow, and holes are formed in two ends of the first rod body; the second rod body passes through the first rod body and can freely stretch; each folding device includes two folding arms and a rotation shaft, and the folding arms are rotatably connected through the rotation shaft; one end of the folding device is rotatably connected to the raised portion, and the other end of the folding device is rotatably connected to a sliding ring; the sliding ring sleeves the second rod body; and the number of the folding devices is several, and the folding devices are symmetrically arranged with the second rod body as an axis. The fetching device for the sucker type bronchoscope can easily stretch to a trachea; and when the fetching device and foreign bodies are taken out, the telescopic rod slides, the second rod body shrinks, the folding devices are unfolded, the trachea is opened, and the foreign bodies cannot be touched off.

Description

technical field [0001] The invention relates to the field of an object fetcher for tracheal foreign bodies, in particular to a sucker type bronchoscope object fetcher.
