Flattening device for steel wire of steel wire knitting outer tube in bronchial cannula

Abstract

The invention provides a flattening device for a steel wire of a steel wire knitting outer tube in a bronchial cannula, belongs to the technical field of machinery, and aims to solve the problem that a current forming device is not high in applicability. The flattening device for the steel wire of the steel wire knitting outer tube in the bronchial cannula comprises a rack, wherein forming wheels and material barrels are connected on the rack; the material barrels are used for storing the steel wire wound on the material barrels; a regulating and positioning mechanism is arranged between the forming wheels and the rack; and by virtue of the regulating and positioning mechanism, the forming wheels which are regulated and positioned in position are fixed on the rack. The flattening device for the steel wire of the steel wire knitting outer tube in the bronchial cannula is high in applicability.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a forming device, in particular to a steel wire flattening device of a steel wire braided outer tube in a bronchial intubation tube. Background technique [0002] Gastroscopy is currently the best method for diagnosing gastrointestinal diseases. Ordinary gastroscopy is an intubation-type examination method. It uses a thin, flexible tube to extend into the stomach, and doctors can directly observe gastrointestinal lesions. However, the design of the existing insertion tube is not reasonable enough, the operation is not flexible enough, the diagnosis efficiency is low, the diagnosis takes a long time, and the patient suffers pain for a long time during the diagnosis process. [0003] The gastroscope insertion tube includes a spring tube, a stainless steel mesh tube, a sleeve and a sheath; the stainless steel mesh tube is placed on the spring tube, the sleeve sleeve is placed on the...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that the structure of the above-mentioned patent is relatively complicated, although the forming and cutting action of the flat steel wire can be effectively realized

However, the flat steel wire can only pass through the fixed flattened place, and its applicability is relatively poor for steel wires of different sizes.
