Flexible four-directional tube structure of endoscopy

Abstract

The invention discloses a flexible four-directional tube structure of an endoscopy. The flexible four-directional tube structure comprises a plurality of sphere assemblies, a plurality of line bodies and a plurality of elastic assemblies, wherein the line bodies are continuously threaded into holding spaces of the elastic assemblies; the elastic assemblies are continuously embedded into grooves of the sphere assemblies, so that the plurality of sphere assemblies form a tubular body; the tubular body can be bent along with a pull force exerting direction of the line bodies, so that the steering of a lens of the endoscopy is controlled.

Description

technical field [0001] The invention relates to a steering structure of an endoscope lens, in particular to a flexible hose structure of an endoscope that can rotate in four directions. Background technique [0002] The invention of the endoscope allows humans to observe the interior of objects more accurately. For example, in the medical field, it can perform inspections on the esophagus, stomach and large intestine, allowing doctors to accurately determine the type of lesion through the images of the endoscope and the degree of disease development; if it is applied in the industrial field, it can accurately inspect the inside of the engine, or inspect the narrow space of the inspection area, which is difficult to observe. In order to observe images in multiple directions more accurately, today's endoscopes There is a flexible structure at the inner viewing lens, so that the inner viewing lens has the function of turning. However, the current flexible structure mostly uses ...

AI Technical Summary

Problems solved by technology

[0003] 1. The elastic component is a spring. If the spring is used more times, it will easily cause elastic fatigue and break, which will affect the operation of the swing head device and cause great inconvenience to the user.

[0004] 2. The head swing device of the endoscope must be equipped with a two-way flexible body, which not only makes the production process more cumbersome, but also greatly increases the cost

[0005] 3. The head swing device of the endoscope can only turn in two directions, causing inconvenience in use
