Problems solved by technology

[0003] In order to scan and pre-examine the organs layer by layer, it is necessary to move the probe to scan the organs layer by layer. However, due to the fixed length of the pipes of the current endoscope, when moving the probe, more pipes must be inserted into the human body. , very inconvenient to operate

Abstract

The invention provides a lens assembly of an endoscope. When the pipe needs to be contracted, the electromagnet is energized, and the steel ring adjacent to the unit tube at the rear end is attracted by the electromagnet and magnetically connected to the driving The folding part is elastically folded, and the outer pipe shrinks. At the same time, because the inner pipe is a foldable hose with corrugated folds on the side wall, when the outer pipe shrinks, it can also drive the inner pipe to shrink. When the pipe is long, it is only necessary to disconnect the electric current of the electromagnet, and the folded part returns to its original shape under the action of its own elastic force. The outer pipe is elongated, and the inner pipe is elongated accordingly. The method of the telescopic pipe in the present invention is simple and easy to operate. It can be popularized and used in a large number in the field of endoscopy.

Description

technical field [0001] The invention relates to the field of endoscopes, in particular to an endoscope lens assembly. Background technique [0002] Endoscope is a detection instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software, including image sensors, optical lenses, light source lighting, and mechanical devices. Natural orifices into the body. When in use, the probe of the endoscope used to scan the internal organs of the human body is introduced through the working channel of the endoscope to scan the pre-examined organs, and the changes in the relevant parts can be directly peeped. The quality of the image obtained by the probe will directly affect the quality of the image. The effect of the use of the endoscope, for example, with the help of the endoscope, doctors can observe ulcers or tumors in the stomach, and formulate the best treatment plan accordingly. [0003] In order to scan and pre-exami...
