Endoscope

Abstract

The invention provides an endoscope, which comprises an endoscope shell, an optical component and a drying component. The endoscope shell is provided with a cavity for accommodating the optical component, the drying component is arranged on aninstalling part in the cavity body.The installing part is arranged on the outer wall of the optical component, the inner wall of the cavity of the endoscopeshell or a bracket between the optical component and the endoscope shell. According to the endoscope, after the drying part is arranged on the installing part, the drying part is ensured to be arranged on the optical path of the endoscope, afog layer is effectively prevented from being generated on the optical path of the endoscope, the dryness of the endoscope cavity body is improved, thereby effectively ensuring the imaging performance of the endoscope.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an endoscope. Background technique [0002] Endoscopes are widely used as current medical instruments. For medical endoscopes, the airtight and waterproof properties of their internal cavity are crucial to their clear imaging. [0003] Endoscopes usually need to be sterilized by high temperature and high pressure before use. Therefore, high temperature and high pressure sterilization is one of the development trends of endoscopes. put forward higher requirements. [0004] However, in actual use, there is still a fog layer on the internal optical path of the endoscope. The reasons for the fog layer inside the endoscope mainly include the following two aspects: 1. The tail end window and front end window of the endoscope are fixedly connected to the endoscope shell by welding or gluing. During long-term use, the welding or gluing The sticky position will produce tiny ...

[0004] However, in actual use, there is still a fog layer on the internal optical path of the endoscope

The reasons for the fog layer inside the endoscope mainly include the following two aspects: 1. The tail end window and front end window of the endoscope are fixedly connected to the endoscope shell by welding or gluing. During long-term use, the welding or gluing The sticky position will produce tiny pores, that is, tiny pores will be generated at the joints where the tail window and the front window are connected to the endoscope shell (this tiny hole does not need to be disassembled for expensive maintenance), and the water vapor in the external environment 2. When the optical components are installed into the cavity of the endoscope shell, the ambient humidity is not well controlled, and there is residual water vapor inside the cavity

The imaging performance of the endoscope is affected by the fog layer on the optical path inside the endoscope.
