endoscope

Abstract

The invention provides an endoscope, comprising an endoscope casing, an optical assembly and a drying part; the endoscope casing has a cavity for accommodating the optical assembly, and the drying component is installed in the cavity On the part, the mounting part is arranged on the outer wall of the optical assembly, the inner wall of the cavity of the endoscope housing, or the bracket between the optical assembly and the endoscope housing. In the endoscope provided by the present invention, after the drying component is installed on the mounting part, it is ensured that the drying component is located on the optical path of the endoscope, which effectively avoids the generation of a fog layer on the optical path of the endoscope, and improves the performance of the endoscope. The dryness in the cavity effectively ensures 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.
