Endoscope, insertion head end and manufacturing method of insertion head end

Abstract

The invention provides an endoscope, an insertion head end and a manufacturing method of the insertion head end. The insertion head end comprises a head end main body, a camera, a light source assembly and a light blocking piece; the camera is arranged in an installation hole of the head end main body, the annular light blocking piece is formed in the installation hole in an injection molding mode, and the light blocking piece surrounds the exterior of the camera so as to prevent stray light from entering the camera; the outer end surface of the light blocking piece is flush with the end faceof the head end main body. According to the insertion head end, the light blocking piece is formed in the installation hole through injection molding, and the outer end surface of the light blocking piece is flush with the end surface of the head end main body, so that tight assembly of the light blocking piece and the head end main body can be ensured, the light blocking piece can block stray light from entering the camera, camera image shooting quality is guaranteed, the surface of the peripheral side structure of the camera can be smooth, obstruction of the light blocking piece to lens flushing liquid is avoided, the lens surface and the peripheral side can be comprehensively cleaned by using the flushing liquid, the cleaning effectiveness is ensured, and normal use of an endoscope andthe safety of the operation process are ensured.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an endoscope, an insertion head end and a manufacturing method of the insertion head end. Background technique [0002] Endoscope is a commonly used medical device, which enters the patient's body through the natural orifice of the human body or through the incision formed by surgery. After the endoscope is introduced into the organ to be detected, the medical staff can directly observe the pathological changes in the relevant parts. [0003] At present, a camera is provided at the end of the endoscope so that the endoscope has the function of image capture. Generally, an aperture stop is provided at the end of the endoscope to prevent stray light from entering the camera and affecting the image quality. However, when the lens of the camera is being rinsed, the aperture stop will hinder the rinse water flow, resulting in the inability to effectively clean the lens sur...
