Embodiment Construction

[0017] The invention will be described in detail below with reference to the accompanying drawings and examples.

[0018] Such as figure 1 As shown, a stereoscopic endoscope double optical path eyepiece adjustment device includes a first eyepiece assembly 1, a second eyepiece assembly 10 and a support base 2, wherein the support base 2 is provided with a cavity inside, the first eyepiece assembly 1 and the second eyepiece assembly The eyepiece assembly 10 is symmetrically placed in the cavity of the support seat 1, the first eyepiece assembly 1 and the second eyepiece assembly 10 have the same structure, and both include an eyepiece 5, an eyepiece barrel 4 and an eyepiece barrel adjustment sleeve 3, as image 3 As shown, the eyepiece 5 is placed in the eyepiece barrel 4, and the eyepiece barrel 4 and the eyepiece barrel adjustment sleeve 3 are connected by thread, which is used to connect the eyepiece barrel and the support seat, and adjust the relative position of the image t...

Abstract

The invention creatively discloses a stereoscopic endoscope dual-optical-path eyepiece adjusting device, which comprises eyepiece assemblies and a support base. The support base is internally provided with a cavity; the two groups of eyepiece assemblies are symmetrically arranged in the cavity of the support base; the top portion of the support base is provided with a groove; jackscrew holes are arranged in the connection place of the bottom portion of the groove and the side wall of the groove; and the two sides of the support base are symmetrically provided with jackscrew holes. Each eyepiece assembly comprises an eyepiece, an eyepiece tube and an eyepiece tube adjusting sleeve, wherein the eyepiece is arranged in the eyepiece tube, and the eyepiece tube and the eyepiece tube adjusting sleeve are connected in a threaded manner. According to the endoscope dual-optical-path eyepiece adjusting device, the groove of the support base as well as the two sides of the support base are symmetrically provided with the jackscrew holes, which are corresponding to the eyepiece assemblies respectively, so that more flexible adjustment of the eyepiece tube adjusting sleeve in each eyepiece assembly can be realized, the adjustment direction is clear, a user is allowed to adjust the light path more easily, the centre of each eyepiece lens is allowed to reach a coaxial state with the center of the light path, and images with relatively ideal definition can be obtained.

Description

technical field [0001] The invention belongs to the field of endoscopes, and in particular relates to a dual-light-path eyepiece adjustment device for a three-dimensional endoscope. Background technique [0002] 3D stereo endoscope mainly has two types of monocular channel and binocular channel. The binocular channel 3D stereo endoscope has two sets of optical paths inside. In order to have a better three-dimensional image display in the later stage, 3D stereo endoscope is required. The two sets of images of the speculum are completely overlapped. The eyepieces are very sensitive and precise parts in the two sets of optical paths. Very small adjustments will have a great impact on the images, and because the two sets of optical paths are often crowded when designing , the space for adjustment is very limited. Contents of the invention [0003] In view of this, the present invention aims to propose a stereoscopic endoscope dual optical path eyepiece adjustment device to so...
