Embodiment Construction

[0012] Such as figure 1 As shown, the present invention includes an insertion part and an objective lens observation window located on the side of the front end of the insertion part. Among them, there are two objective observation windows.

[0013] The working process of this example: After inserting the insertion part into the human body, since the objective lens observation window is set on the front side of the insertion part, the distance between the two objective lens observation windows is no longer limited. Observe the size of the target volume to be observed The distance has a better observation effect. The effect of dealing with some large targets and some distant targets in laparoscopy is particularly obvious.

[0014] An embodiment of the present invention has been described in detail above, but the content is only a preferred embodiment of the present invention, and cannot be considered as limiting the scope of implementation of the present invention. All equal chan...

Abstract

The invention provides a lateral observation type stereo endoscope end structure which comprises an insert part and two objective lens observation windows located on the lateral side of the front end of the insert part. Compared with a traditional structure with an observation window located on the end face of the front end, the lateral observation type stereo endoscope end structure has the advantage that the distance between the two windows of the structure is not limited by the size and space of the end face, and therefore different operation and inspection requirements are met.

Description

Technical field [0001] The invention belongs to the field of stereo endoscopes, and in particular relates to a side-view stereo endoscope end structure. Background technique [0002] The observation of the stereo image is to observe the objects in the line of sight simultaneously through the left and right eyes of two eyes. Images of different positions observed by the left and right eyes. After passing through the brain, a three-dimensional look and feel will appear. To achieve better results, the observation distance of the two eyes is required to be higher. If the distance is too far, the three-dimensional effect becomes less obvious and the three-dimensional effect is not prominent. When it is too close, it makes the observed image messy, which easily makes people feel dizzy and even unable to perform effective image recognition. [0003] The observation sites of the usual stereoscopic endoscopes are all on the front of the front end of the insertion portion, which is 0-30 ...
