Oral cavity tissue low-loss type oral endoscopeTechnical Field
The invention relates to the technical field of oral endoscopes, in particular to a low-loss oral endoscope for oral tissues.
Background
When the endoscope is placed on the operation table halfway, the handle, the connecting catheter and the data wire are required to be kept in a connecting state to maintain the equipment standby. At the moment, the endoscope insertion part horizontally contacts with the table surface, and disinfectant, body fluid or environmental pollutants possibly remain on the table surface, and secondary pollution is easily caused by direct contact with the surface of the insertion part;
in the prior art, as the indexing suspension frame proposed by the patent CN221904029U, the multi-angle positioning is realized by matching the rotating shaft with the indexing seat, so that a plurality of endoscopes are allowed to be suspended at the same time, and the occupation of vertical space is reduced. However, this solution allows to achieve a vertical suspension avoiding the problem of contaminating the endoscope body in a horizontal position, but still suffers from the following drawbacks:
The chuck design of the indexing suspension frame enables the endoscope to take the handle as a suspension pivot, and the insertion part naturally sags. When the handle is hung in a working state, the guide wire and the guide pipe still form an acute angle to bend at the joint due to the action of gravity, and the cable insulating layer is easy to crack or the sealing of the guide pipe joint is easy to damage after long-term use.
Accordingly, the present application provides a low-loss oral tissue type oral endoscope.
