Abstract

The utility model provides a self-cleaning type endoscope and relates to medical instruments. An annular washing head (3) and an annular liquid absorption head (4) are arranged at the edge of the outer side of an annular lens of an object lens head (1). Washing holes (5) and liquid absorption holes (6) are formed in the annular wall, close to the inner side, of the washing head (3) and the annular wall, close to the inner side, of the liquid absorption head (4). The liquid absorption head (4) is located at the inner side of the washing head (3). A washing pipe (7) connected with a washing device providing cleanout fluid and a liquid absorption pipe (8) used for absorbing liquid from the lens head are arranged in the wall of a lens cone (2). One end of the washing pipe (7) is communicated with the washing head (3) and the other end of the washing pipe (7) extends out of the non-object-lens end of the lens cone (2) and is provided with a switch valve (9). One end of the liquid absorption pipe (8) is communicated with the liquid absorption head (4) and the other end of the liquid absorption pipe (8) extends out of the non-object-lens end of the lens cone and is connected with a liquid absorption ball (10). An object lens is kept clear at any time through washing, washing liquid on the lens head can be rapidly absorbed, the distorted vision caused by liquid remaining on an ocular head is avoided, and therefore the imaging effect is prevented from being influenced.

Description

One self-cleaning endoscope

Technical field

This utility model relates to medical apparatus and instruments, is specifically related to a kind of endoscope with self-cleaning camera lens.

Background technology

Using in the process of endoscope, objective of endoscope head stretches into after check point, often smudgy due to the dip-dye of body fluid etc., and has influence on observing effect.

Summary of the invention

Technical problem to be solved in the utility model is: for the problems referred to above, provide a kind of self-cleaning endoscope.

Technical solution of the present utility model is: it comprises composition lens and lens barrel, described object lens headring eyeglass outer ledge is provided with the syringe pipe and the imbibition head that are annular, on the ring wall of syringe pipe and imbibition head rest inner side, be respectively equipped with flushing hole and imbibing hole, imbibition head is positioned at syringe pipe inner side, in the wall of described lens barrel, be provided with for the syringe pipe that provides the flusher of cleanout fluid to be connected with for the pipette from camera lens imbibition, syringe pipe one end is communicated with syringe pipe, the other end stretches out and is provided with controlled valve in the non-objective end of lens barrel, pipette one end is communicated with imbibition head, the other end stretches out and is connected with a Liquid absorption ball in the non-objective end of lens barrel.

Technique effect of the present utility model is: it have advantages of simple in structure, cost is low and easy to use, can make object lens keep clear by flushing at any time, and can absorb fast the flushing liquor at camera lens place, prevent that ocular head debris from making to look thing deformation, affects imaging effect.
