Abstract
The invention discloses a dual-lens distal end part structure for an endoscope. The dual-lens distal end part structure is characterized by comprising a distal end and an instrument channel wherein a first objective lens and a second objective lens are respectively arranged on the front surface and the side surface of the distal end; the first objective lens is provided with a 0-degree direct view objective lens; first LED light sources are arranged on the two sides of the 0-degree direct view objective lens; the instrument channel is connected with the 0-degree direct view objective lens; the second objective lens is provided with a 90-degree side view objective lens; second LED light sources are connected with the two sides of the 90-degree side view objective lens. According to the dual-lens distal end part structure for the endoscope, the 0-degree direct view objective lens and the 90-degree side view objective lens are arranged at the distal end of the endoscope, so that the two objective lenses can be used for viewing or shooting simultaneously; the visual angle range is enlarged; the using requirement is met.
Description
Technical field
The present invention relates to endoscopic technique field, relate to a kind of first end construction of twin-lens of endoscope in particular.
Background technology
Endoscope lens is in the market divided into direct-view 0 °, look side ways 15 °, stravismus 30 °, stravismus 45 ° etc. and side-looking 90 °.Single lens angular field of view is maximum can not more than 120 °, because along with angular field of view strengthens, image just there will be spherical deformation, traditional solution needs to change camera lens according to use to reach application target, but the configuration design of endoscope needs higher, because environment for use needs must be designed to seal completely and have water proofing property, change the input that camera lens not only increases cost simultaneously, and waste more treatment time.
Therefore how to provide that a kind of to increase the first end construction that angular field of view meets the endoscope of instructions for use be the problem that those skilled in the art need solution badly.
Summary of the invention
In view of this, the invention provides and a kind ofly increase the first end construction that angular field of view meets the endoscope of instructions for use.
To achieve these goals, the invention provides following technical scheme:
The first end construction of twin-lens of endoscope, comprising: first termination; The front of described first termination and side are respectively arranged with the first composition lens and the second composition lens; Described first composition lens is provided with 0 ° of direct-view object lens; The both sides of described 0 ° of direct-view object lens are provided with the first LED light source; The instrument channel be connected with described 0 ° of direct-view object lens; Described second composition lens is provided with 90 ° of side-looking object lens; The both sides of described 90 ° of side-looking object lens are connected with the second LED light source.
Preferably, in the first end construction of the twin-lens of above-mentioned a kind of endoscope, in described first termination, software control system is provided with.
Preferably, in the first end construction of the twin-lens of above-mentioned a kind of endoscope, described first LED light source has two, and adopts the connected mode of welding to be symmetrically distributed in the both sides of described 0 ° of direct-view object lens.
Preferably, in the first end construction of the twin-lens of above-mentioned a kind of endoscope, described second LED light source has two, and adopts the connected mode of welding to be symmetrically distributed in the both sides of described 90 ° of side-looking object lens.
The present invention, by arranging 0 ° of direct-view object lens and 90 ° of side-looking object lens in the first termination of endoscope, can use by two object lens simultaneously, watches or shoot with video-corder, increase angular field of view and meet instructions for use.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to the accompanying drawing provided.
Fig. 1 is structural representation of the present invention.
In FIG:
1 for be the first composition lens, 3 be the second composition lens, 21 to be 0 ° of direct-view object lens, 22 be in first termination, 2 first LED light source, 23 be the second LED light source for instrument channel, 31 is 90 ° of side-looking object lens, 32.
