Abstract
The utility model relates to a one-off sub-primary endoscope which can be combined and dissembled with a sub endoscope changeable. The utility model is composed of a sub endoscope and a primary endoscope of a cecum casing, wherein, a lens and a light guiding layer are terminal parts of the optical system of the primary endoscope; the bottom of the light guiding layer is lower than the lens; and the objective lens of the primary endoscope and the light guiding layer of the light source are in high and low positions. With the utility model, the endoscope can be dissembled in split type; the sub endoscope can disinfect , can be changed or can be thrown away after used once; the endoscope is sealed; the focal length of the endoscope can be adjusted; and the utility model has characteristics of simple and reasonable design and low cost.
Description
Affiliated technical field
This utility model relates to a kind of disposable primary and secondary endoscope, especially can make up dismounting and change sub-mirror.
Background technology
Current endoscope class operating theater instruments mostly is integrative-structure, and promptly the imaging optical system of endoscope and light source optical fibers system (illumination) are as a whole.Make, dismantle maintenance, sterilization difficulty, the use cost height.Have a lot of inventions to design the disposable external-cover that is enclosed within the above-mentioned endoscope at present, purpose is an anti-cross infection, and a kind of object lens open-ended is arranged, and to expose endoscope lens and light source, does not realize aseptic isolation; Another kind of objective end seals with eyeglass, with the simple and easy cover of endoscope therein, but does not consider that the strong illumination light of endoscope can cause the optical diffraction of protection eyeglass to pollute, and has changed the objective lens optical system refractive index, has reduced degree of getting a clear view.
Summary of the invention
In order to overcome the integral structure of existing endoscope class operating theater instruments; its dismounting maintenance, sterilization difficulty; the use cost height; with deficiencies such as protective sleeve optical diffraction pollutions; this utility model provides a kind of disposable primary and secondary endoscope; the dismounting of this primary and secondary endoscope easily, no optical diffraction pollution, and can dismantle and abandon and change sub-mirror.
The technical scheme that its technical problem that solves this utility model adopts is: objective of endoscope opticator (female mirror) is the branch body structure with light source light guide (sub-mirror), sub-mirror is the cecum sleeve pipe, cecum seals with lens, optics of lens curvature is the terminal part of female endoscope objective lens optical system, can also can focus by clear transmission image, female mirror optical system is imperfect, can not use separately.Sub-mirror internal and external casing interlayer is made up of one deck optical waveguide layer, and the bottom surface is lower than lens, can transillumination the lighting source of female mirror, and effectively stop optical diffraction and pollute.
The beneficial effects of the utility model are, use this utility model and make the endoscope can the split dismounting, and sub-mirror is replaceable to be abandoned, sterilize, the thread seal adjustable focal length, and this structural design advantages of simple, cost is low.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified.
Fig. 1 is the structural map of disposable primary and secondary endoscope neutron mirror.
Fig. 2 is the structural map of female mirror in the disposable primary and secondary endoscope.
Screw thread, (10) light tight coating are regulated in (1) sub-mirror, (2) female mirror, (3) lens, (4) inner sleeve, (5) optical waveguide layer, (6) trocar sheath, (7) objective end, (8) light source optical waveguide layer, (9) among the figure.
The specific embodiment
In Fig. 1 and 2, disposable primary and secondary endoscope is made up of the telescopic sub-mirror of cecum (1) and female mirror (2), lens (3) and optical waveguide layer (5) are the terminal parts of female endoscope objective lens optical system, and optical waveguide layer (5) bottom surface is lower than lens, and female endoscope objective lens end (7) becomes the high low platform shape with light source optical waveguide layer (8).
In Fig. 1, disposable primary and secondary endoscope neutron mirror (1) mantle cavity and female mirror (2) are complementary, sub-mirror (1) objective end is made up of inside and outside two-layer sleeve pipe, inner sleeve (4) is sealed to cecum by lens (3), the optical curvature of lens (3) is the terminal part of female endoscope objective lens optical system, can be by regulating screw thread (9) the adjusting definition and the visual field, visual angle.Inner sleeve (4) is sealed by optical waveguide layer (5) with trocar sheath (6) is middle, and (5) are the terminal parts of female endoscope objective lens illuminator, and optical waveguide layer (5) bottom surface is lower than lens can effectively stop the optical diffraction pollution.In order to increase the sectional area of optical waveguide layer (5), inner sleeve (4) can replace with light tight coating (10), promptly is coated with light tight coating in the optical waveguide layer (5).
In Fig. 2, female mirror (2) is the incomplete endoscope of optical system in the disposable primary and secondary endoscope, must cooperate and to use by regulating screw thread (9) with sub-mirror (1), its objective end (7) becomes the high low platform shape with light source optical waveguide layer (8), objective end (7) external diameter and interior pipe (4) internal diameter are sealed and matched, and prevent light leakage diffraction.
Claims (5)
1. disposable primary and secondary endoscope, it is characterized in that: form by the telescopic sub-mirror of cecum (1) and female mirror (2), lens (3) and optical waveguide layer (5) are the terminal parts of female endoscope objective lens optical system, optical waveguide layer (5) bottom surface is lower than lens, and female endoscope objective lens end (7) becomes the high low platform shape with light source optical waveguide layer (8).
2. disposable primary and secondary endoscope according to claim 1, it is characterized in that: sub-mirror (1) is the cecum sleeve pipe, objective end is made up of inside and outside two-layer sleeve pipe, and inner sleeve (4) is sealed to cecum by lens (3), and inner sleeve (4) is sealed by optical waveguide layer (5) with trocar sheath (6) is middle.
