Abstract
The invention provides a front end structure of a three-dimensional endoscope. The front end structure comprises a fixing plate, an optical axis inner pipe, an inner pipe support and an outer pipe. The fixing pipe can be closely embedded in the front end of the outer pipe. An optical axis hole is formed in each of two sides of the fixing plate and tangent with the edge of the fixing plate. An opening is formed in each of tangent parts of the optical axis holes and the fixing plate. The fixing plate is further provided with two optical fiber holes which are in crescent shapes and in two sides of a center connecting line of the optical axis holes. The inner pipe support comprises two supporting holes. A distance between centers of the supporting holes is equal to that of the optical axis holes. The front end structure has the advantages that the distance between two optical axes in the three-dimensional endoscope is a maximum, and a better three-dimensional effect is guaranteed in the case of remote observation. With the inner pipe support, stability of the front end structure is ensured, and enough space is provided for the optical fiber to pass.
Description
Technical field
The invention belongs in solid peeps field of medical, especially relates to a kind of front-end architecture of stereo endoscope.
Background technology
The observation of stereo-picture is the object in sight line to be observed by two eyes left eyes and right eye simultaneously.By the image of left eye and the viewed diverse location of right eye.Through brain, just there is three-dimensional perception effect again.Wanting to reach good effect has relatively high expectations to two eyes observed ranges.
At medical field, the distance of stereo endoscope front end optical axis is equivalent to observe the distance between two of people.When doing the observation of the operation such as abdominal cavity, because the cavity in abdominal cavity is larger, when observation intraperitoneal organizing slightly a little further, if distance is less between optical axis, imaging third dimension is not high, affects observation effect.Therefore in the middle of the limited diameter of stereo endoscope mirror pipe front end, how to guarantee between two-way optical axis in ultimate range, be the problem that those skilled in the art need to solve.How stereo endoscope keeps the assemble stable of good luminous flux and maintenance front end inner tube simultaneously, is all to need at present the problem of solution.
Summary of the invention
The problem that the invention will solve is to provide a kind of front-end architecture of stereo endoscope, can solve the optical axis ultimate range design problem that current stereo endoscope field exists, and the problem of luminous flux and assemble stable.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is:
A kind of front-end architecture of stereo endoscope is provided, and described front-end architecture comprises fixing head, optical axis inner tube, interior pipe holder and outer tube; Described fixing head can closely be embedded in described outer tube front end, and described fixing head the right and left respectively has an optical axis hole tangent with its edge; Described fixing head also comprises two optic fibre holes, lays respectively at circle center line connecting both sides, described two optical axis holes; Described interior pipe holder the right and left respectively has a supported hole tangent with its edge.
Wherein, described two optical axis holes and the tangent part of fixing head respectively have an opening.
Wherein, described optic fibre hole is crescent.
Wherein, described interior pipe holder also comprises two grooves, lays respectively at described two supported hole circle center line connecting both sides.
Wherein, described two supported holes and the tangent part of interior pipe holder respectively have an opening.
Wherein, the distance between described two supported hole centers of circle equals described two optical axis hole circles distance in the heart.
Advantage and good effect that the invention has are: at conventional stereo endoscope distal end, increased fixing head and interior pipe holder.Optical axis inner tube can closely embed in the optical axis hole of fixing head, add that the tangent part of optical axis hole and fixing head is open state, just guaranteed at outer tube diameter fixedly in the situation that, the distance of center circle of two optical axis inner tubes is from farthest, guaranteed that two-way optical axis is in maximum distance, can produce best stereoeffect to remote observation.The tangent part of optical axis hole and fixing head is set to open state and is also more convenient for processing and having saved material in addition.
Meniscate optic fibre hole has farthest utilized the remaining space of fixing head, has guaranteed to insert the highlight flux of optical fiber.
Interior pipe holder gives optical axis inner tube by supported hole and supports, and guarantees the stable of the whole light path of front end, keeps ultimate range to play assistance positioning action to optical axis inner tube simultaneously.Two grooves of interior pipe holder also can provide support for the optical fiber penetrating, and avoid optical fiber because the soft central region sinking producing.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the invention is elaborated.
During assembling, first two optical axis inner tube front ends are embedded respectively in two supported holes of interior pipe holder, and will after interior pipe holder, move to the medium position of optical axis inner tube, then two optical axis inner tube front ends are embedded respectively in two optical axis holes of fixing head.After fixing, from the rear end of optical axis inner tube, penetrate optical fiber, after the groove by interior pipe holder, arrive the optic fibre hole of fixing head.Finally outer tube is inserted in from the rear end of optical axis inner tube, moves forward to after optical axis inner tube front end, fixing head is embedded in outer tube, so far completed the assembling process of a whole set of front-end architecture.
Above the invention embodiment is had been described in detail, but described content is only the preferred embodiment of the invention, can not be considered to for limiting the practical range of the invention.All equalization variations of doing according to the invention application range and improvement etc., within all should still belonging to the patent covering scope of the invention.
