Abstract

The utility model belongs to a stereoscopic film-observing lamp. The usual used film-observing lamp is generally plane. The film can make the three-dimensional object change into an overlapping screen sheet, so that user is difficult to observe the body shape of the screened object and user can not identify the hierarchy relationship of the front part and the rear part. The utility model has the advantages of simple structure, convenient operation, clear and stereoscopic image, and high resolution. The stereoscopic film-observing lamp is good for clinical diagnosis. The stereoscopic film-observing lamp can also be used as a plane film-observing lamp. The stereoscopic film-observing lamp is especially suitable for the clinical diagnosis for bone surgery disease and fineness pathological changes.

Description

Stereoscopic film-observing lamp

Normally used viewbox generally is the plane, and the X-ray photograph of being seen is a sheet of planar transparency.This slice, thin piece is that three-dimensional object has been become overlapping transparency, thereby is difficult to find out and also can divide forward and backward hierarchical relationship by the concrete form of the object of taking the photograph.So in clinical diagnosis, particularly, easily cause mistaken diagnosis owing to judge inaccurate to excessive overlapping part and the difficult position of taking lateral projection to some disease.

The purpose of this utility model be make a kind of simple in structure, easy to use and help clinical diagnosis, particularly to a kind of stereo viewer of Orthopeadic Surgery disease clinical diagnosis.This stereo viewer that comprises casing, daylight lamp, sheet folder is characterized in that by catoptron (1), slide glass door (2), and locator card (10) and flexible wheelwork (3) and black draw curtain compositions such as (5).Said catoptron (1) is to constitute 60 degree lordosis angles (8) by two leaf eyeglasses to be fixed in the casing (4), its function is that the binocular parallax stereo image principle of using common people realizes, promptly same object is respectively clapped 1 X-ray sheet with the position of commissarial two eyes of X-ray, with the beam split means two slice, thin pieces that this is equivalent to be clapped people's right and left eyes position are sent into right left eye respectively again, promptly constitute stereoscopic vision.This and plane viewbox compare, and the information of image has increased by one times, and its sharpness and resolution have significantly improved.Said slide glass door (2) is by framework (11), opal glass (13) and handle (9), small sheave compositions such as (12), its opal glass (13) is fixed in the framework (11), by the two ends up and down of catoptron one side one little handle (9) is housed respectively at framework (11), framework upper and lower side at its offside respectively is equipped with a small sheave, daylight lamp (6) is equipped with at the back side of slide glass door (2), because slide glass door (2) can be movable, daylight lamp (6) is contained in slide glass door (2) back and helps the even of light.Be applicable to various operating positions.Said slide glass door (2) is two, the side that two slide glass doors (2) are equipped with handle (9) is fixed in the casing (4) with the indent angles (7) that the other both sides formation 60 of catoptron (1) is spent respectively, at the upper and lower side of two slide glass doors (2) with respect to the other both sides that handle (9) is arranged, be fixed with an end of flexible wheelwork (14), the other end of flexible wheelwork (3) is fixed on the casing (4).Because flexible wheelwork is housed, thereby this stereo viewer also can when using as the plane viewbox, draw little handle (9) forward as common planar viewbox usefulness, and two slide glass doors (2) can move forward, and move to two slide glass door (2) and start-stops.When using stereo viewer, can be with little handle (9) toward pusher, be pushed into and become 60 to spend the indent angles and promptly end with the opposite side of catoptron (1).This moment, flexible wheelwork (3) played crucial the work.Said flexible wheelwork (3) is made up of 4 pages of hinges (14) (15) (16) (a 17) and extension spring (19) etc., be to connect between four pages of hinges (14) (15) (16) (17) by three pivot pins (18) (20) (21), hinge (14) is to be fixed on the slide glass door (2), and hinge (17) is fixed on the case.One end of said extension spring (19) is to be fixed on hinge (16) to locate near pivot pin (20), and the other end of extension spring (19) is fixed on the casing (4).Said locator card (10) is triangular in shape, is fixed on the upper end of slide glass door (11), and the effect of locator card (10) is that two X-ray sheets of control make two position consistency when two slide glass doors (2) are reflected in the catoptron.In the front of casing two black that can spur are housed and draw curtain, when seeing Stereogram, two black are drawn the curtain pull-up after, two black leave certain distance in the middle of drawing curtain, this has just constituted one and has watched window, and it is to concentrate sight that the purpose that black draws curtain is set, to avoid the interference of extraneous high light.When this viewbox uses as the plane viewbox, then black is drawn curtain to move both sides respectively to, slide glass door (2) is pulled out get final product.
