Abstract
The present invention relates to an oblique photograph moving device of an X-ray machine, which is composed of an X-ray bulb tube (1), a front mounted tension diagonal (2), an upright post (3), a compressor (4), a film jacket (5) in a film system, a bed plate (6), a film system (7), an image intensifier (8) and a rotary shaft (9). The present invention is characterized in that the rotary shaft (9) is divided into an upper rotary shaft and a lower rotary shaft; the lower end of the front mounted tension diagonal (2) is hinged at the upper surface of the film system (7), and the upper end of the front mounted tension diagonal (2) is hinged with the upper rotary shaft; the H1 distance between a hinged joint at the lower end of the front mounted tension diagonal (2) and the film jacket (5) of the film system is equal to the H2 distance between a shaft line of the upper rotary shaft and the shaft line of the lower rotary shaft; the upper rotary shaft and the lower rotary shaft can transmit the movement by 3 identical gear wheels (the middle gear wheel is an idler gear wheel) so that the rotary directions of the rotary angles of the upper rotary shaft and the lower rotary shaft are completely identical. Thus, a thing that the center of the X-rays from bulb tube can aim at a midpoint of the film all the time in the process of the oblique photograph is ensured. Consequently, the compressor is fixed on the tension diagonal to accurately press on the examined position of human body.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, be specifically related to the mechanical driving device of X line machine oblique photograph.
Background technology
At present, X line machine is all developing to the direction with oblique photograph function, and promptly when oblique photograph, the ray of bulb is not perpendicular to bed board and image system (comprising tested patient), but an angle is arranged.The essential condition of oblique photograph is: bulb will guarantee that the X wire harness that passes tested position should impinge upon on the input screen of film and image amplifier exactly when deflection angle, with the film making accurately that realizes the human body of expectation is implemented real-time perspective and obtained.Realize the mechanical drive mode of this photography, mainly contain two big classes at present in the world: first class: the column that can tilt is arranged, and bulb and its are connected.When tilting, the column of the bulb that is being connected is done the swing arm campaign, and the X wire harness that bulb sends passes tested position and is radiated on film and the image amplifier; Second largest class: A, not tiltable of column only can translations, and column and bulb are hinged, and bulb is hinged by a telescopic connecting rod and image system, and connecting rod is positioned at the front of column.The precondition of this structure is: the X line receiving plane of image system must and brace lower end hinge on a horizontal plane; What B was different with A is that connecting rod is positioned at the back of column.
The defective that above-mentioned known technology exists is: first class: set up a cover driving device and a positioning detecting circuit for the skew of column (bulb) specially, make structure become complicated, and weight is corresponding also to be increased, and outward appearance also seems too fat to move in addition, and the swing speed of column is low; Second largest apoplexy due to endogenous wind, A, since brace be positioned at the front of column and lower link point must and film in one plane, so film system is had a requirement, be that lateral dimension can not be too big, this makes the horizontal function limitation of film system, otherwise the following hinge position of brace and stud are moved after all needing laterally, make the lateral dimension (width) of complete machine strengthen; Though B, brace are positioned at the pattern of column back the horizontal lattice function of film system is not restricted, fatal shortcoming is: compressor can not be pressed in tested position synchronously with beam, and film making is affected to make enforcement have an X-rayed and obtain accurately in real time.
Summary of the invention
The objective of the invention is, in order to overcome the defective that known technology exists, design and a kind ofly can support the horizontal lattice pattern of film, can guarantee the oblique photograph telecontrol equipment of the New X line machine that beam and compressor are in real time synchronous again, make it simple in structure, in light weight, the reliability height, applied range, outward appearance is good.
The oblique photograph telecontrol equipment of X line machine of the present invention is by comprising X ray tube (1), preposition brace (2), column (3), compressor (4), the sheet folder (5) of film system, bed board (6), film system (7), image amplifier (8), rotating shaft (9) constitutes, its main points are, rotating shaft (9) is divided into rotating shaft (9a) and lower rotary shaft (9b), and preposition brace (2) lower end is hinged on film system (7) upper surface, the upper end is hinged with last rotating shaft (9a), and X ray tube (1) is connected with lower rotary shaft (9b) end.
Distance H between the sheet folder (5) of above-mentioned preposition brace (2) lower end pin joint and film system
1Equal between rotating shaft (9a) and lower rotary shaft (9b) apart from H
2By 3 identical gears (13), (14), (15) transmitting movement, wherein, gear (14) is an idle pulley between last rotating shaft (9a) and the lower rotary shaft (9b).
The present invention compared with the prior art, its significant advantage and effect are: because the present invention has changed preposition brace lower end and the hinged position of film system in the prior art, thereby kept the horizontal lattice pattern of support film system, do not needed to strengthen the lateral dimension of complete machine again; The present invention changes the known technology shaft into upper and lower rotating shaft again in addition, between its upper and lower shaft axis apart from H
2Just equal between the sheet folder of brace lower end hinge and film system apart from H
1, to move by 3 identical gear transmission again between the upper and lower rotating shaft simultaneously, one of them is an idle pulley, makes the two corner like this, turns to identically, has guaranteed that bulb X ray center when oblique photograph, aims at the mid point of film all the time.Compressor is fixed on the brace, can accurately be pressed on the tested position of human body, guarantees that beam and compressor are synchronous in real time.
