Description
This utility model belongs to medical corollary equipment technical field, specially refers to a kind of location structure of X ray simulated positioner.Be applicable to tumour patient is carried out the location before the radiotherapy and carries out the special surgical operation of tumor intervention therapeutic.
At present, the X ray simulated positioner is an indispensable corollary equipment on the theratron.Because radiocurable purpose be to greatest extent kill cancer cell, protect cell to greatest extent; position fixing process requires quick, accurate so; only need produce the X ray at several milliamperes of zero points during perspective, strengthen system, just clearly demonstrate the position of tumor by polychrome.Reach accurate positioning, just require the location to wait errors of centration the smaller the better.In order to solve the problems of the technologies described above, develop a kind of location structure of X ray simulated positioner, the positioning accuracy of this simulated positioner is reached≤R1.5mm, to meet figure person company standard.
The purpose of this utility model: in order to solve the problems of the technologies described above, and provide a kind of location structure of X ray simulated positioner.This positioning accuracy that simulates localization machine reaches≤R1.5mm, to meet national company standard.It mainly is made of parts such as mainframe, fluoroscopy system telecontrol equipment, beam-defining clipper system authority, diagnosis bed surface motion and bed bodies.Wherein the bed body is made revolution motion with the axle center around ray, its bearing is to be fixed on mainframe and the common base of diagnostic bed body, and base is to be fixed on the ground, because base is a machined piece, therefore, can guarantee the relative position accurate positioning of mainframe and diagnostic bed body, motion has guaranteed center precision such as location freely.In order to reach the positioning accuracy standard, except that requiring location structure technological measure assurance reasonable in design, strict, also require electric-control system to cooperate synchronously.Have that location structure is reasonable in design, compact conformation, accurate positioning, rotation are steadily reliable, it is eye-catching to show, sports safety, advantage such as easy to maintenance and easy to implement.
To achieve these goals, invention scheme of the present utility model is: in Figure of description, Fig. 1 provides the location structure sketch map of this simulated positioner, and it mainly is made of parts such as mainframe (1), fluoroscopy system telecontrol equipment (2), beam-defining clipper system authority (3), diagnosis bed surface motion (4) and bed bodies (5).Its each several part routing motion process: the rotation of the big support arm (1-5) of mainframe (1) is to pass through worm gear, worm reducer (1-3) by pinwheel pendulum line reducer (1-1), drives big support arm (1-5) rotation by sprocket wheel (1-4).And control its rotary speed by variable-frequency governor (1-2), reaching rotation steadily, the low and speed of noise is adjustable continuously etc.The lifting of the image amplifier (2-5) in the fluoroscopy system telecontrol equipment (2), about, seesaw, by pinwheel pendulum line reducer (2-1), drive screw mandrel (2-3) by gear or belt pulley and drive its motion by screw.For prevent big support arm (1-5) at the volley image amplifier (2-5) rock, designed guide rail and eccentric guide wheel (2-2) and oilite bushing (2-4), make its motion steadily, do not rock, can adjust, can also self-zeroing.Photograph in the beam-defining clipper system authority (3) is to be emission source by the TQ-7X ray tube (3-1) that emission high energy weighs with perspective, by the point source emitted light beams, impinges upon on the human body accurately through the position of reflecting mirror (3-2) with ray.Taking a picture with the rotation of having an X-rayed head is to drive gear wheel (3-8) by the nylon gear on the servomotor (3-3) to be rotated.The bearing (3-4) that its rotation is used is non-standard design voluntarily, makes the head rotation steadily, noiselessness, and the error of rotation is little.The agent that ray passes through heavily is by the folding decision of plumbous door (3-5), and the plumbous door of symmetry (3-5) mobile is the driving by well word line motion motor (3-6), and plumbous door (3-5) is parked in accurately on the position.The projection of well word line (3-7) shift position also is the zone of patient's focus, and its motion principle is identical with plumbous door (3-5) motion.The bed surface (4-1) of diagnosis bed surface motion (4) is to carry that patient does laterally, the supporter of lengthwise movement, can rotation 180 °, and whole diagnostic bed also can be done ± 90 ° of motions of revolution, and it makes ray aligning patient's focus.Its is done laterally and lengthwise movement is to drive nylon gear, tooth bar (4-3) by motor (4-2), and it move by guide rail, guide wheel (4-4) correcting, bed surface (4-1) is moved do not depart from, noiselessness, the position that stops be accurate.There is electromagnetic brake (4-5) to suck after motion stops, makes bed surface (4-1) no longer move, reserve the position and no longer depart from, make it accurate positioning.The lifting of bed body (5) is to make the pinwheel cycloidal generator (5-6) of revolution by worm gear, worm reducer (5-1) by diagnostic bed, drive two cranks (5-2) motion, slow down bed surface (4-1) picking-up by lifting linking member (5-7), the height of bed surface (4-1) lifting equals 4 times of crank (5-2) length.Whole diagnostic bed also can be made revolution motion around the axle center of ray, its bearing (5-4) is fixed on mainframe (1) and the common base of diagnostic bed (5-5), and base (5-5) is to be fixed on the ground, because base (5-5) is a machined piece, therefore, can guarantee the relative position accurate positioning of mainframe (1) and diagnostic bed, motion has guaranteed center precision such as location freely.About architectural feature of the present utility model and embodiment, in the Figure of description explanation, be illustrated.
Advantage of the present utility model:
Reasonable in design and the compact conformation of the location structure of this simulated positioner, wherein the rotation of the big support arm (1-5) of mainframe (1) is to pass through worm gear, worm screw (1-3) decelerator by pinwheel pendulum line reducer (1-1), drives big support arm (1-5) rotation by sprocket wheel (1-4).And control its rotary speed by variable-frequency governor (1-2), reaching rotation steadily, the low and speed of noise is adjustable continuously etc.For prevent big support arm (1-5) at the volley image amplifier (2-5) rock, designed guide wheel and eccentric guide wheel (2-2) and oilite bushing (2-4), make its motion steadily, do not rock, can adjust, can also self-zeroing.The bed surface of diagnostic bed (4-1) is to carry that patient does laterally, the supporter of lengthwise movement, can rotation 180 °, and whole diagnostic bed also can be done ± 90 ° of motions of revolution.It makes ray aim at patient's focus.It is done laterally and lengthwise movement is to drive nylon gear, tooth bar (4-3) by motor (4-2), and it moves by guide rail, guide wheel (4-4) correcting.The lifting of bed body (5) is to make the pinwheel swing motor (5-6) of revolution by worm gear, worm reducer (5-1) by diagnostic bed, drive two cranks (5-2) motion, by lifting linking member (5-7) bed surface (4-1) is held up, the height of bed surface (4-1) lifting equals 4 times of crank (5-2) length.Because bearing (5-4) is to be fixed on mainframe (1) and the common base of diagnostic bed (5-5), and base (5-5) is to be fixed on the ground, therefore, can guarantee the relative position accurate positioning of mainframe (1) diagnostic bed, has guaranteed center precision such as location.The positioning accuracy of this simulated positioner is reached≤R1.5mm, to meet national company standard.Have that location structure is reasonable in design, compact conformation, accurate positioning, rotation are steadily reliable, it is eye-catching to show, sports safety, advantage such as easy to maintenance and easy to implement.
