Background technology
Medical X-ray tube sends X-ray beam, after irradiated human body, forms the radioscopic image of illuminated human body on film or digital image plate.Owing in X-ray beam, the wavelength of X ray, by certain limit distribution, is decayed after longer wavelengths of X-ray transparent human body relatively big, this partial x-ray makes radioscopic image imaging unintelligible, reduces the resolution of image, have impact on the diagnosis of smaller part position.In order to solve this problem, improve the resolution of radioscopic image, it is necessary to by longer wavelengths of X-ray shield, make the shorter X-radiation of wavelength to film or digital image plate.Optical filter is to make with relatively thin copper coin or aluminium sheet, the filter plate of different-thickness is placed on X-ray tube and sends the window of X ray and shone between human body, to shield the X ray of different wave length.
Owing to beam-defining clipper is X-ray beam to extraradial unique passage, in order to easy to operate, being typically all by filter sheet integrated in beam-defining clipper, as an auxiliary equipment of beam-defining clipper, optical filter is in the lower section of beam-defining clipper housing, the both sides of beam-defining clipper window arrange two slots, being inserted in slot by the optical filter of different-thickness as required, its shortcoming is separate due to filter plate and beam-defining clipper, it is easy to cause optical filter to scratch, affecting picture quality, it is constant that operation also has more.
Summary of the invention
Separate with beam-defining clipper for the filter plate in X ray beam-defining clipper in prior art, scratch easily caused by optical filter, affecting the deficiencies such as picture quality, the technical problem to be solved in the present invention is to provide a kind of built-in guide tracked switching device of optical fiber of the X ray beam-defining clipper avoiding optical filter to damage.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
The built-in guide tracked switching device of optical fiber of one X ray beam-defining clipper of the present invention, is installed on beam-defining clipper enclosure interior base plate, has upper and lower two-layer guide rail, be respectively arranged in base plate both sides, and every layer of guide rail is all slidably placed one piece of filter plate.
The one end of the upper strata filter plate being positioned on the guide rail of upper strata passes sequentially through the first upper strata connecting rod and the second upper strata connecting rod is connected with upper strata handle；The one end of the lower floor's filter plate being positioned on lower floor's guide rail passes sequentially through first lower floor's connecting rod and second lower floor's connecting rod and is connected with lower floor handle；It is rotationally connected by connection axle between second upper strata connecting rod and second lower floor's connecting rod.
Described second upper strata connecting rod and second lower floor's connecting rod are bending structure, and the two is rotationally connected by connecting axle at bending part.
Described upper strata handle and lower floor's handle are arranged on beam-defining clipper hull outside.
The invention have the advantages that and advantage:
1. the present invention adopts built-in optical filter, makes optical filter by certain frame for movement, is placed on by optical filter inside beam-defining clipper, operator can pass through to be arranged on the handle of beam-defining clipper hull outside, selecting the optical filter of different-thickness, its advantage is that optical filter will not have damage, easy to operate.

Detailed description of the invention
Below in conjunction with Figure of description, the present invention is further elaborated.
As shown in Figures 1 to 3, the built-in guide tracked switching device of optical fiber of X ray beam-defining clipper of the present invention, it is installed on beam-defining clipper enclosure interior base plate, there is upper and lower two-layer guide rail, be respectively arranged in base plate both sides, every layer of guide rail is all placed one piece of filter plate.
As shown in Figure 2,3, the one end of the upper strata filter plate being positioned on the guide rail of upper strata passes sequentially through upper strata first and connects axle and the first upper strata connecting rod connection, first upper strata connecting rod connects axle by upper strata first and the second upper strata connecting rod connects, and upper strata handle is arranged on the second upper strata connecting rod；The one end of the lower floor's filter plate being positioned on lower floor's guide rail passes sequentially through lower floor first and connects axle and the connecting rod connection of the first lower floor, and first lower floor's connecting rod connects axle by lower floor first and second lower floor's connecting rod connects, and lower floor's handle is arranged on second lower floor's connecting rod.In the present embodiment, the second upper strata connecting rod and second lower floor's connecting rod are bending structure, and the two is rotationally connected by connecting axle at bending part.This connection axle supports the second upper strata connecting rod and second lower floor's connecting rod, stir upper strata handle, first upper strata connecting rod rotates centered by axle to connect, and drives the rotation of the second upper strata connecting rod to make upper multilayer filter move in the upper strata guide-track groove of two side rails by rotating of the first upper strata connecting rod；In like manner, stirring lower floor's handle, first lower floor's connecting rod rotates centered by axle to connect, and drives the rotation of second lower floor's connecting rod to make lower multilayer filter move in lower floor's guide-track groove of two side rails by rotating of first lower floor's connecting rod.Owing to being limited by space, the discrepancy in elevation of upper strata filter plate and lower floor's filter plate is 10mm.
Upper strata handle and lower floor's handle are arranged on beam-defining clipper hull outside.
The operation principle of the present invention is as follows:
Stir upper strata handle, drive the rotation of the second upper strata connecting rod to make upper multilayer filter move in the upper strata guide-track groove of two side rails by rotating of the first upper strata connecting rod, make upper strata filter plate shielding or do not shield X ray.Stir lower floor's handle, drive second lower floor's link rotatable to make lower multilayer filter move in lower floor's guide-track groove of two side rails by first lower floor's link rotatable, make lower floor's filter plate shielding or do not shield X ray.So go up multilayer filter and lower multilayer filter can form the optical filter of three kinds of different-thickness, namely upper strata, lower floor, upper strata+lower floor.To meet the needs of different application.
The present invention adopts built-in structure, makes optical filter by certain frame for movement, is placed on by optical filter inside beam-defining clipper, operator can pass through to be arranged on the handle of beam-defining clipper hull outside, selecting the optical filter of different-thickness, its advantage is that optical filter will not have damage, easy to operate.
