Embodiment 1 cylinder kayser integral type radiotherapy body location hollow fixed mount

With reference to Fig. 1, this utility model is made up of cylinder kayser integral type fixed mount and Tenon integral type body film two parts.Cylinder kayser integral type fixed mount by fixing cell wall 19, fixed base plate 25, base plate slope 34, treatment tank 35, base plate locating hole 37, base plate hollow bulb 38, base plate meet locating hole 39 and 10 tool column type locking structure 109 and jointly form.The agent structure of fixed mount is one piece of rectangular fixed base plate 25, and central hollow out is designed with base plate hollow bulb 38, plays the effect reducing ray attenuation; The long edge in both sides is respectively connected with 5 tool column type locking structures 109, between be connected to form two fixing cell walls 19 and four cylinder briquettings 58 of strip; Article two, the fixing cell wall 19 of strip and the treatment tank 35 of base plate formation " U " shape; Fixed base plate 25 both sides shorter edge is respectively connected with base plate slope 34; Fixed base plate 25 upper shed near base plate slope 34 has base plate locating hole 37 and bottom plate combined locating hole 39, plays fixing spacing fixed base plate, fixed base plate is connected with therapeutic bed.

With reference to Fig. 2, tenon integral type body filmjointly be made up of low temperature thermo-plastic planking 1, film bar 2, the film fourth of the twelve Earthly Branches 3, film bar Positioning bean 4, film bar handle 5 and film interspace 6.Agent structure is a rectangular low temperature thermo-plastic planking 1, and its two longer edges are connected with the long limit of two film bars 2; The minor face of film bar 2 flushes with the minor face of low temperature thermo-plastic planking 1, leaves film interspace 6 between the two; Two ends, the intermediate distribution on every root film bar 2 surface have three film fourths of the twelve Earthly Branches 3 running through holostrome, are placed on the upper fixing tenon 20 of supporting fixed body frame (base plate) mutually for conformal; Between three film fourths of the twelve Earthly Branches 3, equidistant design has two film bar Positioning beans 4, and it can be located recessed 33 with the pressing plate on pressing plate 24 and coincide for fastening film bar 2; The marginal center that film bar 2 is connected with low temperature thermo-plastic planking 1 is designed with film bar and shakes hands 5, is convenient to installation and the dismounting of the parts such as body film and supporting base plate.

With reference to Fig. 3 and 4, column type locking structure 109by fixing cell wall 19, fixing tenon 20, fixed base plate 25, tenon stricture of vagina 27, compress stricture of vagina 57, cylinder briquetting 58, joint pin 59, cylinder axis 60, cylindrical base 61, cylinder spanner 62 and cylinder and leave a blank and 63 jointly to form.Fixing cell wall 19 is the sphenoid of a upper-thin-lower-thick, and it is vertically connected at an edge of fixed base plate 25, and the configuration of fixing cell wall 19 wedge body makes the curved-surface structure that can better attach and be suitable for human body.Another marginal center of fixed base plate 25 is connected with cylindrical base 61, and one end dissociative and centre are run through cylinder axis 60; The two ends of axle are respectively connected with mobilizable cylinder briquetting 58, can along cylinder axis 60 axial rotation; Be connected with the cylinder spanner 62 of outer rim is static by joint pin 59 between two cylinder briquettings 58, centre is left cylinder and is left a blank 63, the fixing tenon 20 that corresponding with it is on fixing cell wall 19, fixing tenon 20 is designed to the end and slightly pushes up thin circular cone structure, realizes linearly fastening; Its surface distributed has the tenon stricture of vagina 27 of a circle circle, can increase the frictional force between the film fourth of the twelve Earthly Branches 3 and fixing tenon 20.The outer of cylinder briquetting 58 and fixing cell wall 19 are designed with near place and compress stricture of vagina 57, for increasing the frictional force between cylinder briquetting 58 and film bar etc., and fastening locking effect.

embodiment 2using method of the present utility model

The first step: first locking.Patient lies low in the treatment tank 35 of " U " shape, operation technician two people cooperation is carried out jointly, Tenon stagewise body film is immersed the thermostatic water tank of 60 ~ 70 degrees Celsius, after fully softening, everyone mentions the film bar handle 5 on one side separately respectively, be covered in the position needing stationary positioned, and stretched softening low temperature thermo-plastic planking 1 by relative film bar 2, in the fixing tenon 20 film fourth of the twelve Earthly Branches 3 put in place on fixed mount.Because thin circular cone structure is slightly pushed up at fixing tenon 20 end, can make to combine both are linearly fastening, multi-turn tenon stricture of vagina 27 structure can keep fixation clip static, and first locking completes.

Bis-Walk: second locking.Upset both sides totally two cylinder briquettings 58, are upwards rotated by cylinder axis 60, and compress stricture of vagina 57 and contact with each other and locking with film bar (fixed object), object structure will be stopped by cylinder briquetting 58 and be locked in wherein.Compress stricture of vagina 57 pairs of film bars generation pressure owing to forcing due to the bias design of cylinder briquetting 58, be then finally fastened and fixed, second locking completes.

Treat that the low temperature thermo-plastic planking aftershaping that hardens completes.Follow-up formal therapy is according to the low temperature thermo-plastic planking of molding, and fixing means is consistent.

embodiment 3radiotherapy body fixed mount integral type compares with stagewise, and result is see table 1.
