Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Figure 1, tumor radiotherapy head fixing device, including head positioning mechanism and integral installation mechanism；Described
Head positioning mechanism includes cricoid protective shell 1；Irradiation notch 2 is provided with along generatrix direction on protective shell 1；1 middle part edge of protective shell
Circumferencial direction is provided with breathing port 3；1 outer wall of protective shell is along the circumferential direction uniformly provided with threaded hole 4；The cooperation of 1 inner wall of protective shell is solid
Surely there is constraint air bag 5；Constraint 5 inner wall of air bag is evenly distributed with flexible projection 6；Inflating port 7 is communicated on constraint air bag 5；Inflation
A air valve 8 is installed on mouth 7.
As shown in Fig. 2, the integral installation mechanism includes pedestal 9；Mounting base 10 is provided with above pedestal 9；Mounting base
10 arc-shaped structures；10 inner wall of mounting base and 1 outer wall corresponding matching of protective shell；It is provided in mounting base 10 opposite with breathing port 3
The conducting orifice 11 answered；Supporting block 12 is fixed in the middle part of 10 outer wall of mounting base；Support is respectively fixed at left and right sides of 10 outer wall of mounting base
Plate 13；12 lower end of supporting block is fixed with universal set 14；13 lower section front and rear sides of supporting plate are respectively arranged with vertical screw rod 15；Ten thousand
