The lower surface of beam 62 has the arcwall face 622 being bonded with nose.
Wherein, horizontal concrete chute 631, the vertical chute 621 and 611 place of opening up of longitudinal chute, which are provided with, records the shifting of its inner part
The graduation mark of dynamic length carries out Rapid reset according to the data of record when graduation mark herein is mainly used for Patients Treated by Radiotherapy.
The position fixing process of Ya Bi mechanism 6 are as follows: neck thermoplastic film 2 is completely covered on the neck of patient and is fixed on corresponding
Retaining mechanism 13 on after, pressure nose overarm 61 is adjusted in the position of horizontal concrete chute 631 according to the face contour of patient, makes to press nose outstanding
Beam 61 is located at the surface of patient nose；Adjustment pressure nose stringer 62 is located at position and the vertical chute 621 of longitudinal chute 611 later
Extend the length of pressure nose overarm 61, so that the arcwall face 622 of pressure nose stringer 62 is contacted with the nose of patient, later again by setting
The moving displacement of the graduation mark record pressure nose overarm 61, pressure nose stringer 62 set, wherein pressure nose stringer 62 needs to record both direction
Displacement.
As shown in figure 5, pressure nose stringer 62 includes pressure nose mounting rail 625, the vertical chute 621 is provided with pressure nose mounting rail 625
On, it is installed with pressure nose fixture block 624 in the lower end of pressure nose mounting rail 625, the lower end of pressure nose fixture block 624 is installed with pressure nasal cushion 623, pressure
