Embodiment 1

[0025] Example 1 Radiation therapy head and neck positioning craniofacial bone eccentric sliding ball fixator

[0026] see figure 1 , figure 2 , image 3 , the structure consists of the head base plate 147, the maxilla (triangle card) support component 229, the bite device sliding ball component 230, the right branch of the tripod vault 256, the left branch of the tripod vault 257, the anterior hole of the jaw abutment tooth 259, the nasal root fixer 260, the nasal root The base tooth front hole 261, the tripod dome front support 262 and the cam lock post 263 are composed. The overall structure is a three-legged support structure. The three cam-type locking posts 263 are three fulcrums and are in a "pin" shape. A three-legged dome structure with an arc is connected between the two cam lock posts 263 at the bottom of the "pin" structure; see image 3 One end of the front support 262 of the tripod dome is connected to the cam-type locking column 263, and the other end is c...

Embodiment 2

[0033] Embodiment 2 uses principle and method:

[0034] The first step: the locking of the tripod dome structure and the head base plate 147 .

[0035] ①Lock: (see Figure 20 ) Due to its own material factors, the four expansion flaps 10 are always kept in a mutually (adducted) closed state without being subjected to lateral external forces, and the outer diameter of the lower flap edge 168 is smaller than the expansion hole on the latch seat 153 (ie, the head base plate 147). 152 diameter, the expansion valve 10 is smoothly inserted into the corresponding expansion hole 152, and the anti-rotation notch 160 corresponds to the anti-rotation pin 148 until the lower wall of the column seat 167 and the upper wall of the plug seat 153 are abutted. ②Lock: see Figure 19 , when the lower wall of the column seat 167 and the upper wall of the plug seat 153 (ie, the head base plate 147 ) fit together, the plug positioning protrusion 11 on the outer side wall of the expansion valve 10 ...

Abstract

The invention provides a radiation therapy head and neck positioning skull and facial bone eccentric sliding ball fixing rack. The radiation therapy head and neck positioning skull and facial bone eccentric sliding ball fixing rack is constituted by a head bottom plate, an upper jaw bone supporting assembly, an occluder sliding ball assembly, a three-leg fornix right support, a three-leg fornix left support, a jaw base tooth front hole, a nasion fixing device, a noise base tooth front hole, a three-leg fornix front support 262, and a cam type locking column. Relative fixing is realized by teeth biting supporting points of a fixing support, and the supporting body of the fixing support is used to press the bone mark of the head to realize the relative fixing of the nasion part, and by adopting cooperation with a special positioning head rack series, limiting fixing of a head and a neck of a human body is realized, and zero displacement is realized or almost realized, and therefore disadvantages and defects of conventional head radiation therapy positioning structures are effectively solved. The radiation therapy head and neck positioning skull and facial bone eccentric sliding ball fixing rack has advantages of reasonable design, convenient and safe operation, obvious fixing effect, strong practicability, and strong versatility.

Description

technical field [0001] The invention belongs to the technical field of radiotherapy human body positioning devices, and relates to a radiotherapy head and neck positioning craniofacial bone eccentric sliding ball fixing frame. This type of fixation device is suitable for the fixation of parts with large fluctuations in the curves of the human head, neck and shoulders. It is an important part of precise positioning and implementation in modern radiotherapy. Background technique [0002] Silica gel is a highly active adsorption material, which is an amorphous substance with a chemical formula of mSiO2·nH2O; it does not react with any substance except strong alkali and hydrofluoric acid, is insoluble in water and any solvent, and is non-toxic and tasteless. It has high adsorption performance, good thermal stability, stable chemical properties, and high mechanical strength. Engineers can create a variety of silicone types by adding some special factors. Oral (dental) impression...
