Embodiment 1

[0049] Example 1 Mortise-and-mortise ear-mouth-nose eccentric radiotherapy head and neck positioning negative pressure pillow plate fixing frame

[0050] see figure 1 , figure 2 , image 3 , Figure 16 , Figure 36 and Figure 45 . The innovation is composed of five parts, the fixed base plate, the head membrane, the eccentric fixation frame of the craniofacial bone, the negative pressure pillow and the external ear hole fixer, and the five parts need to be used together.

[0051] 1. See figure 1 , image 3 , the fixed bottom plate is composed of a single locking plate locking assembly 289, a headrest groove 298, a head bottom plate 147, a limit foot hole 297, a shoulder bottom plate 290, a bottom plate positioning hole 299, a bottom plate composite positioning hole 301, a body groove 304, and a body bottom plate 305 , crotch limiter 309, bottom plate slope 300, upper limb limiter 296, expansion hole 152 and mortise and tenon locking assembly 302 are jointly composed....

Embodiment 2

[0074] Embodiment 2: the present invention uses method

[0075] Step 1: Upper Body Restraint. Put the negative pressure head restraint into the head restraint groove 298 on the head base plate 147 . Instruct the patient to lie flat on the fixed frame so that the head and neck are tightly attached to the outer layer of the negative pressure pillow. The operating personnel stirs the dial 69 on the upper limb limiter 296, and the handle 37 moves up and down to be adjusted to a suitable position held by the patient.

[0076] The second step: crotch restriction. The operator turns the dial 69 on the crotch stopper 309, and the handle 37 moves up and down, and the handle 37 is adjusted to clamp the patient's sacrum.

[0077] Step Three: Making the Negative Pressure Headrest

[0078] Use a vacuum pump to evacuate the negative pressure pillow to a certain degree of vacuum negative pressure, so that the plastic particle balls are squeezed each other and shaped according to the pati...

Abstract

The invention provides a tenon ear, mouth and nose eccentric radiotherapy head and neck positioning negative pressure pillow flat plate fixation frame which is composed of a fixation base plate, a head and face bone eccentric fixation frame, a negative pressure pillow, a head membrane and an external ear hole fixer. According to the invention, the flat plate fixation frame is a head and neck accurate radiotherapy positioning and fixing system which matches the special fixed head membrane to restrict the upper limb movement and keep the shoulder joint brake to realize precise positioning; the flat plate fixation frame is particularly suitable for radiotherapy positioning of head, neck, spinal cord and other parts; the limit fixation of the head of a human body is completely realized through the brake limit of the upper limb, the crotch, the occipital bone, the posterior head and neck, the maxilla, the nose root, the facial bone and other rigid bony marks; the head of the human body is completely limited and fixed to reach or approach zero displacement; disadvantages and shortcomings of the current head radiotherapy positioning structure are effectively solved; the flat plate fixation frame has the advantages of reasonable design, convenient operation, safety, environmental protection, obvious fixation effect and high practicability and versatility.

Description

technical field [0001] The invention belongs to the technical field of human body positioning devices in radiotherapy, and relates to a mortise-and-tenon ear, mouth, and nose eccentric type radiotherapy head and neck positioning negative pressure pillow plate fixing frame, which is a device for precise positioning of the head and neck in radiotherapy, suitable for The overall fixation of the head and neck with large human body activities is an important part of precise positioning and implementation in modern radiation therapy. Background technique [0002] Silica gel is a highly active adsorption material, which is an amorphous substance, and its chemical formula is 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 produce a variet...
