Embodiment 1

[0026] Embodiment 1 Mortise and tenon handle type radiotherapy head and neck positioning flat plate fixation frame

[0027] see figure 1 , figure 2 and Figure 16 , the present invention is made up of three parts of fixation frame, headrest and head film, and three need cooperate to use.

[0028] see figure 1 , the fixed frame is composed of a body base plate 305, a base plate slope 300, a body groove 304, a base plate positioning hole 299, a base plate composite positioning hole 301, a mortise and tenon locking component 302, a limiting foot hole 297, a headrest groove 298, and a head base plate 147 , a single locking plate locking assembly 289, a shoulder base plate 290, a body groove slope 295 and an upper limb limiter 296 are jointly formed. The main structure is composed of a head base plate 147 with an isosceles trapezoidal structure, a shoulder base plate 290 with a rectangular structure and a body base plate 305. The rectangular headrest groove 298 is located at ...

Embodiment 2

[0034] Embodiment 2: the present invention uses method

[0035] The first step: preparation work. The fixed frame is placed on the position bed, and then the fixed headrest is put into the headrest groove 298, so that the limiting feet 146 on the fixed headrest are embedded in the limiting foot holes 297 in the groove. Advise the patient to lie down on the fixed frame, so that the head is close to each curved surface of the fixed headrest, that is: the headrest part is in close contact with the occipital bone curve 292, and the neck is in close contact with the strong curve 293.

[0036] Step Two: Upper Body Restraint. When in use: the operator turns the dial 69, and the handle 37 moves up and down to be adjusted to a suitable position held by the patient.

[0037] The third step: pull the mold. Two people cooperate to carry out together, immerse the present invention in the constant temperature water tank of 60~70 degrees centigrade, after fully softening, each person resp...

Abstract

The invention provides a mortise-tenon handle type radiotherapy head and neck positioning slab fixing rack, comprising a fixing rack, a headrest and a head membrane. The slab fixing rack is a head and neck precision radiotherapy positioning fixing system, wherein the braking direction of an upper limb limiter is spirally cross with the adjusting torque to realize one-way braking and limit and fix human head, thereby achieving or approaching zero displacement; and all shortcomings of the present head radiotherapy structure are effectively solved. By matching the special fixing head membrane, the action of the upper limb can be limited, and braking of shoulder joints can be kept, so that precision positioning is achieved. The slab fixing rack is particularly suitable for radiotherapy positioning of head, neck, vertebral columns and other like parts. The slab fixing rack is reasonable in design, convenient to operate, safe, environment-friendly, obvious in fixing effect and strong in practicability and universality.

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 handle type radiotherapy head and neck positioning plate fixing frame, which is a device for positioning the head and neck in radiotherapy, and is suitable for heads with large human body activities. The overall fixation of the neck is an important part of precise positioning and implementation in modern radiation therapy. Background technique [0002] Low-temperature thermoplastic sheet (membrane) is a new type of medical material made of specially synthesized high-molecular polyester through a series of physical and chemical methods. It is used for radiotherapy position fixation, orthopedic external fixation, orthotics, braces, etc. Materials. Because the material has outstanding properties such as non-absorbing radiation, good shaping effect after heating and softening, and unique shape memory function (when the shaping...
