Embodiment 1

[0025] see Figure 1-5 , the elastic membrane headrest described in this example includes two frames 1 and a piece of polymer elastic film 2; each frame 1 is made of an upper splint 1-1 made of carbon fiber material, The lower splint 1-2 is composed of an elastic pad 1-3 made of EVA, wherein the upper splint 1-1 and the lower splint 1-2 are arranged above and below the edge of the polymer elastic film 2, and the elastic pad 1-3 is arranged on the upper Between the splint 1-1 and the polymer elastic film 2, six screws 3 are fixed on the upper splint 1-1 through the lower splint 1-2 through the elastic pad 1-3, and the polymer elastic film 2 is clamped and fixed The polymer elastic film 2 is a thin film sheet made of thermoplastic elastomer TPE, its thickness is 0.35mm, the width is equal to the width of the U-shaped panel of the head frame, and the length is equal to the distance between the strong points of the rear acupuncture points of the human body and the wind. distance. ...

Embodiment 2

[0031] see Figure 9-11 and combine Figure 12 In this example, the polymer elastic film 2 is a film sheet made of thermoplastic elastomer TPO, its thickness is 0.8mm, the width is equal to the width of the U-shaped panel of the head frame, and the length is equal to the connecting bottom plate in the head frame 10 used in conjunction with it. The distance between 10-2 and the two supporting members 10-3 of the U-shaped panel 10-1 is located between one end of the U-shaped panel 10-1; the frame 1 is provided with four horizontally elongated mounting holes 4 and a locking adjustment pull The circular through hole 5 of the nail, seven screws 3 are fixed on the upper splint 1-1 by the lower splint 1-2 through the elastic pad 1-3, and the polymer elastic film 2 is clamped and fixed.

[0032] see Figure 9-12 , the implementation method of this example except above-mentioned is identical with embodiment 1.

Abstract

The invention relates to an elastic diaphragm type headrest for radiotherapy positioning, which is characterized in that the elastic diaphragm type headrest comprises two frames and a high-molecular elastic membrane, the two frames are mounted on the lower surfaces of two side edges of a U-shaped panel on a head frame, each frame comprises an upper clamping plate and a lower clamping plate, the upper part and the lower part are clamped and fixed on the edge of the macromolecular elastic film edge; the macromolecule elastic film is a film sheet made of a thermoplastic elastomer, the thickness of the macromolecule elastic film is 0.2-1.0 mm, the width of the macromolecule elastic film is equal to that of the U-shaped panel of the head frame, and the length of the macromolecule elastic film is larger than or equal to the distance between the acupoint strength of the rear portion of the head of the human body and the wind depression and smaller than or equal to the distance between the two supporting components, connected with the bottom plate and the U-shaped panel, in the head frame and located at one end of the U-shaped panel; the frame of the elastic diaphragm type headrest is provided with 3-4 mounting holes and a through hole through which the adjusting blind rivet is locked. The elastic diaphragm type headrest has the advantages of being very simple in structure, short in production period and low in cost.

Description

technical field [0001] The invention relates to the medical field, in particular to a stereotaxic device for tumor radiotherapy, especially a headrest. Background technique [0002] During radiotherapy for the head and neck of the patient, in order to ensure the accurate positioning of the tumor, the patient's head should be fixed before radiotherapy, and then precise treatment will be implemented to ensure the curative effect. At present, the technical solution for fixing the patient's head generally uses two upper and lower low-melting thermoplastic sheets (referred to as thermoplastic sheets, including facial masks and head membranes) for shaping and fixing. Wherein, the head membrane is used to support the back of the patient's head, but since the thermoplastic sheet needs to be heated and softened during shaping, once the patient's head acts on it at this time, the back of the patient's head will touch the base, so it is necessary to Use a headrest with a saddle-shaped...
