[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Such as Figures 1-4As shown in the figure, a radiotherapy head positioning film includes a positioning film 1 and a fixing strip 2. The fixing strip 2 is detachably connected to the side of the positioning film 1. The fixing strip 2 includes an upper fixing strip 201 and a lower fixing strip 202. One side of the wall of the upper fixing strip 201 is fixedly connected with a needle body 3. One side of the wall of the lower fixing strip 202 is provided with a groove 4. The upper fixing strip 201 and the lower fixing strip 202 are buckled together. The needle body 3 passes through the ventilation holes at different positions on the side of the positioning film 1 and then is embedded in the groove 4. The upper fixing strip 201 and the lower fixing strip 202 are tightly attached and connected to the radiotherapy base 7 through a plunger 6. The positioning film is integrally formed by a face film and a head film. The face film is square, and the head film is trapezoidal.

[0021] Specifically, according to the sizes of the patient's head and face, the operator connects the fixing strip 2 to different positions on the side of the positioning film 1 in advance. The needle body 3 of the upper fixing strip 201 is inserted into different positions on the side of the positioning film 1. Then, the needle body 3 is embedded in the groove 4 of the lower fixing strip 202, realizing the function of adjusting the fixing strip 2 at different positions on the side of the positioning film, pulling the positioning film 1 to adapt to the heads and faces of different patients. Finally, the fixing strip 2 is connected to the radiotherapy base through the plunger 6.

[0022] Specifically, a plurality of the needle bodies 3 are vertically arranged on one side of the wall of the upper fixing strip 2. The plurality of needle bodies 3 can be vertically arranged in the middle of the wall or on one side of the wall according to the actual situation. The needle body 3 is integrally formed with the upper fixing strip 2. Using the needle body 3 is convenient for passing through different positions of the positioning film 1 without additionally setting through holes on the positioning film 1.

[0023] Specifically, the fixing strip 2 is square.

[0024] In one embodiment, through holes 5 are opened at the four corners of the walls of the upper fixing strip 201 and the lower fixing strip 202. The plunger 6 passes through the through holes 5 and is threadedly connected in the radiotherapy base, and the upper fixing strip 201 and the lower fixing strip 202 are tightly attached between the radiotherapy base and the plunger 6.

[0025] Specifically, a handle can be provided at the head end of the plunger 6 to facilitate rotating the plunger 6.

[0026] In another embodiment, two through holes 5 are opened on the walls of the upper fixing strip 201 and the lower fixing strip 202, and the two through holes 5 are respectively located at the two short sides of the wall of the fixing strip.

[0027] The upper fixing strip 201 and the lower fixing strip 202 match in specification and size. The position and specification of the needle body 3 and the groove 4 match, and the depth of the groove 4 is greater than the length of the needle body 3, so that the needle body 3 will not protrude outside the lower fixing strip 202, thus preventing the needle body 3 from injuring the human body.

[0028] Threaded holes are formed in the radiotherapy base 7, and the depth of the threaded holes is greater than the length of the threaded section of the plunger 6.

[0029] Specifically, the plunger 6 includes a head end and a threaded section. The depth of the threaded hole is greater than the length of the threaded section of the plunger 6, so that the threaded section of the plunger 6 is completely screwed into the radiotherapy base, so that the upper fixing strip 201 and the lower fixing strip 202 are closely attached to the head end of the plunger and the radiotherapy base, with good stability. When pulling the positioning film 1, the positioning film 1 will not come off from the fixing strip.

[0030] Specifically, the diameter of the head end of the plunger is greater than the diameter of the through hole 5, so that the fixing strip is located between the plunger and the radiotherapy base 7.

[0031] The length of the fixing strip 2 is greater than the length of the side of the positioning film 1, so that the positioning film 1 does not affect the use of the plunger 6.

[0032] The using process of the utility model is as follows:

[0033] First, according to the size of the patient's head and face shape, the operator connects the fixing strip 2 to different positions on the side of the positioning film 1 in advance. The needle body 3 of the upper fixing strip 201 is inserted into different positions on the side of the positioning film 1, and then the needle body 3 is embedded in the groove 4 of the lower fixing strip 202, realizing the function of adjusting the fixing strip 2 at different positions on the side of the positioning film 1;

[0034] After that, the radiotherapy positioning film is placed in a constant temperature water tank at 65°C - 70°C for heat preservation for 1 - 3 minutes, and then taken out and placed on the part of the patient's body to be fixed. The positioning film 1 is stretched evenly, and the position of the fixing strip 2 on the side of the positioning film 1 can be further adjusted according to the patient's feeling to make the tightness of the positioning film 1 on the patient's head appropriate.

[0035] Finally, the fixing strip 2 is connected to the radiotherapy base 7 through the plunger 6.
