Description

Technical Field

[0001] The utility model relates to medical related fields, and more specifically to a head and neck radiotherapy mold. Background Art

[0002] Before patients undergo head and neck radiotherapy, in order to ensure the effectiveness of the radiotherapy, they need to remain motionless, so a mold that fits the patient's body shape needs to be made before the operation. The head and neck radiotherapy mold is made of thermoplastic film, which is placed in hot water at 70 to 75 degrees Celsius to soften and stretch it into a shapeable state. However, since the mold has a small hole mesh structure, some hot water will be scooped up when it is taken out of the hot water. The gravity of the hot water will deform the softened thermoplastic film, affecting the production of the patient's mold. Utility Model Content

[0003] The main technical problem solved by the utility model is to provide a head and neck radiotherapy mold. The device can ensure that the thermoplastic film will not be deformed due to the gravity of water when it is taken out from hot water, thereby ensuring the accuracy of the patient mold manufacturing.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] A head and neck radiotherapy mold comprises a mold frame, in which a thermoplastic film is arranged. The invention is characterized in that a backing film for supporting the thermoplastic film is installed on the mold frame.

[0006] As a further optimization of the technical solution, the utility model provides a head and neck radiotherapy mold, and the mold frame is evenly provided with a plurality of through holes for position fixing.

[0007] As a further optimization of the technical solution, the utility model provides a head and neck radiotherapy mold, wherein the mold frame is provided with an embedding groove, and the pressure strip presses the edge of the back film into the embedding groove.

[0008] As a further optimization of the technical solution, both ends of the pressure strip of the head and neck radiotherapy mold of the utility model are provided with hand-pinching pieces for easy pulling out.

[0009] As a further optimization of the technical solution, the back film of the head and neck radiotherapy mold of the utility model adopts a high temperature resistant transparent plastic film.

[0010] As a further optimization of the technical solution, the back membrane of the head and neck radiotherapy mold of the utility model is provided with a plurality of drainage holes for facilitating drainage.

[0011] The beneficial effects of the head and neck radiotherapy mold of the utility model are:

[0012] Place the head and neck radiotherapy mold in hot water, ensure that the back film is at the bottom and the thermoplastic film is at the top. When taking it out, due to the support of the back film, the water on the thermoplastic film will not flow out from the grid of the thermoplastic film, but from the edge of the thermoplastic film, so as to achieve the purpose of supporting the thermoplastic film and ensure that the thermoplastic film will not be deformed when it is taken out. When in use, after aligning the head and neck radiotherapy mold with the patient, pinching the hand pinch piece can facilitate the strip to be pulled out of the embedded groove. After removing the back film, the mold can be shaped for the patient. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0014] Figure 1 The utility model is a structural schematic diagram of a head and neck radiotherapy mold.

[0015] Figure 2 for Figure 1 Schematic diagram of the locally enlarged structure of A in the middle.

[0016] In the figure: a mold frame 1; a through hole 11; an embedding groove 12; a thermoplastic film 2; a back film 3; a drainage hole 31; a pressure strip 4; and a hand-kneading piece 5. DETAILED DESCRIPTION

[0017] Embodiment 1: Figure 1 and Figure 2 As shown, a head and neck radiotherapy mold comprises a mold frame 1, in which a thermoplastic film 2 is arranged, and the characteristic is that: a back film 3 for supporting the thermoplastic film 2 is installed on the mold frame 1, a plurality of through holes 11 for position fixing are evenly arranged on the mold frame 1, an embedding groove 12 is arranged on the mold frame 1, and the embedding groove 12 runs through the entire mold frame 1, and a pressure strip 4 presses the edge of the back film 3 into the embedding groove 12 to lay the back film 3 flat, and also makes the pressure strip 4 stably embedded in the embedding groove 12, and both ends of the pressure strip 4 are provided with a hand pinch piece 5 for easy extraction, and the pressure strip 4 can be easily extracted from the embedding groove 12 by pinching the hand pinch piece 5, so as to remove the back film 3, and the back film 3 is made of a high temperature resistant transparent plastic film, and the use of a transparent plastic film makes it easier to observe whether the thermoplastic film 2 is aligned with the patient's head, and a plurality of drainage holes 31 for easy drainage are arranged on the back film 3, and the drainage holes 31 can quickly drain water without affecting the supporting effect of the back film 3 on the thermoplastic film 2.

[0018] The working principle of the head and neck radiotherapy mold of the present invention is as follows:

[0019] Place the head and neck radiotherapy mold in hot water, ensure that the back film 3 is at the bottom and the thermoplastic film 2 is at the top. When taking it out, due to the support of the back film 3, the water on the thermoplastic film 2 will not flow out from the grid of the thermoplastic film 2, but will flow out from the edge of the thermoplastic film 2, thereby achieving the purpose of supporting the thermoplastic film 2 and ensuring that the thermoplastic film 2 will not be deformed when it is taken out. When in use, after aligning the head and neck radiotherapy mold with the patient, pinching the hand pinch piece 5 can facilitate the extraction of the pressure strip 4 from the embedding groove 12. After removing the back film 3, the mold can be shaped for the patient.

[0020] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention also fall within the protection scope of the present invention.
