Description

Technical Field

[0001] The invention relates to the technical field of radiotherapy heat shrinkable films, and in particular to a diversified intelligent hole-opening device for radiotherapy thermoplastic films. Background Art

[0002] Thermoplastic film is a hard sheet at room temperature, which can become soft after heating and can be shaped according to the patient's body contour. It hardens and takes shape after cooling at room temperature. Thermoplastic film is not only suitable for laryngeal cancer tracheotomy, but also for patients with common lung cancer, cervical cancer and the like. It can also be used for some patients with PICC tubes in the chest. After the thermoplastic film is softened in a constant temperature water tank, it is buckled on the surface of the patient's body. After cooling, it is conventionally opened with scissors, which is laborious and easy to cut hands, delaying the radiotherapy positioning time. Manual cutting along the radiotherapy cross laser line is inaccurate or uneven and easy to cut the patient's skin.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figure 1-5As shown, a radiotherapy thermoplastic film diversified intelligent hole opening device includes a flat plate seat 1, a support rod frame 2 is arranged on the flat plate seat 1, and the support rod frame 2 is composed of a main rod 21, a side rod 22 and a horizontal rod 23. The bottom of the main rod 21 is installed on the flat plate seat 1, and the side rod 22 is located on one side of the main rod 21. The top of the main rod 21 and the top of the side rod 22 are connected by the horizontal rod 23;

[0023] A slide 5 is slidably mounted on the support rod frame 2, and the slide 5 can move up and down on the support rod frame 2. A first spring 3 is sleeved on the main rod 21, and the bottom end of the first spring 3 is mounted on the upper surface of the flat plate seat 1, and the top end is mounted on the lower surface of the slide 5. A limit plate 231 is provided on the side rod 22, and a second spring 4 is sleeved on the side rod 22, and the top end of the second spring 4 is fixed on the lower surface of the limit plate 231, and the bottom end is fixed on the upper surface of the slide 5; the support rod frame 2 guides the slide 5 to slide up and down. After the slide 5 moves down, under the pulling force of the first spring 3 and the second spring 4, the slide 5 can be quickly reset.

[0024] A cross laser 6 is movably mounted at the lower center of the slide 5 . The cross laser 6 can emit a cross-shaped laser. A cutter head 7 is movably mounted below the cross laser 6 .

[0025] A mounting groove is provided in the center of the lower surface of the slide 5, and the cross laser 6 is plugged into the mounting groove. A fastening bolt 51 is threadedly connected to the side of the slide 5, and the front end of the fastening bolt 51 abuts against the cross laser 6. The fastening bolt 51 fixes the cross laser 6. By loosening the fastening bolt 51, the height position of the cross laser 6 can be adjusted.
