Description

Quick positioning hole digger for radiotherapy thermoplastic film Technical Field The invention relates to the technical field of thermoplastic film perforation, in particular to a quick positioning perforation device for a radiotherapy thermoplastic film. Background In radiotherapy, after a patient is fixed by the low-temperature thermoplastic memory film, the low-temperature thermoplastic memory film is required to be perforated in a focus area of the patient, so that the patient skin dose is reduced, the body surface marking of the patient is assisted, the surgical fistulization opening stimulation is reduced, the vomiting of the patient is prevented, the treatment risk and uncertainty of the patient are reduced, and the treatment accuracy and the treatment effect are improved. The method for perforating the low-temperature thermoplastic memory film at the present stage mostly adopts modes of art designing cutters, scissors, punchers and the like, if the art designing cutters and the scissors are adopted to perforate the low-temperature thermoplastic memory film, the thermoplastic film is thicker and has high hardness, the perforation process is time-consuming, labor-consuming and limited in position, the quality and the efficiency are low, burrs are easy to occur at the edges of the incisions, the comfort of patients is poor, patients and medical staff are easy to be injured by mistake, if the punchers are adopted to perforate the low-temperature thermoplastic memory film, the shape of the hardened thermoplastic film is irregular, the thermoplastic film is arched, the punchers are inconvenient to align with the perforating positions in the positioning and perforating process, the position deviation of the punchers is easy to occur in the perforating process, the perforating operation difficulty is increased, and the perforating efficiency is reduced.
