A marking line device suitable for scar development after breast cancer surgery

Abstract

The invention discloses a marking line device suitable for postoperative scar development of breast cancer. Part 1, one of the horizontal shafts is equipped with a dry cotton thread roll, and the other horizontal shaft is equipped with an adhesive tape roll, and the box is equipped with an auxiliary glue that makes the dry cotton thread of the dry cotton thread roll and the adhesive tape of the adhesive tape roll bonded together. The dry cotton thread tail section of the dry cotton thread roll penetrates into the lower cavity and soaks in the contrast agent in the lower cavity, then passes out of the lower cavity and extends into the upper cavity, and extends into the auxiliary adhesive piece together with the adhesive tape tail section of the adhesive tape roll. The marking line is formed by combining and fixing, and then penetrates the upper end of the auxiliary adhesive part and the top of the box body, and a cutting knife is provided at the position where the box body is penetrated by the marking line. The marking line device suitable for postoperative scar development of breast cancer does not produce artifacts, does not affect the radiotherapy plan, and does not generate additional dose calculation for the radiotherapy plan.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a marking line device suitable for developing scars after breast cancer surgery. Background technique [0002] Breast cancer is the malignant tumor with the highest incidence rate in women worldwide. According to statistics, the incidence of breast cancer accounts for 7% to 10% of all kinds of malignant tumors in the whole body. Morbidity is often related to heredity, and the incidence rate of women before and after menopause at the age of 40 to 60 is higher, and only 1% to 2% of breast patients are men. At present, the main treatment methods in our country are surgery, radiotherapy, chemotherapy, endocrine therapy and other comprehensive treatments. With the rapid development of radiation therapy technology, it has entered the "three precision era" of image-guided radiation therapy (IGRT), that is, precise positioning, precise design, and precise irradiation. Before radiothera...
