Breast cancer postoperative scar developing marking line device

Abstract

The invention discloses a breast cancer postoperative scar developing marking line device which comprises a box body, a lower cavity and an upper cavity are formed in the box body, a contrast agent is injected into the lower cavity, two first horizontal shaft parts are installed at the position of the upper cavity, a dry cotton thread roll is installed on one first horizontal shaft part, an adhesive tape roll is installed on the other first horizontal shaft part, an auxiliary bonding piece enabling dry cotton threads of the dry cotton thread roll and adhesive tape of the adhesive tape roll to be bonded and fixed together is installed in the box body, the tail section of the dry cotton threads of the dry cotton thread roll penetrates into the lower cavity to be immersed in the contrast agent of the lower cavity, then penetrates out of the lower cavity to stretch into the upper cavity, and jointly stretches into the auxiliary bonding piece together with the tail section of the adhesive tape of the adhesive tape roll to be bonded and fixed to form a marking line, and dry cotton threads penetrate out of the upper end of the auxiliary bonding piece and the top of the box body, and a cutting knife is arranged at the position, penetrated by the marking line, of the box body. The marking line device suitable for breast cancer postoperative scar development does not generate artifacts, does not influence a radiotherapy plan, and does not generate extra dose calculation for the radiotherapy plan.
