Drainage mechanism for breast surgery

Abstract

The invention discloses a drainage mechanism for breast surgery. The drainage mechanism comprises a base, a lifting assembly and a drainage bag. A negative pressure box is arranged in the middle of the upper surface of the base, a sealing cover is buckled to the top end of the negative pressure box, fixing assemblies are symmetrically arranged on the inner wall of the negative pressure box, a vacuum pump is arranged at the right end of the upper surface of a platen of the base, and an air inlet of the vacuum pump communicates with the interior of the negative pressure box through a guide pipe; the drainage bag is fixedly connected with the four fixing assemblies and located in the negative pressure box, a drainage pipe is arranged at the upper end of the drainage bag, a drainage cover is arranged at the top end of the drainage pipe, and an exhaust pipe is arranged at the upper end of the drainage bag; the lifting assembly is arranged at the left end of the upper surface of the base, and the middle of the lifting assembly is clamped with the upper end of the drainage tube; according to the drainage mechanism for breast surgery, the drainage effect is prevented from being affected by separation of the drainage cover and the human skin, and pollution to the negative pressure box and the conical hopper is avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drainage mechanism for breast surgery. Background technique [0002] Breast surgery is the next branch of clinical surgery, which mainly focuses on the surgical aspects of breast diseases: breast anatomy, breast infection, breast tumor pathology, principles of diagnosis and treatment of breast tumors, breast tumor diagnosis, various surgical methods of breast tumor surgery, chemotherapy , radiotherapy, and endocrine therapy, mainly including: breast fibroids, intraductal papillomas, intramammary tumors, and breast cancer, which are mostly related to abnormal estrogen, but cystic hyperplasia of the breast is not a neoplastic disease, but the disease is abnormal hormone metabolism in women Breast parenchymal hyperplasia caused by breast cancer has become one of the most common malignant tumors in women in European and American countries, and its incidence rate remains hig...

[0002] Breast surgery is the next branch of clinical surgery, which mainly focuses on the surgical aspects of breast diseases: breast anatomy, breast infection, breast tumor pathology, principles of diagnosis and treatment of breast tumors, breast tumor diagnosis, various surgical methods of breast tumor surgery, chemotherapy , radiotherapy, and endocrine therapy, mainly including: breast fibroids, intraductal papillomas, intramammary tumors, and breast cancer, which are mostly related to abnormal estrogen, but cystic hyperplasia of the breast is not a neoplastic disease, but the disease is abnormal hormone metabolism in women Breast parenchymal hyperplasia caused by breast cancer has become one of the most common malignant tumors in women in European and American countries, and its incidence rate remains high in developing countries. The incidence rate of breast cancer in China increases by about 3% every year! In Beijing, Tianjin, Shanghai and other large and medium-sized cities, breast cancer has leapt to the top of female malignant tumors! Surgical treatment plays an important role in the local treatment of breast cancer. The drainage device for breast surgery is an auxiliary device used in breast surgery to drain the abscess caused by breast inflammation or tumor so as to treat the breast. It has been widely used in the field of surgical operations. Most of the existing drainage devices and drainage tubes have no support during the drainage process, and it is easy to pull the drainage cover downwards, causing the drainage cover to separate from the human skin and reducing the drainage effect. Moreover, the existing The drainage device usually has two forms, one is disposable, and the inside of the drainage bottle itself has negative pressure. This structure is only suitable for the drainage of a small amount of liquid and cannot be used for long-term drainage. used, but the structure is usually monolithic. In order to avoid pollution, the interior needs to be cleaned and disinfected before it can be used next time. The high frequency of cleaning increases the burden on the staff. For this reason, we propose Drainage mechanism for breast surgery
