Description
技术领域technical field
本实用新型涉及医疗辅助器械领域，具体涉及一种皮下植入式腹腔化疗装置。The utility model relates to the field of medical auxiliary devices, in particular to a subcutaneously implanted abdominal cavity chemotherapy device.
背景技术Background technique
腹腔内化疗是一种常见的化疗方式，可有效治疗腹腔内恶性肿瘤(包括原发肿瘤和转移肿瘤)，控制肿瘤进展，改善患者生存，提高患者生活质量。当前临床实践中，腹腔内化疗类型主要分为外穿刺式腹腔化疗和植入式腹腔化疗，后者具有感染几率小，操作简便，可长期、反复进行化疗等优点。但传统的植入式腹腔化疗装置容易因腹腔液体凝结、肿瘤生长包裹等，导致化疗装置堵塞的风险，限制了其临床应用及推广。Intraperitoneal chemotherapy is a common chemotherapy method that can effectively treat intra-abdominal malignant tumors (including primary tumors and metastatic tumors), control tumor progression, improve patient survival, and improve patients' quality of life. In current clinical practice, the types of intraperitoneal chemotherapy are mainly divided into external puncture intraperitoneal chemotherapy and implantable intraperitoneal chemotherapy. The latter has the advantages of low infection probability, simple operation, and long-term and repeated chemotherapy. However, the traditional implantable intraperitoneal chemotherapy device is prone to the risk of blockage of the chemotherapy device due to intraperitoneal fluid coagulation and tumor growth encapsulation, which limits its clinical application and promotion.
