[0002] Treatment for ovarian cancer usually depends on the type of cancer, stage, the patient's overall health, and other individual factors. Treatment usually uses a combination of methods, including surgery, chemotherapy, targeted therapy, immunotherapy, etc. Surgery is one of the main methods for treating ovarian cancer and is usually used for patients who are diagnosed at an early stage. The goal of surgery is to remove as much tumor tissue as possible to reduce the risk of cancer recurrence.

[0003] After searching, it is found that the current surgical treatment tends to be non-invasive tumor removal, which requires the administration of drugs. The traditional way is to open one or more surgical holes in the abdomen to perform surgery and drug administration at the same time; this will undoubtedly bring greater pain to the patient and difficulties in postoperative recovery care. Therefore, we propose a new multi-channel drug delivery device that can deliver drugs simultaneously during surgery to reduce the basic trauma of the patient. Summary of the invention
