Description

Technical Field

[0001] The present invention relates to the field of tumor auxiliary treatment, and in particular to a tumor intervention auxiliary treatment device. Background Art

[0002] In the existing mainstream internal medicine treatment process, the treatment of directly taking drugs is relatively conservative and its effect needs to be improved. Therefore, interventional treatment methods are usually used in the existing oncology treatment. The treatment method delivers the drugs directly to the lesion site, which can accurately and directly reach the local lesion without major trauma. Therefore, it has the advantages of accuracy, safety, high efficiency, wide adaptability, and few complications. It has now become the preferred treatment method for some diseases, especially for oncology treatment. Compared with internal medicine treatment, interventional treatment allows drugs to act directly on the lesion site, which can not only greatly increase the drug concentration in the lesion site and improve the efficacy, but also greatly reduce the drug dosage and reduce the systemic side effects of drugs. Moreover, it does not require surgery to expose the lesion. Generally, only a skin incision of a few millimeters is needed to complete the treatment. The epidermis is less damaged and the appearance is beautiful. Most patients only need local anesthesia instead of general anesthesia, which reduces the risk of anesthesia.

[0003] The existing new type of oncology internal medicine drug interventional treatment device, in which the use of syringes is relatively common, the drug for treating tumors will be drawn into the syringe, and then the syringe will push the drug solution into the human body, but most of them are manually controlled, and the speed of manual drug injection is difficult to adjust. The drug solution injected into the human body too fast will cause pain and soreness to the patient. At the same time, there is a temperature difference between the drug solution and the human body, which is easy to cause other discomfort to the patient. In addition, during puncture, the puncture depth cannot be controlled, and the applicability is insufficient. Summary of the invention
