Lumen wall tumor chemotherapy drug intervention device

Abstract

The cavity wall tumor chemotherapy drug intervention device includes an outer sheath tube and an inner push rod. The inner push rod is coaxially inserted in the outer sheath tube. There is an index finger buckle, the length of the inner push rod is greater than that of the outer sheath tube, and the front end of the inner push rod is fixed with a mounting ring, which is hexagonal in shape, and a drug injection component is installed on the mounting ring; in summary, the present invention controls the index finger Expand the injection needle with your thumb and puncture it into the tumor tissue. The injection needle is evenly distributed, and the chemotherapy drug can be evenly injected into the tumor tissue. The chemotherapy effect is good, and it avoids multiple punctures on the tumor tissue and reduces the operation steps. Avoid tumor spread caused by multiple punctures.

Description

technical field [0001] The invention belongs to the field of medical technology, and in particular relates to a cavity wall tumor chemotherapeutic drug intervention device. Background technique [0002] The respiratory tract, also known as the airway, is the channel through which the airflow passes when the lungs breathe. It is bounded by the lower edge of the cricoid cartilage. The nose, pharynx, and larynx are collectively called the upper respiratory tract; the trachea, bronchi and lung organs are collectively referred to as the lower respiratory tract. Tumors in the airway are divided into primary tumors and secondary tumors. There are many types of primary tracheal malignant primary tracheal benign tumors, with different shapes, slow growth, smooth surface, complete mucosa, often with tumor pedicles, and no metastasis , but if the excision is not complete, it is easy to relapse. Papilloma mostly occurs in the membranous part of the trachea, protrudes into the bottom of...

Problems solved by technology

[0004] The current method of injecting drugs into the tumor is: insert an injection device with a hooked needle at the head end and a drug injection tube at the tail end, and a sleeve is arranged on the outside, and then insert the device into the patient's airway, and then insert the needle The outer sheath is pushed out and inserted into the tumor tissue for drug injection. The device has only one drug injection needle during injection. For tumors growing around the airway, multi-point punctures are required to uniformly administer drugs to ensure the effect of drug injection. At this time It is difficult to ensure uniform puncture of the airway wall when using a needle for multiple punctures, which reduces the effect of drug injection, and the needle contains tumor cells during multiple punctures, which is equivalent to artificially planting tumor cells in other parts, resulting in tumor spread
