Tracheal cavity wall tumor chemotherapy drug interventional device

Abstract

A tracheal cavity wall tumor chemotherapy drug interventional device includes an outer sheath tube and an inner push rod. The inner push rod is coaxially inserted into the outer sheath tube, the rearend of the inner push rod is provided with a thumb buckle, the rear end of the outer sheath tube is provided with an index finger buckle, and the inner push rod is longer than the outer sheath tube. The front end of the inner push rod is fixedly provided with a hexagonal installation ring, and a drug injection component is installed on the installation ring. In conclusion, drug injection needles can expand and puncture tumor tissue by controlling the index finger and the thumb, the drug injection needles are uniformly distributed and can convey chemotherapy drugs into the tumor tissue uniformly, the chemotherapy effect is good, the situation is avoided that the tumor tissue needs to be punctured several times, operation steps are reduced, and tumor metastasis caused by multiple punctures is avoided.

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. Most primary malignant tumors of the trachea grow at the junction of the cartilage ring and the membrane. Squamous cell carcinoma may appear as a mass protruding into the tracheal lumen or ulcerate, and sometimes the cancer may infiltrate the entire trachea. Cystic adenoid carcinoma generally grows slowly and metastasizes later, and sometimes prese...

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
