Tumor minimally invasive interventional therapy puncture needle

Abstract

The invention discloses a tumor minimally invasive interventional therapy puncture needle, and relates to the field of medical instruments. The puncture needle aims at solving the problems that an existing puncture success rate is limited, puncture points of important organs are difficult to operate. According to the scheme, the puncture needle comprises a needle body, one end of the needle body is in threaded connection with a positioning base, the needle body penetrates through the positioning base and extends into the positioning base, adjusting bases are arranged on the two sides of the positioning base, adjusting lugs are arranged on the surfaces of the outer sides of the adjusting bases, positioning plates are arranged on the outer sides of the adjusting lugs, and supporting rods are fixedly arranged on the inner sides of the positioning plates. After a puncture head is punctured into the body of a patient, the positioning plates can be pulled to move away two limiting plates, then the direction of the adjusting lugs is rotated to push the positions of guide rods, so that the positions of the guide rods at the other end are slightly changed, the guide rods and an infusion cavity are filled with connecting blocks, the infusion cavity and the puncture head of the needle body can be driven to perform position fine adjustment, and therefore one-time puncture and multiple-time fine adjustment work on the patient is achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a puncture needle for minimally invasive interventional treatment of tumors. Background technique [0002] Tumors in medicine refer to abnormal lesions of cells, which cause uncontrolled proliferation of cells in some parts of the body, and often gather into lumps. Tumors are divided into benign tumors and malignant tumors. Benign tumors grow slowly and have a smooth surface. Invades adjacent normal tissues, and a capsule is often formed around the tumor, so benign tumors with a clear boundary with normal tissues are generally not fatal, most of them can be completely resected, and recurrence is rare; cancer is the most common malignant tumor, malignant Tumors are divided into "cancer" of epithelial origin and "sarcoma" of mesenchymal origin. In malignant tumors, these proliferating cells will not only gather to form a tumor, but also spread to other parts of the body to proliferat...

AI Technical Summary

Problems solved by technology

The clinical method of treating tumors is to remove the tumor to prevent its continued growth from causing harm to the human body. However, the surgical wound of tumor resection is large and difficult to recover, which has caused great pain to the patients.

[0003] Most of the existing instruments for interventional tumor therapy are single puncture needles, and the punctures are all manual operations. For particularly small target tissues, the success rate of punctures is relatively low

One-needle puncture is relatively blind, and the success rate is limited; for some puncture points with important organs nearby, it is not easy to operate. Therefore, it is necessary to invent a puncture needle for minimally invasive interventional therapy of tumors
