Magnetic resonance compatibility needle biopsy guidance microwave ablation needle

Abstract

The present invention provides a magnetic resonance compatibility needle biopsy guidance microwave ablation needle. The magnetic resonance compatibility needle biopsy guidance microwave ablation needle comprises a needle core used for needle biopsy and an ablation needle body, the ablation needle body comprises a needle, a needle bar and a handle connected in order, the middle portions of the needle bar and the handle are hollow structures which are internally provided with inner tubes adaptive to the needle core, and the inner tube of the ablation needle body can enter a target position of ahuman body along the needle core. The needle biopsy is completed under the MRI guidance, the magnetic resonance compatibility microwave ablation needle with the hollow structure can perform puncture to enter a pathological tissue to develop a microwave ablation operation under the guidance action of the needle core to effectively avoid second needle entering so as to reduce damage to patients andreduce the pollution risk.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a magnetic resonance compatible biopsy-guided microwave ablation needle. Background technique [0002] With the changes in living habits brought about by factors such as environmental pollution and urbanization in the process of industrialization, the cancer morbidity and mortality of Chinese residents have increased significantly. Microwave ablation for tumor treatment is increasingly favored by many patients due to its advantages of less trauma, lower risk, and faster postoperative recovery. [0003] For malignant tumors, whether there are mutations in the pathological classification, typing, or even genetic testing is the primary issue in the process of disease diagnosis and treatment, and the testing results directly determine the corresponding treatment plan. At present, CT-guided percutaneous biopsy is the most common and widely used biopsy puncture, but due to the ionizin...

AI Technical Summary

Problems solved by technology

In addition, after the needle biopsy, the microwave ablation needle will inevitably increase the pain of the patient and increase the incidence of postoperative complications. The current ablation needle still needs to be improved in terms of improving the accuracy of the needle biopsy and reducing the pain of the patient.
