Abstract

The invention relates to a magnetic resonance compatible puncture needle which comprises an outer needle and an inner needle, wherein the inner needle is embedded in the outer needle. The magnetic resonance compatible puncture needle is characterized in that the outer needle is made of pure titanium, and the inner needle is made of titanium alloy. The outer needle of the magnetic resonance compatible puncture needle is made of the pure titanium material, and the inner needle is made of the titanium alloy material, thereby reducing the size of the puncture needle under magnetic resonance imaging and being convenient for better judging the position of the puncture needle.

Description

【Technical field】

[0001] The invention relates to a medical device, in particular to a magnetic resonance compatible puncture needle. 【Background technique】

[0002] The puncture needle is the most basic interventional device, which can be used to directly penetrate into the tumor or cyst cavity for diagnosis and treatment such as suction, flushing, drainage, biopsy or ablation; it can also be used to open the channel of the skin and blood vessels or the brain, bile duct, Urinary tract, stomach, abscess cavity and cyst cavity and other tissues, and then guide wire, catheter, drainage tube, etc. are introduced for treatment. Traditional puncture needles are widely used in the medical field, but their application in MRI-guided intervention is limited. Magnetic resonance guided intervention refers to the use of percutaneous puncture technology and catheter technology to treat some diseases or obtain histology, bacteriology, physiology and Biochemical materials to clarify the ...
