Abstract

The invention provides an ultrasonic needle. The ultrasonic needle comprises a needle, an outer tube and a handle, wherein the needle is internally arranged in the outer tube, the proximal end of the needle is connected with a needle core connector, a guide pipe fixing member and a needle adjusting pipe which are connected with each other are sequentially arranged on the needle core connector towards the distal end side, a proximal end locking member and a needle withdraw adjusting handle which are connected with each other sleeve the needle adjusting pipe, the needle withdraw adjusting handle is movably connected with a needle withdraw adjusting lock, the needle withdraw adjusting lock is provided with a guiding cavity with snapping grooves, the guiding cavity is embedded in the needle withdraw adjusting handle, the snapping grooves comprise an axial guiding groove and a locking groove in the radial direction of the distal end of the guiding groove, a snapping pin adapted to the snapping grooves is arranged inside the distal end of the needle withdraw adjusting handle, and a pressure spring is arranged between the guiding cavity and the needle withdraw adjusting handle.

Description

technical field [0001] The invention relates to a medical device, in particular to an ultrasonic needle capable of entering into a human body for puncturing. Background technique [0002] Under the guidance of bronchoscopic ultrasonography / endoscopic ultrasonography, tissue or cytology samples are obtained after puncture and aspiration, which is often called EBUS / EUS examination in clinical practice. EBUS can locate the specific location of extrabronchial lesions through ultrasound (conventional bronchoscopy can only see the lesions in the trachea and bronchus), and avoid blood vessels under the guidance of color Doppler, and obtain the corresponding location through needle aspiration and biopsy. Cells and tissues, so as to achieve the purpose of diagnosing diseases. EUS is more accurate in staging primary tumors and local nodules in pancreatic cancer. [0003] The key to EBUS / EUS examination is to successfully obtain the required tissue or cytology samples, and the biopsy...
