Puncture equipment for hepatobiliary department

Abstract

The invention relates to puncture equipment for hepatobiliary department. The equipment is characterized in that the left end of a puncture needle sleeve is provided with a tip part, the right end of the puncture needle sleeve is connected with a needle sleeve connector, the needle sleeve connector is hollow, a flow guide pipe is arranged below the end, connected with the puncture needle sleeve, of the needle sleeve connector, a through hole is formed in the center of the other end of the needle sleeve connector, an isolation plug is arranged in the needle sleeve connector, a puncture needle core is positioned inside the puncture needle sleeve, the left end of the puncture needle core is a tip end, and is matched with the tip part of the puncture needle sleeve, the right end of the puncture needle core penetrates through the isolation plug and the through hole in sequence, is located outside the needle sleeve connector and is connected with a needle core connector, a limiting piece comprises a bushing, a fastening nut and arc-shaped rubber limiting blocks, the puncture needle sleeve is sleeved with the bushing in a sliding mode, threads are arranged on the outer surface of the bushing, the bushing is sleeved with the fastening nut in a threaded mode, the multiple arc-shaped rubber limiting blocks are annularly and fixedly arranged at the right end of the bushing, and the thickness of the arc-shaped rubber limiting block is gradually increased outwards from the connecting end of the arc-shaped rubber limiting block and the bushing, According to the invention, the puncture equipment has the advantages of being reasonable in structure, convenient to use and high in puncture accuracy.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a puncture device for the hepatobiliary department. Background technique [0002] Obstructive jaundice caused by hepatobiliary and pancreatic system diseases is a common disease. The traditional treatment method is surgery. Traditional surgery has the disadvantages of large trauma and many complications. With the advancement of minimally invasive technology and equipment, percutaneous biliary drainage or bile duct drainage Stent implantation is widely used clinically to treat obstructive jaundice caused by biliary stenosis and pancreatic disease, which is mainly diagnosed and treated through percutaneous liver puncture to cholangiography; , because it is difficult to reasonably control the insertion depth of the puncture needle, which leads to the problem of poor puncture accuracy; therefore, in order to solve the above problems, it is very important to develo...

[0002] Obstructive jaundice caused by hepatobiliary and pancreatic system diseases is a common disease. The traditional treatment method is surgery. Traditional surgery has the disadvantages of large trauma and many complications. With the advancement of minimally invasive technology and equipment, percutaneous biliary drainage or bile duct drainage Stent implantation is widely used clinically to treat obstructive jaundice caused by biliary stenosis and pancreatic disease, which is mainly diagnosed and treated through percutaneous liver puncture to cholangiography; , because it is difficult to reasonably control the insertion depth of the puncture needle, which leads to the problem of poor puncture accuracy; therefore, in order to solve the above problems, it is very important to develop a hepatobiliary puncture device with reasonable structure, convenient use and high puncture accuracy.
