A device for removing stones in clinical hepatobiliary surgery

Abstract

The invention discloses a device for removing stones in hepatobiliary surgery clinically, which comprises a sleeve, a first air guide tube and a second air guide tube are sheathed on the inner surface of the sleeve tube, and a second sealing plug is provided on the left end surface of the second air guide tube. The tube is fixedly connected with an annular support frame through the spokes arranged at the lower end of the outer surface. The lower end of the outer surface of the annular support frame is provided with a cylindrical collection tube, and the lower end surface of the cylindrical collection tube is provided with an annular air bag. This stone removal device in clinical hepatobiliary surgery , compact structure, easy operation, small space occupation when used, can quickly and efficiently remove the stones in the patient's liver and gallbladder, the setting of the sewage collection tube can effectively collect the body fluids in the patient's liver and gallbladder, and at the same time can effectively prevent the patient from The body fluid enters the interior of the negative pressure needle tube, and the setting of the annular air bag combined with the annular rubber band can effectively wrap the stones, effectively preventing the stones from falling from the inside of the cylindrical collection tube during the removal process.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stone removal device in clinical hepatobiliary surgery. Background technique [0002] Hepatobiliary Surgery mainly studies hepatocellular carcinoma, hepatolithiasis, post-hepatitic cirrhosis and acute liver failure caused by severe hepatitis, which are major diseases that seriously threaten the health of Chinese people. Hepatolithiasis is a relatively common disease in hepatobiliary surgery. The current method is to cut the corresponding trachea to remove the stone. However, there are many disadvantages in the traditional operation. The treatment of gallstones is gradually carried out to minimally invasive surgery, but there is no minimally invasive device specially used for hepatolithiasis surgery. At present, the operation price of hepatolithiasis using minimally invasive methods is very expensive, and the operation is complicated and cumbersome, and the stone removal...

Hepatolithiasis is a relatively common disease in hepatobiliary surgery. The current method is to cut the corresponding trachea to remove the stone. However, there are many disadvantages in the traditional operation. The treatment of gallstones is gradually carried out to minimally invasive surgery, but there is no minimally invasive device specially used for hepatolithiasis surgery. At present, the operation price of hepatolithiasis using minimally invasive methods is very expensive, and the operation is complicated and cumbersome, and the stone removal effect is average.
