Negative-pressure suction biliary tract stone extraction assistance device

Abstract

The invention discloses a negative-pressure suction biliary tract stone extraction assistance device. The device comprises a handle and an auxiliary pipe, wherein the upper end of an inner cavity of the handle is provided with a first reserved groove, and an inner cavity of the first reserved groove sleeves the auxiliary pipe; an inner cavity of the auxiliary pipe is provided with an adjusting steel wire and a tube, and the right side of the auxiliary pipe is fixedly connected with a clamping plate; the right side of the clamping plate is fixedly connected with a clamping plate, and the innerside of the clamping plate is provided with an airbag; one side of the right side of the auxiliary pipe is provided with an illuminating lamp, and the other side of the right side of the auxiliary pipe is provided with a camera; the middle end of the left side of the inner cavity of the first reserved groove is fixedly connected with an electric retractable rod, and the right side of the electricretractable rod is fixedly connected with the left side of the adjusting steel wire; meanwhile, the right side of the adjusting steel wire is also connected with the clamping plate, and the lower endof the inner cavity of the handle is provided with a second reserved groove. The airbag is arranged on the inner side of the clamping plate, and the effect of efficiently extracting stones can be achieved through the effects of the tube, a draught fan, the electric retractable rod and the adjusting steel wire.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a negative pressure suction biliary tract stone extraction auxiliary device. Background technique [0002] Biliary stones are a common disease in surgery. Stones in the common bile duct can cause biliary obstruction secondary to jaundice, cholangitis and even pancreatitis, which is life-threatening. Surgery is the only way to treat this disease. Choledochoscopic stone removal is currently the most commonly used surgical treatment for biliary stones. A kind of method, in this process, usually place the fiber choledochoscope along the biliary incision, after discovering the stone, use the stone removal net to take out the stone, but the stone removal effect of the prior art is not ideal, thus resulting in long operation time, causing harm to the patient Therefore, we propose a negative pressure suction device for biliary stone extraction.
