Novel clinical calculus removing device for hepatobiliary surgery

Abstract

The invention discloses a novel clinical calculus removing device for hepatobiliary surgery, and particularly relates to the field of medical instruments. The novel clinical calculus removing device comprises a calculus storage part, a pair of calculus removing forceps is arranged at one end of the calculus storage part, and a connecting rod is arranged between the calculus storage part and the calculus removing forceps. The calculus storage part and the connecting rod are cooperatively used, so a medical worker pushes a second handheld rod to drive a first forceps head to be separated from asecond forceps head, and a transmission motor drives exhaust fan blades to rotate to generate accelerated airflow; and if the diameter of the clamped calculus is greater than the inner diameter of a main body tube, a user can push and pull back the second handheld rod in a reciprocating manner, calculi accommodated in a first accommodating groove and a second accommodating groove are crushed underthe acting force of a first wall breaking cone and a second wall breaking cone, the large-diameter calculi are crushed into a plurality of blocks, and calculi and calculus chips with reduced block diameters are recovered and accommodated into a storage cavity along with the accelerated air flow, large calculi can be crushed and taken out of the body through the device, and the effect of taking out the calculi can be achieved through a small incision.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically, the invention relates to a novel stone removal device used in clinical hepatobiliary surgery. Background technique [0002] Hepatolithiasis is a common and frequently-occurring disease, which refers to stones that occur in any part of the hepatobiliary system, including gallbladder stones, common bile duct stones, common hepatic duct stones, intrahepatic bile duct stones, and composite site stones. According to the chemical composition of stones, hepatolithiasis can be divided into cholesterol stones, pigment stones and mixed stones. The symptoms of gallbladder stones are not exactly the same, and some only show chronic indigestion, and may have belching, nausea, anorexia and mild upper abdominal pain. These symptoms are not specific, and many other diseases can have these symptoms. Such as gastric ulcer, gastric cancer, duodenal ulcer, chronic pancreatitis, e...

Problems solved by technology

[0003] At present, the most conventional and effective method for hepatic and gallstones is to use shell surgery to remove them. However, during the stone extraction operation, due to the different sizes and specifications of the stones, the incision should be made according to the size of the stones detected an
