A kind of hepatobiliary stone extraction tool

Abstract

The invention relates to the technical field of medical devices, in particular to a stone dislodger used for a hepatology department. The stone dislodger includes a shell, a micro pump, an agent box and a control main board. The bottom of the shell is provided with a plugged tube. A sealing plate and a shell inner cavity formed above the sealing plate forms a crushed stone collection chamber, the inside of the plugged tube is divided into a liquid absorption channel and a liquid return channel through a partition, the shell located on the lower portion of the sealing plate is internally provided with the micro pump and the agent box, a stone feeding structure and a stone filtering structure are arranged on the sealing plate, and the input end and output end of the micro pump are connected correspondingly with the liquid return channel and the stone filtering structure respectively, and the control main board is embedded into the outer wall of the shell and electrically connected with the micro pump. The structure is simple, operation is easy, when crushed stones are taken from the bile duct, the plugged tube is inserted only by forming a tiny operation opening, the damage to the liver and the bile duct can be reduced to the maximum extent, and thus convenience is brought to the operation of doctors.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stone removal tool for hepatobiliary department. Background technique [0002] Intrahepatic bile duct stones are one of the common diseases in the hepatobiliary department. The most effective way to treat intrahepatic bile duct stones is to take out the stones. In order to take out the stones, it is often necessary to use stone removal equipment. [0003] In the prior art, such as a hepatobiliary lithotomy device with authorization notification number CN208287047U, a new type of stone removal device for clinical hepatobiliary surgery with application publication number CN108720896A, a lengthened biliary stone removal forceps with authorization notification number CN207996226U, etc. , it generally adopts two interlocking and clamping rods or covers to clamp the stones, so as to take out the stones, but the above-mentioned schemes only consider the direct removal of stone...
