Novel clinical calculus removing device for hepatobiliary surgery

Abstract

The invention discloses a novel clinical calculus removing device for hepatobiliary surgery. The device comprises a handle assembly, the two ends of the handle assembly are connected with a push rod and a rubber tube respectively, a fixing cylinder is fixedly sleeved with one end in the rubber tube, a fixing frame is fixedly installed in the fixing cylinder, an expansion mechanism is fixedly installed on the fixing frame, and the expansion mechanism comprises a fixing tube; an adjusting groove is formed in the outer side of the fixing tube, an adjusting ring is slidably mounted on the adjusting groove, a plurality of supporting rods are fixedly mounted on the side face of the adjusting ring through shafts, a fixing head is fixedly mounted at the end, away from the fixing frame, of the fixing tube, and a plurality of adjusting rods are fixedly connected to the side face of the fixing head through shafts and correspond to the supporting rods one to one. The adjusting rods are in one-to-one correspondence with the supporting rods. And the adjusting rods are fixedly connected with one sides of the middle sections of the supporting rods through shafts. The novel clinical calculus removing device for the hepatobiliary surgery department is simple and reasonable in structure, novel in design, easy to operate, capable of effectively improving the removing efficiency of stones in the hepatobiliary surgery department and improving the progress efficiency of the surgery, and high in practical value and popularization significance.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a novel stone removal device for clinical use in hepatobiliary surgery. Background technique [0002] At present, the stone extraction in hepatobiliary surgery is mainly carried out through the stone extraction basket, which is widely used in the treatment of stones in different surgical fields such as urology and biliary tract. The stone extraction basket is also a surgical instrument often used in hard mirror gallstone extraction . [0003] At present, when the existing stone removal device is in use, the stones in the mesh basket wire need to be dragged and transported after the stone is taken out by the wire basket. However, some stones are not high in hardness and are prone to breakage when dragged in the bile duct. , from the situation where the mesh basket wire falls off, the medical staff needs to pick up the broken stones again, which prolongs the operation time...

Problems solved by technology

[0003] At present, when the existing stone removal device is in use, the stones in the mesh basket wire need to be dragged and transported after the stone is taken out by the wire basket. However, some stones are not high in hardness and are prone to breakage when dragged in the bile duct. , from the situation where the mesh basket wire falls off, the medical staff needs to pick up the broken stones again, which prolongs the operation time of the operation and increases the difficulty of the operation for the medical staff in the stone removal operation. Therefore, we make improvements and propose A new type of stone removal device for clinical use in hepatobiliary surgery
