Hepatobiliary surgery calculus taking-out device

Abstract

The invention discloses a hepatobiliary surgery calculus taking-out device. The hepatobiliary surgery calculus taking-out device comprises a sheathing canal, a net rope is arranged in the sheathing canal, the two ends of the net rope extend to the outer side of the sheathing canal, and a handle mechanism connected with the net rope is arranged at the tail of the sheathing canal; a basket net is arranged at the front end of the net rope, and a pressing part used for assisting the basket net in crushing calculus is arranged at the end, close to the basket net, of the net rope. Different from the prior art, the hepatobiliary surgery calculus taking-out device has the advantages that in the actual taking-out process of the calculus in the hepatobiliary surgery, especially for large and hard calculus, the pressurizing part can be ejected out of the sheathing canal and is in contact with the calculus by utilizing the net rope, so that a pressurizing mechanism is used for pressurizing to assist calculus crushing in the calculus crushing process of the net basket, the calculus crushing capacity of the calculus taking net basket is effectively improved, and efficient taking and use of the hepatobiliary calculus are guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a device for taking out stones in hepatobiliary surgery. Background technique [0002] Stones are solid lumps formed in the duct lumen or luminal organs (such as kidney, ureter, gallbladder or bladder, etc.) in the human or animal body. They are mainly found in the gallbladder, bladder and renal pelvis, and can also be found in the pancreatic duct, The lumen of the salivary duct, etc., is composed of inorganic salts or organic matter. There is usually a core in the stone, which is composed of exfoliated epithelial cells, bacterial masses, parasite eggs or worms, fecal matter or foreign matter, and the inorganic salts or organic matter are re-layered. On the core of layer deposition, due to the different organs involved, the mechanism of stone formation contains different components, shapes, textures, and effects on the body. In general, stones can cause lumin...

Problems solved by technology

[0005] However, for the currently most commonly used fast-breaking one-piece basket structure, when it encounters larger and harder stones during clinical operations, since the basket core is composed of a basket wire (titanium-nickel alloy) and a pulling wire ( 304 medical stainless steel), although it has good tensile strength and toughness, but there is also a limit, affected by the hardness of the stone, in the process of continuous tightening of the basket wire at any time, the basket is already protected before the stone is broken. broken, resulting in poor stone crushing ability, which affects the removal and use of stones. In addition, when taking out broken stones, sharp beveled edges will be broken to varying degrees during the stone fragmentation process, and the existing mesh basket is for It is convenient for stones to be inserted into the basket and the distance between the adjacent mesh wires is relatively large, which may easily cause sharp stones to scratch the intestinal tract or sores when they are taken out, causing unnecessary damage to patients. For this reason, we propose a Stone removal device for hepatobiliary surgery
