Abstract

The invention discloses a stone removal device for hepatological surgery department. The stone removal device comprises a moving box body, a drainage tank and a physiological saline tank are installedinside the moving box body, the drainage tank is connected to a negative pressure gas pump, the drainage tank is also connected to a drainage electric control valve, the physiological saline tank isconnected to a pressurized gas pump, the physiological saline tank is also connected to a cleaning electric control valve, a carbon dioxide gas treatment box is also installed inside the moving box body, the upper end of the carbon dioxide gas treatment box is connected to a gas intake pump through a second electronic control valve, the gas intake pump is connected to a gas outlet control valve, acontrol box is installed at the upper end of the moving box body, and a display screen and a control keyboard are installed at the upper end of the control box. The stone removal device is used for removing all gallstones in a gallbladder under the direct vision of a fiber choledochoscope, can achieve the functions of negative pressure drainage, physiological saline cleaning and tissue bulging bycarbon dioxide, greatly facilitates the stone removal work, improves the surgical efficiency of medical staff, facilitates the surgery, greatly reduces the preparation time and workload of the medical staff, provides a patient with good medical experience and is conducive to disease rehabilitation.

Description

technical field [0001] The invention relates to a medical device, in particular to a stone removal device and method for hepatobiliary surgery. Background technique [0002] A solid mass formed in the lumen of a duct or in a lumen of a luminal organ (such as the kidney, ureter, gallbladder, or bladder, etc.) in a human or animal body. It is mainly found in the gallbladder, bladder, and renal pelvis, and can also be found in the lumens of pancreatic ducts and salivary ducts. Stones are composed of inorganic salts or organic matter. There is generally a core in the stone, which is composed of exfoliated epithelial cells, bacterial masses, parasite eggs or worms, fecal matter or foreign matter, and inorganic salts or organic matter are deposited on the core layer by layer. Due to the different organs involved, the stone formation mechanism contains different components, shapes, textures, and effects on the body. In general, stones can cause luminal obstruction, affect the dr...

Problems solved by technology

Due to the environmental pollution in the process of social development and the lack of safety of people's drinking water and diet, there are more and more patients with gallbladder stones in hospital patients. In the face of diverse patients and different disease manifestations, traditional gallbladder stone equipment can no longer meet the requirements. The needs of hospitals and patients, and now there are few stone treatment equipment, especially for the treatment of gallbladder stones, stone removal medical equipment is relatively rare, single-function, complicated operation, can not provide good treatment for patients, and patients have poor treatment experience
