Problems solved by technology
In the past, laparotomy, hepatic lobectomy, extrarenal lithotripsy, pyelolithotomy, and percutaneous renal lithotripsy were often used. In recent years, with the development of endoscopic surgery, percutaneous liver and renal surgery has become There are more and more percutaneous liver devices, but there are no percutaneous liver devices on the market, and percutaneous kidney devices have no scale markings, and the puncture is often too deep or too shallow, resulting in surgical failure, which affects the promotion and development of this technology

The invention relates to the technical field of medical auxiliary instruments and particularly relates to a safe ruler-guide percutaneous hepatorenal puncture expansion kit. The expansion kit comprises multiple expanders with hollow interiors, wherein the outer side walls of the expanders are provided with scales and scale values; the scales comprise long scales and short scales; four short scales are formed between two adjacent long scales; the distance between two adjacent long scales is 0.5cm; the distance between two adjacent short scales is 0.1cm; the scale values are formed on one side of the long scales, and one scale value is formed every two long scales from the front end of each expander. The outer side walls of the expanders are provided with the scales and the scale values, so that the puncture depth and position are definite; the safe ruler-guide percutaneous hepatorenal puncture expansion kit is simple in structure, economical and practical; by virtue of the safe ruler-guide percutaneous hepatorenal puncture expansion kit, related complications in a puncture process are reduced and the operation time is reduced.
Description
technical field [0001] The invention relates to the technical field of medical aids, in particular to a safe ruler-guided percutaneous liver-kidney puncture expansion set. Background technique [0002] Intrahepatic bile duct stones and kidney and ureter stones are common and frequently-occurring diseases in general surgery, and their treatment is extremely difficult. In the past, laparotomy, hepatic lobectomy, extrarenal lithotripsy, pyelolithotomy, and percutaneous renal lithotripsy were often used. In recent years, with the development of endoscopic surgery, percutaneous liver and renal surgery has become However, there are no percutaneous liver-specific devices on the market, and percutaneous kidney devices have no scale markings, and the puncture is often too deep or too shallow, resulting in surgical failure, which affects the promotion and development of this technology. Contents of the invention [0003] In order to overcome the disadvantages and deficiencies in th...
