Puncture oriented adherent observation type puncture endoscope for percutaneous renal stone-extraction operation

Abstract

The invention relates to a puncture endoscope used for attached observation for puncturing and orientation in percutaneous nephrolithotomy, solving the technical problems of poor puncture accuracy, big amount of bleeding, high operation failure rate and poor safety of the existing appliances used in percutaneous nephrolithotomy. The puncture endoscope comprises a main endoscope body, an image transferring unit, a lighting unit, an ocular unit and a puncture body. The puncture body is composed of a puncture needle and an indwelling catheter. The ocular unit is composed of an ocular cover, an ocular lens and an ocular glass. The image transferring unit is composed of a multi-filament image transferring rod arranged inside a hollow outer tube of the puncture needle. The lighting unit is composed of a light beam collet which can be connected with the main endoscope body, a light beam interface which is arranged on the light beam collet and can be connected with an external light source, alight cone arranged inside the light beam interface, and a light transferring component which can transfer the external light source which passes through the light cone to the imaging surface of the multi-filament image transferring rod. The puncture body is fixedly arranged at the front end of the main endoscope body. The puncture endoscope has the advantages of good visibility during operations, high puncture accuracy, less bleeding, high operation success ratio and high safety and is unnecessary to be charged with water.

Description

technical field [0001] The invention relates to an endoscope for medical surgery, in particular to a puncture endoscope for percutaneous nephrolithotomy. Background technique [0002] Percutaneous nephrolithotomy is a new technology for the treatment of urinary calculi that has emerged in recent years. It uses special endoscopes, intracavitary lithotripsy and stone removal equipment to complete the treatment through percutaneous nephrostomy. As early as the 10th century in Arabia, there was a tradition of removing kidney stones through skin poking holes, but due to limited conditions and a low success rate, it has not been popularized and applied. It was not until the advent of percutaneous nephroscopy in the mid-1970s that this technology was relatively perfect and could be popularized and applied. my country introduced this technology and equipment from abroad in the early 1980s, first achieved success in Beijing, Guangzhou and other places, and then pushed it to the whol...
