Attaching observation type puncture endoscope for percutaneous nephrolithotomy

Abstract

The invention relates to an attached observation type endoscope for percutaneous nephrolithotomy, which solves the technical problems of excessive bleeding, higher failure rate of the operation and low safety of the equipment used in the percutaneous nephrolithotomy. The endoscope comprises a main body, an image transfer unit, a lighting unit, an ocular unit and a puncture body; the puncture body comprises a puncture needle and a catheter; the puncture needle comprises a hollow outer pipe; the ocular unit comprises a ocular cover, a reversed image lens, an ocular lens and ocular glass; the image transfer unit comprises a multifilament image transfer rod arranged in the hollow outer pipe of the puncture needle; the lighting unit comprises a light beam grip connected with the main body, a light beam interface arranged on the light beam and connected with an external light source, a light cone arranged in the light beam interface and a light transfer optical fiber bundle connected with an image output surface of the multifilament image transfer rod; and black epoxy resin glue is filled in the outer circumference of an imaging surface of the multifilament image transfer rod. The endoscope has the advantages of good operational visibility, less bleeding, higher operational success rate, high safety and unnecessary water flushing.

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-1940s 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...
