Problems solved by technology

[0003] The ureteroscope used in percutaneous nephrolithotomy has the following disadvantages. The soft mirror is easy to stay in the upper ureteral channel, and the hard mirror cannot be bent and turned at a large angle.
The pump tube used for cleaning in the existing operating equipment lacks a fixing mechanism, and the pump tube is easy to fall off, resulting in leakage of irrigation fluid

Abstract

The invention discloses an improved reclining lithotomy position percutaneous nephrolithotomy, which relates to medical instruments. The existing percutaneous nephroscopic surgery needs to change the surgical position, which leads to prolonged operation time, increased anesthesia risk, and labor intensity of medical staff. increase and decrease patient comfort. It includes the operating table, a set of percutaneous puncture and dilation equipment, ureteroscope, percutaneous nephroscope, cold light source, camera system, bedside B-ultrasound machine, intracavitary stone removal equipment, pressure-regulating water pump, and holmium laser.

Description

Technical field [0001] The present invention relates to medical equipment, in particular to an improved percutaneous nephrolithotomy in an oblique lying lithotomy position. Background technique [0002] At present, percutaneous nephrolithotomy (PCNL) has become the main treatment method for upper urinary tract stones, especially complex kidney stones (diameter ≧2.5cm). Surgical positions are mostly in prone and lateral positions, and a few are in supine position. All three surgical positions need to take the lithotomy position after anesthesia, and after indwelling the ureteral catheter and urinary tube, change to the corresponding position, re-sterilize and drape for the operation. The biggest advantage of the prone position is that the kidneys are relatively fixed and the puncture operation range is large. However, due to the patient's body gravity compressing the chest and abdomen, the lung capacity and the return blood volume decrease, which increases the risk of surgery, an...
