Description
Technical Field
The invention relates to the field of medical instruments, in particular to a coaxial adjusting device of an air pressure trajectory lithotripsy system.
Background
Microchannel percutaneous nephrolithotripsy is the most common surgical approach in clinic.
The microchannel percutaneous nephroscope lithotripsy is a method for placing an air pressure ballistic lithotripsy rod into the lithotripsy position through a ureter hard mirror or a microchannel nephroscope, and is popular among the majority of urologists due to high efficiency, low side damage and low cost of the air pressure ballistic lithotripsy.
In percutaneous nephroscope lithotripsy, the left hand of an operator needs to constantly adjust the position of a tearing sheath, and the right hand holds the handle of a ureteroscope or a microchannel nephroscope and an air pressure ballistic lithotripsy rod. Because of the special mechanical construction of the ballistic gravel rod, the handles of the ballistic gravel rod and the pneumatic ballistic gravel rod must be kept in the same line during gravel crushing, otherwise the hand probe is easily broken. However, the lithotripsy probe rod is slender and the ballistic handle is heavy, so that it is difficult for the right hand of an operator to hold the ureteroscope or micro-channel nephroscope body while keeping the ballistic handle and the lithotripsy rod in the same straight line, and therefore the probe rod close to the handle and the handle are not in the same straight line at times in the actual use process, which results in low lithotripsy efficiency and bending and breaking of the probe rod.
