Problems solved by technology

However, the lithotripsy probe is slender and the ballistic handle is thick and heavy. It is difficult for the right hand of the operator to grasp the body of the ureteroscope or microchannel nephroscope while keeping the ballistic handle and the lithotripsy rod in the same straight line. From time to time, the probe rod near the handle is not in the same straight line as the handle, resulting in low stone crushing efficiency and bending and breaking of the probe rod

Abstract

The invention discloses a coaxial adjusting device of an air pressure ballistic lithotripsy system. The coaxial adjusting device comprises a first fixing piece, a second fixing piece, a fixing rod andan adjusting mechanism. One end of the first fixing piece is installed on the fixing rod, and the other end of the first fixing piece is detachably installed on a handle of an air pressure ballisticlithotripsy rod. One end of the second fixing piece is installed on the fixing rod, and the other end of the second fixing piece is detachably installed on a ureteroscope or a micro-channel nephroscope. The adjusting mechanism drives the fixing rod to rotate within an angle range. The air pressure ballistic lithotripsy rod and the ureteroscope or the micro-channel nephroscope can be located on a same axis all the time.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a coaxial adjustment device for a pneumatic ballistic lithotripsy system. Background technique [0002] Microchannel percutaneous nephrolithotomy is the most common surgical procedure in clinical practice. [0003] Micro-channel percutaneous nephrotripsy is to place pneumatic lithotripsy rods through ureteroscopes or micro-channel nephroscopes into the lithotripsy. Due to the high efficiency, low secondary damage and low cost of pneumatic ballistic lithotripsy, it is widely accepted by urologists. Doctor's favor. [0004] In percutaneous nephrolithotomy, the operator's left hand needs to constantly adjust the position of the tearing sheath, and the right hand holds the handle of the rigid ureteroscope or microchannel nephroscope or the pneumatic ballistic lithotripsy rod. Because of the special mechanical structure of the ballistic lithotripsy rod, the handles of the ballistic ...
