Impact-during-suction surgical ureteroscope

A break-during-suction type surgical ureteroscope, comprising:

• a ureteroscope main body having a front end portion and a rear end portion, an operating portion operably coupled to the rear end portion of the ureteroscope main body, and a lithotripter;
• wherein the ureteroscope main body comprises a tube structure body, at least one perfusion channel in the tube structure body extending from the rear end portion to the front end portion, the at least one perfusion channel is provided with at least one perfusion opening located at the front end portion;
• and a suction channel in the tube structure body extending from the front end portion to the rear end portion, the suction channel is provided with a suction opening located at the front end portion;
• wherein the lithotripter is movably provided in the tube structure body and is capable of switching between a first state and a second state, when in the first state, a cutting head of the lithotripter extends out of the suction opening and is configured to break calculus, and when in the second state, the cutting head of the lithotripter retracts to the suction opening and is configured to break calculus blocked in the suction opening;
• wherein the ureteroscope main body further comprises a crushed calculus channel in communication with the suction channel, the lithotripter is telescopically located in the crushed calculus channel, and when the lithotripter is in the first state, the cutting head extends into the suction channel through the crushed calculus channel to extend out of the suction opening.
