[0022] The end of the adjusting disc 7 is provided with a collecting pipe 11, the suction channel and the water inlet channel are located in the inside of the collecting pipe 11, and the three-way valve 12 for controlling the suction channel and the water inlet channel is arranged on the collecting pipe 11, the top of the adjusting disc 7 is provided with a wiring end two 10, the camera wire core and the illumination wire core are located in the inside of the wiring end two 10, the wiring end two 10 is connected with the external control instrument through the first lead wire, the operating handle 1 is provided with a wiring end one 6, the temperature and pressure wire core is located in the inside of the wiring end one 6, the wiring end one 6 is connected with the external monitoring instrument through the second lead wire.

[0023] The end of the operating handle 1 is provided with the adjusting disc 7, the side of the adjusting disc 7 is provided with a scale 8, the adjusting disc 7 is rotatably provided with an adjusting rod 9, the adjusting rod 9 is connected with the curved tube 4 through the tensile steel wire located in the inside of the operating handle 1, the hose handle 2 and the hard sheath tube 3.

[0024] When using the disposable electronic ureteral nephroscopic multi-lumen catheter, the imaging module 14 and the LED lamp source 13 are turned on through the external control instrument, the curved tube 4 and the tip 5 are stretched into the renal pelvis, at this time, the adjusting rod 9 is rotated, the bending direction of the curved tube 4 is controlled through the tensile steel wire, the bending direction and the bending degree of the curved tube 4 are adjusted through the scale 8, so as to facilitate the imaging module 14 on the tip 5 to observe the environment in the renal pelvis without dead angle, and then the position of the stone is quickly found.

[0025] After the location of the stone is found, the stone is crushed by holmium laser or thulium laser, and then the crushed stone is taken out by a stone basket under the observation of the imaging module 14. After the stone is taken out, the ureteral nephroscope is pulled out and then inserted again to take out another stone. The operation is repeated until the stones are completely removed.

[0026] In order to avoid the influence of the turbidity of the environment in the renal pelvis on the operation of the imaging module 14, the suction channel and the water inlet channel are controlled by the three-way valve 12, so that the water circulates in the suction channel, the water inlet channel and the renal pelvis, thereby maintaining the clarity of the environment in the renal pelvis, and facilitating clear imaging of the imaging module 14.

[0027] Since the monitoring groove 17 is formed on the side of the end 5, and the temperature and pressure sensor 18 is located in the monitoring groove 17, the temperature and pressure sensor 18 can achieve the closest monitoring distance in the renal pelvis, thereby accurately monitoring the pressure and temperature in the renal pelvis, and transmitting the monitoring data to the external monitoring instrument through the temperature and pressure wire core and the second wire, so that the external monitoring instrument can monitor the pressure and temperature in the renal pelvis, and the operation can be completed smoothly, perfectly and safely. The problem that the pressure measured by the existing electronic ureteral nephroscopy multi-lumen catheter cannot truly reflect the pressure in the renal pelvis, and the surgery cannot be completed smoothly, perfectly and safely is solved.

[0028] Specifically, if the pressure monitored by the temperature and pressure sensor 18 is too large, the external monitoring instrument alarms to prompt medical staff to absorb the liquid in the renal pelvis through the suction port 15 and the suction channel to reduce the pressure, and if the pressure is too small, the liquid in the renal pelvis is supplemented through the water inlet 16 and the water inlet channel to increase the pressure. Thus, the present one-time electronic ureteral nephroscopy multi-lumen catheter realizes integrated irrigation.

[0029] When the temperature in the renal pelvis is too high, the holmium laser or thulium laser crushing operation is stopped, thereby protecting the patient's organs from being damaged and avoiding medical accidents.
