Referring to fig. 1-3, a ureteral sheath comprises a sheath tube 1, a guiding tube 2, a sheath tube joint 3 and a guiding joint 4; the guiding tube 2 is sleeved in the sheath tube 1, the sheath tube 1 is fixedly connected with the sheath tube joint 3, and the sheath tube 1 is communicated with the sheath tube joint 3; the guide pipe 2 is fixedly connected with the guide joint 4, and the guide joint 4 is detachably connected with the sheath pipe joint 3; the sheath tube joint 3 comprises a first connecting tube portion 301, a second connecting tube portion 302 and a third connecting tube portion 303 which are communicated, the second connecting tube portion 302 and the third connecting tube portion 303 are respectively located at two sides of the first connecting tube portion 301, a luer lock joint 3021 is arranged at the end of the second connecting tube portion 302, a pagoda joint 3031 is arranged at the end of the third connecting tube portion 303, and a negative pressure hole 3032 is formed in the third connecting tube portion 303.

In this embodiment, the working principle of the ureteral sheath is: the guiding tube 2 plays a guiding role to drive the sheath tube 1 to be inserted from the genital organ of the patient together, and the fact that the sheath tube 1 is difficult to be directly inserted from the genital organ of the patient because the outer diameter of the sheath tube 1 is large needs to be described, and the guiding tube 2 is needed to drive the sheath tube 1 to be inserted from the genital organ of the patient together; when the sheath tube 1 is inserted to the corresponding position, the guide joint 4 is unscrewed, the guide joint 4 and the guide tube 2 are pulled out together, the sheath tube joint 3 has three connecting tube parts in total, wherein the first connecting tube part 301 is used for inserting an electronic mirror with internal fire laser, and the first connecting tube part 301 can be also inserted into a ureteral stent or other devices; the second connection tube 302 is mainly used as backup, and it is specifically described that the electronic mirrors with fire laser built in are numerous in the market at present, some of the electronic mirrors with fire laser built in have water injection function, and other electronic mirrors with fire laser built in do not have water injection function, when the electronic mirrors with fire laser built in do not have water injection function are used, it is necessary to connect a fluid pump to the second connection tube 302 externally, and the luer lock connector 3021 is arranged at the end of the second connection tube 302, which is for connecting the fluid pump, of course, according to the actual requirement of the operation, the second connection tube 302 can also be connected with other medical devices, which is not exemplified herein; the third connecting pipe portion 303 is used for connecting a negative pressure suction device, wherein, the end of the third connecting pipe portion 303 is provided with a pagoda joint 3031, the effect is that the third connecting pipe portion 303 is connected with the negative pressure suction device, what needs to be specifically explained here is that the third connecting pipe portion 303 is provided with a negative pressure hole 3032, in the process of operation, the negative pressure suction device is not required to be opened directly when the negative pressure suction device is required to work, the negative pressure suction device is not required to be closed when the negative pressure is not required to work, because the negative pressure suction device is a bit away from an operating table, the operation is obviously complicated, and the frequent switching of the negative pressure suction device has a certain influence on the service life of the negative pressure suction device, therefore, by arranging the negative pressure hole 3032 on the third connecting pipe portion 303, the negative pressure suction device can be always opened when the negative pressure is required to work, a doctor can hold the negative pressure hole 3032 by hand, and when the negative pressure is not required to work, the doctor can hold the finger of the negative pressure hole 3032, and the operation is very simple and convenient.

Further, a transit joint 5 is further provided between the sheath tube joint 3 and the guide joint 4, the first connecting tube 301 is detachably connected with the transit joint 5, the guide joint 4 is detachably connected with the transit joint 5, a circular hole is provided in the transit joint 5, and the diameter of the circular hole is smaller than that of the inner hole of the first connecting tube 301.

Further, a rubber sealing ring 6 is disposed between the transit joint 5 and the end of the first connecting pipe 301.

In the present embodiment, by providing the transit joint 5, and the diameter of the circular hole in the transit joint 5 is smaller than the diameter of the inner hole of the first connecting pipe portion 301, the purpose is that the electronic mirror can completely block the rubber seal 6 after the electronic mirror is inserted, and the water in the sheath pipe 1 can be prevented from flowing back from the first connecting pipe portion 301.

Further, a first anti-slip pattern 501 is provided on the peripheral surface of the transit joint 5.

Further, the end of the guiding tube 2 away from the guiding joint 4 extends out of the sheath tube 1, and the end of the guiding tube 2 is provided with a pointed tip.

In this embodiment, insertion of the tip of the guide tube 2 from within the reproductive organ of the patient is facilitated by providing the tip of the guide tube 2.

Further, a pair of hand-held rings 304 are provided on the sheath tube joint 3, and a second anti-slip pattern 305 is provided on the circumferential surface of the sheath tube joint 3.

In this embodiment, by providing a pair of hand-held rings 304, it is convenient for a doctor to hold the guide joint 4 by hand with the hand-held rings 304, and when in actual use, the index finger and middle finger of the doctor are respectively inserted into one of the hand-held rings 304.

Further, a third anti-slip pattern 401 is provided on the circumferential surface of the guide joint 4.
