Detailed Description

The present invention will be described in detail with reference to fig. 1, 2 and 3, and the illustrative embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.

The utility model provides a modular uretero-renoscope, including epitheca 2, can insert expansion cover core 1 in this epitheca, operation channel 12 has been seted up along the axial in the expansion cover core, but this operation channel embeds miniature nephroscope or seal wire etc. visual hole 13 of mountable endoscope is seted up along the axial in the expansion cover core. In the implementation process, the guide wire can pass through the operation channel, and the guide wire can be guided in a visible state through the endoscope and the visible hole, so that a clear visual field is provided for the expansion of the sheath core, the sheathing operation of the sheath is completed, and the ureter injury caused by blind insertion is avoided. In addition, the operating channel is internally provided with the miniature nephroscope, and the illuminating system of the miniature nephroscope can ensure the sheath to be operated under the visible state.

In the implementation process, the expansion sleeve core is also provided with a suction channel 14 along the axial direction, so that a three-channel visual expansion sleeve core is formed, waste liquid, slag and the like can be sucked out through the suction channel, and the guide wire is operated under a visual condition, so that the safety and the effectiveness are realized. Meanwhile, the sleeve core is placed under a visible condition, so that the operation is more convenient, and the operation time is saved. And a water injection channel 15 is also arranged in the expansion sleeve core along the axial direction, so that the clear visual field of the upper sheath can be kept. Therefore, the four-channel visible expansion sleeve core with the independent water injection channel is formed, and the operation is more convenient and time-saving. The front end of the expansion sleeve core extends out of the outer sheath, and the front end of the expansion sleeve core is conical, so that the guide expansion of the expansion sleeve core is facilitated; and the front end of the expansion sleeve core can be bent, and can be made of flexible materials, so that the sleeve core is further ensured to be safely and conveniently expanded.

The utility model discloses a can directly use surgical instruments such as miniature nephroscope 3 in the operation passageway of expansion cover core, because have optical imaging lighting system on the miniature nephroscope, the cone front end of expansion cover core can directly guide the expansion, and optical imaging lighting system can provide sufficient illumination, makes the accurate direction of expansion cover core to guarantee that the cover core expands under clear field of vision, avoid haring the ureter.
