[0023] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] Embodiment 1:

[0025] Reference Figure 1 , is a ureteral endoscope disclosed in the present invention, comprising a tip portion 1, an insertion tube 2, an operating portion 3, and a connecting portion 4, wherein both ends of the insertion tube 2 are respectively connected to the tip portion 1 and the operating portion 3, one end of the connecting portion 4 is connected to the operating portion 3, and the other end is used to connect to a camera light source system, a working channel is provided in the insertion tube 2, a telescopic wire 5 is provided on the inner wall of the insertion tube 2, a front end of the telescopic wire 5 is fixed to the inner wall of the front end of the insertion tube 2, a rear end of the telescopic wire 5 passes through the rear end of the insertion tube 2 into the operating portion 3, and is connected to a direction control component in the operating portion 3.

[0026] In this embodiment, Figure 2 The direction control component includes a control part 6, a wiring part 7 and a guide part 8. The wiring part 7 is connected to the guide part 8, and the guide part 8 is connected to the control part 6. The rear end of the telescopic line 5 passes through the guide part 8 and is connected to the wiring part 7.

[0027] The control part 6 includes a base 61, a main gear 62 and a control rod 63. The base 61 is fixed in the operating part 3. A pin shaft 64 is fixed on the base 61. The main gear 62 is sleeved on the pin shaft 64. One end of the control rod 63 is fixed to the main gear 62, and the other end is located outside the operating part 3.

[0028] The wiring part 7 includes a first sub-gear 71 , which is installed in the operating part 3 and meshes with the main gear 62 . A wiring post 72 is disposed on the first sub-gear 71 , and the rear end of the telescopic wire 5 is connected to the wiring post 72 .

[0029] The guide portion 8 includes a second sub-gear 81 , which meshes with the first sub-gear 71 . A wire guide 82 is fixed to the second sub-gear 81 . The rear end of the telescopic wire 5 passes through the wire guide 82 and is connected to the terminal 72 .

[0030] In this embodiment, the guiding principle of the insertion tube 2 is that the direction of the tip 1 can be controlled by the wave control rod 63. When the control rod 63 is centered, the tip of the insertion tube 2 remains in a straight line; Figure 2 , the control lever 63 is moved backward, the main gear 62 drives the first sub-gear 71 to rotate, the position of the terminal 72 on the first sub-gear 71 changes, thereby pulling the telescopic wire 5, and the front end of the telescopic wire 5 pulls the front end of the insertion tube 2, so that the front end of the insertion tube 2 bends to one side; Figure 3 , the control rod 63 is moved forward, the main gear 62 drives the first sub-gear 71 to rotate in the opposite direction, and the position of the terminal 72 on the first sub-gear 71 is changed again, thereby pulling the telescopic wire 5, and the front end of the telescopic wire 5 pulls the front end of the insertion tube 2, so that the front end of the insertion tube 2 bends to the other side.

[0031] During this process, the wire guide 82 can guide the telescopic wire 5 and tighten the telescopic wire 5 to prevent the telescopic wire 5 from loosening, so that the telescopic wire 5 remains in a stressed state, thereby making the bending process of the front end of the insertion tube 2 smoother. Figure 2 In the embodiment, the telescopic wire 5 is passed through the upper part of the wire guide 82, passed through the lower part, and then connected to the terminal 72; Figure 3 In the process, as the control rod 63 fluctuates, the wire guide 82 rotates 180°, the telescopic wire 5 passes through the lower part of the wire guide 82, passes through the upper part, and then connects to the terminal 72; during the whole process, the telescopic wire 5 always remains in a taut state.

[0032] In this embodiment, Figure 4 The front end of the insertion tube 2 has a portion of a flexible tube 21, and the two ends of the flexible tube 21 are two joints 22, one joint 22 is connected to the front end 1, and the other joint 22 is connected to the soft conduit 23 of the insertion tube 2. The material of the telescopic wire 5 can be steel wire, and the front end of the telescopic wire 5 is welded and fixed to the flexible tube 21. Both are metal, and the welding fixing effect is good. When the insertion tube 2 is pulled, the two are not easy to fall off.

The instrument (such as a grasping forceps) enters the operating part 3 from the instrument external working channel 31, passes through the operating part 3 and the insertion tube 2 in turn, and passes out from the distal end 1 into the body to perform surgery.

[0034] In this embodiment, the front end of the optical fiber channel 92 is connected to the tip portion 1, and the rear end sequentially passes through the insertion tube 2, the operating portion 3 and the connecting portion 4. The front end of the light guide is connected to the tip portion 1, and the rear end enters the optical fiber channel 92, and is connected to the imaging light source system from the connecting portion 4.

[0035] In this embodiment, the front end of the imaging line channel 93 is connected to the distal end 1, and the rear end sequentially passes through the insertion tube 2, the operating part 3 and the connecting part 4. The front end of the imaging line is connected to the distal end 1, and the rear end enters the optical fiber channel 92, and is connected to the imaging light source system from the connecting part 4.

[0036] In this embodiment, the tip end 1 is a transparent cover body, which is covered on the front end of the insertion tube 2. A light source point 11 and a camera point 12 are provided on the tip end 1. The front end of the light guide beam abuts on the light source point 11, and the light can be transmitted through the tip end 1 to illuminate the surgical site. The camera abuts on the camera point 12 to take pictures of the surgical site.

[0037] A channel outlet 13 is also provided on the distal end portion 1 , and the channel outlet 13 is communicated with the instrument channel 91 , and the instrument passes through the channel outlet 13 and enters the surgical site.

[0038] In this embodiment, the tip portion 1 and the insertion tube 2 of the ureteral endoscope are disposable, which can ensure that the patient will not be cross-infected.
