Embodiment 1
[0041] A guided urethral protection expansion device, which is a guided urethral protection expansion device, including an expansion structure 2 sleeved on the front end of the urethroscope body 1 for guiding the urethroscope body 1 into the urethra; the expansion structure 2 and the urethroscope body 1 are detachably connected, and the expansion structure 2 can slide back and forth along the axial direction of the urethroscope body 1.
[0042] The expansion structure 2 includes two connecting parts 2-1 and two guiding parts 2-2; the two connecting parts 2-1 are detachably connected, and the two connecting parts 2-1 are snapped together. When the expanding structure 2 After the auxiliary urethroscope body 1 enters the urethra, the expansion structure 2 is conveniently removed from the urethroscope body 1 through the clamping effect between the two connecting parts 2-1, and it is not easy to hinder the follow-up inspection work of the urethroscope body 1 , the two connecting pa...
Embodiment 2
[0050] see Figure 1-7 , the number of mounting holes 2-1-2 is two groups, and the distance between the two groups of mounting holes 2-1-2 does not exceed 1.5cm; through the setting of two groups of mounting holes 2-1-2, when the second extrusion When the elastic soft sheets 2-1-5 deform and protrude the first elastic soft sheets 2-1-4, one group of the first elastic soft sheets 2-1-4 is located in the urethra, and the other group of first elastic soft sheets 2-1 -4 Located outside the urethra, the expansion structure 2 can be better fixed near the urethral opening, and it is not easy to cause the expansion structure 2 to enter the urethra too deeply due to misoperation, or the expansion structure 2 entering the urethra to slip out of the urethra due to misoperation outside.
Embodiment 3
[0052] see Figure 8 An elastic connection part 4 is fixed between the inner surface of the guide part 2-2 and the front end of the connection part 2-1. The elastic connection part 4 can be an elastic connection belt, and the elastic connection part 4 is used to limit the relative connection part of the guide part 2-2. The rotation angle of 2-1, through the setting of the elastic connecting part 4, when the urethroscope body 1 pushes forward to gradually push away the two guiding parts 2-2 that are close to each other, under the elastic force of the elastic connecting part 4, guide The part 2-2 is not easy to rotate around the connecting part 2-1 at an excessive angle and cannot return to its original position, or the distance between the two guiding parts 2-2 is too large due to the excessive rotation angle, and the expansion structure 2 cannot exit the urethra .
