Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1

[0030] See also Figure 1-Figure 3 and Figure 5 In order to solve the problem that the device is blocked by the internal tissue during use and affects the normal use, the present embodiment provides the following technical solutions, wherein a spreading mechanism is provided, and the tissues in the patient's body (including irregularly growing tumor tissue) are spread out by the spreading mechanism to avoid blocking the normal operation of the doctor. Specifically disclosed is: a handheld component 1 with a cylindrical structure, a mirror sheath barrel 2 with a strip structure is installed at the front end of the handheld component 1, and holding handles 3 are fixedly installed on the left and right sides of the handheld component 1, an endoscope 4 is fixedly installed inside the handheld component 1 and is connected to an observation eyepiece 5 fixedly installed on the outside of the rear end of the handheld component 1, and the handheld component 1 and the mirror sheath barrel 2 are connected to each other by a connecting piece 6, and the connecting piece 6 is connected to the mirror sheath barrel The endoscope 4 is fixedly connected to the body 2, and an expansion mechanism is installed at the front end of the sheath barrel 2, which is used to expand the patient's body tissue, and an adjustment mechanism is installed inside the sheath barrel 2, which is used to change the angle of the endoscope 4, the expansion mechanism includes an expansion plate 7 symmetrically rotatably installed at the front end of the sheath barrel 2, and a reset spring 10 is fixedly installed between the expansion plates 7 on the upper and lower sides, a connecting rope 8 is fixedly installed on the outer surface of the expansion plate 7, and the connecting rope 8 is slidably connected to a limit block 801 fixedly installed on the outer surface of the sheath barrel 2, the lower end of the connecting rope 8 is wound around the outside of the winding column 9, and the winding column 9 is rotatably connected to the connecting piece 6, and the connecting piece 6 and the hand-held component 1 form a disassembly and installation structure through a thread.

[0031] When using the device, first pass the endoscope 4 through the connecting piece 6 and threadedly install it on the outside of the connecting piece 6 (at this time, the endoscope 4 penetrates into the interior of the scope tube 2), and then the doctor inserts the scope tube 2 into the patient's bladder by holding the handle 3. At the same time, the doctor observes the internal situation of the patient's bladder through the external observation eyepiece 5 in conjunction with the endoscope 4. When encountering an operation where the patient's body tissue is blocked, the doctor rotates the winding column 9 at the corresponding position, and uses the winding column 9 to wind up the connecting rope 8 (at this time, the connecting rope 8 slides relative to the limit block 801), so that the connecting rope 8 pulls the expansion plate 7. At this time, the expansion plate 7 opens to stretch the blocked tissue to avoid affecting the doctor's normal operation. After releasing the pull, the expansion plate 7 is reset under the pulling action of the reset spring 10.

[0032] Embodiment 2

[0033] See also Figure 3 and Figure 4In order to solve the problem that the angle of the endoscope 4 is uncertain and the observation range is small during use of the device, this embodiment provides the following technical solutions: an adjustment mechanism is set to change the angle of the endoscope 4 through the adjustment mechanism, thereby expanding the overall observation range of the endoscope 4 and making it more convenient for doctors to operate. Specifically, it is disclosed that: the adjustment mechanism includes an adjustment airbag 11 fixedly installed inside the front end of the scope sheath barrel 2, and a connecting hose 12 is fixedly installed on the outside of the adjustment airbag 11, and a connecting hose 12 and an active airbag 13 fixedly installed on the outside of the connecting piece 6 form a connecting structure, and an extrusion plate 14 is fixedly installed on the outer surface of the active airbag 13.

[0034] During the operation, the doctor presses the squeezing plate 14 at the corresponding position, so that the squeezing plate 14 squeezes the active airbag 13. At this time, the air inside the active airbag 13 enters the adjusting airbag 11 through the connecting hose 12, so that the adjusting airbag 11 squeezes the front end of the endoscope 4, thereby changing the angle of the endoscope 4 and expanding the overall observation range.

[0035] Embodiment 3
