[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1 The utility model provides a technical solution for a ureteral endoscope with monitoring: a ureteral endoscope with monitoring, comprising an introduction sheath 1, the rear end of the introduction sheath 1 is rotatably connected to an operating handle 2, the rear end of the introduction sheath 1 extends into the interior of the operating handle 2, and the front top of the operating handle 2 is rotatably connected to a mobile monitoring screen 3, the mobile monitoring screen 3 can be adjusted in angle according to the needs of the operator to obtain the best observation angle, the middle top of the operating handle 2 is fixedly connected to a rotating fixing component 4, which is used to play a role when the rotation angle of the introduction sheath 1 needs to be adjusted, wherein the introduction sheath 1 can penetrate deep into the ureter to monitor through the camera and can perform stone removal through this component, which is a prior art and will not be explained here.

[0024] See also Figure 2The mobile monitoring screen 3 includes a rotating shaft 34, which is rotatably connected to the upper inner side of the operating handle 2. A multi-stage snap column 32 is fixed to the outer surface of the rotating shaft 34. When the rotating shaft 34 rotates, it will drive the multi-stage snap column 32 to rotate together. At the same time, the rotation of the rotating shaft 34 has a large damping feeling, which can support other components. The end of the multi-stage snap column 32 away from the rotating shaft 34 is fixedly connected to the limiting column 31, which can prevent the mobile monitoring component 33 from slipping off the multi-stage snap column 32. The outer surface of the multi-stage snap column 32 is slidably connected to the mobile monitoring component 33, and the mobile monitoring component 33 can slide along the multi-stage snap column 32 to achieve position adjustment.

[0025] See also Figure 2 The side of the multi-stage buckle column 32 close to the operating handle 2 is a wave-shaped buckle groove, which can increase the friction and stability of the buckle.

[0026] See also Figure 3 The mobile monitoring component 33 includes a support plate 336, and the left and right ends of the support plate 336 near the limit column 31 are fixedly connected to the rotating column 333, and the outer surface of the rotating column 333 is rotatably connected to the rotating support block 332, and the rotating support block 332 can rotate around the rotating column 333. The two rotating support blocks 332 are jointly fixedly connected to the monitoring display screen 331 on the side away from the support plate 336. The angle of the monitoring display screen 331 can be adjusted by rotating the rotating support block 332. The support plate 336 is fixedly connected to the four outward corners of the monitoring display screen 331, which supports and stabilizes the entire mobile monitoring component 33 and provides space for the movement of the mobile monitoring component 33. The four support columns 334 are jointly fixedly connected to the polyethylene snap plate 335 on the end away from the support plate 336.

[0027] See also Figure 2 and Figure 3 The polyethylene snap plate 335 is provided with a wavy snap groove identical to the multi-stage snap column 32 on one side close to the support plate 336 , which can engage with the multi-stage snap column 32 , and the multi-stage snap column 32 passes through the support columns 334 front and back.

[0028] When the position of the mobile monitoring component 33 needs to be fixed, the mobile monitoring component 33 is pushed toward the multi-stage snap column 32. Due to the wavy shape of the snap grooves, they will engage with the surface of the multi-stage snap column 32, providing a certain resistance and stability, thereby fixing the mobile monitoring component 33 in the desired position. The polyethylene material of the polyethylene snap plate 335 has a certain elasticity and ductility, and can be deformed during movement, and rebound to be fixed when it moves to engage with the multi-stage snap column 32.

[0029] See also Figure 4The rotation fixing component 4 includes a driven bevel gear 44, the middle part of the driven bevel gear 44 is fixedly connected to the outer surface of the introduction sheath 1 and the inner part of the operating handle 2, the upper side of the driven bevel gear 44 is meshed with the active bevel gear 43, the top of the active bevel gear 43 is fixedly connected to the rotating knob 42, the top of the rotating knob 42 extends to the top of the operating handle 2, and the rotating knob 42 is provided with a rotation fixing component 41 at the rear outside of the operating handle 2. The top of the rotating knob 42 is a groove knob, and the outer surface of the rotating knob 42 is rotatably connected to the top of the operating handle 2.

[0030] When the rotation angle of the introduction sheath 1 needs to be adjusted, the rotation knob 42 is rotated. The rotation of the rotation knob 42 drives the active bevel gear 43 fixedly connected to the bottom thereof to rotate. Since the active bevel gear 43 is meshed with the driven bevel gear 44, the rotation of the active bevel gear 43 drives the driven bevel gear 44 to rotate, and the rotation of the driven bevel gear 44 realizes the rotation of the introduction sheath 1.

[0031] See also Figure 5 The rotating fixing assembly 41 includes a supporting rotating block 413, the bottom end of the supporting rotating block 413 is fixedly connected to the top of the operating handle 2, the middle part of the supporting rotating block 413 is rotatably connected to a rotating connecting column 412, and the end of the rotating connecting column 412 away from the supporting rotating block 413 is fixedly connected to a fixing ring 411, and the fixing ring 411 is engaged with the groove at the top of the rotating knob 42.

[0032] The support rotating block 413 is fixed to the top of the operating handle 2, providing stable support for the rotating connecting column 412. The rotating connecting column 412 can rotate in the middle of the support rotating block 413, so that the connected fixing ring 411 can perform a flip-up action. When the rotating knob 42 needs to be fixed, the fixing ring 411 is rotated to a position engaged with the groove at the top of the rotating knob 42. Since the fixing ring 411 and the groove at the top of the rotating knob 42 cooperate with each other, the rotation of the rotating knob 42 is restricted, thereby achieving the fixation of the rotating knob 42.

[0033] Working principle:

[0034] First, adjust the mobile monitoring screen 3. The rotating shaft 34 can realize horizontal angle adjustment. The multi-stage buckle column 32 and the mobile monitoring component 33 can cooperate to realize the change of the front and rear position and vertical angle to obtain the best observation angle. Then insert the introduction sheath 1 into the patient's ureter. The operating handle 2 is used to control the direction and depth of insertion. When the rotation angle of the introduction sheath 1 needs to be adjusted, rotate the rotating knob 42. After adjusting to the appropriate angle, engage the fixing ring 411 in the rotating fixing component 41 with the groove at the top of the rotating knob 42 to fix the rotating knob 42 to ensure that the angle of the introduction sheath 1 is stable.

[0035] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
