It is a pair of slender tubes, showing a flat cylindrical shape, with an average inner diameter of 0.5 - 0.7 cm. The total length of the ureter in adults is 25 - 35 cm, located behind the peritoneum, and vertically descends along the front of the inner side of the psoas major muscle and then enters the pelvis.

[0003] The ureter has three narrow parts: one at the transition between the renal pelvis and the ureter (the starting point of the ureter), one at the crossing of the pelvic inlet, and the last one inside the bladder wall. These narrow parts are the areas where stones, blood clots, and necrotic tissues are likely to stay. In females, the ureter crosses the lateral side of the cervix uteri and then reaches the bladder. There is a special structure at the ureter - bladder junction, namely the Waldeyer sheath, which can effectively prevent the urine in the bladder from flowing back into the ureter.

[0004] Regarding the existing technology, there are the following problems:

Specific embodiments

[0023] The following further describes the present utility model in detail with reference to embodiments:

[0024] As Figures 1-5 shown, the present utility model provides a detachable disposable ureteropyeloscope, including a connecting pipe 1. A connecting wire 2 is inserted into the right end inside the connecting pipe 1, a flexible pipe 3 is inserted into the left end inside the connecting pipe 1. Disassembly and assembly mechanisms 4 are symmetrically installed on both sides of the connecting pipe 1. Socket seats 5 are symmetrically installed on both outer walls of the flexible pipe 3, and an insertion slot 6 is opened inside the socket seat 5.

[0025] The right end of the flexible pipe 3 is snap-fitted inside the left end of the connecting wire 2.

[0026] The bottom end of the socket seat 5 is symmetrically and fixedly connected to both outer walls of the flexible pipe 3. The insertion slot 6 inside the socket seat 5 is fitted with and movably installed with the insertion block 49.

[0027] Through the disassembly and assembly mechanism 4, under the elastic action of the spring 46, the movable plate 45 and the insertion block 49 can be pushed to move towards the flexible pipe 3, so that the insertion block 49 can be inserted into the insertion slot 6 inside the socket seat 5, thereby fixing the flexible pipe 3 inside the connecting pipe 1, making its installation convenient and fast; at the same time, the pull rod 43 and the pull handle 44 can be pulled outwards, so that the movable plate 45 and the insertion block 49 move synchronously, and then the insertion block 49 is separated from the insertion slot 6, and then it is convenient to disassemble the flexible pipe 3 from the connecting pipe 1, saving time and effort and improving the use effect of the device.

[0028] As Figures 3-5 shown, the disassembly and assembly mechanism 4 includes a groove 41 opened on both sides of the connecting pipe 1. A mounting frame 42 is sleeved outside the groove 41. A pull rod 43 is slidably penetrated through the top inside the cavity of the mounting frame 42. A pull handle 44 is fixedly installed at the top of the pull rod 43. A movable plate 45 is fixedly installed at the bottom of the pull rod 43. A spring 46 is sleeved outside the bottom of the pull rod 43. Limit blocks 47 are symmetrically and fixedly installed on both the front and rear sides of the movable plate 45. Limit slots 48 are opened on both the front and rear inner walls of the mounting frame 42 and the groove 41. An insertion block 49 is fixedly installed at the lower end of the movable plate 45.

[0029] The bottom end of the mounting frame 42 is fixedly connected to both outer walls of the connecting pipe 1, and the mounting frame 42 is communicated with the inside of the connecting pipe 1 through the groove 41.

[0030] The exterior of the movable plate 45 is movably connected to the interior of the mounting frame 42 and the groove 41.

[0031] One end of the spring 46 is fixedly connected to the upper side of the movable plate 45, and the other end is fixedly connected to the top inner wall of the mounting frame 42.

[0032] The limiting block 47 matches the limiting groove 48 and is slidably connected.

[0033] When the movable plate 45 moves in the groove 41 and the mounting frame 42, it will drive the limiting block 47 to slide synchronously in the limiting groove 48, thereby limiting the movable plate 45 and improving the stability when it moves up and down.

[0034] Next, specifically describe the working principle of the detachable disposable ureteropyeloscope.

[0035] As Figures 1-5 shown, when the detachable disposable ureteropyeloscope is in use, first pull the pull handle 44 outwards, so that the pull handle 44 drives the pull rod 43 to move synchronously, so that the pull rod 43 drives the plug block 49 to move synchronously through the movable plate 45, and at the same time squeezes the spring 46. Then, the hose 3 can be inserted into the connecting pipe 1, and the top end of the hose 3 is engaged into the bottom end inside the connecting wire 2. Then, the pull handle 44 can be released. Then, under the elastic return of the spring 46, the movable plate 45 and the pull rod 43 can be pushed downwards, so that the movable plate 45 drives the plug block 49 to move synchronously, so that the plug block 49 moves into the connecting pipe 1 and is positioned and inserted into the insertion slot 6 inside the socket 5, thereby limiting the socket 5, and then the hose 3 can be fixed in the connecting pipe 1, thereby improving the installation effect of the hose 3. When the pull handle 44 is pulled outwards, the pull rod 43 can drive the movable plate 45 and the plug block 49 to move outwards synchronously, so that the plug block 49 is separated from the insertion slot 6 inside the socket 5, so that the hose 3 can be disassembled, which is convenient for replacing it, improving the use effect of the device and achieving the function of saving time and effort.

[0036] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
