It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0031] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0032] See also Figures 1 to 4 The utility model provides a bladder lithotripsy, which comprises a mirror tube 1 and also includes:

[0033] The auxiliary tube 2 is integrally connected to the outer wall of the mirror tube 1, and one end of the auxiliary tube 2 is integrally connected to a terminal shell 3, and a first pull rope 4 and a second pull rope 5 are passed through the interior of the auxiliary tube 2;

[0034] The elastic telescopic component 7 is fixed inside the end shell 3 and is also tied to the first pull rope 4;

[0035] The clamping assembly 6 is fixed to the elastic telescopic assembly 7 and is tied to the second pull rope 5;

[0036] The elastic telescopic component 7 can drive the clamping component 6 to completely enter the interior of the terminal shell 3 .

[0037] It should be noted that: in this device, an integrated auxiliary tube 2 is also arranged outside the mirror tube 1, and a first pull rope 4 and a second pull rope 5 are inserted inside the auxiliary tube 2. At the same time, a terminal shell 3 is also arranged at one end of the mirror tube 1, and a clamping assembly 6 is installed inside the terminal shell 3 through an elastic telescopic assembly 7. The clamping assembly 6 can be used to clamp the stone, thereby ensuring the stability of the stone to facilitate subsequent crushing, and the elastic telescopic assembly 7 can be used to drive the clamping assembly 6 to move, so that the clamping assembly 6 can be completely inside or outside the terminal shell 3. When it is inside the terminal shell 3, the entire clamping assembly 6 is in a receiving state. Therefore, during the movement of the device inside the human body, no strong discomfort will be generated, and the comfort level during use is higher. When it is outside the human body, the clamping assembly 6 can be used normally to clamp and fix the stone.

[0038] It should also be noted that the other ends of the first pull cord 4 and the second pull cord 5 can be connected to the handle structure, so it will be more convenient to adjust and use.

[0039] In the embodiments of the present invention, please refer to Figure 2 and Figure 4 The elastic telescopic component 7 includes two mutually parallel positioning light rods 71, and a positioning plate 72 is slidably connected to the positioning light rods 71. One of the positioning light rods 71 ​​is also provided with a spring 73 that presses against the positioning plate 72;

[0040] Among them, the two positioning light rods 71 ​​are vertically welded to the bottom of the end shell 3, and the other end of the spring 73 is pressed against the bottom of the end shell 3;

[0041] One end of the first pull rope 4 is tied to the positioning plate 72;

[0042] The length of the positioning polished rod 71 is greater than the length of the end shell 3 .

[0043] It should be noted that: in the elastic telescopic assembly 7, the positioning plate 72 slides on the positioning light rod 71, and the first pull rope 4 is tied to the positioning plate 72. Pulling the first pull rope 4 can drive the positioning plate 72 to move toward the inside of the end shell 3, and the spring 73 is compressed at this time;

[0044] The length of the positioning light rod 71 is greater than the length of the terminal shell 3 , so the positioning plate 72 can be completely moved to the outside of the terminal shell 3 .

[0045] In the embodiments of the present invention, please refer to Figures 1 to 3 , the clamping assembly 6 includes a fixing plate 61, and a first clamping plate 62 is fixed to one end of the fixing plate 61;

[0046] The fixed plate 61 is rotatably connected to a movable plate 64 via a rotating shaft 63. A torsion spring 65 is sleeved on the rotating shaft 63 to press against the movable plate 64. A second clamping plate 66 is fixed to one end of the movable plate 64, and a connecting ring 67 is passed through the other end.

[0047] One end of the fixing plate 61 is welded to one side of the positioning plate 72, and a through hole 8 is formed on the positioning plate 72, and the second pull rope 5 passes through the through hole 8 and is tied to the connecting ring 67;

[0048] The elastic force of the torsion spring 65 is smaller than the elastic force of the spring 73 .

[0049] It should be noted that: in the clamping assembly 6, the movable plate 64 can rotate, and one end of the movable plate 64 is tied to the second pull rope 5 through the connecting ring 67, so that the second pull rope 5 can generate a force on the movable plate 64, so that the movable plate 64 rotates, and then the second clamping plate 66 and the first clamping plate 62 clamp the stone;

[0050] The fixing plate 61 is fixed on the positioning plate 72, so when the positioning plate 72 moves to the inside of the end head shell 3, the entire clamping assembly 6 will also move together to achieve the storage of the clamping assembly 6;

[0051] It should also be noted that the elastic force of the torsion spring 65 is smaller than the elastic force of the spring 73 , so when the movable plate 64 is clamped by the second pull rope 5 , the entire clamping assembly 6 will not move.

[0052] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
