Detailed implementation mode

[0015] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation modes.

[0016] As Figures 1-8 shown, a lithotripter for digestive department of the present invention includes a grip rod 1 and a probe 2. A connecting pipe 3 is fixedly connected to the grip rod 1. A micro air pump 4 is fixedly installed on one side of the grip rod 1. A connecting groove 5 is opened on one side of the probe 2. A connecting ring 6 is fixedly connected to the connecting pipe 3. A plurality of sliding grooves 7 arranged in an array are opened on the connecting ring 6. A clamping groove 8 is opened at a position adjacent to the sliding groove 7 on the connecting ring 6; An annular groove 9 is opened on the probe 2. A plurality of guide rods 10 arranged in an array are fixedly connected to the inner wall of the annular groove 9. Springs 11 are fixedly connected to the inner wall of the annular groove 9 corresponding to the positions of the guide rods 10. A moving ring 12 is slidably connected inside the annular groove 9. A plurality of extrusion rods 13 arranged in an array are fixedly connected to one side of the moving ring 12; A mounting ring 14 is slidably connected inside the probe 2. A rubber layer 15 is fixedly connected to one side of the mounting ring 14. A collection bag 16 is fixedly connected to the outer wall of the rubber layer 15. A blocking ring 17 is fixedly connected to the inner part of the probe 2 corresponding to the position of the rubber layer 15. A plurality of mounting grooves 18 arranged in an array are opened on the probe 2. Round rods 19 are rotatably connected inside the mounting grooves 18. Blocking rods 20 are fixedly connected to the round rods 19. Torsion springs 21 are fixedly connected to the inner parts of the mounting grooves 18 corresponding to the positions of the round rods 19. A plurality of clamping rods 22 arranged in an array are fixedly connected to one side of the probe 2 corresponding to the position of the connecting ring 6. Pressure receiving grooves 23 are opened on the blocking rods 20.

[0017] One side of the connecting pipe 3 is movably connected to the inside of the connecting groove 5. The connecting pipe 3 is communicated with the probe 2. A filter screen 24 is fixedly connected to the inside of the connecting groove 5. The sliding grooves 7 and the clamping grooves 8 are in a communicating state. The specific shape of the clamping rods 22 is set to be L-shaped. One ends of the clamping rods 22 are all slidably connected to the inside of the clamping grooves 8. The communication between the sliding grooves 7 and the clamping grooves 8 facilitates the clamping rods 22 to be connected to the inside of the clamping grooves 8 through the sliding grooves 7. One ends of the springs 11 are all fixedly connected to the side walls of the moving rings 12. One ends of the guiding rods 10 are all slidably connected to the moving rings 12. The specific shape of the pressing rods 13 is set to be L-shaped. One ends of the pressing rods 13 all slidably penetrate through the probe 2 and are located inside the installation groove 18 and the pressure receiving groove 23. The springs 11 can jointly ensure the position stability of the moving rings 12 and also facilitate driving the moving rings 12 to complete the reset action. The pressing rods 13 facilitate pressing the pressure receiving groove 23, and the guiding rods 10 facilitate guiding the movement of the moving rings 12. The specific shape of the rubber layer 15 is conical. The diameter of one side of the rubber layer 15 is larger than that of the other side. The rubber layer 15 and the collection bag 16 are both located inside the probe 2. The outer wall of the rubber layer 15 abuts against the blocking ring 17. One side of the mounting ring 14 abuts against the blocking rod 20. The blocking rod 20 and the blocking ring 17 can jointly limit the mounting ring 14 and the rubber layer 15. One ends of the torsion springs 21 are all fixedly connected to the blocking rods 20. The specific shape of the blocking rods 20 is set to be L-shaped. One end of the connecting pipe 3 is fixedly connected to the output port of the micro air pump 4. The torsion springs 21 facilitate driving the blocking rods 20 to perform the reset action.

[0018] In use, the connecting pipe 3 and the probe 2 can be inserted into the patient's body through the detected gastric tube. The probe 2 can be aligned with the corresponding calculus, and then the micro air pump 4 is started. The micro air pump 4 will generate suction through the connecting pipe 3 to suck the calculus into the interior of the collection bag 16 through the rubber layer 15. The diameter of the corresponding position of the rubber layer 15 and the collection bag 16 is smaller than that of the other side. Therefore, the calculus placed inside the collection bag 16 cannot move out from the inside of the collection bag 16. By repeating the above operation steps repeatedly, the calculus can be taken out, avoiding the need for the staff to repeatedly take out the calculus, reducing the time required for the patient's treatment, and improving the treatment efficiency. When the collection bag 16 needs to be taken out from the inside of the probe 2, the moving ring 12 can be moved. The movement of the moving ring 12 in the annular groove 9 will drive the plurality of extrusion rods 13 to move together, and the guide rod 10 guides the movement of the moving ring 12. At the same time, the movement of the moving ring 12 will also squeeze and contract the plurality of springs 11. The protruding positions of the extrusion rods 13 will all slide in the installation groove 18, and the protruding parts of the extrusion rods 13 will all squeeze the pressure receiving grooves 23. When the pressure receiving grooves 23 are squeezed, they will act on the blocking rods 20. At this time, the blocking rods 20 will drive the round rods 19 to rotate together. At this time, the plurality of blocking rods 20 will all rotate outward from the installation groove 18, and when the blocking rods 20 rotate, they will all tighten the torsion springs 21. The rotation of the plurality of blocking rods 20 will no longer abut against the installation ring 14. At this time, the staff can take out the installation ring 14, the rubber layer 15 and the collection bag 16 from the inside of the probe 2, and then centrally dispose of the calculus inside the collection bag 16. When the probe 2 needs to be disassembled, the probe 2 can be directly rotated. The rotation of the probe 2 will drive the clamping rods 22 to rotate. At this time, each clamping rod 22 will rotate inside the clamping groove 8. When the probe 2 drives the clamping rods 22 to rotate to the corresponding sliding groove 7 position inside the clamping groove 8, the probe 2 can be directly moved in the direction away from the connecting pipe 3. At this time, the connecting groove 5 on the probe 2 will be separated from one end of the connecting pipe 3, and the clamping rods 22 will move from inside the clamping groove 8 to inside the sliding groove 7 and then be completely separated from the sliding groove 7, which is convenient for separately disinfecting the probe 2, the installation ring 14, the rubber layer 15 and the collection bag 16.
