At the same time, the negative pressure suction system is started, and the crushed stone particles together with the irrigation fluid are sucked out of the body with the help of the pressure difference in the pipeline, realizing the simultaneous crushing and removal.
[0004] In existing urinary stone lithotripsy surgeries, due to the single function of traditional instruments, the laser lithotripsy component and the negative pressure suction device are designed independently, which requires the doctor to hold the laser fiber for lithotripsy with one hand and operate a separate negative pressure suction stone removal device with the other hand. This separate operation requires both hands to hold the instruments, which occupy more endoscopic working channels, limits the use space of other auxiliary instruments during the operation, increases the difficulty of operational coordination, and thus reduces the efficiency of lithotripsy removal, affecting the surgical effect.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments 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.
[0030] Please see the attached Figure 1 -Attached Figure 4The embodiment of the present invention provides a urological stone crushing and aspiration device, including a main box 1 and a crushing box 2. A collecting box 11 is installed on the main box 1, an air pump 19 is installed inside the collecting box 11, and a delivery pipe 20 is fixedly connected to the input end of the air pump 19. A crushing component 9 is provided inside the crushing box 2. A circular tube 1 3 is fixedly connected to the top of the crushing box 2, and a circular tube 2 4 is slidably connected to the circular tube 1 3 at one end of the circular tube 1 3 away from the crushing box 2. An adjusting component 7 is provided between the circular tube 1 3 and the circular tube 2 4. An end of the circular tube 2 4 away from the circular tube 1 3 is fixedly connected to the annular tube 2 12, and an end of the annular tube 12 away from the circular tube 2 4 is installed with a circular tube 3 5. An end of the circular tube 3 5 away from the annular tube 2 12 is fixedly connected to a connecting tube 6, and an end of the connecting tube 6 away from the circular tube 3 5 is fixedly connected to the annular tube 1 15. A laser is installed in the middle of the annular tube 15. An adsorption port 13 is provided between the optical fiber 14, the laser optical fiber 14 and the annular tube 15, and adsorption holes 16 are evenly provided inside the annular tube 15. A disassembly and assembly component 8 is provided between the annular tube 2 12 and the circular tube 3 5. A handle 17 is fixedly connected to the circular tube 3, and a control button 18 is installed on the handle 17. A support column 10 is installed between the main box 1 and the crushing box 2. The collection box 11 is fixedly connected to the top of the support column 10, and the delivery pipe 20 is fixedly connected to the inside of the crushing box 2. The adsorption port 13 and the adsorption holes 16 are connected to the collection box 11 in sequence through the connecting pipe 6, circular tube 3 5, annular tube 2 12, circular tube 2 4, circular tube 1 3, crushing box 2, delivery pipe 20 and air pump 19. The interiors of the annular tube 15 and the annular tube 2 12 are specifically configured to be ring-shaped and adapted to the interiors of the circular tube 1 3, circular tube 2 4 and circular tube 3 5.
[0031] Specifically, after the medical staff presses the control button 18 to activate the device, the laser fiber 14 outputs a pulsed laser of a specific energy, which directly acts on the surface of the stone, causing the stone to break into fragments of different sizes under the impact of the laser energy. During this process, the annular channels opened inside the annular tube 15 and the annular tube 2 12 play a diversion role. The air pump 19 is synchronously started and generates a continuous negative pressure. This negative pressure is sequentially transmitted to the interior of the crushing box 2 through the delivery tube 20, and then transmitted to the annular tube 1 15 through the annular channel through the circular tube 1 3, the circular tube 2 4, the circular tube 3 5, and the connecting tube 6. A directional suction field is formed at the suction port 13 and the multiple suction holes 16. The multiple suction points work together to more comprehensively cover the stone crushing area and promptly suck in the surrounding stone fragments. This method eliminates the need for medical staff to operate the laser fiber 14 with one hand and the suction device with the other hand, reducing the number of operating instruments, reducing the difficulty of operation to a certain extent, and helping to improve the coordination of operations during the operation.
[0032] Please see the attached Figure 5The adjustment component 7 includes a bolt 71, which is installed between the circular tube 1 3 and the circular tube 2 4. The interior of the circular tube 2 4 is evenly provided with bolt holes 2 74, and the interior of the circular tube 1 3 is provided with bolt hole 1 73. The bolt 71 is threadedly connected to the interior of the bolt hole 1 73 and the bolt hole 2 74. The end of the bolt 71 away from the circular tube 1 3 is fixedly connected to the knob 72.
[0033] Specifically, the medical staff loosens the bolt 71 to disengage the bolt 71 from the bolt hole 1 73 and the currently corresponding bolt hole 2 74, and then pushes or pulls the round tube 2 4 to change its overlapping length with the round tube 1 3. After adjusting to the appropriate length, the bolt hole 1 73 on the round tube 1 3 is aligned with the bolt hole 2 74 at the corresponding position on the round tube 2 4, and then tightens the bolt 71 to allow it to pass through the bolt hole 1 73 and screw into the bolt hole 2 74, thereby fixing the relative positions of the round tube 1 3 and the round tube 2 4, and completing the adjustment of the length of the device inserted into the body. This adjustment method is relatively simple to operate, and can enable the device to adapt to different surgical sites and patient conditions, thereby improving the applicability of the device in surgery to a certain extent.
[0034] Please see the attached Figure 6 The disassembly assembly 8 includes a thread 81, which is provided on the surface of the round tube 3 5. A bolt hole 82 is provided inside the annular tube 12, and the round tube 3 5 is threadedly connected to the inside of the bolt hole 82.
[0035] Specifically, the medical staff rotates the round tube three 5 so that the thread 81 on the surface of the round tube three 5 is gradually disengaged from the bolt hole three 82 inside the annular tube two 12, thereby removing the round tube three 5 from the annular tube two 12. At this time, the end structure adapted to different parts can be replaced. After the replacement is completed, the new round tube three 5 is aligned with the bolt hole three 82 of the annular tube two 12, and the round tube three 5 is rotated in the opposite direction so that the thread 81 on the surface of the round tube three 5 and the bolt hole three 82 inside the annular tube two 12 are engaged with each other until tightened to achieve reconnection. This method can flexibly select the appropriate end structure according to different surgical sites and stone conditions, which helps to meet diverse surgical operation needs.
[0036] Please see the attached Figure 7 The crushing assembly 9 includes a micro motor 91, which is installed at the end of the crushing box 2 away from the circular tube 3. The output end of the micro motor 91 is fixedly connected to a rotating shaft 92, and a blade 93 is evenly fixedly installed on the surface of the rotating shaft 92. The rotating shaft 92 and the blade 93 are both rotatably connected to the inside of the crushing box 2.
[0037] Specifically, the micro motor 91 is started to drive the rotating shaft 92 to rotate at high speed, and the rotating shaft 92 drives the blade 93 on the surface to rotate synchronously. When larger gravel fragments flow through the crushing box 2, the rotating blade 93 will repeatedly cut and grind them, and the larger fragments will be refined into fine particles that are easier to pass through the passage. The cut and ground fragments continue to move along the passage formed by the circular tube 1 3, the circular tube 2 4, etc., and are finally collected completely into the collection box 11. This process can reduce the possibility of larger fragments being blocked in the passage, make the fragment transportation smoother, and help improve the efficiency of gravel collection.
[0038] Working principle: When in use, medical staff press the control button 18 to trigger the device to start. The laser fiber 14 then outputs a pulsed laser of a specific energy, which directly acts on the surface of the stone, causing the stone to break into fragments of different sizes under the impact of the laser energy. At the same time, the air pump 19 starts and generates a continuous negative pressure. This negative pressure is transmitted to the inside of the crushing box 2 through the delivery pipe 20 in sequence, and then transmitted to the annular pipe 1 15 through the circular pipe 1 3, the circular pipe 2 4, the circular pipe 3 5, and the connecting pipe 6. A directional suction field is formed at the suction port 13 and the suction hole 16, which sucks in the surrounding stone fragments.
[0039] After the debris enters the passage, the larger pieces will flow through the crushing assembly 9 in the crushing box 2. At this time, the micro motor 91 drives the rotating shaft 92 to rotate at high speed, driving the blade 93 to cut and grind the larger pieces, making them finer and easier to transport. The processed pieces continue to move along the passage and are finally collected in the collection box 11.
[0040] When the length of the device inserted into the body needs to be adjusted during surgery, the bolt 71 is loosened, and the second tube 4 is pushed or pulled to change the overlapping length with the first tube 3. The bolt hole 1 73 and the second bolt hole 74 at the corresponding position are aligned and then the bolt 71 is tightened to fix the device. The length adjustment is completed.
[0041] If the end structure needs to be replaced to adapt to different parts, the circular tube 3 5 is rotated to disengage the thread 81 on its surface from the bolt hole 3 82 in the annular tube 2 12 . After replacement, reverse rotation is performed to achieve reconnection, thereby meeting the needs of diverse surgical operations.
[0042] While embodiments of the present invention have been shown and described, it will be appreciated 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 invention, and that the scope of the invention is defined by the appended claims and their equivalents.
