Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an adjustable anti-blocking suction device. Background Art

[0002] Laparoscopic surgery is a newly developed minimally invasive procedure and an inevitable trend in the future of surgical treatment. With the rapid advancement of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. Coupled with the increasing proficiency of surgeons, many previously open surgeries have been replaced by endoscopic procedures, greatly expanding surgical options. The advantages of single-port laparoscopic surgery are significant. First, it is minimally invasive, requiring only a single, small incision and resulting in minimal scarring, a feature particularly noteworthy for young people and women who value beauty. Second, the straightforward approach minimizes damage to surrounding tissues and reduces the risk of postoperative adhesions. Third, postoperative wound pain is significantly reduced. Fourth, hospital stays are shortened, with some patients being discharged in just 2-3 days and fully recovered and returning to work in 7 days. This significantly reduces patient costs and accelerates hospital bed turnover. Aspirators are essential to maintain the surgical field of view during surgery.

[0003] During the aspiration process, existing aspirators are prone to blockage when tissue fragments, especially blood clots, enter the tube body, affecting the aspiration effect and the health of the patient. At the same time, most existing aspirators have a single aspirator structure, which lacks the power to flow the liquid and cannot guarantee a good aspiration effect over a long distance. They are inflexible to use and have great limitations. Summary of the Invention

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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.

[0049] Please also refer to Figures 1 to 6 A specific embodiment of an adjustable anti-blocking suction device provided by the present invention is now described.

[0050] For ease of explanation, see Figure 1 , establish a rectangular coordinate system with any point in space as the origin, the setting direction of the probe 1 as the Z axis, the setting direction of the first attraction component 2 as the Y axis, and the straight line direction perpendicular to the Y axis and the Z axis as the X axis, where the XY plane is the horizontal plane, the direction indicated on the horizontal plane is the horizontal direction, and the direction indicated by the Z axis is the vertical direction.

[0051] In this embodiment, the unblocking assembly 5 includes a water pipe and a water tank. The water tank is connected to the shifting assembly 3 via the water pipe. Water is fed into the shifting assembly 3. The water interacts with tissue fragments, particularly blood clots, and disperses them, thereby unblocking the blockage. The water tank stores clean water or a decomposing agent for dilution. This provides anticoagulation during use and efficient cleaning after use.

[0052] Compared with the existing technology, this adjustable anti-blocking suction device provides driving force for the movement of the liquid at the front and end of the suction through the cooperation of the first suction component 2 and the second suction component 4, which not only ensures that there is sufficiently strong suction at the front, but also ensures that there will be no jamming in the process of transferring the liquid out at the back end. It can be used for both long and short distances and has fewer limitations on use; the first suction component 2 can be used as a suction driving device for body fluids at the lesion, and can also be used as a suction driving device for the liquid in the dredging component 5. It has a simpler structure and better use effect; through the setting of the dredging component 5, the blood clot can be efficiently diluted, thereby achieving the effect of dredging, and the effect is significant.

[0053] As another embodiment of the present invention, the structure of this adjustable anti-blocking suction device is basically the same as the structure in the above embodiment, the difference being that the first suction component 2 includes a first suction device 21, a one-way control component 22, and a power supply component 23, wherein the first suction device 21 is connected to the probe 1 and the gear adjustment component 3 at the same time, and is used to provide power for the movement of the liquid; the one-way control component 22 is arranged between the probe 1 and the first suction device 21, and the one-way control component 22 can be a one-way valve, which is used to prevent the liquid from flowing back to the probe 1; the power supply component 23 is detachably connected to the first suction device 21, and the power supply component 23 is a detachable rechargeable battery pack, which is used to power the first suction device 21.

[0054] As another embodiment of the present invention, the structure of the adjustable anti-blocking suction device is basically the same as that in the above embodiment, the difference is that the gear shifting component 3 includes a support member 31, a gear shifting member 32, and a gear shifting handle 33, wherein one end of the support member 31 is provided with a accommodating chamber 311 communicating with the first suction component 2, and the other end is provided with a first liquid guide chamber 312 communicating with the dredging component 5 and a second liquid guide chamber 313 communicating with the second suction component 4, and the support member 31 is further provided with a mounting position 314, which is arranged between the accommodating chamber 311 and the first liquid guide chamber 312 and the second liquid guide chamber 313, and can be a cylindrical cavity, and the mounting position 314 is provided with a A plurality of through holes are respectively connected to the accommodating chamber 311, the first liquid guiding chamber 312 and the second liquid guiding chamber 313; the shifting member 32 is connected to the support member 31 and is arranged on the installation position 314. The shifting member 32 is rotatably connected to the support member 31. The shifting member 32 is provided with a first liquid guiding hole 321 and a second liquid guiding hole 322 connected to the first liquid guiding hole 321. The shifting member 32 is connected to a plurality of through holes at the same time. The shifting member 32 is used to connect the accommodating chamber 311 with the first liquid guiding chamber 312 or the second liquid guiding chamber 313; the shifting handle 33 is fixedly connected to the shifting member 32 and is rotatably connected to the support member 31. The shifting handle 33 is arranged through the support member 31 to drive the shifting member 32 to rotate.

[0055] In this embodiment, the shifting member 32 also includes a third liquid-conducting cavity 323 that is connected to both the first liquid-conducting hole 321 and the second liquid-conducting hole 322. During use, the first liquid-conducting hole 321 is adjusted to connect with the second liquid-conducting cavity 313, and the second liquid-conducting hole 322 is adjusted to connect with the receiving cavity 311. This allows the liquid at the lesion to be aspirated. If a blockage occurs, the shifting handle 33 is rotated to connect the first liquid-conducting hole 321 with the receiving cavity 311, and the second liquid-conducting hole 322 with the first liquid-conducting cavity 312. This allows water to flush the third liquid-conducting cavity 323 and the receiving cavity 311, diluting the liquid and resolving the blockage. This multi-stage adjustment method, which changes the flushing and aspiration state, promptly resolves blockages and prevents them from impacting the procedure.

[0056] As another embodiment of the present invention, the structure of this adjustable anti-blocking suction device is basically the same as that of the above-mentioned embodiment, except that the second suction assembly 4 includes an input pipe 41, a storage box 42, a drainage member 43, and an output pipe 44. The input pipe 41 is connected to the shift assembly 3 via a connecting pipe 45; the storage box 42 is connected to the input pipe 41 and is provided with a liquid storage chamber 421 for holding liquid; the drainage member 43 is connected to both the input pipe 41 and the storage box 42 to drain a blocked input pipe 41; and the output pipe 44 is connected to the storage box 42 and extends into the liquid in the liquid storage chamber 421. A second aspirator 46 is connected to the output pipe 44 to provide a driving force for liquid movement.

[0057] In this embodiment, a U-shaped interface is provided between the input tube 41 and the connecting tube 45. The U-shaped interface is an L-shaped tubular structure with an angle of 90°, which is used to prevent blockage. More specifically, the connecting tube 45 is a hose. When it is directly connected to the input tube 41, the hose may be folded due to its softness, causing blood clots, tissues, etc. to block the tube opening. The U-shaped interface is designed on the input tube 41 as a transition structure for the connection. On the one hand, it prevents the connecting tube 45 from being folded. On the other hand, the U-shaped interface (a rubber ring or other material that can increase the sealing performance) can be used to increase the sealing performance of the input tube 41, thereby increasing the attraction force of the second suction component 4.

[0058] As another embodiment of the present invention, the structure of this adjustable anti-blocking suction device is basically the same as that of the above-mentioned embodiment, except that the dredging member 43 includes a button 431, an elastic member 432, a connecting post 433, and a squeezing ring 434. The button 431 is slidably connected to the receiving box 42 and is disposed through the receiving box 42. The elastic member 432 is disposed between the button 431 and the receiving box 42 and may be a spring for providing a rebound force for the button 431. The connecting post 433 is connected to the button 431 and is disposed within the liquid storage chamber 421. The squeezing ring 434 is fixedly connected to the connecting post 433 and slidably connected to the input tube 41. The input tube 41 is disposed through the squeezing ring 434 and moves axially along the input tube 41 to dredge a clogged input tube 41. Pressing the button 431 causes the squeezing ring 434 to move up and down, squeezing the input tube 41 and reducing or squeezing the blood clot or other obstructing structure out of the input tube 41, thereby achieving the purpose of dredging. The pressing and unclogging method has a simpler structure and is more convenient to operate.

[0059] As another embodiment of the present invention, the structure of this adjustable anti-blocking suction device is basically the same as that of the above-mentioned embodiment, except that the input tube 41 includes a tube body 411, a squeezing platform 412, and a support frame 413. One end of the tube body 411 is connected to the connecting tube 45, and the other end passes through the storage box 42 and extends into the liquid storage chamber 421. The tube body 411 passes through the squeezing ring 434. The squeezing platform 412 is integrally formed with the tube body 411 and is disposed on the side of the squeezing ring 434 away from the button 431. The squeezing platform 412 is provided with an inclined surface 4121, along which the squeezing ring 434 slides to squeeze the squeezing platform 412. The support frame 413 is connected to both the storage box 42 and the tube body 411 and is used to limit the position of the tube body 411. Any device that can achieve the above-mentioned performance and functions of the input tube 41 is within the scope of protection of this application.

[0060] In this embodiment, a slide groove 422 is provided on the receiving box 42, and a slider adapted to the slide groove 422 is provided on the button 431. One end of the elastic member 432 is connected to the end of the slide groove 422 away from the slider, and the other end is connected to the slider; a sealing plug 47 is provided between the connecting column 433 and the receiving box 42 to prevent liquid from overflowing.

[0061] As another embodiment of the present invention, the structure of this adjustable anti-blocking suction device is basically the same as the structure in the above embodiment, the difference being that a liquid guide column 315 is provided in the accommodating cavity 311, and the liquid guide column 315 has a triangular cross-section and is used to guide the flow direction of the liquid absorbed by the probe 1 or the dredging liquid input by the dredging component 5.

[0062] Please also refer to Figures 1 to 7 As another embodiment of the present invention, the structure of this adjustable anti-blockage suction device is essentially the same as that of the aforementioned embodiment. The difference lies in that the diameter of the end of the input tube 41 where it connects to the connecting tube 45 is smaller than the diameter of the other end, and the diameter of the bottom of the input tube 41 is larger, which allows for better liquid transport and prevents blockage. Simultaneously, the squeezing ring 434 can more fully squeeze the input tube 41, improving the unblocking effect when a blockage occurs. A second suction device 46 is connected to the input tube 41 to provide a driving force for liquid movement. Both the first suction device 21 and the second suction device 46 can be electric suction devices.
