Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an intraoperative targeted and precise suction device for effusion and its usage method. Background Technology

[0002] Intraoperative aspiration is a medical device used to actively remove fluid from the surgical area during surgery. It typically consists of a negative pressure unit, connecting tubing, and a suction head adapted to different surgical scenarios. It uses negative pressure suction to quickly remove blood, tissue fluid, irrigation fluid, and other fluids from the surgical site. This not only maintains a clear surgical field to ensure precise operation by the surgeon and avoid accidental injury, but also reduces residual fluid to lower the risk of postoperative infection. At the same time, it maintains a dry environment in the surgical area, facilitating the use of instruments and tissue processing.

[0003] Existing aspiration devices for fluid drainage usually require constant manual monitoring of the fluid volume and manual drainage during surgery. This forces medical staff to be distracted by handling the fluid container during the operation, disrupting the surgical rhythm and hindering the normal and stable progress of the surgery. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an intraoperative targeted and precise aspirator for effusion and its usage method, solving the problem that existing effusion aspirators typically require manual observation of the effusion volume and manual drainage during drainage, which is not conducive to the normal and stable progress of the surgery.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intraoperative targeted precision aspirator for effusion, comprising an aspiration tube, a valve fixedly connected to the outer wall of the aspiration tube, a specimen bottle disposed on the lower surface of the valve, an aspirator container fixedly connected to the end of the valve away from the aspiration tube, multiple outlet tubes fixedly connected to the inner bottom wall of the aspirator container, a partition fixedly connected inside the aspirator container, the partition dividing the interior of the aspirator container into an upper and lower empty chamber, a sliding plate slidably connected inside the aspirator container, an electric push rod fixedly disposed on the lower surface of the aspirator container, the drive end of the electric push rod fixedly connected to the lower surface of the sliding plate, multiple adjustment components disposed inside the electric push rod, each adjustment component including a connecting block, a connecting rod fixedly connected inside the connecting block, multiple sealing plugs fixedly connected to the outer wall of the connecting rod, and the outer wall of the sealing plugs slidably connected to the interior of the outlet tubes.

[0009] Preferably, a plurality of magnetic blocks are fixedly connected to the outer wall of the connecting plate, and magnetic blocks are magnetically attracted to the side of the magnetic blocks away from the connecting plate. The outer wall of the magnetic blocks is fixedly connected to the inside of the suction barrel.

[0010] Preferably, the upper surface of the sliding plate is attached to the base plate, and the upper surface of the base plate is fixedly provided with a plurality of transmission components, the transmission components including a slide rod, the top end of the slide rod being fixedly connected to the lower surface of the partition.

[0011] Preferably, the transmission assembly further includes a housing, the lower surface of which is fixedly connected to the upper surface of the base plate. A fixing frame is fixedly installed inside the housing, and the lower surface of the fixing frame is fixedly connected to the upper surface of the base plate. The outer wall of the slide rod is slidably connected to the housing and the fixing frame. A slider is slidably connected inside the fixing frame. The upper surface of the slider is fixedly connected to the bottom end of the slide rod. An elastic element two is fixedly connected to the lower surface of the slider. The end of the elastic element two away from the slider is fixedly connected to the inner bottom wall of the fixing frame. A rotating plate is slidably connected inside the slider. The end of the rotating plate away from the slider is rotatably connected to the inside of the fixing frame. A sliding groove is formed inside the slider, and the rotating plate is slidably connected to the sliding groove.

[0012] Preferably, an air guiding assembly is fixedly disposed inside the sliding plate. The air guiding assembly includes a fixed column, the outer wall of which is fixedly connected to the inside of the sliding plate. A sliding column is slidably connected inside the fixed column. The top end of the sliding column is attached to the lower surface of the partition. An elastic element is fixedly disposed on the outer wall of the sliding column. The elastic element is fixedly disposed inside the fixed column. An airbag is attached to the lower surface of the sliding column. The outer wall of the airbag is fixedly disposed inside the fixed column. An air guiding tube is fixedly disposed inside the airbag. The outer wall of the air guiding tube is fixedly disposed inside the fixed column. A sliding assembly is disposed at the end of the air guiding tube away from the fixed column. The sliding assembly is fixedly disposed inside the sliding plate.

[0013] Preferably, the sliding assembly includes a fixed post 2, the outer wall of which is fixedly disposed inside the sliding plate. Multiple sliding posts 2 are slidably connected inside the fixed post 2. An elastic element 4 is fixedly connected to one end of each sliding post 2, and a sealing plate is fixedly connected to the other end of each sliding post 2. The sealing plate is slidably connected inside the sliding plate. Multiple iron blocks are fixedly connected inside the sliding plate. The sealing plate is magnetically adsorbed onto the outer wall of the iron blocks. Multiple magnetic blocks 3 are fixedly connected to the inner bottom wall of the suction barrel. Multiple grooves are formed inside the sliding plate. The magnetic blocks 3 are slidably connected to the grooves. The sealing plate and the magnetic blocks 3 are magnetically repelled on opposite sides.

[0014] Preferably, the magnetic block three has a notch inside, and the size of the notch is adapted to the connecting rod.

[0015] Preferably, the method of using an intraoperative targeted precision aspirator for effusion includes the following steps: S1. Activate the electric push rod to move the sliding plate upward, further contacting the top head and causing it to rotate inside the suction tank, which in turn drives the connecting plate and connecting block to rotate. When the connecting block rotates, it will drive the connecting rod to move upward, which in turn drives the sealing plug to move upward. S2. When the sliding plate continues to slide upward, it will fit against the base plate, which will further drive the sliding rod to slide inside the outer shell and the fixed frame, thereby causing the slider to slide inside the fixed frame. At this time, the rotating plate will slide inside the slider through the slide groove, which will further drive the base plate to slide inside the partition. S3. When the sliding plate is in contact with the base plate, it will also cooperate with the partition to make the sliding column one slide inside the fixed column one and compress the air bag inside it. The gas generated by the compressed air bag is delivered to the fixed column two through the air guide pipe, which further pushes the sliding column two to drive the sealing plate to slide inside the sliding plate.

[0016] Working principle: The negative pressure is controlled by an external controller, and the accumulated liquid is drawn out through the suction tube. The valve is used to switch the flow direction of the accumulated liquid, so that it enters the specimen bottle or the suction container. When it is necessary to drain the accumulated liquid in the suction container, the electric push rod is activated to drive the sliding plate to move upward. The initial opening of the hole inside the sliding plate is used to allow the accumulated liquid above to flow to the bottom to maintain the negative pressure inside the suction container. When the sliding plate contacts the adjustment component, it will drive the connecting rod and the sealing plug to slide out from the liquid outlet tube through the connecting block, thereby achieving the effect of automatically draining the accumulated liquid in the empty compartment of the suction container without affecting the suction of the accumulated liquid.

[0017] This invention provides an intraoperative targeted and precise aspirator for effusion and its usage method. It offers the following advantages: 1. This invention uses a sliding plate to drive the top head to rotate, which in turn drives the connecting plate to rotate. When the connecting plate rotates, it drives the sealing plug to slide out from inside the liquid outlet pipe through the connecting block and connecting rod, thereby automatically draining the liquid accumulated inside the lower chamber. This avoids the waiting time that medical staff need to spend manually draining the liquid, ensuring that the surgery can be performed stably.

[0018] 2. This invention uses a sliding plate to drive the bottom plate to slide inside the partition, thereby automatically sealing the partition when draining the liquid in the lower chamber, preventing changes in the negative pressure inside the suction tank that would prevent the liquid from being properly absorbed.

[0019] 3. The present invention uses the second sliding column to drive the sealing plate to slide inside the sliding plate, thereby automatically sealing the holes opened inside the sliding plate when the liquid in the lower empty chamber is discharged, thus improving the discharge rate of the liquid.

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Please see the appendix Figure 1 - Appendix Figure 6 This invention provides an intraoperative targeted aspirator for effusion, comprising an aspiration tube 1, a valve 2 fixedly connected to the outer wall of the aspiration tube 1, a specimen bottle 3 disposed on the lower surface of the valve 2, an aspirator container 4 fixedly connected to the end of the valve 2 away from the aspiration tube 1, multiple outlet tubes 5 fixedly connected to the inner bottom wall of the aspirator container 4, a partition 6 fixedly connected inside the aspirator container 4, the partition 6 dividing the interior of the aspirator container 4 into an upper empty chamber 7 and a lower empty chamber 8, a sliding plate 9 slidably connected inside the aspirator container 4, an electric push rod 10 fixedly disposed on the lower surface of the aspirator container 4, the drive end of the electric push rod 10 fixedly connected to the lower surface of the sliding plate 9, multiple adjustment components 11 disposed inside the electric push rod 10, each adjustment component 11 including a connecting block 113, a connecting rod 12 fixedly connected inside the connecting block 113, multiple sealing plugs 13 fixedly connected to the outer wall of the connecting rod 12, and the outer wall of the sealing plugs 13 slidably connected inside the outlet tubes 5.

[0024] Specifically, the negative pressure is first controlled by an external controller and the accumulated liquid is drawn out through the suction tube 1. The valve 2 is used to change the flow direction of the accumulated liquid, that is, to flow into the specimen bottle 3 or the suction tank 4. When it is necessary to drain the accumulated liquid inside the suction tank 4, the electric push rod 10 is first turned on to drive the sliding plate 9 to move upward. The hole opened inside the sliding plate 9 is initially in the open state to ensure that the accumulated liquid above it can flow smoothly into the lower part of the sliding plate 9, so as to avoid affecting the negative pressure inside the suction tank 4. After the sliding plate 9 moves upward a certain distance, it will contact the adjustment component 11, and then drive the connecting rod 12 to move upward through the connecting block 113. When the connecting rod 12 moves upward, the sealing plug 13 will slide out from the inside of the liquid outlet tube 5 through the fixing action of the connecting rod 12 and the sealing plug 13, thereby achieving the effect of automatically draining the accumulated liquid inside the lower empty chamber 8.

[0025] Please see the appendix Figure 3 - Appendix Figure 6 The adjustment assembly 11 also includes a top head 111, with a connecting plate 112 fixedly connected to the outer wall of the top head 111. The outer wall of the connecting plate 112 is rotatably connected to the inside of the suction barrel 4. One end of the connecting plate 112 near the electric push rod 10 is rotatably connected to the outer wall of the connecting block 113. The outer wall of the connecting plate 112 is provided with a plurality of elastic elements 114. The outer wall of the top head 111 is slidably connected to the inside of the suction barrel 4. The outer wall of the connecting block 113 is slidably connected to the inner bottom wall of the suction barrel 4. One end of the elastic element 114 away from the connecting plate 112 is fixedly connected to the inside of the suction barrel 4. A plurality of magnetic blocks 14 are fixedly connected to the outer wall of the connecting plate 112. A magnetic block 25 is magnetically attracted to the side of the magnetic block 14 away from the connecting plate 112. The outer wall of the magnetic block 25 is fixedly connected to the inside of the suction barrel 4.

[0026] Specifically, after the sliding plate 9 moves upward a certain distance, it will come into contact with the top head 111, further driving the top head 111 to rotate. When the top head 111 rotates, it will drive the connecting plate 112 to rotate inside the suction barrel 4. At the same time, it will cooperate with the suction barrel 4 to compress the elastic element 114. The elastic element 114 is used to reset the connecting plate 112. When the connecting plate 112 rotates, it will drive the connecting block 113 to move upward, further driving the connecting rod 12 to move upward. Through the magnetic attraction of the opposite sides of the magnetic block 14 and the magnetic block 2 15, it is ensured that the sliding plate 9 continues to slide upward and disengage from the top head 111. After the sealing plug 13 resets and blocks the liquid outlet pipe 5, it will not be able to drain normally.

[0027] Please see the appendix Figure 3 Appendix Figure 5 and attached Figure 7The upper surface of the sliding plate 9 is attached to the base plate 16. Multiple transmission components 17 are fixedly mounted on the upper surface of the base plate 16. Each transmission component 17 includes a slide rod 173, the top end of which is fixedly connected to the lower surface of the partition plate 6. The transmission component 17 also includes a housing 171, the lower surface of which is fixedly connected to the upper surface of the base plate 16. A fixing frame 172 is fixedly mounted inside the housing 171, the lower surface of which is fixedly connected to the upper surface of the base plate 16. The outer wall of the slide rod 173 is slidably connected to the inner surfaces of the housing 171 and the fixing frame 172. The fixed frame 172 has a slider 174 slidably connected inside. The upper surface of the slider 174 is fixedly connected to the bottom end of the slide rod 173. The lower surface of the slider 174 is fixedly connected to an elastic element 175. The end of the elastic element 175 away from the slider 174 is fixedly connected to the inner bottom wall of the fixed frame 172. The slider 174 has a rotating plate 176 slidably connected inside. The end of the rotating plate 176 away from the slider 174 is rotatably connected to the inside of the fixed frame 172. The slider 174 has a groove 18 inside. The rotating plate 176 is slidably connected to the groove 18.

[0028] Specifically, after the sliding plate 9 moves upward a certain distance, it will contact the base plate 16, further driving the sliding rod 173 to slide inside the outer shell 171 and the fixing frame 172. When the sliding rod 173 slides, through the fixing action of the sliding rod 173 and the slider 174, the slider 174 will be driven to slide inside the fixing frame 172, and the elastic element 175 will be compressed at the same time. When the slider 174 slides, it will drive the rotating plate 176 to slide inside the slider 174 through the sliding groove 18. When the rotating plate 176 slides to the bottom of the sliding groove 18, the base plate 16 will seal the through hole opened inside the partition 6 to prevent the negative pressure inside the suction tank 4 from changing when draining the lower empty chamber 8, which would affect the effect of normal suction of intraoperative fluid.

[0029] Please see the appendix Figure 5 Appendix Figure 8 and attached Figure 9An air guiding assembly 19 is fixedly installed inside the sliding plate 9. The air guiding assembly 19 includes a fixed post 191, the outer wall of which is fixedly connected to the inside of the sliding plate 9. A sliding post 192 is slidably connected inside the fixed post 191. The top end of the sliding post 192 is attached to the lower surface of the partition plate 6. An elastic element 193 is fixedly installed on the outer wall of the sliding post 192 and is fixedly installed inside the fixed post 191. An airbag 194 is attached to the lower surface of the sliding post 192. The outer wall of the airbag 194 is fixedly installed inside the fixed post 191. An air guiding tube 20 is fixedly installed inside the airbag 194 and its outer wall is fixedly installed inside the fixed post 191. A sliding assembly 21 is installed at the end of the air guiding tube 20 away from the fixed post 191. Inside the moving plate 9; the sliding assembly 21 includes a fixed post 211, the outer wall of which is fixedly disposed inside the sliding plate 9. Multiple sliding posts 212 are slidably connected inside the fixed post 211. One end of each sliding post 212 is fixedly connected to an elastic element 213, and the other end is fixedly connected to a sealing plate 22. The sealing plate 22 is slidably connected inside the sliding plate 9. Multiple iron blocks 23 are fixedly connected inside the sliding plate 9. The sealing plate 22 is magnetically attracted to the outer wall of the iron blocks 23. Multiple magnetic blocks 25 are fixedly connected to the inner bottom wall of the suction barrel 4. Multiple grooves 24 are provided inside the sliding plate 9. The magnetic blocks 25 are slidably connected to the grooves 24. The sealing plate 22 and the magnetic blocks 25 are magnetically repelled on opposite sides. The magnetic blocks 25 have notches inside, the size of which is adapted to the connecting rod 12.

[0030] Specifically, a magnetic plate is provided on the side of the sealing plate 22 near the iron block 23, and the opposite side of the magnetic block 25 is magnetically repelled. When the sliding plate 9 moves upward through the through hole in the sealing partition 6, it cooperates with the partition 6 to squeeze the sliding column 192, causing it to slide downward inside the fixed column 191. At the same time, it cooperates with the fixed column 191 to stretch the elastic element 193. When the sliding column 192 slides downward, it squeezes the airbag 194, and the gas generated by squeezing the airbag 194 is transported to the fixed column 211 through the air guide pipe 20, further pushing the sliding column 212 inside it to move in the opposite direction. When the sliding column 212 moves, the fixing action of the sliding column 212 and the sealing plate 22 will drive the sealing plate 22 to move in the opposite direction. The sliding plate 9 slides inside and, after sliding a certain distance, attracts the iron block 23, further sealing the through hole inside the sliding plate 9. At this time, the electric push rod 10 drives the sliding plate 9 to move down and reset, thereby accelerating the drainage speed of the fluid inside the lower chamber 8. When the fluid inside the lower chamber 8 is completely drained and the sliding plate 9 returns to its initial position, the magnetic block 25 slides into the interior of the sliding plate 9 through the groove 24. The magnetic repulsion between the magnetic block 25 and the magnetic plate of the sealing plate 22 near the iron block 23 causes the sealing plate 22, the sealing plug 13, and the top head 111 to reset, further sealing the outlet pipe 5. The above steps are repeated, so that the intraoperative fluid can smoothly enter the lower chamber 8, ensuring the normal and stable operation of the fluid extraction operation during surgery.

[0031] Please see the appendix Figure 1 - Appendix Figure 9 The method of using the intraoperative targeted precision aspirator for effusion is as follows: S1. The electric push rod 10 is turned on, which drives the sliding plate 9 to move upward and further contact the top head 111 so that it rotates inside the suction barrel 4, thereby driving the connecting plate 112 and the connecting block 113 to rotate. When the connecting block 113 rotates, it will drive the connecting rod 12 to move upward, which will further drive the sealing plug 13 to move upward. S2. When the sliding plate 9 slides upward continuously, it will be in contact with the base plate 16, which will further drive the sliding rod 173 to slide inside the outer shell 171 and the fixed frame 172, thereby causing the slider 174 to slide inside the fixed frame 172. At this time, the rotating plate 176 will slide inside the slider 174 through the sliding groove 18, which will further drive the base plate 16 to slide inside the partition 6. S3. When the sliding plate 9 is in contact with the base plate 16, it will also cooperate with the partition plate 6 to make the sliding column 192 slide inside the fixed column 191 and compress the airbag 194 inside it. The gas generated by the compressed airbag 194 is delivered to the fixed column 211 through the air guide pipe 20, which further pushes the sliding column 212 to drive the sealing plate 22 to slide inside the sliding plate 9.

[0032] Workflow: After the sliding plate 9 moves upward a certain distance, it will contact the top head 111, thereby causing the top head 111 to rotate. When the top head 111 rotates, it will cause the connecting plate 112 to rotate, which will further cause the connecting block 113 to move upward. When the connecting block 113 moves upward, it will cause the connecting rod 12 to move upward, thereby causing the sealing plug 13 to slide out from the inside of the liquid outlet pipe 5, realizing the discharge of the liquid accumulated inside the lower empty chamber 8. While the connecting plate 112 is rotating, it will also be attracted by the magnetic attraction of the opposite sides of the magnetic block 14 and the magnetic block 2 15, ensuring that after the sliding plate 9 continues to slide upward and separates from the top head 111, the sealing plug 13 will not reset and block the liquid outlet pipe 5, thus avoiding affecting the normal liquid discharge effect.

[0033] After the sliding plate 9 moves upward a certain distance and contacts the base plate 16, it will drive the sliding rod 173 to slide inside the outer shell 171 and the fixing frame 172. When the sliding rod 173 slides, it will drive the slider 174 to slide inside the fixing frame 172. During the sliding process, the elastic element 175 is compressed. When the slider 174 slides, it will drive the rotating plate 176 to slide inside it. When the rotating plate 176 slides to the bottom of the slide groove 18, the base plate 16 will seal the through hole opened inside the partition 6. At this time, the upper empty chamber 7 is used to store the aspirated fluid, and the lower empty chamber 8 is drained. By sealing the partition 6, the negative pressure inside the suction tank 4 is prevented from changing when the lower empty chamber 8 drains, thus avoiding the effect of normal aspiration of the fluid during the operation.

[0034] A magnetic plate is installed on the side of the sealing plate 22 near the iron block 23, and it is magnetically repelled by the opposite side of the magnetic block 25. When the sliding plate 9 moves upward through the through hole in the sealing partition 6, it will cooperate with the partition 6, causing the sliding column 192 to slide downward inside the fixed column 191, while stretching the elastic element 193. When the sliding column 192 slides downward, it will squeeze the airbag 194 and deliver the generated gas to the fixed column 211 through the air guide tube 20, further pushing the sliding column 212 to move in the opposite direction. When the sliding column 212 moves, it will drive the sealing plate 22 to slide inside the sliding plate 9. After a certain distance, it will be attracted to the iron block 23, thereby sealing the through hole inside the sliding plate 9. At this time, the electric push rod 10 drives the sliding plate 9 to move down and reset, further accelerating the drainage speed of the liquid in the lower chamber 8. When the liquid is completely drained and the sliding plate 9 returns to its initial position, the magnetic block 25 will slide into the sliding plate 9 through the groove 24. By repelling the magnetic plate of the sealing plate 22, it further drives the sealing plate 22, the sealing plug 13 and the top head 111 to reset, sealing the liquid outlet pipe 5. Repeat the above steps to achieve the effect of allowing the intraoperative liquid to smoothly re-enter the lower chamber 8 without affecting the negative pressure inside the suction tank 4, ensuring the stable operation of the liquid extraction operation.

[0035] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
