Description

Technical Field

[0001] This invention relates to the field of drainage tube technology, and more specifically to an integrated drainage device for laparoscopic procedures in hepatobiliary surgery. Background Technology

[0002] Abdominal drainage tubes are important medical devices widely used after surgical procedures. They are mainly used to drain effusion, blood, pus, and other inflammatory exudates from the abdominal cavity to reduce postoperative infection, promote wound healing, and prevent the formation of effusion and encapsulated abscesses. In subsequent treatment, the abdominal drainage tube can also be used to directly deliver the required medications to the point of action. In actual clinical application, common problems such as drainage tube blockage, fluid leakage, difficulty in wound care leading to infection, and wound neuralgia are common, affecting the patient's postoperative experience, resulting in poor rest quality, directly affecting the postoperative recovery effect, and may even lead to serious complications.

[0003] The main problem with abdominal drainage tubes is that they are prone to blockage. Blockage is mainly caused by clots of blood, tissue fragments, fibrin, or purulent secretions entering and blocking the lumen or drainage hole of the drainage tube. Blockage can lead to poor drainage, resulting in ascites retention, increasing the risk of postoperative infection, and potentially causing problems such as increased intra-abdominal pressure and delayed wound healing.

[0004] Secondly, drainage tubes are difficult to clear. Once a traditional drainage tube becomes blocked, it is difficult to clear. In this case, medical staff usually need to remove the drainage tube and flush it manually, or replace it with a new drainage tube. However, this method can cause discomfort to the patient and may cause secondary trauma. In addition, the fluid that drips out when the drainage tube is removed can cause contamination on the patient or bed.

[0005] Therefore, in view of the problems that existing abdominal drainage tubes are prone to blockage and difficult to manually clear, the present invention provides an integrated drainage device for laparoscopic operation in hepatobiliary surgery to solve the above problems. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides an integrated drainage device for laparoscopic operation in hepatobiliary surgery to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] An integrated drainage device for laparoscopic hepatobiliary surgery includes a protective plate with adhesive tape on both sides. A drainage tube through-hole is penetrating the middle of the protective plate. A protective outer tube, coaxial with the drainage tube through-hole, is installed on the top of the protective plate. A drainage tube is inserted into the protective outer tube. Multiple circumferentially distributed drainage grooves are penetrating the bottom end of the drainage tube. A handle is installed on the top of the drainage tube. A flushing tube is penetrating and installed in the middle of the handle. A flushing tube through-hole is penetrating the middle of the bottom end of the drainage tube. The bottom end of the flushing tube extends from the flushing tube through-hole to below the bottom end of the drainage tube. Multiple flushing holes are penetrating the bottom end of the flushing tube. A drainage connecting tube is connected to the outer wall of the handle.

[0009] Preferably, a spring top plate is fixedly installed on the inner side of the top of the drainage tube, and a cross-shaped spring compression plate is fixedly installed on the outer side of the flushing tube inside the drainage tube. A flushing tube spring is installed inside the drainage tube between the spring top plate and the spring compression plate. When the flushing tube moves upward axially, it can drive the spring compression plate to compress the flushing tube spring upward.

[0010] Preferably, the bottom end of the flushing tube spring is fixedly connected to the top surface of the spring compression plate, the top end of the flushing tube spring is movably abutting against the bottom surface of the spring top plate, the flushing tube spring abuts against the inner wall of the drainage tube, and when the spring compression plate rotates, it can drive the flushing tube spring to rotate along the inner wall of the drainage tube to clean the inner wall of the drainage tube.

[0011] Preferably, the spring top plate has a through-hole for drainage connection, and one end of the drainage connection tube extends into the interior of the handheld part and is connected to the drainage connection hole.

[0012] Preferably, a spiral sawtooth strip located outside the flushing pipe is fixedly installed on the bottom surface of the spring extrusion plate. The spiral sawtooth strip abuts against the inner wall of the drainage pipe, and the spiral sawtooth strip rotates when the spring extrusion plate rotates.

[0013] Preferably, anti-clogging silicone strips are fixedly installed on the outer surface of the bottom end of the drainage tube, located on both sides of each drainage groove, to prevent the drainage groove from becoming blocked.

[0014] Preferably, a barrier net is installed on the bottom surface of the spring compression plate.

[0015] Preferably, the outer surface of the top end of the drainage tube is provided with a drainage tube external thread, the inner side of the top end of the protective outer tube is provided with a threaded feed groove, a drainage tube threaded sleeve is installed on the outer thread of the drainage tube external thread, a positioning external thread is provided on the outer surface of the top end of the protective outer tube, and a positioning threaded sleeve that can be threaded with the positioning external thread is fixedly installed at the bottom of the drainage tube threaded sleeve.

[0016] Preferably, a flushing pipe operating block is fixedly installed on the outer side of the top end of the flushing pipe, and an external thread of the flushing pipe is provided on the outer side of the top end of the flushing pipe below the flushing pipe operating block. A flushing pipe threaded sleeve is installed on the outer thread of the external thread of the flushing pipe, and a flushing protection pipe coaxial with the flushing pipe through hole is fixedly installed on the inner wall of the bottom end of the drainage pipe.

[0017] Preferably, the bottom surface of the protective plate is provided with a protective groove, and two protective sliding grooves are respectively located on the left and right sides of the drainage pipe through hole between the protective groove and the top surface of the protective plate. A protective slider is slidably installed in each protective sliding groove, and a rubber sheet located inside the protective groove is fixedly installed at the bottom end of each protective slider. A groove cover is installed at the opening of the protective groove, and the groove cover has a through hole in the middle, and a seepage-proof silicone ring is fixedly installed at the bottom end of the through hole.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. After the drainage tube is inserted into the protective outer tube, it can continue to be inserted into the drainage wound through the drainage tube through hole for drainage. When removing the drainage tube, move the drainage tube into the protective outer tube to prevent the fluid brought out by the outside of the drainage tube from dripping onto the patient. Irrigation is performed through multiple irrigation holes to irrigate the abdominal cavity. When irrigation is not needed, the irrigation tube can be pulled upwards so that its bottom end moves from the irrigation tube through hole into the drainage tube. When the bottom end of the irrigation tube moves upwards, the irrigation tube through hole can scrape off the fluid adhering to the outside of the irrigation tube, thereby keeping the outside of the irrigation tube clean.

[0020] 2. When the flushing tube moves upward axially, it can drive the spring compression plate to compress the flushing tube spring upward. When the flushing tube is released, the flushing tube spring is released, which can drive the spring compression plate to return to its original position downward. This allows the flushing tube to extend from the flushing tube through hole to the bottom of the drainage tube. When the inner wall of the drainage tube is covered with blood clots or tissue, the flushing tube can be rotated to drive the spring compression plate to rotate. When the spring compression plate rotates, it can drive the flushing tube spring to rotate against the inner wall of the drainage tube, and can scrape off the blood clots and other objects adhering to the inner wall of the drainage tube, so that the blood clots and other objects can be attracted into the drainage bag. This achieves the cleaning of the inner wall of the drainage tube and avoids the blood clots, tissue, and other objects from clogging the drainage tube.

[0021] 3. When there are blood clots, tissues, or other objects in the effusion, the flushing tube can be rotated to drive the spring squeeze plate to rotate. When the spring squeeze plate rotates, it drives the spiral saw blade to rotate. The spiral saw blade can break up the blood clots, tissues, and other objects. At the same time, when the spiral saw blade rotates, it can also scrape off the effusion, blood clots, and other objects adhering to the inner wall of the drainage tube, thereby preventing the blood clots, tissues, and other objects from clogging the drainage tube.

[0022] 4. After the drainage tube is inserted to the specified depth, the drainage tube sleeve can be screwed to move towards the protective outer tube, thereby making the positioning sleeve threadedly connected with the positioning external thread to fix the drainage tube. When flushing is not required, the flushing tube sleeve can be screwed to move the flushing tube upward and position it, preventing the flushing tube from moving downward to the outside of the drainage tube under the elastic force of the flushing tube spring. A flushing protection tube coaxial with the flushing tube through hole is fixedly installed on the inner wall of the bottom end of the drainage tube. When the flushing tube enters the drainage tube, its bottom end is inside the flushing protection tube. The inner wall of the flushing protection tube fits against the outer wall of the flushing tube, which can block multiple flushing holes and prevent liquid from entering the flushing tube and causing pollution.

[0023] 5. When drainage is completed or the drainage tube needs to be replaced, the bottom end of the drainage tube can be moved into the protective outer tube. Then, the two protective sliders can be moved towards the protective outer tube, causing the two rubber sheets to close together in the middle, thereby closing and sealing the drainage tube through hole and preventing the accumulated fluid adhering to the outside of the bottom end of the drainage tube from dripping down. The anti-seepage silicone ring can be placed inside the drainage wound. When the drainage tube is inserted into the drainage wound through the drainage tube through hole, the drainage tube can expand the anti-seepage silicone ring into a cylindrical shape, so that the outer wall of the anti-seepage silicone ring fits against the drainage wound, thereby preventing seepage at the drainage wound.

[0036] The following will refer to the appendix. Figures 1-11 The description provides a detailed description of various embodiments of the present invention.

[0037] An integrated drainage device for laparoscopic procedures in hepatobiliary surgery, as shown in the attached... Figure 1-11As shown, the device includes a protective plate 1, which is made of rigid material and can be covered with a soft leather or silicone layer. Adhesive tape 2 is provided on both sides of the protective plate 1. A drainage tube through-hole 3 penetrates the center of the protective plate 1. The protective plate 1 can be attached to the location requiring drainage using the adhesive tape 2, aligning the drainage tube through-hole 3 with the drainage wound. The protective plate 1 can shield and protect the drainage wound, preventing leakage. A protective outer tube 4, coaxial with the drainage tube through-hole 3, is installed on the top of the protective plate 1. The protective outer tube 4 is inserted into... A drainage tube 5 is installed inside the protective outer tube 4. After the drainage tube 5 is inserted, it can continue to be inserted into the drainage wound through the drainage tube through hole 3 for drainage. When removing the drainage tube 5, it is moved inside the protective outer tube 4 to prevent the accumulated fluid brought out by the outside of the drainage tube 5 from dripping onto the patient. The bottom end of the drainage tube 5 has multiple circumferentially evenly distributed drainage grooves 6. The accumulated fluid is drawn into the drainage tube 5 through the drainage grooves 6 and then suctioned out of the patient's body. The top tube of the drainage tube 5 is equipped with a handle 7, which allows medical staff to... The handheld part 7 is used for operation. A flushing tube 8 is installed through and attached to the middle of the handheld part 7. A syringe can be connected to the top of the flushing tube 8. Cleaning fluid is injected into the flushing tube 8 through the syringe to flush the abdominal cavity. The fluid is then aspirated through the drainage tube 5. A flushing tube through-hole 9 passes through the middle of the bottom end of the drainage tube 5. The bottom end of the flushing tube 8 extends from the flushing tube through-hole 9 to below the bottom end of the drainage tube 5. Multiple flushing holes 10 pass through the bottom end of the flushing tube 8. The flushing tube through-hole 9 fits snugly against the outer wall of the flushing tube 8. 8. The abdominal cavity is flushed through multiple flushing holes 10. When flushing is not required, the flushing tube 8 can be pulled upward so that its bottom end moves from the flushing tube through hole 9 into the drainage tube 5. When the bottom end of the flushing tube 8 moves upward, the flushing tube through hole 9 can scrape off the accumulated fluid on the outside of the flushing tube 8, thereby keeping the outside of the flushing tube 8 clean. The outer wall of the handheld part 7 is connected to a drainage connecting tube 11. The drainage connecting tube 11 can be connected to a negative pressure drainage bag or a drainage machine, thereby providing the suction required for drainage to the drainage tube 5.

[0038] As attached Figures 4-11 As shown, a spring top plate 12 is fixedly installed on the inner side of the top of the drainage tube 5. A cross-shaped spring compression plate 13 is fixedly installed on the outer side of the flushing tube 8 inside the drainage tube 5. When the flushing tube 8 is pulled upward, the spring compression plate 13 can be moved upward. When the flushing tube 8 is rotated, the spring compression plate 13 can be rotated. A flushing tube spring 14 is installed inside the drainage tube 5 between the spring top plate 12 and the spring compression plate 13. When the flushing tube 8 moves upward axially, the spring compression plate 13 can be driven upward to compress the flushing tube spring 14. When the flushing tube 8 is released, the flushing tube spring 14 is released, which can drive the spring compression plate 13 to return to its original position downward, thereby driving the flushing tube 8 to extend from the flushing tube through hole 9 to the bottom of the drainage tube 5.

[0039] As attached Figures 4-11 As shown, the bottom end of the flushing tube spring 14 is fixedly connected to the top surface of the spring compression plate 13, the top end of the flushing tube spring 14 is movably abutting against the bottom surface of the spring top plate 12, and the flushing tube spring 14 abuts against the inner wall of the drainage tube 5. When the inner wall of the drainage tube 5 is covered with blood clots or tissue, the flushing tube 8 can be rotated to drive the spring compression plate 13 to rotate. When the spring compression plate 13 rotates, it can drive the flushing tube spring 14 to rotate against the inner wall of the drainage tube 5, and can scrape off the blood clots and other objects adhering to the inner wall of the drainage tube 5, so that the blood clots and other objects can be attracted into the drainage bag, thereby cleaning the inner wall of the drainage tube 5 and preventing blood clots, tissue, and other objects from clogging the drainage tube 5.

[0040] As attached Figure 9 As shown, a drainage connection hole 15 is provided through the spring top plate 12. One end of the drainage connection tube 11 extends into the interior of the handheld part 7 and is connected to the drainage connection hole 15. When the drainage connection tube 11 is connected to a negative pressure drainage bag or a negative pressure device, a negative pressure can be generated inside the drainage tube 5 to drain the accumulated liquid.

[0041] As attached Figures 7-8 As shown, a spiral serrated strip 16 located outside the flushing pipe 8 is fixedly installed on the bottom surface of the spring squeeze plate 13. The spiral serrated strip 16 has serrations on its surface and abuts against the inner wall of the drainage pipe 5. When there are blood clots, tissues, or other objects in the accumulated fluid, the blood clots and tissues enter the drainage pipe 5 from the drainage groove 6 and are intercepted by the blocking net 18. The flushing pipe 8 can be rotated to drive the spring squeeze plate 13 to rotate. When the spring squeeze plate 13 rotates, it drives the spiral serrated strip 16 to rotate. The spiral serrated strip 16 can then break up the blood clots, tissues, and other objects. At the same time, when the spiral serrated strip 16 rotates, it can also scrape off the accumulated fluid, blood clots, and other objects adhering to the inner wall of the drainage pipe 5, thereby preventing the blood clots, tissues, and other objects from clogging the drainage pipe 5.

[0042] As attached Figure 6 As shown, anti-blocking silicone strips 17 are fixedly installed on the outer side of the bottom end of the drainage tube 5, located on both sides of each drainage groove 6. The anti-blocking silicone strips 17 can support and separate the drainage groove 6 from the abdominal wall, so as to prevent the abdominal wall from blocking the drainage groove 6 and affecting the normal drainage process.

[0043] As attached Figure 8 As shown, a barrier net 18 is installed on the bottom surface of the spring compression plate 13. The barrier net 18 can intercept blood clots, tissues, etc., and then the spiral saw 16 can be rotated to crush the blood clots, tissues, etc.

[0044] As attached Figures 1-3 , Figure 10As shown, the outer surface of the top end of the drainage tube 5 is provided with a drainage tube external thread 19, and the inner side of the top end of the protective outer tube 4 is provided with a threaded feed groove 20. When the drainage tube 5 is inserted into the abdominal cavity, the drainage tube external thread 19 on its outer side can enter the threaded feed groove 20. A drainage tube threaded sleeve 21 is installed on the outer thread of the drainage tube external thread 19. A positioning external thread 22 is provided on the outer surface of the top end of the protective outer tube 4. A positioning threaded sleeve 23 that can be threadedly engaged with the positioning external thread 22 is fixedly installed at the bottom of the drainage tube threaded sleeve 21. When the drainage tube 5 is inserted to a specified depth, the drainage tube threaded sleeve 21 can be screwed to move towards the protective outer tube 4, so that the positioning threaded sleeve 23 is threadedly connected with the positioning external thread 22, thereby fixing the drainage tube 5.

[0045] As attached Figures 1-3 , Figure 9 As shown, an irrigation tube operating block 24 is fixedly installed on the outer surface of the top end of the irrigation tube 8. Medical personnel can pull the irrigation tube operating block 24 to pull the irrigation tube 8 upward, or rotate the irrigation tube operating block 24 to rotate the irrigation tube 8. An external thread 25 of the irrigation tube is provided on the outer surface of the top end of the irrigation tube 8, located below the irrigation tube operating block 24. The external thread 25 of the irrigation tube can move axially within the through hole at the top of the handle 7. An irrigation tube thread sleeve 26 is installed on the outer thread of the external thread 25 of the irrigation tube. When the irrigation tube 8 is not needed for irrigation, it can be screwed off. The flushing pipe sleeve 26 moves the flushing pipe 8 upward and positions it so that the flushing pipe 8 will not move downward to the outside of the drainage pipe 5 under the elastic force of the flushing pipe spring 14. A flushing protection pipe 33 coaxial with the flushing pipe through hole 9 is fixedly installed on the inner wall of the bottom end of the drainage pipe 5. When the flushing pipe 8 enters the drainage pipe 5, its bottom end is inside the flushing protection pipe 33. The inner wall of the flushing protection pipe 33 fits against the outer wall of the flushing pipe 8, which can block the multiple flushing holes 10 and prevent the accumulated liquid from entering the flushing pipe 8 and causing pollution.

[0046] As attached Figure 11As shown, the bottom surface of the protective plate 1 has a protective groove 27. Two protective sliding grooves 28, located on the left and right sides of the drainage pipe through hole 3, pass through the protective groove 27 and the top surface of the protective plate 1. A protective slider 29 is slidably installed in each protective sliding groove 28, and there is friction between the protective slider 29 and the protective sliding groove 28. A rubber sheet 30 located inside the protective groove 27 is fixedly installed at the bottom end of each protective slider 29. When drainage is completed, or when the drainage pipe 5 needs to be replaced, the bottom end of the drainage pipe 5 can be moved into the outer protective pipe 4, and then the two protective sliders 29 can be moved towards the outer protective pipe 4, causing the two rubber sheets 30 to move towards the center. The drainage tube through-hole 3 is closed and sealed to prevent the accumulated fluid adhering to the outer side of the bottom of the drainage tube 5 from dripping. A groove cover 31 is installed at the opening of the protective groove 27. The groove cover 31 has a through hole in the middle, and a leak-proof silicone ring 32 is fixedly installed at the bottom of the through hole. The leak-proof silicone ring 32 is closed when not in use. When the protective plate 1 is attached to the patient's skin, the leak-proof silicone ring 32 can be placed inside the drainage wound. When the drainage tube 5 is inserted into the drainage wound through the drainage tube through-hole 3, the drainage tube 5 can expand the leak-proof silicone ring 32 into a cylindrical shape, so that the outer wall of the leak-proof silicone ring 32 fits against the drainage wound, thereby avoiding the occurrence of seepage at the drainage wound.
