Description

TECHNICAL FIELD

[0001] The present application relates to the field of hepatobiliary and pancreatic surgery drainage technology, in particular to a novel hepatobiliary and pancreatic surgery drainage device. BACKGROUND

[0002] Hepatobiliary and pancreatic surgery drainage is a technique that places a drainage tube in the hepatobiliary and pancreatic system through surgery or minimally invasive methods to guide pathological bile, pus, necrotic tissue or exudate out of the body to relieve obstruction, control infection and promote healing. The core of this technique is to maintain the patency of the pipeline, reduce internal pressure and create favorable conditions for disease treatment. In hepatobiliary and pancreatic surgery, hepatobiliary and pancreatic drainage devices are used to drain bile or pus from the patient's body. Currently used hepatobiliary and pancreatic surgery drainage devices generally use a method of squeezing a drainage ball to drain bile or pus. However, the negative pressure generated by the drainage ball has weak stability, and in use, the negative pressure can be easily attenuated due to the resistance of the catheter to the fluid, thereby reducing the drainage efficiency or causing insufficient negative pressure. SUMMARY

[0010] Further, the surface of the moving ring is in contact with the inner wall of the drainage frame, one end of the linkage rod away from the moving ring penetrates through the drainage frame and extends below the drainage frame, and the surface of the cleaning ring and the inner wall of the drainage frame are provided with a distance.

[0012] Further, the extrusion part comprises a positioning plate, the surface of the positioning plate is fixedly connected with the surface of the drainage frame, the surface of the positioning plate is slidingly connected with a sliding frame, the lower surface of the drainage frame is communicated with a discharge pipe, the surface of the discharge pipe is fixedly connected with a disc, the surface of the discharge pipe is inserted with a liquid storage bag, the surface of the discharge pipe is provided with an extrusion ring, the top of the extrusion ring is hingedly connected with an elastic rod, one end of the elastic rod away from the extrusion ring is hingedly connected with the surface of the sliding frame, and the inner wall of the lifting ring is provided with an extrusion hole.

[0014] The present application has the following beneficial effects: This invention involves placing the catheter in the area requiring treatment on the patient, then pushing the lifting ring to slide on the surface of the drainage frame. As the lifting ring slides downwards, it pushes the curved frame downwards via a rotating ring. The sliding rod, through the movement of the curved frame, pushes the pressure plate to move inside the negative pressure frame. The pressure plate generates negative pressure as it moves inside the negative pressure frame. This negative pressure is transmitted to the inside of the catheter through a ball valve and connecting tube. The catheter drains pus from the patient's body through this negative pressure. The downward movement of the pressure plate inside the negative pressure frame further enhances the stability of the negative pressure provided by the frame. Pus entering the negative pressure frame enters the drainage frame through a leak hole. A storage bag is used to store the pus inside the drainage frame, preventing backflow and potential harm to the patient. The negative pressure generated by the frame directly enters the inside of the catheter through the connecting tube, further improving the stability of the negative pressure provided by the frame. The catheter and connecting tube are connected by a plug-in joint for easy catheter replacement. The drainage frame is isolated from the patient through the catheter, ensuring that the drainage frame will not cause infection when reused.

[0015] This invention features a perforated plate inside the pressure plate to limit the movement of the plumb rod. When the pressure plate moves upward inside the negative pressure frame, the friction between the friction plate and the inner wall of the frame pulls the plumb rod downward. The plumb rod then pulls the sealing plate away from the inner wall of the circular hole. At this time, the circular hole is open when the pressure plate moves upward. With the circular hole open, the pressure plate does not generate thrust when moving upward, preventing the pus from flowing back into the conduit. The pus at the top of the pressure plate also flows through the circular hole and the perforated plate into the lower part of the negative pressure frame for discharge. When the pressure plate moves downward, the friction plate pushes the plumb rod upward through friction. The sealing plate contacts the inner wall of the circular hole as the plumb rod moves, sealing it. At this time, the downward movement of the pressure plate generates negative pressure to drain the pus, improving the practicality of the negative pressure frame. When the conduit becomes blocked during drainage, the pressure plate moves inside the negative pressure frame to provide negative pressure, improving the drainage efficiency of the conduit. The movement of the pressure plate during drainage does not cause backflow.

[0016] When the drainage frame needs cleaning, the present invention adds cleaning fluid to the inside of the drainage frame and the negative pressure frame through a connecting pipe, pushing the lifting ring to move back and forth on the surface of the drainage frame. When the lifting ring moves, it pushes the moving ring to move inside the drainage frame through a connecting rod. The moving ring cleans the inner wall of the drainage frame. When the pressure plate moves inside the negative pressure frame, it cleans the inner wall of the negative pressure frame. When the moving ring contacts the surface of the cleaning ring, the rotating ring is twisted to rotate back and forth on the surface of the lifting ring. When the moving ring rotates, it drives the cleaning ring to rotate through friction. When the cleaning ring rotates, it cleans the inner wall of the drainage frame through the cleaning plate. This improves the convenience of cleaning the inner wall of the drainage frame and facilitates the multiple uses of the drainage frame.

[0017] When the lifting ring moves downward, the inner wall of the extrusion hole contacts the surface of the positioning plate. The lifting ring pushes the sliding frame downward. When the sliding frame moves downward, the elastic rod pushes the extrusion ring to extrude the liquid storage bag. After being extruded, the liquid storage bag will extrude the disc. The extrusion ring fixes the liquid storage bag on the surface of the disc, improving the stability of the liquid storage bag after installation. When the elastic rod is perpendicular to the positioning plate, the sliding frame is positioned by the pressure of the elastic rod, so that the elastic rod will remain perpendicular to the positioning plate to extrude the extrusion ring, improving the stability of the liquid storage bag during operation.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-9 As shown, the present invention is a novel surgical drainage device for hepatobiliary and pancreatic surgery, including a drainage frame 1, a ball valve 4 connected to the top of the drainage frame 1, a connecting pipe 5 connected to the top of the ball valve 4, a catheter 3 inserted into the surface of the connecting pipe 5, and a drainage component 6 provided inside the drainage frame 1. The drainage component 6 includes a negative pressure frame 10. The top of the negative pressure frame 10 is fixedly connected to the top of the inner wall of the drainage frame 1. A limit plate 11 is fixedly connected to the surface of the drainage frame 1. A lifting ring 16 is slidably connected to the surface of the drainage frame 1. A rotating ring 12 is rotatably connected to the surface of the lifting ring 16. A curved frame 15 is fixedly connected to the surface of the rotating ring 12. A sliding rod 14 is fixedly connected to the end of the curved frame 15 away from the rotating ring 12. A pressure plate 17 is fixedly connected to the top of the sliding rod 14. After the catheter 3 is placed in the area where the patient needs treatment, the lifting ring 16 is pushed to slide on the surface of the drainage frame 1. When the lifting ring 16 slides downward, it pushes the curved frame 15 downward through the rotating ring 12. The sliding rod 14 pushes the pressure plate 17 to move inside the negative pressure frame 10 through the movement of the curved frame 15. When the pressure plate 17 moves inside the negative pressure frame 10, it generates negative pressure. The negative pressure is transmitted to the catheter through the ball valve 4 and the connecting tube 5. Inside the catheter 3, the negative pressure drains the pus from the patient's body. When the pressure plate 17 moves downward inside the negative pressure frame 10, it generates negative pressure, improving the stability of the negative pressure provided by the negative pressure frame 10. The pus entering the negative pressure frame 10 will enter the drainage frame 1 through the leakage hole 13. The pus inside the drainage frame 1 is stored by the storage bag 2 to prevent the pus from flowing back into the patient's body and causing harm. The negative pressure generated by the negative pressure frame 10 directly enters the inside of the catheter 3 through the connecting tube 5, further improving the stability of the negative pressure provided by the negative pressure frame 10. The catheter 3 and the connecting tube 5 are connected by a plug-in design, which facilitates the replacement of the catheter 3. The drainage frame 1 is isolated from the patient through the catheter 3. The lower surface of the negative pressure frame 10 is provided with a leakage hole 13. The surface of the pressure plate 17 is provided with an opening and closing component 7. The inside of the drainage frame 1 is provided with a cleaning component 8. The surface of the drainage frame 1 is provided with a squeezing component 9.

[0024] There are four limiting plates 11, which are arranged in a circle around the center of the diversion frame 1. The inner wall of the lifting ring 16 is slidably connected to the surface of the limiting plates 11. The end of the bending frame 15 away from the rotating ring 12 extends to the bottom of the diversion frame 1.

[0025] The top of the slide bar 14 passes through the drainage frame 1 and extends into the interior of the negative pressure frame 10. The surface of the pressure plate 17 contacts the inner wall of the negative pressure frame 10. The top of the negative pressure frame 10 is connected to the ball valve 4.

[0026] The opening / closing component 7 includes a circular hole 21, which is located at the top of the pressure plate 17. A limiting hole 20 is located at the bottom of the pressure plate 17. A through-hole plate 23 is fixedly connected to the inner wall of the limiting hole 20. A sealing plate 22 is located at the top of the through-hole plate 23, and a vertical rod 24 is fixedly connected to the bottom of the sealing plate 22. A connecting plate 25 is fixedly connected to the lower surface of the vertical rod 24. A friction plate 26 is fixedly connected to the end of the connecting plate 25 away from the vertical rod 24. The through-hole plate 23 inside the pressure plate 17 limits the vertical rod 24. When the pressure plate 17 moves upward inside the negative pressure frame 10, the friction between the friction plate 26 and the inner wall of the negative pressure frame 10 pulls the vertical rod 24 downward. The vertical rod 24 pulls the sealing plate 22 away from the inner wall of the circular hole 21, at which point the pressure plate 17 moves upward. When the pressure plate 17 moves upward, the circular hole 21 is in the open state. When the circular hole 21 is open, the pressure plate 17 will not generate thrust when it moves upward, thus preventing the pus from flowing back inside the conduit 3. The pus at the top of the pressure plate 17 will also flow into the lower part of the negative pressure frame 10 through the circular hole 21 and the through-hole plate 23 for discharge. When the pressure plate 17 moves downward, the friction plate 26 will push the vertical rod 24 upward through friction. The sealing plate 22 will contact the inner wall of the circular hole 21 and seal it as the vertical rod 24 moves. At this time, when the pressure plate 17 moves downward, it will generate negative pressure to drain the pus, improving the practicality of the negative pressure frame 10. When the conduit 3 becomes blocked during the drainage process, it will push the pressure plate 17 to move inside the negative pressure frame 10 to provide negative pressure.

[0027] The bottom of the round hole 21 is connected to the top of the limiting hole 20. The sealing plate 22 is located inside the limiting hole 20. The surface of the sealing plate 22 is in contact with the inner wall of the round hole 21. The bottom of the vertical rod 24 passes through the through hole plate 23 and extends to the bottom of the through hole plate 23. The end of the friction plate 26 away from the connecting plate 25 is in contact with the inner wall of the negative pressure frame 10.

[0028] The cleaning component 8 includes a movable ring 30, the inner wall of which contacts the inner wall of the negative pressure frame 10. A connecting rod 31 is fixedly connected to the bottom of the movable ring 30, and the end of the connecting rod 31 away from the movable ring 30 is fixedly connected to the surface of the bending frame 15. A cleaning ring 33 is provided at the bottom of the inner wall of the drainage frame 1. The bottom of the cleaning ring 33 has multiple rectangular holes 34. A cleaning plate 32 is fixedly connected to the surface of the cleaning ring 33. When the drainage frame 1 needs to be cleaned, cleaning fluid is added to the inside of the drainage frame 1 and the negative pressure frame 10 through the connecting pipe 5, which pushes the lifting ring 16 to the drainage frame. The surface of frame 1 moves back and forth. When the lifting ring 16 moves, it pushes the moving ring 30 to move inside the drainage frame 1 through the linkage rod 31. The moving ring 30 cleans the inner wall of the drainage frame 1. When the pressure plate 17 moves inside the negative pressure frame 10, it cleans the inner wall of the negative pressure frame 10. When the moving ring 30 contacts the surface of the cleaning ring 33, the rotating ring 12 is twisted and rotates back and forth on the surface of the lifting ring 16. When the moving ring 30 rotates, it drives the cleaning ring 33 to rotate through friction. When the cleaning ring 33 rotates, it cleans the inner wall of the drainage frame 1 through the cleaning plate 32.

[0029] The surface of the moving ring 30 contacts the inner wall of the drainage frame 1, and the end of the linkage rod 31 away from the moving ring 30 passes through the drainage frame 1 and extends to the bottom of the drainage frame 1. The surface of the cleaning ring 33 is provided with a distance from the inner wall of the drainage frame 1.

[0030] The bottom of the cleaning plate 32 contacts the bottom of the inner wall of the drainage frame 1, the end of the cleaning plate 32 contacts the inner wall of the drainage frame 1, the end of the cleaning plate 32 away from the drainage frame 1 contacts the surface of the slide bar 14, and the surface of the cleaning ring 33 is adapted to the inner wall of the moving ring 30.

[0031] The extrusion component 9 includes a positioning plate 41, the surface of which is fixedly connected to the surface of the drainage frame 1. A sliding frame 40 is slidably connected to the surface of the positioning plate 41. A discharge pipe 44 is connected to the lower surface of the drainage frame 1. A disc 45 is fixedly connected to the surface of the discharge pipe 44. A liquid storage bag 2 is inserted into the surface of the discharge pipe 44. An extrusion ring 43 is provided on the surface of the discharge pipe 44. A spring rod 42 is hinged to the top of the extrusion ring 43. The end of the spring rod 42 away from the extrusion ring 43 is hinged to the surface of the sliding frame 40. An extrusion hole is provided on the inner wall of the lifting ring 16. When the lifting ring 16 moves downward, the inner wall of the extrusion hole will contact the positioning plate 41. The surface of plate 41 contacts the sliding frame 40, which is pushed downward by lifting ring 16. When the sliding frame 40 moves downward, it pushes squeezing ring 43 through elastic rod 42 to squeeze the liquid storage bag 2. After being squeezed, the liquid storage bag 2 will squeeze the disc 45. The squeezing ring 43 is used to fix the liquid storage bag 2 on the surface of the disc 45, improving the stability of the liquid storage bag 2 after installation. When the elastic rod 42 is perpendicular to the positioning plate 41, the sliding frame 40 is positioned by the pressure of the elastic rod 42, so that the elastic rod 42 will remain perpendicular to the positioning plate 41 to squeeze the squeezing ring 43.

[0032] The inner wall of the extrusion hole is adapted to the surface of the positioning plate 41, the inner wall of the extrusion ring 43 is spaced from the surface of the discharge pipe 44, the inner wall of the extrusion ring 43 is in contact with the surface of the liquid storage bag 2, and the inner wall of the liquid storage bag 2 is in contact with the surface of the disc 45.

[0033] In use, after placing the catheter 3 in the area where the patient needs treatment, push the lifting ring 16 to slide on the surface of the drainage frame 1. When the lifting ring 16 slides downward, it pushes the curved frame 15 downward through the rotating ring 12. The sliding rod 14 pushes the pressure plate 17 to move inside the negative pressure frame 10 through the movement of the curved frame 15. When the pressure plate 17 moves inside the negative pressure frame 10, it generates negative pressure. The negative pressure is transmitted to the inside of the catheter 3 through the ball valve 4 and the connecting pipe 5. The catheter 3 drains the pus from the patient's body through the negative pressure. When the pressure plate 17 moves downward inside the negative pressure frame 10, it generates negative pressure, improving the stability of the negative pressure provided by the negative pressure frame 10. The pus entering the inside of the negative pressure frame 10 will enter the inside of the drainage frame 1 through the leakage hole 13. The reservoir bag 2 is used to regulate the drainage inside the drainage frame 1. The pus is stored to prevent it from flowing back into the patient's body and causing harm. The negative pressure generated by the negative pressure frame 10 directly enters the interior of the catheter 3 through the connecting tube 5, further improving the stability of the negative pressure provided by the negative pressure frame 10. The catheter 3 and the connecting tube 5 are connected by an insertion device, which facilitates the replacement of the catheter 3. The drainage frame 1 is isolated from the patient through the catheter 3, so that the drainage frame 1 will not cause infection when reused. A through-hole plate 23 is provided inside the pressure plate 17 to limit the vertical rod 24. When the pressure plate 17 moves upward inside the negative pressure frame 10, the friction plate 26 and the inner wall of the negative pressure frame 10 will pull the vertical rod 24 downward. The vertical rod 24 pulls the sealing plate 22 away from the inner wall of the round hole 21. At this time, when the pressure plate 17 moves upward, the round hole 21 will be closed. With hole 21 open, the pressure plate 17 will not generate thrust when it moves upward, preventing backflow of pus inside the catheter 3. Pus at the top of the pressure plate 17 will also flow through hole 21 and through-hole plate 23 into the lower part of the negative pressure frame 10 for discharge. When the pressure plate 17 moves downward, the friction plate 26 will push the vertical rod 24 upward through friction. The sealing plate 22, along with the movement of the vertical rod 24, contacts the inner wall of hole 21 to seal it. At this time, the downward movement of the pressure plate 17 will generate negative pressure to drain the pus, improving the practicality of the negative pressure frame 10. When the catheter 3 becomes blocked during drainage, the pressure plate 17 is pushed to move inside the negative pressure frame 10 to provide negative pressure. To improve the drainage efficiency of catheter 3, the pressure plate 17 is moved during drainage without causing backflow. When cleaning the drainage frame 1 is required, cleaning fluid is added to the drainage frame 1 and the negative pressure frame 10 through the connecting pipe 5, pushing the lifting ring 16 to move back and forth on the surface of the drainage frame 1. When the lifting ring 16 moves, it pushes the moving ring 30 to move inside the drainage frame 1 through the connecting rod 31, using the moving ring 30 to clean the inner wall of the drainage frame 1. When the pressure plate 17 moves inside the negative pressure frame 10, it cleans the inner wall of the negative pressure frame 10. When the moving ring 30 contacts the surface of the cleaning ring 33, the rotating ring 12 is twisted and rotated back and forth on the surface of the lifting ring 16. When the moving ring 30 rotates, it drives the cleaning ring 33 to rotate through friction.When the cleaning ring 33 rotates, it cleans the inner wall of the drainage frame 1 through the cleaning plate 32, improving the convenience of cleaning the inner wall of the drainage frame 1 and facilitating multiple uses of the drainage frame 1. When the lifting ring 16 moves downward, the inner wall of the squeezing hole will contact the surface of the positioning plate 41. The lifting ring 16 pushes the sliding frame 40 downward. When the sliding frame 40 moves downward, it pushes the squeezing ring 43 through the elastic rod 42 to squeeze the liquid storage bag 2. After being squeezed, the liquid storage bag 2 will squeeze the disc 45. The squeezing ring 43 fixes the liquid storage bag 2 to the surface of the disc 45, improving the stability of the liquid storage bag 2 after installation. When the elastic rod 42 is perpendicular to the positioning plate 41, the sliding frame 40 is positioned by the pressure of the elastic rod 42, so that the elastic rod 42 will remain perpendicular to the positioning plate 41 to squeeze the squeezing ring 43, improving the stability of the liquid storage bag 2 during operation.
