[0001] The invention relates to the technical field of incision drainage, in particular to a novel drainage device for breast surgery. Background Art

[0002] Breast surgical drainage is a procedure used to treat breast-related diseases, especially breast effusion or abscess. The main purpose is to drain the pathological fluid in the breast to relieve inflammation, reduce pain, and prevent the disease from worsening. This surgery is an effective treatment method, but the surgery and postoperative care must strictly follow the doctor's instructions to ensure the best results. During this surgical procedure, a special drainage device is needed to complete the drainage process.

[0003] The drainage device used in breast surgery in the prior art directly extracts the pathological fluid in the breast into the interior of the drainage bag under negative pressure through a drainage needle and a drainage tube.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 7 The present invention provides the following technical solutions: a novel drainage device for breast surgery, comprising a drainage device body, the drainage device body comprising a drainage tube 2, a drainage bag 3, a suction mechanism 5 and an adjustment component 6, one end of the drainage tube 2 is sleeved with a drainage needle 1, the other end of the drainage tube 2 is sleeved with a drainage bag 3, both sides of the drainage bag 3 are respectively installed with a flip plate 28 and a fixed plate 29, the drainage bag 3 is used to accumulate the pathological fluid drawn in by drainage, one end of the top of the drainage bag 3 is inserted with a suction pipe 4, the end of the suction pipe 4 A hollow plate 7 is installed at the end, and a plurality of suction mechanisms 5 are installed on the surface of the hollow plate 7. Each suction mechanism 5 is provided with an independent top plate 14. An extension plate 17 is integrally formed on the side of the hollow plate 7. A through hole 18 is provided inside the extension plate 17. An adjustment component 6 is inserted inside the through hole 18, and each top plate 14 passes through the inside of the through hole 18. The side of the adjustment component 6 is pressed and fitted with one side of the top plate 14. The inside of the hollow plate 7 is connected to the internal cavity of the drainage bag 3 through the suction pipe 4. The new breast surgery drainage device is used in breast surgery drainage operations to draw pathological solutions at the drainage site into the inside of the drainage bag 3.

[0021] When the present invention is used, during a breast surgical drainage operation, the drainage needle 1 is manually controlled to be embedded into the breast skin area that needs drainage, and then the pathological solution is directly discharged outward with the help of the intrathoracic pressure and enters the interior of the drainage bag 3. Subsequently, the doctor manually controls the suction mechanism 5 to extract, ensuring that all the remaining liquid can eventually enter the interior of the drainage bag 3 along the drainage tube 2. In this process, the adjustment component 6 is manually controlled to rotate to control the damping effect of each suction mechanism 5 during suction, thereby coordinating the suction process to control the accuracy of extraction.

[0022] In this embodiment, the air extraction pipeline 4 includes a shunt pipeline 9 and a collection pipeline 10. The number of the shunt pipelines 9 and the suction mechanism 5 is the same, and one end of each shunt pipeline 9 is independently connected to the internal cavity of the hollow plate 7, and the middle of the collection pipeline 10 is connected with a plug pipeline 11. The other end of the shunt pipeline 9 is connected to the inside of the collection pipeline 10, and the shunt pipeline 9 is staggered with the extension plate 17. A pressing groove 8 is provided on one side of the hollow plate 7, and the pressing groove 8 is used to provide a pressing area for the thumb to apply force.

[0023] Specifically, by manually pressing the suction mechanism 5, a negative pressure state can be formed inside the hollow plate 7, thereby causing a negative pressure state to be formed inside the entire exhaust pipe 4. At this time, the pathological fluid in the patient's body can be extracted from the drainage tube 2 and the drainage needle 1, and finally enter the middle drainage bag 3 for collection, while the gas part will be drawn into the interior of the hollow plate 7, causing the air bag in each suction mechanism 5 to expand.

[0024] In this embodiment, the suction mechanism 5 includes a compressed air bag 12 and a top plate 14. One end of the compressed air bag 12 is embedded in the hollow plate 7. The other end of the compressed air bag 12 is mounted with a linkage plate 13. The end of the top plate 14 is welded to the inner side of the linkage plate 13. One side of the top plate 14 is integrally formed with a plurality of convex strips 16. A pressing plate 15 is integrally formed at the end of the top plate 14. The height of the top plate 14 is the same as the height of the through hole 18. There are four suction mechanisms 5, and the top plates 14 in each suction mechanism 5 are kept in a parallel state. By connecting the suction mechanism 5 to the drainage bag 3 part using a pipe, the suction rate can be manually controlled, and multiple suction mechanisms 5 are used in combination, and the number of suction mechanisms 5 used to provide suction effect during drainage can be controlled by one hand, thereby flexibly controlling the strength and rate of suction provided.

[0025] Specifically, when performing suction, the thumb is pressed against the inside of the groove 8, and the remaining four fingers are pressed on each pressing plate 15. By controlling each pressing plate 15 to push it one by one, the compressed air bag 12 can be finally controlled to expand with the help of the top plate 14 and the linkage plate 13, so that a negative pressure state is generated inside the hollow plate 7. In this process, a single suction mechanism 5 can be controlled to perform suction processing or multiple suction mechanisms 5 can be controlled to perform suction processing at the same time.

[0026] In this embodiment, the adjustment assembly 6 includes an adjustment knob 24 and an extrusion wheel 22. The bottom of the adjustment knob 24 is integrally formed with a threaded column 20. The surface of the threaded column 20 is provided with an extrusion convex ring 21. The extrusion wheel 22 is sleeved on the bottom of the threaded column 20, and a rubber ring 23 is attached to the side of the extrusion wheel 22. The extrusion wheel 22 is extruded on the side of the top plate 14 through the rubber ring 23 on the side. The extrusion convex ring 21 is pressed against the top of the extrusion wheel 22. The threaded column 20 is inserted downward into the through hole 18 from the top of the extension plate 17. A clamping rod 25 is also inserted into the interior of the extension plate 17. The top of the clamping rod 25 is integrally formed with a protrusion 19. The clamping rod 25 is pressed against the surface of the protrusion 16, and the clamping rod 25 can be pulled out from the surface through the protrusion 19 on the top. The cross-sections of the clamping rod 25 and the protrusion 16 are both triangular structures, and the extrusion wheel 22 cooperates with the clamping rod 25 to clamp part of the top plate 14. An independent adjustment component 6 is installed in each suction mechanism 5. Therefore, the suction mechanism 5 and the adjustment component 6 can also adjust the damping generated during auxiliary suction, so that the rate of each suction mechanism 5 during air suction and drainage can be adjusted, and the accuracy of suction can also be improved.

[0027] Specifically, when the top plate 14 is controlled to pass through the inside of the through hole 18, the clamping rod 25 will be pressed against the convex strip 16 of the helical tooth structure, so that the top plate 14 can only be pulled in one direction, and will not move in the opposite direction. Therefore, this structure can avoid the compression airbag 12 from shrinking due to external collision, thereby causing the liquid extracted from the drainage tube 2 to reflux. After the suction is completed, the entire drainage device is taken out and the suction mechanism 5 is disassembled, the entire clamping rod 25 can be directly pulled out from the top of the extension plate 17 by pulling the convex block 19. At this time, the pressing plate 15 can be manually pulled to reset the compression airbag 12 to the compressed state. At the same time, the downward pressure provided by the extrusion convex ring 21 to the top of the extrusion wheel 22 can be controlled by turning the adjusting knob 24, thereby changing the resistance of the extrusion wheel 22 when it rotates. Therefore, when the top plate 14 is pressed, the pressure required to press the top plate 14 can be controlled by turning the adjusting knob 24, so that the pushing speed control of the top plate 14 is more accurate and reliable.

[0028] In this embodiment, the drainage bag 3 includes an extraction sleeve 26 and a fluid storage bag 30, the drainage tube 2 is embedded in the surface of the extraction sleeve 26, one end of the extraction sleeve 26 is integrally formed with a docking sleeve 27, the plug-in pipe 11 is embedded in the interior of the docking sleeve 27, the flip plate 28 and the fixed plate 29 are respectively attached to the two sides of the fluid storage bag 30, and a second magnetic sheet 32 ​​is attached to one side of the flip plate 28, and a first magnetic sheet 31 is embedded on one side of the fixed plate 29. The second magnetic sheet 32 ​​is an arc-shaped structure as a whole, and sealing strips 33 are embedded on the inner walls of the fixed plate 29 and the flip plate 28, and a docking groove 34 is opened on one side of each sealing strip 33, and the sealing strip 33 is embedded in the corresponding docking groove 34 after rotating from the flip plate 28 toward the fixed plate 29. A flip plate 28 and a fixed plate 29 are arranged on both sides of the drainage bag 3, and a magnetic attraction structure is arranged at the bottom of the drainage bag 3, which cooperates with the one-way locking structure in the suction mechanism 5 to prevent liquid backflow and prevent the liquid inside the drainage bag 3 from entering the extraction structure at the rear end during the suction process, thereby ensuring that the suction mechanism 5 can be reused.

[0029] Specifically, after the liquid inside the drainage tube 2 is drawn into the interior of the suction sleeve by suction, it will directly fall into the liquid storage capsule 30 at the bottom of the drainage bag 3 at the bottom. At this time, the accumulation of liquid can make the flip plate 28 and the fixed plate 29 move, which will cause the position of the first magnetic sheet 31 and the second magnetic sheet 32 ​​to change. As the suction mechanism 5 proceeds, since both the flip plate 28 and the fixed plate 29 are made of rigid materials and the distance between the two is affected by the bottom magnetic structure, it is difficult to cause the liquid storage capsule 30 to shrink only by the suction of airflow. Therefore, it can prevent the suction mechanism 5 from causing the liquid storage capsule 30 to shrink during the subsequent suction process and causing part of the liquid to enter the suction pipe 4 or even the suction mechanism 5, so as to ensure that the suction mechanism 5 and the suction pipe 4 will not be seriously contaminated, and facilitate reuse after subsequent disinfection.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
