Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an adjustable-angle multi-channel intraoperative drainage tube bundle fixation device. Background Technology

[0002] Drainage tube bundle fixation devices are primarily used in surgical procedures involving the simultaneous placement of multiple drainage tubes. The core components consist of a fixation base, a multi-channel limiting structure, and a locking assembly. The fixation base conforms to the patient's skin, the limiting structure gathers multiple drainage tubes to prevent tangling, and the locking assembly secures the tubes, preventing displacement or unplanned removal. These devices often employ an integrated fixation structure, aiming to simplify intraoperative tube management and improve the convenience of multi-tube fixation. They are suitable for postoperative drainage support in complex surgeries such as abdominal and thoracic surgeries and are commonly used instruments in surgical intraoperative and postoperative care.

[0003] Existing drainage tube bundle fixation devices have significant technical defects, making them difficult to adapt to the dynamic needs of surgery. Firstly, they lack or have insufficient angle adjustment capabilities. The connection between the fixation base and the tube is mostly rigid, making it impossible to flexibly adjust the drainage tube angle according to changes in surgical position or the placement of the drainage bag. This results in the tube routing not matching the actual needs, easily leading to bending, compression, increased drainage resistance, and even drainage interruption. Secondly, they lack anti-torsion structures during angle adjustment. Even when attempting simple angle adjustments, the direct rigid connection between the tube and the fixation base easily generates torsional stress during adjustment, causing the drainage tube to twist and deform, disrupting the patency of the lumen, and exacerbating traction damage at the puncture site. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable-angle multi-channel intraoperative drainage tube bundle fixation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] Adjustable angle multi-channel intraoperative drainage tube bundle fixation device, including

[0007] The mounting base has at least one mounting groove on its surface;

[0008] At least one docking platform is installed in the mounting slot, the docking platform including a guide plate and a connecting seat connected to each other, the guide plate being rotatable and tiltable;

[0009] The positioning unit has two states: locked and unlocked. When the positioning unit is in the locked state, it is used to fix the guide plate so that it cannot rotate. When the positioning unit is in the unlocked state, the guide plate can rotate.

[0010] The connecting pipe is installed inside the guide plate. The connecting pipe has a first port and a second port and is used to connect two drainage tubes to form a drainage channel. The second port is movably adapted to the drainage tube.

[0011] The docking unit is installed on the inner wall of the docking pipe port to seal the connection between the drainage pipe and the docking pipe, thus preventing leakage of the drainage channel.

[0012] Preferably, the connecting seat has a fixing groove, a rotating shaft is movably connected in the inner cavity of the fixing groove, a blade is fixedly connected to the outer side of the rotating shaft, a steering groove is provided on the side of the guide plate connected to the connecting seat, a steering ring is movably connected in the inner cavity of the steering groove, and the steering ring is fixedly connected to the blade.

[0013] Preferably, the guide plate has a turning channel, which is L-shaped and runs through two non-parallel side walls of the guide plate. The connecting pipe is located in the inner cavity of the turning channel and turns the drainage channel by connecting two drainage pipes. The connecting seat has a docking channel, and the drainage pipe connected to the second port passes through the docking channel to connect with the human body.

[0014] Preferably, a connecting shaft is also provided on the outside of the docking channel in the connecting seat. The positioning unit is connected to the guide plate through the connecting shaft. A brake ring is fixedly connected to the outside of one end of the connecting shaft. When the positioning unit is in the locked state, the brake ring is fixed so that the connecting shaft cannot rotate. When the positioning unit is in the unlocked state, the brake ring is not fixed.

[0015] Preferably, the positioning unit includes two positioning plates and a transmission block. A brake plate is fixedly connected to the inner side of each of the two positioning plates. The two transmission blocks are fixedly connected to the two positioning plates respectively. A transmission bar is connected between the two transmission blocks. The connection surface between the transmission block and the transmission bar is set as a mutually compatible inclined surface.

[0016] Preferably, the docking unit includes a fixing ring, the inner side of which has at least two arc-shaped grooves, a locking ring is installed in the inner cavity of the arc-shaped grooves, the side of the locking ring facing the steering channel port is set as an inclined surface, the inner cavity of the arc-shaped grooves is also provided with a second spring for providing continuous thrust to the locking ring, and a sealing ring is fixedly connected to the inner side of the locking ring.

[0017] Preferably, an airbag is also provided in the inner cavity of the arc-shaped groove, and an air supply pipe is fixedly connected to one side of the airbag, so that the inner cavity of the airbag and the inner cavity of the sealing ring are interconnected through the air supply pipe.

[0018] Preferably, the air supply pipe has a sealed channel and an air guide channel that are interconnected. The inner diameter of the sealed channel is smaller than that of the air guide channel, and a sealing plate is provided in the inner cavity of the sealed channel. The sealing plate is connected to the inner cavity of the sealed channel by a torsion spring.

[0019] Preferably, the inclined surface of the transmission block is provided with a sliding groove, and the inclined surface of the transmission bar has a slider that matches the sliding groove, so that the transmission bar can move along the inclined surface of the transmission block.

[0020] Preferably, the connecting pipe has a flexible section, which can deform as the guide plate tilts, adapting to angle adjustments and ensuring unobstructed drainage channels.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In this invention, a deflector tube is set inside the fixed base, with the two ends of the deflector tube respectively connected to the first drainage tube and the second drainage tube. When the patient's position changes during surgery or the position of the drainage bag is adjusted, the deflector tube can rotate and tilt flexibly, causing the first drainage tube to adjust its angle synchronously to adapt to the actual needs. This ensures that the drainage tube always maintains a smooth flow, avoids bending and twisting, and achieves a stable drainage effect. This solves the technical problems of increased drainage resistance, drainage interruption, and traction damage at the puncture point caused by angle adjustment in existing devices.

[0023] 2. In addition, the first drainage tube is fixed by the positioning unit. Before the angle is adjusted, the button needs to be pressed to release the positioning unit from fixing the first drainage tube. During the adjustment process, the positioning unit is in the unlocked state, which makes it easy for the deflector to drive the drainage tube to adjust the angle flexibly. After the adjustment is completed, the button is released, the positioning unit automatically resets and refixes the drainage tube, avoiding the problem that the drainage tube is easily moved by external force and the position is offset. This ensures the flexibility of the angle adjustment and improves the stability after the angle is fixed.

[0024] 3. Based on the above structure, by setting sealing units at both ends of the deflector, when the first and second drainage pipes are connected to the deflector, the sealing units fit into the pipe interface to form a closed-loop sealing structure, which solves the problem of leakage and backflow infection caused by gaps at the interface during the rotation and tilting of the deflector. While ensuring flexible angle adjustment and stable locking, the sealing reliability of the pipe connection is enhanced. Attached Figure Description

Detailed Implementation

[0037] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figures 1-3 The embodiment shown discloses an adjustable angle multi-channel intraoperative drainage tube bundle fixing device, including a fixing base 100, a docking platform 200, a positioning unit 300, and a connecting tube 400. The fixing base 100 is attached to the surface of human skin and is in contact with the part of the body that needs drainage during use. The fixing base 100 has two mounting slots, and the docking platform 200 is installed in the mounting slots. The docking platform 200 includes a guide plate 210, and a turning channel 211 is provided on the guide plate 210. The connecting tube 400 is installed in the turning channel 211.

[0040] like Figures 2-3 As shown, a connecting seat 220 is movably connected to the bottom of the guide plate 210, and the guide plate 210 can rotate and tilt along the top of the connecting seat 220. A turning channel 211 is provided on the guide plate 210, and the turning channel 211 is L-shaped and runs through the side and bottom of the guide plate 210. A connecting pipe 400 is provided in the turning channel 211. The connecting pipe 400 has a first port and a second port. The first port faces the side of the guide plate 210, and the second port faces the bottom of the guide plate 210. A drainage tube can be connected to the side and bottom of the guide plate 210 respectively through the connecting pipe 400. The two drainage tubes realize a turning drainage channel through the connecting pipe 400. When the guide plate 210 is in a rotatable state, the position of the hose connected to the side of the guide plate 210 can be adjusted by rotating the guide plate 210, thereby adjusting the angle of the drainage tube in the horizontal direction, while the hose connected to the bottom of the guide plate 210 remains fixed and connected to the human body drainage part.

[0041] like Figure 2 and Figure 4 As shown, a connecting shaft 230 is fixedly connected to the bottom of the guide plate 210, so that the guide plate 210 drives the connecting shaft 230 to rotate during the rotation. The positioning unit 300 has two states: locked and unlocked. When the positioning unit 300 is in the locked state, the brake plate 320 clamps the brake ring 231, and the connecting shaft 230 cannot rotate, thereby fixing the guide plate 210 and preventing it from rotating unexpectedly under the influence of external force. This would result in the drainage tube not being fixed in the horizontal direction, which could easily lead to displacement, infection, and drainage interruption. When the positioning unit 300 is in the unlocked state, the angle of the drainage tube in the horizontal direction can be adjusted. The surface of the connecting seat 220 is provided with a docking channel 240, and the drainage tube connected to the second port of the docking tube 400 can pass through the docking channel 240 to connect with the human body drainage site.

[0042] like Figures 5-6As shown, the top of the connecting seat 220 has a fixing groove 221. A rotating shaft 222 is movably connected to the inner cavity of the fixing groove 221. A blade 223 is fixedly connected to the outer side of the rotating shaft 222. The lower surface of the guide plate 210 has a turning groove 212. A turning ring 213 is movably connected to the inner cavity of the turning groove 212. The blade 223 is fixedly connected to the turning ring 213, ensuring that the position of the turning ring 213 remains unchanged when the guide plate 210 rotates due to its connection with the blade 223. This prevents the connecting seat 220 from rotating when the guide plate 210 rotates. Simultaneously, when adjusting the vertical angle of the guide plate 210, this adjustment should be performed before horizontal adjustment, and the vertical adjustment angle should not exceed 15°. Within this range, a gap remains between the blade 223 and the fixing groove 221 to prevent interference. After vertical adjustment, the angle is maintained by the friction between the rotating shaft 222 and the fixing groove 221 before horizontal adjustment. By rotating the shaft 222 within the cavity of the fixed groove 221, the guide plate 210 can be adjusted vertically, allowing the drainage pipe connected to the side of the guide plate 210 to be adjusted horizontally and vertically simultaneously. In other words, the vertical tilting function of the guide plate 210 primarily assists in fine-tuning the flexible section 410 of the connecting pipe 400. After horizontal rotation adjustment, the drainage pipe connected to the first port can have its routing further optimized by a small tilt of the guide plate 210, reducing bending stress on the flexible section 410. The vertical angle does not need to be independently locked; the position is maintained by the damping action between the shaft 222 and the fixed groove 221.

[0043] like Figure 8 As shown, the connecting pipe 400 has a flexible section 410, which is made of rubber and can adapt to the vertical angle adjustment of the first port of the connecting pipe 400, so that the first port changes angle and the vertical angle of the drainage tube can be adjusted.

[0044] In order to make the guide plate 210 rotatable, such as Figure 7As shown, specifically, a brake ring 231 is provided on the bottom outer edge of the connecting shaft 230. The positioning unit 300 includes two positioning plates 310, each with a brake plate 320 fixedly connected to its inner side. A transmission block 330 is connected to each positioning plate 310, and a transmission bar 340 is connected between the two transmission blocks 330. The connection surfaces of the transmission blocks 330 and the transmission bar 340 are set as mutually adaptable inclined surfaces, and a sliding groove is provided on the transmission block 330. A slider is provided on the transmission bar 340, allowing the transmission bar 340 to move along the inclined surface of the transmission block 330. The transmission bar 340 is controlled... As the device moves toward the positioning plate 310, the distance between the inclined surfaces of the two transmission blocks 330 gradually decreases in this direction. This causes the transmission bar 340 to exert a lateral force on the two transmission blocks 330 during movement, increasing the distance between them. Since the transmission blocks 330 are fixedly connected to the positioning plate 310, the two positioning plates 310 move synchronously, increasing the distance between them. This causes the two brake plates 320 to disengage from the outside of the brake ring 231, releasing the rotational restriction on the brake ring 231. This allows the connecting shaft 230 to rotate normally, and the guide plate 210 can rotate to adjust the horizontal angle of the drainage tube. Figure 2 As shown, a button is provided on one side of the fixed base 100. The button is connected to the transmission bar 340. That is, by pressing the button, the positioning unit 300 can be in the unlocked state and the guide plate 210 can be in the rotatable state.

[0045] To keep the guide plate 210 in a non-rotatable state, continue as follows Figure 7 As shown, specifically, the positioning plate 310 has a first spring 350 connected to both sides. The first spring 350 is internally connected to the fixed base 100. When the positioning plates 310 separate, they compress the first spring 350, providing a continuous pushing force. When the button stops pushing the transmission bar 340, the first spring 350 gradually pushes the two positioning plates 310 closer together, causing the brake plate 320 to return to the outside of the brake ring 231, preventing the brake ring 231 from rotating. At the same time, the two transmission blocks 330 move closer together and push the transmission bar 340 back to its original position for easy unlocking next time. When the rotation of the brake ring 231 is prevented, the linkage shaft 230 cannot rotate, making the guide plate 210 non-rotatable. A guide hole is opened on the side of the fixed base 100, and the button is installed in the guide hole. The rear end of the button is directly fixedly connected to the transmission bar 340. A reset spring is provided between the button and the inner wall of the fixed base to assist the first spring 350 in completing the reset.

[0046] It should be noted that the first spring 350 remains compressed in the locked state, applying a continuous preload to the positioning plate 310. This maintains a static friction force between the brake plate 320 and the brake ring 231, ensuring their stability. This static friction force is sufficient to resist external disturbances such as routine handling and changes in patient positioning, ensuring a stable locked state. When angle adjustment is required, the button must be actively pressed to overcome the preload force and unlock the device.

[0047] In order to enable the connector 400 to connect to the drainage tube, such as Figures 8-9 As shown, specifically, a docking unit 500 is provided at each end of the inner cavity of the connecting pipe 400. The docking unit 500 includes a fixing ring 510 and a locking ring 520. Two arc-shaped grooves 511 are formed on the inner side of the fixing ring 510. The locking ring 520 is installed in the inner cavity of the arc-shaped grooves 511, and a second spring 521 is provided in the inner cavity of the arc-shaped grooves 511. The second spring 521 continuously provides a thrust to the locking ring 520. The side of the locking ring 520 facing the port of the connecting pipe 400 is... When the drainage tube enters the port of the connecting tube 400, it contacts the inclined surface of the locking ring 520 and pushes the two locking rings 520 into the depth of the arc groove 511, so that the second spring 521 is compressed. The second spring 521 continuously applies a pushing force to the locking ring 520, so that the locking ring 520 moves to the outside of the drainage tube. The drainage tube is clamped and fixed by the two locking rings 520, so that the drainage tube is fixed at the port of the connecting tube 400, and the drainage tube and the connecting tube 400 are connected.

[0048] It was also found during use that when the connector 400 is connected to the drainage pipe, a gap may easily appear at the connection between the drainage pipe and the connector 400, causing the drainage material to leak from the connection between the connector 400 and the drainage pipe, which can easily lead to liquid accumulation and pipeline contamination.

[0049] To address the aforementioned issues, the improved solution includes, for example... Figure 10 As shown, specifically, an airbag 522 is also provided in the inner cavity of the arc-shaped groove 511. The airbag 522 has a hollow chamber containing air. When the drainage tube is connected to the port of the connecting tube 400, the locking ring 520 moves deeper into the arc-shaped groove 511, causing the locking ring 520 to compress the airbag 522, increasing the pressure in the hollow chamber of the airbag 522. An air supply tube 540 is provided on one side of the airbag 522, and a sealing ring 530 is provided on the outer side of the locking ring 520. The hollow chamber of the airbag 522 is connected to the inner chamber of the sealing ring 530 through the air supply tube 540, so that the air in the airbag 522 enters the sealing ring 530 under pressure, causing it to inflate and fit against the outer wall of the drainage tube. The sealing ring 530 is located inside the locking ring 520 and contacts the drainage tube. When the sealing ring 530 expands, it fills the gap between the locking ring 520 and the drainage tube, enhancing the sealing performance at the connection between the drainage tube and the connecting tube 400.

[0050] In a more preferred embodiment, such as Figure 11 As shown, specifically, the air supply tube 540 has a sealing channel 541 and an air guiding channel 542. The sealing channel 541 communicates with the hollow chamber of the airbag 522, and the air guiding channel 542 communicates with the inner cavity of the sealing ring 530. The inner diameter of the sealing channel 541 is smaller than the inner diameter of the air guiding channel 542. A sealing plate 543 is installed in the inner wall of the sealing channel 541, and a torsion spring 544 is connected to the outer side of the sealing plate 543. The sealing channel 541 is connected to the sealing plate 543 through the torsion spring 544. When pressure is generated in the hollow chamber of the airbag 522, the sealing plate 543 is pushed into the air guiding channel 542 under the pressure. The sealing plate 543 and the air guiding channel 542 are connected. A gap exists between the gas guide channel 542 and the sealing plate 543, allowing gas to replenish the inner cavity of the sealing ring 530. This causes the sealing ring 530 to expand, and the gas in the airbag 522 is discharged. The pressure in the cavity returns to normal. At this time, the sealing plate 543 is not affected by the thrust. However, when it moves, the torsion spring 544 deforms, and the torsion spring 544 exerts a pulling force on the sealing plate 543, causing the sealing plate 543 to enter the sealing channel 541 from the inner cavity of the gas guide channel 542. This prevents gas from passing through the gas replenishment pipe 540, thus effectively preventing air in the sealing ring 530 from flowing back into the airbag 522 and maintaining the sealing effect of the sealing ring 530.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. The present invention is not limited to the above embodiments; the embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
