Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a pericardial effusion puncture and drainage device with angle adjustment. Background Technology

[0002] Pericardial effusion refers to the abnormal accumulation of fluid within the pericardial cavity. Normally, only a small amount of fluid serves a lubricating function in the pericardial cavity, but a volume exceeding 50 ml is sufficient for diagnosis. In clinical practice, pericardiothoracic puncture and drainage are key treatment methods for patients with pericardial and pleural effusions. Timely and effective drainage of this fluid can significantly alleviate symptoms such as dyspnea and palpitations caused by fluid compression of the heart and lungs, providing strong support for diagnosis and subsequent treatment.

[0003] In response to this, invention patent CN118680643B discloses a pericardial thoracentesis and effusion drainage device and method, belonging to the field of medical puncture equipment technology. The device includes a puncture mechanism and an effusion drainage mechanism. The effusion drainage mechanism includes a sealing disc with an inlet tube and an outlet tube passing through it. The inlet tube is fluidly coupled to the puncture mechanism via a flexible tube, and the outlet tube is coupled to an external effusion storage container. A cylinder is rotatably coupled to the sealing disc and has a first chamber and a second chamber. The device is adapted to alternately extract and drain effusion from the first chamber and the second chamber via the inlet tube and the outlet tube through the relative rotation of the sealing disc and the cylinder. In this way, uninterrupted drainage can be achieved through the pericardial thoracentesis and effusion drainage device.

[0004] However, the pericardiothoracentesis device in the aforementioned patent still has some problems: when performing pericardiothoracentesis, doctors need to adjust the puncture angle, but after working for a long time, doctors' hands become tired, making it difficult to stably adjust and calibrate the angle. At the same time, the puncture point cannot be pre-calibrated, which leads to inconvenience for personnel and reduces work efficiency. Furthermore, after puncture and drainage, some patients, such as the elderly and children, have poor self-control and are prone to damaging the placed drainage device, affecting subsequent treatment.

[0017] Compared with the prior art, the present invention provides a pericardial effusion puncture and drainage device with angle adjustment, which has the following beneficial effects:

[0018] 1. This pericardial effusion puncture and drainage device with angle adjustment works in conjunction with the puncture mechanism through a support mechanism on the mounting mechanism. The first worm gear in the first adjustment box drives the first worm wheel, and the second worm gear drives the second worm wheel, which in turn drives the large gear through the small gear.

The movable elongated hole of the crossbar is inserted and connected to the limiting pin. The movable support plate on the movable block is connected to a movable column. When adjusting the puncture angle, the doctor can push the puncture needle. At this time, the rubber sleeve contacts the patient's body, and the doctor can then check the puncture point, which is convenient for its use.

[0020] 3. This pericardial effusion puncture and drainage device with angle adjustment, through the cooperation of the installation mechanism and the support mechanism, allows the installation mechanism to be installed on the operating table after the patient lies down before puncture. By turning the first crank, the adjustment screw can be driven, which can clamp and fix the two side frames on the operating table. In the support mechanism, the sliding rod and the through hole of the movable cross block are interlocked and connected, and then adjusted in conjunction with the installation mechanism to ensure the overall stability of the device and ensure the subsequent puncture operation.

[0021] 4. This pericardial effusion puncture and drainage device with adjustable angle, through the cooperation of the installation mechanism and the isolation mechanism, allows the isolation plate to be installed after the puncture operation to prevent the patient from observing or touching the puncture site, avoid affecting the patient's emotions, prevent the patient from touching the affected area, and promote the patient's recovery in the early stage of the operation.

[0022] 5. This pericardial effusion puncture and drainage device with adjustable angle features an installation mechanism that works in conjunction with a support mechanism. The puncture mechanism on the support mechanism is connected to a drainage tube guide mechanism. After puncture, the crossbar and its components can be removed. The drainage tube guide mechanism can be used to fix and adjust the drainage tube according to its orientation, ensuring that the drainage tube is stably fixed close to the patient's wound. The position of the support frame can be adjusted to position the clamping assembly appropriately for the patient. The drainage tube guide mechanism on the puncture mechanism works in conjunction with the drainage mechanism and the clamping assembly. When the drainage device is in place, it can limit and fix the drainage tube at multiple points. At the same time, the fixing position of the drainage bag can be flexibly adjusted to ensure a reasonable layout of the drainage device, preventing the drainage device from being pulled on the patient's wound by external forces, and improving the safety of patient use.

This allows the two side frames 101 to be clamped on both sides of the operating table. In the support mechanism 2, when the other side frame 101 is in place, the slide rod 207 is threadedly connected to one of the movable horizontal blocks 206, and the slide rod 207 is inserted into the through hole of the other movable horizontal block 206, allowing one support frame 201 to move closer to the other support frame 201.

[0050] When the operator loosens the positioning knob 204, the support frame 201 can be pulled, causing the connected movable ring 202 to move on the threaded column 103, thereby changing the position of the support mechanism 2. When the operator rotates the second crank 209, the lead screw 205 drives the movable cross block 206, thereby changing the height of the slide bar 207 on it, and thus changing the height of the piercing mechanism 5 on the slide bar 207. At the same time, when the operator loosens the pressing knob 504, the moving part 501 can change its position on the slide bar 207.

[0051] After the position of the puncture mechanism 5 is adjusted, the doctor can confirm the puncture angle and puncture point according to the patient's condition. Rotating the first turntable causes the first worm gear 524 to drive the first worm wheel 523, which in turn rotates the second adjustment box 506. Then, rotating the second turntable causes the second worm gear 525 to drive the second worm wheel 526, which in turn drives the large gear 528 via the small gear 527. The large gear 528 then drives the connecting sleeve 532 on the connecting stud 531, thereby finely adjusting the angle of the crossbar 507. After adjustment, the doctor can push the puncture syringe 511. At this time, the rubber sleeve 522 on the puncture needle 513 is still in contact with the patient, allowing the doctor to determine the puncture point. During puncture, the doctor pulls the crossbar 521. 521 drives the moving block 519 through the limiting pin 520, and the movable support plate 518 drives the movable column 515 to move. With the cooperation of the fixed support plate 514 and the baffle 516, the first return spring 517 is compressed. When the crossbar 521 is pulled, the rubber sleeve 522 separates from the puncture needle 513. At the same time, the crossbar 521 is moved, and the rubber sleeve 522 can be removed for disinfection. At this time, the personnel can push the puncture syringe 511. The T-shaped slider 509 connected to the first opening ring 510 slides along the guide rod 529. A fixed spring 530 is connected between the two T-shaped sliders 509 to ensure the stable movement of the puncture syringe 511 on the two first opening rings 510. The puncture needle 513 on the puncture syringe 511 moves, and the puncture operation can be performed.

[0052] After puncture, the puncture mechanism 5 can move on the support mechanism 2, and the support mechanism 2 can move on the installation mechanism 1, changing the position between the catheter guide mechanism 7, the clamping assembly 6, and the drainage mechanism 3 on the puncture mechanism 5. After puncture, the doctor uses the indwelling catheter and the puncture needle 511 for placement. After the indwelling catheter is connected to the drainage tube, the staff adjusts the catheter guide mechanism 7 according to the orientation of the indwelling catheter and the drainage tube. Similarly, the puncture mechanism 5 is used to adjust the catheter guide mechanism 7 to a suitable angle. Then, the staff pulls the baffle 708 through the pull ring 709, thereby moving the connecting column 705 upward, compressing the second reset spring 707, and connecting... Plate 706 moves the toothed block 710 upward to release the restriction on the rotating gear 711. At this time, the second guide plate 703 can be rotated to form a suitable angle with the first guide plate 701. The pull ring 709 is released, and under the action of the second return spring 707, the toothed block 710 is reset to limit the rotating gear 711. With the drainage tube close to the infusion tube, the indwelling tube and the drainage tube can be placed in the second opening ring 713 respectively. Pulling the lever 716 compresses the clamping spring 717. At this time, the moving column 714 moves the arc-shaped pressure plate 715. After the indwelling tube and the drainage tube are placed in the second opening ring 713, releasing the lever 716 will compress the clamping spring 717. The indwelling tube and drainage tube are fixed under elastic force. Sufficient tube length can be left between the two second open rings 713 to avoid straightening and form an effective buffer length. Then, the middle part of the drainage tube is limited and fixed by the tube clamping assembly 6 on one side. Pressing down on the movable clamp 602 compresses the connecting spring 604 between the movable clamp 602 and the fixed plate 603. The drainage tube is placed between the movable clamp 602 and the fixed clamp 601. Under the elastic force of the connecting spring 604, the drainage tube is limited and fixed. Then, the corresponding drainage mechanism 3 is selected. The connecting ring 303 can move on the connecting rod 302, thereby changing the position of the side plate 304. After adjusting the position of the side plate 304, the drainage bag 306 can be placed in a suitable position. The side plate 304 is connected to a protective cover 305, which can protect the drainage bag 306. The drainage tube is threaded through the tube protection hose 307, and then the drainage tube is connected to the drainage bag 306. The indwelling tube and the drainage tube are stably fixed in the orientation position by the drainage tube guide mechanism. Then, the middle part of the drainage tube is limited by the tube clamp assembly 6 to ensure the stable fixation of the drainage tube. The path of the drainage tube connected to the indwelling tube from the drainage tube guide mechanism 7 to the tube clamp assembly 6 and then to the drainage mechanism 3 forms a reasonable distribution, ensuring a reasonable layout of the drainage device and reducing the impact on the patient.

[0053] After the puncture procedure, the staff aligns the support column connected to the isolation plate 403 with the support sleeve 402 connected to the support ring 401 to isolate the puncture site, preventing the patient from observing or touching the puncture site, avoiding any impact on the patient's emotions, preventing the patient from touching the affected area, and promoting the patient's recovery in the early stages of the procedure. At the same time, the medical staff can quickly remove the isolation plate 403 to facilitate subsequent treatment of the patient.
