Abstract
Description
Technical Field
[0001] This utility model relates to the field of devices for treating hematoma after VABB surgery, and in particular to a device for treating hematoma after VABB surgery. Background Technology
[0002] Breast lumps are a common and prevalent disease among women. For lumps that pose a risk or are large, surgical treatment is often required. Vacuum-assisted breast lump excision (VABB) is favored by the public due to its many advantages and is often the first choice for surgical treatment.
[0003] However, due to the minimally invasive nature of VABB surgery, intraoperative hemostasis cannot be achieved through methods such as electrocoagulation and ligation as in traditional surgery. Postoperatively, hemostasis is typically achieved by wrapping the area with gauze and padding bandages for pressure. For patients who have undergone multifocal resection, the effect of bandage fixation and pressure is even less certain, often leading to postoperative hematoma. Furthermore, patients with active physical activity on the affected side, or those with underlying conditions such as hypertension or diabetes, have a significantly increased risk of postoperative hematoma. Larger hematomas often cause swelling and pain, requiring puncture and drainage. Traditional open drainage creates excessively large incisions, contradicting the small incision principle of VABB surgery. Repeated aspiration with a syringe needle prolongs the procedure and can result in incomplete hematoma flushing. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies and provide a device for treating hematoma after VABB surgery, including a cutting and puncture circulating irrigation device. The cutting and puncture circulating irrigation device includes: a needle tube with a needle tip disposed below it; a first irrigation tube connected to one side of the needle tube; and a second irrigation tube connected to the other side of the needle tube. The needle tube, the first irrigation tube, and the second irrigation tube are integrally formed. A suction tube is connected to the top of the needle tube. A first water injection tube is connected to one side of the first irrigation tube, and a second water injection tube is connected to one side of the second irrigation tube.
[0005] As a further description of the above technical solution: a first liquid inlet is provided below the first flushing pipe, and a second liquid inlet is provided below the second flushing pipe.
[0006] As a further description of the above technical solution: the needle tube is connected between the first flushing tube and the second flushing tube, and the suction tube is located between the first water injection tube and the second water injection tube.
[0007] As a further description of the above technical solution: the needle tube has multiple suction holes on its side.
[0008] As a further description of the above technical solution: an adsorption port is formed at the lower end of the needle.
[0009] As a further description of the above technical solution: the needle tube is in the shape of a thin sheet.
[0010] As a further description of the above technical solution: the length of the needle tube is 5mm.
[0011] The VABB postoperative hematoma treatment device provided by this utility model also includes a VABB postoperative drainage component. The VABB postoperative drainage component includes a drainage tube, and a water inlet pipe is provided inside the drainage tube. The water inlet pipe is connected to a water injection valve through a water inlet, and one end of the drainage tube is connected to a drainage bag.
[0012] As a further description of the above technical solution: drainage grooves are provided on both sides of the bottom of the drainage tube.
[0013] As a further description of the above technical solution: the drainage tube is thin and elliptical.
[0014] The above technical solution has the following advantages or beneficial effects:
[0015] This invention involves inserting a needle into the hematoma in the target area for cutting and puncturing. Water is then injected through syringes connected to the first and second water injection tubes, flowing out through the inlets of the first and second flushing tubes to flush the target hematoma area. A vacuum system connected to the suction tube then aspirates the fluid and hematoma from the target area through an suction port formed at the lower end of the needle. This cyclical flushing method quickly and effectively drains the postoperative hematoma, reducing its impact on surrounding tissues and promoting healing. The three chambers can operate simultaneously, diluting the hematoma while aspirating fluid, greatly improving the time required to clear the hematoma and significantly increasing the success and cure rates.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0027] Example 1:
[0028] like Figure 1-3As shown, the VABB postoperative hematoma cutting and puncture circulating irrigation device of this utility model includes: a needle tube 1, with a needle tip 2 disposed below the needle tube 1; a first irrigation tube 3, connected to one side of the needle tube 1; and a second irrigation tube 4, connected to the other side of the needle tube 1. The needle tube 1, the first irrigation tube 3, and the second irrigation tube 4 are integrally formed. A suction tube 5 is connected above the needle tube 1. A first water injection tube 6 is connected to one side of the first irrigation tube 3, and a second water injection tube 7 is connected to one side of the second irrigation tube 4. A first liquid inlet 8 is disposed below the first irrigation tube 3, and a second liquid inlet 9 is disposed below the second irrigation tube 4. An adsorption port 11 is formed at the lower end of the needle tip 2.
[0029] In this embodiment, the needle 2 is inserted into the hematoma in the target area for cutting and puncture. Water is then injected through a syringe connected to the first water injection tube 6 and the second water injection tube 7, and flows out through the inlet 8 of the first flushing tube 3 and the second flushing tube 4 to flush the target hematoma area. Then, the vacuum system connected to the suction tube 5 is used for suction, and the accumulated fluid and hematoma in the target area can be suctioned out through the suction port 11 formed at the lower end of the needle 2. Through circulating flushing, the postoperative hematoma can be drained quickly and effectively, reducing the impact of the hematoma on the surrounding tissues and promoting healing. The three chambers can work simultaneously, diluting the hematoma and suctioning the accumulated fluid at the same time, which greatly improves the time for clearing the hematoma and has a clear effect, significantly improving the success rate and cure rate of treatment. At the same time, this needle can complete cutting, puncture, flushing and drainage in one puncture, without the need for a second puncture, reducing the patient's pain.
[0030] Specifically, the one-piece design of needle tube 1, first flushing tube 3 and second flushing tube 4 eliminates multiple connecting parts, reduces the risk of leakage and failure rate, improves the reliability of the system, reduces the operation time of nursing staff, improves work efficiency, can quickly and effectively drain postoperative hematoma, and reduce the impact of hematoma on surrounding tissues. The main function of the vacuum system is to help attract fluid and hematoma by generating negative pressure. Specifically, the vacuum system mainly includes a vacuum pump, connecting pipes and valves and regulators.
[0031] The first flushing pipe 3 is connected to a first water injection pipe 6 on one side, and the second flushing pipe 4 is connected to a second water injection pipe 7 on one side. Water can be injected through the first water injection pipe 6 and the second water injection pipe 7 at the same time, or one water injection pipe can be used to inject water, and the other water injection pipe can be used as an air inlet. In this way, full negative pressure and half negative pressure can be switched during negative pressure suction, so that the suction effect is better.
[0032] like Figure 1 and Figure 2As shown, the needle tube 1 is connected between the first flushing tube 3 and the second flushing tube 4, and the suction tube 5 is located between the first water injection tube 6 and the second water injection tube 7. Multiple suction holes 10 are provided on the side of the needle tube 1. By opening multiple suction holes 10 on the bottom side of the needle tube 1, it can be used in conjunction with the adsorption port 11 to draw liquid, which increases the liquid flow area and improves the drainage efficiency.
[0033] like Figure 1 and Figure 2 As shown, needle 1 is thin and 5mm long. Needle 1 is thin and the needle tip 2 is designed to resemble a sharp blade, which can quickly break the skin and cut cleanly, matching the incision after VABB surgery. This ensures consistency between the puncture site and the postoperative wound. The thin needle design minimizes pressure on the skin to reduce the impact on blood supply to the skin edge, reducing the likelihood of poor postoperative skin healing and maintaining the aesthetics of VABB surgery.
[0034] Example 2:
[0035] like Figure 4-6 As shown, the VABB postoperative drainage assembly includes a drainage tube 12, with an inlet pipe 13 inside the drainage tube 12. The inlet pipe 13 is connected to the water injection valve 15 through the water inlet 14. One end of the drainage tube 12 is connected to the drainage bag. Drainage grooves 16 are provided on both sides of the bottom of the drainage tube 12. The drainage tube 12 is thin and oval. After circulation irrigation, for some special populations, such as patients with underlying diseases such as hypertension, diabetes, or taking anticoagulants, in order to prevent the recurrence of hematoma, the indwelling matching drainage tube 12 can be considered. The drainage tube 12 is thin and oval, which is suitable for small wounds after cutting and puncture, and can minimize the pressure on the skin to reduce the impact on the blood supply to the skin edge. Water can be injected through the water injection valve 15, and aspiration can be performed through the drainage bag connected to the drainage tube 12.
[0036] Among them, the drainage groove 16 has a supporting function and is not easily flattened, while the drainage groove 13 is a single opening, which has a wider drainage surface compared to the opening design.
[0037] Working principle: The needle 2 is inserted into the hematoma in the target area for cutting and puncture. Water is then injected through the syringe connected to the first water injection tube 6 and the second water injection tube 7, and flows out through the inlet 8 of the first flushing tube 3 and the second flushing tube 4 to flush the target hematoma area. Then, the vacuum system connected to the suction tube 5 is used for suction. The accumulated fluid and hematoma in the target area can be suctioned out through the suction port 11 formed at the lower end of the needle 2. Through circulating flushing, the postoperative hematoma can be drained quickly and effectively, reducing the impact of the hematoma on the surrounding tissues and promoting healing. The three chambers can work simultaneously, diluting the hematoma and suctioning the accumulated fluid at the same time, which greatly improves the time for clearing the hematoma and has a clear effect, significantly improving the success rate and cure rate of treatment. At the same time, this needle can complete cutting, puncture, flushing and drainage in one puncture, eliminating the need for a second puncture and reducing the patient's pain.
