Background Technology

[0002] The ear-loop compression clamp device for postoperative treatment of earlobe keloids is a medical device specifically designed for compression therapy after surgery. Its main function is to apply continuous and stable pressure to the earlobe scar area to prevent recurrence and excessive proliferation of keloids, while simultaneously promoting postoperative tissue repair and regeneration. Traditional ear-loop compression clamp devices typically employ relatively simple structures, such as a rigid ear loop made of a single material combined with a fixation splint, or achieving compression solely through the deformation of an elastic material. While these devices can meet basic postoperative compression needs to a certain extent, they have several shortcomings.

[0003] Existing ear-hook compression clamping devices have relatively simple basic structures and lack flexibility. For example, some devices consist only of a rigid ear hook and a fixing plate. The ear hook cannot be effectively adjusted according to the shape and size of the patient's earlobe, resulting in poor wearing comfort, easy slippage or displacement, and affecting treatment effectiveness. Other devices, although using elastic materials, can only provide pressure in a single direction and with fixed force, unable to flexibly adjust the pressure angle and force according to the specific conditions of different patients' earlobe shapes and scar sites, making it difficult to achieve precise treatment. In addition, these devices usually lack effective adjustment mechanisms, cannot adapt to the treatment needs at different stages after surgery, and cannot ensure both treatment effectiveness and patient wearing experience.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] like Figure 1 and Figure 2As shown, an ear-hook type compression clamping device for postoperative treatment of earlobe keloid scars mainly includes an ear-hook tube 1 and a clamping structure 2. The ear-hook tube 1 consists of a first flexible tube 11, a second flexible tube 12, and a third flexible tube 13. The second flexible tube 12 is installed inside the end of the first flexible tube 11 with a smaller curvature, and the third flexible tube 13 is installed inside the end of the second flexible tube 12 away from the first flexible tube 11. The end of the third flexible tube 13 away from the second flexible tube 12 is connected to a spherical adjusting member 21 through a movable groove 14. The clamping structure 2 includes a clamping base plate 22 integrated with the spherical adjusting member 21, and an adjusting clamping plate 23 is provided on the other side of the clamping base plate 22. In addition, the second flexible tube 12 and the third flexible tube 13 are fitted with a number of evenly distributed adjusting protrusions 15, and the first flexible tube 11 and the second flexible tube 12 are each provided with adjusting mounting grooves 16 corresponding to the adjusting protrusions 15. The first hose 11, the second hose 12, and the third hose 13 are all made of medical-grade silicone rubber and have a hydrophilic lubricating coating on their surfaces. The angle between the clamping base plate 22 and the adjusting clamp plate 23 can be adjusted within the range of 30°-150°, with a step size of 15°.

[0029] In this implementation scheme, the multi-segment flexible tube design of the ear loop 1 provides excellent flexibility and malleability, allowing it to be bent and fixed according to the shape of the patient's earlobe, ensuring stable wear of the device. The first flexible tube 11, the second flexible tube 12, and the third flexible tube 13 are made of medical-grade silicone rubber, featuring good biocompatibility and softness. The hydrophilic lubricating coating on the surface further reduces friction during wear, improving patient comfort. The cooperation between the adjusting protrusion 15 and the adjusting mounting groove 16 allows for fine-tuning of the length and shape of the ear loop 1 as needed, enhancing the device's applicability. The clamping structure 2 is movably connected to the third flexible tube 13 via a ball-shaped adjusting element 21, enabling free adjustment at multiple angles. The angle between the clamping base plate 22 and the adjusting clamp plate 23 can be flexibly adjusted within the range of 30°-150°, with a step size of 15°, ensuring effective compression of the postoperative area of ​​the keloid scar. This design not only improves the treatment effect but also fully considers the patient's wearing experience, making it more convenient and comfortable during postoperative recovery.

[0030] like Figure 2 and Figure 3As shown, this invention relates to an ear-hook compression clamping device for postoperative treatment of earlobe keloids, aiming to provide a device that can effectively compress and prevent keloid recurrence after earlobe keloid surgery, while also being easily adjustable and able to assist in drug treatment. Its core structure includes an ear-hook tube 1 and a clamping structure 2. The ear-hook tube 1 consists of a first flexible tube 11, a second flexible tube 12, and a third flexible tube 13 nested together, connected to a ball-shaped adjusting member 21 via a movable groove 14, and further connected to the clamping structure 2. The clamping structure 2 consists of a clamping base plate 22 and an adjusting clamping plate 23, both adapted to different earlobe shapes for precise compression treatment. Simultaneously, the second flexible tube 12 and the third flexible tube 13 have external adjusting protrusions 15 and corresponding internal adjusting mounting grooves 16 for easy adjustment of the shape and length of the ear-hook tube 1. The clamping base plate 22 and the adjusting clamping plate 23 are integrally connected to earrings 24 at both ends, with a locking adjusting rod 25 passing through the inside to ensure stable wearing of the device. In addition, the adjusting clamp 23 and the clamping base plate 22 have a drug storage groove 26 near one side, which is connected to the external drug injection interface 27. The one-way check valve ensures one-way drug injection, realizing local drug treatment and improving postoperative recovery. All hoses of the device are made of medical-grade silicone rubber, and the surface hydrophilic lubricating coating enhances wearing comfort and convenience.

[0031] In this embodiment, the ear loop 1 serves as the basic support structure of the device. Its length can be customized within the range of 3-8cm according to the patient's earlobe length. The outer diameters of the first flexible tube 11, the second flexible tube 12, and the third flexible tube 13 are approximately 5mm, 4mm, and 3mm, respectively, with the inner diameter being 0.5-1mm smaller than the outer diameter to ensure stability after nesting. The medical-grade silicone rubber material has a Shore hardness between 30-50A, and the hydrophilic lubricating coating thickness is approximately 0.05-0.1mm. Medical-grade polyvinylpyrrolidone (PVP) material is used. The adjusting protrusion 15 is hemispherical, with a height of 1-2mm and a diameter of 2-3mm. It is evenly distributed in a circle every 5-10mm along the outer wall of the second flexible tube 12 and the third flexible tube 13. The depth of the adjusting mounting groove 16 matches the height of the adjusting protrusion 15.

[0032] The spherical adjusting element 21 in clamping structure 2 has a diameter of approximately 4mm, a smooth, burr-free surface, and a clearance of 0.1-0.2mm when mating with the movable groove 14. The clamping base plate 22 and adjusting clamp plate 23 are made of medical-grade stainless steel, with a thickness of 0.5-1mm, a width of 8-12mm, and a length of 15-20mm. Their surfaces are polished to a roughness Ra≤0.8μm. The angle between them is adjusted via a miniature ratchet mechanism with 24 teeth, corresponding to a 15° adjustment step. The earring 24 has an inner diameter of 3-5mm, and the locking adjusting rod 25 uses a M1.5-M2 miniature screw made of medical-grade titanium alloy with an anodized surface.

[0033] The drug storage groove 26 has a depth of 1-2 mm and a volume of approximately 0.1-0.3 mL. The external drug injection port 27 uses a Luer-Lock connector with a diameter of 3-5 mm. The one-way check valve is made of silicone rubber and has an opening pressure of 0.05-0.1 MPa to ensure smooth drug injection and prevent backflow. All component connections are bonded with medical-grade silicone rubber adhesive with a bonding strength ≥0.5 MPa to ensure the overall reliability and safety of the device.

[0034] In the above implementation scheme, the implementation methods of the existing technical solutions and means are mainly reflected in the selection of medical-grade silicone rubber material and processing technology. During the processing of medical-grade silicone rubber, 100 parts by weight of silicone rubber base rubber are mixed evenly with 50-80 parts of medical-grade reinforcing agent, 10-20 parts of medical-grade plasticizer, and 5-10 parts of medical-grade crosslinking agent. This mixture is then passed through a two-roll mill 3-5 times, with the roll temperature controlled at 40-60℃. After discharge, the mixture is vulcanized in a vacuum flat vulcanizing machine at a vulcanization temperature of 120-150℃ for 10-20 minutes to produce the first hose 11, the second hose 12, and the third hose 13. When preparing the hydrophilic lubricating coating, medical-grade polyvinylpyrrolidone (PVP) and deionized water are mixed at a mass ratio of 1:10-15 and stirred until completely dissolved. Then, an appropriate amount of medical-grade crosslinking agent is added, and the coating liquid is uniformly coated onto the surface of the hose using a dip-coating process. The hose is then dried in an 80-100℃ hot air circulating oven for 5-10 minutes to form a coating of uniform thickness.

[0035] The steps for using this device are as follows:

[0036] Device preparation: Ensure that all parts of the device are clean and dry, check whether the multi-section hose structure of the ear loop 1 is intact, whether the adjusting protrusion 15 and the adjusting mounting groove 16 fit smoothly, whether the ball adjusting part 21 of the clamping structure 2 rotates flexibly in the movable groove 14, whether the locking adjusting rod 25 is not loose, and whether the medicine storage groove 26 and the external medicine injection interface 27 are not blocked or damaged.

[0037] Size and shape adjustment: Based on the length and shape of the patient's earlobe, press the adjustment protrusion 15 to make it slide along the adjustment mounting groove 16, adjust the length and bending angle of the ear hook tube 1 so that it fits naturally with the patient's earlobe.

[0038] Wearing device: Hang the ear loop 1 on the patient's earlobe. Be careful to wear it gently to avoid unnecessary pulling on the ear.

[0039] Clamping force and angle adjustment: The distance between the clamping base plate 22 and the adjusting clamp plate 23 is adjusted by rotating the locking adjustment rod 25, so that it is lightly clamped on the keloid scar area of ​​the earlobe. According to the specific shape of the scar area and treatment needs, the angle of the clamping structure 2 is finely adjusted by rotating the ball-shaped adjustment component 21 in the movable groove 14 to ensure precise and comfortable compression. The included angle between the clamping base plate 22 and the adjusting clamp plate 23 can be adjusted within the range of 30°-150°, in increments of 15°, to adapt to the earlobe shape of different patients.

[0040] Medication filling if required: If medication is needed, use a disposable medical syringe connected to the external injection port 27 to slowly inject the medication. The one-way check valve will automatically open to inject the medication. After injection, ensure that the injection port 27 is properly sealed to prevent medication leakage.

[0041] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
