Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a surgical incision support and compression device for thyroid surgery. Background Technology

[0002] Thyroid surgery is a surgical treatment for thyroid diseases. It aims to cure the disease, relieve symptoms, or prevent the condition from worsening by removing part or all of the thyroid tissue. This surgery is suitable for a variety of thyroid diseases, including thyroid nodules, thyroid tumors, hyperthyroidism, and large goiters that affect breathing or swallowing.

[0003] After surgeries such as thyroid surgery, the incision site requires stable support and moderate compression to promote healing and reduce complications. Existing incision support and compression devices typically use a layer of medical bandage for incision compression. While medical bandages provide some pressure, they lack a stable support structure. Patient head movements or neck movements can easily cause the compression position to shift, affecting the compression effect and even pulling on the incision, delaying healing. Furthermore, overly tight bandages can restrict neck movement, affecting patient comfort and potentially causing local blood circulation disorders due to prolonged compression, leading to swelling and pain. Ordinary bandages are usually made of cotton or synthetic fibers, whose fiber structure is relatively loose and has limited capacity to absorb exudate. When the amount of exudate from the incision is slightly large, the bandage quickly reaches absorption saturation. With patient neck movements, such as turning the head or swallowing, the exudate accumulated in the bandage can easily shift. This shift can cause exudate to seep from the edges of the bandage, contaminating the patient's clothing and the surrounding environment, increasing the risk of infection. Summary of the Invention

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-7 As shown, a surgical incision support and compression device for thyroid surgery includes a support 1 and two elastic bands 2. Both elastic bands 2 are fixed to the outside of the support 1. One end of the elastic band 2 is fixed to a support 3. A compression layer 4 is provided inside the support 3. The compression layer 4 includes an outer layer 41 disposed inside the support 3, a middle layer 42 fixed to the inner wall of the outer layer 41, and an inner layer 43 embedded in the inner wall of the middle layer 42.

[0020] Support 1, as the core support structure, is located at the back of the patient's neck or shoulder, providing a stable base for elastic band 2 and compression layer 4. Elastic band 2 utilizes the resilience of elastic material to adjust the compression force according to the contour of the patient's neck. Elastic band 2 is made of elastic fiber composite material, with cotton yarn or polyester yarn as the base material, wrapped with spandex and nylon elastic yarn, taking into account breathability and elastic recovery rate. Spandex provides high elasticity, nylon enhances abrasion resistance, and cotton yarn improves breathability, making it suitable for scenarios that require frequent adjustment or long-term wear. Compression layer 4 directly compresses the postoperative incision, while reducing pressure marks when adhering to the skin, absorbing exudate, and keeping the incision dry.

[0021] The mounting plate 5 is fixed to one side of the outer layer 41. The inner wall of the support base 3 is fixed with a mounting base 6. The mounting base 6 is provided with a mounting assembly 7. The mounting assembly 7 includes a connecting plate 71 fixed to one side of the mounting plate 5. Multiple sets of limiting brackets 72 are fixed to one side of the connecting plate 71. A sliding column 73 is slidably connected to the inner wall of the mounting base 6. A limiting block 74 is fixed to the outer side of the sliding column 73, and the outer side of the limiting block 74 is engaged with the inner wall of the limiting bracket 72. An anti-slip pad 75 is fixed to one side of the limiting block 74.

[0022] Rotating the mounting plate 5 causes the connecting plate 71 to rotate, which allows the limiting frame 72 to be locked on the outside of the limiting block 74, thereby installing the mounting plate 5 and the pressure layer 4. The sliding column 73 slides inside the mounting base 6, which facilitates the alignment of the limiting frame 72 and the limiting block 74. The anti-slip pad 75 is made of silicone, which improves the locking stability of the limiting frame 72 and the limiting block 74.

[0023] The fixing sleeve 8 is located on one side of the elastic band 2. The inner wall of the fixing sleeve 8 is slidably connected to the drainage tube 9. The outer side of the fixing sleeve 8 is equipped with an annular airbag 10. The outer side of the drainage tube 9 is fitted with a positioning clip 11.

[0024] The drainage tube 9, connected to an external negative pressure device, continuously drains exudate from the body, keeping the incision dry and clean, reducing leakage of exudate around the tube, and avoiding excessive pressure that could affect the drainage effect. The fixing sleeve 8 is used to support the drainage tube 9. Meanwhile, the annular airbag 10 can be inflated. The inflated annular airbag 10 can make close and stable contact with the patient's body, effectively preventing the device from shifting or loosening during use, thus ensuring the stability of the pressure. At the same time, the inflated annular airbag 10 has a certain degree of flexibility and elasticity, which can better conform to the patient's body curves, reduce local pressure concentration on surrounding tissues, reduce patient discomfort during use, and allow the patient to wear the device more comfortably during postoperative recovery.

[0025] A silicone pad 12 is fixed to the inner wall of the support base 3, and the silicone pad 12 is annular.

[0026] The silicone pad 12 has good elasticity and flexibility, which can evenly distribute the pressure of the device on the skin around the incision, avoid excessive local pressure, thereby reducing the discomfort caused by compression and allowing patients to wear the device more comfortably during postoperative recovery.

[0027] The outer layer 41 is made of highly elastic silicone, the middle layer 42 is made of memory foam, and the middle layer 42 is cut into an arc shape to match the surgical incision, reducing pressure marks when it fits the skin. The inner layer 43 is made of sodium carboxymethyl cellulose, and the inner layer 43 is used to absorb exudate.

[0028] The outer layer 41, made of highly elastic silicone, adapts to neck movements through elastic deformation, maintaining structural stability while compressing the incision. This prevents displacement of the compression layer 4 or uneven compression due to patient movement. The memory foam has slow rebound properties and can automatically shape according to the incision contour, forming an arc-shaped structure that closely conforms to the skin. Even if the patient moves their neck, the memory foam can maintain its conformity to the incision through deformation, ensuring continuous and effective compression. Sodium carboxymethyl cellulose is a highly absorbent material that can quickly absorb blood and tissue fluid seeping from the incision, preventing exudate from accumulating on the incision surface and avoiding maceration damage caused by exudate soaking the skin.

[0029] The inner cavity of the mounting base 6 has multiple sets of limiting grooves 13, and multiple sets of positioning blocks 14 are fixed on the outer side of the sliding column 73. The outer side of the positioning block 14 is engaged with the inner wall of the limiting groove 13. A cross-shaped handle 15 is fixed on one side of the sliding column 73.

[0030] After the installation plate 5 is connected to the sliding column 73, press the handle 15 to make the positioning block 14 snap into the limiting groove 13, which improves the stability of the installation plate 5 after installation. When disassembling the installation plate 5, pull the handle 15 to pull the positioning block 14 out of the limiting groove 13, which will cause the compression layer 4 to separate from the patient's incision, making it convenient to disassemble and replace the compression layer 4 later.

[0031] The inner wall of the mounting base 6 is threaded with a limiting plate 16 for pressing the sliding column 73, and a knob 17 is fixed on one side of the limiting plate 16.

[0032] Rotate knob 17 to install limit plate 16 inside mounting base 6, so that limit plate 16 presses against slide column 73 and positioning block 14, locking the position of compression layer 4.

[0033] A reinforcing seat 18 is fixed to one side of the support 1, and an anti-wear pad 19 is fixed to one side of the reinforcing seat 18.

[0034] By having the reinforcing base 18 and the anti-abrasion pad 19 adhere to the skin, pressure is dispersed and slippage is prevented, ensuring that the compression layer 4 acts on the incision. The anti-abrasion pad 19 is made of medical foam material with a porous internal structure, which can compress and disperse pressure through the pores, and its soft surface further reduces friction.

[0035] A breathable antibacterial layer 20 is fixed to one side of the elastic band 2. The breathable antibacterial layer 20 achieves breathability through microporous polyester fibers, reducing sweat accumulation. The surface of the breathable antibacterial layer 20 is loaded with a silver ion coating. A silicone foam layer 21 is filled between the elastic band 2 and the breathable antibacterial layer 20.

[0036] The breathable and antibacterial layer 20 adopts a composite structure of antibacterial fibers and breathable substrate. The antibacterial fibers contain silver ions and chitosan antibacterial components, while the substrate is made of breathable synthetic fibers such as polyester or polyamide fibers, or modified materials of natural fibers. The porous structure between the fibers allows air to circulate and at the same time removes sweat and moisture from the skin surface, keeping the incision area dry and avoiding skin problems caused by a humid environment. The silicone foam layer 21 uses silicone rubber as the matrix and is made into a porous structure through chemical foaming or physical foaming processes. The porous structure allows the silicone foam layer 21 to deform under pressure, dispersing the concentrated pressure to a larger area and avoiding damage to the skin caused by local high pressure.

[0037] A bag body 22 is fixed to one side of the breathable antibacterial layer 20, and a cold compress bag 23 is installed on the inner wall of the bag body 22.

[0038] The cold compress 23 is used in the early postoperative period to constrict blood vessels, reduce bleeding and swelling, and relieve pain. In the later postoperative period, the cold compress 23 is removed to reduce the weight of the device, improve comfort, and promote patient activity. It uses medical-grade polymer gel, such as sodium polyacrylate or polyvinyl alcohol-based gel. The microporous structure inside the gel can lock in moisture and slowly release cold energy after cooling, maintaining a low temperature for up to 2-4 hours. Before use, place the cold compress 23 in the freezer at -18℃ to -10℃ for 1-2 hours. After taking it out, insert it directly into the bag body 22 for use.

[0039] An installation sleeve 24 is fixed to the outside of the drainage tube 9. A limiting pad 25 is fixed to the outside of the installation sleeve 24. Straps 26 are fixed to both sides of the limiting pad 25. Medical tape 27 is fixed to one side of the strap 26.

[0040] The installation sleeve 24 and the drainage tube 9 are fixed by attaching medical tape 27 to the elastic band 2 to prevent the drainage tube 9 from falling off.

[0041] The top of the annular airbag 10 is connected to an inflation port 28, and one end of the drainage tube 9 is connected to a connector 29.

[0042] Using a syringe, air is slowly injected through the inflation port 28 while observing the degree of inflation of the airbag until the appropriate pressure is reached. After the airbag inflates, it fills the gap between the drainage tube 9 and the skin, forming a sealing barrier to prevent exudate from seeping out of the incision along the tube periphery, thus reducing the risk of infection. The connector 29 is connected to an external negative pressure suction device, and a continuous negative pressure is formed in the drainage tube 9 to accelerate the flow of exudate from the incision to the outside, reducing the accumulation of fluid.

[0043] Working principle: The support 1 is fixed to the back of the patient's neck or shoulder, providing a stable base for the entire device. The two elastic bands 2 are made of elastic fiber composite material, with cotton yarn or polyester filament as the base material, wrapped with spandex and nylon elastic yarn, taking into account both breathability and elastic recovery rate. Utilizing the rebound force of the elastic material, the pressure is automatically adjusted according to the contour of the patient's neck, ensuring that the compression layer 4 always fits tightly against the incision. The annular silicone pad 12 further disperses the pressure, avoiding excessive local pressure and reducing patient discomfort. The outer layer 41 is made of highly elastic silicone material, which adapts to neck movement through elastic deformation and maintains structural stability. The middle layer 42 is made of memory foam material, cut into an arc shape to match the surgical incision. It automatically shapes using slow rebound characteristics, maintaining a high fit against the incision even when the patient's neck moves, reducing pressure marks. The inner layer 43 is made of sodium carboxymethyl cellulose, which has high water absorption and can quickly absorb incision exudate, preventing bacterial growth and skin maceration damage. Rotating the mounting plate 5 drives the connecting plate 71 to rotate, causing the limiting frame 72 to lock in place. The limiting block 74 on the outside of the sliding column 73 achieves initial fixation. The silicone anti-slip pad 75 enhances the stability of the engagement. Pressing the cross-shaped handle 15 causes the positioning block 14 to engage with the limiting groove 13, further fixing the sliding column 73. Rotating the knob 17 presses the limiting plate 16 tightly against the sliding column 73, locking the position of the compression layer 4 to ensure a long-lasting and stable compression effect. After the drainage tube 9 is connected to the negative pressure suction device, the connector 29 creates a continuous negative pressure inside the drainage tube 9, accelerating the discharge of exudate. The annular airbag 10 is inflated through the inflation port 28. The air expands and fills the gap between the drainage tube 9 and the skin, forming a sealing barrier to prevent exudate leakage. The bandage 26 fixes the drainage tube 9 with medical tape 27 to prevent the drainage tube 9 from falling off. The breathable antibacterial layer 20 is made of microporous polyester fiber substrate with silver ion coating to reduce sweat accumulation and inhibit bacterial growth. The silicone foam layer 21 disperses pressure through a porous structure to avoid skin damage. A cold compress bag 23 is inserted into the bag body 22. In the early postoperative period, cold compresses constrict blood vessels and reduce bleeding and swelling. Later, the bag is removed to reduce the weight of the device.
