Description

Technical Field

[0001] This invention relates to the field of postoperative care equipment technology, and in particular to an integrated postoperative cold-pressure headgear structure for transoral endoscopy. Background Technology

[0002] Pneumatic transoral endoscopic thyroid cancer surgery is a common endoscopic surgical procedure in thyroid surgery. Endoscopic thyroid surgery has gained increasing popularity among doctors and patients in recent years due to its advantages such as minimal trauma, rapid postoperative recovery, and good cosmetic results. In particular, the approach, which operates through the oral vestibule, avoids damage to the floor of the mouth. Furthermore, the oral mucosa has strong repair capabilities, resulting in a low risk of infection and high surgical safety. It is currently the most widely used natural orifice endoscopic surgical approach in the field of thyroid surgery both domestically and internationally. Compared to pneumatic transoral endoscopy, pneumatic transoral endoscopy offers advantages such as: no carbon dioxide-related complications, less surgical smoke, reduced risk of tumor implantation, easier management of bleeding points, and easier detection of lymphatic leakage. Because this type of surgery is performed in the oral cavity and pharynx, postoperative care mainly faces two major challenges.

[0003] The oral cavity and pharynx have rich blood supply and loose structure, making them prone to oozing, bleeding and significant edema after surgery. This not only increases the patient's suffering, but in severe cases, hematoma can compress the airway and even endanger life.

[0004] Currently, the routine clinical nursing method involves patients holding ice packs and applying them intermittently to the submandibular and anterior neck areas, followed by rough bandaging with elastic bandages for pressure. This method has significant drawbacks: the pressure cannot be precisely controlled or evenly distributed; if too loose, the hemostatic and swelling-reducing effects are poor; if too tight, it affects blood supply to the head and breathing. The cold source cannot be stably fixed, and the ice pack is prone to slipping, leading to discontinuous cold therapy. Furthermore, the patient's holding of the pack greatly restricts their postoperative activity and rest. To ensure postoperative safety and treatment, patients often require the placement of an endotracheal tube for assisted ventilation. Currently, medical tape is often used to directly fix the tube to the patient's cheek, nose, and neck skin. However, the tape is prone to loosening due to sweat and oil, leading to tube slippage and serious complications. Additionally, the multiple tubes intertwined and tangled create a messy appearance, making it difficult for nursing staff to observe and manage. Therefore, an integrated postoperative cold pressure headgear structure for transoral endoscopic surgery is needed to solve these problems. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An integrated post-oral endoscopic cold-pressure headgear structure includes a headgear section, which includes an elastic face mask. Two elastic webbing bands are symmetrically sewn onto the right side of the elastic face mask. One elastic webbing band has a Velcro strap (B) attached to its end, and the other elastic webbing band has a Velcro strap (A) attached to its end. Velcro straps A and B are attached using Velcro. A chin restraint band is sewn onto the bottom front of the elastic face mask. A rubber support plate is located at the bottom of the elastic face mask, with a pressure application area at the bottom of the rubber support plate. A tubular portion is located at the bottom of the elastic face mask. Velcro straps A and B are connected using Velcro, allowing for adjustment of the tightness of the elastic face mask worn by the patient. The pressurization component includes a jaw and neck airbag pad located at the bottom of the inner wall of the elastic mask. The front of the jaw and neck airbag pad is connected to an air inlet tube, and a pressure relief valve is provided on the surface of the air inlet tube. A miniature manual inflation balloon is provided at the end of the air inlet tube. The front of the jaw and neck airbag pad is connected to the miniature manual inflation balloon (similar to the inflation device of a blood pressure monitor) and the pressure relief valve through the air inlet tube. Medical staff can precisely adjust the pressure in the jaw and neck airbag pad and cheek airbag pad in each area according to the patient's specific condition and medical orders. The bundled tube section includes a threaded liner that is threadedly connected to the bottom end of the rubber support plate. Several rubber frames are equidistantly arranged around the inner wall of the threaded liner. The inner end face of each rubber frame is connected and fixed to the surface of the silicone tube. The threaded liner and the rubber support plate adopt a modular connection method with threaded connection, which facilitates the disassembly, adjustment and replacement of the threaded liner.

[0007] Preferably, a gel ice pack holder is inserted into the front of the rubber support plate through a placement groove. The inner wall end face of the placement groove of the rubber support plate is provided with a water-absorbing padding layer. The gel ice pack held by the gel ice pack holder is soft and can perfectly conform to the curve of the patient's jaw and front neck. The pressure distribution is uniform, and the phase change process can maintain cryotherapy for a long time in a specific temperature range. It has a long lifespan, is economical and environmentally friendly. It usually has medical-grade outer packaging, is not easy to leak, and has a dry surface. The water-absorbing padding layer on the inner side of the rubber support plate can solve the dripping problem.

[0008] Preferably, both the Velcro A and Velcro B have perforated grooves on their surfaces, and a latex pad A is provided at the center of the inner wall of Velcro A. The perforated groove design of Velcro A and Velcro B can improve breathability and prevent the skin area on the back of the head from being blocked when wrapped.

[0009] Preferably, the jaw and neck airbag pad has an internal support frame with a U-shaped structure. The jaw and neck airbag pad is connected to the cheek airbag pads on both sides through pipes. The cheek airbag pads are installed on the inner walls of the elastic mask on both sides. The cheek airbag pads have an internal liner. The internal support frame and liner of the jaw and neck airbag pads and the cheek airbag pads convert spherical pressure into uniform plate force, avoiding the common problem of tightness in the middle and looseness at the edges in traditional bandage compression.

[0010] Preferably, a latex pad B is provided on the back of the jaw and neck airbag pad. The surface of the latex pad B is designed with an inclination. A bending groove is opened at the connection between the latex pad B and the jaw and neck airbag pad. The inclination design of the latex pad B can fit to the corner of the patient's mandible, ensuring the fit effect of the elastic mask on the patient's mandible when it is taut. The elastic mask is made of a high-elasticity, breathable composite fabric (such as nylon and spandex blend) to provide uniform baseline wrapping pressure.

[0011] Preferably, the inner wall of the silicone tube is surrounded by a plurality of silicone vertical plates A, wherein three silicone vertical plates A form a group, and the upper and lower ends of the three silicone vertical plates A are connected to silicone arc plates. When the reserved tube is inserted into the silicone tube, the silicone vertical plates A can be deformed and shifted under pressure, and the shifted silicone vertical plates A adhere to the surface of the reserved tube to form resistance.

[0012] Preferably, an auxiliary pipe fitting is provided on the inner wall of the threaded liner between two adjacent rubber frames. The auxiliary pipe fitting includes two hook plates symmetrically arranged on the inner wall of the threaded liner. Several silicone vertical plates B are equidistantly arranged on the inner wall of the hook plates. A guide is provided at the bottom end of the threaded liner. By passing the auxiliary pipe through the hook plates, the layout of the hook plates is carefully planned, which can guide and fix pipes with different functions separately and in an orderly manner, making the pipe route clear and neat, which greatly facilitates nursing observation and recording.

[0013] Preferably, the guide includes a plurality of guide rods fixed around the bottom end of the threaded liner. Each guide rod has a telescopic sleeve fitted at its bottom end, and the bottom end of the telescopic sleeve is connected to an upper frame ring. The bottom end of the upper frame ring is connected and fixed to the lower frame ring through a connecting rod arranged around it. The position of the upper frame ring can be changed and adjusted according to the length of the reserved pipe. The positions of the upper frame ring and the lower frame ring can be suspended and extended by the cooperation of the guide rods and the telescopic sleeve.

[0014] Preferably, the lower section of the guide rod is provided with three rubber retaining rings at equal intervals, the inner wall of the telescopic sleeve is provided with annular grooves that are adapted to the rubber retaining rings at equal intervals, and the left and right sides of the telescopic sleeve are provided with through strip grooves. By moving the telescopic sleeve on the surface of the guide rod, the telescopic length of the upper frame ring can be adjusted and changed.

[0015] The present invention has at least the following beneficial effects: 1. This invention achieves precise and controllable local pressure, effectively improving hemostasis and swelling reduction. By setting up inflatable jaw and neck airbags and cheek airbags, and in conjunction with pressure release valves and miniature manual inflatable airbags, medical staff can precisely adjust and maintain the pressure within an effective and safe range according to the patient's specific condition and medical orders. The unique internal support frame and liner structure inside the airbag can convert the spherical expansion pressure of the airbag into a uniform plate-like force, avoiding the problem of uneven pressure distribution in traditional bandaging methods. It can effectively compress and stop bleeding, reduce edema, and prevent tissue ischemia or necrosis caused by excessive local pressure.

[0016] 2. This invention integrates cold compress and pressure functions, achieving synergistic treatment and improving patient comfort. By designing a special gel ice pack holder and rubber support plate, the soft gel ice pack can be stably fixed, making it perfectly conform to the physiological curve of the patient's jaw and anterior neck. This ensures close contact and efficient temperature transfer in the cold treatment area. Compression reduces local blood flow, while cold compress promotes vasoconstriction. The dual mechanisms work synergistically to significantly enhance the effects of postoperative hemostasis and swelling reduction, while avoiding frostbite that may be caused by direct contact, thus improving the comfort and continuity of treatment.

[0017] 3. Through the silicone tube, silicone vertical plate, hook plate and adjustable guide in the tubing section, tubes with different functions such as endotracheal tubes can be guided and fixed in an orderly manner, making the tube path clear and neat, which is convenient for nursing observation and management. In particular, the telescopic and adjustable guide rod, in conjunction with the upper and lower frame rings, can adapt to different tube lengths and suspend and support the tube, effectively buffering the tube's own weight or accidental pulling force, thereby greatly reducing the risk of tube slippage, displacement or unplanned extubation, and ensuring the safety of postoperative patients.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] Reference Figure 1-7 An integrated cold-pressure headgear structure for post-oral endoscopic surgery includes a headgear section 1, which includes an elastic face mask 11. Two elastic webbing bands 12 are symmetrically sewn on the right side of the elastic face mask 11. One elastic webbing band 12 is connected to a Velcro band B14 at its end, and the other elastic webbing band 12 is connected to a Velcro band A13 at its end. The Velcro band A13 and the Velcro band B14 are attached by Velcro. A chin restraint band 18 is sewn to the bottom front of the elastic face mask 11. A rubber support plate 15 is provided at the bottom of the elastic face mask 11, and a pressure part 2 is provided at the bottom of the rubber support plate 15. A bundle tube part 3 is provided at the bottom of the elastic face mask 11. The Velcro band A13 and the Velcro band B14 are connected by Velcro, which allows the tightness of the elastic face mask 11 to be adjusted at any time. The pressurization part 2 includes a jaw and neck airbag 21 located at the bottom of the inner wall of the elastic mask 11. The front of the jaw and neck airbag 21 is connected to an air inlet tube 22, and a pressure relief valve 23 is provided on the surface of the air inlet tube 22. A miniature manual inflatable airbag is provided at the end of the air inlet tube 22. The tube bundle 3 includes a threaded liner 31 that is threadedly connected to the bottom of the rubber support plate 15, and several rubber frames 32 are equidistantly arranged around the inner wall of the threaded liner 31. The inner end face of each rubber frame 32 is connected and fixed to the surface of the silicone tube 33.

[0023] A gel ice pack holder 16 is inserted into the front of the rubber support plate 15 through the placement groove, and an absorbent pad layer is provided on the inner wall end face of the placement groove of the rubber support plate 15.

[0024] Both Velcro tape A13 and Velcro tape B14 have hollowed-out grooves on their surfaces, and a latex pad A17 is provided at the center of the inner wall of Velcro tape A13.

[0025] The jaw and neck airbag cushion 21 has an internal support frame 24 with a U-shaped structure. The left and right sides of the jaw and neck airbag cushion 21 are connected to the cheek airbag cushion 26 through pipes. The cheek airbag cushion 26 is installed on the inner wall of the left and right sides of the elastic mask 11. The cheek airbag cushion 26 has an internal liner frame 27.

[0026] The back of the jaw and neck airbag cushion 21 is provided with a latex pad B25. The surface of the latex pad B25 is designed to be inclined, and a bending groove is provided at the connection between the latex pad B25 and the jaw and neck airbag cushion 21.

[0027] The inner wall of the silicone tube 33 is surrounded by several silicone vertical plates A34, with three silicone vertical plates A34 forming a group, and silicone arc plates 35 connected to the upper and lower ends of the three silicone vertical plates A34.

[0028] An auxiliary pipe fitting 36 is provided on the inner wall of the threaded liner 31 between two adjacent rubber frames 32. The auxiliary pipe fitting 36 includes two hook plates 361 symmetrically arranged on the inner wall of the threaded liner 31. Several silicone vertical plates B362 are equidistantly arranged on the inner wall of the hook plates 361. A guide 37 is provided at the bottom end of the threaded liner 31.

[0029] The guide 37 includes a plurality of guide rods 371 that are fixed around the bottom end of the threaded liner 31. Each guide rod 371 has a telescopic sleeve 373 fitted at its bottom end, and the bottom end of the telescopic sleeve 373 is connected to an upper frame ring 374. The bottom end of the upper frame ring 374 is connected to the lower frame ring 376 through a connecting rod 375 arranged around it.

[0030] The lower section of the guide rod 371 is provided with three rubber retaining rings 372 at equal intervals. The inner wall of the telescopic sleeve 373 is provided with annular grooves that are adapted to the rubber retaining rings 372 at equal intervals. The telescopic sleeve 373 is provided with through strip grooves on the left and right sides.

[0031] The front of the jaw and neck airbag 21 is connected to a miniature manually inflatable airbag, similar to the inflation device of a blood pressure monitor, and a pressure relief valve 23 via an air inlet tube 22. Medical staff can precisely adjust the pressure in the jaw and neck airbag 21 and cheek airbag 26 in different areas according to the patient's specific condition and medical orders, achieving personalized and precise pressure application. This can effectively compress and stop bleeding while avoiding excessive local pressure that could lead to ischemia or discomfort. The threaded liner 31 and the rubber support plate 15 are connected by a modular threaded connection, which facilitates the disassembly, adjustment, and replacement of the threaded liner 31. Four rubber brackets 32 are fixed to the inner wall of the threaded liner 31 to support the silicone cylinder 33, suspending the silicone cylinder 33 at the center of the threaded liner 31. When the reserved tube passes through the center of the silicone cylinder 33, the silicone cylinder 33 can lift the reserved tube, ensuring the stability of the reserved tube placement.

[0032] The gel ice pack holder 16 supports a soft gel ice pack that perfectly conforms to the curves of the patient's jaw and front neck, providing uniform pressure distribution. The phase change process allows it to maintain cryotherapy for an extended period within a specific temperature range. It has a long lifespan, is economical and environmentally friendly, and typically comes with medical-grade outer packaging, preventing leakage and ensuring a dry surface. The absorbent padding layer inside the rubber support plate 15 solves the dripping problem. The placement compartment of the rubber support plate 15 fits the jaw and neck airbag pad 21, with the opening on the outside of the rubber support plate 15 for easy replacement. This achieves a synergistic effect of compression and cold compress. Compression reduces local blood flow, while cold compress promotes vasoconstriction. This dual effect greatly enhances hemostasis and reduces edema. The hollowed-out groove design of the Velcro straps A13 and B14 improves ventilation and prevents the back of the head from becoming stuffy when wrapped. At the same time, a latex pad A17 is placed on the inner wall of the Velcro strap A13. When the patient is lying down, the latex pad A17 can wrap and support the back of the patient's head, ensuring the patient's comfort while lying down.

[0033] The internal support frame 24 and inner liner 27 of the chin and neck airbag pad 21 and cheek airbag pad 26 are designed to convert spherical pressure into uniform plate force, avoiding the common problem of tightness in the middle and looseness at the edges in traditional bandage compression, thus improving the uniformity and safety of compression. The inclined design of the latex pad B25 can fit to the corner of the patient's mandible, ensuring the fit of the elastic mask 11 to the patient's mandible when it is taut. The elastic mask 11 is made of a highly elastic and breathable composite fabric, such as a blend of nylon and spandex, to provide uniform baseline wrapping pressure. The separate cut design of the elastic mask 11, latex pad B25, rubber support plate 15 and mandibular restraint band 18 can perfectly fit the physiological curvature of the patient's head and neck.

[0034] When the pre-installed tube is inserted into the silicone sleeve 33, the silicone vertical plate A34 can be deformed and shifted under pressure. After shifting, the silicone vertical plate A34 adheres to the surface of the pre-installed tube to form resistance. At the same time, the silicone arc plate 35 can create a reverse buckle on the surface of the pre-installed tube, effectively increasing the fixing effect of the pre-installed tube and preventing the pre-installed tube from easily loosening and being pulled and displaced. By passing the auxiliary tube through the hook plates 361, the layout of the hook plates 361 is carefully planned to guide and fix pipes with different functions separately and in an orderly manner, making the pipe routing clear and neat, which greatly facilitates nursing observation and recording. The silicone vertical plate B362 design on the inner wall of the hook plate 361 can be adapted to the outer diameter of the pipe, ensuring the insertion stability of other types of pipes and reducing the probability of pipe insertion and entanglement.

[0035] Based on the length of the reserved pipe, the position of the upper support ring 374 can be adjusted. Through the cooperation of the guide rod 371 and the telescopic sleeve 373, the positions of the upper support ring 374 and the lower support ring 376 can be suspended and extended. The cooperation of the upper support ring 374 and the lower support ring 376 can support the pipe and prevent the pipe from falling and tearing the wound on the patient's jaw, which would affect the recovery of the wound. By moving the telescopic sleeve 373 on the surface of the guide rod 371, the telescopic length of the upper support ring 374 can be adjusted. At the same time, during the adjustment process, the rubber retaining ring 372 can be embedded and locked in the annular groove inside the telescopic sleeve 373 to ensure the stability of the rubber retaining ring 372 during a single pull. Each time it is pulled, the rubber retaining ring 372 can be locked with the telescopic sleeve 373 at different positions to achieve timely self-locking fixation.

[0036] Working principle: According to Figure 3 As shown, when in use, the elastic face mask 11 is worn on the patient's face, so that the upper and lower parts of the elastic face mask 11 contact the top of the patient's head and the lower jaw respectively. Under the influence of the tension, the lower jaw restraint strap 18 can fit against the front of the lower jaw. The bottom of the elastic face mask 11 fits between the lower jaw and the front of the neck to apply pressure evenly. At the same time, the elastic webbing 12 is pulled so that the Velcro strap A13 and Velcro strap B14 are placed at the back of the patient's head for fitting and fixation. At this time, the latex pad A17 supports the back of the patient's head, which can ensure the stability of the headgear part 1. Secondly, according to Figure 4 and Figure 5As shown, the shaped gel ice pack is placed on the surface of the gel ice pack holder 16, which is inserted into the rubber support plate 15. The cold air is conducted to the periphery of the bottom tube opening of the elastic mask 11. By pressing the bulb end of the air inlet tube 22, the jaw and neck airbag pad 21 is inflated through the air inlet tube 22. The gas enters the cheek airbag pad 26 through the tube. Medical staff can precisely adjust the pressure of the airbags in each area according to the patient's specific condition and medical orders to achieve personalized and precise pressure. This can effectively compress and stop bleeding, while avoiding excessive local pressure that may cause ischemia or discomfort. The pressure of the airbag will evenly press the cooled elastic mask 11 tightly against the skin surface, ensuring close contact and efficient temperature transfer in the cold treatment area, while preventing frostbite from direct contact. At the same time, the inner support frame 24 inside the jaw and neck airbag pad 21 and the cheek airbag pad The internal liner 27 design transforms the spherical expansion pressure generated by the jaw and neck airbag 21 and cheek airbag 26 into a flat, plate-like force, which is evenly applied to the bony structure of the internal support frame 24 and the liner 27. This avoids the spherical effect that may occur when the jaw and neck airbag 21 and cheek airbag 26 directly compress, resulting in high pressure in the middle and low pressure at the edges. To ensure pressure accuracy, micro-film pressure sensors can be integrated into the jaw and neck airbag 21 and cheek airbag 26 to transmit pressure data to an external display in real time. This provides medical staff with objective and quantitative data to ensure that the pressure is always maintained within the range of 20-30 mmHg, which is generally recommended and is safe to be lower than the capillary perfusion pressure, approximately 30-35 mmHg. This perfectly avoids the risk of tissue ischemia or necrosis caused by excessive pressure. Finally, according to Figure 5 , Figure 6 and Figure 7 As shown, when the reserved tube passes through the center of the elastic face shield 11 and the rubber support plate 15, it passes through the center of the threaded liner 31 and then inserts into the silicone cylinder 33. Several silicone vertical plates A34 can be squeezed and tilted by the pipe, thereby reverse-fitting the reserved tube, increasing the friction between them, and binding the reserved tube. At the position where the pipe may bend or be stressed after being led out of the silicone cylinder 33, movable upper ring 374 and lower ring 376 are set to change the direction of force, effectively buffering the pipe's own weight or accidental pulling force, greatly reducing the risk of unplanned pipe pulling. During the position adjustment of the upper ring 374, it can be moved on the surface of the guide rod 371 through the telescopic sleeve 373, so that the rubber retaining ring 372 on the surface of the guide rod 371 is locked into the annular groove at different positions inside the guide rod 371, thereby achieving the constraint and positioning of the upper ring 374.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
