Description

Technical Field

[0001] This invention relates to the field of auxiliary devices for thyroid ablation, specifically to an isolation device for thyroid ablation. Background Technology

[0002] In the field of clinical medicine, thyroid ablation, as a common minimally invasive surgery, is widely used in the treatment of thyroid diseases due to its advantages of minimal trauma and rapid recovery. However, the traditional thyroid ablation procedure lacks specialized isolation devices, leading to numerous pain points in the surgical and postoperative care processes, seriously affecting surgical safety, patient comfort, and wound healing outcomes.

[0003] During the surgical procedure, the existing process has the following shortcomings: First, the disinfectant, blood, and other droplets generated in the neck during the operation can easily spread and contaminate the surgical area, increasing the risk of infection; Second, the temperature of the isolation fluid injected during the operation is relatively high, and the low-temperature isolation barrier formed by the isolation fluid is not good, which can easily cause neck discomfort due to overheating. During the postoperative care phase, patients also face many inconveniences: in order to compress and stop bleeding, patients need to press the gauze on their neck for a long time, which can easily cause hand soreness; when swelling and pain occur in the neck after surgery, patients need to hold an ice pack for ice application, but their hands are easily chilled by contact with the ice pack, making it difficult to hold for a long time, and holding it continuously can also cause hand soreness; in addition, head movements during the recovery process can easily pull on the neck wound, interfering with the wound healing process and prolonging the recovery period. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an isolation device for thyroid ablation procedures, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An intraoperative isolation device for thyroid ablation includes: Neck base; A neck isolation assembly includes a back neck shield and a front neck shield. The back neck shield has an absorbent pad inside and an external pull groove on its back. The absorbent pad has a pull ring in the middle. The front neck shield includes a base box that is inserted into the back neck shield. The top surface of the base box has a cover seat, and the cover seat contains an abutment component. The base box contains a cooling component. The neck isolation assembly includes the following configuration: In the surgical procedure, the back neck shield is placed inside the neck base, and the front neck shield is installed off-center on one side of the back neck shield. The cooling element cools the isolation fluid, and the absorbent pad absorbs the dripping fluid from the neck. Postoperative mode: The back neck shield and front neck shield are attached to the patient's neck to cover the wound and support the patient's head; absorbent pads are gathered to compensate for the gap between the back neck shield and the neck; cooling pads are applied to the wound with ice.

[0006] Furthermore, it also includes a head base, one end of which is provided with a neck base; the top of the head base is provided with a head isolation component, which includes a slider, an arc cover, and a baffle.

The sliders are positioned by locking studs; the surface of the arc cover has a mesh structure, and the outer end of the arc cover has a baffle that extends downward into the head base and contacts the patient's head.

[0007] Furthermore, the outer pull groove extends along the width direction of the back and neck cover, and when the absorbent pad is laid on the inner wall of the back and neck cover, the pull ring is aligned with the outer pull groove; the pull ring is used as a pull-out structure for the absorbent pad.

[0008] Furthermore, the neck shield has locking grooves at both ends, and the two ends of the absorbent pad are embedded in the locking grooves. A second locking component for positioning the two ends of the absorbent pad is installed inside the locking groove; a first locking component is provided outside the pull groove. Postoperative mode: When the absorbent pad needs to be gathered to restrain the neck, two second locking components lock the absorbent pad, and the redundant part of the absorbent pad is pulled out through the outer pull groove. The first locking component locks the redundant part that is pulled out. When the absorbent pad needs to be fully removed, the second locking component is unlocked, and the absorbent pad is pulled out through the outer pull groove.

[0009] Furthermore, the first locking component includes a first pressure plate, a first side plate, and a second side plate. The first side plate and the second side plate are symmetrically arranged on both sides of the outer pull groove and on the outer wall of the back neck cover. One end of the first pressure plate is rotatably connected to the first side plate, and the other end of the first pressure plate is provided with a locking plate. The inner wall of the second side plate is provided with a first locking hole adapted to the locking plate. The second side plate is made of elastic material.

The adjusting stud spirally passes through the screw groove, and the horizontal clamping plate slides horizontally through the guide groove. One end of the horizontal clamping plate is rotatably connected to the adjusting stud, and the other end is vertically fixedly connected to the vertical clamping plate. The vertical clamping plate slides in the receiving groove, and the end of the absorbent pad is received in the receiving groove. The vertical clamping plate clamps and positions the end of the absorbent pad.

[0011] Furthermore, the internal cavity of the base box is an assembly square groove, and a second magnetic plate is provided at each of the four corners of the assembly square groove. The cover is flush with and embedded in the assembly square groove. Metal structures that attract the second magnetic plates are embedded at the four corners of the bottom surface of the cover. The base box has through holes at both ends, and the inner end of the through holes is located at the bottom of the cover. The bottom surface of the base box has an arc-shaped contact port, and a flexible adhesive film is embedded inside the arc-shaped contact port.

[0012] Furthermore, a rectangular hole is provided in the center of the surface of the cover, and an adjustment arc groove is symmetrically provided on the inner wall of the rectangular hole. The arc of the adjustment arc groove is the same as the arc of the arc contact opening. The abutment component includes a movable block with movable posts at both ends. The movable posts are damped and slidably embedded in the adjusting arc groove. The outer wall of the movable posts is symmetrically provided with movable grooves. Multiple sets of springs are embedded inside the movable grooves. The outer ends of the multiple sets of springs are provided with conical locking posts. The conical locking posts extend axially and are slidably embedded in the movable grooves. The top and bottom surfaces of the adjusting arc groove are provided with locking tooth grooves.

[0015] This invention provides an isolation device for thyroid ablation procedures. Compared with existing technologies, it has the following advantages: 1. During ablation, when the back neck shield and the front neck shield are installed in a staggered manner, the upper surface of the front neck shield forms a platform for placing the instrument; after the operation, the back neck shield and the front neck shield can be connected to the outside of the neck, which can surround the wound and support the patient's head, avoiding the folds at the wound site from being pulled and causing pain. 2. During the procedure, the isolation fluid injection tube needs to be inserted from the side. Based on the characteristics of the isolation fluid injection tube layout and the staggered layout of the anterior neck shield, the isolation fluid injection tube is designed to pass through the anterior neck shield. The anterior neck shield can constrain and position the isolation fluid injection tube. A cooling device can be placed inside the anterior neck shield to cool the isolation fluid injection tube, ensuring that the isolation fluid injected into the thyroid gland is at a low temperature, thereby forming a uniform low temperature barrier, improving the safety of ablation, and reducing patient discomfort. After the procedure, the cooling device remains inside the anterior neck shield and can be used to apply cold compresses to the wound. 3. An abutment component is installed inside the cover. The abutment component can press down on the corresponding area of ​​the cooling component to apply ice only to the area around the wound, avoiding frostbite to normal skin and achieving precise pain relief and swelling reduction. 4. During the procedure, the absorbent pad inside the neck shield can quickly absorb droplets (disinfectant, blood, etc.) from the neck, keeping the surgical area clean and reducing the risk of infection. After the procedure, the absorbent pad can be removed directly, and it can also be folded up to compensate for the gap between the neck shield and the neck, making the neck shield more securely positioned.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, 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] To address the technical problems in the background section, the following isolation device for thyroid ablation is provided: Combination Figures 1-12 As shown, the present invention provides an isolation device for thyroid ablation surgery, comprising: a head base 100, the top of which is provided with a head isolation component; a neck base 200, which is disposed at the middle of one end of the head base 100; and a neck isolation component, which includes a back neck shield 300 and a front neck shield 500, wherein an absorbent pad 400 is embedded inside the back neck shield 300; the front neck shield 500 includes a base box 510 and a cover 520, wherein the bottom surface of the base box 510 is inserted into the top surface of the back neck shield 300. The top surface of the box 510 is covered by a cover seat 520; the bottom surface of the base box 510 has an arc-shaped contact opening, and a flexible adhesive film 530 is embedded inside the arc-shaped contact opening. A cooling component 700 is embedded inside the base box 510, and the cooling component 700 is located between the flexible adhesive film 530 and the cover seat 520; a set of abutment components 600 are slidably installed on the surface of the cover seat 520; the two ends of the base box 510 have through holes 511, and the inner end of the through holes 511 is located at the bottom of the cover seat 520. Neck isolation components include the following modes: In the intraoperative mode, the back neck shield 300 is placed inside the neck base 200, and the front neck shield 500 is installed off-center on one side of the back neck shield 300. The upper surface of the front neck shield 500 serves as a platform for placing instruments. The contact component 600 presses down the isolation fluid injection tube 800 to fit against the cooling component 700, and the cooling component 700 cools the input isolation fluid. The absorbent pad 400 absorbs the intraoperative dripping fluid from the neck. In the postoperative mode, the back neck shield 300 and the front neck shield 500 are attached to the outside of the patient's neck to surround the wound and support the patient's head; the contact component 600 presses down on the cooling component 700 to fit the neck wound to apply pressure and ice to the wound; the absorbent pad 400 is gathered to compensate for the gap between the back neck shield 300 and the neck.

[0020] In the above scheme: 1. During ablation, when the back neck shield 300 and the front neck shield 500 are installed in a staggered manner, the upper surface of the front neck shield 500 forms a platform for placing the instrument; after the operation, the back neck shield 300 and the front neck shield 500 can be connected to the outside of the neck, which can surround the wound and support the patient's head, avoiding the folds at the wound site from being pulled and causing pain. 2. During the procedure, the isolation fluid injection tube 800 needs to be inserted from the side. Based on the layout characteristics of the isolation fluid injection tube 800 and the staggered layout of the anterior neck shield 500, the isolation fluid injection tube 800 is designed to pass through the anterior neck shield 500. The anterior neck shield 500 can restrain and position the isolation fluid injection tube 800. A cooling element 700 can be placed inside the anterior neck shield 500 to cool the isolation fluid injection tube 800, ensuring that the isolation fluid injected into the thyroid gland is at a low temperature, thereby forming a uniform low temperature barrier, improving ablation safety, and reducing patient discomfort. After the procedure, the cooling element 700 remains inside the anterior neck shield 500 and can be used for cold compresses on the wound. 3. An abutment component 600 is installed inside the cover. The abutment component 600 can press down on the corresponding area of ​​the cooling component 700 to apply ice only to the area around the wound, avoiding frostbite to normal skin and achieving precise pain relief and swelling reduction. 4. During the operation, the absorbent pad 400 inside the back neck shield 300 can quickly absorb the dripping fluid (disinfectant, blood, etc.) in the neck, keeping the surgical area clean and reducing the risk of infection. After the operation, the absorbent pad 400 can be removed directly, and the absorbent pad 400 can also be folded up to compensate for the gap between the back neck shield 300 and the neck, making the back neck shield 300 more securely positioned.

[0021] In this embodiment, the head isolation assembly includes a slider 110, an arc cover 120, and a baffle 130. The arc cover 120 is provided with sliders 110 at both bottom ends. The surface of the head base 100 is provided with a groove adapted to the sliders 110. The sliders 110 are positioned by locking studs 111. The surface of the arc cover 120 is provided with a mesh structure. The outer end of the arc cover 120 is provided with a baffle 130. The baffle 130 extends downward into the head base 100 and abuts against the patient's head.

[0022] In the above scheme: the slider 110 of the head isolation component slides along the groove of the head base 100, and the position of the arc cover 120 can be adjusted according to the patient's head shape, and then positioned by the locking stud 111; the baffle 130 extends downward to the head base 100 and abuts against the head, restricting the lateral / longitudinal movement of the head and avoiding positioning deviation during surgery. The arc cover 120 covers the upper part of the patient's head, and its mesh structure ensures breathability while preventing hair and dander from falling into the surgical area, further improving the cleanliness of the surgical environment.

[0023] After surgery, the front neck shield 500 and the back neck shield 300 will be connected immediately to allow for cold compresses to compress the wound gauze. However, at this time, the absorbent pad 400 is still inside the back neck shield 300. To solve the above problem, in this embodiment, the back neck shield 300 has an outer pull groove 310 in the middle of its outer wall, which extends along the width of the back neck shield 300. The absorbent pad 400 has a pull ring 410 in the middle of its outer wall. When the absorbent pad 400 is laid on the inner wall of the back neck shield 300, the pull ring 410 is aligned with the outer pull groove 310. The pull ring 410 is used as a pull-out structure for the absorbent pad 400.

[0024] In the above solution: the outer pull groove 310 of the back and neck cover 300 and the pull ring 410 of the absorbent pad 400 form a special removal structure: when the absorbent pad 400 is laid out, the pull ring 410 is aligned with the outer pull groove 310. When replacing, there is no need to disassemble the back and neck cover 300. The absorbent pad 400 can be completely pulled out by simply applying force outward through the pull ring 410. The operation is convenient and improves the efficiency of postoperative care.

[0025] To adapt the absorbent pad 400 to both postoperative scenarios of "peripheral wound restraint (reducing swelling)" and "complete replacement," in this embodiment, a first locking component 320 is provided on the outside of the outer pull groove 310, and locking grooves 330 are provided at both ends of the back neck cover 300. The two ends of the absorbent pad 400 are embedded in the locking grooves 330, and a second locking component 340 for positioning the two ends of the absorbent pad 400 is installed inside the locking grooves 330. In postoperative mode: when the absorbent pad 400 needs to be pulled back to restrain the neck, the two second locking components 340 lock the absorbent pad 400, and the redundant part of the absorbent pad 400 is pulled out through the outer pull groove 310, and the first locking component 320 locks the redundant part pulled out. When the absorbent pad 400 needs to be completely removed, the second locking component 340 is unlocked, and the absorbent pad 400 is pulled out through the outer pull groove 310.

[0026] In the above scheme: When neck restraint is required after surgery, the second locking component 340 fixes both ends of the absorbent pad 400. After the redundant part is pulled out through the outer pull groove 310, the first locking component 320 locks the redundant part, so that the pad fits tightly against the neck and helps to reduce swelling around the wound.

[0027] When the padding needs to be replaced, the second locking component 340 can be unlocked, and the padding can be fully pulled out through the pull ring 410 without any additional operation, thus balancing the needs of restraint and replacement.

[0028] The first and second locking components respectively secure the redundant part to the end of the pad, preventing loosening during restraint; when fully removed, only the second locking component 340 needs to be unlocked, making the operation simple and improving the flexibility of care.

[0029] In this embodiment, the first locking component 320 includes a first pressure plate 321, a first side plate 323, and a second side plate 324. The first side plate 323 and the second side plate 324 are symmetrically arranged on both sides of the outer pull groove 310 and on the outer wall of the back neck cover 300. One end of the first pressure plate 321 is rotatably connected to the first side plate 323, and the other end of the first pressure plate 321 is provided with a locking plate 322. The inner wall of the second side plate 324 is provided with a first locking hole 325 adapted to the locking plate 322. The second side plate 324 is made of elastic material.

[0030] In the above solution: the first pressure plate 321 of the first locking component 320 rotates around the first side plate 323, and the locking plate 322 directly engages with the first locking hole 325 of the second side plate 324 without tools; the second side plate 324 is made of elastic material and can deform when engaged, ensuring that the locking plate 322 is tightly embedded and preventing loosening. The cooperation structure between the locking plate 322 and the first locking hole 325 can stably lock the redundant part of the absorbent pad 400, and it is not easy to fall off even with slight patient movement, ensuring the neck restraint effect. At the same time, when unlocking, the locking plate 322 can be removed simply by prying the elastic second side plate 324, which is convenient to operate.

[0031] In this embodiment, the locking groove 330 includes a screw groove 331, a guide groove 332, and a receiving groove 333 arranged from the outside to the inside. One end of the guide groove 332 is connected to the screw groove 331, and the other end is connected to the receiving groove 333. The side of the receiving groove 333 is an open structure. The second locking component 340 includes an adjusting stud 341, a horizontal clamping plate 342, and a vertical clamping plate 343. The adjusting stud spirally passes through the screw groove 331, and the horizontal clamping plate 342 slides horizontally through the guide groove 332. One end of the horizontal clamping plate 342 is rotatably connected to the adjusting stud 341, and the other end is vertically fixedly connected to the vertical clamping plate 343. The vertical clamping plate 343 is slidably placed in the receiving groove 333, and the end of the absorbent pad 400 is received in the receiving groove 333. The vertical clamping plate 343 clamps and positions the end of the absorbent pad 400.

[0032] In the above scheme: after the end of the absorbent pad is received into the receiving groove 333, the longitudinal clamping plate 343 clamps it tightly from the side, and with the spiral locking structure of the screw groove 331 (the adjusting stud 341 does not loosen when there is no external force), it ensures that the end of the pad does not come off when pulled or constrained, thus improving the reliability of the fixation.

[0033] In this embodiment, the internal cavity of the base box 510 is an assembly square groove 512. A second magnetic plate 513 is provided at each of the four corners of the assembly square groove 512. The cover 520 is flush with the assembly square groove 512. Metal structures that are attracted to the second magnetic plate 513 are embedded at the four corners of the bottom surface of the cover 520.

[0034] In the above scheme: the assembly groove 512 of the base box 510 provides an embedding reference for the cover 520. When the cover 520 is embedded, its bottom metal structure automatically attracts the second magnetic plate 513 in the assembly groove 512, achieving precise docking without repeated adjustments and saving preoperative preparation time.

[0035] The fixed position of the contact component 600 makes it impossible to adjust the contact point according to the wound location (post-operative), leading to uneven cooling or misalignment of the ice pack. Furthermore, the contact pressure is uncontrollable, easily causing patient discomfort due to excessive pressure or affecting the effect due to insufficient pressure. To solve these problems, in this embodiment, a rectangular hole 521 is formed in the center of the surface of the cover 520. The inner wall of the rectangular hole 521 is symmetrically provided with adjusting arc grooves 522, the curvature of which is the same as the curvature of the arc-shaped contact opening. The contact component 600 includes a movable block 610, with movable posts 630 at both ends. The movable posts 630 are damped and slidably embedded in the adjusting arc grooves 522, and the outer wall of the movable posts 630 is symmetrically provided with movable grooves. 631, multiple sets of springs 632 are embedded inside the movable groove 631, and the outer ends of the multiple sets of springs 632 are provided with conical locking posts 633. The conical locking posts 633 extend axially and slide into the movable groove 631. The top and bottom surfaces of the adjusting arc groove 522 are provided with locking tooth grooves 5221. The conical locking posts 633 are elastically engaged in the locking tooth grooves 5221. The middle part of the moving block 610 is provided with a screw hole, and the screw hole is spirally penetrated by a contacting screw post 620.

[0036] In the above scheme: 1. The moving post 630 of the contact component 600 slides along the adjusting arc groove 522 of the cover 520 (the arc groove curvature matches the arc-shaped contact port and adapts to the neck curve), and the cone-shaped locking post 633 elastically engages with the locking tooth groove 5221, which can fix the moving block 610 at any position to ensure that the contact point is accurately aligned with the wound. 2. The contact stud 620 of the movable block 610 spirally passes through the screw hole. By rotating the contact stud 620, the downward pressure can be finely adjusted to avoid excessive pressure causing patient discomfort, or insufficient pressure causing poor adhesion of the injection tube (insufficient cooling) and poor ice pack effect, thereby improving the safety and effectiveness of use.

[0037] In this embodiment, the cooling component 700 includes a base film 710, with multiple sets of cooling hoses 720 embedded at intervals inside the base film 710. The cooling hoses 720 extend along the width direction of the base box 510, and are filled with a cooling medium, such as medical cryogenic gel. The base film 710 has female buckles 740 at both ends, and male buckles 750 are provided on both sides of the bottom of the assembly square groove 512. The male buckles 750 and female buckles 740 engage with each other. The area of ​​the base film 710 is larger than the cross-sectional area of ​​the arc-shaped contact opening. The surface of the base film 710 is provided with limiting bands 730 at intervals, and the limiting bands 730 are placed between adjacent cooling hoses 720. In the intraoperative mode, the isolation fluid injection tube 800 passes through each limiting band 730 to fit with the cooling hose 720; In the postoperative mode, the moving block 610 moves along the adjusting arc groove 522 so that the contact stud 620 contacts the corresponding area of ​​the cooling hose 720 to fit the wound.

[0038] In the above scheme: 1. A limiting band 730 is provided on the base film 710 of the cooling component 700. After the isolation liquid injection pipe 800 passes through the limiting band 730, it can be tightly attached to the cooling hose 720 to ensure that the injection pipe is in contact with the cooling component 700 throughout the process, so that the isolation liquid cools down evenly and avoids local temperatures that are too high or too low. 2. Multiple sets of cooling hoses 720 are distributed at intervals. The contact studs 620 can be pressed down on the corresponding area of ​​the cooling hose 720 to apply ice only to the area around the wound, avoiding frostbite to normal skin. 3. The base film 710 is engaged with the male snap-fit ​​750 of the base box 510 via the female snap-fit ​​740, and is firmly fixed without shifting. 4. The cooling hose 720 extends along the width of the base box 510, conforming to the curved contour of the neck, improving patient comfort and cooling effect.

[0039] In this embodiment, slots 514 are provided at both ends of the bottom surface of the base box 510, and an insert plate 515 is provided in the middle of the slot 514. The docking surface of the back neck cover 300 is provided with docking seats 350 vertically and symmetrically. A docking groove 351 is provided inside the docking seat 350. A first magnetic plate 352 is embedded inside the docking seat 350. The docking seat 350 is inserted into the slot 514, and the insert plate 515 is inserted into the docking groove 351 and is attracted and connected to the first magnetic plate 352.

[0040] In the above scheme: 1. The slot 514 of the front neck shield 500 base box 510 mates with the docking seat 350 of the back neck shield 300, and the insert plate 515 mates with the docking groove 351 to form a dual positioning structure, which can quickly achieve alignment in two modes without repeated adjustments. 2. The first magnetic plate 352 inside the docking seat 350 adsorbs the insertion plate 515 inserted into the docking groove 351, further enhancing docking stability, avoiding tilting of the instrument platform during surgery (causing the instrument to fall) or loosening of the perimeter after surgery (causing wound exposure and contamination), and improving the overall reliability of the device.

[0041] Working principle and usage process of this invention: S1. Preoperative preparation: The neck shield 300 is embedded in the neck base 200, the absorbent pad 400 is laid in the neck shield 300, the pull ring 410 faces the outer pull groove 310, and the adjusting stud 341 is rotated outward, thereby driving the longitudinal clamping plate 343 to move outward, so as to clamp the end of the absorbent pad 400 in the receiving groove 333. The base box 510 is misaligned and fitted onto one end of the back neck cover 300. The docking seat 350 is inserted into the slot 514 of the base box 510, and the insert plate 515 is inserted into the docking groove 351. The first magnetic plate 352 attracts the insert plate 515. The cooled component 700, after being frozen, is placed inside the base box 510. The female buckles 740 at both ends of the base film 710 are covered by the male buckles 750, so that the cooled component 700 is placed in close contact with the arc-shaped contact port. The isolation fluid injection tube 800 is passed through the various limiting bands 730 on the base film 710 so that the isolation fluid injection tube 800 fits into the cooling hose 720. S2, Intraoperative Ablation: The patient lies flat on the bed with the head placed in the head base 100 and the neck placed in the back neck shield 300; move the arc shield 120 so that the baffle 130 touches the patient's head, and finally tighten the locking stud 111. Apply disinfectant to the neck; excess disinfectant will flow down the neck and be absorbed by the absorbent pad 400. Under the guidance of an ultrasound probe, anesthesia is injected and punctured. The needle at one end of the isolation fluid injection tube 800 is inserted into the thyroid gland in the neck. The nurse operates the needle at the other end of the isolation fluid injection tube 800. When the isolation fluid injection tube 800 passes through the cooling element 700 area, the isolation fluid is cooled down and then injected into the thyroid gland, thereby forming a low-temperature isolation barrier at the thyroid gland. Ablation is performed using an ablation needle under the guidance of an ultrasonic probe. S3. Postoperative care: After the ablation procedure, gauze is applied to the outside of the ablation wound. The front neck shield 500 and the back neck shield 300 are assembled facing each other, and the docking seat 350 is inserted into the slot 514. The front neck shield 500 and the back neck shield 300 form a protective structure around the neck. The moving block 610 moves along the adjusting arc groove 522, and the conical locking post 633 gradually engages with each locking tooth groove 5221. Under the action of the locking force of the conical locking post 633 and the locking tooth groove 5221, the moving block 610 can be kept in the specified position. Rotating the contact stud 620 causes it to contact the corresponding cooling hose 720, which moves outward. The flexible membrane 530 adapts to the deformation, allowing the cooling hose 720 to be used for both ice application to the wound and compression of gauze, thereby reducing swelling, relieving pain, and stopping bleeding. The depth of rotation of the contact stud 620 can be controlled to change the pressure. When ice application is not needed, simply unscrew the contact stud 620 outward to detach the cooling hose 720 from the wound. During recovery, the front neck shield 500 and back neck shield 300 can protect the wound from contamination and support the patient's head to prevent excessive head tilting or tilting, which could stretch the wound. When it is necessary to change the gauze, observe the wound, or re-freeze the cooling unit 700, the front neck shield 500 and the back neck shield 300 can be separated.

[0042] This embodiment can achieve the following effects: 1. When the back neck shield 300 and the front neck shield 500 are installed in a staggered manner, the upper surface of the front neck shield 500 forms a stable instrument placement platform, avoiding contamination of surgical instruments and reducing errors in instrument transfer during surgery; the absorbent pad 400 inside the back neck shield 300 can quickly absorb neck drops (disinfectant, blood, etc.), keeping the surgical area clean and reducing the risk of infection.

[0043] 2. The base box 510 and cover seat 520 of the front neck cover 500 form a closed space, which can stably hold the isolation fluid injection tube 800 and cool it through the cooling component 700, ensuring that the isolation fluid injected into the thyroid gland forms a uniform low temperature barrier, improving the ablation safety and reducing patient discomfort.

[0044] 3. The back neck shield 300 and the front neck shield 500 are connected to form a neck protection structure, which physically isolates external pollutants and protects the wound. The whole device (combined with the head base 100) can lift the patient's head, limit excessive head tilting or tilting, and prevent the wound from being delayed in healing due to traction.

[0045] 4. The contact component 600 of the front neck shield 500 can press down on the cooling component 700 to achieve "compression hemostasis + ice pack analgesia" in one: the flexible film 530 adapts to the curve of the neck, and the cooling component 700 fits the wound area. It promotes hemostasis through pressure and relieves swelling and pain through low temperature. No additional tools are required, simplifying the nursing process.

[0046] 5. The back neck cover 300 and the front neck cover 500 can be quickly docked / separated through the slot 514, docking seat 350 and magnetic adsorption structure (first magnetic plate 352), which facilitates intraoperative mode switching, postoperative wound observation and replacement of cooling component 700, and makes the operation efficient.

[0047] 6. The absorbent pad 400 achieves a multi-functional fit of "adsorption-constraint-replacement" through the outer pull groove 310, pull ring 410 and locking components (first and second locking components 340), which can be flexibly adjusted according to postoperative needs (such as constraining the neck to reduce swelling or completely replacing it), improving the flexibility of use.

[0048] 7. The limiting band 730 on the base film 710 can fix the isolation fluid injection tube 800, so that it fits tightly against the cooling hose 720, ensuring that the injection tube is in contact with the cooling component 700 throughout the process. The isolation fluid is cooled evenly during the delivery process, avoiding patient discomfort caused by local temperature fluctuations and ensuring the stability of the low temperature isolation barrier effect. The cooling hose 720 extends along the width of the base box 510, adapts to the arc contour of the neck, improves the fit with the injection tube, and further ensures the uniformity of cooling.

[0049] 8. Multiple sets of cooling hoses 720 are spaced apart, and with the movable abutment component 600 (moving block 610 is positioned along the adjusting arc groove 522), the cooling hoses 720 in the corresponding area can be pressed down in a targeted manner, so that ice can be applied only to the area around the wound, avoiding frostbite to normal skin, and achieving precise pain relief and swelling reduction.

[0050] 9. The base membrane 710 has an area larger than the arc-shaped contact port, and in conjunction with the adaptive deformation of the flexible adhesive membrane 530, ensures that the cooling hose 720 can fit tightly against the neck wound, improving the ice pack and compression effect. The base membrane 710 is securely fixed by engaging with the male buckle 750 of the base box 510 via the female buckle 740, preventing the cooling component 700 from shifting due to patient movement during or after surgery, and ensuring accurate positioning for cooling / ice packing.

[0051] 10. The cooling component 700 is an independent component that can be pre-frozen and quickly installed into the base box 510. When changing it after surgery, it can be removed simply by separating the cover 520. The operation is convenient and does not affect wound protection.
