[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Specific implementation examples are given below.

[0027] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5This utility model provides a fixation device for postoperative ice application in maxillofacial surgery, including a fixation strap 1; characterized in that: a slide rail groove 11 is provided on both sides of the end of the fixation strap 1; a slide rail plate 12 is fixedly connected to the inner side wall of the slide rail groove 11; multiple sets of slide rail strips 13 are provided at the end of the slide rail plate 12; an adjustment groove 14 is provided on both sides of the end of the fixation strap 1; multiple sets of fixation rods 15 are fixedly connected to the inner side wall of the adjustment groove 14; a sponge sheet 16 is fixedly connected to the outer side wall of the fixation rod 15; multiple sets of ventilation holes 17 are provided in the middle of the sponge sheet 16; an adjustment column 18 is fixedly connected to the end of the fixation rod 15; a slider 19 is fixedly connected to the end of the sponge sheet 16; a connecting block 101 is fixedly connected to the end of the slider 19; the connecting block 101... A connecting piece 102 is fixedly connected to the outer wall of the connecting block 101; an insert block 103 is slidably connected to the inner wall of the connecting piece 102; multiple slots 104 are provided in the middle of the fixing strap 1; a slider 19 is slidably connected to the inner wall of the slide rail 13; a connecting block 101 is slidably connected to the outer wall of the fixing strap 1; an insert block 103 is slidably connected to the inner wall of the slot 104; a sponge sheet 16 is slidably connected to the middle of the adjusting groove 14; a fixing structure is provided on the surface of the fixing strap 1; during operation, before the device needs to be put on the patient, the ice pack is first fixed to both sides of the fixing strap through the ice pack fixing structure of the fixing strap, and then the fixing strap is put on the patient in a suitable position so that the ice pack is correspondingly placed on the patient's wound side, and then the fixing strap is adjusted by tightening or loosening. The position is adjusted to ensure the fixing strap is stably positioned on the patient's head. While the patient is wearing the ice pack, if the ice pack generates excessive cold air, the caregiver can manually pull the connecting block 101 to move the slider 19 along the track of the slide rail 13. Simultaneously, the sponge sheet 16 will slide. When the connecting block 101 is pulled to the top of the slide rail 13, the insert block 103 is inserted into the slot 104. At this point, the sponge sheet 16 is stretched and opened within the adjustment groove 14 and held in a fixed position. Simultaneously, the ventilation holes 17 on the sponge sheet 16 partially isolate the cold air emitted from the ice pack, reducing the flow rate and volume of cold air through the adjustment groove 14. The cold air is regulated by the action of the two sponge sheets 16. When lowering the temperature, the insert 103 can be pulled out from inside the 10. Then, the vent 17 is rotated to rotate the fixing rod 15, which rolls up the sponge sheet 16. This opens the flow space of the adjustment groove 14, increasing the flow rate and volume of cold air, thereby enhancing the ice pack's icing effect. This step involves setting a temperature control layer between the ice pack and the skin. When the ice pack is first fixed, the sponge sheet is raised to reduce the flow rate and volume of cold air, preventing frostbite. After the ice pack has been used for a period of time, the sponge sheet is rolled up so that the cold air released by the ice pack can be fully utilized. By controlling the flow rate and volume of cold air, the ice pack is always kept in the temperature range most conducive to reducing inflammation and swelling, enhancing the relieving effect of the ice pack on postoperative swelling and pain.

[0028] Furthermore, such as Figure 1 , Figure 3 As shown, the fixing structure includes a positioning slide plate 2; one side of the positioning slide plate 2 is fixedly connected to the fixing belt 1, and the positioning slide plate 2 is located in the adjusting groove 14; both sides of the end of the positioning slide plate 2 are provided with moving grooves 21; a sliding column 22 is slidably connected to the inner wall of the moving groove 21; a fixing block 23 is fixedly connected to the end of the positioning slide plate 2; a threaded rod 24 is rotatably connected to the inner wall of the fixing block 23; a pressing plate 25 is fixedly connected to the end of the sliding column 22; a linkage block 26 is fixedly connected to the end of the pressing plate 25; a threaded rod 24 is rotatably connected to the inner wall of the linkage block 26; and the pressing plate 25 is slidably connected to the surface of the positioning slide plate 2. During operation, when fixing the ice pack, first place both ends of the ice pack on the positioning slide plates 2 at the top and bottom, and then manually rotate the threaded rod 24 to drive the linkage block 25. The moving block 26 slides, and when the moving block 26 slides, it drives the extrusion plate 25 to slide towards the positioning slide plate 2. When the extrusion plate 25 slides, it drives the sliding column 22 to slide into the moving groove 21. Through the extrusion action of the upper and lower sides on the ice pack, the ice pack can be fixed on both sides of the fixing belt 1, so that the cold air of the ice pack can penetrate into the skin through the sponge sheet for ice application. By rotating the threaded rod 24 to different degrees, the position of the ice pack from the sponge sheet can be adjusted, so as to control the penetration effect of the cold air. At the same time, the ice pack can be quickly disassembled and replaced by the threaded rod 24. This step can control the distance between the ice pack and the sponge sheet by different degrees of clamping the ice pack, so as to adjust the penetration distance of the cold air. At the same time, the speed of rotating the threaded rod 24 makes it easy to disassemble the ice pack, improving the convenience of replacing the ice pack.

[0029] Furthermore, such as Figure 1 , Figure 2 As shown, the fixing strap 1 is fixedly connected to an insert strap 3 at one end; the insert strap 3 has multiple sets of dividing grooves 31 at one end; the insert strap 3 has multiple sets of positioning strips 32 fixedly connected to one end; the fixing strap 1 is fixedly connected to an elastic band 33; the elastic band 33 has multiple sets of adjusting strips 34 fixedly connected to one end; the adjusting strip 34 has an insertion groove 35 at one end. During operation, after the fixing strap is worn, according to the patient's head size and different comfort levels, a section of the elastic band 33 can be inserted into different dividing grooves 31. Then, the elastic band 33 that has passed through the dividing groove 31 is pulled out, and a suitable adjusting strip 34 is selected for locking. When the appropriate positioning strip 32 is locked into the corresponding insertion groove 35 of the adjusting strip 34, the fixing strap can be stabilized on the wearer's head. This step, through the connection between the positioning strip 32 and the slot of the insertion groove 35, improves the tightness of the fixing strap when the wearer wears it, reduces the shaking of the fixing strap, and improves the stability when wearing it.

[0030] Furthermore, such as Figure 2 , Figure 5As shown, the inner wall of the fixing band 1 is provided with a relaxation groove 4; multiple sets of spring groups 41 are fixedly connected to the inner wall of the relaxation groove 4; a cotton head pad 42 is fixedly connected to the end of the spring group 41; when in operation, after being worn, the elasticity of the spring group 41 and the cotton of the cotton head pad 42 allow the wearer's head to be in a relaxed state, while the fixing band 1 has a certain elastic movement. This step, by giving the wearer's head a certain amount of room to move and giving the fixing band 1 a certain amount of elastic movement, reduces the tightness of the fixing band when the wearer wears it for a long time, and improves the tightness of the head and the wearer's comfort.

[0031] Furthermore, such as Figure 1 , Figure 2 As shown, the end of the adjustment groove 14 is provided with a liner groove 5; a pad 51 is fixedly connected to the inner side wall of the liner groove 5; during operation, when worn, the pad 51 comes into contact with the skin, and cold air passes through the pad 51 to apply ice to the skin. This step can buffer the cold air through the pad 51, and at the same time, the contact between the pad 51 and the skin can improve the comfort when wearing it.

[0032] Furthermore, such as Figure 3 As shown, a tension spring 6 is fixedly connected to the end of the threaded rod 24; the tension spring 6 is fixedly connected to the linkage block 26; during operation, the tension spring 6 is initially in a compressed state. When the ice pack is clamped and fixed, the tension spring 6 generates an elastic force that acts on the linkage block 26, pushing the linkage block 26, and then pushing the extrusion plate 25 to clamp the ice pack. This step, through the elastic thrust of the tension spring 6, can increase the clamping force of the extrusion plate 25, while buffering its reaction force.

[0033] Furthermore, such as Figure 4 As shown, multiple sets of rubber strips 7 are fixedly connected to the end of the extrusion plate 25. During operation, when clamping the ice pack, the rubber strips 7 increase the contact area with the ice pack. This step increases the contact area with the ice pack by increasing the rubber strips 7, thereby increasing its friction and improving the stability when clamping and fixing the ice pack.

[0034] Working principle: Before putting the device on the patient, the ice pack is first fixed to both sides of the fixing strap using the ice pack fixing structure. Then, the fixing strap is placed in the appropriate position on the patient, so that the ice pack is positioned on the side of the patient's wound. The fixing strap is then adjusted using the tensioning device to ensure that it is stably positioned on the patient's head. While the device is on the patient's head, if the ice pack is too cold, the nursing staff can manually pull the connecting block 101 to move the slider 19 along the track of the slide rail 13, which in turn moves the sponge sheet 16. When the connecting block 101 is pulled to the top of the slide rail 13, the insert block 103 is inserted into the slot 104. At this time, the sponge sheet 16 is stretched and opened inside the adjustment groove 14 and remains fixed. In a fixed state, the ventilation holes 17 on the sponge sheet 16 partially isolate the cold air emitted by the ice pack, while reducing the flow rate and volume of cold air through the regulating groove 14. The two sponge sheets 16 regulate the cold air flow. When the cold air from the ice pack decreases, the insert 103 can be pulled out from inside the 10, and then the ventilation holes 17 are rotated to rotate the fixing rod 15, retracting the sponge sheet 16. This opens the flow space of the regulating groove 14, increasing the flow rate and volume of cold air, thereby enhancing the ice pack's cooling effect. This step, by setting a temperature control layer between the ice pack and the skin, raises the sponge sheet when the ice pack is first fixed, reducing the flow rate and volume of cold air and preventing frostbite. After the ice pack has been used for a period of time... The sponge sheet is then rolled up to ensure full utilization of the cold air released by the ice pack. By controlling the flow rate and volume of the cold air, the ice pack is kept within the temperature range most conducive to reducing inflammation and swelling, enhancing its effectiveness in relieving postoperative swelling and pain. During operation, when securing the ice pack, first place both ends of the ice pack on the upper and lower positioning slide plates 2. Then, manually rotating the threaded rod 24 will cause the linkage block 26 to slide. As the linkage block 26 slides, it causes the compression plate 25 to slide towards the positioning slide plate 2. As the compression plate 25 slides, it causes the sliding column 22 to slide into the moving groove 21. Through the compression action of the upper and lower sides, the ice pack can be secured to both sides of the fixing strap 1, allowing the cold air from the ice pack to penetrate the skin through the sponge sheet for cooling. The ice pack's position relative to the sponge pad can be adjusted by varying the degree of rotation of the threaded rod 24, thus controlling the penetration effect of the cold air. The threaded rod 24 also allows for quick removal and replacement of the ice pack. This step, by adjusting the tightness of the ice pack clamping, controls the distance between the ice pack and the sponge pad, thereby adjusting the penetration distance of the cold air. The speed of rotation of the threaded rod 24 facilitates the removal and replacement of the ice pack, improving convenience. During operation, after the fixation strap is put on, depending on the patient's head size and comfort level, a section of the elastic band 33 can be inserted into different dividing slots 31. Then, the elastic band 33 is pulled out through the dividing slot 31, and the appropriate adjusting strip 34 is selected for locking.When the appropriate positioning strip 32 is inserted into the corresponding insertion slot 35 of the adjusting strip 34, the fixing strap can be stabilized on the wearer's head. This step, through the connection between the positioning strip 32 and the slot of the insertion slot 35, improves the tightness of the fixing strap when the wearer wears it, reduces the shaking of the fixing strap, and improves the stability when wearing it. During operation, after being properly worn, the elasticity of the spring assembly 41 and the cotton-like head pad 42 allow the top of the wearer's head to be in a relaxed state, while also allowing the fixing strap 1 to have a certain elastic movement. This step, by allowing the top of the wearer's head a certain amount of room to move and providing the fixing strap 1 with a certain elastic movement, reduces the tightness of the fixing strap during prolonged wear, improving the tightness of the head and the wearer's comfort. During operation, when wearing... The pad 51 contacts the skin, allowing cold air to pass through and apply ice to the skin. This step uses the pad 51 to buffer the cold air and improve comfort during wear. During operation, the tension spring 6 is initially compressed. When clamping the ice pack, the tension spring 6 generates elastic force acting on the linkage block 26, pushing the linkage block 26, which in turn pushes the extrusion plate 25 to clamp the ice pack. This step, through the elastic thrust of the tension spring 6, increases the clamping force of the extrusion plate 25 while buffering its reaction force. During operation, the rubber strip 7 increases the contact area with the ice pack, increasing friction and thus improving the stability of clamping the ice pack.
