Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be arbitrarily combined with each other.

[0025] like Figures 1-17 As shown, the cranioplasty fixation device 100 of this utility model embodiment includes an outer shell helmet 1 and one or more gaskets 2a, 2b, 2c, 2d disposed within the outer shell helmet 1. The gaskets 2a, 2b, 2c, 2d are disposed within the outer shell helmet 1 of the cranioplasty fixation device 100, and each gasket 2a, 2b, 2c, 2d includes a gasket body 20, which has a gradually varying thickness.

[0026] In one exemplary embodiment, the cranial orthopedic fixator 100 further includes an inner liner 3 disposed within the outer shell helmet 1, and gaskets 2a, 2b, 2c, and 2d disposed between the outer shell helmet 1 and the inner liner 3. The inner liner 3 has a similar profile to the outer shell helmet 1 to improve patient comfort.

[0027] This invention designs the main body 20 of the pads 2a, 2b, 2c, and 2d to have a gradually varying thickness. This allows them to be installed behind the outer shell helmet 1, helping to stabilize the craniocerebral fixation device 100 on the patient's head. This ensures that the patient maintains the position of the outer shell helmet 1 in different sleeping positions, preventing rotation and displacement. Additionally, some craniocerebral fixation device designs have an open side; this open side also requires padding for support to help secure the craniocerebral fixation device 100. The specific placement of the open area depends on its location within the helmet.

[0028] The gradually varying thickness of the gasket bodies 20 of the gaskets 2a, 2b, 2c, and 2d of this utility model will not affect the fit between the inner liner 3 and the helmet shell 1 after installation. The overall thickness transition is very natural and will not cause any foreign body sensation during wear.

[0029] like Figures 1-7 As shown, the outer shell helmet 1 includes a cheek guard portion 11, a nipple portion 14, a back neck portion 13, and a forehead portion 12. A pad 2 is disposed at at least one of the cheek guard portion 11, the nipple portion 14, the back neck portion 13, and the forehead portion 12. The pad 2 includes multiple pads, each including a cheek guard pad 2a, a nipple pad 2d, a back neck pad 2c, and a forehead pad 2b, respectively disposed in the cheek guard portion 11, the nipple portion 14, the back neck portion 13, and the forehead portion 12. The cheek guard pad 2a, the nipple pad 2d, the back neck pad 2c, and the forehead pad 2b all have a gradually changing thickness and a shape adapted to the cheek guard portion 11, the nipple portion 14, the back neck portion 13, and the forehead portion 12.

[0030] The multiple gaskets 2a, 2b, 2c, and 2d have different shapes to correspond to the connection points of the outer shell helmet 1, so that they fit more snugly and look better after being connected to the outer shell helmet 1.

[0031] like Figure 1 , Figure 2 As shown, the pad bodies 20 of pads 2a, 2b, 2c, and 2d gradually increase in thickness from the top to the bottom along the contour of the cranial orthopedic fixator 1, thereby maintaining a high degree of fit with the outer shell helmet 1 or the outer shell helmet 1 and the inner liner 3, so that no gaps are generated between the outer shell helmet 1 and the pad body 20, improving the wearing comfort of the cranial orthopedic fixator 1.

[0032] like Figures 1-7As shown, the main body 20 of the pads 2a, 2b, 2c, and 2d is arc-shaped to conform to the contour of the cranial orthopedic fixator 1, thereby achieving a higher degree of fit with the outer shell helmet 1 or the outer shell helmet 1 and the inner liner 3, so that no gaps are generated between the outer shell helmet 1 and the inner liner 3, further improving the wearing comfort of the cranial orthopedic fixator 1.

[0033] like Figure 9 , Figure 15 As shown, along the contour of the cranial orthopedic fixator 100, the height on both sides gradually increases from the top to the bottom, forming an arc-shaped inclined surface 201. The thickness variations of the pads 2a, 2b, 2c, and 2d in this embodiment are not simple straight-line cuts, but rather an arc-shaped design, allowing for a closer fit to the patient's head.

[0034] In this embodiment of the invention, the pads 2a, 2b, 2c, and 2d are all made of soft materials. For example, the pads 2a, 2b, 2c, and 2d can be made of TPU material, which is both soft and elastic to fit the skull orthopedic fixator 100 of different shapes, and can provide ideal support, and is not easily deformed after wearing.

[0035] like Figure 8 , Figure 10 , Figure 11 , Figure 12 As shown, the gasket body 2 has a first gasket surface and a second gasket surface opposite to each other. The first gasket surface is configured to fit the contour of the inner surface of the outer shell helmet 1 and is provided with a first connecting structure 21. The second gasket surface is configured to fit the contour of the outer surface of the inner liner 3 and is provided with a second connecting structure 4. The first connecting structure 21 is configured to be detachably connected to the inner side of the outer shell helmet 1, and the second connecting structure 4 is configured to be detachably connected to the outer side of the inner liner 3.

[0036] In this embodiment of the present invention, the first connecting structure 21 is one or more locking posts extending from the first pad surface toward the inner side of the outer shell helmet 1. The locking post includes a post body 210 and a buckle 211. The side wall of the locking post 210 is provided with a plurality of slots 212 extending from the post body 210 to the buckle 211 at intervals along the circumference, so that the locking post 210 can elastically shrink and open in the radial direction.

[0037] like Figure 10 , Figure 16 As shown, the second pad surface is provided with a groove 22 for receiving the second connecting structure 4. The second connecting structure 4 is an adhesive structure, which is a Velcro. The thickness of the Velcro is consistent with the recess depth of the groove 22, so that the inner lining 3 will not be affected by the thickness of the Velcro itself after the Velcro is attached, making the overall precision more accurate and the comfort higher.

[0038] like Figure 11 , Figure 12As shown, the outer shell helmet 1 has retaining holes 10 that engage with the retaining posts 210 of the gaskets 2a, 2b, 2c, and 2d. The inner liner 3 has an adhesive structure (not shown) that engages with the adhesive structure of the gaskets 210; the adhesive structure of the inner liner is Velcro. One of the adhesive structures of the gaskets 2a, 2b, 2c, and 2d and the adhesive structure of the inner liner 3 is the rough side of the Velcro, and the other is the hook side of the Velcro.

[0039] In this embodiment of the invention, the gaskets 2a, 2b, 2c, and 2d are connected to the outer shell helmet 1 via a snap-fit ​​mechanism. Two protruding locking posts 210 are designed on the back of the gaskets 2a, 2b, 2c, and 2d. The top of the locking post 210's buckle 211 is slightly wider than the post body 210. Two corresponding retaining holes 10 are provided on the outer shell helmet 1. The locking posts 210 on the back of the gaskets 2a, 2b, 2c, and 2d can be inserted into the retaining holes 10 of the outer shell helmet 1. The locking posts 210 have a cross-shaped groove 212, which causes a slight deformation during insertion, making the insertion process smoother. The wider top of the locking post 210 is designed so that after being inserted into the hole on the outer shell helmet 1, the wider top fits precisely on the outside of the retaining hole 10, further enhancing the overall stability of the gaskets 2a, 2b, 2c, and 2d after installation.

[0040] like Figure 13 , Figure 17 As shown, the pad assembly of this utility model embodiment includes one or more sets of pads, each set of pads including multiple pads 2a, 2b, 2c, 2d with the same shape but different thicknesses, to adapt to the growth changes of the user's head shape and replace them.

[0041] The outer shell helmet 1 features multiple spacers 2a, 2b, 2c, and 2d of varying thicknesses H1, H2, H3, H4, and H5. The first connecting structure 21 of spacers 2a, 2b, 2c, and 2d is also easily detachable. Therefore, orthodontists can quickly adjust the thickness of spacers 2a, 2b, 2c, and 2d according to the actual wearing condition of the craniotomy fixator 100, thus improving the success rate of fitting the craniotomy fixator 100. Furthermore, when the patient's head shape changes, the thickness of spacers 2a, 2b, 2c, and 2d can be adjusted to better suit the current situation. The thickest points of H1, H2, H3, H4, and H5 correspond to 1mm, 2mm, 3mm, 4mm, and 5mm, respectively.

[0042] When wearing the cranial orthopedic fixator 100, gaps can easily form in several areas, such as the cheek baffles 11 and the left and right mastoid processes 14, causing displacement and rotation of the cranial orthopedic fixator 100, which can affect the corrective effect. By pre-reserving the thickness of the spacers 2a, 2b, 2c, and 2d required for the cheek baffles 11 and the left and right mastoid processes 14, the cranial orthopedic fixator 100 will be manufactured with the spacers of the reserved thickness attached to the corresponding positions. In this way, the cranial orthopedic fixator 100 can be stably placed on the user's head, preventing displacement and rotation.

[0043] The cranioplasty fixator 100 is designed with shims 2a, 2b, 2c, and 2d of corresponding thicknesses that can be installed, thereby improving the success rate of the initial fitting of the cranioplasty fixator 100. After the cranioplasty fixator 100 has been worn for a period of time, the user's head circumference will increase and its shape will change. Therefore, the strategy of using the initially designed shims 2a, 2b, 2c, and 2d may become ineffective over time. At this point, the patient can remove the shims 2a, 2b, 2c, and 2d used at the beginning and replace them with shims 2a, 2b, 2c, and 2d of different thicknesses, so that the overall stability of the cranioplasty fixator 100 remains unaffected after wearing.
