Description

Technical Field

[0001] The present invention relates to the field of skull repair, and in particular to a post-cranial surgery drilling repair device. Background Art

[0002] Skull drilling surgery is a method of draining fluid or blood in the skull by drilling a hole in the skull, which can treat diseases such as intracranial hematoma. However, after drilling the hole in the skull, if the skull is not repaired, the patient may experience various adverse symptoms such as inattention and memory loss. Therefore, the skull needs to be repaired after drilling. The existing skull repair method is mainly through titanium mesh repair. The steps are mainly to first cut the patient's scalp to expose the hole in the skull, and then place the pre-customized titanium mesh in the hole so that the titanium mesh can cover the hole. The titanium mesh is then fastened to the skull with screws, and the scalp is restored and sutured. Because after the titanium mesh is fastened to the skull, if it is subjected to a large impact force, it will not only cause pain to the patient, but also seriously affect the repair effect. Therefore, in the future, an auxiliary repair device is needed to protect the skull with the titanium mesh fixed to prevent the titanium mesh from being impacted.

[0003] Patent publication number CN219126734U discloses a neurosurgery clinical skull fracture repair device. When using the above device, it is necessary to first move and adjust the rubber airbag to a position that can cover the titanium mesh, then put the above device on the head, clamp the head with the clamping plate 1 and the clamping plate 2, and then clamp the stretching plate with the clamping plate, and then further fix it with the Velcro hook surface and the Velcro fleece surface. However, because the rubber airbag of the above device always maintains a tight fit with the part of the head where the titanium mesh is fixed, when the head is hit, the impact force will be preferentially transmitted to the support of the above device. The rubber airbag can cushion the impact force, but the airbag will inevitably deform under the action of the impact force, which will cause the patient's head to be subjected to some squeezing force and friction. In addition, when the patient goes up and down the stairs, the above-mentioned device may move relative to the patient's head due to inertia, resulting in bumps, which may cause the airbag to rub against the head. These situations not only easily cause discomfort to the patient, but also may affect the effect of the drilling repair. Therefore, a post-cranial drilling repair device that can reduce the friction on the repair site is now being developed. Summary of the Invention

DETAILED DESCRIPTION

[0037] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0038] Example 1

[0039] A device for repairing a burr hole after intracranial surgery, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, it includes a fixing member 1, a fixed belt net 11 is fixedly connected between the left and right sides of the upper part of the fixing member 1, and also includes a first sliding sleeve 2, the number of the first sliding sleeve 2 is two, the two first sliding sleeves 2 are respectively fixed to the left and right sides of the fixing member 1, and the first sliding sleeve 2 is slidably connected to a sliding connector 21, a protective cover 22 is fixedly connected between the rear sides of the sliding connector 21 away from each other, and the left and right sides of the protective cover 22 are fixedly connected to a connecting rod 23, and the lower front side of the connecting rod 23 is fixedly connected to a first sliding rod 24, and the first sliding rod 24 is slidably connected to the adjacent first sliding sleeve 2, and a first spring 25 is wound between the connecting rod 23 and the adjacent first sliding sleeve 2. The springs 25 are all wound around the adjacent first sliding rod 24. The rear part of the fixing member 1 is fixed with a first fixed block 26. The upper part of the first fixed block 26 is fixed with a guide rod 27. The guide rod 27 is slidably connected to the sliding member 28. The front part of the sliding member 28 is rotatably connected to the rotating seat 29. The front part of the rotating seat 29 is rotatably connected to the protective plate 210. The protective plate 210 is an arc-shaped plate with a hollow middle part. A second spring 211 is wound between the upper rear side of the sliding member 28 and the first sliding rod 24. A second spring 211 is also wound between the lower rear side of the sliding member 28 and the first fixed block 26. The two second springs 211 are both wound around the first sliding rod 24.

[0040] After the patient has undergone a cranial drilling operation, the scalp at the corresponding position needs to be cut first, and then the hole on the skull is repaired with a titanium mesh, and then the scalp is sutured back to its original position so that the scalp covers the titanium mesh. However, because the titanium mesh is just fixed on the skull, if the titanium mesh is hit at this time, not only will the patient feel pain, but the titanium mesh may also be offset or even damaged. Therefore, in order to protect the titanium mesh, the present post-cranial surgery drilling repair device can be worn for a period of time after the titanium mesh is fixed to assist in the repair of the titanium mesh. Taking the hole caused by the drilling on the back side of the skull as an example, when wearing it, the fixing part 1 needs to be put on the forehead in a surrounding manner. At this time, the fixing belt net 11 will cover the top of the head, and the protective plate 210 just rests against the part of the patient's head where the titanium mesh is fixed. Then the patient can move normally, because the protective plate 210 is an arc-shaped plate, the protective plate 210 can fit the patient's head contour more closely, so that it can move more easily with the patient's head, and because the middle part of the protective plate 210 is hollowed out, it will not affect the ventilation of the repaired part, which is conducive to repairing the hole. When the patient moves, the protective plate 210 can rotate on the rotating seat 29 to match the movement of the patient's head, and the rotating seat 29 can also rotate to a certain extent according to the movement of the protective plate 210 to match the movement of the patient's head, thereby avoiding the protective plate 210 from rubbing against the patient's head as much as possible. When the patient's head is hit from behind, the protective cover 22 will move forward, while the fixing belt net 11 and the fixing part 1 will not move. Driven by the first spring 25, the sliding connector 21 and the connecting rod 23 all move forward, so the sliding connector 21 will move forward relative to the first sliding sleeve 2, and the connecting rod 23 will drive the first sliding rod 24 to move forward, and the first spring 25 will be compressed. At this time, the first spring 25 can provide a buffering effect, so that the protective cover 22 has a distance to move forward, avoiding the protective cover 22 directly transmitting the impact force to the protective plate 210 and the patient's head, so that the patient's head may be subjected to the impact force and friction, affecting the titanium mesh repair, and then under the action of the first spring 25, the first sliding rod 24 moves backward and resets, so that the connecting rod 23, the protective cover 22 and the sliding connector 21 all move backward and reset. When the patient's head moves up and down, such as when the patient goes up and down stairs When the headrest 210 is in a stable position, the second spring 211 on the lower side is stretched and the second spring 211 on the upper side is compressed. When the headrest 210 is in a stable position, the first fixing block 26 and the guide rod 27 move downward with the headrest 1, while the position of the protective plate 210 remains unchanged. Therefore, the second spring 211 on the lower side is stretched and the second spring 211 on the upper side is compressed. When the headrest 1 is in a stable position, the first fixing block 26 and the guide rod 27 move upward with the headrest 1, while the position of the protective plate 210 remains unchanged. Therefore, the second spring 211 on the lower side is compressed and the second spring 211 on the upper side is stretched. As the headrest 210 moves up and down, the second spring 211 can provide the headrest 1 with a range of upward and downward movement.The fixing member 1 is prevented from driving the connecting rod 23, the rotating seat 29 and the protective plate 210 to move up and down together, thereby reducing the friction of the protective plate 210 on the patient's head. When the fixing member 1 stops moving relative to the patient's head, the fixing member 1 moves in the opposite direction and resets under the action of the second spring 211. When the patient needs to remove the intracranial post-operative drilling repair device, the patient first pulls the rear part of the fixing member 1 backward by hand so that the protective plate 210 no longer presses against the head. Maintaining this state, the fixing member 1 is then slowly moved upward by hand, so that the fixing member 1 drives the fixing belt net 11 away from the head. The first slide bar 24 and the first spring 25 cushion the impact force on the protective cover 22 and provide space for the protective cover 22 to move forward, preventing the protective cover 22 from being directly squeezed by the impact force on the protective plate 210, causing the protective plate 210 to exert squeezing and friction on the titanium mesh. The guide bar 27 and the second spring 211 cushion the fixing member 1, allowing the fixing member 1 to move up and down, so that the protective plate 210 does not move up and down with the fixing member 1, avoiding friction between the protective plate 210 and the titanium mesh. This can reduce the friction on the repaired area and facilitate the repair.

[0041] Example 2

[0042] On the basis of Example 1, Figure 7 、 Figure 8 and Figure 9 As shown, it also includes a clamping mechanism, which is arranged on the protective cover 22. The clamping mechanism is used to clamp the protective cover 22 on the head when the head is hit. The clamping mechanism includes a second sliding sleeve 3, and the number of the second sliding sleeves 3 is two. The two second sliding sleeves 3 are respectively slidably connected to the left and right sides of the front of the protective cover 22. The sides of the second sliding sleeves 3 that are away from each other are fixed with an impact plate 31, and a third spring 32 is wound between the impact plate 31 and the protective cover 22. The third springs 32 are all wound on the adjacent second sliding sleeves 3. The sides of the second sliding sleeves 3 that are close to each other are slidably connected with a second sliding rod 33. The sides of the second sliding rods 33 that are close to each other are fixed with a rubber pad 34, and the rubber pads 34 are squeezed and fitted with the adjacent second sliding sleeves 3.

[0043] like Figure 7 and Figure 9 As shown, it also includes a pin lock 35, and there are two pin locks 35. The pin locks 35 are both arranged between the second slide 3 and the adjacent second slide rod 33. The second slide 3 is provided with three pop-up holes 36 distributed at equal intervals, and the pop-up holes 36 are all engaged with the adjacent pin locks 35.

[0044] In the initial state, the rubber pad 34 has been in contact with the patient's head, and the pin lock 35 extends from the pop-up hole 36 closest to the patient's head. The pin lock 35 locks the position of the rubber pad 34 and the second slide bar 33. When the left and right sides of the patient's head are hit, because the impact plate 31 protrudes from the protective cover 22, the impact plate 31 will be hit first. At this time, the impact plate 31 will move to the side close to the patient's head, and the second sliding sleeve 3 will move accordingly. The third spring 32 is compressed, and the second sliding sleeve 3 will squeeze the rubber pad 34 to the side close to the patient's head. The rubber pad 34 will further clamp the two sides of the patient's head, so that the entire fixing part 1 and the protective cover 22 can be more stably fixed on both sides of the patient's head, further stabilizing the position of the protective cover 22 and the fixing part 1, and preventing the fixing part 1 and the protective cover 22 from falling. In the process of the second sliding sleeve 3 squeezing the rubber pad 34, the pin lock 35 Because it is squeezed by the second sliding sleeve 3, it will retract into the second sliding sleeve 3. As the next pop-up hole 36 on the second sliding sleeve 3 faces the pin lock 35, the pin lock 35 will pop out again, thereby locking the position of the rubber pad 34 again. When the impact force disappears, you can press the pin lock 35 by hand to retract the pin lock 35 into the second sliding sleeve 3, thereby unlocking the rubber pad 34 and the second sliding rod 33. Then, under the action of the third spring 32, the second sliding sleeve 3 and the impact plate 31 move to the side away from the patient's head and reset. Then release the pin lock 35, so that the pin lock 35 extends out from the pop-up hole 36 closest to the patient's head again. When the patient's head is hit, the rubber pad 34 further clamps the two sides of the patient's head, making the relative position between the fixing part 1 and the protective cover 22 and the patient's head more stable, while also preventing the repaired part of the patient's head from being subjected to friction.

[0045] like Figure 10 、 Figure 11 and Figure 12 As shown, it also includes a limiting mechanism, which is arranged at the rear lower part of the fixing member 1. The limiting mechanism is used to limit the patient's head. The limiting mechanism includes a second fixing block 4, which is fixed to the rear lower part of the fixing member 1. The lower part of the second fixing block 4 is rotatably connected to the first rotating member 41. The lower part of the first rotating member 41 is fixed to a limiting sleeve 42. The front and rear sides of the limiting sleeve 42 are both provided with limiting grooves 43. A rotating column 44 is rotatably connected in the limiting sleeve 42. The front and rear sides of the rotating column 44 are both fixed with protrusions 45. The protrusions 45 are slidably connected to the adjacent limiting grooves 43. The lower part of the rotating column 44 is fixed with a second rotating member 46. The lower part of the second rotating member 46 is provided with a clamping assembly. The clamping assembly is used to further limit the second rotating member 46.

[0046] like Figure 11 and Figure 12As shown, the clamping assembly includes a third fixed block 47, which is rotatably connected to the lower part of the second rotating member 46. The front part of the third fixed block 47 is fixedly connected to a connecting plate 48, and the left and right sides of the connecting plate 48 are rotatably connected to clamping members 49. Torsion springs 410 are wound between the upper and lower sides of the rear part of the clamping member 49 and the connecting plate 48. The torsion springs 410 are all wound around the corresponding clamping members 49, and the front upper part of the first rotating member 41 is fixedly connected to a limit block 411.

[0047] Because it is inconvenient for the patient's head to rotate greatly, it is necessary to limit the rotation range of the patient's head. After wearing the fixing part 1, the clamping parts 49 are rotated and opened to the side in the direction away from each other by hand, so that the torsion spring 410 is twisted, and the patient places the two clamping parts 49 on the left and right sides of the patient's neck respectively, and then releases the clamping parts 49. Under the action of the torsion spring 410, the clamping parts 49 are rotated and restored to the side in the direction of approaching each other, and the clamping parts 49 can be clamped on the patient's neck. The limit block 411 here is to prevent the patient from shaking his head too much. Then, when the patient rotates his head by shaking his head, the fixing part 1, the second fixing block 4 and the first rotating part 41 will also When the patient's neck rotates together, the limiting sleeve 42 will also rotate under the drive of the first rotating member 41. Since the patient's neck will not drive the clamping member 49 to rotate, the connecting plate 48, the third fixing block 47, the second fixing block 4, the rotating column 44 and the protrusion 45 will not rotate. When the limiting sleeve 42 rotates to the end of the limiting groove 43 and contacts the protrusion 45, the patient will feel a sudden jam and then will not continue to rotate the head spontaneously. The locking effect of the protrusion 45 and the limiting groove 43 reminds the patient not to rotate the head significantly, avoiding relative rotation between the fixing member 1 and the head, which is beneficial to prevent the protective plate 210 from rubbing against the repair part, and is also beneficial to the titanium mesh repair of the drilled hole.

[0048] like Figure 13 and Figure 14 As shown, a protection mechanism is also included, which is arranged in the front of the protective plate 210 and is used to buffer the impact force. The protection mechanism includes an airbag 5, which is fixed to the front of the protective plate 210. The left part of the first fixed block 26 is fixed with an air cylinder 51, and a piston member 52 is slidably connected in the air cylinder 51. The piston member 52 is squeezed and fitted with the protective cover 22. A fourth spring 53 is wound between the rear part of the piston member 52 and the air cylinder 51. The fourth spring 53 is wound on the piston member 52. An air pipe 54 is connected between the air cylinder 51 and the airbag 5.

[0049] When the protective cover 22 moves forward, the fixing member 1 does not move, so the air cylinder 51, the piston member 52, the fourth spring 53 and the airbag 5 do not move. The protective cover 22 will squeeze the piston member 52, causing the piston member 52 to move forward. The fourth spring 53 is compressed, and the piston member 52 squeezes the gas in the air cylinder 51 into the trachea 54. The gas enters the airbag 5 through the trachea 54, so that the airbag 5 can expand, further cushioning the impact force on the repaired part of the patient's head and avoiding the repaired part from being impacted. At the same time, the expansion of the airbag 5 can further fill the gap between the repaired part of the patient's head and the protective plate 210, making the two fit more closely, avoiding misalignment between the repaired part of the patient's head and the protective plate 210. When the protective cover moves backward and resets, under the action of the fourth spring 53, the piston member 52 moves backward and resets. At this time, the air cylinder 51 is in a negative pressure state, so the gas in the airbag 5 will flow back to the air cylinder 51 through the trachea 54, thereby balancing the negative pressure state in the air cylinder 51. The piston member 52 is squeezed by the fixing member 1, so that the piston member 52 injects the gas in the air cylinder 51 into the airbag 5, thereby expanding the airbag 5, which can not only cushion the impact force on the repaired part of the patient's head, but also further fill the gap between the repaired part of the patient's head and the protective plate 210, so that the two fit more closely, avoiding misalignment between the repaired part of the patient's head and the protective plate 210, which is beneficial to avoid friction on the repaired part.

[0050] like Figure 15 As shown, a reminder mechanism is also included. The reminder mechanism is arranged at the front upper part of the protective cover 22. The reminder mechanism is used to remind the patient that the protective cover 22 is tilted. The reminder mechanism includes a connecting seat 6. There are two connecting seats 6. The two connecting seats 6 are respectively fixed to the left and right sides of the front upper part of the protective cover 22. The connecting seats 6 are rotatably connected to a rotating connector 61, and the lower part of the rotating connector 61 is fixed to a reminder plate 62.

[0051] When the patient wears the present post-incranial surgery drilling repair device, if the patient does not wear the fixing part 1 properly, causing the protective cover 22 to tilt, the connecting seat 6 will also tilt accordingly, and the rotating connecting part 61 and the prompt plate 62 will remain vertical to the ground under the action of gravity, which makes the prompt plate 62 closer to the patient's neck, so the prompt plate 62 will contact the patient's neck. After the patient finds out, he knows that the fixing part 1 is not worn properly, so he can adjust the position of the fixing part 1 in time. After the position of the fixing part 1 is adjusted, the prompt plates 62 on both sides will not contact the patient's neck, and the patient will know that he has worn the fixing part 1 properly. The prompt plate 62 reminds the patient that the fixing part 1 is worn tilted, which is conducive to the patient wearing the fixing part 1 correctly, avoiding the protective plate 210 from sliding relative to the repair part due to the tilt of wearing, thereby avoiding the repair part from being subjected to friction.
