Abstract
Description
Technical Field
[0001] This invention relates to the field of neurosurgical medical device technology, specifically to an adjustable and breathable post-craniotomy recovery device. Background Technology
[0002] In neurological diseases, severe traumatic brain injury, intracranial hematoma, cerebral edema, and cerebral hemorrhage can all lead to increased intracranial pressure and even brain herniation, endangering life. Mechanical methods are needed to open the patient's skull for decompression. To alleviate intracranial pressure, the bone flap in the defect area cannot be immediately repositioned after surgery, and the patient requires a period of hypothermic brain protection post-operatively. Early drainage and decompression of the wound are also necessary. However, current techniques typically use gauze wrapping or a medical hood to protect the wound, but both gauze and medical hoods have the following drawbacks:
[0003] 1. The recovery period for skull wounds is generally more than three months. However, gauze and medical caps are not very protective and do not provide good protection for skull wounds. They are prone to causing secondary damage to the patient's intracranial cavity when the wound is compressed, hit or collided with external force.
[0004] 2. The heat dissipation and breathability of a medical cap depends entirely on the material used in the cap. When the wound is in poor condition, it may even be necessary to remove the cap for ventilation and heat dissipation. However, when gauze and medical cap are removed and put on, there is medication adhesion between them and the skull. When changing them, there is a pulling force, which is not conducive to the patient's wound healing and aggravates the patient's pain.
[0005] 3. Medical caps are mostly of fixed size and cannot be adapted to the size of the patient's postoperative wound. They are not very adaptable and their position on the skull is unstable when they do not fit the wound size, resulting in poor safety. Summary of the Invention
[0006] Therefore, the present invention provides an adjustable and breathable post-craniotomy recovery device to solve the problem in the prior art that the gauze and medical caps have poor protection, poor breathability, and inconvenient heat dissipation for the post-craniotomy wound, which is not conducive to the patient's wound recovery.
[0007] To achieve the above objectives, the present invention provides the following technical solution: an adjustable and breathable post-craniotomy recovery device, comprising a skull cap, an air exchange groove provided in the upper part of the skull cap, a combined transmission groove provided in the lower part of the skull cap, a power motor installed in the air exchange groove and the combined transmission groove, a heat dissipation and ventilation control mechanism installed in the air exchange groove, and a protection range adjustment mechanism installed in the combined transmission groove;
[0008] The heat dissipation and ventilation control mechanism is used to adjust the airflow of the skull cap according to the severity of the patient's skull injury, thereby controlling and adjusting the heat dissipation and ventilation of the wound.
[0009] The protection range adjustment mechanism is used to adjust the wound support area of the bottom surface of the skull cap according to the wound area of the patient's skull.
[0010] The heat dissipation and ventilation control mechanism includes a guide rail, a slide groove, a bidirectional lead screw, two sliders, two support plates, eight rotary seats, twelve locking pins, and eight limiting rods. A guide rail is fixedly installed in the middle of the ventilation slot. A slide groove is opened in the guide rail. A bidirectional lead screw is rotatably installed in the slide groove. Two sliders are slidably installed in the slide groove. Support plates are provided in the top and bottom of the ventilation slot. Rotary seats are fixedly installed on the front and rear of the left and right walls of the two support plates. Limiting rods are rotatably installed in each of the eight rotary seats through locking pins.
[0011] The protection range adjustment mechanism includes a power screw, three transverse sliding racks, three helical racks, three longitudinal mating racks, three connecting rods, three pairs of sector plates, three pairs of folding plates, a spindle, and a drive gear. The power screw is rotatably mounted in the lower part of the combined transmission groove. Three transverse sliding racks are equidistantly slidably mounted in the lower part of the combined transmission groove. Helical racks are fixedly mounted on the upper walls of each of the three transverse sliding racks. Longitudinal mating racks are meshed with the middle of the upper walls of each of the three helical racks. Connecting rods are fixedly mounted on the lower outer walls of each of the three longitudinal mating racks. Two sector plates are fixedly connected to the lower outer walls of each connecting rod. Folding plates are rotatably hinged to the outer sides of each of the six sector plates via hinges. A spindle is rotatably mounted in the middle of the combined transmission groove. A drive gear is fixedly sleeved on the upper outer wall of the spindle.
[0012] Furthermore, the aforementioned power motor is fixedly installed at the left end of the ventilation slot, and the output shaft of the power motor at the left end of the ventilation slot is fixedly connected to the left end of the bidirectional lead screw.
[0013] Furthermore, the inner walls of the sliders on the left and right sides are threadedly connected to the outer walls of the left and right sides of the bidirectional lead screw, respectively.
[0014] Furthermore, the outer ends of the four limiting rods at the front and rear are rotatably connected to the front and rear walls of the two sliders via locking pins.
[0015] Furthermore, the skull cap is made of elastic fibers.
[0016] Furthermore, the lower power motor is fixedly installed in the lower left part of the combined transmission groove, and the output end of the power motor in the lower left part of the combined transmission groove is fixedly connected to the front end of the power screw.
[0017] Furthermore, the inner wall of the transverse sliding rack at the left end is threadedly connected to the outer wall of the power screw.
[0018] Furthermore, all three longitudinally mating racks are slidably connected to the upper part of the combined transmission groove, and the three pairs of sector plates are equidistantly slidably connected to the outside of the combined transmission groove.
[0019] Furthermore, the outer wall of the drive gear meshes with the inner walls of the three transverse sliding racks.
[0020] The present invention has the following advantages:
[0021] I. This invention, by installing a protection range adjustment mechanism within the combined transmission groove, allows medical personnel to adjust the size of the patient's skull wound before use of the skull cap. The lower power motor is activated, causing the power screw to rotate. When the power screw rotates clockwise, it engages with the left transverse sliding rack, causing it to slide left within the lower part of the combined transmission groove. The left transverse sliding rack meshes with the drive gear, which rotates clockwise and meshes with the other two transverse sliding racks, allowing all three transverse sliding racks to slide clockwise within the lower part of the combined transmission groove. The three oblique racks mesh with the three longitudinally cooperating racks, causing them to slide from the inside out in the upper part of the combined transmission groove. Under the fixed connection of the connecting rod, the three pairs of sector plates can slide outwards from the inside in the lower part of the combined transmission groove. Once the outer diameter of the three pairs of sector plates combined with the skull cap is larger than the patient's wound area, the lower power motor is stopped. The three pairs of folding plates are then rotated open, allowing the three pairs of sector plates to slide outwards. The plate and three pairs of folding plates form a circle, which can be combined with the skull cap to form a support frame of different sizes for the skull affected area. This supports and protects the skull affected area. The support frame can be used for wounds of different sizes, making it highly adaptable. When in use, the support frame can perfectly fit the outer edge of the wound. The support frame has high stability on the skull and good safety. The lower part of the skull cap is provided with an arc groove, which allows the support frame to support the affected area without pressing on it. It has high protection and good protection effect on the skull wound, avoiding secondary damage to the patient's intracranial cavity caused by external force or collision. It solves the problems of poor protection of gauze and medical caps in existing technologies, poor protection effect on skull wounds, easy to cause secondary damage to the patient's intracranial cavity when the area is stuck, external force or collision, and the fixed size of medical caps. They cannot be changed according to the size of the patient's postoperative wound, resulting in poor applicability. In addition, when the size of the cap does not match the size of the wound, the stability of the cap on the skull is low, resulting in poor safety.
[0022] II. This invention, by installing a heat dissipation and ventilation control mechanism within the ventilation slot, allows for a more efficient and controlled ventilation of the skull cap compared to existing technologies. When the ventilation needs to be increased or decreased at the patient's skull injury site, the upper power motor rotates clockwise or counterclockwise, driving a bidirectional lead screw. This lead screw, connected to two sliders via threaded transmission, enables the two sliders to slide synchronously towards the center or to the left and right ends within the groove. Under the linkage of the sliders and the limiting rod, the two support plates can simultaneously expand or contract the ventilation slot outwards or inwards, increasing or decreasing the ventilation of the skull cap. This eliminates the need for repeated disassembly and reassembly of the skull cap, meeting the ventilation and heat dissipation needs of the patient's skull injury site. This promotes wound healing, reduces patient suffering, and solves the problem that the ventilation of existing medical caps depends entirely on the material used, such as gauze or medical caps, which hinders wound healing and exacerbates patient suffering.

[0037] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.
[0038] Example 1
[0039] Refer to the instruction manual appendix Figure 1-8 This embodiment provides an adjustable and breathable post-craniotomy recovery device, including a skull cap 1, a combined transmission groove 3 provided in the lower part of the skull cap 1, a power motor 4 installed in the combined transmission groove 3, and a protection range adjustment mechanism 6 installed in the combined transmission groove 3.
[0040] Among them, such as Figure 1-8As shown, the protection range adjustment mechanism 6 is used to adjust the wound support area of the bottom surface of the skull cap according to the wound area of the patient's skull. The protection range adjustment mechanism 6 includes a power screw 7, three transverse sliding racks 8, three oblique racks 9, three longitudinal mating racks 10, three connecting rods 11, three pairs of sector plates 12, three pairs of folding plates 13, a spindle 14, and a drive gear 15. The combined transmission groove 3 A power screw 7 is rotatably mounted in the lower part of the combined transmission groove 3. Three transverse sliding racks 8 are equidistantly slidably mounted in the lower part of the combined transmission groove 3. An oblique rack 9 is fixedly mounted on the upper wall of each of the three transverse sliding racks 8. A longitudinally engaging rack 10 is meshed with the middle of the upper wall of each of the three oblique racks 9. A connecting rod 11 is fixedly mounted on the lower outer wall of each of the three longitudinally engaging racks 10. Two sector plates 12 are fixedly connected to the lower outer wall of each of the connecting rods 11. A folding plate 13 is hinged to the outer side of each of the six sector plates 12. A spindle 14 is rotatably mounted in the middle of the combined transmission groove 3. A drive gear 15 is fixedly sleeved on the upper outer wall of the spindle 14.
[0041] The aforementioned protection range adjustment mechanism 6 consists of a power screw 7, three transverse sliding racks 8, three helical racks 9, three longitudinally engaging racks 10, three connecting rods 11, three pairs of sector plates 12, three pairs of folding plates 13, a spindle 14, and a drive gear 15. This protection range adjustment mechanism 6 is used to adjust the wound support area of the skull cap's bottom surface according to the wound area of the patient's skull. Before using the skull cap 1, medical personnel can start the lower power motor 4 according to the size of the patient's skull wound, causing the power screw 7 to rotate in conjunction. When the power screw 7 rotates clockwise, it engages with the left transverse sliding rack 8 via a threaded transmission, causing the left transverse sliding rack 8 to slide to the left within the lower part of the combined transmission groove 3. The left transverse sliding rack 8 meshes with the drive gear 15. The drive gear 15 rotates clockwise and meshes with the other two transverse sliding racks 8, causing the three transverse sliding racks 8 to slide clockwise within the lower part of the combined transmission groove 3. The three helical racks 9... The linkage engages with three longitudinally cooperating racks 10, which slide from the inside to the outside on the upper part of the combined transmission groove 3. Under the fixed connection of the connecting rod 11, the three pairs of sector plates 12 can slide and extend outward from the inside to the outside on the lower part of the combined transmission groove 3. When the outer diameter circle area of the three pairs of sector plates 12 and the skull cap 1 is larger than the area of the patient's wound, the transmission of the lower power motor 4 is stopped. Then, the three pairs of folding plates 13 are rotated and opened, so that the three pairs of sector plates 12 and the three pairs of folding plates 13 form a circle. The circle can be combined with the skull cap 1 to form a support frame for the skull affected area, providing support and protection for the skull affected area. The support frame can be used for wounds of different sizes, has strong applicability, and can perfectly fit the outer periphery of the wound when in use. The support frame has high stability in position on the skull and is safe to use. The skull cap 1 has a circular groove in the lower part, which allows the support frame to support the affected area without pressing on it. It has high protection and a good protective effect on skull wounds, avoiding secondary damage to the patient's intracranial cavity caused by external force or collision. This embodiment specifically solves the problems in the prior art where the recovery period for skull wounds is generally more than three months, but the gauze and medical caps have poor protection and a poor protective effect on skull wounds. They are prone to secondary damage to the patient's intracranial cavity when the wound is compressed, hit or collided with external force. The size of medical caps is mostly fixed and cannot be changed according to the size of the wound after surgery, resulting in poor applicability. In addition, when the cap is not compatible with the size of the wound, the stability of the cap on the skull is low, resulting in poor safety.
[0042] More comprehensively, such as Figure 1-3 As shown, the skull cap 1 is made of elastic fibers, which allows the skull cap 1 to support the affected area of the patient's skull while also facilitating ventilation and heat dissipation in the affected area.
[0043] More comprehensively, such as Figure 4-8As shown, the lower power motor 4 is fixedly installed in the lower left part of the combined transmission groove 3, and the output end of the power motor 4 in the lower left part of the combined transmission groove 3 is fixedly connected to the front end of the power screw 7, so that starting the lower power motor 4 can drive the power screw 7 to rotate, thereby providing power for the transmission of the protection range adjustment mechanism 6.
[0044] More comprehensively, such as Figure 4-6 As shown, the inner wall of the left-end transverse sliding rack 8 is threadedly connected to the outer wall of the power screw 7, so that when the power screw 7 rotates, it can be threadedly driven with the left-end transverse sliding rack 8, thereby driving the left-end transverse sliding rack 8 to move in tandem.
[0045] More comprehensively, such as Figure 4-6 As shown, the three longitudinally mating racks 10 are slidably connected to the upper part of the combined transmission groove 3, and the three pairs of sector plates 12 are equidistantly slidably connected to the outside of the combined transmission groove 3. The combined transmission groove 3 can restrict the movement path of the three longitudinally mating racks 10 and the three pairs of sector plates 12.
[0046] More comprehensively, such as Figure 5-6 As shown, the outer wall of the drive gear 15 meshes with the inner wall of the three transverse sliding racks 8, so that the left transverse sliding rack 8 can mesh with the drive gear 15 for transmission when moving left and right. The drive gear 15 can mesh with the other two transverse sliding racks 8 for transmission, so that the three transverse sliding racks 8 are linked together.
[0047] Example 2
[0048] Refer to the instruction manual appendix Figure 1-3 and Figure 9-11 This embodiment provides an adjustable and breathable post-craniotomy recovery device, a heat dissipation and breathability control mechanism 5, an air exchange groove 2 is provided in the upper part of the skull cap 1, a power motor 4 is installed in the air exchange groove 2, and the heat dissipation and breathability control mechanism 5 is installed in the air exchange groove 2.
[0049] Among them, such as Figure 9-11As shown, the heat dissipation and ventilation control mechanism 5 is used to adjust the airflow of the skull cap according to the severity of the patient's skull injury, thereby controlling and adjusting the heat dissipation and ventilation of the wound. The heat dissipation and ventilation control mechanism 5 includes a guide rail 16, a slide groove 17, a bidirectional screw 18, two sliders 19, two support plates 20, eight rotating seats 21, twelve locking pins 22, and eight limiting rods 23. The guide rail 16 is fixedly installed in the middle of the ventilation channel 2. The guide rail 16 is provided in the slide groove 17. The bidirectional screw 18 is rotatably installed in the slide groove 17. Two sliders 19 are slidably installed in the slide groove 17. Support plates 20 are provided in the top and bottom of the ventilation channel 2. Rotating seats 21 are fixedly installed on the front and rear parts of the left and right walls of the two support plates 20. Limiting rods 23 are rotatably installed in each of the eight rotating seats 21 through locking pins 22.
[0050] The aforementioned heat dissipation and ventilation control mechanism 5 consists of a guide rail 16, a slide groove 17, a bidirectional lead screw 18, two sliders 19, two support plates 20, eight rotating seats 21, twelve locking pins 22, and eight limiting rods 23. This mechanism 5 is used to adjust the airflow of the skull cap according to the severity of the patient's skull injury, thereby controlling the heat dissipation and ventilation of the wound. When the ventilation needs to be increased or decreased at the site of the patient's skull injury, the output end of the upper power motor 4 rotates clockwise or counterclockwise, which drives the bidirectional lead screw 18 in conjunction. The bidirectional lead screw 18 is threadedly driven by the two sliders 19, causing the two sliders 19 to move synchronously towards the center or to the left and right ends within the slide groove 17. Under the linkage of slider 19 and limit rod 23, the two support plates 20 can move outward or inward simultaneously to expand or shrink the ventilation slot 2, thereby increasing or decreasing the ventilation of the skull cap. This eliminates the need for repeated disassembly and reassembly of the skull cap, meeting the ventilation and heat dissipation needs of the patient's skull, which is beneficial for wound recovery and reduces the patient's pain. This implementation method specifically solves the problem that the heat dissipation and ventilation of medical caps in the prior art depend entirely on the material used for the cap. When the wound is in poor condition, it may even be necessary to remove the cap for ventilation and heat dissipation. However, there is drug adhesion between the gauze and the skull when the medical cap is disassembled and reassembled, and the pulling force is generated when it is replaced, which is not conducive to the patient's wound recovery and aggravates the patient's pain.
[0051] More comprehensively, such as Figure 9 As shown, the upper power motor 4 is fixedly installed at the left end of the ventilation slot 2, and the output shaft of the power motor 4 at the left end of the ventilation slot 2 is fixedly connected to the left end of the bidirectional lead screw 18. Activating the upper power motor 4 can drive the bidirectional lead screw 18 to rotate in linkage, providing power for the heat dissipation and ventilation control mechanism 5.
[0052] More comprehensively, such as Figure 9-11As shown, the inner walls of the left and right sliders 19 are threadedly connected to the outer walls of the left and right sides of the bidirectional lead screw 18, respectively, so that the rotation of the bidirectional lead screw 18 can drive the two sliders 19 through the threaded transmission, causing the two sliders 19 to slide relative to each other in the groove 17.
[0053] More comprehensively, such as Figure 9-11 As shown, the outer ends of the four limiting rods 23 at the front and rear are rotatably connected to the front and rear walls of the two sliders 19 through locking pins 22, so that the two sliders 19 can move up and down in conjunction with the two support plates 20 under the linkage of the limiting rods 23.
[0054] In summary:
[0055] III. In this invention, a protection range adjustment mechanism 6 is installed within the combined transmission groove 3. Before the skull cap 1 is used, medical personnel can start the lower power motor 4 according to the size of the patient's skull wound, causing the power screw 7 to rotate in conjunction. When the power screw 7 rotates clockwise, it engages with the left transverse sliding rack 8 via a threaded transmission, causing the left transverse sliding rack 8 to slide to the left within the lower part of the combined transmission groove 3. The left transverse sliding rack 8 meshes with the drive gear 15, and the drive gear 15 rotates clockwise to mesh with the other two transverse sliding racks 8. The movement causes the three transverse sliding racks 8 to slide clockwise within the lower part of the combined transmission groove 3. The three oblique racks 9, in conjunction with the three longitudinally cooperating racks 10, engage and transmit power, driving the three longitudinally cooperating racks 10 to slide from the inside out in the upper part of the combined transmission groove 3. Under the fixed connection of the connecting rod 11, the three pairs of sector plates 12 can slide outwards from the inside to the outside in the lower part of the combined transmission groove 3. Once the outer diameter of the three pairs of sector plates 12 combined with the skull cap 1 is larger than the area of the patient's wound, the lower power motor 4 stops transmitting power, and then the three pairs of folding plates are... 13. When rotated open, three pairs of fan-shaped plates 12 and three pairs of folding plates 13 form a circle. This circle can be combined with the skull cap 1 to form a skull support frame, providing support and protection for the skull wound. The support frame can be used for wounds of different sizes, offering strong applicability. Furthermore, the support frame perfectly adapts to the outer edge of the wound during use, exhibiting high stability in its position on the skull and good safety. The lower part of the skull cap 1 has an arc groove, allowing the support frame to provide support to the wound without pressing on it, resulting in high protection for skull wounds. It offers excellent protection, preventing secondary damage to the patient's intracranial cavity caused by external impacts or collisions. It addresses the shortcomings of existing technologies, such as poor protection of gauze and medical caps for skull wounds, which can easily cause secondary damage to the patient's intracranial cavity when pressure, external impacts, or collisions occur at this site. Furthermore, the fixed size and specifications of medical caps cannot be adapted to the size of the postoperative wound, resulting in poor applicability. Additionally, when the cap is not properly matched to the wound area, the stability of the cap's position on the skull is low, leading to poor safety during use.
[0056] IV. This invention utilizes a heat dissipation and ventilation control mechanism 5 installed within the ventilation slot 2. When the ventilation volume at the patient's skull injury site needs to be increased or decreased, the output end of the upper power motor 4 rotates clockwise or counterclockwise, which drives the bidirectional lead screw 18 in linkage. The bidirectional lead screw 18 is threadedly driven by two sliders 19, which can drive the two sliders 19 to slide synchronously towards the center or to the left and right ends within the slide groove 17. Under the linkage action of the sliders 19 and the limiting rod 23, the two support plates 20 can synchronously move outward or inward, expanding or shrinking the ventilation slot 2, thereby increasing or decreasing the ventilation volume of the skull cap. This eliminates the need for repeated disassembly and reassembly of the skull cap, meeting the ventilation and heat dissipation needs of the patient's skull injury site, which is beneficial for wound recovery and reduces patient pain. This solves the problem that the heat dissipation and ventilation volume of existing medical caps depends entirely on the material used in the cap. The disassembly and reassembly of gauze and medical caps for heat dissipation are not only detrimental to wound recovery but also aggravate patient pain.
[0057] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
