Description

Technical Field

[0001] This invention relates to the field of medical assistive device technology, specifically to a soft-head frame fixation device for neurosurgery. Background Technology

[0002] Neurosurgery is known for its precision and complexity, and its success depends heavily on the accurate and stable fixation of the patient's head during the procedure. An ideal head fixation device must not only provide the surgeon with an absolutely stable and undisturbed surgical field to ensure the accuracy of the operation, but also take into account the patient's comfort and safety, minimizing complications caused by the fixation itself, such as scalp pressure injury, nerve and blood vessel compression, or postoperative neck discomfort.

[0003] Currently, clinical head fixation is mainly achieved through head frames, such as the Mayfield® head frame manufactured by Medtronic. The core component of this device includes a U-shaped head frame, the spacing between the two sides of which can be dynamically adjusted and locked, and several head pins on the U-shaped head frame. By adjusting the spacing between the two sides of the U-shaped head frame, it can be adapted to patients with different head sizes, and the head pins are inserted into the patient's head to achieve the function of fixing the patient's head.

[0004] However, when such devices are used to fix the patient's head, the patient's neck and head remain suspended in the air. Medical staff must support the patient's head with their hands, or the patient must exert force themselves, to align the head with the head pin. If the patient's head shifts or slides during clamping, fixation will fail, severely impacting surgical efficiency. Therefore, the fundamental flaw of existing technology is the difficulty in providing adaptive support to the patient's head based on its size while clamping it, leading to difficult fixation and low surgical efficiency. Therefore, this invention provides a soft head frame fixation device for neurosurgery to solve the above problems. Summary of the Invention

[0005] To address the aforementioned issues, this invention provides a soft-head fixation device for neurosurgery. Through the design of the adjustment plate and support rod, the device can not only clamp the patient's head but also provide adaptive support according to the size of the patient's head. This eliminates the need for medical staff to lift the head or for the patient to exert force, effectively ensuring the stability of the patient's head, thereby reducing the difficulty of the fixation operation and improving surgical efficiency.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A soft-head frame fixation device for neurosurgery includes a hospital bed and an adjustment frame. A mounting plate is detachably connected to the bottom of the hospital bed. An adjustment groove is opened at the top of the adjustment frame, and adjustment plates are symmetrically slidably fitted within the adjustment groove. Each adjustment plate is equipped with a clamping component for rigidly clamping both sides of the patient's head. A spacing adjustment component is provided inside the adjustment frame for driving the adjustment plates closer together and further apart. A piston box is fixedly connected to the top of the adjustment frame, and a support rod is vertically slidably fitted within the piston box. A support plate is fixedly connected to the top of the support rod, and an airbag is fixedly connected to the support plate. A sliding component is provided inside the piston box for driving the support rod to slide vertically along the piston box. A driving component is provided outside the adjustment frame for driving the spacing adjustment component and the sliding component to operate synchronously. An angle adjustment component is provided at the bottom of the adjustment frame for adjusting the angle of the adjustment frame, and a height adjustment component is provided at the bottom of the mounting plate for adjusting the height of the adjustment frame.

[0007] The technical principle of the above solution is as follows:

[0008] The patient lies supine on the bed with their head placed on the airbag. The drive assembly synchronizes the spacing adjustment assembly and the sliding assembly. The spacing adjustment assembly drives the adjustment plate to slide laterally within the adjustment slot, bringing the plates closer together. The adjustment plates then move the clamping assemblies closer together, thus clamping and fixing the patient's head. Simultaneously, the sliding assembly drives the support rod to slide upward along the piston box, pushing the support plate and airbag upward. The airbag lifts the patient's head and aligns it with the clamping assemblies. During this process, the clamping assemblies on both sides of the patient's head and the airbag below the patient's head move closer together, gradually reducing the clamping space and working together to support and fix the patient's head.

[0009] The above approach has the following beneficial effects:

[0010] 1. In actual surgical procedures, although existing devices can fix the patient's head, the lack of support for the area below the head and neck leaves the head and neck completely suspended. During prolonged surgery, this can lead to postoperative discomfort or strain on the neck muscles and ligaments. This invention, through the design of a support rod, can continuously support heads of different sizes, reducing discomfort and strain on the patient's neck muscles and ligaments. Furthermore, the support point is located below the head, and the support range is small, so it will not obstruct the skull or the area above the head, thus ensuring the proper conduct of the surgery.

[0011] 2. In existing technologies, while simple head pin fixation can ensure stability, it causes significant trauma to the patient's head. Even with local anesthesia, there is still a clear risk of pin holes, pain, and bleeding after pin removal. While simple flexible support is comfortable and non-invasive, it cannot guarantee surgical stability. This invention fully considers the head structure. The sides of the head are more elastic than the forehead and back of the head, making them suitable for withstanding rigid fixation. Therefore, this invention ensures the stability of the patient's head by rigidly clamping the sides of the head, while simultaneously improving the stability of the patient's head by providing flexible support to the forehead or back of the head. This effectively reduces pressure on the patient's head and improves patient comfort while ensuring the stability of head fixation.

[0012] 3. This invention enables the device to clamp patients with heads of different sizes by quickly adjusting the spacing between the adjustment plates. In addition, the device can drive the support rod to move vertically along the piston box while adjusting the spacing between the adjustment plates, so that the support height of the device matches the clamping spacing. The two are dynamically coordinated, so that the device can automatically maintain the appropriate size of clamping and support for the patient's head according to the size of the head, without the need for medical staff intervention or the patient to exert force. This effectively reduces the difficulty of fixation, ensures the stability of fixation, and improves surgical efficiency.

[0013] Furthermore, the clamping assembly includes a connecting rod fixedly connected to the side wall of the adjustment plate, and a clamping block is fixedly connected to the side of the connecting rod away from the adjustment plate.

[0014] Beneficial effects: When the adjustment plates move closer to each other, they will cause the connecting rod and the clamping block to move closer to each other, thereby making the clamping block fit against the sides of the patient's head and fixing the head.

[0015] Furthermore, the spacing adjustment component includes a gear that rotates and engages with the inner wall of the adjustment frame, with an upper rack and a lower rack meshing above and below the gear, respectively, and both the upper rack and the lower rack being laterally slidably connected to the inner wall of the adjustment frame.

[0016] Beneficial effects: Since the upper and lower racks mesh with the gear above and below respectively, when the gear rotates, the gear will drive the upper and lower racks to move away from or towards each other, thereby causing the adjusting plate, connecting rod and clamping block to move away from or towards each other, thus achieving adaptive clamping for heads of different sizes.

[0017] Furthermore, the sliding assembly includes a piston plate fixedly connected to the bottom of the support rod, and the piston plate slides vertically with the inner wall of the piston box; the two sides of the adjusting frame are respectively provided with a first air supply assembly for driving the piston plate to slide vertically along the inner wall of the piston box and a second air supply assembly for supplying air to the airbag.

[0018] Beneficial effects: When the piston plate slides vertically along the piston box, the piston plate will push the support rod, support plate and airbag to slide vertically, thereby supporting heads of different sizes. At the same time, the airbag will inflate and expand, thereby providing flexible support for the patient's head and improving the patient's comfort.

[0019] Furthermore, the first air supply assembly includes a first air supply box fixedly connected to one side of the adjustment frame, a first air supply plate slidably fitted inside the first air supply box, a first air supply rod fixedly connected to the side of the lower rack near the first air supply box, the first air supply rod extending into the first air supply box and fixedly connected to the first air supply plate; a first vent hole is opened on the side of the first air supply box away from the adjustment frame; the top of the first air supply box communicates with the piston box.

[0020] Beneficial effects: When the gear drives the lower rack to move, the lower rack will drive the first air supply rod and the first air supply plate to slide laterally along the inner wall of the first air supply box, thereby delivering gas to the piston box and driving the piston plate to move upward to achieve head support.

[0021] Furthermore, the second air supply assembly includes a second air supply box fixedly connected to the other side of the adjustment frame, a second air supply plate slidably fitted inside the second air supply box, a second air supply rod fixedly connected to the side of the upper rack near the second air supply box, the second air supply rod extending into the second air supply box and fixedly connected to the second air supply plate; a second vent is opened on the side of the second air supply box away from the adjustment frame; the top of the second air supply box communicates with the side wall of the airbag.

[0022] Beneficial effects: When the gear drives the upper rack to move, the upper rack will drive the second air supply rod and the second air supply plate to slide laterally along the inner wall of the second air supply box, thereby delivering gas to the airbag, causing the airbag to inflate and expand, thus providing flexible support for the head.

[0023] Furthermore, the drive assembly includes a controller and a first drive unit embedded in the side wall of the adjustment frame. The output shaft of the first drive unit is coaxially and fixedly connected to the gear. Several image recognizers (not shown in the figure) are installed on the adjustment plate. The image recognizers are used to acquire images of the patient's head and transmit them to the controller. The side wall of the piston box is connected to a pump assembly. The controller is used to control the operation of the first drive unit and the pump assembly according to the images of the patient's head.

[0024] Beneficial effects: The controller drives the first drive component to operate based on the patient's head image, which can realize dynamic fixation and adaptive support of the head, effectively improving the automation level of the device and the convenience of fixation operation.

[0025] Furthermore, the angle adjustment component includes a support column, a second drive component is fixedly connected to the top of the support column, the output shaft of the second drive component is fixedly connected to the bottom of the adjustment frame, and a controller is used to control the operation of the second drive component; a bending frame is rotatably connected to the bottom of the support column, and a pitch adjustment component for driving the support column to rotate around the bending frame is provided on the bending frame.

[0026] Beneficial effects: When the second drive unit is activated by the controller, the output shaft of the second drive unit will drive the adjustment frame to rotate around the output shaft axis, thereby adjusting the angle of the adjustment frame and causing the patient's head to swing, making it easier for doctors to perform surgical operations at different angles.

[0027] Furthermore, the pitch adjustment assembly includes a third drive unit embedded in the side wall of the bending frame, the output shaft of the third drive unit being fixedly connected to the bottom of the support column, and a controller for controlling the operation of the third drive unit.

[0028] Beneficial effects: When the third drive unit is activated by the controller, the output shaft of the third drive unit will drive the support column to swing radially around the bending frame, thereby adjusting the pitch position of the adjustment frame, which in turn causes the patient's head to tilt backward or forward, making it easier to adjust the patient's pitch posture.

[0029] Furthermore, the height adjustment assembly includes an electric cylinder fixedly connected to the bottom of the mounting plate, with the output shaft of the electric cylinder fixedly connected to the top of the bending frame; a controller is used to control the operation of the electric cylinder.

[0030] Beneficial effects: By controlling the operation of the electric cylinder through the controller, the height of the bending frame, support column and adjustment frame can be adjusted, thereby adjusting the height of the airbag, clamping block and patient's head, improving the adaptability of the device.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] The following detailed description illustrates the specific implementation method:

[0043] Example 1:

[0044] like Figure 1 and Figure 7As shown, a soft-head frame fixation device for neurosurgery includes a bed 22 and an adjustment frame 8, with an adjustment groove on the top of the adjustment frame 8. A piston box 14 is welded to the top of the adjustment frame 8, and a support rod 25 is vertically slidably fitted inside the piston box 14. A support plate 21 is welded to the top of the support rod 25, and an airbag 15 is fixedly adhered to the support plate 21.

[0045] like Figure 2 and Figure 3 As shown, symmetrical sliding adjustment plates 10 are fitted within the adjustment groove. Each adjustment plate 10 is equipped with a clamping assembly for rigidly clamping both sides of the patient's head. The clamping assembly includes a connecting rod 11 bolted to the side wall of the adjustment plate 10. A clamping block 12 is fixedly bonded to the side of the connecting rod 11 away from the adjustment plate 10 (in this embodiment, the clamping block 12 is made of hard rubber, which has a high coefficient of friction and can work with the airbag 15 to fix the patient, meeting the need for fixing the patient's head without causing trauma to the patient's head). A spacing adjustment assembly is provided within the adjustment frame 8 to drive the adjustment plates 10 closer together and further apart. The spacing adjustment assembly includes a gear 16 rotatably fitted to the inner side wall of the adjustment frame 8. An upper rack 17 and a lower rack 18 mesh above and below the gear 16, respectively, and both the upper rack 17 and the lower rack 18 are laterally slidably connected to the inner side wall of the adjustment frame 8. A drive assembly is provided outside the adjustment frame 8 to drive the gear 16 to rotate. The drive assembly includes a controller and a first drive unit 13 (in this embodiment, the first drive unit 13 is an AC motor) embedded in the side wall of the adjustment frame 8. The output shaft of the first drive unit 13 is coaxially keyed with the gear 16. The controller is connected to the first drive unit 13 via an electrical signal. Several image recognizers (not shown in the figure) are installed on the adjustment plate 10. The controller is used to control the operation of the first drive unit 13 according to the patient's head image.

[0046] Specifically, such as Figure 6 As shown, in the initial state, the distance between the adjustment plates 10 is the largest, and the clamping space of the device (the space to accommodate the head) is also the largest. The patient lies on the bed 22 in one of the following positions: supine, lateral, or prone, depending on the needs of the surgery. This embodiment will be described using the supine position as an example.

[0047] like Figure 3As shown, the back of the patient's head rests on the top of the airbag 15. Initially, the clamping blocks 12 are located on the upper sides of the patient's head. When the head is initially fixed, the image recognition device acquires an image of the patient's head. The controller analyzes the width of the patient's head based on the image and then activates the first drive unit 13. The output shaft of the first drive unit 13 drives the gear 16 to rotate clockwise. Since the upper rack 17 and the lower rack 18 mesh with the gear 16 above and below, respectively, the gear 16 drives the upper rack 17 to move to the right and the lower rack 18 to move to the left. This causes the adjusting plate 10 to move the connecting rod 11 and the clamping blocks 12 closer together, gradually reducing the clamping space, so that the clamping blocks 12 gradually press against the sides of the patient's head (e.g., ...). Figure 5 As shown in the figure, adaptive clamping is achieved to keep the patient's head stable. Compared with the existing clamping method that moves only one side, this embodiment uses the synchronous and symmetrical movement of the two adjustment plates 10 to keep the patient's head in a central position and to distribute the force evenly on both sides of the head, thereby improving the patient's treatment comfort. At the same time, the synchronous movement of the two adjustment plates 10 effectively shortens the adjustment time compared with unilateral adjustment, thus improving the operation efficiency.

[0048] like Figure 3 and Figure 4 As shown, the piston box 14 is equipped with a sliding assembly for driving the support rod 25 to slide vertically along the piston box 14; the sliding assembly includes a piston plate 26 bolted to the bottom of the support rod 25, and the piston plate 26 slides vertically with the inner wall of the piston box 14; the right side of the adjusting frame 8 is equipped with a first air supply assembly for driving the piston plate 26 to slide vertically along the inner wall of the piston box 14. The first air supply assembly includes a first air supply box 9 bolted to the right side of the adjusting frame 8, a first air supply plate 20 slidingly fitted inside the first air supply box 9, a first air supply rod 19 bolted to the side of the lower rack 18 near the first air supply box 9, the first air supply rod 19 extending into the first air supply box 9 and bolted to the first air supply plate 20; a first vent hole is opened on the side of the first air supply box 9 away from the adjusting frame 8 (the first vent hole can ensure that the first air supply box 9 is connected to the outside and ensure that the first air supply plate 20 moves smoothly); the top of the first air supply box 9 is connected to the piston box 14. The piston box 14 has a pump assembly (in this embodiment, the pump assembly is a bidirectional air pump 27) connected to its side wall, and the controller is used to control the operation of the bidirectional air pump 27 according to the patient's head image.

[0049] Specifically, such as Figure 3 and Figure 4As shown, during the process of the lower rack 18 moving to the left driven by the gear 16, the lower rack 18 will drive the first air supply rod 19 and the first air supply plate 20 to move to the left, thereby delivering the gas in the first air supply box 9 to the piston box 14. This causes the piston plate 26 to slide upward along the inner wall of the piston box 14, thereby pushing the support rod 25, the support plate 21, and the airbag 15 upward. The airbag 15 will move the patient's head upward, continuously supporting the patient's head, facilitating subsequent stable clamping of the patient's head without the need for medical staff to lift it or for the patient to exert force on their own. At the same time, during the process of raising the patient's head, the clamping points on both sides of the head will also align with the clamping blocks 12, so that when the clamping blocks 12 are close to the sides of the patient's head, they can reasonably fix the clamping points on both sides of the patient's head, so that the height of the patient's head matches the clamping position of the clamping blocks 12, automatically achieving a stable and reasonable head fixation operation.

[0050] During the adjustment process, when the gas supply in the first gas supply box 9 is about to be exhausted, the image recognition device will capture an image of the patient's head. The controller will determine whether the patient's head has reached the target height based on the image and whether the clamping point is aligned with the clamping block 12. If the clamping point is lower than the clamping block 12, the controller will start the bidirectional air pump 27 to replenish gas into the piston box 14. If the clamping point is higher than the clamping block 12, the controller will start the bidirectional air pump 27 to discharge some of the gas from the piston box 14, thereby achieving a fine adjustment of the patient's head height and ultimately fixing the clamping point of the clamping block 12 to the patient's head.

[0051] The bidirectional air pump 27 generates noise and vibration during operation, which can affect the fixation of the patient's head and the patient's medical experience. Compared to adjusting the head height solely through the bidirectional air pump 27, this embodiment uses a method that first performs a large-scale adjustment via mechanical transmission, followed by a fine-tuning using the bidirectional air pump 27. This significantly reduces the operating time of the bidirectional air pump 27, thereby shortening the duration of noise and vibration during adjustment, reducing discomfort to the patient's ears from noise, and minimizing the impact of vibration on the fixation of the patient's head, thus improving the patient's medical experience. Furthermore, by combining large-scale rapid adjustments with small-scale fine adjustments, the device ensures both adjustment efficiency and coordination between head fixation and head support, improving its usability.

[0052] This implementation forms a three-point three-dimensional clamping effect by using the clamping blocks 12 on both sides and the airbag 15 at the bottom, which can effectively improve the fixation effect; and the synchronous dynamic movement of the three can make the device adaptable to different head sizes, improving the comprehensiveness and effectiveness of fixation.

[0053] like Figure 3 and Figure 4As shown, a second air supply assembly for supplying air to the airbag 15 is provided on the left side of the adjustment frame 8. The second air supply assembly includes a second air supply box 7 bolted to the other side of the adjustment frame 8, a second air supply plate 24 slidably fitted inside the second air supply box 7, a second air supply rod 23 bolted to the side of the upper rack 17 near the second air supply box 7, the second air supply rod 23 extending into the second air supply box 7 and bolted to the second air supply plate 24; a second vent hole is opened on the side of the second air supply box 7 away from the adjustment frame 8 (the second vent hole can ensure that the second air supply box 7 is connected to the outside world and ensure that the second air supply plate 24 moves smoothly); the top of the second air supply box 7 is connected to the side wall of the airbag 15.

[0054] Specifically, such as Figure 3 and Figure 4 As shown, during the process of gear 16 driving the upper rack 17 to move to the right, the upper rack 17 will drive the second air supply rod 23 and the second air supply plate 24 to move to the right, thereby delivering the gas in the second air supply box 7 to the airbag 15, causing the airbag 15 to inflate, thus providing flexible support for the patient's head and improving the patient's comfort. Moreover, during the operation, the patient's head may experience slight vibrations. If only the support plate 21 provides rigid support, the patient's head will collide with the support plate 21. However, the inflated airbag 15 has good support and deformation capabilities, which can support the patient's head while adapting to the slight vibrations of the patient's head, playing a good buffering role. This ensures the stability of the patient's head and the safety of the patient's head, avoiding unnecessary collisions. This embodiment, through the design of mechanical structure and gas dynamics, can adaptively fix heads of different sizes while providing dynamic and flexible support for the patient's head. This ensures the stability of the patient's head while improving the patient's comfort and safety. Moreover, the entire process can be fully automated by simply rotating gear 16, without the need for human assistance from medical staff or patients, effectively improving surgical efficiency and surgical outcomes.

[0055] Example 2:

[0056] The difference from Example 1 is that, as Figure 1 As shown, the bottom of the adjustment frame 8 is provided with an angle adjustment component for adjusting the angle of the adjustment frame 8. The angle adjustment component includes a support column 6, and a second drive component 4 (in this embodiment, the second drive component 4 is an AC motor) is bolted to the top of the support column 6. The output shaft of the second drive component 4 is bolted to the bottom of the adjustment frame 8, and the controller is connected to the second drive component 4 via an electrical signal. A bending frame 3 is rotatably connected to the bottom of the support column 6.

[0057] Specifically, such as Figure 1As shown, the second drive unit 4 is activated by the controller. The output shaft of the second drive unit 4 will drive the adjustment frame 8 and all the components on the adjustment frame 8 to rotate horizontally, thereby adjusting the horizontal angle of the patient's head, making it easier for doctors to perform surgery on the patient's head at different angles and improving the convenience of the surgery.

[0058] Example 3:

[0059] The difference from Example 2 is that, as Figure 1 As shown, the bending frame 3 is equipped with a pitch adjustment assembly for driving the support column 6 to rotate around the bending frame 3. The pitch adjustment assembly includes a third drive component 5 embedded in the side wall of the bending frame 3. The output shaft of the third drive component 5 is fixedly connected to the bottom of the support column 6 with bolts. The controller is connected to the third drive component 5 via an electrical signal.

[0060] Specifically, such as Figure 1 As shown, the controller starts the third drive unit 5 (in this embodiment, the third drive unit 5 is an AC motor), and the output shaft of the third drive unit 5 will drive the support column 6 to rotate around the bending frame 3, as shown. Figure 7 As shown, when the support column 6 rotates to the left around the bending frame 3, the patient's head will tilt backward to the left; when the support column 6 rotates to the right around the bending frame 3, the patient's head will tilt forward to the right. By combining the rotation of the adjustment frame 8 with the rotation of the support column 6, the adjustable range of the patient's head can be effectively improved, while adapting to the patient's different body positions during surgery, further improving the convenience and comprehensiveness of the surgery.

[0061] Example 4:

[0062] The difference from Example 3 is that, as Figure 1 and Figure 7 As shown, the bottom of the hospital bed 22 is detachably bolted to a mounting plate 1, and the bottom of the mounting plate 1 is equipped with a height adjustment assembly for adjusting the height of the adjustment frame 8. The height adjustment assembly includes an electric cylinder 2 bolted to the bottom of the mounting plate 1, and the output shaft of the electric cylinder 2 is bolted to the top of the bending frame 3; a controller is used to control the operation of the electric cylinder 2.

[0063] Specifically, such as Figure 1 and Figure 7 As shown, by controlling the operation of the electric cylinder 2 through the controller, the height of the bending frame 3, the support column 6 and the adjustment frame 8 can be adjusted, thereby adjusting the height of the airbag 15, the clamping block 12 and the patient's head. By integrating the head's horizontal angle, pitch angle and position height adjustment functions, the device can better meet the surgeon's needs according to the patient's actual situation, effectively improving the device's adaptability and thus achieving better surgical results.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
