Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical devices, and in particular to an orthopedic spine postoperative protective device. Background Art
[0002] In the prior art, orthopedic spinal postoperative protective devices (such as spinal braces and fixed mattresses) are mostly fixed structures (such as non-adjustable support cushions) in actual use. Their height and shape are preset before use and cannot be adjusted in real time as the patient's body position changes (such as turning over, lying on the side, or slight movement). When the patient's body pressure causes the support component (such as the pad) to deform or shift, a height difference between the support and the mattress / bed surface is likely to occur, causing localized force concentration on the spine (such as the waist hanging in the air due to the collapse of the support cushion after lumbar surgery, or excessive flexion and extension of the neck due to pillow displacement after cervical surgery). This increases the risk of traction on the surgical site and loosening of the fusion segment, affecting the stability of postoperative healing. Summary of the Invention
[0003] The purpose of the present invention is to provide an orthopedic spine postoperative protective device to solve the problems raised in the above background technology.
[0004] In order to achieve the above object, the present invention provides the following technical solutions:
[0005] An orthopedic spine postoperative protective device comprises a medical bed, a mattress is provided on the medical bed, a notch is opened on the mattress, and protective mechanisms are provided on the medical bed and the mattress.
[0006] As a preferred embodiment, the protective mechanism includes a protective plate, a mounting slot is provided on the medical bed, an electric cylinder is provided on the mounting slot, a support plate is driven and connected to the electric cylinder, a support frame is connected to the support plate, an arc-shaped support block is connected to the support frame, a pad and a protective plate are provided on the arc-shaped support block, a reserved slot is provided on the protective plate, and a monitor is provided on the reserved slot.
[0007] Furthermore, the medical bed is adjusted to a horizontal state before the operation to ensure that the mattress is flat and the position of the groove corresponds to the part of the patient's spine that needs support after the operation (such as the lumbar spine and thoracic spine).
[0008] Furthermore, the electric cylinder is electrically connected to the external device. The backup battery level is then checked to ensure that the electric cylinder and monitor remain powered stably after a power outage. When the guardrail is retracted, it prevents the patient from falling out of bed when turning over.
[0009] Furthermore, after the operation, the patient lies on the mattress with the surgical site aligned directly above the slot; the medical staff controls the electric cylinder to drive the support plate up and down according to the patient's body shape and surgical site, driving the support frame and the arc-shaped support block to move synchronously, so that the pad (concave structure) fits the patient's torso (such as waist and back) below the surgical site, and initially achieves support. At this time, the slider slides along the slide to ensure that the support frame moves smoothly and avoids deviation. After the patient lies down, the body pressure causes the pad (medical-grade elastic material) to deform, and the monitor (infrared distance sensor or TOF sensor) detects the relative position of the pad surface and the mattress in real time through the reserved slot: if it is detected that the two are not flush (there is a height difference), the monitor triggers a signal, and the electric cylinder fine-tunes the height of the support plate until the pad is flush with the mattress after being compressed, ensuring that the spine is evenly stressed and avoiding local compression;
[0010] Furthermore, if the patient turns over or slightly changes his body position, causing the pad to deform and shift, the monitor repeats the above detection and adjustment process to maintain dynamic balance.
[0011] As a preferred embodiment, a slider is connected to the support frame.
[0012] As a preferred embodiment, the pad is concave.
[0013] Furthermore, the pad is convex or flat.
[0014] Furthermore, the cushion block can be configured in a convex or flat structure according to different postoperative recovery stages and spinal support requirements:
[0015] When a convex setting is adopted, its convex arc is adapted to the physiological curvature of the human spine (such as lumbar lordosis and cervical lordosis), which can provide targeted support for specific segments of the spine in the early postoperative period, maintain the natural curvature, and avoid excessive sinking of the spine due to body weight;
[0016] When the flat setting is used, the surface remains horizontal, which is suitable for scenarios in the middle and late stages after surgery where the local support strength needs to be reduced and moderate spinal movement is allowed, or for areas such as the thoracic spine that need to maintain a neutral position, reducing rigid constraints on the spine and improving lying comfort.
[0017] By switching between convex, flat or concave shapes (as described above), the cushion block (13) can flexibly adapt to the support requirements of different stages after spinal surgery, thereby enhancing the versatility and rehabilitation adaptability of the device.
[0018] As a preferred embodiment, the medical bed is provided with a slide groove, and a slider is slidably fitted on the slide groove.
[0019] As a preferred embodiment, the medical bed is also provided with a backup battery.
[0020] As a preferred embodiment, the pad is made of medical-grade elastic material, and the elastic material is silicone, polyurethane foam or memory cotton.
[0021] As a preferred embodiment, the pad is made of medical-grade elastic material, and the elastic material is one or a combination of silicone, polyurethane foam or memory cotton.
[0022] As a preferred embodiment, the monitor is located at one end of the mattress.
[0023] As a preferred embodiment, the monitor includes but is not limited to an infrared distance sensor and a TOF sensor.
[0024] As a preferred embodiment, the monitor is used to detect the flush state of the pad and the mattress; the pad is deformed by pressure, and the monitor determines whether the pad and the mattress are in a flush state by identifying the relative position relationship between the pad and the mattress, and adjusts the flushness of the pad and the mattress based on the judgment result.
[0025] As a preferred embodiment, the medical bed is provided with guardrails.
[0026] Furthermore, as postoperative recovery progresses, medical staff can replace pads of different hardness (Shore hardness 30-60HA) according to rehabilitation needs (such as using harder silicone material to strengthen fixation in the early stage, and replacing it with memory foam to improve comfort in the later stage), and adjust the support strength through electric cylinders to gradually adapt to the patient's needs for spinal mobility.
[0027] Furthermore, when the patient needs to leave the bed, the power supply of the electric cylinder is turned off, and the support plate drives the protective mechanism to reset to its initial position; the elastic state of the pad and the sensitivity of the monitor are regularly checked to ensure the stable performance of the device, and the backup battery ensures normal operation during power outages.
[0028] Compared with the prior art, the present invention has the following beneficial effects:
[0029] 1. The present invention uses a monitor (infrared distance sensor or TOF sensor) to detect the levelness of the pad and mattress in real time. Combined with the fine-tuning function of the electric cylinder, it can adjust the support height when the patient turns over, changes position, or the pad is compressed and deformed, ensuring that the pad is always flush with the mattress, avoiding uneven force on the spine due to height difference, and solving the problem that traditional fixed support devices are difficult to adapt to the patient's dynamic position changes.
[0030] 2. The present invention uses protective mechanisms and replaceable pads to flexibly switch between concave, convex or flat structures according to the patient's surgical site (such as lumbar spine, cervical spine, thoracic spine) and different stages after surgery (early fixation, mid-to-late stage activity). The concave structure can disperse pressure, the convex structure can provide targeted support to maintain physiological curvature, and the flat structure adapts to the neutral position requirements, avoiding excessive flexion and extension or compression of the spine, effectively reducing the risk of traction and displacement of the surgical site, and providing a stable mechanical environment for postoperative healing.

They do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientation structure, and should not be understood as a limitation of the present invention.
[0042] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.
[0043] Example 1
[0044] See also Figure 1-4 The present embodiment provides an orthopedic spine postoperative protective device, comprising a medical bed 1, a mattress 3 provided on the medical bed 1, a slot 4 provided on the mattress 3, and protective mechanisms provided on the medical bed 1 and the mattress 3.
[0045] The protective mechanism includes a protective plate 5, a mounting slot 6 is provided on the medical bed 1, an electric cylinder 8 is provided on the mounting slot 6, a support plate 9 is driven and connected to the electric cylinder 8, the support plate 9 is connected to a support frame 10, an arc-shaped support block 12 is connected to the support frame 10, a pad 13 and a protective plate 5 are provided on the arc-shaped support block 12, a reserved slot 14 is provided on the protective plate 5, and a monitor 15 is provided on the reserved slot 14.
[0046] Furthermore, before the operation, the medical bed 1 is adjusted to a horizontal state to ensure that the mattress 3 is flat and the position of the notch 4 corresponds to the part of the patient's spine that needs to be supported after the operation (such as the lumbar spine and thoracic spine).
[0047] Specifically, the electric cylinder 8 is electrically connected to the external device. The backup battery 7 is then checked for power to ensure that the electric cylinder 8 and the monitor 15 are powered stably after a power outage. The guardrail 2 can prevent the patient from falling out of bed when the protective mechanism is retracted.
[0048] Specifically, after surgery, the patient lies on mattress 3, with the surgical site aligned directly above notch 4. Medical staff, based on the patient's body shape and the surgical site, control electric cylinder 8 to raise and lower support plate 9, driving the synchronous movement of support frame 10 and arc-shaped support block 12. This allows pad 13 (concave structure) to fit the patient's torso (e.g., waist or back) below the surgical site, achieving initial support. At this point, slider 11 slides along slot 16, ensuring smooth movement of support frame 10 and preventing deviation.
[0049] When the patient lies down, the pressure of the body causes the cushion 13 (medical-grade elastic material) to deform. The monitor 15 (infrared distance sensor or TOF sensor) detects the relative position of the surface of the cushion 13 and the mattress 3 in real time through the reserved groove 14. If the monitor detects that the two are not flush (there is a height difference), the monitor 15 triggers a signal, and the electric cylinder 8 fine-tunes the height of the support plate 9 until the cushion 13 is flush with the mattress 3 after being compressed, ensuring uniform force on the spine and avoiding localized compression.
[0050] Specifically, if the patient turns over or slightly changes his body position, causing the pad 13 to deform and shift, the monitor 15 repeats the above detection and adjustment process to maintain dynamic balance.
[0051] The support frame 10 is connected to a slider 11 .
[0052] The pad 13 is arranged in a concave shape.
[0053] A slide groove 16 is provided on the medical bed 1 , and a slider 11 slides on the slide groove 16 .
[0054] The medical bed 1 is also provided with a backup battery 7 .
[0055] Specifically, the cushion block 13 is made of medical-grade elastic material, and the elastic material is silicone, polyurethane foam or memory cotton.
[0056] Specifically, the cushion block 13 is made of medical-grade elastic material, and the elastic material is one of silicone, polyurethane foam, or memory cotton, or a combination thereof.
[0057] Furthermore, the pad 13 is convex or flat.
[0058] Furthermore, the cushion block 13 can be configured in a convex or flat structure according to different postoperative recovery stages and spinal support requirements:
[0059] Furthermore, when a convex shape is used, its convex curvature is adapted to the physiological curvature of the human spine (such as lumbar lordosis and cervical lordosis), which can provide targeted support for specific segments of the spine in the early postoperative period, maintain the natural curvature, and avoid excessive sinking of the spine due to body weight.
[0060] Furthermore, when a flat setting is adopted, its surface remains horizontal, which is suitable for scenarios in the middle and late stages after surgery where the local support strength needs to be reduced and moderate spinal movement is allowed, or for parts such as the thoracic spine that need to maintain a neutral position, reducing rigid constraints on the spine and improving lying comfort.
[0061] Furthermore, by switching between convex, flat or concave shapes (as described above), the cushion block 13 can flexibly adapt to the support requirements at different stages after spinal surgery, thereby enhancing the versatility and rehabilitation adaptability of the device.
[0062] The monitor 15 is located at one end of the mattress 3 .
[0063] The monitor 15 includes but is not limited to an infrared distance sensor and a TOF sensor.
[0064] The monitor 15 is used to detect the flush state of the pad 13 and the mattress 3; the pad 13 is deformed by pressure, and the monitor 15 determines whether the pad 13 and the mattress 3 are in a flush state by identifying the relative position relationship between the pad 13 and the mattress 3, and adjusts the flushness of the pad 13 and the mattress 3 based on the judgment result.
[0065] The medical bed 1 is provided with a guardrail 2.
[0066] Furthermore, as the postoperative recovery progresses, medical staff can replace the pads 13 with different hardness (Shore hardness 30-60HA) according to rehabilitation needs (such as using harder silicone material to strengthen fixation in the early stage and replacing memory foam to improve comfort in the later stage), and adjust the support strength through the electric cylinder 8 to gradually adapt to the patient's needs for spinal mobility.
[0067] Specifically, when the patient needs to leave the bed, the power supply of the electric cylinder 8 is turned off, and the support plate 9 drives the protective mechanism to reset to the initial position; the elastic state of the pad 13 and the sensitivity of the monitor 15 are regularly checked to ensure the stable performance of the device.
[0068] Through the above operations, the device can achieve precise support, dynamic adaptation and safety protection after spinal surgery, taking into account both stability and comfort, and assisting patients in their postoperative recovery.
[0069] Example 2
[0070] Based on Example 1, this embodiment provides an orthopedic spine postoperative protective device with temperature sensing and zoning adjustment functions to address the problem of high local skin temperature and increased risk of pressure sores in patients who have undergone spinal surgery and are bedridden for a long time. The structure and function of the protective device are optimized, with the following specific improvements:
[0071] The pad 13 adopts a modular partition design and is divided into 3-5 independent units along the length of the spine (such as the cervical segment, upper thoracic segment, lower thoracic segment, upper lumbar segment, and lower lumbar segment). Each unit can be disassembled and replaced independently, and a micro heating / heating module (flexible electric heating film, micro fan) is embedded inside.
[0072] Furthermore, the temperature of a single unit is adjusted by an external controller (range 32-38°C, close to the human body's comfortable temperature).
[0073] A temperature and humidity sensor (such as SHT30) is added to the reserved groove 14 of the protective plate 5 and integrated with the original monitor 15 to detect the temperature (accuracy ±0.5°C) and humidity (accuracy ±2% RH) of the contact area between the pad 13 and the patient's skin in real time, and transmit the data to an external display screen (which can be installed on the medical bed guardrail 2) to facilitate intuitive monitoring by medical staff.
[0074] The electric cylinder 8 is connected to a linkage control module. When the temperature and humidity sensor detects that the temperature in a certain area exceeds 38°C or the humidity is greater than 60% RH, the heat dissipation module of the corresponding partition is automatically triggered (the micro fan is started); if the temperature is lower than 32°C (such as in winter or for patients with weak constitutions), the heating module is started (the flexible electric heating film works), and at the same time, the electric cylinder 8 fine-tunes the support height of the pad 13 in the area (±1-2mm), reducing the local compression time and realizing the dual dynamic adjustment of "temperature-pressure".
[0075] Furthermore, the protective plate 5 adopts a hollow grid structure (medical-grade ABS material) and is wrapped with a silicone pad on the edge that contacts the skin, which not only ensures structural strength but also enhances air circulation. Combined with the breathable material of the pad 13 (such as polyurethane foam with micropores), the feeling of stuffiness is further reduced.
[0076] Added "manual / automatic" dual mode control:
[0077] Automatic mode: Temperature control and height adjustment are triggered by sensors, suitable for scenarios where patients have weak independent movement ability;
[0078] Manual mode: Patients can manually adjust the temperature and height of a certain zone through the bedside button or remote control to improve ease of use (such as actively reducing the support strength of the pressure area when turning over).
[0079] Specifically, according to the patient's surgical segment (such as lumbar fusion), the corresponding partitioned pad unit is selected (such as a convex structure for the lumbar segment and a flat structure for other areas), and the temperature threshold (such as 36°C) and humidity threshold (50% RH) are preset through the controller.
[0080] Specifically, after the patient lies down, the temperature and humidity sensors monitor the status of the contact area in real time:
[0081] If the temperature of the lumbar spine pad rises to 39°C, the system automatically starts the cooling fan in that area and the electric cylinder fine-tunes the support height to 1mm to reduce the skin contact area;
[0082] If the humidity in the cervical spine reaches 65% RH (indicating sweating), the controller will emit an audible and visual alarm, and medical staff can replace the pad in that area (using a memory foam material with stronger moisture absorption).
[0083] Furthermore, in the early postoperative period (1-2 weeks), a heating module (maintaining 36-37°C) was used to promote local blood circulation.
[0084] In the middle and late stages (after 3 weeks), the heating is turned off, leaving only the heat dissipation function, and a soft, flat pad is used to accommodate the patient's increased activity needs.
[0085] Through temperature and humidity monitoring and dynamic temperature control, it can effectively avoid pressure sores and rashes caused by long-term pressure and stuffiness on local skin. It is especially suitable for patients who need to stay in bed for a long time (>2 weeks) after surgery.
[0086] The zoned design can be precisely adjusted to the postoperative needs of different spinal segments (such as the need for warmth after cervical spine surgery and the need for heat dissipation after lumbar spine surgery), solving the limitations of traditional single pads.
[0087] Specifically, patients can participate in the adjustment process independently, reduce agitation caused by discomfort, indirectly reduce the risk of spinal force fluctuations, and further assist postoperative healing.
[0088] While retaining the original "dynamic support and flexible structure", this embodiment achieves a further improvement from "mechanical protection" to "comprehensive comfort protection" through coordinated adjustment of multiple parameters such as "temperature-humidity-pressure", thereby enhancing its applicability in long-term rehabilitation and nursing scenarios.
[0089] It should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
[0090] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
