[0058] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0059] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0060] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0061] Example 1

[0062] This embodiment provides an adjustable prone position pad for spinal surgery, the adjustable prone position pad for spinal surgery comprising:

[0063] A body positioning cushion base, and a widening module, a lifting module, a supporting module and a control module configured on the body positioning cushion base; wherein:

[0064] The widening module includes a base that can be extended along a horizontal direction;

[0065] The elevation module is arranged on the base and comprises at least one elevation platform, each elevation platform being extendable in a vertical direction;

[0066] The support module includes at least one support plate and a plurality of movable support pads arranged on the at least one support plate, wherein the support plate is placed on at least one elevated platform and connected to the elevated platform;

[0067] The control module is used to control the base to extend along the horizontal direction, and control each elevation platform to extend along the vertical direction.

[0068] In this embodiment, if Figure 1 As shown, the adjustable prone position cushion for spinal surgery consists of a widening module, a lifting module, a supporting module, a locking module and a control module 7. The widening module adjusts the inner and outer dimensions of the position cushion by contracting the lateral dimension. The control module 7 can control the widening module to expand or contract the width of the cushion body to adapt to the width of the shoulders, chests and pelvis of different patients, ensuring that the position cushion can fit the patient's body closely, reducing movement and discomfort during surgery, and improving the safety and efficiency of the surgery; the lifting module changes the height of the position cushion through an electric lifting structure, and the control module 7 can control the raising or lowering of the lifting module to make the patient's position reach the optimal surgical state, optimize the surgical field of view, enable the doctor to see the surgical area more clearly, and adjust the patient's position according to the surgical needs, which is conducive to the smooth progress of the surgery and reduces the surgical risks.

[0069] Specifically, the support module is usually made of memory foam, gel pad or other soft and supportive materials, and is laid on top of the lifting module. Through the setting of the support module, the patient's weight can be evenly distributed, the pressure points can be reduced, and comfortable prone support can be provided to protect the patient's skin from being crushed, reduce postoperative pain, maintain the natural curve of the patient's spine, and reduce discomfort caused by lying prone for a long time; the locking module uses the locking buckle 14 and the fixing strap 8. After the widening module and the lifting module are adjusted into place, the locking function of the locking buckle 14 is used to fix them at the current size and height, and the fixing strap 8 is used to fix the patient's posture , ensuring that the positioning cushion will not accidentally move or deform due to external force during the operation, providing stable support, ensuring the safe conduct of the operation, and reducing the risk of the positioning cushion needing to be adjusted again due to movement during the operation; the control module 7 receives external input (such as patient circumference data, operation type, etc.), calculates the most suitable positioning cushion size and height, and then sends instructions to the widening module and the raising module for automatic adjustment. At the same time, the control module 7 also supports manual operation to meet the needs in special circumstances. The automated adjustment improves the efficiency and safety of surgical preparation, and the manual adjustment function improves the flexibility of adjusting the positioning cushion.

[0070] The present invention realizes height adjustment and inside-out adjustment of the position pad through the widening module and the raising module, which can adapt to the needs of different patient bodies and different surgeries; the width of the pad body is expanded or contracted by the widening module to adapt to the width of the shoulders, chests and pelvis of different patients, ensuring that the position pad can fit the patient's body closely, reducing movement and discomfort during surgery, and improving the safety and efficiency of the surgery; the height of the position pad is adjusted by the raising module to make the patient's position reach the optimal surgical state, optimize the surgical field of view, and enable the doctor to see the surgical area more clearly, which is conducive to the smooth progress of the surgery and reduce the surgical risk; the patient's weight can be evenly distributed through the supporting module, reducing pressure points, not affecting the respiratory system, and reducing the discomfort caused by lying prone for a long time; the size and height of the position pad are fixed by the locking module, ensuring that the position pad will not be accidentally moved or deformed due to external force during the operation, ensuring the safe operation, and reducing the risk of re-adjustment due to movement of the position pad during the operation; the size of the position pad is automatically adjusted by the control module 7, which improves the preparation efficiency and safety of the surgery, and the manual adjustment function improves the flexibility of the position pad adjustment.

[0071] Furthermore, the widening module comprises:

[0072] Four retractable connecting rods;

[0073] Two of the four telescopic connecting rods are respectively placed on both sides of the other two telescopic connecting rods and connected to the ends of the other two telescopic connecting rods, and each telescopic connecting rod can be extended inside and outside the rod.

[0074] In this embodiment, the widening module is composed of two first telescopic connecting rods 1 and two second telescopic connecting rods 2. The two first telescopic connecting rods 1 are respectively placed on both sides of the two second telescopic connecting rods 2 and connected to the ends of the two second telescopic connecting rods 2. Each first telescopic connecting rod 1 has an independent lengthening function, and each second telescopic connecting rod 2 has an independent widening function. Figure 2 Each telescopic connecting rod can be freely extended to reach the required width. After the width is adjusted, the size is fixed by locking buckles 14. The two first telescopic connecting rods 1 are located on both sides of the widening module to play a role of fixing and supporting. The two second telescopic connecting rods 2 are located between the first telescopic connecting rods 1 and have independent widening functions, which can be flexibly adjusted according to the patient's body shape and surgical needs.

[0075] Specifically, before the operation, the control module 7 initializes the width of the positioning cushion according to the patient's circumference data and the type of operation. During the operation, the medical staff can manually adjust the length of the retractable connecting rod according to the actual operation needs to match the width and length of the widening module with the patient's body shape. The retractable connecting rod design of the widening module makes it possible to flexibly adjust the width of the positioning cushion according to the patient's body shape, thereby improving the comfort and safety of the operation. By quickly adjusting the width of the widening module, the medical staff can quickly prepare a suitable positioning cushion for the patient, thereby reducing the operation preparation time and improving the operation efficiency. The design of the widening module enhances the overall stability of the positioning cushion, prevents the patient from moving due to unstable position during the operation, and reduces the risk of the operation. The adjustable width of the positioning cushion can reduce the occurrence of complications such as pressure sores caused by the patient maintaining the same position for a long time, thereby improving the quality of the operation.

[0076] Furthermore, the elevated platform comprises:

[0077] base, electric riser and damped directional controls;

[0078] The base is configured on the base;

[0079] The electric lifter is placed on the base and is used to adjust the lifting height;

[0080] The damping direction controller is placed on the electric lifter to control the direction and speed of lifting.

[0081] In this embodiment, if Figure 3The lifting platform 3 is composed of a base 9, an electric lifter 10 and a damping direction controller 11. The base 9 is fixed at the connection between the first telescopic connecting rod 1 and the second telescopic connecting rod 2. The electric lifter 10 adjusts the lifting height. The damping direction controller 11 controls the lifting direction and speed. Each lifting platform 3 has independent lifting ability and can adjust the height independently. The base 9 is the basic part of the lifting platform 3, which is made of sturdy and durable materials to ensure that the weight of the entire position cushion and the patient can be stably supported during the lifting process, provide stable support, ensure the stability of the position cushion during the lifting process, and prevent patient discomfort or surgical risks caused by shaking or tilting; the electric lifter 10 is driven by a motor to achieve the lifting function. Medical staff can adjust the height of the electric lifter 10 in each lifting platform 3 through the control panel of the control module 7 or the remote control to achieve precise height adjustment, meet the needs of different surgical positions, and ensure the comfort and safety of the patient during the operation. Compared with the traditional manual lifting method, the electric lifter 10 is more labor-saving and convenient, which reduces the workload of medical staff; the damping direction controller 11 is used to control the direction and speed of the lifting of the lifting platform 3. The damping technology is used to provide stable resistance during the lifting process to prevent the position cushion from sudden lifting or shaking. Medical staff can accurately control the lifting direction and speed through the control panel of the control module 7 or the knob on the controller. The damping direction controller 11 ensures the stability of the position cushion during the lifting process, reducing the patient's sense of vibration and discomfort.

[0082] Specifically, during the operation, the medical staff will adjust the height of the lifting platform 3 through the control module 7 or the remote control according to the patient's body shape, surgical site and the height of the positioning cushion required for the type of surgery, and use the damping direction controller 11 to control the direction and speed of lifting. In this way, the positioning cushion can be accurately adjusted to the required height and inclination angle to provide the patient with a stable, comfortable and safe surgical position; through the application of the lifting platform 3 in the surgical positioning cushion, the needs of different surgical positions can be met, the comfort and safety of the surgery can be improved, the workload of medical staff can be reduced, and the efficiency of the surgery can be improved.

[0083] Furthermore, the support module comprises:

[0084] A shoulder support plate, a chest support plate, an iliac support block, and a plurality of movable support pads;

[0085] The shoulder support plate is arranged in a direction parallel to the telescopic connecting rod, and a slide rail is arranged below the shoulder support plate, and is connected to the lifting platform through the slide rail;

[0086] The chest support plate is placed parallel to the left side of the shoulder support plate, a first groove is provided on a side close to the shoulder support plate, and a slide rail is provided below the chest support plate, which is connected to the lifting platform through the slide rail;

[0087] The iliac support block is placed parallel to the left side of the chest support plate and connected to the lifting platform;

[0088] The multiple movable support pads are placed on the shoulder support plate and the chest support plate. The shoulder support plate and the chest support plate have a first guide roller for the movable support pad to move up and down and a second guide roller for moving inward and outward. The movement of each movable support pad is controlled by a moving trajectory control method.

[0089] In this embodiment, the support module is composed of a shoulder support plate 4, a chest support plate 5 and eight first support pads 6. The shoulder support plate 4 is arranged in a direction parallel to the second telescopic connecting rod 2. Figure 6 A slide rail 15 is provided under the shoulder support plate 4, which is connected to two of the lifting platforms 3 through the slide rail 15 to ensure that when the height of the position pad is adjusted, the position of the shoulder support plate 4 also changes accordingly; the shoulder support plate 4 ensures that the shoulder is not compressed through its shape design, reducing the patient's sense of oppression and discomfort during the operation. By adjusting the position of the shoulder support plate 4, the surgical field of view can be optimized, allowing medical staff to see the surgical site more clearly, thereby improving the accuracy and safety of the operation.

[0090] Specifically, the chest support plate 5 is placed parallel to the left side of the shoulder support plate 4. Figure 7 As shown, the chest support plate 5 is provided with a first groove 16 on one side close to the shoulder support plate 4, and a slide rail 15 is also provided under the chest support plate 5, which is connected to the other two lifting platforms 3 through the slide rail 15, so as to facilitate medical staff to adjust its position according to the operation requirements; by providing the first groove 16, the abdomen of the patient is prevented from being compressed and affecting the breathing when the patient is in the prone position, and the position and height of the chest support plate 5 can be adjusted to optimize the patient's respiratory function and ensure that the patient can breathe smoothly during the operation; the iliac support block 20 is placed parallel to the left side of the chest support plate 5 and is connected to the lifting platform 3, and can be independently raised to support the patient's ilium and fix the patient's pelvic position to ensure that the patient's body position is stable during the operation and prevent the accuracy of the surgical operation from being affected by body position movement during the operation.

[0091] Specifically, eight first support pads 6 are respectively placed on both sides of the shoulder support plate 4 and the chest support plate 5 in a direction parallel to the first retractable connecting rod 1. The support pads on the same side have the ability to separate and merge. The support plate has a first guide roller for the support pad to move up and down and a second guide roller for moving in and out. Among them, two support pads are used to support the shoulders, four support pads are used to support the chest, and two support pads are used to support the ilium. Medical staff can adjust the position and number of support pads according to the patient's body shape and surgical needs to ensure that the patient receives comprehensive support. The design of the support pads can fully support the patient's shoulders, chest and ilium to reduce discomfort during the operation; the separation and merging function of the support pads makes it easy for medical staff to make adjustments according to the patient's body shape and surgical needs to ensure the best support effect; by adjusting the position and number of support pads, the risk of pressure sores caused by patients maintaining the same body position for a long time can be reduced.

[0092] During the operation, medical staff adjust the positions of the shoulder support plate 4 and the chest support plate 5 according to the patient's body shape, surgical site and the support position required for the type of operation, and adjust the number and position of the support pads as needed to ensure that the patient's shoulders, chest and ilium are stably and comfortably supported, ensuring the correct and safe posture during the operation; through the design of the support module, stable and comfortable support can be provided to the patient during the operation, and the surgical field of view can be optimized, the shoulders can be protected, the respiratory function can be optimized, and the risk of pressure sores can be reduced.

[0093] Further, the movement of each movable support pad is controlled by a movement trajectory control method, comprising:

[0094] Calculate the target position of each removable support cushion according to its function and the type of surgery;

[0095] Using a path planning method to plan the shortest moving path for each movable support pad to move from a current position to a target position;

[0096] Calculate the moving priority of each movable support pad according to the function and moving amount of each movable support pad;

[0097] When the shortest moving paths of the movable support pads intersect, the movable support pad with a larger moving priority has priority to pass, and the movable support pad with a smaller moving priority enters the waiting area;

[0098] The movement priority of the movable support pads in the waiting area is recalculated until each movable support pad reaches the target position.

[0099] In this embodiment, the position of the movable support pad is adaptively adjusted according to the type of surgery of the patient and the different needs of different patients. By adjusting the movable support pads with different functions during the surgery, the specific needs of the patient during the surgery can be met. The movable support pad includes eight support cushions and a second support pad 19 with a smaller size and a massage function. The second support pad 19 can be moved during the surgery to massage different parts of the patient, preventing blood circulation from being blocked due to a posture for a long time, and providing comfort to the patient during the surgery.

[0100] Specifically, a target position is calculated for each movable support pad according to the type of surgery and the specific needs of the patient, combined with the function of each movable support pad, such as the shoulder support pad, chest support pad, iliac support pad, massage support pad, etc. This target position is determined based on the convenience of the surgeon's operation and the comfort of the patient, ensuring that the support pad can be accurately moved to the position required for the surgery, providing the surgeon with the best surgical field of view and operating space, improving the efficiency and safety of the surgery, and ensuring the comfort of the patient during the surgery; using the path planning algorithm, a shortest moving path from the current position to the target position is planned for each movable support pad, reducing the moving time and distance of the support pad. The path planning algorithm can be an A* algorithm, a Dijkstra algorithm, an RRT algorithm, etc. By planning the shortest moving path for each movable support pad, the moving efficiency can be improved.

[0101] The movement priority of each movable support cushion is calculated based on its function (such as providing additional support, adjusting the patient's position, etc.) and the movement amount (i.e., the distance from the current position to the target position). The priority can be dynamically adjusted according to the surgical requirements. The priority calculation formula is as follows:

[0102] P = θ1 × β1 + θ2 × β2;

[0103] In the formula, P is the priority of each movable support pad, θ1 is the functional weight of the movable support pad, θ2 is the weight of the movement amount, β1 is the functional value of the movable support pad, which can be set in advance according to the specific needs of the surgery type, and β2 is the movement amount. The weight value can be dynamically adjusted according to the actual needs of the surgery. For example, in spinal surgery, the doctor may need to quickly adjust the patient's position for the next step. At this time, the priority of the support pads related to the position adjustment (such as the chest support pad and the shoulder support pad) will be increased accordingly. By dynamically adjusting the priority, it can be ensured that the key support pads can be moved first to meet the emergency needs during the operation and avoid collisions during the movement.

[0104] When the shortest moving paths of two or more movable support pads intersect, the moving priority is used to determine which support pad has priority. The support pad with a smaller moving priority will enter the waiting area and wait for the support pad with a larger priority to pass before continuing to move, thereby avoiding collisions and conflicts between the support pads. For example, during surgery, if the moving paths of the chest support pad and the shoulder support pad intersect, and the chest support pad has a higher priority, the chest support pad will have priority and the shoulder support pad will enter the waiting area to wait. When the support pad with a higher priority passes, the moving priority of the support pads in the waiting area is recalculated, and the movement of the support pads is controlled according to the new priority and path planning results until each support pad reaches its target position, thereby ensuring that all support pads can reach the required positions for surgery in the predetermined order and position.

[0105] Furthermore, a second groove is provided on a side of the shoulder support plate close to the chest support plate, and two shoulder grooves are provided on a side away from the chest support plate.

[0106] In this embodiment, the shoulder support plate 4 is provided with a second groove 13 on one side close to the chest support plate 5, and two shoulder grooves 12 are provided on the side away from the chest support plate 5. Figure 4 The shoulder support plate 4 is provided with two shoulder grooves 12 on one side away from the chest support plate 5. By providing the shoulder grooves 12, the shape of the upper arm after being stretched forward during the operation can be adapted to prevent the shoulder from being compressed; the two grooves correspond to the patient's left shoulder and right shoulder respectively, providing support for the shoulder, ensuring that the shoulder maintains the correct posture during the operation, while reducing the discomfort caused by maintaining the same posture for a long time; Figure 5 A second groove 13 is provided on one side of the shoulder support plate 4 close to the chest support plate 5. The design of the second groove 13 can adapt to the shape of a woman's chest and avoid squeezing the chest. The design of the groove can reduce the friction and pressure between the chest and the support plate, so that the patient can get better relaxation and support during the operation.

[0107] Specifically, during the operation, the medical staff slides the shoulder support plate 4 to the appropriate position according to the patient's body shape, surgical site and the shoulder support position and strength required for the type of operation, and ensures that the second groove 13 and the shoulder groove 12 fit perfectly with the patient's shoulders. After the adjustment is completed, the medical staff will use the fixing strap 8 to fix the patient on the positioning pad to ensure a stable position during the operation; by providing stable and comfortable support, the shoulder support plate 4 helps to reduce the patient's movement during the operation and the time for the medical staff to adjust the position, thereby improving the efficiency of the operation; the design of reducing friction and pressure helps to reduce the risk of complications such as pressure sores and nerve damage caused by maintaining the same position for a long time; the design of the shoulder support plate 4 can provide patients with a closer and more comfortable support, and ensure that the position during the operation is correct and safe, while improving the efficiency of the operation and reducing the risk of complications.

[0128] Example 2

[0129] The invention discloses an application of an adjustable prone position pad for spinal surgery, and the application of the adjustable prone position pad for spinal surgery in prone position surgery.

[0130] In this embodiment, the adjustable prone position pad for spinal surgery can be applied to spinal surgery. During spinal surgery, the patient often needs to be in a prone position. The adjustable prone position pad can be adjusted according to the patient's height, weight, chest width and abdominal cavity capacity to prevent the chest and abdomen from being compressed. For example, in posterior thoracic and lumbar spine surgery, the position pad can be placed with the head low and the feet high, while in posterior cervical spine surgery, it is placed with the head high and the feet low, which can conform to the anatomical structure of the spine and better expose the surgical field of view. The height of the position pad can be adjusted independently to achieve adjustment according to the patient's body shape and surgical needs, so as to effectively reduce skin pressure and prevent the occurrence of pressure sores. At the same time, the softness and pressure resistance of the position pad can also provide better support and protection for patients.

[0131] Specifically, the prone position may cause pressure on the patient's chest and abdomen, affecting respiratory and circulatory functions. The adjustable prone position pad reduces intra-abdominal pressure by suspending the chest and abdomen, thereby maintaining normal respiratory rate, ventilation function and venous return. In addition, the position pad can also help patients maintain unobstructed breathing and reduce the risk of respiratory and circulatory system complications caused by improper body position. The use of the adjustable prone position pad can fully expose the surgical field of view, allowing the surgeon to see the surgical site more clearly, thereby improving the accuracy and success rate of the operation; by reducing skin pressure and preventing the occurrence of pressure sores, as well as maintaining normal respiratory and circulatory functions, the adjustable prone position pad can significantly reduce possible complications during surgery, such as respiratory disorders, circulatory disorders, nerve damage, etc.; the softness and pressure resistance of the position pad can provide better support and protection for patients and reduce discomfort during surgery. At the same time, the personalized adjustment of the position pad can also meet the needs of different patients and improve the comfort and safety of surgery.
