[0002] Craniotomy is a surgery that requires cutting the scalp and skull to expose brain tissue. After craniotomy, the surgical site is in an unhealed state, and a drainage tube is used to drain intracranial fluid or hematoma, etc., so external force should be avoided on the surgical site or drainage tube. However, the patient may unconsciously turn his head, etc., causing compression on the surgical site or drainage tube, resulting in damage to the surgical site. Therefore, in order to prevent damage to the surgical site, the head position needs to be kept fixed as much as possible.

The horizontal rod 26 extends along the horizontal direction X, and the orthographic projection of the horizontal rod 26 on the ground is located within the orthographic projection range of the bed board 1 on the ground;

[0070] A bracket 28, one end of which is connected to the crossbar 26, and the other end of which is connected to a camera 29;

[0071] The processor is respectively connected to the left slide 10, the left vertical telescopic rod 13, the left longitudinal telescopic rod 14, the right slide 15, the right vertical telescopic rod 18, the right longitudinal telescopic rod 19 and the camera 29, including: the left guide rail 11 includes a left guide rail motor, the left guide rail motor is connected to the left guide rail driver, and the left guide rail driver is connected to the left guide rail main control board; the right guide rail 16 includes a right guide rail motor, the right guide rail motor is connected to the right guide rail driver, and the right guide rail driver is connected to the right guide rail main control board; the left vertical telescopic rod 13 includes a left vertical telescopic rod motor, the left vertical telescopic rod motor is connected to the left vertical telescopic rod driver, and the left vertical telescopic rod driver is connected to the left vertical telescopic rod main control board; the right vertical telescopic rod 18 includes a right vertical telescopic rod Motor, the right vertical telescopic rod motor is connected to the right vertical telescopic rod driver, and the right vertical telescopic rod driver is connected to the right vertical telescopic rod main control board; the left longitudinal telescopic rod 14 includes the left longitudinal telescopic rod motor, the left longitudinal telescopic rod motor is connected to the left longitudinal telescopic rod driver, and the left longitudinal telescopic rod driver is connected to the left longitudinal telescopic rod main control board; the right longitudinal telescopic rod 19 includes the right longitudinal telescopic rod motor, the right longitudinal telescopic rod motor is connected to the right longitudinal telescopic rod driver, and the right longitudinal telescopic rod driver is connected to the right longitudinal telescopic rod main control board; the processors are respectively connected to the left guide rail main control board, the right guide rail main control board, the left vertical telescopic rod main control board, the right vertical telescopic rod main control board, the left longitudinal telescopic rod main control board and the right longitudinal telescopic rod main control board.

[0072] The fixing rod 30 is a cube, one end of the fixing rod 30 is connected to the side wall of the cross bar 26, and the other end is connected to the side wall of the vertical rod 27. Of course, the fixing rod 30 can also be a cylinder, which can be selected according to actual needs.

[0073] It should be noted that, in the present embodiment, the left slide 10, the left vertical telescopic rod 13, the left longitudinal telescopic rod 14, the right slide 15, the right vertical telescopic rod 18, and the right longitudinal telescopic rod 19 all adopt the existing technology, and the mechanical principles of the left slide 10, the left vertical telescopic rod 13, the left longitudinal telescopic rod 14, the right slide 15, the right vertical telescopic rod 18, and the right longitudinal telescopic rod 19 all rely on the process of converting the rotational motion of the motor into linear motion. Specifically, the left guide motor, the right guide motor, the left vertical telescopic rod motor, the right vertical telescopic rod motor, the left longitudinal telescopic rod motor and the right longitudinal telescopic rod motor all use 42 stepper motors; the left guide driver, the right guide driver, the left vertical telescopic rod driver, the right vertical telescopic rod driver, the left longitudinal telescopic rod driver and the right longitudinal telescopic rod driver are all drivers of model DRV8825; the left guide main control board, the right guide main control board, the left vertical telescopic rod main control board, the right vertical telescopic rod main control board, the left longitudinal telescopic rod main control board and the right longitudinal telescopic rod main control board all use Arduino main control boards, of course, not limited to this, and can also be set according to actual needs. The processor uses a computer to transmit signals to the Arduino main control board. In order to prevent the connection between the Arduino main control board and the processor from affecting the movement of the fixed system, the Arduino main control board is selected with a communication unit, and the Arduino main control board and the processor are wirelessly connected through the communication unit.

[0074] It is understandable that the left limit block 20 is provided to include a stacked left hard plate 21 and a left soft plate 22, and the left hard plate 21 is connected to the left longitudinal telescopic rod 14 on one side away from the left soft plate 22, that is, the left soft plate 22 will contact the patient's head, so the material of the left soft plate 22 is selected from medical sponge, so that the left soft plate 22 deforms with the contour of the patient's head when contacting the patient's head, has a high degree of fit and a small pressure on the contact position, and improves the sense of comfort. The left hard plate 21 can disperse the stress applied by one end of the left longitudinal telescopic rod 14 when the left soft plate 22 is based on the patient's head, thereby ensuring the safety and reliability of use. Similarly, the right limit block 24 is also set to a stacked right hard plate and a right soft plate, and the material of the right soft plate is also selected from medical sponge. Of course, it is not limited to this, and the left soft plate 22 and the right soft plate can be made of other materials that are deformed under pressure and rebound to the original state without pressure, and the left hard plate 21 and the right hard plate can be made of materials with higher hardness and less deformation under pressure, and this embodiment does not make specific restrictions on this. Since the cross bar 26 of the L-shaped rod 25 is connected to the bracket 28, the bracket 28 itself and the camera 29 connected to the bracket 28 are both subject to gravity, so that the cross bar 26 is subjected to a pulling force perpendicular to the ground, which can easily cause the cross bar 26 to deform. Therefore, a fixed rod 30 is provided with one end connected to the side wall of the cross bar 26 and the other end connected to the side wall of the vertical rod 27 to prevent or reduce the possibility of deformation of the L-shaped rod 25, and further ensure the accuracy of subsequent positioning point coordinate determination.

[0075] When the patient lies on the improved intelligent head-fixing protective bed provided in this embodiment, the camera 29 collects the patient's head image and transmits it to the processor. The processor determines the moving paths of the left limit block 20 and the right limit block 24 according to the head image. The processor sends corresponding signals to the left guide rail main control board, the left vertical telescopic rod main control board, and the left longitudinal telescopic rod main control board according to the moving path of the left limit block 20. The left guide rail main control board controls the left guide rail motor via the left guide rail driver, thereby controlling the movement of the left slider 12; the left vertical telescopic rod main control board controls the left vertical telescopic rod motor via the left vertical telescopic rod driver, thereby controlling the movement of the left longitudinal telescopic rod 14; the left longitudinal telescopic rod main control board controls the left longitudinal telescopic rod motor via the left longitudinal telescopic rod driver, thereby controlling the movement of the left limit block 20. Similarly, the processor controls the right guide rail motor, the right vertical telescopic rod motor and the right longitudinal telescopic rod motor respectively according to the moving path of the right limit block 24, thereby controlling the movement of the right limit block 24, so that the left limit block 20 and the right limit block 24 limit the patient's head to prevent the patient's unconscious head movement from causing damage to the surgical site.

[0076] Example 3

[0077] Based on the same inventive idea, Figure 5 , Figure 5 The following is a flow chart of the intelligent head fixing method provided by the present invention, which is used to illustrate a specific embodiment of the intelligent head fixing method provided by the present invention, and is applied to any one of the improved intelligent head fixing protective beds in the above embodiments, including:

[0078] S101: The patient is located on the side of the bed away from the ground, and the patient's head is marked with positioning points, including a left positioning point and a right positioning point;

[0079] S102: The left mark point is located at the left initial position, and the right mark point is located at the right initial position;

[0080] S103: The processor stores the left initial position and the right initial position, and the processor sends a collection signal to the camera;

[0081] S104: The camera receives a collection signal, collects an image according to the collection signal, and sends the image to a processor;

[0082] S105: The processor determines the three-dimensional coordinates of the left positioning point and the three-dimensional coordinates of the right positioning point according to the image;

[0083] S106: The processor generates a moving path of the left marker point according to the three-dimensional coordinates of the left positioning point and the left initial position, and controls the left fixed component to drive the left marker point to move to the left positioning point; the processor generates a moving path of the right marker point according to the three-dimensional coordinates of the right positioning point and the right initial position, and controls the right fixed component to drive the right marker point to move to the right positioning point.

[0084] It should be noted that the left positioning point and the right positioning point can be directly marked on the patient's head with a red pen, or red positioning points can be made and pasted on the patient's head. This implementation does not make specific restrictions on this. This embodiment takes marking red positioning points on the patient's head with a pen as an example.

[0085] It can be understood that in step S105, the processor determines the three-dimensional coordinates of the left positioning point and the three-dimensional coordinates of the right positioning point according to the image, including: the processor determines the two-dimensional coordinates of the left positioning point and the two-dimensional coordinates of the right positioning point according to the image; determines the three-dimensional coordinates of the left positioning point in the camera coordinate system according to the two-dimensional coordinates of the left positioning point and the calibration parameters of the camera, and determines the three-dimensional coordinates of the right positioning point in the camera coordinate system according to the two-dimensional coordinates of the right positioning point and the calibration parameters of the camera; converts the three-dimensional coordinates of the left positioning point in the camera coordinate system to the spatial coordinate system to obtain the three-dimensional coordinates of the left positioning point, and converts the three-dimensional coordinates of the right positioning point in the camera coordinate system to the spatial coordinate system to obtain the three-dimensional coordinates of the right positioning point. The processor determines the two-dimensional coordinates of the left positioning point and the two-dimensional coordinates of the right positioning point according to the image specifically as follows: the processor uses a target detection model to obtain the two-dimensional coordinates of the left positioning point and the right positioning point in the image. The target detection model can use an existing neural network model. The target detection model has been trained before the improved intelligent fixed head protective bed leaves the factory and can be directly used to test the red positioning point.

[0086] In step S106, the processor determines whether the distance between the left positioning point and the left initial position along the horizontal direction is smaller than the distance between the right positioning point and the left initial position along the horizontal direction. If so, the left positioning point is close to the left fixed component and the right positioning point is close to the right fixed component. The processor controls the left fixed component to drive the left marking point to move to the left positioning point, and controls the right fixed component to drive the right marking point to move to the right positioning point, thereby limiting the patient's head and preventing damage to the surgical site due to unconscious head movement.

[0087] It can be seen from the above embodiments that the improved intelligent head-fixing protective bed and the intelligent head-fixing method provided by the present invention achieve at least the following beneficial effects:

[0088] The improved intelligent head-fixing protective bed and the intelligent head-fixing method provided by the present invention include a fixing system, a camera and a processor; the fixing system includes a left fixing component and a right fixing component, the left fixing component includes a left sliding table, a left vertical telescopic rod, a left longitudinal telescopic rod and a left limit block; the right fixing component includes a right sliding table, a right vertical telescopic rod, a right longitudinal telescopic rod and a right limit block. The camera captures images and transmits them to the processor, which determines the moving paths of the left limit block and the right limit block based on the images. The processor controls the left slide table to drive the left limit block to move in the horizontal direction, controls the left vertical telescopic rod to drive the left limit block to move in the direction perpendicular to the ground, and controls the left longitudinal telescopic rod to drive the left limit block to move in the longitudinal direction based on the moving path of the left limit block; the processor controls the right slide table to drive the right limit block to move in the horizontal direction, controls the right vertical telescopic rod to drive the right limit block to move in the direction perpendicular to the ground, and controls the right longitudinal telescopic rod to drive the right limit block to move in the longitudinal direction based on the moving path of the right limit block, so that the left limit block and the right limit block limit the patient's head to avoid damage to the surgical site caused by unconscious head movement of the patient, and the positions of the left limit block and the right limit block can flexibly plan the moving paths according to the surgical site, which is easy to use and will not increase the workload of medical staff.
