Description

Technical Field

[0001] The present application relates to the field of medical equipment, and in particular to a head position monitoring device and method. Background Art

[0002] Pneumatic retinopexy is a low-cost, minimally invasive, and rapid-recovery treatment for rhegmatogenous retinal detachment. It works by injecting a gas bubble into the vitreous cavity of the eye to press against the retinal tear, thereby sealing it. Because the vitreous cavity is a spherical cavity, the gas bubble must reach the site of the retinal tear to accurately press against it. Therefore, for a period of time after surgery, the patient must maintain a certain head position to ensure that the gas bubble injected into the vitreous cavity accurately presses against the retinal tear.

[0003] In the prior art, in order to avoid adverse consequences, a head position monitoring device is used to monitor the patient's head position changes after surgery. If the head position deviates beyond a certain degree, an alarm is issued to promptly inform medical staff so that they can adjust the patient's head position in time to avoid the patient being in a deviated head position for a long time. However, the inventors of this application have found that:

[0004] Existing head position monitoring devices can only indicate head position deviation, but cannot guide patients on how to adjust it. Medical staff still need to pay attention and adjust it at all times. Therefore, the head position monitoring device can only be used during hospitalization in the hospital and cannot be used by patients at home after discharge, thereby increasing the patient's hospitalization costs and not reducing the use of medical resources.

[0073] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0074] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0075] In an exemplary embodiment, Figure 1 As shown, a head position monitoring device is provided, comprising a head position information monitoring device 1, a first terminal device 2 and a processing module 3.

[0076] The head position information monitoring device 1 is used to monitor the real-time head position information of a target patient, where the head position information includes an X-axis rotation angle and a Y-axis rotation angle.

[0077] In the present embodiment, the target patient refers to a patient undergoing pneumatic retinopexy surgery who requires real-time head position monitoring. The Z-axis represents the gravity axis, and the Z-axis rotation angle refers to the angle of rotation about the gravity axis. The Y-axis represents the axis perpendicular to the target patient's face, and the Y-axis rotation angle refers to the angle of rotation about the axis perpendicular to the target patient's face. The X-axis represents the pitch axis, and the X-axis rotation angle refers to the angle of rotation about the pitch axis.

[0078] The first terminal device 2 is used to send the acquired real-time head position information of the target patient to the processing module 3, and display the received head position adjustment prompt to the target patient; wherein the head position adjustment prompt includes an X-axis head position adjustment prompt and / or a Y-axis head position adjustment prompt.

[0079] In the embodiment of the present application, there is no specific limitation on the form in which the first terminal device 2 displays the received head position adjustment prompt to the target patient, and it can be set according to actual needs, for example, Figure 2 The terminal interface shown is displayed.

[0080] The processing module 3 is configured to calculate, based on the head position information of the target patient's real-time head position, a rotation offset and an offset direction of the target patient's real-time head position relative to the target head position; wherein the offset direction includes an X-axis offset direction and / or a Y-axis offset direction, and the rotation offset includes an X-axis rotation angle offset and / or a Y-axis rotation angle offset;

[0081] Generate head position adjustment prompts based on the rotation offset and offset direction.

[0082] In the embodiment of the present application, the processing module 3 is not specifically limited and can be set according to actual needs. For example, a processor is used. The target head position is the head position of the target patient when the target bubble accurately presses against the retinal tear (so that the target bubble reaches the position of the retinal tear). The target bubble is a bubble formed by injecting sterilized air or inert gas into the eyeball of the target patient during pneumatic retinopexy. If the real-time head position of the target patient is only rotated in the X-axis or Y-axis compared to the target head position, the offset direction includes the X-axis offset direction or the Y-axis offset direction, and the rotation offset includes the X-axis rotation angle offset or the Y-axis rotation angle offset. If the real-time head position of the target patient is rotated in both the X-axis and the Y-axis compared to the target head position, the offset direction includes the X-axis offset direction and the Y-axis offset direction, and the rotation offset includes the X-axis rotation angle offset and the Y-axis rotation angle offset.

[0083] If the target patient's real-time head position is only rotated along the X-axis or Y-axis compared to the target head position, the head position adjustment prompt includes the X-axis head position adjustment prompt or the Y-axis head position adjustment prompt. If the target patient's real-time head position is rotated along both the X-axis and Y-axis compared to the target head position, the head position adjustment prompt includes the X-axis head position adjustment prompt and the Y-axis head position adjustment prompt.

[0084] The first terminal device 2 monitors the X-axis rotation angle and Y-axis rotation angle of the real-time head position of the target patient according to the head position information monitoring device 1, and the first terminal device 2 sends the acquired real-time head position information of the target patient to the processing module 3, and the processing module 3 calculates the rotation offset (X-axis rotation angle offset and / or Y-axis rotation angle offset) and offset direction (X-axis offset direction and / or Y-axis offset direction) of the real-time head position of the target patient compared with the target head position, and generates a head position adjustment prompt (X-axis head position adjustment prompt and / or Y-axis head position adjustment prompt) according to the rotation offset and offset direction, and The head position adjustment prompt is displayed to the target patient through the first terminal device 2. When the head position shifts, the medical staff does not need to adjust the head position of the target patient. Instead, the target patient can adjust the head position to the target head position according to the head position adjustment prompt. Therefore, the target patient can use the head position monitoring device of the present application to monitor the head position at home after being discharged from the hospital to assist in postoperative recovery of pneumatic retinopexy, instead of having to be hospitalized in the hospital. This can effectively shorten the hospitalization time of the target patient, thereby reducing the hospitalization cost of the target patient, and solves the problem that the existing head position monitoring device can only be used during hospitalization in the hospital, thereby increasing the patient's hospitalization cost.

[0085] In another exemplary embodiment of the present application, the processing module 3 is further configured to:

[0086] The rotation offset is calculated using the following formula:

[0087] X-axis rotation offset = first rotation angle - second rotation angle;

[0088] Y-axis rotation offset = third rotation angle - fourth rotation angle;

[0089] Among them, the first rotation angle is the X-axis rotation angle of the target patient's real-time head position, the second rotation angle is the X-axis rotation angle of the target head position; the third rotation angle is the Y-axis rotation angle of the target patient's real-time head position, and the fourth rotation angle is the Y-axis rotation angle of the target head position.

[0090] In another exemplary embodiment of the present application, the processing module 3 is further configured to:

[0091] Follow these steps to determine the offset direction:

[0092] If the first rotation angle and the second rotation angle have opposite rotation directions, or if the first rotation angle and the second rotation angle have the same rotation direction and the X-axis rotation offset is a negative value, then the X-axis offset direction is opposite to the X-axis head position direction of the target head position; otherwise, the X-axis offset direction is the same as the X-axis head position direction of the target head position;

[0093] If the rotation directions of the third rotation angle and the fourth rotation angle are opposite, or if the rotation directions of the third rotation angle and the fourth rotation angle are the same and the Y-axis rotation offset is a negative value, then the Y-axis offset direction is opposite to the Y-axis head position direction of the target head position; otherwise, the Y-axis offset direction is the same as the Y-axis head position direction of the target head position.

[0094] In the embodiment of the present application, the rotation direction includes counterclockwise or clockwise. The rotation direction corresponds to the positive or negative of the rotation angle. For example, if the rotation is counterclockwise when viewed along the positive direction of the X-axis or Y-axis, the X-axis rotation angle or the Y-axis rotation angle is considered to be a positive value; conversely, if the rotation is clockwise when viewed along the positive direction of the X-axis or Y-axis, the X-axis rotation angle or the Y-axis rotation angle is considered to be a negative value. The X-axis head position direction of the target head position includes downward or upward, and the Y-axis head position direction includes left or right, which is specifically determined according to the rotation direction of the X-axis rotation angle and the Y-axis rotation angle of the target head position, that is, the positive or negative of the X-axis rotation angle and the Y-axis rotation angle. For example, if the X-axis rotation angle is a negative value, the X-axis head position direction of the target head position is downward, and if the X-axis rotation angle is a positive value (which may include the case where the X-axis rotation angle is zero), the X-axis head position direction of the target head position is upward. If the Y-axis rotation angle is a negative value, the Y-axis head position direction of the target head position is leftward. If the Y-axis rotation angle is a positive value (including the case where the Y-axis rotation angle is zero), the Y-axis head position direction of the target head position is rightward.

[0095] In another exemplary embodiment of the present application, the processing module 3 is further configured to:

[0096] If the X-axis head position adjustment amount is greater than a set first threshold, an X-axis head position adjustment prompt is generated according to the X-axis head position adjustment direction and the X-axis head position adjustment amount; wherein the X-axis head position adjustment direction is the opposite direction of the X-axis offset direction, and the X-axis head position adjustment amount is the absolute value of the X-axis rotation offset;

[0097] If the Y-axis head position adjustment amount is greater than a set second threshold, a Y-axis head position adjustment prompt is generated according to the Y-axis head position adjustment direction and the Y-axis head position adjustment amount; wherein the Y-axis head position adjustment direction is the opposite direction of the Y-axis offset direction, and the Y-axis head position adjustment amount is the absolute value of the Y-axis rotation offset.

[0098] In the embodiments of the present application, the first threshold and the second threshold are not specifically limited and can be set according to actual needs. Specifically, the first threshold and the second threshold can be set to be no greater than the maximum X-axis rotation offset and the maximum Y-axis rotation offset that are allowed to deviate from the target bubble without affecting the postoperative recovery effect. The maximum X-axis rotation offset and the maximum Y-axis rotation offset can be measured through simulation.

[0099] The X-axis head adjustment prompt is used to prompt the target patient to adjust the head position along the X-axis. The adjustment angle is the amount of the X-axis head adjustment. The Y-axis head adjustment prompt is used to prompt the target patient to adjust the head position along the Y-axis. The adjustment angle is the amount of the Y-axis head adjustment. For example, the head adjustment prompt reminds the target patient to lean left 17 degrees (rotate 17 degrees to the left) or lower their head 18 degrees (rotate 18 degrees downward).

[0100] In another exemplary embodiment of the present application, the processing module 3 is further configured to:

[0101] If the X-axis head position adjustment amount is greater than the set first threshold, or the Y-axis head position adjustment amount is greater than the set second threshold, an alarm is issued to remind the target patient that the head position deviates, so that the target patient can adjust the head position in time according to the head position adjustment prompt.

[0102] In another exemplary embodiment of the present application, the head position information further includes a Z-axis rotation angle, and the processing module 3 is further configured to:

[0103] According to the head position information of the target head position, an overlapping retinal break model and a target bubble model are constructed at the top position inside the eyeball in the constructed three-dimensional eyeball model to obtain the target three-dimensional model.

[0104] In this embodiment, when the target patient is in the target head position, the target bubble accurately presses against the retinal tear, resulting in the constructed retinal tear model and the target bubble model overlapping. Constructing the overlapping retinal tear and target bubble models at the top of the eyeball is intended to more intuitively demonstrate the positional relationship between the retinal tear and the target bubble in the 3D eyeball model.

[0105] In another exemplary embodiment of the present application, the processing module 3 is further configured to:

[0106] According to the mapping relationship between the head position information of the target head position and the three-dimensional coordinates of the target bubble model in the target three-dimensional model, the real-time three-dimensional coordinates of the target bubble are determined by the real-time head position information of the target patient;

[0107] According to the real-time three-dimensional coordinates of the target bubble, the position of the target bubble model is updated in the target three-dimensional model to obtain a real-time three-dimensional model.

[0108] In an embodiment of the present application, a three-dimensional model of the eyeball is drawn using a three-dimensional model drawing method, and a target bubble model and a retinal tear model are constructed in the three-dimensional eyeball model. The three-dimensional model drawing method can be WEBGL technology, and the three-dimensional eyeball model is loaded via an FBX file. The rotation angles in the target three-dimensional model and the real-time three-dimensional model are drawn in the order of Z-axis rotation angle, Y-axis rotation angle, and X-axis rotation angle. The real-time three-dimensional model can display the positional relationship between the target bubble and the retinal tear in the eyeball of the target patient in the real-time head position, so that the target patient can adjust the head position in a timely manner, and the head position adjustment is terminated when the target bubble model and the retinal tear model overlap in the real-time three-dimensional model.

[0109] Accordingly, the first terminal device 2 is further configured to:

[0110] The real-time three-dimensional model is displayed to the target patient so that the target patient adjusts the real-time head position to the target head position according to the head position adjustment prompt and the positional relationship between the target bubble model and the retinal break model in the real-time three-dimensional model.

[0111] In an embodiment of the present application, when the target patient has not adjusted the real-time head position to the target head position, the target bubble model and the retinal tear model in the real-time three-dimensional model are misaligned. As the target patient adjusts the head position according to the head position adjustment prompt, the distance between the target bubble model and the retinal tear model in the real-time three-dimensional model gradually decreases. When the target bubble model and the retinal tear model overlap in the real-time three-dimensional model, it means that the head position has been adjusted to the target head position, and the target patient can stop adjusting the head position at this time. There is no specific limitation on the display form of the real-time three-dimensional model, and it can be set according to actual needs. For example, by Figure 2 The display interface shown displays a real-time three-dimensional model to the target patient.

[0112] In another exemplary embodiment of the present application, the first terminal device 2 is a mobile terminal.

[0113] In the embodiments of the present application, a mobile terminal refers to an electronic device that can be conveniently carried and used for communication, information processing, and internet access at any time and place. This includes, but is not limited to, smartphones, tablet computers, and portable wearable devices. Portable wearable devices may include smart watches, smart bracelets, head-mounted devices, and the like. The mobile terminal can be connected to the head position information monitoring device 1 via Bluetooth.

[0114] In another exemplary embodiment of the present application, the head position monitoring device further includes:

[0115] The second terminal device 4 is used to obtain input from medical staff before monitoring the real-time head position information of the target patient;

[0116] The data storage module 5 is used to store the target head position and real-time head position information of the target patient.

[0117] In the embodiment of the present application, the input of the medical staff refers to the input of the medical staff at the initial moment indicating that the head position of the target patient has been adjusted to the target head position. There is no limitation on the method of obtaining the input of the medical staff, and it can be set according to actual needs. For example, by Figure 3 The terminal interface shown obtains input from medical staff.

[0118] The second terminal device 3 can be, but is not limited to, various desktop computers, laptops, smart phones, tablet computers and portable wearable devices. The portable wearable devices can be smart watches, smart bracelets, etc.

[0119] Accordingly, the processing module 3 is further configured to:

[0120] A first feedback signal is generated according to the input of the medical staff, and the first feedback signal is sent to the first terminal device 2.

[0121] The first terminal device 2 is further configured to:

[0122] Before monitoring the real-time head position information of the target patient, the head position information of the target patient is monitored according to the received first feedback signal, the head position information of the target head position is obtained, and the head position information of the target head position is sent to the data storage module 5 .

[0123] In another exemplary embodiment of the present application, the second terminal device 4 is further configured to:

[0124] The management data storage module 5 stores the target patient's wearing record of the head position information monitoring device 1 ; wherein the wearing record includes each wearing time and the head position information and rotation offset of each head position under each wearing time.

[0163] In another exemplary embodiment of the present application, the processing module 3 further includes a head position adjustment amount determining device 16, which includes a first absolute value circuit 17, a second absolute value circuit 18, a third comparator 19 and a fourth comparator 20. Figure 11 As shown. Among them:

[0164] The input end of the first absolute value circuit 17 is connected to the output end of the first subtractor 8-1, the output end of the first absolute value circuit 17 is connected to the first input end of the third comparator 19 and the processor unit, the second input end of the third comparator 19 is connected to the first threshold voltage, and the third comparator 19 is used to: if the X-axis head position adjustment amount is greater than the preset first threshold voltage, then output the fifth level and send it to the processor unit; otherwise, output the sixth level and send it to the processor unit; wherein, the first absolute value circuit 17 is used to: perform an absolute value operation on the X-axis rotation offset, and the output of the output end of the first absolute value circuit 17 is the X-axis head position adjustment amount.

[0165] In this embodiment of the present application, if the processor unit receives the fifth level, the processor unit generates an X-axis head position adjustment prompt based on the real-time X-axis head position offset direction and X-axis head position adjustment amount, and transmits the result to the first terminal device 2 for display. If the processor unit receives the sixth level, no X-axis head position adjustment prompt needs to be generated.

If the processor unit receives the eighth level, no Y-axis head position adjustment prompt needs to be generated. The second threshold voltage is set based on actual needs and is not specifically limited here.

[0168] In another exemplary embodiment of the present application, the first absolute value circuit 17 and the second absolute value circuit 18 have the same structure, both including an inverter 21, a non-inverting proportional amplifier 22 and a multiplier 23. Figure 12 shown.

[0169] in:

[0170] The input end of the inverter 21 is connected to the output end of the first subtractor 8-1 or the output end of the second subtractor 8-2, the output end of the inverter 21 is connected to the inverting input end of the in-phase proportional amplifier 22, the in-phase input end of the in-phase proportional amplifier 22 is grounded, and the output end of the in-phase proportional amplifier 22 and the output end of the inverter 21 are connected to the input end of the multiplier 23; wherein, the in-phase proportional amplifier 22 is used to perform in-phase amplification on the output of the inverter 21, and the output end of the multiplier 23 is the X-axis head position adjustment amount or the Y-axis head position adjustment amount.

[0171] In the embodiment of the present application, if the input of the inverter 21 is negative, the output of the non-inverting proportional amplifier 22 is -1, which is multiplied by the multiplier 23 and output as the absolute value of the input of the inverter 21. If the input of the inverter 21 is positive, the output of the non-inverting proportional amplifier 22 is 1, which is multiplied by the multiplier 23 and output as the input of the inverter 21.

[0172] In an exemplary embodiment, Figure 13 As shown, a head position monitoring method is provided, including the following steps 101 to 104. In which:

[0173] Step 101 : Monitor the real-time head position information of a target patient through a head position information monitoring device 1 ; wherein the head position information includes an X-axis rotation angle and a Y-axis rotation angle.

[0174] In the embodiment of the present application, when monitoring the real-time head position of a target patient using the head position monitoring device 1, the head position monitoring device 1 is fixed to the center of the target patient's forehead. The target patient refers to a patient undergoing pneumatic retinopexy surgery whose real-time head position needs to be monitored. The Y-axis is perpendicular to the target patient's face, and the Y-axis rotation angle refers to the angle of rotation around the axis perpendicular to the target patient's face. The X-axis is the pitch axis, and the X-axis rotation angle refers to the angle of rotation around the pitch axis.

[0175] Step 102: Calculate the rotation offset and offset direction of the target patient's real-time head position relative to the target head position based on the target patient's real-time head position information; wherein the offset direction includes an X-axis offset direction and / or a Y-axis offset direction, and the rotation offset includes an X-axis rotation angle offset and / or a Y-axis rotation angle offset.

[0176] In an embodiment of the present application, if the target patient's real-time head position is only rotationally offset along the X-axis or the Y-axis compared to the target head position, the offset direction includes the X-axis offset direction or the Y-axis offset direction, and the rotation offset includes the X-axis rotation angle offset or the Y-axis rotation angle offset. If the target patient's real-time head position is rotationally offset along both the X-axis and the Y-axis compared to the target head position, the offset direction includes the X-axis offset direction and the Y-axis offset direction, and the rotation offset includes the X-axis rotation angle offset and the Y-axis rotation angle offset.

[0177] Step 103 : Generate a head position adjustment prompt according to the rotation offset and the offset direction. The head position adjustment prompt includes an X-axis head position adjustment prompt and / or a Y-axis head position adjustment prompt.

[0178] In the embodiment of the present application, if the target patient's real-time head position is only offset in rotation angle on the X-axis or Y-axis compared to the target head position, the head position adjustment prompt includes an X-axis head position adjustment prompt or a Y-axis head position adjustment prompt. If the target patient's real-time head position is offset in rotation angle on both the X-axis and Y-axis compared to the target head position, the head position adjustment prompt includes an X-axis head position adjustment prompt and a Y-axis head position adjustment prompt.

[0179] Step 104: Display a head position adjustment prompt to the target patient.

[0180] Implement the above-mentioned steps 101 to 104, monitor the X-axis rotation angle and Y-axis rotation angle of the real-time head position of the target patient according to the head position information monitoring device 1, calculate the rotation offset (X-axis rotation angle offset and / or Y-axis rotation angle offset) and offset direction (X-axis offset direction and / or Y-axis offset direction) of the real-time head position of the target patient compared to the target head position, generate a head position adjustment prompt (X-axis head position adjustment prompt and / or Y-axis head position adjustment prompt) according to the rotation offset and the offset direction, and display the head position adjustment prompt to the target patient. When the head position is offset, the medical staff does not need to adjust the head position of the target patient, but the target patient can adjust the head position to the target head position according to the head position adjustment prompt. Therefore, the target patient can use the head position monitoring device of the present application to monitor the head position at home after being discharged from the hospital to assist in postoperative recovery of pneumatic retinopexy, instead of having to be hospitalized in the hospital. This can effectively shorten the target patient's hospitalization time, thereby reducing the target patient's hospitalization expenses, and solve the problem that the existing head position monitoring device can only be used in the hospital, thereby increasing the patient's hospitalization expenses.

[0181] In another exemplary embodiment of the present application, the above step 102 includes the following steps 301 to 302. Among them:

[0182] Step 301: Calculate the rotation offset according to the following formula:

[0183] X-axis rotation offset = first rotation angle - second rotation angle;

[0184] Y-axis rotation offset = third rotation angle - fourth rotation angle;

[0185] Among them, the first rotation angle is the X-axis rotation angle of the target patient's real-time head position, the second rotation angle is the X-axis rotation angle of the target head position; the third rotation angle is the Y-axis rotation angle of the target patient's real-time head position, and the fourth rotation angle is the Y-axis rotation angle of the target head position.

[0186] Step 302: Determine the offset direction according to the following steps:

[0187] If the first rotation angle and the second rotation angle have opposite rotation directions, or if the first rotation angle and the second rotation angle have the same rotation direction and the X-axis rotation offset is a negative value, then the X-axis offset direction is opposite to the X-axis head position direction of the target head position; otherwise, the X-axis offset direction is the same as the X-axis head position direction of the target head position;

[0188] If the rotation directions of the third rotation angle and the fourth rotation angle are opposite, or if the rotation directions of the third rotation angle and the fourth rotation angle are the same and the Y-axis rotation offset is a negative value, then the Y-axis offset direction is opposite to the Y-axis head position direction of the target head position; otherwise, the Y-axis offset direction is the same as the Y-axis head position direction of the target head position.

[0189] In the embodiment of the present application, the rotation direction includes counterclockwise or clockwise. The rotation direction corresponds to the positive or negative value of the rotation angle. For example, if the rotation is counterclockwise when viewed along the positive direction of the X-axis, Y-axis or Z-axis, the X-axis rotation angle, Y-axis rotation angle or Z-axis rotation angle is considered to be positive; conversely, if the rotation is clockwise when viewed along the positive direction of the X-axis, Y-axis or Z-axis, the X-axis rotation angle, Y-axis rotation angle or Z-axis rotation angle is considered to be negative. The X-axis head position direction of the target head position includes downward or upward, and the Y-axis head position direction includes left or right, which is specifically determined according to the rotation direction of the X-axis rotation angle, Y-axis rotation angle and Z-axis rotation angle of the target head position, that is, the positive or negative value of the X-axis rotation angle, Y-axis rotation angle and Z-axis rotation angle. For example, if the X-axis rotation angle is negative, the X-axis head position direction of the target head position is downward, and if the X-axis rotation angle is positive (which may include the case where the X-axis rotation angle is zero), the X-axis head position direction of the target head position is upward. If the Y-axis rotation angle is a negative value, the Y-axis head position direction of the target head position is leftward. If the Y-axis rotation angle is a positive value (including the case where the Y-axis rotation angle is zero), the Y-axis head position direction of the target head position is rightward.

[0190] In another exemplary embodiment of the present application, the above step 103 includes:

[0191] If the X-axis head position adjustment amount is greater than a set first threshold, an X-axis head position adjustment prompt is generated according to the X-axis head position adjustment direction and the X-axis head position adjustment amount; wherein the X-axis head position adjustment direction is the opposite direction of the X-axis offset direction, and the X-axis head position adjustment amount is the absolute value of the X-axis rotation offset;

[0192] If the Y-axis head position adjustment amount is greater than a set second threshold, a Y-axis head position adjustment prompt is generated according to the Y-axis head position adjustment direction and the Y-axis head position adjustment amount; wherein the Y-axis head position adjustment direction is the opposite direction of the Y-axis offset direction, and the Y-axis head position adjustment amount is the absolute value of the Y-axis rotation offset.

[0193] In the embodiments of the present application, the first and second thresholds are not specifically defined and can be set based on actual needs. Specifically, the first and second thresholds can be set to be no greater than the maximum X-axis rotation offset and maximum Y-axis rotation offset of the target bubble that can be allowed to deviate without affecting postoperative recovery. The maximum X-axis rotation offset and maximum Y-axis rotation offset can be measured through simulation. The target bubble is formed in the eye of the target patient by injecting sterile air or inert gas during pneumatic retinopexy.

[0194] The X-axis head adjustment prompt is used to prompt the target patient to adjust the head position along the X-axis. The adjustment angle is the amount of the X-axis head adjustment. The Y-axis head adjustment prompt is used to prompt the target patient to adjust the head position along the Y-axis. The adjustment angle is the amount of the Y-axis head adjustment. For example, the head adjustment prompt reminds the target patient to lean left 17 degrees (rotate 17 degrees to the left) or lower their head 18 degrees (rotate 18 degrees downward).

[0195] In another exemplary embodiment of the present application, the head position monitoring method further includes:

[0196] If the X-axis head position adjustment amount is greater than the set first threshold, or the Y-axis head position adjustment amount is greater than the set second threshold, an alarm is issued to remind the target patient that the head position deviates, so that the target patient can adjust the head position in time according to the head position adjustment prompt.

[0197] In another exemplary embodiment of the present application, in step 101, the head position information further includes a Z-axis rotation angle.

[0198] In the embodiment of the present application, the Z-axis is the gravity axis, and the Z-axis rotation angle refers to the angle of rotation around the gravity axis.

[0199] The above-mentioned head position monitoring method further includes:

[0200] Step 401 : constructing an overlapping retinal break model and a target bubble model at the top position inside the eyeball in the constructed three-dimensional eyeball model according to the head position information of the target head position, thereby obtaining a target three-dimensional model.

[0201] In this embodiment, when the target patient is in the target head position, the target bubble accurately presses against the retinal tear, resulting in the constructed retinal tear model and the target bubble model overlapping. Constructing the overlapping retinal tear and target bubble models at the top of the eyeball is intended to more intuitively demonstrate the positional relationship between the retinal tear and the target bubble in the 3D eyeball model.

[0202] In another exemplary embodiment of the present application, the head position monitoring method further includes the following steps 501 to 503.

[0203] Step 501 : Determine the real-time 3D coordinates of the target bubble based on the real-time head position information of the target patient according to the mapping relationship between the target head position information and the 3D coordinates of the target bubble model in the target 3D model.

[0204] Step 502 : updating the position of the target bubble model in the target three-dimensional model according to the real-time three-dimensional coordinates of the target bubble to obtain a real-time three-dimensional model.

[0205] In an embodiment of the present application, a three-dimensional model of the eyeball is drawn using a three-dimensional model drawing method, and a target bubble model and a retinal tear model are constructed in the three-dimensional eyeball model. The three-dimensional model drawing method can be WEBGL technology, and the three-dimensional eyeball model is loaded via an FBX file. The rotation angles in the target three-dimensional model and the real-time three-dimensional model are drawn in the order of Z-axis rotation angle, Y-axis rotation angle, and X-axis rotation angle. The real-time three-dimensional model can display the positional relationship between the target bubble and the retinal tear in the eyeball of the target patient in the real-time head position, so that the target patient can adjust the head position in a timely manner, and the head position adjustment is terminated when the target bubble model and the retinal tear model overlap in the real-time three-dimensional model.

[0206] Step 503 : Display the real-time 3D model to the target patient, so that the target patient adjusts the real-time head position to the target head position according to the head position adjustment prompt and the positional relationship between the target bubble model and the retinal break model in the real-time 3D model.

[0207] In the embodiment of the present application, when the target patient has not adjusted the real-time head position to the target head position, the target bubble model and the retinal tear model in the real-time three-dimensional model are misaligned. As the target patient adjusts the head position according to the head position adjustment prompt, the distance between the target bubble model and the retinal tear model in the real-time three-dimensional model gradually decreases.
