Description

TECHNICAL FIELD The present invention relates to an intraoperative patient management system that predicts the possibility of developing various complications during or after a patient's surgery and alerts medical personnel.

Conventionally, during an operation, the patient is placed on the table of the operating table in the same posture, which causes problems such as the development of pressure ulcers (bedsores). This pressure ulcer develops when pressure is applied to the body surface of a specific part of the patient for a long time, or when frictional force (shear force) is applied to the body surface of the patient's specific part. This frictional force is generated when the skin on a particular surface of the body is dragged as the patient is moved over the table.

To reduce pressure ulcer development, patients should be repositioned regularly (e.g., every two hours), and when the patient is moved, the frictional force (shear force) on the skin should be minimized. It is generally recommended that In this way, medical staff (staff involved in surgery) respond to the problem of pressure ulcer development by appropriately adjusting the patient's body position (posture) before and during surgery. However, there is no specific index (standard) for adjusting the patient's body position, and there is no choice but to rely on the experience and intuition of the medical staff.

For example, Patent Document 1 discloses an operating device for an operating table for a user to operate the movement of the table of a robotic operating table in which a table for placing a patient is moved by an articulated robot arm, wherein the table is operated by the user. and a display unit configured to display the elapsed time in the tilted posture when the table is tilted by the articulated robot arm according to the movement instruction. Disclosed is an operating table operating device comprising:

JP 2019-209191 A

In the operating device for an operating table according to Patent Document 1 described above, a medical worker who is operating the operating device must prevent a patient placed on a table from being held in the same posture for a long time in an inclined posture. Therefore, even when the table is tilted and the patient is tilted, the onset and aggravation of pressure ulcers (bedsores) in the patient can be suppressed. However, in the operating device for an operating table according to Patent Document 1, even if the medical staff can be careful not to keep the patient in the same posture for a long time in a tilted posture, as described above, pressure ulcers may occur. It is impossible to solve the problem that there is no specific guideline for adjusting the patient's body position (posture) in order to prevent the problem of onset, and that the experience and intuition of the medical staff must be relied upon.

In addition, in the above explanation, among the various complications related to the postoperative position during surgery, the problems related to pressure ulcers that may develop during or after surgery were explained, but various complications related to the postoperative position during surgery have been explained. In addition to pressure ulcers, other diseases include peripheral neuropathy, perioperative visual impairment, respiratory system disorders, and circulatory system disorders (e.g., hypotension). It is necessary to understand the causes of these complications and take appropriate preventive measures. For this reason, it is necessary to appropriately inform healthcare professionals in real time of the possibility of intraoperative or postoperative complications predicted from the position of the patient during surgery, and to appropriately prevent such complications. important.

As shown in FIG. 1, the table position detection unit 4 is electrically connected to the recording unit 37 of the onset prediction unit 6 via communication means.

As shown in FIGS. 1 and 2 , the body pressure detection means 5 is composed of a body pressure distribution detection sheet material 34 . The body pressure distribution detection sheet material 34 is detachably attached to the upper surface of the mattress 25 of the operating table 12 . The body pressure distribution detection sheet material 34 can visualize the patient's body pressure distribution. The body pressure distribution detection sheet material 34 is electrically connected to the recording unit 37 of the onset predicting means 6 by communication means. As shown in FIG. 1, the onset prediction means 6 detects past position data based on position information obtained from the table position detection unit 4 and past body pressure information based on body pressure information obtained from the body pressure detection means 5. Prediction for predicting the probability of occurrence of intraoperative or postoperative complications based on the recording unit 37 in which data is accumulated, the position information obtained from the table position detection unit 4, and the body pressure information obtained from the body pressure detection means 5 and a determination unit 39 that determines whether or not the probability of occurrence of intraoperative or postoperative complications predicted by the prediction unit 38 is high.

The recording unit 37 accumulates position data based on position information obtained from the table position detection unit 4 and body pressure data based on body pressure information obtained from the body pressure detection unit 5 for each past surgery. Into the recording unit 37, physical information such as the patient's gender, age, weight, etc., and personal data such as the presence or absence of an underlying disease, including the surgical procedure, are input for each operation. In the recording unit 37, personal data, position data, and body pressure data are accumulated for each operation in the past. , is input in association with the personal data, position data and body pressure data recorded at that time. For example, if the complication that has developed is a pressure ulcer, enter "pressure ulcer" and the body part where the pressure ulcer developed, for example, "around the back and sacrum", and record it.

As shown in FIG. 1, the recording unit 37 is electrically connected via communication means to a biological information acquisition device 42 that acquires the patient's biological information (vital signs). is recorded. The recording unit 37 is electrically connected to the imaging camera 46 (intraoperative imaging means 9) described later via communication means, and records images (moving images) obtained from the intraoperative imaging camera 46. be done. As a result, in the recording unit 37 of the onset prediction means 6, for each past surgery, personal data, position data of the table 15, body pressure data, intraoperative video, patient's biological information, and disease name of complications (intraoperative or (limited to postoperative complications) are accumulated as a group of comprehensive data. Note that the recording unit 37 is electrically connected via communication means to a personal computer 44 or the like placed in a room outside the operating room, such as a doctor's waiting room, a nurse's station, an educational facility, or the like. Note that the recording unit 37 may be electrically connected to a personal computer or the like owned by a doctor via communication means.

Based on the position information obtained from the table position detection unit 4 and the body pressure information obtained from the body pressure detection means 5, the prediction unit 38 predicts the possibility of intraoperative or postoperative complications (onset probability) is predicted and output. Specifically, position information obtained from the table position detection unit 4 and body pressure information obtained from the body pressure detection unit 5 are input to the prediction unit 38 via the recording unit 38 during the surgery. Then, the prediction unit 38 compares the personal data, the positional information and the body pressure information obtained from the recording unit 38 during the surgery with the large number of comprehensive data accumulated in the recording unit 37, and judges complications. predict and output the onset probability of (for example, the onset probability is displayed as a percentage (%)). The prediction unit 38 employs, for example, a method of predictive analysis by AI (artificial intelligence). Predictive analysis is one of data analysis methods that predicts future results from past performance data using statistical algorithms and machine learning.

In addition to prediction analysis by AI, the prediction unit 38 detects that the patient has been in the same posture for a predetermined time, for example, two hours or more, based on position information obtained from the table position detection unit 4 during surgery. A predictive criterion may be employed, such as a 70% probability of developing a complication. Further, in the prediction unit 38, based on the positional information obtained from the table position detection unit 4 during surgery, when the inclination angle of the patient's posture with respect to the horizontal plane reaches 30° or more, the probability of developing pressure ulcer complications is, for example, 50%. Assuming that there is, a prediction criterion such as a gradual increase in the onset probability as time elapses in that position may be employed. Furthermore, when the predicting unit 38 detects that the maximum body pressure has reached a predetermined value, for example, 32 mmHg or more, based on the body pressure information obtained from the body pressure detection unit 5, the probability of developing pressure ulcer complications is reduced to, for example, 50%. Assuming that , a prediction criterion such as a gradual increase in the onset probability as time elapses in that posture may be employed.

In short, the predicting unit 38 may predict the possibility of developing a complication (probability of occurrence) by setting a quantitative threshold value in advance as a prediction criterion, in addition to predictive analysis by AI. Further, the prediction unit 38 may be configured to make a prediction by making a comprehensive judgment based on the prediction based on the prediction analysis by AI and the prediction based on the prediction criteria set quantitatively in advance. Furthermore, the prediction unit 38 can be configured to analyze the result of the onset probability based on prediction analysis by AI and update the quantitatively set prediction criteria.

The determining unit 39 determines that the probability of developing complications has increased when the probability of developing complications predicted by the predicting unit 38 reaches a preset threshold value (for example, 70%). there is The determination section 39 is electrically connected to the warning generation section 8 . When the determination unit 39 of the onset prediction unit 6 determines that the probability of developing complications has increased, the warning generation unit 8 receives the signal from the determination unit 39 and transmits the signal to the onset probability display unit 7. Then, the onset probability display unit 7 displays a warning message and emits a warning sound.

The photographing camera 46 is arranged in the operating room at a position where the state of the entire operation centering on the patient can be photographed. The imaging camera 46 is electrically connected to the recording unit 37 of the onset predicting means 7 via communication means. Then, the image information (moving image) obtained from the imaging camera 46 during surgery is input to the recording unit 37 of the onset prediction means 6 via the communication means. When endoscopic surgery is employed, image information captured by an endoscope may also be input to the recording section 37 of the onset prediction means 6 via communication means. As a result, when endoscopic surgery is adopted, in addition to the image data captured by the imaging camera 46, the image data captured by the endoscope is stored in the recording unit 37 of the onset prediction means 6. will also be accumulated.

Specifically, various complications such as pressure ulcers, hypotension, peripheral neuropathy, perioperative visual impairment, and respiratory system disorders are sequentially displayed along the horizontal axis, and various complications are displayed along the vertical axis. The onset probability (0 to 100%) of each disease is output and displayed.

As shown in FIG. 1, the determination unit 39 of the onset prediction unit 6 is electrically connected to the warning generation unit 8 via communication means. The warning generation unit 8 is electrically connected to the onset probability display unit 7 via communication means.

An image (moving image) obtained from the imaging camera 46 is displayed in real time in the onset probability display section 7 (upper right region).

Next, the operation of the intraoperative patient management system 1 according to this embodiment will be described. In the intraoperative patient management system 1 according to the present embodiment, the personal data of the patient undergoing surgery, including the surgical procedure to be adopted, is input to the recording unit 37 of the onset prediction means 6 before surgery. Subsequently, the patient is placed on the table 15 of the operating table 12, and the medical staff operates the various operation buttons 30A to 30G of the operating table operating device 27 to operate the table 15, thereby allowing the patient to take the desired position against it. From this point on, the table position detector 4 detects the position of the table 15 over time, and the position information is input to the recording unit 37 of the onset prediction means 6 .

Almost at the same time, the pressure applied to the patient's body surface is detected over time by the body pressure distribution detection sheet material 34 , and the body pressure information is input to the recording unit 37 of the onset prediction means 6 . Almost at the same time, the imaging camera 46 takes an image of the whole operation centering on the patient, and the image is input to the recording unit 37 of the onset prediction means 6 . Almost at the same time, the patient's biological information obtained from the biological information acquisition device 42 is input to the recording unit 37 of the onset prediction means 6 . Then, the operation starts, and the position information of the table 15, the patient's body pressure information, the moving image during the operation, and the patient's biological information are recorded in the recording unit 37 of the onset prediction means 6 in the operation.

Subsequently, during surgery, personal data, position information obtained from the table position detection unit 4, and body pressure information obtained from the body pressure detection unit 5 are sent to the prediction unit 38 of the onset prediction unit 6 via the recording unit 37. In the prediction unit 38, based on the personal data, the position information obtained from the table position detection unit 4, and the body pressure information obtained from the body pressure detection unit 5, there is a possibility that intraoperative or postoperative complications will occur. Predict and output the sex (probability of onset). Since the specific method for predicting the possibility of developing complications has been described above, the description is omitted here. As a result, the onset probability display unit 7 displays the complications predicted by the prediction unit 38 of the onset prediction unit 6 and the onset probability thereof. Since the specific display content has also been described above, the description is omitted here.

Subsequently, when the determining unit 39 of the onset predicting means 6 determines that the probability of developing complications during or after surgery has increased, a signal is sent from the determining unit 39 to the warning generating unit 8 . Subsequently, the warning generation unit 8 transmits the signal to the onset probability display unit 7, and the onset probability display unit 7 displays a warning message and emits a warning sound. During the operation, the medical attendant can determine that there is a risk of developing complications during or after the operation from the warning message or warning sound displayed on the onset probability display section 7 .

Subsequently, the medical staff operates the various operation buttons 30A to 30G of the operating table operating device 27 to move the table 15 to change the patient's posture and change the patient's posture relative to the table 15. By implementing such actions, the probability of developing complications is reduced. Subsequently, after the medical staff confirms that the probability of developing the complication displayed on the onset probability display section 7 has decreased, the normal surgical procedure is resumed, and the operation is continued. The onset probability display unit 7 always displays the position information of the table 15, the patient's body pressure information, the video during surgery, and the patient's biological information. Since the specific contents of display on the onset probability display unit 7 have already been described above, the description thereof will be omitted here.

The recording unit 37 of the onset predicting means 6 is electrically connected via a communication means to a personal computer 44 or the like placed in a room outside the operating room, such as a doctor's waiting room, a nurse's station, an educational facility, or the like. Therefore, the medical staff can select an image corresponding to the planned surgical procedure from a large number of image data (image data obtained from the intraoperative photographing means 9) accumulated in the recording unit 37 of the onset prediction means 6 before surgery. The data can be referred to by the personal computer 44. FIG. Then, from the image data, for example, the patient's posture corresponding to the surgical procedure, the standing position of the medical staff (a plurality of staff members) during surgery, etc. corresponding to the surgical procedure can be grasped in advance. Moreover, since the image data obtained from the endoscope in the endoscopic surgery is also stored in the recording unit 37 of the onset prediction means 6, the medical staff can perform the planned endoscopic surgery before surgery. , the safest and quickest surgical method can be sufficiently studied in advance.
