In the following description and the accompanying drawings, components having the same functional configuration are designated by the same reference numerals, so that duplicate description will be omitted.

The hardware configuration of the surgical process recording system of this embodiment will be described with reference to FIG. The surgical process recording system includes a so-called computer, a surgical process recording server 100, a camera 110, and a medical device monitoring device 111.

In the surgical process recording server 100, a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, an interface 104, a storage unit 105, an input unit 106, and a display unit 107 are signaled by a bus 108. It is configured to be connected so that it can be sent and received. Further, the surgical process recording server 100 is connected to the camera 110 and the medical device monitoring device 111 so as to be able to send and receive signals via the interface 104. Here, "to be able to send and receive signals" is a state in which signals can be passed to each other or from one to the other, regardless of whether they are wired or wireless, electrically or optically.

The CPU 101 is a device that reads out a system program or the like stored in the ROM 102 and controls the operation of each component. The CPU 101 loads the program stored in the storage unit 105 and the data necessary for executing the program into the RAM 103 and executes the program. The storage unit 105 is a device for storing a program executed by the CPU 101 and data necessary for program execution, and specifically, a recording device such as an HDD (Hard Disk Drive) or SSD (Solid State Drive), an IC card, or the like. A device that reads and writes to a recording medium such as an SD card or DVD. Various data including data necessary for program execution may be transmitted and received from a network such as a LAN (Local Area Network). The RAM 103 stores a program executed by the CPU 101, the progress of arithmetic processing, and the like.

The display unit 107 is a device for displaying the result of program execution, and specifically, a liquid crystal display, a touch panel, or the like. The input unit 106 is an operation device in which the operator gives an operation instruction to the operation process recording server 100, specifically, a keyboard, a mouse, or the like. The mouse may be another pointing device such as a trackpad or trackball. When the display unit 107 is a touch panel, the touch panel also functions as the input unit 106. The interface 104 is for connecting an external device including a camera 110 and a medical device monitoring device 111 to a surgical process recording server 100.

The camera 110 is a device that captures videos of medical staff participating in surgery, such as surgeons, assistants, anesthesiologists, and nurses, and can capture the entire operating room as well as individual medical staff. good. Further, the camera 110 may record the voices of each medical staff. In addition, medical devices used in surgery, such as scalpels, may be imaged by the camera 110. Instead of shooting a moving image with the camera 110, each movement may be measured by an acceleration sensor or the like attached to a medical staff or a medical device.

The medical device monitoring device 111 is a device for monitoring medical devices used for surgery, such as a device for measuring biological data of a patient, an electric knife, and the like, and receives signals output from various devices. For example, data related to the patient's biological data such as heartbeat, blood pressure, and respiration, and electric power supplied to the electric knife are monitored.

That is, the camera 110 and the medical device monitoring device 111 acquire primary data indicating each operation of the medical staff participating in the surgery and the medical device used in the surgery, and transmit the primary data to the surgery process recording server 100 for processing. Operations include the distance traveled by medical staff and medical devices per unit time, and signals output from medical devices.

The functional block diagram of this embodiment will be described with reference to FIG. These functions may be configured by dedicated hardware using ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), or the like, or may be configured by software running on the CPU 101. .. In the following description, the case where each function is configured by software will be described. This embodiment includes an operation recording unit 201, a stagnation period extraction unit 202, and a time series data display unit 203. Hereinafter, each part will be described.

The operation recording unit 201 records each operation of the medical staff and the medical device in time series by using the operation data 200 which is the primary data acquired by the camera 110 and the medical device monitoring device 111. When the motion data 200 is a moving image of each medical staff, the motion recording unit 201 extracts the target medical staff from each frame image of the moving image, and based on the position of the target person in each frame image, Calculate the distance traveled by the subject per unit time. The target extracted from each frame image may be a part of the body of the medical staff, for example, a hand. By recording the movements of the surgeon's hands in chronological order, the procedure during surgery is converted into data. Each movement recorded in chronological order may be used to create a chart showing process transitions of medical staff and medical devices in the operating room.

An example of the process transition of the medical staff and the medical device in the operating room will be described with reference to FIGS. 3 and 4. Each medical staff and medical device are arranged on the vertical axis of FIG. 3, and the surgical phase is assigned to the horizontal axis, which is a common time axis. The surgical phase includes preparation, surgery, and post-process. A circle is added when the data meets a predetermined condition, and a line segment connecting the circles at both ends indicates one process. By displaying the process transition as shown in FIG. 3 on the display unit 107, the postoperative progress analysis can be performed for each process along a common time axis.

FIG. 4 is an example of associating the process transition shown in FIG. 3 with the position in the operating room. In the operating room, for example, when an outside nurse moves the positions of A and B in the non-clean field and the surgeon moves the positions of C and D in the clean field, A and B, C and D move in the corresponding steps. It will be added. In addition, it may be clearly stated whether each process is carried out in a clean field or a non-clean field. By displaying the process transition as shown in FIG. 4 on the display unit 107, the progress analysis for each process can be performed in correspondence with the position in the operating room. Returning to the description of FIG.

The stagnation period extraction unit 202 extracts the stagnation period, which is the period during which the operation of the medical staff or the medical device is stagnant, based on the time course of each operation recorded by the operation recording unit 201. For example, a period in which the amount of movement is smaller than a predetermined threshold value is extracted as a stagnation period. The threshold used for extracting the stagnation period is set for each object. Further, prior to the extraction of the stagnation period, a moving average process may be performed to reduce noise.

The time-series data display unit 203 assigns the stagnation period extracted by the stagnation period extraction unit 202 to the time-series data of each operation of the medical staff or the medical device and displays it on the display unit 107.

An example of the processing flow of this embodiment will be described with reference to FIG.

(S501)
The operation recording unit 201 acquires the operation data 200 from the camera 110 and the medical device monitoring device 111. The operation recording unit 201 records each operation of the medical staff and the medical device in time series using the operation data 200.

An example of the time-dependent change of each motion recorded in time series will be described with reference to FIG. In FIG. 6, as in FIG. 3, each medical staff and medical device are arranged on the vertical axis, and the horizontal axis is a common time axis. In addition, the amount of movement is shown in shades in the lines corresponding to each medical staff and medical device. The amount of movement is less in the black areas and more in the white areas.

(S502)
The stagnation period extraction unit 202 extracts the stagnation period for each of the medical staff and the medical device based on the change over time of each operation. A period in which the amount of motion is less than the threshold value, for example, a darker part shown in FIG. 6, is extracted as a stagnation period.

(S503)
The time-series data display unit 203 adds the stagnation period extracted by S502 to the time-series data of each operation of the medical staff and the medical device.

An example of the extracted stagnation period will be described with reference to FIG. 7. In FIG. 7, four stagnation periods extracted from the time course of each movement shown in FIG. 6 are shown by dotted squares. That is, from the left side, a period in which only the surgeon is stagnant, a period in which the instrument nurse and the outing nurse are stagnant, a period in which the surgeon, the assistant 2, and both nurses are stagnant, and a period in which all the nurses are stagnant are exemplified.

(S504)
The time-series data display unit 203 causes the display unit 107 to display the time-series data of each operation to which the stagnation period is given in S503. For example, the screen illustrated in FIG. 7 is displayed on the display unit 107. By displaying the time-series data of each movement with the stagnation period, it becomes clear in which period of the surgical process the stagnation occurred.

The importance may be given to each stagnation period. The importance may be calculated by the stagnation period extraction unit 202 based on the number of medical staff who are stagnant at the same time. For example, the number of people who are stagnant at the same time may be regarded as the importance of the stagnant period. Alternatively, as shown in the following equation, even if the importance f (w _n , t _n , p) is calculated by the stagnation period extraction unit 202 based on the work in charge of the medical staff, the length of stagnation time, and the phase of surgery. good.

Here, n is an index that identifies each medical staff, for example, 1 is a surgeon, 2 is an assistant, 3 is an anesthesiologist, 4 is an instrument nurse, 5 is an outside nurse, and so on. .. w _n is a coefficient assigned to the duties of each medical staff, for example, a high coefficient is assigned to the surgeon who operates the patient, and a low coefficient is assigned to the outpatient nurse who is not directly involved with the patient. t _n is the length of the stagnation period of each medical staff, and becomes more important when a plurality of medical staff are stagnation at the same time. p is a coefficient assigned to the phase of surgery, and a high coefficient is assigned during surgery and a low coefficient is assigned in the order of pre-surgery and post-surgery according to the burden on the patient.

An example of a stagnation period to which importance is given will be described with reference to FIG. In FIG. 8, the importance calculated by the equation 1 is given to the stagnation period illustrated in FIG. 7. By displaying the screen illustrated in FIG. 8 on the display unit 107, the priority order to be dealt with for the plurality of stagnation periods becomes clear.

Further, the time-series data display unit 203 may display the reason for each stagnation period on the display unit 107. The reason why each stagnation period occurs is determined by, for example, the stagnation period extraction unit 202 based on each operation before the target stagnation period. Further, the time-series data display unit 203 may display the reason for each stagnation period and the improvement measures for suppressing the stagnation on the display unit 107.

With reference to FIG. 9, an example of the stagnation period in which the reason for the stagnation and the improvement measures for suppressing the stagnation are given will be described. Two stagnation periods are shown in FIG. 9, and the stagnation situation, the reason for the stagnation, the importance, and the improvement measures are given to each stagnation period. In the stagnation period on the left side, the operation of the surgeon is stagnant, the reason for the stagnation is that the outside nurse is ordering the equipment, the importance of the stagnation period is 5, and the electric knife in advance as an improvement plan. It is shown that preparation is needed. In the stagnation period on the right side, although the surgeon and three others are stagnant, it is shown that the importance has been cleared to 0 because the surgery is ongoing because the electric scalpel is in operation. As in the example of the stagnation period on the right side, the importance calculated by the stagnation period extraction unit 202 may be corrected based on the operation of a medical device such as an electric knife. The improvement measure for suppressing the stagnation may be read from the table to which the reason and the improvement measure are associated.

With reference to FIG. 10, the reason why the stagnation period has occurred, the improvement measures, and an example of the table to which each operation is associated will be described. The table illustrated in FIG. 10 is created in advance in association with improvement measures and each operation for the reason for stagnation, and is stored in the storage unit 105. The stagnation period extraction unit 202 searches for each operation before the target stagnation period from the table exemplified in FIG. 10, extracts the stagnation reason corresponding to the searched operation as the reason for the stagnation period, and extracts it. Read out the corresponding improvement measures along with the reason for the stagnation. The time-series data display unit 203 causes the display unit 107 to display the stagnation reason and improvement measures read from the table by the stagnation period extraction unit 202.

The time-series data display unit 203 may display the recorded surgical process on the display unit 107 in comparison with the standard surgical process. By contrasting with the standard surgical process, it becomes clear where the delay is occurring in the recorded surgical process.

An example of a display comparing the recorded actual process with the standard surgical process will be described with reference to FIG. In FIG. 11, the lines of the actual process and the standard surgical process are added to the process transition illustrated in FIG. 3, and irregular events are added. Each checkpoint is indicated by a triangle in the rows of the actual process and the standard surgical process. By displaying the screen illustrated in FIG. 11 on the display unit 107, it becomes clear how much each checkpoint in the actual process is delayed with respect to the standard surgical process.

The irregular event shown in FIG. 11 may be the reason for the stagnation read from the table illustrated in FIG. Further, the time when each medical staff moves to a position different from the reference position may be the time when the irregular event occurs. The reference position is predetermined according to each process. For example, the reference position of the surgeon is close to the surgical field, the nurse who puts out the instrument is adjacent to the surgeon, the assistant is the position facing the surgeon through the patient, and the anesthesiologist is the device that measures the patient's biometric data. It is a position adjacent to. The stagnation period extraction unit 202 detects when the medical staff moves from these reference positions as the time when the irregular event occurs.

By the processing flow described above, the time-series data of each operation of the medical staff participating in the surgery and the medical equipment used in the surgery is displayed in a list, so that the delay in the surgery can be clarified. In particular, the screen illustrated in FIG. 7 makes it clear in which step the stagnation period occurred, which facilitates postoperative follow-up analysis. In addition, the importance shown in FIG. 7, the reason in FIG. 8 and the display of improvement measures make it easier to proceed with the postoperative follow-up analysis.

The examples of the present invention have been described above. The present invention is not limited to the above examples, and includes various modifications. For example, the above-described embodiment has been described in detail in order to explain the present invention in an easy-to-understand manner, and is not limited to the one including all the configurations described.
