Description

The present invention relates to surgical information real time acquisition and analysis system and Methods in endoscopic surgery.

  Endoscopic / laparoscopic surgery is performed as follows.

  (A) If it is a chest surgery, the chest wall, and if it is an abdominal surgery, a plurality of small holes are made in the abdominal wall, and each of these small holes is a hollow for inserting and removing a surgical instrument called a trocar cannula. Place the tube.

(B) A surgical operation is performed by inserting a plurality of types of surgical instruments into the hollow tubes for inserting and removing those surgical instruments. Visual recognition of the organ to be operated is performed by an endoscope inserted into one surgical instrument insertion / extraction hollow tube. (The visual recognition by this endoscope may be performed by inserting the endoscope directly from a small incision in some cases.)
(C) While operating a monitor on which a moving image of an organ imaged by an endoscope is projected, a plurality of types of surgical instruments inserted into a surgical instrument insertion / extraction hollow tube are operated to proceed with surgery.

  (D) Necessary operations are performed by exchanging various surgical instruments devised according to surgical operations.

  In general, surgical information acquired at the time of surgical operation is limited to general information such as the operation time and the amount of bleeding, and the order and time of use of each surgical instrument are accurately recorded and stored as information. That is not done.

  However, if there is accurate record information of the usage order and usage time of each surgical instrument, the surgeon can objectively and accurately evaluate the surgery based on such information. It can be used as a reference for surgery. It can also be used as useful information from the viewpoint of improving the skills of doctors and educating newcomers.

  Therefore, in order to record the above detailed surgical information, if a person tries to create a recorded video of an endoscope while observing it, it takes several days to a week even for a surgery of about one hour. It becomes work. In particular, there is a problem that it takes time and effort to measure the usage time of each surgical instrument. Therefore, conventionally, it has been desired to develop a technique capable of acquiring accurate recording information on the use order and use time of each surgical instrument.

  Conventionally, a technique for attaching an RFID tag to a surgical instrument or a chemical container, writing various information such as an owner and sterilized information, and making the management accurate and easy by referring to the information is disclosed in Japanese Patent Application Laid-Open No. 2003-117172 (Patent Document). 1). However, this technique is for management of surgical instruments and the like, and is not for obtaining accurate record information of the order of use and usage time of each surgical instrument.

  Conventionally, Japanese Unexamined Patent Application Publication No. 2005-95567 (Patent Document 2) describes an endoscope system that faithfully reproduces the content of treatment performed during surgery. According to the technique described in Patent Document 2, individual ID information is read wirelessly from an ID tag embedded in an endoscope, an electric scalpel treatment instrument, or the like at an RFID terminal of the system, and the individual ID information is By correlating with the parameter history and the time axis of the image, it is possible to leave as a history what kind of treatment the surgeon has performed. However, the technique of this patent document 2 is surgical information that can be obtained only by observing an endoscopic image all the time, and is merely associated with a treatment tool used for video recording of a surgical field, and insertion of a surgical instrument. -It is not the technique of recording automatically the data of the extraction hollow tube and the surgical instrument inserted / removed with respect to it in real time.

  Further, in Japanese Patent Application Laid-Open No. 2006-254974 (Patent Document 3), an IC tag for identification is attached to each of a plurality of types of endoscopes, and the type of endoscope attached to the eyepiece is indicated by an IC tag reader. Describes a technique for automatically adjusting observation modes such as brightness, hue, and edge enhancement according to the characteristics of each endoscope. However, this Patent Document 3 does not record surgical information, and discloses a technique for automatically recording a surgical instrument insertion / extraction hollow tube and a surgical instrument to be inserted / extracted in real time in association with each other. It has not been.

In general, various data storage means mounted on the computer system 1 are generically named. The memory referred to in this specification is a general term for CPU registers, main memory, temporary memory, and the like, and means the most appropriate memory corresponding to each process. Application software for real-time operation information acquisition / analysis in mirror surgery is installed on the hard disk of the storage device 101. The RFID data input processing unit 103A includes an external bus such as a USB and an expansion bus, and is a generic name for means for inputting RFID tag information to the computer system 1 and a control method. The video data input processing unit 103B includes an image input board and the like, and is a generic name for means and control methods for inputting image data acquired by the endoscope 4 to the computer system 1. The arithmetic processing unit 109 performs all arithmetic processing in the application software for real-time operation information acquisition / analysis in the endoscopic surgery, and includes an arithmetic unit in the CPU. The clock 102 is a part that supervises timing, and includes a clock in the CPU.

  The system for acquiring and holding in real time the data of the surgical instrument name and insertion / removal time inserted into and removed from each hollow tube in the operation information real-time acquisition / analysis system in the endoscopic operation of the present embodiment As elements, an RFID data input processing unit 103A for inputting RFID tag information from the RFID read / write control unit 3, a surgical instrument name, a surgical instrument ID, and an RFID tag ID number for each surgical instrument 6i (usually an IC in the tag) Surgical instrument name / ID correspondence data storage unit 104 for storing surgical instrument name / ID correspondence data indicating a correspondence relationship with the chip), and an arithmetic processing unit 109 for performing various calculations. The operation data processing unit 107 is provided. The RFID data input processing unit 103A sequentially stores the RFID tag information including the hollow tube identification information continuously input to the computer together with the time generated by the clock 102 in the memory. For these pieces of information, the surgical data processing unit 107, together with the arithmetic processing unit 109, identifies the surgical instrument name and determines the insertion / extraction time according to the command of the application software for real-time operation information acquisition / analysis in the endoscopic surgery. The result is stored in the memory together with the hollow tube identification number (the hollow tube identification information may be used as it is or may be newly specified) and the surgical instrument ID. That is, the surgical instrument name is identified by referring to the surgical instrument name / ID correspondence data in the surgical instrument name / ID correspondence data storage unit 104 to read out the surgical instrument name corresponding to the ID. A method for determining the insertion / extraction time of the surgical instrument will be described later.

  In addition, this system operates on the data of the hollow tube identification number stored in the memory of the storage device 101 by the surgical data processing unit 107, the surgical instrument ID, the surgical instrument name, and the insertion / extraction time. As a component for creating the information recording / analyzing file 200, surgical instrument usage data including a surgical instrument name and insertion start time and removal time of the surgical instrument as a set is stored for each hollow tube, and hence the trocar cannula. Each time series is created and recorded in the surgical information recording / analysis file 200 of the storage device 101, and further calculation processing and comprehensive analysis are performed based on the surgical instrument usage data group. Surgery information recording / analysis file creation unit 115 to be recorded in the recording / analysis file 200 and surgery information created by the surgery information recording / analysis file creation unit 115 It displays the contents of the recording and analysis file 200 on the display, and an output processing unit 108 for performing data output, such as to send printed out, or at the network to other systems.

  The computer system 1 in the surgical information real-time acquisition / analysis system in the endoscopic surgery according to the present embodiment further includes a video data input processing unit 103B and a video data processing unit in order to realize a function of automatically linking with a surgical recording video. 111. Video data from the endoscope 4 for photographing the surgical field is input to the computer system 1 via the video data input processing unit 103B, and the video data processing unit 111 records the video data in the mass storage device of the storage device 101. I will do it. The surgical data processing unit 107 identifies the hollow tube and the surgical instrument and determines the surgical instrument insertion / extraction time together with the arithmetic processing unit 109, and at the same time, sets the video position marker number as address information on the video data synchronized with the insertion / extraction time. Create and store in memory.

  The surgical information recording / analysis file creation unit 115 according to the present embodiment creates a surgical instrument name for each surgical instrument name based on the surgical instrument usage information and the video position marker number created by the surgical data processing unit 107 and stored in the memory. The surgical information recording / analysis file 200 is created by adding a video position marker number together with the insertion start time and the removal time of, and recording a set of surgical information in time series for each hollow tube or trocar cannula. Further, for example, when the surgical information recording / analysis file creation unit 115 clicks the video position marker number on the surgical information recording / analysis file 200, only the video data at that time is selected from the video data recorded in the mass storage device. Can be added.

  The surgery information recording / analysis file creation unit 115 may create the surgery information recording / analysis file 200 collectively at the end of surgery, or may be created by the surgery data processing unit 107 and sequentially stored in a memory. The surgical information recording / analysis file 200 may be sequentially created from the surgical data.

  In addition, in order to prevent such surgical information from being lost due to unforeseen circumstances, the surgical information created by the surgical data processing unit 107 and the surgical information recording / analysis file creating unit 115 is sequentially stored in the hard disk in the storage device 101. It may be recorded.

  In addition, when using an electric knife as a surgical instrument, wireless communication between the RFID tag 9i and the RFID antenna 7i may be temporarily disabled due to leakage of the noise. The usage information of the electric knife is created by the algorithm described later.

  Next, the operation of the surgical information real-time acquisition / analysis system in the above-described endoscopic surgery will be described with reference to FIG. Of course, this operation is also a method for obtaining and analyzing surgical information in real time in the endoscopic surgery performed by the computer system 1. A small hole is made in one or a plurality of places (here, three places) of the skin to be operated by the start of the operation, and the trocar cannulas 5A, 5B, and 5C are inserted into the small holes and placed. RFID antennas 7A, 7B, and 7C are attached to the trocar cannulas 5A, 5B, and 5C, and the signal lines 8A, 8B, and 8C of the RFID antennas 7A, 7B, and 7C are connected to the connection terminals of the RFID read / write control unit 3, respectively. 3A, connection terminal 3B, and connection terminal 3C are connected to each other.

  In the following description, the hollow tube identification numbers of the trocar cannulas 5A, 5B, and 5C are “1”, “2”, and “3”. Further, as shown in the table of FIG. 7, the surgical instrument ID number is “101” for the hollow double forceps (1) used, “102” for the hollow double forceps (2), and the three-hole type connection used. The connecting forceps are “111”, the Ogigi forceps (1) is “114”, the Ogigi forceps (2) is “115”, the electric knife is “201”, and so on. Even for the same type of surgical instrument, the surgical instrument ID and surgical instrument name are attached to each individual. The correspondence between these surgical instrument names, the corresponding surgical instrument ID numbers, and the ID number of the RFID tag (a number of digits given in advance to the IC chip in the tag) is the surgical instrument name / ID correspondence data in advance. The surgical instrument name / ID correspondence data storage unit 104 is registered.

  Prior to the start of the endoscopic surgery, the imaging time of the video data of the endoscope 4 is set to be exactly the same as the surgical instrument usage time.

  The surgery is started, and the surgeon receives the necessary surgical instrument (here, the hollow double forceps (1) with the surgical instrument ID number “101” to which the RFID tag 91 is attached) and receives one of the trocar cannulas 5A, 5B, 5C. (In this case, it is assumed that the trocar cannula 5A is first inserted into the hollow tube identification number “1”), the RFID tag 91 and the RFID antenna 7A attached to the hollow double forceps (1) are inserted. The communication is started, and the RFID antenna 7A receives the ID number in the IC chip of the RFID tag 91 and inputs it to the RFID read / write control unit 3 through the signal line 8A and the connection terminal 3A.

  While the communication between the RFID antenna 7A and the RFID tag 91 is continued, the RFID read / write control unit 3 detects the ID number of the RFID tag 91 and the number “1” of the trocar cannula 5A (that is, the hollow tube identification number). Are continuously transmitted to the computer system 1. Alternatively, control may be performed such that only the RFID tag information at the start of communication is transmitted to the computer system 1.

  In the computer system 1, the hollow tube identification number “1” of the trocar cannula 5 </ b> A and the ID number of the RFID tag 91 are input to the RFID data input processing unit 103 </ b> A from the RFID read / write control unit 3. Stored in At the same time, the operation data processing unit 107 acquires the time synchronized with the input signal from the clock 102 and stores it in the memory. At the same time, the surgical data processing unit 107 refers to the surgical instrument name / ID correspondence data storage unit 104 together with the arithmetic processing unit 109, and the surgical instrument ID number “101” to which the RFID tag 91 is attached is operated. The hollow double forceps (1) which is the instrument name is acquired and stored in the memory. At the same time, the time when the RFID tag information is first input (that is, the time when the RFID tag and the RFID antenna start communication) is determined as the insertion start time of the hollow double forceps (1) and held in the memory. To do. Alternatively, when only the RFID tag information at the start of communication is input to the computer system 1, the time when the signal or information is input is acquired from the clock 102 and is determined as the insertion start time of the hollow double-opening forceps (1). As described above, the surgical data processing unit 107 includes the identification number “1” of the trocar cannula 5A, the surgical instrument ID “101”, the surgical instrument name “hollow double forceps (1)” corresponding to the ID, and the insertion thereof. A set of time information is stored in the memory.

  In addition, the video data captured by the endoscope 4 is sequentially displayed on the monitor 2 and simultaneously input to the computer system 1 via the video data input processing unit 103B, and the video data processing unit 111 acquires the time acquired from the clock 102. Video data is recorded together with the data in a mass storage device such as a hard disk of the storage device 101. As described above, the operation data processing unit 107 determines the insertion start time of the hollow double forceps (1) into the trocar cannula 5A, and simultaneously creates an image position marker number (TC1-1 in FIG. 11) and stores it in the memory. To do. At the same time, the video data processing unit 111 records this video position marker number in synchronization with the video data recorded in the storage device 101.

  Thereafter, when the hollow double-opening forceps (1) is removed from the trocar cannula 5A, communication between the RFID antenna 7A of the trocar cannula 5A and the RFID tag 91 of the hollow double-opening forceps (1) is interrupted. 101 "cannot be acquired, and the RFID tag ID number from the RFID read / write control unit 3 is not input to the computer system 1 at this time (this is not necessarily the computer system 1 from the RFID read / write control unit 3). Does not mean that the input signal is lost). In the computer system 1, the hollow double forceps (1) is removed from the trocar cannula 5 A (number “1”) in the computer system 1 by the same processing as when the surgical instrument is inserted by the surgical data processing unit 107 or the like. The surgical instrument ID “101”, the surgical instrument name “hollow double forceps (1)”, and the identification number “1” of the trocar cannula 5A are stored in the memory. Also, the video data is processed in the same manner as at the time of insertion, and a video position marker number (TC1-2 in FIG. 11) is given to the video data that coincides with the removal time, and is paired with the surgical instrument usage information at the time of removal. This video position marker number is also stored in the memory.

  Similarly, the hollow double forceps (2) having the surgical instrument ID “102” is inserted into the trocar cannula 5B (hollow tube identification number “2”), and the RFID tag 92 and the RFID antenna 7B attached to the instrument are attached. When the communication is started, the RFID tag ID number of the built-in IC chip of the RFID tag 92 and the hollow tube identification number “2” are input to the computer system 1 via the RFID read / write control unit 3. Upon receiving this input, the computer system 1 determines the input start time, that is, the communication start time, as the insertion start time in the same manner as described above, and at that time, the trocar cannula 5B (hollow tube identification number “2”) is assigned. A set of data that the surgical instrument name “hollow double forceps (2)” of the surgical instrument ID “102” is inserted is held in the memory. At the same time, video data that has been input from the endoscope 4 to the computer system 1 via the video data input processing unit 103B and the video data processing unit 111 and recorded in the storage device 101 is synchronized with the insertion start time. A position marker number (TC2-1 in FIG. 11) is created and recorded. The video position marker number is stored in the memory in a pair with the surgical instrument usage information.

  If the surgical instrument name “Hollow Double Forceps (2)” with the surgical instrument ID “102” is removed from the trocar cannula 5B, the three-hole ligature forceps with the surgical instrument ID “111” is inserted into the trocar cannula 5A. If it is inserted, the computer system 1 converts the RFID tag ID number from the RFID tag 93 attached to the instrument into the surgical instrument ID “111” as described above, and the identification number “1” of the trocar cannula 5A. ”, The surgical instrument name“ three-hole ligating forceps ”, the insertion start time, and the video position marker number (TC1-3 in FIG. 11) which is the video marker at the insertion start time.

  In this way, the surgical data processing unit 107 obtains the acquired hollow tube identification number, surgical instrument ID, surgical instrument name, insertion start time data, video position marker number which is a video marker at the insertion start time, and then the hollow tube identification. The number, surgical instrument ID, surgical instrument name, removal time data, and video position marker number, which is a video marker at the time of removal, are stored in the memory in the order of input.

  Next, a surgical information recording / analysis file 200 is created using the hollow tube identification number, surgical instrument ID, surgical instrument name, insertion / removal time data, and video position marker number stored in the memory by the surgical data processing unit 107. The operation | movement which performs is demonstrated (FIG. 11).

  As described above, the surgical data processing unit 107 associates the hollow tube identification number, the surgical instrument ID, the surgical instrument name, the insertion / extraction time, and the video position marker number, and stores them in the memory in the order of input. The information recording / analysis file creation unit 115 registers surgical instrument use / endoscopic marker data with a set of surgical instrument name, insertion time or extraction time, and video position marker number in time series for each hollow tube. A surgical information recording / analysis file 200 is created.

  Further, according to the above specific example, the hollow double forceps (1) is used in the trocar cannula 5A, but the use time of the hollow double forceps (1) can be measured from the difference between the removal time and the insertion time. It is also possible to display it. Further, in the trocar cannula 5A, the insertion and removal of the hollow double forceps (1) was followed by the insertion of the three-hole ligature forceps. The hollow double-forceps (1) was removed from the insertion time of the three-hole ligature forceps. By subtracting the time, the time required for exchanging the instrument from the hollow double-opening forceps (1) to the three-hole ligature forceps (instrument exchange time) can also be calculated.

  The creation of electrosurgical instrument usage data is special. When using an electric scalpel, high frequency noise is generated, which can disrupt communication between the RFID tag attached to the electric scalpel and the RFID antenna of the trocar cannula into which the electric scalpel is inserted. This causes misrecognition as described in detail below regarding insertion and removal of the electric knife. A method for dealing with this misrecognition in software is shown in FIGS. As shown in the timing chart of FIG. 8, when an electric knife (surgical instrument ID “201”) is inserted into the trocar cannula 5A (hollow tube identification number “1”) at timing T1, an electric knife is inserted at the time of insertion. And the RFID antenna 7A of the trocar cannula 5A (hollow tube identification number “1”) into which the RFID tag is inserted, and the RFID antenna 7A is in contact with the surgical instrument ID “ 201 "(assuming that the ID number of the RFID tag is set to 201). This surgical instrument ID is input to the computer system 1 together with the hollow tube identification number “1” via the RFID read / write control unit 3, and the electric scalpel is inserted into the trocar cannula 5 A (hollow tube identification) by the computer system 1. It is determined that the number “1”) is inserted at time T1. However, at timing T2 immediately after that, the use of the electric knife is started (the switch of the electric knife is turned on), and a large noise leakage occurs as described above. Due to the generated noise, wireless communication cannot be performed between the RFID tag attached to the electric knife and the RFID antenna 7A attached to the trocar cannula 5A in which the electric knife is inserted. When the use of the electric knife stops at timing T3 (the electric knife switch is turned off), wireless communication is resumed between the RFID tag and the RFID antenna 7A in which the RFID tag is inserted again. The electrosurgical instrument ID “201” is acquired again. However, since the electric knife is removed immediately after use, the RFID tag of the electric knife and the RFID antenna 7A of the trocar cannula 5A into which the electric knife is inserted at the timing T4 when the electric knife is removed from the trocar cannula 5A. Communication between is terminated. When the surgical instrument usage data and the surgical information recording / analysis file 200 are created by the above procedure, the insertion / extraction period T1 to T4 of the electric knife is actually a short time T1 to T1 which is impossible in reality. During T2, it is erroneously recognized as insertion / extraction only between T3 and T4. Further, the period during which the electric knife is actually turned on and the electric knife is used is erroneously recognized as a period when no surgical instrument is used in the trocar cannula 5A.

  Further, as shown in FIG. 9, the case where the electric knife is turned on / off three times during the insertion / extraction of the electric knife with respect to a certain trocar cannula 5A only once will be considered. In this case, if the electric knife is inserted into the trocar cannula 5A at timing T11, the RFID antenna 7A receives the surgical knife ID “201” of the electric knife, and this surgical instrument ID is the RFID read / write control unit. 3 is input to the computer system 1 together with the hollow tube identification number “1”. Then, the computer system 1 determines that the electric knife has been inserted into the trocar cannula 5A (hollow tube identification number “1”) at time T11. However, at timing T12 immediately after that, the switch of the electric knife is pushed and large noise leakage occurs as described above. The generated noise prevents wireless communication between the RFID tag and the RFID antenna 7A in which it is inserted. Then, once the electric knife is switched off at timing T13, communication is resumed between the RFID tag and the RFID antenna 7A in which it is inserted again, and the surgical instrument ID “201” of the electric knife is again used. Is acquired. Thereafter, if the switch of the electric knife is pressed again during the timing T14 to T15, the reception of the surgical instrument ID “201” is stopped again during the period of T14 to T15. After that, when the switch of the electric knife is pushed again at the timing T16 and the switch is turned off at the timing T17, the reception of the surgical knife ID “201” of the electric knife is stopped again during the timing T16 to T17. . Then, the use of the electric knife is finished, and the electric knife is removed from the trocar cannula 5A at timing T18.

  In the case of such a usage mode, it is assumed that there are four times of use in a short time that is not actually possible between timings T11 and T12, between timings T13 and T14, between timings T15 and T16, and between timings T17 and T18. Surgical instrument usage data and surgical information recording / analysis file 200 are created. However, this is due to misrecognition, and the true number of uses of the electric knife must be one. Therefore, when the surgical data processing unit 107 creates the surgical knife usage data of the electrosurgical unit, the same hollow tube identification number is continuously generated N times with no electrosurgical instrument. When the insertion / extraction record of the surgical instrument ID “201” is recorded, the surgical instrument usage data of the electric knife is used once. That is, the surgical knife use data that the electric knife is used only once for the period of the timings T11 to T18 is created and stored in the memory. If necessary, the surgery information recording / analysis file creation unit 115 creates a surgery information recording / analysis file 200 from this data, and appropriately records / saves it in the hard disk of the storage device 101.

  Also, the use of an electric knife between the RFID tag attached to another surgical instrument inserted into another trocar cannula and the RFID antenna attached to the trocar cannula into which it is inserted. It can also happen when communication is interrupted. As a countermeasure for this, the surgical data processing unit 107 has a period in which the insertion and removal of the surgical instrument having the same surgical instrument ID as the other same hollow tube identification number is repeated in synchronization with the electrosurgical instrument usage data. For the surgical instrument use data of the surgical instrument for one time, with the first reading start time in a series of insertion / extraction repetition periods including the period as the insertion start time and the last extraction detection time in the insertion / extraction repetition period as the extraction time. Create and store in memory. The surgical information recording / analysis file creation unit 115 may create the surgical information recording / analysis file 200 and sequentially register the surgical instrument usage data.

  FIG. 10A and FIG. 10B show an example of the above-described surgical information acquisition / analysis algorithm in the form of a flowchart and three trocar cannulas as an example.

  Step S1: The surgical information acquisition / analysis algorithm creates and opens a surgical information recording / analysis file 200 that is a file for recording / displaying surgical information acquired and analyzed in the target surgery. At the same time, the operation information recording / analysis file creation unit 115 enters a state of storing information in the time-series operation information recording / analysis file 200 of the storage device 101. Alternatively, the operation information recording / analysis file 200 may be created after all the operation information is acquired.

  Step S2: When a surgical instrument is inserted into any of the trocar cannulas 5A to 5C, the trocar cannula identification number (port number in FIGS. 10A and 10B) is displayed together with the RFID tag information of the surgical instrument. Is input. In the computer system 1 (the detailed processing steps in the computer system 1 are the same as described above and are omitted here), the port number is first determined.

  Steps S3-A to S3-C: Proceed to each processing A according to the determined port number.

  Steps S31 to S45: Shown in process A (FIG. 10B). First, a surgical instrument ID is acquired (S31), and it is determined whether or not the inserted surgical instrument is an electric knife (whether or not the newly acquired surgical instrument ID is an electric knife) (S32). If the surgical instrument ID is that of an electric knife, whether or not the previous surgical instrument ID obtained with the trocar cannula was that of an electric knife (whether or not the surgical instrument used before was an electric knife) (S38). If the previous surgical instrument ID is not the electrosurgical instrument ID, the time when the electrosurgical instrument ID is started to be acquired is determined as the insertion time. Also, a video position marker number is created, and the video position marker number is recorded on the endoscope video data synchronized with the insertion time. Then, the surgical instrument name, insertion time, and video position marker number corresponding to the surgical instrument ID are stored in the memory (S39, S40). Then, the record of the previously acquired surgical instrument ID (the previous instrument ID) is updated with the currently acquired surgical instrument ID (current instrument ID), and the process returns (S41).

  If the previously acquired surgical instrument ID corresponds to the electric knife in step S38, the previous instrument ID is not updated with the current instrument ID (the result is the same even if updated) (in S38). Branch to True). As a result, even if the electric knife is switched on / off during the period in which the electric knife is inserted into a trocar cannula, it is not recognized that the electric knife has been inserted or removed.

  In step S32, when the ID of the current instrument does not correspond to the electric knife, it is determined that a normal surgical instrument is newly inserted into the trocar cannula, and for the acquired surgical instrument ID, As described above, the insertion time is acquired, a video position marker number is created, and the surgical instrument name, insertion time, and video position marker number corresponding to the surgical instrument ID are stored in the memory. Further, the video position marker number is recorded on the endoscope video data synchronized with the insertion time (S33, S34).

  If the surgical instrument ID acquired last time is that of an electric knife, it is determined that the use of the electric knife has been completed and another surgical instrument has been newly inserted into the same trocar cannula, and the trocar cannula The information on the removal of the electric knife is recorded using the latest removal time of the electric knife in step S35, and the process returns (S35, S36). On the other hand, if it is determined in step S35 that the surgical instrument ID acquired last time is not that of an electric knife, the ID of the last used instrument is updated with the surgical instrument ID acquired this time, and the process returns (S37).

Furthermore, if the surgical instrument ID cannot be obtained in the first trocar cannula in the first step S31, it is determined that the surgical instrument has been removed, and the removal time is obtained (S42). If the ID of the appliance used last time corresponds to the electric knife, the removal time is held as a temporary removal time for the electric knife and the process returns (S43, S44). On the other hand, if the ID of the last used instrument does not correspond to the electric knife in step S43, it is recorded as the removal time of the surgical instrument ID for the surgical instrument (stored in the memory or recorded in the surgical information recording / analysis file 200). And return (S43, S45)
S4-A, S4-B, S4-C: Returning to the flowchart of FIG. 10A, when the process A is completed for any of the port numbers 1 to 3, that is, the trocar cannulas 5A to 5C, the use of the current port is finished. If the use of the current port is not completed, the processing from step S2 is repeated.

  S5-A, S5-B, S5-C: If it is determined that the use of the current port is finished, it is determined whether or not the last surgical instrument is an electric knife.

  S6-A, S6-B, S6-C: If it is an electric knife, the removal information regarding the electric knife is recorded using the removal time for the electric knife, and the process proceeds to Step S7. On the other hand, if the last surgical instrument is not an electric knife, the process proceeds to step S7 as it is.

  S7: It is determined whether insertion / extraction measurement has been completed for all ports and trocar cannulas.

  S8, S9: When the measurement is completed for all trocar cannulas, the measurement result is output to the surgical information recording / analysis file 200 shown in FIG. Furthermore, the surgical record analysis as shown in FIGS. 12 to 15 is added if necessary, and the surgical information recording / analysis file 200 is closed.

  In this way, according to the surgical information real-time acquisition / analysis system in the endoscopic surgery of the present embodiment, the plurality of trocar cannulas 5A, 5B, 5C and a plurality of types of surgical instruments 6i that are inserted into and extracted from each. The surgical information recording / analysis file as shown in FIG. 11 is associated with the name of the surgical instrument and the video position marker number corresponding to the surgical instrument insertion / removal time added to the video data photographed by the endoscope 4 at the same time. 200 can be automatically created in real time. The surgeon can record and analyze the surgery information recording / analysis file 200 by using this information, so that the surgeon can objectively and accurately evaluate the surgery. it can. It can also be used as useful information from the viewpoint of improving the skills of doctors and educating newcomers.

  As described above, the surgical information recording / analysis file 200 of FIG. 11 processes the hollow tube identification number, the surgical instrument ID, the surgical instrument name, and the insertion / extraction time data, and each of the trocar cannulas 5A, 5B, 5C. The hollow tube identification numbers are “1”, “2”, and “3”, respectively, and used surgical instrument information and endoscopic video information corresponding to the information are time-series for each trocar cannula.

  12 to 15 show a summary of surgical instrument usage information. These examples are only examples of data processing for the hollow tube identification number, the surgical instrument ID, the surgical instrument name, and the insertion / extraction time data stored in the memory by the surgical data processing unit 107, and according to the user's request. A summary of various aspects can be presented. FIG. 12 shows the analysis of the hollow tube identification number, the surgical instrument ID, the surgical instrument name, and the insertion / extraction time data stored in the memory of the storage device 101. The number of times of use (number of insertions / removals), the frequency of use, and the total time of use for each surgical instrument are summarized for each surgical instrument used in FIG. In this case, different types of surgical instruments of the same type are combined into one. As a graph created based on this data, FIG. 13 shows a bar graph of the types of surgical instruments used and their number of uses, FIG. 14 shows a pie chart of the frequency of use for each surgical instrument, and FIG. The pie chart of the ratio for which the use time for every surgical instrument occupies with respect to use time is shown. These data processing can be similarly performed on the surgery information recording / analysis file 200 created by the surgery information recording / analysis file creation unit 115.

  From such an analysis, for example, in this surgery, it can be observed that the number of insertions and withdrawals of the suction tube (thin) is large, the frequency of use thereof is high, and the total use time of the hollow double forceps is long. And compared with the conventional similar operation, the tendency of this operation can be grasped. In addition, if this operation is performed by a relatively inexperienced surgeon, it is possible to analyze the tendency of an inexperienced surgeon by comparing it with the data obtained at the same time by a veteran doctor who has already been acquired. It can also be used to investigate the elements necessary to do this.

  In the above embodiment, by linking the video data obtained by the endoscope with the surgical instrument usage data, for example, the hollow double forceps are inserted into the trocar cannula 1 in the surgical information recording / analysis file 200 of FIG. By clicking the use start time with a pointing device, the video of the endoscope can be reproduced from the video position marker number TC1-1 (here, the time mark 16:55:22), and this hollow double forceps is used. It will be possible to reproduce the state of the surgical field during the period. Similarly, if the use start time 17:00:13 when the electric knife is inserted into the trocar cannula 1 is clicked with a pointing device, the video position marker number TC1-5 (here, the time mark 17:00:13) The image of the surgical field photographed by the endoscope can be reproduced, and the image of the surgical field photographed by the endoscope during the period using the electric knife can be reproduced.

  However, the present invention is not limited to this, and if a link with video is not required, the system can be simplified by omitting the function of this portion. In that case, in the configuration of FIG. 6, the video data input processing unit 103B and the video data processing unit 111 can be omitted.

(Second Embodiment)
FIG. 16 shows a surgical information real-time acquisition / analysis system in the endoscopic surgery according to the second embodiment of the present invention. This embodiment is characterized by an RFID tag 9′i attached to a surgical instrument. In the first embodiment, an RFID tag having a perforated disk shape is used. Instead, in this embodiment, an adhesive is applied to the back surface, and in the case of a metal surgical instrument, a metal is used. The difference is that a film-like RFID tag 9′i whose surface is subjected to treatment for preventing electromagnetic induction on the surface is used, and the structures of the RFID antennas 7′A, 7′B, and 7′C are also different. The other configuration is the same as that of the first embodiment, and in FIG. 16, elements common to those in FIG.

  FIG. 17 shows the structure of the RFID antenna 7'i. In the case of the first embodiment, the coil antenna 73 is adopted like the RFID antenna 7i shown in FIG. 4, but in the case of this embodiment, the RFID antenna 7'i has a film-like RFID tag 9'i. The loop antenna 73 ′ is employed so that communication with good sensitivity is possible.

  The fundamental difference between the disc-shaped RFID tag 9i of the first embodiment and the film-like RFID tag 9'i of the present embodiment is the direction of the small antenna with a built-in tag, which differs by 90 °. The antenna surface with the disk-shaped tag built-in is attached so as to be orthogonal to the shaft axis of the surgical instrument 6i, but the film-like RFID tag 9'i is attached to the shaft of the surgical instrument 6i. Parallel. Therefore, the antenna surface of the RFID antenna 7'i attached to the trocar cannula 5A or the like also needs to be 90 ° different between the disc-shaped tag 9i and the film-shaped RFID tag 9'i.

  The built-in antenna 73 ′ of the RFID antenna 7′i capable of effectively communicating with the film-like RFID tag 9′i of the present embodiment is made of a loop antenna, and as shown in FIG. 17, the trocar cannula 5A And so on. In FIG. 17, the other structure of the RFID antenna 7'i and the structures of the connectors 511 and 521 are the same as those in the first embodiment. As a result, most of the communication radio waves (or the direction of the magnetic force lines when communicating by electromagnetic induction) are launched across the entrance of the trocar cannula 5A, etc., and are effective between the antenna built in the film-like RFID tag 9'i. Can communicate.

  The built-in antenna 73 ″ of the RFID antenna 7 ″ i can be of a type surrounding almost the entire circumference of the inlet of the trocar cannula 5A or the like as shown in FIG. Alternatively, the entrance of the trocar cannula 5A and the like can be surrounded by 1/3 round and 2/3 round, depending on the diameter and number of turns of the loop antenna, the capacitor value, and the electrical resistance value. Various surrounding ranges are possible.

  Also in the present embodiment, the video data input processing unit 103B and the video data processing unit 111 can be omitted in the configuration in the computer system 1 (FIG. 6).

  In the case of the present embodiment, since the RFID tag 9'i is easier to handle than the first embodiment, in addition to the same operations and effects as the first embodiment, the manufacture of the system is easy. There are advantages.

  In both of the above embodiments, the RFID read / write control unit 3 uses a three-terminal input, but this communicates with the RFID antennas 7A, 7B, 7C of the trocar cannulas 5A, 5B, 5C. A separate RFID read / ride control unit can also be employed.

  In addition, with regard to the RFID antenna, instead of a structure that can be retrofitted to a hollow tube for insertion / extraction of a surgical instrument such as an existing trocar cannula, insertion of a surgical instrument in which the RFID antenna is attached from the beginning as a product -A hollow tube for extraction can also be adopted.

(Third embodiment)
A surgical information real-time acquisition / analysis system in the endoscopic surgery according to the third embodiment of the present invention will be described with reference to FIGS. Reference numerals common to the first embodiment indicate common elements.

  The feature of this embodiment is a method in which the acquisition of the surgical instrument insertion / extraction time is left to the optical sensor, and the acquisition of the surgical instrument ID is left to the RFID. In the present embodiment, RFID antenna devices 70A, 70B, and 70C that are retrofitted to an existing surgical instrument insertion / extraction hollow tube (or an RFID antenna that is integrally attached to the surgical instrument insertion / extraction hollow tube as a product) The devices 70A, 70B, and 70C) insert and remove the surgical instrument 6i together with the RFID antennas 7A, 7B, and 7C similar to those in the first embodiment that receive the ID of the RFID tag 9i attached to the surgical instrument 6i. Optical sensors 21A, 21B, and 21C for detection are incorporated, and if each of the RFID antennas 7A, 7B, and 7C detects the ID of the RFID tag 9i, an output is output to the RFID read / write control unit 3 through the cables 8A, 8B, and 8C, respectively. At almost the same time, the optical sensors 21A, 21B, 21C are connected to the RFID antenna device 70A, 0B, 70C that any of the surgical instrument 6i respectively is inserted, also detects that it is inserted, so that output cables 8A, 8B, 8C through each optical sensor control unit 22.

  The RFID tag of FIG. 19 illustrates the holed disk-shaped tag according to the first embodiment, but a film-like RFID tag 9′i may be adopted as the RFID tag as in the second embodiment. it can. In this case, the RFID antenna includes an RFID antenna 7′i having a loop antenna 73 ′ shown in FIG. 17 and an RFID antenna 7 ″ i having a loop antenna 73 ″ shown in FIG. An RFID antenna suitable for communication with a small antenna with a built-in film-like RFID tag is adopted. Of course, the surrounding range of the hollow tube inlet of the loop antenna is not limited to the examples of FIGS.

  In this embodiment, the optical sensor control unit 22 is provided with connection terminals 22A, 22B, and 22C for three signal lines 8A, 8B, and 8C, and 8A-22A, 8B-22B, and 8C-22C. Each signal line 8A, 8B, 8C is connected to each connection terminal 22A, 22B, 22C so as to be a combination. This combination is optional as long as it is not changed during the operation.

  Hereinafter, when it is not necessary to identify A, B, and C, the optical sensor 21, the RFID antenna 7, the cable 8, the RFID antenna device 70, and the trocar cannula 5 will be described.

  As shown in detail in FIG. 23, the optical sensor 21 includes a light emitting unit 211 incorporated together with the RFID antenna 7 in the RFID antenna device 70, and a light receiving unit 212 disposed opposite to the light emitting unit 211 through a hollow portion. The cable 8 is connected so as to supply power to the light emitting unit 211 and to output a light reception signal of the light receiving unit 212. Now, as shown in FIG. 23A, in the state where the surgical instrument is not inserted into the RFID antenna device 70, the light 213 from the light emitting unit 211 is received by the light receiving unit 212, and the light receiving unit 212 receives the light reception signal. Output to cable 8. On the other hand, as shown in FIGS. 22 and 23 (b), when any surgical instrument 6i is inserted into the trocar cannula 5 for surgery, it is first placed in the RFID antenna device 70 located at the rear end opening. At this time, the surgical instrument 6i into which the light 213 from the light emitting unit 211 is inserted is blocked, and the light 213 does not reach the light receiving unit 212. In this case, the light receiving unit 212 stops or attenuates the output of the received light signal that has been output so far. The change in the light reception signal of the light receiving unit 212 is input to the computer system 1 via the optical sensor control unit 22. Judgment of the insertion / extraction of the instrument in the computer system 1 uses the change of the light reception signal (light reception amount).

  As illustrated in FIGS. 19 to 23, the optical sensor 21 is shown to be located on the back side of the RFID antenna 7, but particularly in the case of the RFID antenna 7 ′ i or 7 ″ i of the second embodiment, The front side of the optical sensor 21 may be used.

  The wavelength of the light of the optical sensor 21 may be basically any wavelength, and is not limited to the visible light region. Further, laser light may be used.

  Further, a reflective optical sensor may be used as the optical sensor 21. In this case, the light emitting unit 211 and the light receiving unit 212 of FIG. 23 are arranged on the same side, and a reflecting plate is arranged to face them. The reflecting plate may be made of either a material with good reflectivity or a material with low reflectivity. In either case, the reflected light amount when the instrument is not inserted is used as a baseline, and the algorithm captures the change in the reflected light amount due to the instrument insertion.

  The RFID antenna 7 in the RFID antenna device 70 is the same as that in the first embodiment.

  If the processing function of the computer system 1 of this embodiment is disassembled into blocks, the configuration shown in FIG. 24 is obtained. FIG. 24 is the same as FIG. 6 except for the optical sensor signal input processing unit 103C. The feature of the present embodiment is that the acquisition of the surgical instrument insertion / extraction time is left to the optical sensor, and the surgical instrument ID acquisition is left to the RFID, so that surgical information real-time acquisition / analysis in the endoscopic surgery of the present embodiment In the first application software, an algorithm that considers electromagnetic interference due to the electric knife is not required as in the first and second embodiments.

  The light reception signal of the light receiving unit 212 of the optical sensor 21 is input to the computer system 1 via the optical sensor control unit 22 and the optical sensor signal input processing unit 103C. Here, when a certain surgical instrument is inserted into the hollow tube (trocar cannula), the light reception signal of the light receiving unit 212 changes. When this change exceeds the set standard, the instrument insertion and operation data processing unit 107 determines together with the arithmetic processing unit 109, acquires the time from the clock 102, and stores it in the memory as the instrument insertion time. Since the RFID tag is not usually attached to the distal end portion of the surgical instrument, the optical sensor determines insertion of the instrument before the communication between the RFID antenna and the RFID tag starts. Therefore, the optical sensor control unit 22 also needs to transmit hollow tube identification information for identifying each of the trocar cannulas 5A, 5B, and 5C to the computer system 1 (or the optical sensor control unit 22 is connected to the computer system 1). An input port number such as a connected USB port is used as the hollow tube identification information). The hollow tube identification information is also transmitted from the RFID read / ride control unit as in the first and second embodiments. If electromagnetic interference occurs with an electric knife, it is determined that the instrument has been removed because the input of RFID tag information is interrupted in the same hollow tube, but no change is observed in the optical sensor signal. It is determined that it remains in the hollow tube. As described above, when there is a contradiction between the RFID system and the optical sensor system in the appliance removal determination, an algorithm that prioritizes the determination of the optical sensor system is used. The ID acquisition of surgical instruments is left to the RFID system.

  Even in the present embodiment, it is necessary to process the video from the endoscope 4 for photographing the surgical field in order to realize a function of automatically linking with the endoscopic video. Since it is the same as the first and second embodiments except that the insertion time and removal time of the surgical instrument are determined by the optical sensor 21, description thereof will be omitted.

  Also in the present embodiment, the video data input processing unit 103B and the video data processing unit 111 can be omitted in the configuration in the computer system 1 (FIG. 24).

  Even in this embodiment, if the RFID antenna is retrofitted to a surgical instrument insertion / extraction hollow tube such as an existing trocar cannula, it is the same as in the first embodiment. The mounting structure shown in FIGS. 4 to 5 can be employed. In addition, other modifications similar to those of the first embodiment are possible.
