Description

  The present invention relates to an apparatus for recording a moving image of a surgical operation, and more particularly to a technique for easily searching a necessary moving image portion from among a large number of recorded moving images.

  Surgery (including dental surgery; the same applies hereinafter) requires advanced expertise and skills. It also directly affects the patient's physical life. For this reason, in a surgical operation, moving image recording using a video imaging device has been conventionally performed. Hospitals where surgery is performed store a large number of recorded videos (videotapes), and the number is increasing weekly.

  Recorded videos are necessary for doctors who have little experience with a certain procedure to study the actual flow of surgery and how to deal with emergencies, and to provide sufficient image training, and there were accidents (failures). In case it becomes a valuable asset to investigate the cause. Recently, since accreditation systems for specific techniques are being considered, recording of video at the time of operation is becoming important as a reference material for skill evaluation.

  Traditionally, recording of surgical moving pictures has been performed using a commercially available video camera using videotapes. However, since the amount of recorded video increases only every week, it is very difficult to find the scene you want to see from any stored recording media (videotape) at any hospital. Is real.

  For example, even in the case of ophthalmic surgery where the operation time is relatively short, the time required for the operation is on average 1 to 2 hours. In hospitals where 20 eye surgery operations are performed every week, the number of videotapes increases by 20 and the time increases by about 30 hours. If converted in one year, about 1000 video tapes and about 1500 hours of recorded moving images will increase.

  By the way, a technique for recording such a moving image recording of a surgical operation so that it can be efficiently searched has not been proposed. Incidentally, there is JP-A-2003-39739 as a technique for photographing a moving image recording of a surgical operation. Moreover, as a technique for recording the state of the surgical apparatus and individual patient data at the time of imaging, there are, for example, Japanese Patent Application Laid-Open Nos. 2003-077686 and 2000-276540.

  However, these are proposals for clearly recording the history of the operation over time, and are not techniques for facilitating later retrieval.

  On the other hand, in order to be able to search for a specific scene from moving image data recorded on a video tape, conventionally, two methods are generally used. One is the time code method. This is a method of creating an index image (thumbnail; the same applies hereinafter) at predetermined time intervals. According to this, for example, a glance in a moving image can be extracted every 5 minutes and used as an index image, so that processing is also easy.

  The other is the scene change method. This is a method of creating an index image by capturing a change in a configuration image when a large change occurs in the image configuration of a moving image. Since automatic processing can be performed by capturing changes in color composition and brightness, the processing cost is higher than that of the time code method, but the time code method is comparable to the ease of processing. This method is used, for example, for creating an index based on a scene change of a movie.

The problem lies in that these conventional methods are not suitable for moving image editing in surgery, particularly surgery using a microscope or endoscope. This is because a surgical operation using a microscope or an endoscope does not cause a significant change in the image configuration. Therefore, the present applicant has proposed a device for editing a moving image recorded on a video tape based on the name of the appliance. This is because even in a surgical operation in which similar images are continuous, if a dex is created based on the name of the instrument, a necessary scene can be easily retrieved from a large amount of image data.

  In order to edit a moving image related to a surgical operation, Patent Document 4 may be used. However, this technique needs to record the progress of surgery as a video on a video tape and edit it after a while, so there is still room for improvement in terms of quick editing of the recorded video.

  Therefore, an object of the present invention is to enable storage of a recorded moving image of a surgical operation in a state where it can be quickly searched.

  In order to achieve the above object, a video recording apparatus for surgical operation according to claim 1 includes an index title storage means for storing surgical operation action or instrument name data, and a specific procedure existing in the index title storage unit. Index title selection means for selecting and specifying an action or an instrument, and index creation means for recording a part of a moving image as an index image corresponding to the operation timing of the index title selection means.

  This moving image recording apparatus simultaneously records a moving image and creates an index (thumbnail) during a surgical operation. As a configuration requirement, an index title storage means storing surgical operation action or instrument name data is provided, and the operation action name or instrument name stored in the index title storage means is selected (designated) during the operation. To create an index image.

  The index title selection means for selecting and specifying the treatment action name or the instrument name is operated by a surgeon or a recorder (assistant doctor, nurse, appointment recorder, etc.). You can select and specify while looking at the monitor screen, or simply press the foot pedals in the order that you want. For the selection designation, a command input device such as a so-called mouse, touch pen, keyboard, numeric keyboard, foot pedal or the like can be used. Since the state of the operation is imaged through the moving image recording apparatus, the index title selection / designation unit does not necessarily have to be in a place where the inside of the operating room or the operating room can be seen. This is because the index title can be selected and specified while receiving the video in real time via a dedicated line or public line, so even if it is installed at a remote place away from the operation site, the same effect can be obtained. . The recording device for storing the moving image and the means for creating the index image based on the operation of the index title selection means may be installed not only in the hospital at the operation site but also in a remote place (image management center or the like).

  According to a second aspect of the present invention, the index title storage means can be selected in a regular surgical operation order or an instrument use order in a surgical operation. The selection means for creating the index can be arbitrarily selected and designated with a so-called mouse, touch pen, foot pedal, etc. while looking at the name of the surgical operation and the name of the instrument displayed on the monitor screen. If is displayed randomly, it is difficult to select and decide instantaneously. Therefore, by displaying the surgical operation name and instrument name in a fixed pattern after surgery, the index title selection means can be turned on when the surgical operation name or instrument name changes without looking at the monitor screen. The index can be automatically recorded. When there is an unexpected situation (such as massive bleeding), an index may be created as another item. In such a case, a specific index name may be written later.

  According to the apparatus of the present invention, it is possible to quickly record a specific scene during an operation for which reproduction confirmation is desired as an index image, and it is possible to improve the efficiency of image processing for list display and quick search processing.

  FIG. 1 illustrates a moving image recording apparatus for surgery according to the present invention. This moving image recording apparatus creates index images at the same time when moving image data input from an imaging device 10 that is an external device is stored in a moving image data storage unit 11 such as a hard disk.

  Reference numeral 14 denotes an index title storage unit that stores the names of surgical treatments. It is desirable that the names of treatment actions stored in the index title storage unit 14 are stored in a table format so that they can be displayed in a fixed order that is substantially determined for each technique, and are always displayed on the monitor device 12. . As a matter of course, the index title storage unit 14 stores the order of treatment actions in a plurality of techniques. In addition, depending on the surgeon, it is not uncommon for the surgical operations to be performed in a different order from the standard pattern, so it is desirable to store the sequence of surgical operations in advance for each surgeon.

  Reference numeral 15 denotes a command switch for outputting a timing command for specifying an index image (specification of timing for starting a treatment action). The command switch 15 can employ various input devices, but can be directly operated by a doctor, assistant, assistant, or the like who is performing a treatment, for example, a pressure switch such as a foot pedal, or an audio signal input method performed via a microphone. Can be adopted. This is because the direct input of the foot pedal and the audio signal enables the doctor in charge and the surgeon's assistant to generate the timing command signal without looking at the monitor screen. Of course, even when a doctor or an assistant can afford to glance at the monitor screen, the foot pedal and audio signal input are effective means. The same is true for assistants (nurses, etc.) who are indirectly involved in the treatment. If there is a full-time assistant for creating an index, the person may input the timing of the start of the treatment action through various input devices such as a mouse, keyboard, touch pen, etc. I can do it.

  Taking cataract surgery (lens emulsification) as an example, there are acts in the pre-surgery preparation stage, such as disinfection, eye washing, etc. After the start of surgery, for example, subtenon anesthesia, conjunctival incision, hemostasis, sclera Approximately 20 treatments are performed in the order of tunnel creation. Even after the operation is complete, perform post-operative actions such as wiping your face with wet gauze or applying a protective plate. Searching at a later date is mainly a process from the start to the end of the surgery, but from the pre-surgery to the post-surgery action, in order to prove the correct operation and to investigate the cause of the accident It is desirable to record and record evenly, and it is also desirable to record pre- and post-operative actions with an index. However, since there is no need to search for pre- and post-surgical actions, it is usually displayed separately from the main part (surgical action during surgery), or the search area is set separately from the main part (surgical action during surgery). It is desirable to keep it.

  An unexpected and unexpected situation occurs during the operation. For example, unexpected massive bleeding, heart rate, respiratory rate, or sudden change in body temperature. In such a case, the title cannot be stored in the index title storage unit 14 in advance. For this reason, when a sudden situation occurs, the index title name is divided into “others” categories by, for example, pressing the command switch 15 twice continuously, and the title of the index is assigned after the operation. . A switch for generating a command may be provided separately.

  Reference numeral 16 denotes an index creation unit. In response to the signal from the command switch 15, a part of the moving image is extracted as an index image and stored in the index storage unit 17 with an appropriate layout together with the index title. In the list image stored in the index storage unit 17, preferably, in addition to the name of the treatment action, for example, accompanying data such as an instrument name and an elapsed time from the start of surgery is displayed as a character using characters or figures. Is desirable. Reference numeral 18 denotes an accompanying data input unit, and 19 denotes an accompanying data storage unit. The accompanying data input unit 18 uses, for example, a keyboard numeric keypad (corresponding simple input such as instrument name and doctor name) and a timer device. The accompanying data storage unit 19 can store various items such as a patient name, a disease name, an operation date, a surgeon name, a staff name in charge, a medical record content, and pre- and postoperative feelings. These data can be valuable data when searching for index images and analyzing successful cases and failed cases. Note that the method for displaying a list of index images is not limited.

  Therefore, according to such a configuration, an index image at an arbitrary timing can be created via the command switch 15 when the treatment action changes during the operation. Each time the procedure changes, the doctor or assistant can generate a signal to create an index image, which can solve complicated problems such as editing the index image at a later date, and a large number of videos at any time after surgery. A necessary scene can be searched from the data.

  The list images stored in the index storage unit 17 are means for starting reproduction of moving images, so-called thumbnails for cueing, and do not merely present still images. Therefore, if one of the list images is selected and a moving image is reproduced, it is natural that the moving image is reproduced from the scene.

  In order to narrow down the search, accompanying data is also a clue. The patient name, age, sex, disease name, medical condition, surgeon name, surgical start time, elapsed time since the start, operation record, still image or video at the time of examination, etc. stored in the accompanying data storage unit 20. This is because the search operation becomes easier when there are more narrowing conditions.

  When using a manual switch as a command switch (index title selection means) for specifying the name of a treatment action, etc., the treatment action or instrument name is associated with an identification number or an identification symbol (for example, an acronym). Can be saved. This is because if the name of the treatment action is associated with an identification number or an initial letter, an index title (especially a subtitle) can be easily created using a keyboard or a numeric keypad.

  The command switch of the embodiment described above determines index image creation timing using hands and feet, but the index image creation timing determination means (index title selection means) according to the present invention is a hand. It is not limited to the pressing operation using the foot or the foot. This is because the index image can be generated by detecting a change in the treatment action by means other than the pressing operation. For example, an identification label (for example, a barcode label) may be affixed to each instrument used during surgery, and an index image may be created by reading the identification label via an optical reader device before using the instrument. . Also, a light transmitting / receiving element is placed between the surgeon's standing position and the patient's bed, and when the surgeon's hand or instrument crosses the light of the light emitting element, the surgeon's hand or arm, or the instrument or tool It is also possible to detect entry / exit of the user, determine the start and end of the treatment action based on the entry / exit, and create an index image together with the title when a new treatment action starts.

  The apparatus according to the present invention is mainly used for recording a moving picture of a surgical operation, but the same apparatus may be used to record a moving picture at the time of surgery or medical examination. For example, while recording a moving image at the time of a stomach camera or a large intestine examination, an index is attached to a frame of an affected part to be noted. This is because it is a special data storage format that cannot be obtained from vague conventional video recording because it can quickly call out and play back remarkable frames.

It is a block diagram which illustrates the composition of the editing device concerning an embodiment.
