- video information about the surgical site (surgical site video information) is transmitted from the imaging device to the video processor, and the surgical site video is displayed on a display device such as a monitor in the operating room by the video processor.
- communication between the imaging device and the video processor is often wired communication.
- an imaging device that exists in a clean area and a video processor that exists in an unclean area are connected by a cable or the like, so care must be taken to maintain the clean area. .
- the burden of the sterilization process of the cable is not small.
- the movement of medical staff in the operating room may be hindered by the cable being installed on the floor.

- these people and objects may move during the operation, and their positions are not constant. For example, if these persons or objects enter the communication path between the imaging device and the video processor, transmission / reception of radio waves between the two is hindered, and there is a possibility that images cannot be displayed stably.
- Patent Document 1 corresponds to a technique for selecting a communication path capable of performing communication more stably from a plurality of communication paths.

Therefore, the technique cannot be applied to communication in the operating room as it is. Further, as described above, in consideration of the medical use, it is necessary to avoid a situation in which the communication between the imaging device and the video processor becomes unstable during the operation and the video is disturbed. From this point of view, a technique for switching communication paths after detecting that communication has become unstable like the technique described in Patent Document 1 is not a technique suitable for medical use.

- compressing the surgical part video may lead to degradation of image quality and display delay. Since the surgeon performs various treatments while viewing the surgical operation image displayed on the display device, such a deterioration in image quality and delay in display may hinder smooth surgery. Therefore, a method of transmitting an operation part image after compressing it, which may cause deterioration in image quality or display delay, is not preferable in medical applications.

It is necessary to provide the device. Accordingly, there is a possibility that the size of the imaging device is increased and the operability of the medical staff who operates the imaging device is lowered.

本開示の一実施形態について説明するに先立ち、本発明者らが既存の一般的な技術について検討した結果について説明するとともに、本発明者らが本開示に想到した背景について説明する。
本開示の第1の実施形態について説明する。なお、以下では、第1の実施形態及び後述する第2の実施形態の一例として、患者の術部を撮影する撮像装置が内視鏡である場合について説明する。ただし、本実施形態はかかる例に限定されず、撮像装置は、例えば顕微鏡(手術用顕微鏡)等、術部を撮影するための他の機器であってよい。
図1を参照して、本開示の第1の実施形態に係る通信制御システムの構成について説明する。図1は、本開示の第1の実施形態に係る通信制御システムの概略構成を示す図である。
図3を参照して、第1の実施形態に係る通信制御システム1の機能構成について説明する。図3は、第1の実施形態に係る通信制御システム1の機能構成の一例を示す機能ブロック図である。図3は、図1及び図2に示す通信制御システム1の各機器が有する機能を、機能ブロックとして図示したものに対応する。機能ブロックとして図示する各機能は、内視鏡10、中継器20、ビデオプロセッサ30及び術場カメラ40のそれぞれに設けられる、CPUやDSP、GPU等の処理回路が、所定のプログラムに従って動作することにより実現される。なお、図3では、情報の送受信を表す矢印のうち、無線通信によって情報が送受信されるものを一点鎖線の矢印で示し、有線通信によって情報が送受信されるものを実線の矢印で示している。
図4を参照して説明したように、図3に示す通信状況把握部301は、通信経路に対して障害物が侵入しているかどうかに応じて、当該通信経路の通信状況を把握する。ここでは、図5を参照して、通信経路に対して障害物が侵入しているかどうかを判断する基準等、第1の実施形態において通信状況把握部301によって実行される通信状況把握処理についてより詳細に説明する。図5は、第1の実施形態において通信状況把握部301によって実行される通信状況把握処理についてより詳細に説明するための説明図である。
図6を参照して、第1の実施形態に係る通信制御方法の処理手順について説明する。図6は、第1の実施形態に係る通信制御方法の処理手順の一例を示すフロー図である。
本開示の第2の実施形態について説明する。
第2の実施形態では、図3に示す通信状況把握部301によって、術場映像に基づいて、手術室内の物体(図4に示す例であれば、内視鏡10のアンテナ、複数の中継器20a~20cのアンテナ及び障害物(医療スタッフ501))の位置が検出される。この際、通信状況把握部301は、障害物の動きまで併せて検出する。通信状況把握部301は、予め与えられているビデオプロセッサ30のアンテナの位置と、検出した内視鏡10のアンテナ及び中継器20a~20cのアンテナの位置と、に基づいて、通信経路を検出する。そして、通信状況把握部301は、障害物の動きまで考慮して、通信経路に対して当該障害物が侵入しているかどうかに応じて、当該通信経路の通信状況を把握する。
図8を参照して、第2の実施形態に係る通信制御方法の処理手順について説明する。図8は、第2の実施形態に係る通信制御方法の処理手順の一例を示すフロー図である。
以上説明した第1及び第2の実施形態におけるいくつかの変形例について説明する。なお、以上説明した第1及び第2の実施形態、並びに、以下に説明する各変形例は、可能な範囲で互いに組み合わされて実現されてよい。
以上説明した第1及び第2の実施形態では、図3に示す通信方法決定部303によって、通信経路を、より安定的な通信が可能な通信経路に切り替える処理が行われていた。しかしながら、通信経路の切り替え処理は、通信方法の決定処理の一例である。通信方法決定部303による通信方法の決定処理はかかる例に限定されない。例えば、通信方法決定部303は、通信方法として、内視鏡10とビデオプロセッサ30との間の無線通信に用いられる電波の周波数帯域を決定してもよい。
以上説明した第1及び第2の実施形態では、図2に例示するように、手術室の天井等、手術室内を俯瞰する位置に術場カメラ40が設置されていた。しかし、術場カメラ40の配置位置はかかる例に限定されない。術場カメラ40は、内視鏡10のアンテナ及び中継器20のアンテナを少なくとも撮影範囲に収めるように配置されればよく、その配置位置は任意である。
以上説明した第1及び第2の実施形態に係る通信制御システム1に、通信状況把握部301によって把握された内視鏡10とビデオプロセッサ30との間の通信状況についての情報を、手術室内の医療スタッフに通知する機能が更に設けられてもよい。例えば、ビデオプロセッサ30に、このような通知を行う通知部としての機能が設けられ得る。当該通知部は、通信状況として、例えば、現在用いられている通信経路を医療スタッフに対して通知してもよい。また、当該通知部は、通信状況として、例えば、手術室内に存在する各通信経路を医療スタッフに対して通知してもよい。医療スタッフは、通知されたこれらの情報に基づいて、例えば全ての通信経路が遮断されないように、自身の動きや器具の配置に気を配ることができる。
以上、添付図面を参照しながら本開示の好適な実施形態について詳細に説明したが、本開示の技術的範囲はかかる例に限定されない。本開示の技術分野における通常の知識を有する者であれば、特許請求の範囲に記載された技術的思想の範疇内において、各種の変更例または修正例に想到し得ることは明らかであり、これらについても、当然に本開示の技術的範囲に属するものと了解される。
