- Laparoscopic surgery generally uses general anesthesia, and all monitoring is complete.
- ECG ECG
- respiration non-invasive blood pressure
- blood oxygen saturation blood oxygen saturation
- pulse pulse
- body temperature invasive blood pressure and end-respiratory monitoring may also be monitored depending on the operation and patient conditions.
- doctors Before the operation begins, doctors usually induce the patient in manual ventilation mode. In manual mode, after injecting the induction drug, the doctor needs to pinch the respiratory bag to drive the patient to breathe. After induction, doctors usually use mechanical ventilation mode to ventilate the patient. The doctor no longer pinches the skin bag with his hands. Instead, the anesthesia ventilator pinches the skin bag with his hands and controls the patient according to the set ventilation mode, respiratory rate, tidal volume or pressure. breathing.
- the anesthesiologist will use sedation, analgesia, muscle relaxants and other drugs to help the patient achieve an ideal anesthesia state. He will also pay close attention to changes in the patient's physiological signs during the operation and adjust the medication in a timely manner.
- Laparoscopic partial liver resection is currently an important method for the treatment of primary and secondary liver tumors.
- the liver tissue is fragile, has abundant blood supply, and has complex blood vessel distribution.
- intrahepatic blood vessels and even hepatic veins are often damaged, resulting in excessive bleeding.
- massive bleeding occurs, the patient faces the risk of serious complications caused by massive blood transfusion.
- How to reduce bleeding during liver resection and ensure smooth operation is a problem that the industry is still studying and solving.
- the key to successful liver resection technology is to control intraoperative bleeding. Hepatic blood flow obstruction and control of low central venous pressure have always been effective methods to control intraoperative bleeding.
- Central Venous Pressure refers to the pressure in the chest where the superior vena cava and inferior vena cava enter the right atrium, and is an indicator of right atrial preload.
- the normal range of CVP is 5 ⁇ 12cmH2O. Under normal circumstances, CVP ⁇ 5 cmH2O often indicates poor right atrial filling or insufficient blood volume.
- Maintaining low central venous pressure is currently mainly achieved clinically through the combined use of anesthetic drugs and antihypertensive drugs, fluid control, patient positioning and other methods.
- Hepatic blood flow occlusion is a commonly used clinical method to control bleeding during liver resection.
- Complete hepatic blood flow occlusion is the classic Pringle method, completely blocking the hepatic artery and portal vein blood flow in the first porta hepatis.
- the interstitial hepatic blood flow occlusion method is commonly used clinically.
- Interstitial hepatic blood flow occlusion generally means that the hepatic portal is blocked for 15 minutes and then opened for 5 minutes. The blocking and opening times can be adjusted according to the time of liver resection, the location of the liver segments and the surgeon's habits.
- the biggest benefit of this method is to prolong the warm ischemia time of the liver, reduce liver ischemia-reperfusion injury, and reduce visceral congestion time. Of course, it also cannot control hepatic venous reflux bleeding.
- the doctor's usual approach is to use an invasive method to monitor the patient's CVP data through the monitor and display it on the monitor. ; and then proceeds to display surgical images of the patient's body through the endoscopic system. Doctors spend most of their time observing the real-time surgical images displayed on the endoscope system display. When they need to know the patient's current CVP information, they turn their attention to the monitor display for viewing. Since the operation takes a long time, the doctor needs to repeatedly switch his eyes to pay attention to the patient's CVP information.
- the monitor is placed at a certain distance from the endoscope system. The doctor needs to turn his head to check when switching his line of sight.
- the monitor As a centralized display device for patients' physiological signs parameters, the monitor has many types of physiological parameters on its display screen, and the corresponding types of physiological parameters need to be displayed according to the user's settings. For scenarios where CVP information needs to be paid attention to, the doctor must first set up the monitor. When doctors check CVP information, they have to look for the area showing CVP among the many physiological parameters displayed on the display screen, which affects the doctor's concentration during surgery.
- the display screen of the monitor is usually small. If it is placed far away from the doctor, it will also cause great inconvenience for the doctor to see the CVP information clearly.
- the chief surgeon during the operation simply asks other doctors, such as the anesthesiologist, to help check the CVP information on the monitor.
- the anesthesiologist will tell the chief surgeon the CVP information in real time, or the anesthesiologist will tell the chief surgeon when there is an abnormality in the CVP. In this way, it also brings a lot of inconvenience to the operation in the surgical scenario where the patient's CVP information needs to be observed simultaneously.

Description
本发明涉及外科诊断领域，具体涉及一种外科手术系统、内窥镜摄像系统及其成像方法。
外科腔镜系统主要包括用于腹腔内检查和治疗的内窥镜，其是一种光源内窥镜，包括腹腔镜、光源系统、气腹机、成像系统等。在完全无痛情况下应用于外科患者，可直接清楚地观察患者腹腔内情况，了解致病因素，同时对异常情况做手术治疗。运用腹腔镜系统技术，医生只需在患者实施手术部位的四周开几个小孔，无需开腹即可在显示屏幕前直观患者体内情况，施行精确手术操作。
腹腔镜技术相对于传统的开腹手术而言具有恢复快，住院时间短，腹部美容好，并发症少的优点。腹腔镜作为微创外科的代表，在外科领域被广泛应用，涉及许多病种和手术，受到患者欢迎，而且随着科学技术的不断进步，手术器械改进创新，腹腔镜的施展空间将会越来越大。
腔镜手术适用范围包含以下几大类：
一、肝胆系统手术
胆囊切除术，胆总管切开取石术，肝脏切除术，肝囊肿开窗引流术，肝脓肿引流术，胆肠内引流术。
二、脾胰疾病手术
脾切除术，脾囊肿开窗引流术，胰腺假性囊肿内引流术，胰腺部分切除术。
三、胃肠外科手术

在进行不同的外科手术时，可能需要联合观察病人的生理体症，以辅助手术过程中的诊断。由于内窥镜摄像系统属于一个独立的系统，医生通常只能在内窥镜摄像系统的显示器上进行手术视野的观察，并从其他设备上，例如监护仪，观察病人的生理体征信息。这使得医生需要反复在不同的设备上切换视觉，影响手术效率。

为了使本发明所要解决的技术问题、技术方案及有益效果更加清楚、明白，以下结合附图和实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
下面介绍一下本申请所涉及的临床背景。
腹腔镜手术一般采用全身麻醉，各项监护完备，除了标准的心电、呼吸、无创血压、血氧饱和度、脉搏、体温外，根据不同手术和病人情况还可能会监测有创血压、呼吸末二氧化碳、麻醉气体、心输出量、脑电双频指数、肌松、中心静脉压等。
在手术开始之前，医生通常会在手动通气模式下对病人进行诱导，在手动模式下，注射完诱导药物之后，需要借助医生手捏呼吸皮囊来驱动病人吸呼。在诱导完之后，医生通常会使用机械通气模式给病人通气，医生不再手捏皮囊，由麻醉呼吸机来代替手捏皮囊，按照设定的通气模式，呼吸率，潮气量或压力来控制病人的呼吸。
在手术过程中，麻醉医生会使用镇静，镇痛，肌松和其它药物使病人达到较理想的麻醉状态，并密切关注病人术中的生理体征变化，及时调整用药。
然而，低中心静脉压的维持对腹腔镜下肝脏手术具有特别的意义。
腹腔镜下肝脏部分切除手术是目前治疗原发性和继发性肝脏肿瘤的一种重要方法。肝脏组织脆弱，供血丰富，血管分布复杂，肝叶切除时常会出现肝内血管，甚至肝静脉受到损伤而致出血较多的情况。大量出血时，又使病人面临大量输血带来严重的并发症的危险。如何减少肝切手术出血及保证手术顺利进行，是当前业界仍在研究解决的问题。切肝技术成功的关键就是控制术中出血，肝血流阻断以及控制低中心静脉压一直是控制术中出血的有效方法。
中心静脉压（Central Venous Pressure，CVP）是指胸腔内上腔静脉和下腔静脉入右心房处的压力，是反应右心房前负荷的指标。CVP的正常范围为5~12cmH2O。正常情况下CVP<5 cmH2O，常提示右心房充盈不佳或血容量不足。
低中心静脉压（LCVP），一般是指CVP<=5cmH2O。即便CVP低到0~4cmH2O水平，通常也不会导致全身低血压，所以可以把CVP降到适宜的范围却不影响动脉血压，不发生低动脉压，这就是低中心静脉压要达到的目标。
低中心静脉压维持目前在临床上主要通过麻醉药物与降压药物联合应用，液体控制，病人体位等几种方法联合应用来实现。
入肝血流阻断是控制肝切手术中出血临床常用的方法，完全入肝血流阻断即经典的Pringle
法，完全阻断第一肝门的肝动脉和门静脉血流。目前临床上常用间隙入肝血流阻断法，间隙入肝血流阻断一般是指肝门每阻断15分钟再开放5分钟。其中阻断和开放的时间可以根据肝切除时间、肝段位置和外科医生的习惯而进行一些调整。这种方法最大的好处是延长了肝脏的热缺血时间，减轻了肝脏缺血再灌注损伤，减轻了内脏淤血时间。当然，它同样也不能控制肝静脉反流性出血。
基于上述临床场景，尤其是在肝切除手术中，当腔镜手术面临需要监测患者CVP时，医生通常的作法是，通过监护仪使用有创方式监测得到患者CVP数据，并在监护仪上显示出来；然后继续通过内窥镜系统显示患者体内的手术图像。医生大部分时间是在观察内窥镜系统显示器上显示的实时手术图像，在需要了解患者当前CVP信息时，则将视线转移到监护仪显示屏上进行查看。由于手术时间较长，医生需要不断重复切换视线，以时刻关注患者的CVP信息。
并且，监护仪作为内窥镜系统外的一个独立设备，其放置的位置与内窥镜系统具有一定的距离，医生切换视线时需要转头查看。
监护仪作为患者生理体征参数的集中显示设备，其显示屏上的生理参数种类较多，并且需要根据用户的设置来显示对应种类的生理参数。这对于需要关注CVP信息的场景下，医生还得先将监护仪进行设置。医生在查看CVP信息时，还得从显示屏上显示的众多生理参数中寻找显示CVP的区域，影响医生手术时的专注力。
监护仪显示屏通常较小，如果其放置的位置与医生距离较远，也给医生看清楚CVP信息带来较大的不便。
有些时候，手术中的主刀医生干脆直接让其他医生，例如麻醉医生帮忙查看监护仪上的CVP信息，由麻醉医生实时将CVP信息告诉主刀医生，或在CVP出现异常时由麻醉医生告诉主刀医生。这样，同样在需要同步观察患者CVP信息的手术场景下，给手术带来了诸多不便。
为解决上述技术问题中的一个或多个，本申请实施例提供了一种外科手术系统，包括内窥镜摄像系统和医疗设备。
如图1所示，为一实施例中，内窥镜摄像系统的架构示意图。内窥镜摄像系统1000包括光源10、导光束20、硬管内窥镜30、光学卡口40、摄像头50、通信线缆81、摄像主机60、显示器70和视频连接线82。
摄像主机60通过通信线缆81与摄像头50连接，摄像头50获得的图像信号通过通信线缆81传输到摄像主机60进行处理。在某些实施例中，通信线缆81可以为纯电通信线缆、纯光通信线缆或光电复合通信线缆。当通信线缆81包括光通信线缆时，例如光纤；摄像头50将图像信号（电信号）转成光信号，由通信线缆81传输到摄像主机60，摄像主机60再将光信号转成电信号。或者在另一实施例中，通信线缆81与摄像主机60通过电信号接口连接，通信线缆81在与摄像主机60连接的一端先将光信号转成电信号，再通过电连接器将电信号传输至摄像主机60。摄像主机60通过视频连接线82与显示器70连接，用于将视频信号发送到显示器70进行显示。又例如，在其他实施例中，摄像头50与摄像主机60为无线信号传输，而非通过通信线缆81进行通信连接。
本领技术人员应当理解的是，图1仅是内窥镜摄像系统1000的示例，并不构成对内窥镜摄像系统1000的限定，内窥镜摄像系统1000可以包括比图1所示更多或更少的部件，或者组合某些部件，或者不同的部件。例如，内窥镜摄像系统1000还可以包括扩张器、烟雾控制装置、输入输出设备、网络接入设备等。又例如，图1示出的硬管内窥镜30和摄像头50为光学硬管镜，图像传感器设置于摄像头50内；在其他实施例中，硬管内窥镜30和摄像头50可以为集成式的电子内窥镜（例如3D电子内窥镜），其图像传感器设置于硬管内窥镜30的头端。
光源10用于向待观察部位100提供照明光源。所述照明光源包括可见光照明光源和对应于荧光试剂的激光照明光源（例如近红外激励光）。
在本实施例中，光源10包括可见光光源和对应于荧光试剂的激光光源。可见光光源为LED光源。在一实施例中，可见光光源可分别提供不同波长范围的多个单色光，例如蓝光、绿光、红光等。在其他实施例中，可见光光源还可以提供所述多个单色光的组合光，或者是宽光谱的白光光源。所述单色光的波长范围大致为400nm至700nm。激光光源用于产生激光。所述激光例如是近红外激励光（Near
Infrared；NIR）。例如，所述激光的峰值波长可以取780nm-808nm范围内至少任意1个值。光源10可向待观察部位同时提供连续的可见光和对应于荧光试剂的激光，或者向待观察部位分时提供可见光和激光。
其中，采用内窥镜摄像系统1000进行荧光成像之前，在待观察部位100中通过静脉或皮下注射方式引入造影剂，例如吲哚菁绿（Indocyanine
Green；ICG），以便对用标准可见光成像技术不容易看到的组织结构和功能（例如脉管中的血液/淋巴液/胆汁）成像。ICG俗称靛氰绿、诊断用绿针、吲哚花青绿，其是目前在心血管系统疾病临床诊断中常用的一种造影剂，广泛应用于脉络膜和视网膜血管成像。当待观察部位100中的造影剂吸收所述激光光源产生的对应于荧光试剂的激光后可产生荧光。
本申请实施例中，医疗设备可以是一台医疗监护设备（例如监护仪）。申请号为PCT/CN2018/123093的国际专利申请公开了一种医疗监护设备的架构示意图（参见该专利申请的附图3），以及一种对CVP趋势图的显示方案，该专利申请的全部内容通过引用的方式并入本申请中。通常的，CVP的测量方式为有创测量，其通过医疗监护设备的传感器附件进行测量。本申请实施例中，医疗设备对CVP的测量方式可选择现有技术中的任意方式，本申请不对此做详细说明。
本申请实施例中，内窥镜摄像系统与医疗设备直接或间接通信连接。医疗设备包括中心静脉压测量装置，中心静脉压测量装置用于获取患者的中心静脉压数据；内窥镜摄像系统用于采集患者待观察部位的图像信号，生成患者待观察部位的可视图像，并对可视图像进行显示；还用于从医疗设备获取中心静脉压数据，并基于中心静脉压数据显示患者中心静脉压信息。
内窥镜摄像系统从医疗设备处获取到患者的中心静脉压数据，并显示患者待观察部位的可视图像和中心静脉压信息，相当于将两种信息在同一系统上进行显示，方便用户对两种信息的观察，而不需要分别从内窥镜摄像系统上观察患者待观察部位的可视图像，从医疗设备上观察患者的中心静脉压信息，解决了现有技术中手术效率低，用户操作不便的问题。
下面对内窥镜摄像系统的一些可行实施例做进一步说明。
本申请实施例还提供了一种内窥镜摄像系统，包括光源、操作部、图像处理设备和显示器。
光源用于向患者待观察部位提供照明光，例如图1中所提及的光源10。
操作部与光源通过导光束连接，用于通过导光束将光源发出的照明光导向至患者待观察部位，并采集患者待观察部位的图像信号。本实施例中，操作部可以包括图1中的硬管内窥镜30和摄像头50，这些部件在本实施例中，统一称为操作部。
图像处理设备（例如图1中的摄像主机60）与操作部通信连接，用于从操作部获取图像信号进行处理；图像处理设备包括一外部设备通信接口，用于与一医疗设备直接或间接通信连接，以从医疗设备获取所述患者的中心静脉压数据。

在一实施例中，医疗设备为监护仪（例如床旁重症监护仪），监护仪可通过传感器附件进行有创CVP测量。此时，图像处理设备可与监护仪直接通信连接。图像处理设备还可以通过监护中央站与监护仪间接通信连接。监护中央站通常作为整个科室或整个医院监护仪数据的集中地，可对所有监护仪的数据进行汇总监控。监护中央站与监护仪可以通过局域网通信连接，以获取监护仪的设备信息和/或其测量的病人数据；在另一些实施例中，监护中央站还可以与呼吸机、输液泵等其他医疗设备进行通信连接，以获取对应的设备信息和/或病人数据。本申请实施例中，监护中央站从监护仪中获取CVP数据。在其他实施例中，图像处理设备可通过任意之外的一医疗设备与监护仪间接通信连接，只需要能够从监护仪处获取CVP数据即可。
图像处理设备的外部设备通信接口可以包括有线网络接口和无线网络接口。有线网络接口包括以太网接口，例如RJ-45、SC光纤接口等；无线网络接口包括蓝牙模块、WIFI模块、4G通信模块等。图像处理设备可以通过外部设备通信接口以相应的通信方式与医疗设备通信，以获取CVP数据。
需要说明的是，本申请实施例中，CVP数据可以包括CVP的原始信号，CVP测量值及其相关的信息数据。显示器显示的CVP信息基于CVP数据生 成，其可以包括CVP数据中的部分或全部，例如CVP实时测量值、CVP趋势图、CVP变化量、CPV变化量趋势图等。即可以理解为CVP信息可以是由CVP数据直接得到或经过处理后得到的用于显示的信息。
本申请实施例中，可视图像包括内窥镜摄像系统对患者待观察部位成像的白光图像、荧光图像（纯荧光图像或白光荧光叠加图像）中的至少一种，以及可视图像包括对患者待观察部位成像的二维图像、三维图像中的至少一种。对于内窥镜的摄像系统来讲，可以由用户选择显示白光图像或荧光图像，或者选择显示二维图像或三维图像。
在一实施例中，显示器还用于基于显示信号同时显示患者待观察部位的可视图像和患者的中心静脉压信息。
如图2所示，为在显示器上同时显示患者待观察部位的可视图像201和患者的CVP实时测量值202。具体的，可视图像可以是二维白光图像。
图2所示的实施例中，显示器用于将CVP信息叠加到可视图像上进行显示。
如图3所示，在另一实施例中，显示器用于将中心静脉压信息202和可视图像201分别显示在不同的两个显示区域内。
在一实施例中，图像处理设备还用于通过外部设备通信接口从医疗设备中获取患者的心率信息、血压信息（区别于CVP的血压信息）、心排量信息、病史数据信息中的至少一种；显示器还用于将心率信息、血压信息、心排量信息、、病史数据信息中的至少一种与中心静脉压信息和可视图像同时显示。
如图4所示，其显示了内窥镜摄像系统的可视图像201、CVP信息202和心率信息203。
在一些实施例中，心率信息、血压信息、心排量信息可以通过医疗设备自己的传感器附件测量得到，也可以从之外的其他医疗设备中获取到这些信息。病史数据信息可以由用户在医疗设备中输入得到，也可以从之外的其他医疗设备（例如医院信息系统）中获取得到。
如图5所示，在一实施例中，显示器包括第一显示器501和第二显示器502，第一显示器501用于显示中心静脉压信息，第二显示器502用于显示可视图像。当然，在一些实施例中，第一显示器501还可以用于同时显示心率信息、血压信息、病史数据信息中的至少一种。
在一实施例中，图像处理设备还用于基于预先配置的报警条件，在确定到中心静脉压数据满足报警条件时，输出报警提示信息。如图6所示，其展示了CVP报警信息601。具体的，报警条件可以是CVP实时测量值低于4cmH2O。通过在内窥镜摄像系统中进行CVP报警可以更加直观了让用户了解患者当前的CVP信息，避免用户需要分心关注医疗设备上的CVP报警信息。报警提示信息可以是显示在显示器上的闪烁的文字，报警提示声音等。应当理解，除了图像处理设备将报警提示信息输出到显示器进行展示外，还可以由图像处理设备直接展示报警提示信息，例如由图像处理设备直接展示报警提示声音。另外，报警提示信息包括表征出现报警的信息，也可以包括针对该报警的处置建议信息。
在一实施例中，操作部还包括人机交互界面，用于获取用户输入的操作指令，以关闭或开启中心静脉压信息的显示。如图7所示，为一实施例中操作部的结构示意图，人机交互界面包括设置在操作部上的物理按键701，可用于获取用户输入的操作指令。例如，其中一按键用于由用户按下后关闭或开启CVP信息的显示。本实施例中，用户可以自主控制CVP信息的显示与否，方便在不需要显示CVP信息的场景下关闭CVP信息的显示，以避免干扰对内窥镜摄像系统可视图像的观察。在其他实施例中，人机交互界面还可以是其他可实现人机交互的硬件，例如触控屏、语音控制模块等。在一些实施例中，操作部可以包括前端用于插入患者体内的插入部和后端用于握持的握持部，插入部与握持部可以集成为一个整体，也可以如图1所示通过光学卡口40可拆卸地连接。通常的，操作部需要获取患者待观察部位的图像光，并通过图像传感器将图像光转换成图像信号。图像传感器可以是一个或多个，其可以设置在插入部的前端，也可以设置在握持部内。
在一实施例中，可视图像至少包括内窥镜摄像系统对患者待观察部位成像的三维图像；图像处理设备还用于在获取到中心静脉压数据后，对中心静脉压数据进行符合三维图像观察的视差处理，以使显示的中心静脉压信息与三维图像具有匹配的视差。本实施例中，由于可视图像为三维图像，通常的，用户在观察三维图像时需要佩戴3D眼镜，方能观察到三维图像。但是，由于内窥镜摄像系统从医疗设备上获取的CVP数据并不是三维信息，因此，为了使得用户在佩戴3D眼镜的情况下，依然能够观察到清晰的CVP信息，图像处理设备需要对CVP数据进行视差处理，使得用户佩戴3D眼镜时能同时观察到清晰的三维图像和CVP信息。
在一实施例中，图像处理设备还用于确定内窥镜摄像系统当前执行的手术类型，并基于手术类型确定关闭或开启中心静脉压信息的显示。使得用户可以在需要的手术场景下（例如肝切除手术）观察到CVP信息上，在不需要的手术场景下，图像处理设备能够不显示CVP信息，避免产生不必要的干扰。
在一实施例中 ，图像处理设备还用于确定内窥镜摄像系统当前执行的手术类型为肝切除手术时，开启中心静脉压信息的显示。由于肝切除手术通常需要通过观察患者的CVP来进行肝阻断操作，因此，在肝切除手术场景下，开启中心静脉压信息的显示尤有必要。
在一实施例中，图像处理设备用于确定内窥镜摄像系统当前执行的手术类型，包括：图像处理设备用于识别由用户设置的关于手术类型的配置信息，以确定内窥镜摄像系统当前执行的手术类型。通常的，用户在进行内窥镜手术前，可以在图像处理设备上选择对应的手术类型，此时，图像处理设备可以根据用户选择的手术类型，自动确定是否开启CVP信息显示功能。
在一实施例中，图像处理设备用于确定内窥镜摄像系统当前执行的手术类型，包括：图像处理设备用于从图像信号中识别患者待观察部位的图像特征，以确定内窥镜摄像系统当前执行的手术类型。例如，在肝切除手术场景下，显示CVP信息具有更高的临床价值，此时，图像处理设备可以识别患者待观察部位的图像特征，例如识别到肝脏器官，则确定当前手术可能为肝切除手术，则自动开启CVP信息显示功能。
如上文所述，对于间隙入肝血流阻断法，医生通常需要对血流阻断时间进行计时。因此，在一实施例中，操作部还用于获取用户输入的启动计时指令；图像处理设备还用于从操作部获取到启动计时指令时执行计时程序，并基于计时程序将计时信息发送至显示器；显示器还用于显示计时信息。如图8所示，801为显时的计时信息。用户可以通过操作部上的物理按键输入启动计时指令。通过在内窥镜摄像系统上增加计时功能，可以更加方便用户在特定手术场景下进行手术，用户只需要观察内窥镜摄像系统的显示器即可了解到所有需要关注的所有信息。
如图9所示，本申请实施例还提供了一种外科手术系统，包括内窥镜摄像系统901和医疗设备902，医疗设备902包括中心静脉压测量装置903，中心静脉压测量装置903用于获取患者的中心静脉压数据。内窥镜摄像系统用于采集患者待观察部位的图像信号，生成患者待观察部位的可视图像，并对可视图像进行显示；还用于从医疗设备获取中心静脉压数据，并基于中心静脉压数据显示患者中心静脉压信息。
在一实施例中，中心静脉压测量装置903可以通过有创的方式测量患者的CVP数据。
在一些实施例中，内窥镜摄像系统901可以采用上述任意一实施例中提供的内窥镜摄像系统。
在另一些实施例中，内窥镜摄像系统901也可以采用区别于上述实施例中提供的内窥镜摄像系统。例如，内窥镜摄像系统901的显示器设置有外部设备通信接口，用于与医疗设备直接或间接通信连接，以从医疗设备获取所述患者的CVP数据。显示器同时内窥镜摄像系统的图像处理设备通信连接，以获取图像处理设置输出的显示信号；显示器基于该显示信号和获取的CVP数据，显示患者待观察部位的可视图像和患者的CVP信息。当然，显示器也可以直接从医疗设备获取CVP信息的显示信号，直接根据获取到显示信号进行显示。但需要说明的是，CVP数据应当理解为设备之间进行传输的数据，CVP信息应当理解为显示器显示的信息。
也就是说，在不同实施例中，内窥镜摄像系统901可以通过不同的设备来实现与医疗设备的通信，只需要将获取到的CVP数据最终显示到内窥镜摄像系统901的显示器上即可，本申请不再对这些可行的方案进行一一列举，本领域普通技术人员在上述记载的实施例的基础上，能够给予适当的变形，以解决同样的技术问题。
