Description

内窥镜连接装置及内窥镜*** 技术领域
本发明属于内窥镜技术领域，涉及一种内窥镜连接装置及内窥镜***。
背景技术
在医疗领域中广泛应用的内窥镜***包括内窥镜镜体、处理器和冷光源，其构成方式有两种：方式一，处理器和冷光源单独布置，镜体与处理器、冷光源分别连接；方式二，将处理器和冷光源组成内窥镜主机，再将镜体与内窥镜主机连接。
方式一的结构如图1所示，镜体1’与冷光源3’在接头4’处连接，处理器2’通过数据连接线5’与镜体1’连接，处理器2’与数据连接线5’之间具有接头，数据连接线5’与镜体1’之间也具有接头，其连接接头较多，降低了内窥镜***的可靠性。
方式二的结构如图2所示，处理器和冷光源集成在内窥镜主机6’的内部，镜体1’与内窥镜主机6’在接头7’处连接，由于只有一个接头，相较方式一提高了内窥镜***的稳定性。但方式二存在以下问题：若采用无线供电，由于供电线圈和控制电路板的体积较大导致接头7’的体积增大，操作时需要较大的插拔力，操作不方便，可靠性低。为了防止镜体从主机上脱落，一般设置有不易操作的锁紧结构，对镜体的连接与拆卸不方便，操作困难。

接触式供电部包括冷光源侧隔离电源以及与所述隔离电源连接的接触式供电插座/接触式供电插针，还包括镜体侧接触式供电插针/接触式供电插座及与其连接的电源单元。
本发明采用接触式供电方式供电，不存在电磁泄露风险，结构尺寸小，有利于实现连接器小型化。本发明采用两路光信号传输通路分别传输图像信息和控制信息，实现了信号传输与供电的分离，信号的抗干扰能力强。
在本实施方式中，该接头还包括照明光接口101和气体提供接口301，电子内窥镜冷光源通过照明光接口101和气体提供接口301向内窥镜镜体提供照明光和工作气体。如图18所示，从镜体侧看，该接头(即镜体侧连接器)上设置有照明光接口101，图像信息光接口201，气体提供接口301，供电接口501，信号光接口401。所有接口设置于同一接头上，实现了连接器的小型化，且所有接口一次连接完成，插接方便。
本发明还提供了一种电子内窥镜镜体，如图19所示，其包括镜体头端电路、操作把中继电路、以及导光部数据转换电路。其中，镜体头端电路包括传感器和并串数据转换单元，传感器采集图像信号并传输给并串数据转换单元，并串数据转换单元将并行数据转变为串行数据并输出给导光部数据转换电路。
操作把中继电路包括时钟单元和电源单元，时钟单元控制传感器的采集频率，电源单元至少为镜体头端电路和操作把中继电路供电，具体可将镜体头端电路中的串并数据转换单元与导光部数据转换电路的串并数据转换单元连接，实现数据传输(图中没有示出)。图19中是另一种连接方式，镜体头端电路经过操作把中继电路再与导光部数据转换电路连接。
导光部数据转换电路包括串并数据转换单元、处理器、存储器和本发明的电子内窥镜接头镜体侧的结构，串并数据转换单元接收串行的图像数据转换为并行数据并传输给处理器进行视频格式转换，镜体信息和视频数据发送给第一光信号传输通路的光电转换模块，第二光信号传输通路的光电转换模块的输出信号连接处理器，光电转换模块用于接收电子内窥镜图像处理器发送的控制信 号。

处理器进行视频格式转换，具体可以但不限于采用现有的数据转换器将数字图像数据转换为传输数据。。
如图19所示，在本发明的一种优选实施方式中，由于镜体头端硬质部空间小，能够放下的电路元器件很少，传感器出来的MIPI图像信号经过并行数据转串行数据SLVS信号送出，传感器的控制及时钟信号、电源由操作把中继电路提供。头端视频信号SLVS的波特率超过2Gbps，视频信号经过高速线缆传输到操作把中继板。
操作把中继电路将SLVS信号转换成LVDS信号，操作把中继电路还包括均衡模块(Equalizer)和预加重模块(Emphasizer)，所述镜体头端电路的并串数据转换单元将并行数据转变为串行数据并输出给操作把中继电路均衡模块，所述均衡模块将数据均衡处理后传输给预加重模块，预加重模块加重之后传输给导光部控制电路的串并数据转换单元。均衡的目的是为了让数字信号的眼图更好，这样数据接收端能降低误码率。在数据流中，数字信号有0101组成的信号传输，当出现0101这种数据时，数字信号方波的频率与波特率相等，但是当出现0011这种数据时，数字信号方波的频率只有波特率的一半；由于传输信号 的线缆有带宽限制，频率越高的信号衰减越大，因此数据中的高频信号衰减幅度将比低频信号大。预加重的目的就是将高频信号的幅度增加，抵消高频部分在传输过程中的比低频信号更多的衰减。操作把中继板将视频信号均衡和预加重之后送出，经过线缆连接到导光部控制板。
在本实施方式中，均衡模块和预加重模块为一体设置，具体可以但不限于采用DS25BR100T，其与并串数据转换单元、串并数据转换单元的连接方式可采用通用的连接方式。

在本发明的一种更加优的实施方式中，导光部控制板的具体实施方案为：导光部控制板由FPGA将视频信号进行解串及视频格式转换，同时按键信号、镜体信息和视频数据进行编码通过FPGA的GTP接口送出到光电转换模块。光接收模块的输出信号连接到FPGA上，光接收模块接收由电子内窥镜图像处理器发送的传感器寄存器配置信息及白平衡参数等控制信号。FPGA接收到的传感器寄存器配置信息通过I2C总线配置传感器寄存器，接收到的白平衡参数写入导光部存储器(EEPROM)。EEPROM还用于存储镜体信息，例如镜体序列号、生产制造信息、镜体规格参数等数据。整个电子内窥镜镜体的供电由电子内窥镜冷光源通过接触式连接器提供。
本发明的电子内窥镜和电子内窥镜冷光源之间的连接为绝缘，供电电源通 过隔离电源提供给电子内窥镜。电子内窥镜和电子内窥镜冷光源之间的光通信接口有光准直模块，降低光传输损耗。
通过本发明的硬件方案能降低电子内窥镜通信的误码率，特别是能够降低连接器的数量，提高可靠性。同时电子内窥镜***的抗扰能力大大提升。
本发明还提供了一种电子内窥镜冷光源，如图19所示，其包括光源模块和气体供应模块，还包括本发明所述的电子内窥镜接头镜体冷光源侧的结构。电子内窥镜冷光源的第一光纤连接口接收镜体侧电光转换模块输出的光信号，通过光纤传输到光纤连接器并输送给电子内窥镜图像处理器。电子内窥镜冷光源的连接器与电子内窥镜图像处理器的控制信号输出端连接，控制信号通过第二光信号传输通路的光电转换模块将电信号转成光信号通过第二光纤接口输出给镜体侧光电转换模块。电子内窥镜冷光源的隔离电源连接有接触式供电插座/接触式供电插针，工作时，所述接触式供电插座/接触式供电插针与镜体侧接触式供电插针/接触式供电插座连接。

具体地，在本发明的一种优选实施方式中，第一光纤连接口接收来自电子内窥镜的编码的光信号，再通过光纤传输到光纤连接器送出。来自电子内窥镜图像处理器的控制信号TX接到冷光源的连接器上，控制信号通过光电转换模块将电信号转成光信号通过第二光纤接口送出。电子内窥镜的电源信号由电子内窥镜冷光源通过隔离电源模块提供，通过接触式供电插座输出。
本发明还提供了一种电子内窥镜***，如图19所示，其包括本发明所述的电子内窥镜镜体，本发明所述的电子内窥镜冷光源，以及电子内窥镜图像处理器。其中，电子内窥镜镜体与电子内窥镜冷光源通过本发明的电子内窥镜接头 连接。电子内窥镜图像处理器的光电转换模块将接收到的光信号转成电信号，并传输给显示界面进行显示。
从镜体头端图像传感器采集图像到送到显示器显示，传输距离较远，有的甚至大于6米，且传输速率较高，对抗扰能力要求很高，本发明有效解决远距离高抗扰的硬件解决方案。
在本实施方式中，冷光源与电子内窥镜图像处理器之间具有两路传输通道(具体可以为但不限于RS-422传输通道)；利用第一路传输通道，图像处理器向冷光源发送测光值，冷光源控制器接收到测光值之后经过计算，控制恒流开关电源输出的电流值，调整LED光源的光通量输出；利用第二路传输通道，电子内窥镜冷光源向图像处理器发送冷光源的故障信息，具体是接到ARM上，用于电子内窥镜冷光源向图像处理器发送冷光源的故障信息，ARM接收到的信息通过显示器显示。采用两路能够降低光源调整响应时间，能够使画面亮度更快达到设定的亮度值，不至于长时间过暗或者过亮。通过两路缩短了图像处理器和冷光源之间的通信链路，使冷光源能更快的响应图像处理器发出的调光响应，缩短画面过亮或者过暗的时间。加入镜体在位检测机制能够减少操作者手动上电或者断电的操作步骤。
在本实施方式中，图像处理器向冷光源发送测光值，冷光源控制器接收到测光值之后经过计算，控制恒流开关电源输出的电流值，调整LED光源的光通量输出。
在公开号为CN 109247905 A为本公司之前申请的专利中提出一种检测镜体***的方法，该方法可以在该***中使用。当冷光源MCU检测到电子内窥镜***信号HotPlug，MCU使能隔离电源信号PWR_EN，MCU上报FPGA镜体就位信息，FPGA准备译码图像信号。当镜体从电子内窥镜冷光源中拔除时，HotPlug置高， MCU检测到HotPlug置高，将PWR_EN置低，关闭电子内窥镜电源。
如图19所示，电子内窥镜图像处理器用于图像信号的处理及控制信号的发出，图像显示等功能。光电转换模块将接收到的光信号转成电信号，送入FPGA的GTP接口，FPGA将视频数据和按键信号、镜体信息等信息分离，除视频信号外的信号通过UART发送给ARM，视频信号经过一系列的处理之后通过PCIe发送给ARM。ARM将接收到的视频信号加上UI界面信息送到显示器显示，接收到的按键信号根据按键定义进入到相应的处理界面，接收到的镜体信息送到显示器进行显示。同时ARM接收外接接口设备发出的控制指令进行相应的处理。
