Description

硬性内窥镜 技术领域
本发明涉及内窥镜，尤其涉及一种硬性内窥镜。
背景技术
近年来，内窥镜及其手术器械大量的用于微创诊断与治疗领域，随着微创医疗技术的快速发展，对内窥镜提出了更高的要求。按内窥镜所到达的部位不同进行分类：分为神经镜、尿道膀胱镜、电切镜、腹腔镜、关节10镜、鼻窦镜、喉镜等。根据内窥镜头部弯曲情况，可分为软性的可弯曲内窥镜和硬性内窥镜。内窥镜结构可以是重复使用的。
医疗产品特别是与血液和黏膜组织接触的相关产品对一次性使用的要求非常强烈；国内外，有很多在重复内窥镜上套一层皮或套的设计。这种类似设计会有几个问题：1、会增加内窥镜外径；2、拆装复杂，且有有无菌交叉污染的风险；3、只在插入部套皮不能做到与手柄的无菌全隔离。4、在整体内窥镜上套皮，会严重影响使用的操作；5、外皮照明反光会干扰成像。6、外皮会影响内窥镜弯曲角度等等。
反复使用的内窥镜与患者、医疗人员等的接触，因而需对其进行灭菌消毒等处理，然而，由于内窥镜较为复杂，其中的摄像头、光源部件、医疗相关器械等等一般通过封装胶水封装起来，形成封装结构。封装胶水在湿热灭菌多次后，易于造成其结构不再稳定的情况，从而导致封装结构及内窥镜结构的结构不再稳定，会出现内漏使得灭菌效果变不理想的情况。
针对于此，可将内窥镜配置为重复使用，并将其接入一次性使用的结构，此时，内窥镜后端需利用电线传输电能与信号，并在其后端连接灭菌护套。可见，内窥镜虽然被隔离，但与之一起使用的电线并未完全被隔离，内窥镜并未完全被包裹，依旧会带来安全隐患，同时，也会带来不便于操作的问题。
此外，还需指出，新型冠状病毒等病毒有严重的传染性，且感染或待确诊病例众多，如果用一次性电子内窥镜，成本是国家不能承受之重；使 用反复使用内窥镜，面对传染性这么强的病毒安全性又得不到保证；在重复内窥镜上套一层皮或套，设备昂贵数量少、准备时间长、使用不方便，严重影响就诊且安全性也有隐患；因此，还是需要技术上有新的突破的产品。

下面以具体地实施例对本发明的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
图1是本发明一实施例中硬性内窥镜的构造示意图；图2是本发明一实施例中硬性内窥镜的结构示意图。
请参考图1和图2，硬性内窥镜，包括一次性使用的镜体结构1与能够重复使用的摄像组件2。所述镜体结构1可以为已灭菌产品，使用后便可抛弃；所述摄像组件2在手术实施过程前需消毒(酒精擦拭或等离子灭菌等形式)。
所述镜体结构1包括手柄部13、镜体插入部11与线路连接部12。
所述镜体插入部11直接或间接连接于所述手柄部13，所述线路连接部12包括位于所述手柄部13内的母座121，以及位于所述手柄部13外的对外连接部122，所述母座121与所述对外连接部122直接或间接连接，例如可以通过电路板、电线等实现电连接。通过对外连接部122，可实现与其他设备的电连接，例如可以与主机电连接，进而，信号经过主机处理后可成像于显示屏上。
所述手柄部13设有供所述摄像组件2接入的摄像组件接入口131，其通常是沿直线方向接入的；所述摄像组件2接入并装配于所述摄像组件接入口131后能够插接于所述母座121，以利用所述母座121与所述对外连接部122 传输电能和/或信号。
其中的镜体结构1，可理解为配置了母座121与对外连接部122，且能够为所接入的摄像组件2提供隔离环境的任意结构。其也可描述为镜鞘、外鞘等，任意应用于镜体、镜鞘、外鞘的构造均可应用于本实施例而实现镜体结构1的功能。
其中的摄像组件2，可理解为配置了公头与摄像头封装部，且能够通过图像的采集实现内窥的任意结构。
以上所涉及的摄像组件2装配于摄像组件接入口131的结构状态，可理解为摄像组件2接入并到达所需的位置的结构状态，在使用了无菌隔离盖3的情况下，其也可理解为装配完无菌隔离盖3之后的结构状态。
以上所涉及的电能的传输，可例如对摄像组件2中摄像头封装部进行供电，具体举例中，该电能的传输也不排除对照明模块等进行供电的手段；以上所涉及的信号的传输，可例如传输CMOS影像的信号，也可例如传输摄像头封装部的控制信号。
可见，本实施例的以上方案中，在摄像组件接入镜体结构的摄像组件接入口之后，可利用镜体结构的母座与对外连接部对外进行电连接，因此，摄像组件自身可无需直接对外进行电连接，进而，本实施例中的摄像组件可完全被无菌隔离，有效避免或降低安全隐患，同时，由于无需将摄像组件的电线穿过灭菌护套，可便于降低操作的难度。图3是本发明一实施例中摄像组件的结构示意图一；图4是本发明一实施例中摄像组件的部分结构示意图一；图5是本发明一实施例中摄像组件的部分结构示意图二；图6是本发明一实施例中摄像组件的部分结构示意图三。
请参考图3至图6，所述摄像组件2可以包括摄像头封装部23、传导杆24、把手21、设于所述把手21的公头22，以及第一电线25。
所述传导杆24的一端连接所述把手21，其可以是直接连接的，也可以是间接连接的，所述摄像头封装部23设于所述传导杆24的另一端；所述第一电线25穿设于所述传导杆24与所述把手21，所述第一电线25的一端直接或间接连接所述摄像头封装部23，另一端直接或间接连接所述公头22。
其中的第一电线可以指单个电线，也可以包括多个相同或不同的电线，同时，也不排除电线中配置有其他器件的方案。
在所述摄像组件2接入并装配于所述摄像组件接入口131后，所述公头22插接于所述母座121，所述传导杆24穿设于所述镜体插入部11。
其中一种实施方式中，一次性使用的镜体结构在生产制造过程中，镜体插入部11、其摄像通道的长度等均难以精确掌控。
故而，摄像头封装部23可能会难以达到预定位置，例如，无法准确抵达镜体插入部11的尖端从而对前方的图像进行采集，进而，会直接影响或减小影像的视场角大小，减少视野范围。因此，本实施例还引入了弹性补偿结构212，具体的，所述把手21包括把持头211与设于所述把持头211的弹性补偿结构212。
所述弹性补偿结构212的沿所述摄像组件的接入方向(也可理解为沿所述传导杆24的长度方向)的一端直接或间接连接所述传导杆24，另一端直接或间接连接所述把持头211，例如，可经部件盖2122连接于把持头211，进而实现位置的相对固定，所述摄像组件2接入并装配于所述摄像组件接入口131后，所述把持头211相对于所述手柄部13位置固定，例如可在手柄部13内配置相应的定位结构，把持头211接入后可通过定位结构固定其相对于手柄部13的位置。
所述弹性补偿结构212用于在所述摄像组件2接入并装配于所述摄像组件接入口131后利用弹性力直接或间接推动所述传导杆24，以使得所述摄像头封装部23处于所述镜体插入部的尖端，其也可理解为处于所需的位置。
其中，弹性补偿结构212所产生的弹性力可以是弹性部件受力发生形变而产生的克服该形变的作用力，若弹性部件为弹簧，则该形变可例如是拉伸、压缩，若弹性部件为弹片或其他构造，该形变也可以是构造中的部分部件发生运动。
具体实施过程中，所述弹性补偿结构212包括弹性部件2121(例如弹簧)、部件盖2122与部件套2123，所述把持头211的靠近所述摄像头封装部的侧壁(即如图4所示的右侧的侧壁)设有弹性部件通孔，该弹性部件通孔可供弹性补偿结构212中的部分构造穿过，所述弹性部件2121、所述部件盖2122与所述部件套2123均设于所述把持头211的内腔；所述弹性部件2121沿所述接入方向(即摄像组件2接入摄像组件接入口131的直线方向，也可理解为沿所述传导杆24的长度方向)连接于所述部件盖2122与所述部件套2123 之间。
所述第一电线25依次穿过所述弹性部件通孔、所述部件套2123与所述部件盖2122，以图4为例，其可从右至左依次穿过弹性部件通孔、所述部件套与所述部件盖。所述部件套2123相对于所述传导杆24的位置固定，例如两者可以是焊接固定连接的，所述部件盖2122相对于所述把持头211的位置固定，例如两者可以直接或间接固定连接。
具体实施过程中，请参考图6，所述弹性补偿结构212还包括部件座2124，所述部件座穿设于所述弹性部件通孔，所述部件套2123与所述弹性部件2121均位于所述部件座2124的内侧，所述部件盖2122盖合于所述部件座2124的远离摄像头封装部23的一端，进而，部件盖2122相对于部件座2124的位置是固定的，部件座2124相对于把持头211的位置是固定的。
进一步举例中，请参考图6，所述部件座2124包括扁平座体21241与圆筒座体21242，所述扁平座体21241的一端连接所述圆筒座体21242，所述扁平座体21241位于所述把持头外，所述圆筒座体21242穿过所述弹性部件通孔，所述圆筒座体21242的外壁形状与所述弹性部件通孔的内壁相匹配。其中，圆筒座体21242与扁平座体21241可以是一体的，可以是装配在一起的。通过前端的扁平状，在插入一次性镜体时，可起到导向作用。
此外，具体举例中，所述弹性补偿结构212还包括设于部件套2123的对接侧壁的一端设有密封圈2125，其可用于在非工作状态下防止液体进入。
通过以上方案，基于弹性补偿结构，可利用弹性力保障摄像头封装部能够处于所需位置，消除制造和装配的尺寸误差对摄像带来的影响。
具体实施过程中，所述公头22与所述弹性部件通孔设于所述把持头的同一侧壁，进而，通过同一方向的接入运动，可同时实现把持头的接入，以及公头与母座的对接。
所述把持头211的内腔还设有公头电路板26，所述公头电路板26相对于所述侧壁的位置固定，所述第一电线25经所述公头电路板26连接所述公头22。以上方案中，基于电路板实现电连接，可有效保障电连接的稳定。

其中，镜体插入部11与通道管14可以是一体成型的，此时，通道管14也可视作镜体插入部11的插入杆111的一部分，其他举例中，镜体插入部11与通道管14也可以是装配或通过一定的工艺连接在一起的。
所述摄像组件2接入并装配于所述摄像组件接入口131后，所述把手21接入所述导向器15，且所述传导杆24依次穿过所述通道管14与所述镜体插入部11(例如其插入杆111)。同时，母座也可设于导向器15中，通过导向器15，可以对反复使用摄像部的插入起导向作用。
具体实施过程中，通道管14可通过固定座16固定连接手柄部13内，对应的，手柄部13内可设有配合固定座16的构造。进而，通过固定座可便于镜体插入部11(例如其插入杆111)与通道管14的方向和长短，限制器械管、液体管以及电线等在镜体插入部11(例如其插入杆111)内的位置。
具体实施过程中，请参考图7，所述线路连接部12还包括母座电路板124与第二电线123，所述母座电路板124与所述母座电连接，所述母座电路板经所述第二电线123连接所述对外连接部122，以利用所述第二电线123传输电能和/或信号；所述母座电路板124位于所述手柄部13内，所述第二电线123穿过设于所述手柄部的电线穿孔。

此外，以上方案中，母座121与对外连接部122之间，对外连接部122与外部设备(例如主机)之间都是通过有线连接的，在其他可选方案中，若仅需实现信号传输，则母座与对外连接部之间、对外连接部与外部设备(例如主机)之间均也可通过无线的方式来实现。可见，所述对外连接部122可以为有线连接座，也可以为无线通信部件。
图8是本发明一实施例中手柄部的结构示意图。
请参考图8、图2与图7，所述的软性内窥镜，还包括无菌隔离盖3，所述无菌隔离盖3用于在所述摄像组件2接入并装配于所述摄像组件接入口131后盖设于所述摄像组件接入口131。通过无菌隔离盖，可将镜体结构1内隔离。
以图8为例，无菌隔离盖3可以包括隔离盖本体31、连接带33与安装环32，安装环32可连接于镜体结构1(例如其手柄部13)，隔离盖本体31可通过连接带33连接安装环32。
在实施过程中，可将摄像组件2插入镜体结构1内，然后，可通过线路连接部12与相适应的主机连接，完成摄像部2的供电与CMOS影像的传输。在摄像组件2插入镜体结构1后，所述无菌隔离盖3可扣合于镜体部1尾端，使得非灭菌部件完全与医生和病人隔离。
在其他可选方案中，也可不采用可拆卸的无菌隔离盖3，例如可直接将摄像组件2设置于镜体结构1中，在需要抛弃时，可直接抛弃外部的镜体结构1，无需实施相应的拆装过程。进而，可起到便于拆装与丢弃，节约装配时间等积极的技术效果。
图9是本发明一实施例中手柄部的结构示意图；图10是本发明一实施例中头部模块的结构示意图；图11是本发明一实施例中器械管、液体管与头部模块的结构示意图。
请参考图9至图11，所述镜体插入部11包括插入杆111与头部模块112，所述头部模块112设于所述插入杆111的一端，所述插入杆111的另一端连接所述手柄部13，例如：通过通道管14实现连接；
所述头部模块112设有透光片1121与照明模块1122，接入所述镜体插入部的摄像组件能够透过所述透光片1121对外采集图像。
其中的透光片1121可例如玻璃片。
请参考图11，所述插入杆111内可设有摄像通道(未图示)、器械通道(例如器械管1111内所形成的通道)与液体通道(例如液体管1112内所形成的通道)，所述头部模块112穿设有摄像通孔(其可例如透光片后的通孔)、器械通孔1124与液体管通孔1125，所述摄像通道连接于所述摄像通孔的一端，所述透光片设于所述摄像通孔的另一端，所述器械通道连接所述器械通孔的一端，所述液体通道连接所述液体管通孔的一端；
所述手柄部设有用于接入器械的器械接入口132，以及液体口133，所述液体口133连通至所述液体通道，例如液体管1113可自插入杆111导出，并连通至液体口133，所述液体口133设有水阀5，器械接入口132可设有器械嘴4，其可连通器械通道，进而，器械可经器械嘴4与器械通道进入。
其中的照明模块1122可例如是LED模块，其可设置于电路板1123，该电路板1123可设于头部模块112。
具体实施过程中，为了给照明模块1122供电，插入杆111内还可设有照明电线1113，该照明电线可直接或间接连接至线路连接部12(例如母座121)，从而实现对照明模块1122的供电和/或控制。
有关于以上所涉及的插入杆与头部模块，可以采用本领域任意已有或改进的构造，均不脱离本实施例的描述。
综上所述，本实施例提供的硬性内窥镜中，可包括一次性使用的镜体结构与重复使用的摄像组件，在摄像组件接入镜体结构的摄像组件接入口之后，可利用镜体结构的母座与对外连接部对外进行电连接，因此，摄像组件自身可无需直接对外进行电连接，进而，本实施例中的摄像组件可完全被无菌隔离，有效避免或降低安全隐患，由于无需将摄像组件的电线穿过灭菌护套(同时，无菌隔离盖也可以并非是必须的)，进而，可降低操作的难度，便于实现使用、拆装与一次性的抛弃。
此外，本实施例通过公头与母座的插接实现电连接，可起到装配简单的积极效果，同时，母座、对外连接部等整体的一次性使用与抛弃，可起到更便于整体抛弃的积极效果。
可见，使用本实施例所涉及的方案时，可满足新型冠状病毒等具有严重传染性的病毒的医疗场景，有效保障安全性，还可便于使用与抛弃。
进一步可选方案中，基于弹性补偿结构，可利用弹性力保障摄像头封装 部能够处于所需位置，消除制造和装配的尺寸误差对摄像带来的影响。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
