Description

一种兼具硬性和软性内镜功能的手术内窥镜 技术领域
本发明涉及一种内镜技术，尤其是一种既适用于微创手术，又适用于开放性手术的内窥镜，具体地说是一种兼具硬性和软性内镜功能的手术内窥镜。
背景技术
目前，微创手术以其创伤小，痛苦小、手术恢复快及成本低深受患者和手术医生的欢迎。但在实际进行的腹腔手术中，经常出现原计划的内镜微创手术(如腹腔镜手术)需要改为开放性手术，此时，微创手术的优点将无法发挥，手术医生需要凭借其经验和肉眼对手术创面进行观察判定。而对于那些原计划就进行开放性手术的医生来说，更无法使用微创手术用的腹腔镜进行手术。也就是说，现有的腹腔镜由于其插入部分较长，在非微创的情况下无法使用，手术医生不能手持长长的腹腔镜进行手术引导。对此，目前尚无好的解决方案，必须加以克服。
发明内容
本发明的目的是针对现有的内窥镜只能适用于微创手术而不能应用到开放性手术中以充分发挥其强大的创面放大及术野清晰优点的问题，设计一种既可用于微创，又可用于开放性手术，尤其适用于微创向开放性手术转换情景的兼具硬性和软性内镜功能的手术内窥镜。
本发明的技术方案是：
一种兼具硬性和软性内镜功能的手术内窥镜，其特征是：外罩壳3与手柄护套17采用可拆卸式结构以便在使用时使整个手术内窥镜既可以是具有硬性内镜功能，又可以通过拆卸掉外罩壳3使之兼具软性内镜功能，硬性内镜功能和软性内镜功能可以进行切换使用。
所述的兼具硬性和软性内镜功能的手术内窥镜包括能任意弯曲定形的波纹管9，工作用线缆4穿过波纹管9与腹腔镜主机21电气连接，波纹管9的前端连接有螺纹管8，螺纹管8中安装有电极板7、传感器6、镜头座2和光源1，镜头5安装在镜头座2上；螺纹管8旋装在外罩壳3的前端中，两端通过内外螺纹实现连接，波纹管9的前端通过螺纹管8实现其在外罩壳3前端的定位，波纹管9的另一端穿过外罩壳3的后端伸入手柄护套17中，外罩壳3的后端设有一个插入端26和凹弧形扣接部3-1，插入端26插入安装在手柄护套17端部的连接座22中，连接座22中内嵌有只能外移的限位球13，限位球13与卡扣14上的内凸台23相抵，从而将限位球13定位在所述的凹弧形扣接部3-1中，实现外罩壳3后端与手柄护套17的可拆卸式连接；卡扣14套装在连接座22上并在轴向导向结构(如轴向 键与槽结构)的作用下只能在连接座22上作轴向移动，在连接座22和卡扣14之间安装有使内凸台23趋向于压紧在限位球上的弹簧16，弹簧16的一端与内凸台23相抵，另一端与连接座22上的外凸台24相抵。
所述的外罩壳3中安装有送气或水的钢管10，钢管10的出口端位置外罩壳3的前端面上，它的进口端位于外罩壳3的尾端并通过气管连接件11与送气或水软管12相连，送气或水软管12与供气或水装置相连通。
所述的连接座22有端部安装有使限位球23内收的箍紧限位环15。
所述的插入端26上设有插入导向键，相应的在连接座22上设有导向槽14-1。
本发明的有益效果：
本发明突破了传统内窥镜(尤其是腹腔镜)只能用于微创手术的局限，解决了普通开放性手术中不能使用内窥镜的难题，无论是微创手术、微创转开放性手术还是计划中的开放性手术均可使用本发明的内窥镜，实现清晰的手术视野在显示器上的显示。
本发明可大大降低手术医生的操作难度，提高手术效率，使术野达到与微创同步的效果。
本发明结构简单，使用方便，在进行微创手术时，只需保护外罩壳与连接座的正常连接即可，当需要进行开放手术时，只需拉动卡扣，使外罩壳与手柄护套分离，取下外罩壳，内窥镜的头部因波纹管的作用可任意弯曲变形和定形。从而使得开放性手术中也能正常使用腹腔镜，提高手术部位的清晰度。
本发明还可在内窥镜微创手术过程中通过外罩壳中自带的冲水、冲气管路对手术部位进行清洁，进一步提高了手术部位的清晰度，使手术医生能清楚地分辨出正常组织与需要手术操作的人体组织，降低手术风险。
本发明使用时既可以是具有硬性内镜功能，又可以通过拆卸掉外罩壳使之兼具软性内镜功能，并且硬性内镜功能和软性内镜功能能进行快速切换使用。

具体实施方式
下面结合附图和实施例对本发明作进一步的说明。
如图1-4所示。
一种兼具硬性和软性内镜功能的手术内窥镜，其关键是外罩壳3与手柄护套17采用可拆卸式结构；使用时既可以是具有硬性内镜功能，又可以通过拆卸掉外罩壳3兼备具有软性内镜功能，并且硬性内镜功能和软性内镜功能可以进行切换使用。
具体而言，整体结构如图4所示，具体结构如图1、2所示，它包括能任意弯曲定形的波纹管9，工作用线缆4穿过波纹管9与腹腔镜主机21电气连接，如图3所示，波纹管9的前端连接有螺纹管8，螺纹管8中安装有电极板7、传感器6、镜头座2和光源1，如图1所示，镜头5安装在镜头座2上；螺纹管8旋装在外罩壳3的前端中，两端通过内外螺纹实现连接，波纹管9的前端通过螺纹管8实现其在外罩壳3前端的定位，波纹管9的另一端穿过外罩壳3的后端伸入手柄护套17中，如图2所示，外罩壳3的后端设有一个插入端26和凹弧形扣接部3-1，所述的插入端26上设有插入导向键3-2，相应的在连接座22上设有导向槽14-1。插入端26插入安装在手柄护套17端部的连接座22中，连接座22中内嵌有只能外移的限位球13，限位球13与卡扣14上的内凸台23相抵，从而将限位球13定位在所述的凹弧形扣接部3-1中，实现外罩壳3后端与手柄护套17的可拆卸式连接；所述的连接座22有端部安装有使限位球23内收的箍紧限位环15。卡扣14套装在连接座22上并在轴向导向结构(如轴向键与槽结构)的作用下只能在连接座22上作轴向移动，在连接座22和卡扣14之间安装有使内凸台23趋向于压紧在限位球上的弹簧16，弹簧16的一端与内凸台23相抵，另一端与连接座22上的外凸台24相抵。
为了微创手术过程中使手术界面更为清晰，具体实施时，最好在所述的外罩壳3中安装一个用于送气或水的钢管10，钢管10的出口端位置外罩壳3的前端面上，它的进口端位于外罩壳3的尾端并通过气管连接件11与送气或水软管12相连，送气或水软管12与供气或水装置25相连通。
本发明的使用方法(以腹腔镜为例，其余内窥镜的使用方法相同)是：
在微创手术状态下，需要将图2的外罩壳3前端的插入部26上的导向键3-2对准连接座22上的导向槽14-1中，同时操作者向后(图中为向左)拉动卡扣14，克服弹簧的单力，使压在限位球13上的内凸台23移离限位球，此时插入部26即可克服阻力，使限位球向外移动，当插入部26上的凹弧形扣接部3-1与限位球相对时，限位球13卡入凹弧形扣接部3-1中，此时松开卡扣14，卡扣14在弹簧16的作用下复位，限位球13被顶死在凹弧形扣接部3-1 中，从而实现了外罩壳3与手柄护套17的硬连接，使用过程中能确保两者不会分开。
当需要在开放性手术状态下使用本发明的腹腔镜时，只需拉动卡扣14，即可将外罩壳3从手柄护套中拨出，实现两者的分离，然后再转动外罩壳3，使其前端的内螺纹与波纹管9前端的螺纹管8分离，将外罩壳3与波纹管9分离，然后根据需要将波纹管9弯曲至所需的角度和位置，操作医生即可手持波纹管9进行图像的获取。当然，在进行外罩壳3与手柄护套17分离前还需要先将送气或水的软管从气管连接件11处分离。
本发明未涉及部分均与现有技术相同或可采用现有技术加以实现。
