具体实施方式
如图1～13所示，本发明主要包括两部分，其中一部分是经过改造的内窥镜1，如图3所示，内窥镜镜体头端部1.1侧面设有开口，抬钳器1.2置于开口内，在内窥镜镜体头端部1.1远离所述开口的一侧设有观察窗口1.3和光学照明窗口1.4；本发明的另一部分是一次性耗材2，如图4～13所示，所述一次性耗材2将多次使用的内窥镜1保护起来不受污染，所述一次性耗材2不仅设有套囊2.4和端帽2.1保护内窥镜1外表面，如图11～12所示，还有一次性钳道管2.6置于内窥镜1镜体管道内保护内窥镜1内表面，保护内窥镜1外表面的套囊2.4和保护内窥镜1内表面的一次性钳道管2.6通过所述端帽2.1连为一体，将内窥镜1从里到外进行了全面保护，在端帽2.1与内窥镜镜体头端部1.1之间设有装有透明液体的胶丸2.2，所述胶丸2.2通过端帽2.1与内窥镜镜体头端部1.1共同作用碎裂，所述胶丸2.2碎裂后，胶丸2.2内的透明液体充满端帽2.1与内窥镜镜体头端部1.1上的观察窗口1.3和光学照明窗口1.4之间的空隙。
现结合附图对护套内窥镜结构说明如下：
如图4～13所示，所述一次性耗材2包括端帽2.1、水气管2.3、套囊2.4、软接口2.5和一次性钳道管2.6，其中端帽2.1套在内窥镜镜体头端部1.1上，所述端帽2.1整体为透明弹性材料制成，如图11～12所示，在端帽2.1侧面设有与内窥镜镜体头端部1.1上的手术管道开口形状一致的长条状开口，在所述长条状开口内设有软接口2.5，所述软接口2.5为弹性薄膜制成且为烟斗状，所述软接口2.5的大口端外缘与端帽2.1上的长条状开口内侧粘接密封，软接口2.5小口端套在一次性钳道管2.6远端外壁一定距离处并粘接，端帽2.1通过所述长条状开口内的软接口2.5与一次性钳道管2.6相连，端帽2.1敞口端与套囊2.4连接，所述套囊2.4与所述端帽2.1相连将内窥镜1外表面保护，在套囊2.4与内窥镜镜体头端部1.1之间设有水气管2.3，如图5所示，在端面2.1端部内壁与内窥镜镜体头端部1.1之间设有胶丸2.2，如图11～13所示， 活检钳3依次穿过一次性钳道管2.6和内窥镜镜体头端部1.1，最后由软接口2.5伸出。
如图3～13所示，所述内窥镜1包括内窥镜镜体头端部1.1、抬钳器1.2和拉丝1.5，内窥镜镜体头端部1.1侧面设有开口，抬钳器1.2置于所述开口内，所述抬钳器1.2通过拉丝1.5作用抬起，如图11～13所示，当抬钳器1.2与拉丝1.5处于放松状态时，抬钳器1.2与软接口2.5不发生相互作用，活检钳3通过软接口2.5从端帽2.1上的长条状开口斜向伸出；当拉紧拉丝1.5使抬钳器1.2抬起时，软接口2.5产生相应变形，并隔着软接口2.5推动一次性钳道管2.6抬起，从而间接调整活检钳3的抬起，调整其指向，从而对特定部位进行钳取操作。
在本发明中为增加端帽的透光性能，提高照明的效率，避免杂光干扰，在端帽2.1与内窥镜镜体头端部1.1上的观察窗口1.3和光学照明窗口1.4相对应的下侧面2.7处设有光窗，该光窗大小与内窥镜镜体头端部1.1上的观察窗口1.3和光学照明窗口1.4一致并采用光学级材料密封，用以保证物体成像的清晰度和照明的透光度。
本发明的端帽2.1前端内壁采用不同结构放置胶丸2.2，并通过不同方式使胶丸2.2碎裂。
实施例1
如图5～7所示，本实施例中，端帽2.1的前端立面与下侧面2.7之间的连接处为一斜面，在该斜面上设有凹坑2.8，胶丸2.2放置于所述凹坑2.8内并通过粘接的方式固定，所述端帽2.1的前端立面与下侧面2.7连接处的斜面与内窥镜镜体头端部1.1配合挤压胶丸2.2，如图5～6所示，所述内窥镜镜体头端部1.1前端面靠近所述下侧面2.7的一侧设有倾斜一定角度的斜面，当内窥镜镜体头端部1.1与端帽2.1配合挤压胶丸2.2时，所述内窥镜镜体头端部1.1的斜面与所述端帽2.1的前端立面与下侧面2.7连接处的斜面共同作用将胶丸2.2挤碎，使胶丸2.2内的透明液体顺着端帽2.1的下侧面2.7流动到所述观察窗口1.3和光学照明窗口1.4与端帽2.1上的光窗之间的间隙内。
实施例2
如图8～10所示，本实施例与实施例1的不同之处在于：在端帽2.1的前端内壁设有一个凸台2.9，在内窥镜镜体头端部1.1前端设有一个空心针1.6，胶丸2.2通过粘接的方式固定于所述凸台2.9上并通过所述空心针1.6扎破。
如图8～9所示，在内窥镜镜体头端部1.1内靠近观察窗口1.3和光学照明窗口1.4的一侧设置一个空心针1.6，在内窥镜镜体头端部1.1内与胶丸2.2同轴心位置加工一个锥形凹坑，在所述锥形凹坑底部设有盲孔和通孔2.10，其 中盲孔的一端与所述锥形凹坑相通，盲孔的另一端与所述通孔2.10相通，所述通孔2.10的作用在于使毛刺液体能够流至端帽2.1的下侧面2.7上，将空心针1.6尖朝外安装到所述盲孔内，需保证空心针1.6的针尖不超过所述锥形凹坑的大端平面，即使空心针1.6始终处于所述锥形凹坑内，固定好空心针1.6后，在空心针1.6的尾端加工出所述通孔2.10，所述通孔2.10倾斜设置并指向内窥镜镜体头端部1.1设有观察窗口1.3和光学照明窗口1.4的平面，当端帽2.1与内窥镜镜体头端部1.1配合时，利用内窥镜镜体头端部1.1上的空心针1.6将胶丸2.2扎漏，使胶丸2.2内的透明液体顺着空心针1.6内的针孔流至空心针1.6尾端，再顺着所述通孔2.10流至到所述观察窗口1.3和光学照明窗口1.4与端帽2.1上的光窗之间的间隙内。
