技术领域technical field

本发明涉及一种内视镜头转向结构，特别涉及一种内视镜的可往四个方向转动的可挠性软管结构。The invention relates to a steering structure of an endoscope lens, in particular to a flexible hose structure of an endoscope that can rotate in four directions.

背景技术Background technique

内视镜的发明，使得人类得以更准确的观察物体内部，例如应用于医疗领域，则可进行食道、胃和大肠部位的检验，让医生可藉由内视镜的影像，准确判断病灶的种类和病情发展的程度；如应用于工业领域，则可准确的检查如引擎内部，或是检查区域空间狭小、难以观察的地方，而为了更精确观察多个方位的影像，现今的内视镜其内视镜头处设置有可挠性结构，使得内视镜头具有转向的功效，然而目前的可挠性结构，多为使用环状金属与铆钉的组合，或是使用弹簧等等，如中国台湾名称为【内视镜摆头装置】的新型专利第M352352号披露了一种内视镜摆头装置，该内视镜摆头装置包含摆头机构、弹性组件、支撑部、第一线体、第二线体及双向可挠体，藉由上述组件的组合可使得内视镜具有转向的功效，然而此种内视镜摆头装置在使用上仍有如下若干问题需要克服：The invention of the endoscope allows humans to observe the interior of objects more accurately. For example, in the medical field, it can perform inspections on the esophagus, stomach and large intestine, allowing doctors to accurately determine the type of lesion through the images of the endoscope and the degree of disease development; if it is applied in the industrial field, it can accurately inspect the inside of the engine, or inspect the narrow space of the inspection area, which is difficult to observe. In order to observe images in multiple directions more accurately, today's endoscopes There is a flexible structure at the inner viewing lens, so that the inner viewing lens has the function of turning. However, the current flexible structure mostly uses a combination of ring metal and rivets, or uses springs, etc., such as the name of Taiwan, China. The new patent No. M352352 for [endoscope head swing device] discloses a kind of endoscope head swing device, which includes a head swing mechanism, an elastic component, a support part, a first line body, a second The two-wire body and the two-way flexible body can make the endoscope have the effect of turning by the combination of the above components. However, there are still some problems to be overcome in the use of this endoscope swing head device:

1、该弹性组件为弹簧，弹簧使用次数一多就容易造成弹性疲乏而断裂，进而影响摆头装置的运作，造成使用者极大的不便。1. The elastic component is a spring. If the spring is used too many times, it will easily cause elastic fatigue and break, which will affect the operation of the swinging head device and cause great inconvenience to the user.

2、内视镜摆头装置必须再配置一双向可挠体，不但生产程序更加繁琐，且成本亦大量增加。2. The swinging device of the endoscope must be equipped with a two-way flexible body, which not only makes the production process more cumbersome, but also greatly increases the cost.

3、内视镜摆头装置仅有两个方向的转向，造成使用上的不便。3. The head swing device of the endoscope can only turn in two directions, which causes inconvenience in use.
