Endoscope, a picture sensor, optical lens, light source lighting, mechanical devices, etc., can enter the stomach through the oral cavity or enter the body through other natural channels, so as to peep at the changes of relevant parts. It can help doctors to check the condition of the cavity more comprehensively, and carry out the operation under the visual condition, which greatly improves the safety of the operation. Endoscopes can be divided into three categories according to their development and imaging structure: rigid tube endoscope, optical fiber (hose type) endoscope and electronic endoscope. Many people can't distinguish the rigid tube endoscope from the flexible tube endoscope. What is the difference between the rigid tube endoscope and the flexible tube endoscope? Let's learn about the maintenance of endoscope equipment.

硬管式内窥镜和软管式内窥镜区别：

The difference between rigid tube endoscope and flexible tube endoscope is as follows

1、外观形态不同

1. The appearance is different

硬管式内窥镜：镜身主体不可弯曲或扭转， 硬管式内窥镜进入机体的深度和距离都远远低于软管式内窥镜；

Rigid tube endoscope: the body of the rigid tube endoscope can not be bent or twisted, and the depth and distance of the rigid tube endoscope entering the body are far lower than that of the hose endoscope;

软管式内窥镜：镜身柔软，可弯曲的一类腔镜。

Flexible tube endoscope: a kind of flexible endoscope with flexible body.

2、内部结构不同

2. The internal structure is different

硬管式内窥镜：按照结构形式可分为直杆不可分离硬管内镜、直杆可分离硬管内镜、弯管不可分离硬管内镜和弯管可分离硬管内镜四大类。各类硬管内镜结构一般包括外镜管（或鞘套）、镜体、光导束接口、目端接管以及成像接口部分。与软式内镜均有操作孔道不同，部分硬式内镜镜身无器械及水气孔道，如腹腔镜、胸腔镜、纵膈镜、关节镜等；各类操作器械需通过另辟切口来进入体腔内，在硬式内镜的监视和配合下完成手术操作。

Rigid tube endoscope: according to the structure, it can be divided into four categories: straight rod non separable rigid tube endoscope, straight rod separable rigid tube endoscope, elbow non separable rigid tube endoscope and elbow separable rigid tube endoscope. All kinds of hard tube endoscopy structures generally include the outer tube (or sheath), lens body, optical beam interface, eye nozzle and imaging interface. Different from soft endoscopy, some rigid endoscopes have no instruments and water vapor channels, such as laparoscopy, thoracoscopy, mediastinoscopy, arthroscopy, etc.; all kinds of operating instruments need to be cut through another incision to enter the body cavity, and the operation is completed under the supervision and cooperation of the hard endoscope.
             

软管式内窥镜：一般包括以下基本构造：前端部，弯曲部，插入管，操纵部，接目部以及成像接口部。其前端部是硬性部分，端面有多个腔道和窗面，分别为送水送气出口孔，活检钳出口孔，物镜以及导光窗。送水送气为共同出口，注气时，气体由此孔进入人体腔内使腔体扩张；注水时，水从此孔出来冲洗物镜镜面及手术野，使视野保持清晰。负压吸引及活检钳出口孔为同一管口，当腔内有过多液体妨碍观察时，按压吸引按钮，液体可由此孔吸入吸引瓶内；活检钳和其他器械也从此孔进入体腔内。弯曲部位于前端和插入管之间，由许多环状零件组成蛇管，每对相邻的环状零件之间均可作各个方向的活动。插入管又叫镜身或软管部，内部为各类管道和钢丝。操纵部包括角度控制旋钮，吸引阀按钮，送水送气按钮以及活检管开口，术者可以在此操作各种按钮已完成内镜检查和。

Flexible tube endoscope: it generally includes the following basic structures: front end part, bending part, insertion tube, operation part, eye connection part and imaging interface part. The front end is a hard part, and the end face has many cavities and windows, which are the water supply and air supply outlet hole, the biopsy forceps outlet hole, the objective lens and the light guide window. Water and gas supply is the common outlet. During gas injection, gas enters the human cavity through this hole to expand the cavity; when water is injected, water comes out from this hole to wash the mirror surface of objective lens and surgical field, so as to keep the visual field clear. From this point on, the suction of liquid from the same orifice of the forceps and other cavities can be obstructed by pressing the suction button in the same cavity, and the aspiration of liquid can also be obstructed by pressing the suction button in the same cavity. The bending part is located between the front end and the insertion tube, which is composed of many annular parts. Each pair of adjacent annular parts can move in various directions. The insertion tube is also called mirror body or hose part, with various pipes and steel wires inside. The control part includes angle control knob, suction valve button, water and air supply button and biopsy tube opening. The operator can operate various buttons here to complete endoscopic examination and treatment.
