Problems solved by technology

However, since the lumens in the human body, such as the large intestine and small intestine, are very curved, the large intestine or small intestine will be straightened after the tube is inserted, which will bring painful experience to the patient

Embodiment Construction

[0038] The following description provides many different embodiments, or examples, for implementing various features of the invention. The components and arrangements described in the following specific examples are only used to express the present invention in a concise manner, which are only examples and not intended to limit the present invention.

[0039] Endoscope is a commonly used medical device, an inspection device that can directly enter the natural pipeline of the human body, and can provide doctors with sufficient diagnostic information to treat diseases. When in use, the insertion part of the endoscope enters the human body through the natural orifice of the human body or through a small incision made by surgery, and the doctor can directly observe the changes of the relevant parts.

[0040] The insertion portion of an endoscope generally includes a snake section, a passive bending section, and an insertion tube section. Among them, the snake bone section is form...

Abstract

The invention is suitable for the technical field of endoscopes, and provides an insertion part, an endoscope and a driving method. The insertion part comprises an insertion tube, and a first deformation body, a first driving body, a second driving body and a second deformation body which are sequentially arranged in the axial direction of the insertion tube; the first deformation body and the second deformation body can be deformed to be in contact with the inner wall of the insertion object of the insertion tube; the first deformation body can slide in the axial direction of the insertion tube, the first driving body is fixedly connected with the first deformation body, the second deformation body is fixedly connected with the insertion tube, and the relative position between the second driving body and the second deformation body is fixed; and acting force for enabling the first driving body and the second driving body to be close to or far away from each other can be generated between the first driving body and the second driving body. According to the invention, the forward movement of the insertion part in the insertion object is realized through the driving structure at the foremost end.

Description

technical field [0001] The present invention relates to an endoscope, in particular to an insertion part, an endoscope and a driving method. Background technique [0002] Endoscope is a commonly used medical device, an inspection device that can directly enter the natural pipeline of the human body, and can provide doctors with sufficient diagnostic information to treat diseases. When in use, the insertion part of the endoscope enters the human body through the natural orifice of the human body or through a small incision made by surgery, and the doctor can directly observe the changes of the relevant parts. [0003] The insertion portion of an endoscope generally includes a snake section, a passive bending section, and an insertion tube section. Among them, the snake bone segment is the softest, and the insertion tube segment is the hardest. Existing endoscopes go deep into the inner wall of the insertion object generally by applying force to the harder insertion tube end...
