Endoscope with movable front end

Abstract

The invention relates to the technical field of endoscopes, and discloses an endoscope with a movable front end, which comprises a main tube, at least one elastic deformation part, a driving unit and a camera part, the main pipe comprises a bending part and a main pipe cavity, the bending part is used for bending the front end of the main pipe, and a working appliance is inserted into the main pipe cavity; the elastic deformation part can shield an outlet of the main pipe cavity; the driving unit is used for applying acting force to the elastic deformation part, so that the elastic deformation part is elastically deformed to generate radial movement along the main pipe shaft, and the elastic deformation part is moved away from or back to an outlet of the main pipe cavity; the imaging part is used for observing a detected body; and the camera part is arranged on the elastic deformation part or is independent of the elastic deformation part and is rigidly connected with the main pipe. According to the endoscope with the movable front end, under the condition that the insertion performance and operability of the endoscope in a human body lumen are not affected, the size of a working channel can be increased, an image sensor with a large size can be used, and the efficiency that a doctor uses the endoscope for treatment is improved.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to an endoscope with a movable front end. Background technique [0002] Endoscope is a commonly used medical device that integrates traditional optics, precision machinery, and electronic circuits. It can enter the stomach through the mouth or enter the body through other natural orifices, and is used to treat tissues and organs inside the human body, such as stomach , esophagus, duodenum, colorectum and other parts of the lesions can be observed by using the endoscope to see the lesions that cannot be displayed by other medical equipment such as CT, ultrasound and magnetic resonance imaging, so as to assist the doctor to make a more accurate diagnosis of the patient's condition diagnosis. [0003] At present, the end of the endoscope lens includes non-working channel functional devices such as a camera, lighting window, and flushing nozzle, which occupy a large space. When the ...
