In recent years, endoscopes and surgical instruments thereof are widely used in the field of minimally invasive diagnosis and treatment, and with the rapid development of minimally invasive medical technology, higher requirements are put on the endoscopes. The classification is carried out according to different positions reached by the endoscope: it is divided into neuroscope, urethrocystoscope, resectoscope, laparoscope, arthroscope 10, nasosinusitis, laryngoscope, etc. According to the bending of the endoscope head, the endoscope can be divided into a soft endoscope and a hard endoscope. The endoscope structure may be reusable.

Medical products, particularly related products in contact with blood and mucosal tissue, are very demanding for single use; at home and abroad, a plurality of designs of sheathing a layer of skin or a sheath on a repeated endoscope exist. This similar design has several problems: 1. the outer diameter of the endoscope will be increased; 2. the disassembly and the assembly are complex, and the risk of sterile cross contamination exists; 3. the sheath cannot be completely isolated from the handle in a sterile manner only at the insertion portion. 4. The use operation can be seriously influenced by sheathing the skin on the whole endoscope; 5. the illumination and reflection of the skin can interfere with the imaging. 6. The skin may affect the endoscope bend angle, etc.

In one embodiment, in the production and manufacturing process of the disposable endoscope body structure, the flexible insertion part 11, the length of the image pickup channel thereof, and the like are difficult to control accurately; meanwhile, in the disposable endoscope structure, the flexible insertion portion 11 and the imaging channel therein may be elongated or compressed under different conditions during the bending process.

Therefore, based on the above two situations, the camera packaging part 23 may have difficulty reaching a predetermined position, for example, the end of the flexible insertion part 11 cannot be reached accurately to capture an image in front, and further, the field angle of the image is directly affected or reduced, and the field range is reduced. Therefore, the present embodiment further introduces an elasticity compensation structure 212, and specifically, the handle 21 includes a holding head 211 and the elasticity compensation structure 212 disposed on the holding head 211.

Through above scheme, based on the elasticity compensation structure, usable elastic force guarantees that camera encapsulation portion can be in required position, eliminates the influence that the dimensional error of making and assembling brought to making a video recording.

In the specific implementation process, the male head 22 and the elastic component through hole are arranged on the same side wall of the holding head, and then, the holding head can be accessed and the male head and the female seat can be butted at the same time through the access movement in the same direction.
