[0002] Endoscope is the tubular medical instrument with optical lens and mechanical device, which enters the body through natural orifice or small incision, and can observe the disease tissue. The original endoscope pipeline is made of hard tube, although they are gradually improved, but due to the limitation of human structure, the hard endoscope cannot meet all clinical needs. Later, in the 1950s, the endoscope is made of soft tube, so it can easily bend at the corner of the human body. The current endoscope usually has two different working principles, one is two glass fiber tubes, light enters the body through one of them, and the doctor observes through the other tube or through a camera, and the other endoscope is a miniature integrated circuit sensor, which feeds back the observed information to the computer.

[0003] At present, the size of the first end part of the soft tube endoscope is limited by the volume of the parts and the technical level of the assembly personnel, and the unbendable part of the produced first end part is generally more than 10mm. In the process of clinical use, the soft tube endoscope with long unbendable part of the first end part will have the following disadvantages when entering the human body from the narrow cavity: the lung bronchus examination will enter the bronchus from the nasal cavity, and the nasal cavity diameter of about 3-4mm will cause serious discomfort and pain to the patient, and too much pain will make the patient unable to cooperate with the doctor to complete the operation, and local anesthesia may be needed to make the doctor complete the examination smoothly.

[0025] Reference Figures 1 to 2 The present application describes an endoscope with a short non-bendable part of the tip.

[0026] As Figures 1 to 2As shown, the end head unbendable part short endoscope according to the embodiment of the utility model includes: lens module 100, lens module 100 includes lens part 110, filter PCB 120 and bottom end part 130, lens part 110, filter PCB 120 and bottom end part 130 are sequentially arranged from top to bottom, end head 200, end head 200 is wrapped in the outside of lens part 110, snake bone piece 300, snake bone piece 300 is wrapped in the outside of bottom end part 130, filling part 400, filling part 400 is wrapped in the outside of filter PCB 120, the outer contour of filling part 400 is cylindrical, and filling part 400 is used for bundling fishing line.

[0027] In the existing endoscope structure, the whole end head structure is relatively long, the end head will wrap the whole lens and PCB board, and the area for bundling fishing line is independently arranged below the end head.In the present application, the end head 200 only wraps the lens part 110, and the filter PCB 120 is exposed outside the end head 200. The outside of the filter PCB 120 is filled by the filling part 400 to form a cylindrical outer contour, which facilitates the bundling of fishing line and replaces the original area for bundling fishing line, thereby reducing the height of the unbendable part of the end head 200. In the use scenario of the respiratory department, the channel of the nasal cavity is relatively narrow, and if the unbendable part of the end head 200 is relatively long when it enters the trachea from the nasal cavity, it will cause discomfort to the patient. The improvement of the end head unbendable part short endoscope can reduce the length of the unbendable part and improve the user experience of the patient.

[0028] As shown in Figure 1 and Figure 2 , the end head 200 is in the form of a hollow cylinder, and the installation slot 210 is arranged in the end head 200. The installation slot 210 is arranged along the axis of the end head 200, and the shape of the installation slot 210 is consistent with the shape of the lens part 110. The lens part 110 is arranged in the installation slot 210. The end head 200 is provided with a plug-in part 220 at the lower end, and the end head 200 is connected with the snake bone piece 300 through the plug-in part 220. The plug-in part 220 is provided with two, and the two plug-in parts 220 are in the form of circular arc pieces. The two plug-in parts 220 are respectively arranged on both sides of the filter PCB 120. The two plug-in parts 220 in the form of circular arc pieces are symmetrically arranged along the axis of the end head 200. The outer diameter of the plug-in part 220 is consistent with the inner diameter of the snake bone piece 300, and the two plug-in parts 220 are arranged in the snake bone piece 300. In the existing endoscope structure, the lens and the PCB need to be accommodated in the end head, so the end head needs to be processed with a stepped hole. In the end head unbendable part short endoscope, the end head 200 only needs to accommodate the lens part 110, so the installation slot 210 only needs to be processed into a through hole, which reduces the processing difficulty of the end head 200 and saves costs.

[0029] As shown in Figure 1 and Figure 2As shown, it further comprises a curved rubber 500 wrapped outside the snake bone piece 300 and the filter PCB 120. The outer diameter of the curved rubber 500 is consistent with the outer diameter of the tip head 200, and the upper end of the curved rubber 500 abuts the lower end of the tip head 200. The filter PCB 120 is cuboid-shaped, and the outer side of the filter PCB 120 is coated with glue to form a filling part 400 with a cylindrical outer contour.

[0030] The embodiments of the utility model are explained in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge range possessed by the ordinary skilled in the art without departing from the purpose of the utility model.
