[0002] An endoscope is a medical device that a doctor can insert into a natural orifice or small incision in the body to examine organs and tissues inside the body. There are many types of endoscopes, including laparoscopes, thoracoscopes, arthroscopy, and cystoscopes. It is commonly used to diagnose and treat a variety of diseases, such as gastrointestinal diseases, lung diseases, and joint diseases. An endoscope consists of a long, thin tube, a camera, and a light source that transmits images to a monitor for the doctor to view.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0019] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0020] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides an endoscope MIPI fixing plate safety locking mechanism, including a positioning sleeve 3, an endoscope catheter 1 is inserted into the interior of the positioning sleeve 3, a U-shaped shell connected to the positioning sleeve 3 is installed on the upper end of the positioning sleeve 3, a sleeve 2 is installed on a section of the endoscope catheter 1 away from the lens, a plurality of annular structure grooves 12 are axially arranged on the outer ring surface of the sleeve 2, a gear 7 is arranged inside the U-shaped shell, the convex teeth of the gear 7 are inserted into the corresponding grooves 12, a positioning assembly for positioning the gear 7 is installed on the top surface of the U-shaped shell, a telescopic rod 9 is installed on the bottom surface of the positioning sleeve 3, and a clamp 11 is installed on the lower end of the telescopic rod 9.

[0022] In this embodiment, the positioning assembly includes a positioning plate 6 and multiple side plates 5. A positioning hole 16 is provided on the top surface of the U-shaped shell. The lower end of the positioning plate 6 extends into the U-shaped shell through the positioning hole 16. A plurality of plug-in portions 15 matching the tooth grooves on the gear 7 are protruded from the bottom surface of the positioning plate 6. The plug-in portions 15 are all inserted into the corresponding tooth grooves. A through hole for inserting fingers is provided on one end of the positioning plate 6 located on the outside. The side plates 5 are arranged on both sides of the positioning plate 6, and the lower ends of the side plates 5 are all installed on the top surface of the U-shaped shell.

[0023] In this embodiment, a slide groove is vertically provided on the inner side surface of the side plate 5, and a slider 18 is slidably installed in the slide groove. One side of the slider 18 is installed on the positioning plate 6. The cross-section of the slider 18 and the slide groove is arranged in a trapezoidal structure. A compression spring 17 is installed on the top surface of the slider 18, and the other end of the compression spring 17 is installed on the top surface of the slide groove.

[0024] In this embodiment, mounting holes are provided on both side surfaces of the U-shaped shell, and sealed bearings 14 are installed in the mounting holes. A shaft rod 13 is installed at the center of the gear 7, and both ends of the shaft rod 13 are installed in the inner ring of the sealed bearing 14. One end of the shaft rod 13 extends outward and is equipped with a handwheel 8. The handwheel can be used to rotate the sleeve in a small range, so that the endoscope catheter can move a small distance to control the accuracy of the movement.

[0025] In this embodiment, the sleeve 2 is made of rubber material, and a plurality of metal rings of annular structure are installed inside the sleeve 2. The metal rings increase the firmness of the sleeve all day long and can be better positioned by the gears, but will not affect the bending of the sleeve.

[0026] In this embodiment, the length and width of the positioning opening 16 match the length and width of the cross section of the positioning plate 6, so that the positioning plate can only move vertically up and down along the positioning opening, avoiding rotation or deviation of the positioning plate and increasing stability during movement.

[0027] When in use, the endoscope catheter can be directly inserted into the positioning sleeve, and the finger is inserted into the through hole, and the positioning plate is lifted upward. After the insert on the positioning plate is disengaged from the tooth groove of the gear, the endoscope catheter can be quickly pulled axially along the positioning sleeve, and the gear can be driven to rotate independently. When making precise adjustments, the hand wheel can be directly held and rotated. The rotation of the hand wheel drives the shaft rod, and the rotation of the shaft rod drives the gear. The sleeve and the endoscope catheter can be moved by the rotating gear, so that the endoscope catheter can move forward or backward in a precise state, which increases the control of the distance of the endoscope catheter.

[0028] After the position of the endoscope catheter is determined, the positioning plate can be released. At this time, the slider can be pushed downward by the rebound of the compression spring. The movement of the slider drives the positioning plate, so that the insert at the lower end of the positioning plate can be inserted into the tooth groove of the gear, thereby positioning the gear, sleeve and endoscope catheter. It can be seen from the above operation that there is no need to use clamping to position the endoscope catheter, which avoids the endoscope catheter being clamped and increases safety and efficiency.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
