[0002] An endoscope is an electronic instrument commonly used in medical examinations and industrial flaw detection. An endoscope includes an insertion portion that extends into the human body or the interior of a device and an endoscope handle that controls the movement of the insertion portion, video recording, and lighting. The insertion portion includes an insertion tube, a controllable bending portion, and a tip. The tip is equipped with a camera, an instrument channel, and a light source. The endoscope handle includes a housing, an angle pull rope for controlling the steering of the tip, and multiple functional components. The multiple functional components are used to fix the routing path of the angle pull rope, the access channel of the surgical instrument, the connection of the circuit board and various signal lines, etc. When assembling a traditional endoscope handle, multiple functional components need to be installed in the housing and the angle pull rope is installed. Since there are many parts and complex structures in the endoscope handle, the assembly process requires the use of cumbersome production processes to complete the assembly. Therefore, the assembly personnel are required to have a high level of proficiency. The use of this assembly method will result in a long production assembly time and low efficiency, which will directly affect the production benefits. When the product is put on the market, it is not conducive to the maintenance and maintenance of the endoscope handle by later users. Summary of the invention

[0003] The first object of the present invention is to provide an internal skeleton component that is easy and quick to assemble, which can not only improve the assembly efficiency but also facilitate the user's subsequent maintenance and care.

[0004] A second object of the present invention is to provide an endoscope handle comprising the above-mentioned internal skeleton assembly.

[0005] A third object of the present invention is to provide an endoscope comprising the above-mentioned internal skeleton assembly.

[0006] In order to achieve the above-mentioned first purpose, the present invention provides an internal skeleton component, including an angle adjustment mechanism, a first mounting seat, a second mounting seat, a wiring seat, a first connecting seat, a second connecting seat, a surgical instrument channel mechanism and a third connecting seat, wherein the angle adjustment mechanism is arranged on the first end of the first mounting seat; the first mounting seat, the second mounting seat and the wiring seat are arranged in an X-direction, an insertion tube and a first signal line connecting mechanism are arranged on the wiring seat, the insertion tube extends along the X-direction, a signal line mounting hole is arranged in the first signal line connecting mechanism, and the signal line mounting hole is connected to the insertion tube; the first end of the first connecting seat is respectively connected to the second end of the first mounting seat and the first end of the second mounting seat; the second connecting seat is located between the second mounting seat and the first connecting seat, the first side of the second connecting seat is respectively connected to the second end of the second mounting seat and an end of the wiring seat away from the insertion tube, and the second side of the second connecting seat is connected to the first connecting seat; the surgical instrument channel mechanism is obliquely arranged on the wiring seat along the X-direction, the surgical instrument channel mechanism is provided with a first instrument channel, and the first instrument channel is connected to the insertion tube; the third connecting seat is respectively connected to the second end of the first connecting seat and the surgical instrument channel mechanism.

[0007] It can be seen from the above scheme that the internal skeleton component of the endoscope handle is formed by assembling and connecting the functional components such as the angle adjustment mechanism, the first mounting seat, the second mounting seat, the wiring seat, the first connecting seat, the second connecting seat, the surgical instrument channel mechanism and the third connecting seat, so that the internal skeleton component is combined into a whole, which can be subsequently installed in the handle housing, which is conducive to facilitating the connection and installation between various functional components. During the installation process, there is no need to use cumbersome and complicated production processes, which is conducive to reducing the requirements for the proficiency of the assembly personnel, saving assembly time and improving assembly efficiency. Later, the user only needs to remove the internal skeleton component from the endoscope housing to maintain and service the internal skeleton component of the endoscope handle, which is simple and convenient to operate.

[0008] A further solution is that the angle adjustment mechanism includes a rotating disk, an angle rope, an upper cover, a handle, an active rotating shaft, a driven rotating shaft, a driving gear, a driven gear and two angle rope brake protection tubes, a first end of the first mounting seat is provided with a first mounting groove, the upper cover is provided on the first mounting groove, the rotating disk is rotatably provided in the first mounting groove, and the active gear and the driven gear are both located between the upper cover and the first mounting seat; the two ends of the active rotating shaft are respectively connected to the handle and the first mounting seat, and the middle part of the active rotating shaft passes through the upper cover and the active gear; the two ends of the driven rotating shaft are respectively connected to the upper cover and the first mounting seat, the middle part of the driven rotating shaft passes through the driven gear and the rotating disk, and the driven gear is connected to the active gear; the middle part of the angle rope is wound around the rotating disk, and the two ends of the angle rope respectively pass through the corresponding angle rope brake protection tubes and extend along the X direction to the insertion tube; the upper cover is provided with an arc-shaped groove, the active gear is provided with a stop block, the stop block is embedded in the arc-shaped groove, and the stop block can rotate around the active rotating shaft in the arc-shaped groove.

[0017] A further solution is that the wiring seat is also provided with an instrument channel mounting part, a signal line mounting part, a guide plate and an insertion tube mounting part.
