Abstract: An endoscope with a USB signal transmission includes an exploring tube, a lens, an image sensing element and a USB chip. The image sensing element has an output circuit for outputting a series signal. The USB chip is coupled to an image sensing element. The series-to-universal series unit converts the series signal into a universal series bus signal. The power supply circuit supplies electric power to the image sensing element. The data transmission circuit transmits a universal series bus signal. The USP chip integrates the output circuit into a power supply circuit and a data transmission circuit of a USB specification and converts the series signal into the universal series bus signal.

Abstract: The present invention discloses a two-way endoscope steering mechanism and four-way endoscope steering mechanism, and the two-way endoscope steering mechanism includes a hollow steering member, a two-way flexible plastic member and a guiding wire member. The hollow steering member has a hollow positioning portion and a connecting portion. The guiding wire member is passed and installed in the hollow positioning portion. The densely wound coil is coupled to an end of a steering module, and the steering module is formed by arranging and coupling the two-way flexible plastic member to the hollow steering member, and the densely wound coil is sheathed on the guiding wire member, such that the guiding wire member can be pulled to drive the steering module to turn in a direction.

Abstract: The present invention discloses a micro sensing apparatus comprising a sensing device, a cylindrical plastic body and a plurality of circuits. The sensing device has a bottom surface. The cylindrical plastic body is axially coupled to the sensing device and includes a connecting portion and a carrying portion, and the connecting portion has a first end surface coupled to the bottom surface, and the carrying portion is integrally formed and coupled to the connecting portion, and the carrying portion includes a plurality of electronic devices installed thereon and a plurality of circuits formed on the carrying portion. With the integrally formed connecting portion and carrying portion, the problem of requiring an adapting mechanism of a conventional sensing device to couple a printed circuit board can be solved. The cylindrical plastic body is axially coupled to the sensing device to reduce the overall external diameter of the micro sensing apparatus.
