The holding unit connects to the capture unit through a coaxial cable, and comprises a disposable image-capture module, a synthetic-image module (L/R montage), a Mipi serializer, a Mipi deserializer, a Mipi capture card, and a capture device. Thus, the apparatus keeps the most expensive ISP and capture device at a back end; and puts the disposable image-capture module, the synthetic-image module, and the Mipi serializer at a front end. After use, it is only necessary to discard the disposable image-capture module, which extends into human body at the front end. The remaining parts are reused. Thus, cost is effectively reduced and the shortcoming of high cost of the use of modern disposable endoscope is solved.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present invention will be better understood from the following detailed description of the preferred embodiment according to the present invention, taken in conjunction with the accompanying drawings, in which

[0008] FIG.1 is the view showing the structure of the preferred embodiment according to the present invention; and

[0009] FIG.2 is the view showing the detail of the structure.

DESCRIPTION OF THE PREFERRED EMBODIMENT

[0010] The following description of the preferred embodiment is provided to understand the features and the structures of the present invention.

[0011] Please refer to FIG.1 and FIG.2, which are a view showing the structure of a preferred embodiment according to the present invention; and a view showing the detail of the structure. As shown in the figures, the present invention is an apparatus of medical endoscope using Mipi serializer/deserializer 100, comprising a holding unit 10 and a capture unit 20. The holding unit 10 and the capture unit 20 are connected through a coaxial cable 30, and comprise a disposable image-capture module 11, a synthetic-image module 12, a Mipi serializer 13, a Mipi deserializer 21, a Mipi capture card 22, and a capture device 23.

[0012] The disposable image-capture module 11 is set at a front end of the holding unit, and comprises a left image sensor 111 and a right image sensor 112. Therein, the front end of the holding unit 10 is a guide tube, which can extend into a body and has a length of at least 30 centimeters.

[0013] The synthetic-image module 12 is set in the holding unit 10 and connects to the disposable image-capture module 11.

[0014] The Mipi serializer 13 is set in the holding unit 10 and connects to the synthetic-image module 12.

[0015] The Mipi deserializer 21 is set in the capture unit 20 and connects to the Mipi serializer 13 through the coaxial cable 30, where the coaxial cable 30 has a length of 2-10 meters.

[0016] The Mipi capture card 22 is set in the capture unit 20 and connects to the Mipi deserializer 21.

[0017] The capture device 23 is set in the capture unit 20 and connects to the Mipi serializer 22.

[0018] The apparatus of medical endoscope using Mipi serializer/deserializer 100 further comprises a power-over-cable (PoC) module 40, where the PoC module 40 comprises a PoC sending circuit 41 set between the coaxial cable 30 and the Mipi deserializer 21; and a PoC receiving circuit 42 set between the Mipi serializer 13 and the coaxial cable 30. Thus, a novel apparatus of medical endoscope using Mipi serializer/deserializer 100 is obtained.

[0019] On using the present invention, the disposable image-capture module 11 at the front end of the holding unit 10 extends into the body to use the left image sensor 111 to capture a set of left-image signals and the right image sensor 112 to capture a set of right-image signals. The set of left-image signals (L signals) and the set of right-image signals (R signals) are converted to be conformed to a Mipi single-channel (Mipi-1-lane) interface.

[0020] The synthetic-image module 12 receives the L signals and the R signals to form a set of synthesized image signals (L+R signals) containing all of the L signals and the R signals. After the set of synthesized image signals are converted to be conformed to a Mipi dual-channel (Mipi-2-lane) interface, the Mipi serializer 13 Mipi-serializes the set of synthesized image signals to output a flow of Mipi-serialized image data to the coaxial cable 30.

[0021] In addition to data transmission, the apparatus of medical endoscope using Mipi serializer/deserializer 100 also uses a coaxial-cable power supplier 40 to supply power in a reverse direction. As shown in FIG.1, the PoC sending circuit 41 is configured to send power over the coaxial cable 30; and the PoC receiving circuit 42 is configured to receive power from the coaxial cable 30 for supplying power to the disposable image-capture module 11 at the front end of the holding unit 10.

[0022] The Mipi deserializer 21 receives the flow of Mipi-serialized image data through the coaxial cable 30 to Mipi-deserialize the flow of Mipi-serialized image data to be restored and conformed to the Mipi-2-lane interface for outputting the set of synthesized image signals to the Mipi capture card 22. In a state-of-use as shown in FIG.2, the Mipi capture card 22 has an L/R splitter 221, where the set of synthesized image signals is received to be split into two sets of image signals conformed to the Mipi-1-lane interface. Then, the two sets of image signals conformed to the Mipi-1-lane interface are outputted to an image signal processor (ISP) to be converted into two sets of image signals conformed to the Mipi-2-lane interface. The two sets of image signals conformed to the Mipi-2-lane interface are processed through a Mipi-to-parallel data conversion to obtain parallel signals compatible to the capture device 23. At last, the capture device 23 converts the parallel signals into video-format data.

[0023] Hence, the apparatus keeps the most expensive ISP and capture device at the back end; and puts the disposable image-capture module, the synthetic-image module, and the Mipi serializer at the front end. After use, it is only necessary to discard the disposable image-capture module whose front end extends into human body. The remaining parts are reused. Thus, cost is effectively reduced to solve the shortcoming of high cost of the use of modern disposable endoscope.

[0024] To sum up, the present invention is an apparatus of medical endoscope using Mipi serializer/deserializer, where the most expensive ISP and capture device are kept at a back endand a disposable image-capture module, a synthetic-image module, and a Mipi serializer are put at a front end; after use, it is only necessary to discard the disposable image-capture module, which extends into human body at the front end, but the remaining parts are reused; and cost is thus effectively reduced to solve the shortcoming of high cost of the use of modern disposable endoscope.

[0025] The preferred embodiment herein disclosed is not intended to unnecessarily limit the scope of the invention. Therefore, simple modifications or variations belonging to the equivalent of the scope of the claims and the instructions disclosed herein for a patent are all within the scope of the present invention.
