Arthroscopic system with disposable arthroscope having image rotation function and method thereof

An arthroscopic system comprising:

• a disposable arthroscope having a distal end and a proximal end and comprising:
• a light source set up in said distal end for providing a light;
• a lens set set up in said distal end for gathering said light, wherein said lens set has a front end with a bevel angle;
• an image sensor directly coupled to said lens set for generating a digital raw data from said light;
• a control interface set up on a transmitter between said distal end and said proximal end, wherein said control interface is configured to generate a rotation angle control signal for controlling and indicating a rotation angle of said digital raw data, and said transmitter is a Serializer/Deserializer (SerDes) configured to transmit said digital raw data and said rotation angle control signal toward said proximal end;
• and
• a cable set up at said proximal end for transmitting said digital raw data and said rotation angle control signal;
• a processing system attached to said proximal end for capturing and converting said digital raw data into a digital video data, wherein said digital video data is digitally rotated according to said rotation angle control signal;
• and
• a video display device for displaying said digital video data.
