[0032] A further optimized solution is that a plurality of stator winding slots 601 are circumferentially opened on the side wall of the stator block 6, and the stator winding is installed in the stator winding slots 601. A plurality of permanent magnet mounting slots 501 are opened on the inner side of the detection rotating head 5, and the number of the permanent magnet mounting slots 501 matches the number of the stator windings. The stator winding is electrically connected to the control circuit board, and a conductive part is provided between the stator block 6 and the detection rotating head 5.

[0033] A further optimized solution is that the conductive parts include a plurality of conductive rings 602, which are embedded in the end surface of the stator block 6 and located on a side close to the detection rotating head 5.

[0036] To further optimize the solution, a detector threading hole 603 is provided at the center of the stator block 6, a wiring hole 301 is provided at the center of the flexible support rod 3, and a through hole 201 is provided at the center of the support rod 2. The wiring hole 301, the through hole 201, and the detector threading hole 603 are coaxially arranged.

[0037] The working principle of this embodiment is as follows:

[0038] The upper computer is responsible for receiving the signal transmitted by the control circuit board. Several conductive rings are provided on the outer side of the support rod 2. Several elastic electrodes are provided on the inner wall of the guide tube 102. The elastic electrodes are in contact with the corresponding conductive rings. The power supply of the LED lamp beads, camera, ultrasonic probe, stator winding slot 601, first electromagnetic coil and second electromagnetic coil can be transmitted through the elastic electrodes and conductive rings to transmit electrical energy and signals. The mobile handle 101 is responsible for controlling the operating position of other components. When the arthroscope needs to be bent, the operation is performed through the corresponding buttons set on the handle 1. At this time, the control circuit board receives the corresponding signal and controls the corresponding second electromagnetic coils on the adjacent drive blocks 4 to be energized. At this time, the corresponding sides of the two adjacent drive blocks 4 will be attracted to each other under the influence of the magnetic field. Since the flexible support rod 3 adopts a flexible design, the two second electromagnetic coils will attract each other at this time. By controlling the second electromagnetic coils on different drive blocks 4 to be energized, mutual attraction or repulsion can be achieved. In this way, the extension and retraction of the electronic arthroscope can be realized. The camera transmits the captured image to the control circuit board. The information is transmitted to the host computer via the control circuit board, and then used for image display on the display after information processing by the host computer. The ultrasonic probe is used to detect the position of blood vessels and nerves in the joint, and the signal is transmitted to the host computer via the control circuit board, and then used for display of the position of blood vessels and nerves by the host computer after information processing; the stator winding on the stator block 6 cooperates with the permanent magnet on the detection rotating head 5. When it is necessary to rotate the detection rotating head 5 to control the rotation of the ultrasonic probe position, by pressing the corresponding moving handle 101, the control circuit board controls the stator winding to be energized, and then the permanent magnet rotates under the magnetic force of the stator winding. In this way, the ultrasonic probe can be rotated 360 degrees, and detection in different directions can be achieved without rotating the arthroscope, which brings great convenience to the implementation of the operation. The structural settings of the detection rotating head 5 and the stator block 6 can be coordinated to achieve structural simplification, so that the volume of the front detection end of the electronic mirror becomes smaller, so that a flexible protective cover can be set on the outside of the multiple drive blocks 4 according to the outer dimensions, thereby ensuring the realization of the overall function of the arthroscope.
