when the sliding groove (19) is close to the outermost end of the end cover (6) and is in contact with the rotation limiting strip (18), the sliding cover plate (3) is positioned above the semi-column section (15), the sliding cover plate (3) is positioned at the rear end of the sampling spoon (2), and the spoon opening (4) of the sampling spoon (2) is leaked out;
when the innermost end of the chute (19) far away from the end cover (6) is contacted with the rotation limiting strip (18), the sliding cover plate (3) is positioned right above the spoon opening (4) of the sampling spoon (2), and the cutting and sampling of the tumor body are completed.
7. The device for sampling the anatomical nodule of the infrapatellar synovial fold of claim 6, wherein: a connecting lead of the electrocoagulation blade (8) is embedded in an insulated sliding cover plate (3), a threading convex strip (20) is arranged at the top of the sliding cover plate (3), and a data wire of the arthroscope is accessed through a wire hole in the threading convex strip (20);
a wire placing slot hole (21) is formed in the push column, and a connecting lead of the electrocoagulation blade (8) and a data wire of the arthroscope are connected to the inner cavity of the hand piece (1) through the wire placing slot hole (21);
a threading round hole (22) is formed in the tail end of a push column in the inner cavity of the hand piece (1), and a connecting lead of the electrocoagulation blade (8) and a data line of the arthroscope are connected to the inner cavity of the hand piece (1) through the thread-placing long hole (21) and come out of the threading round hole (22).
8. The device for sampling the anatomical nodule of the infrapatellar synovial fold of claim 7, wherein: an adapter socket (23) is arranged in the inner cavity of the hand piece (1), and a connecting lead of the electrocoagulation blade (8) and a data line of the arthroscope are connected with the adapter socket (23) through a spiral telescopic lead (24);
an electrocoagulation knife electrifying switch (25) is arranged below the adapter socket (23) and controls the electrification of the electrocoagulation knife blade (8).
9. The device for sampling the anatomical nodule of the infrapatellar synovial fold of claim 8, wherein: the driving device is a micro lead screw motor (26), and a screw nut (27) is in transmission connection with the micro lead screw motor (26);
one end of the push column, which is positioned in the inner cavity of the hand piece (1), is detachably connected with a connecting seat (28), and the connecting seat (28) is connected with a screw nut (27) through a long rod (29); the rotation of the screw rod on the micro screw rod motor (26) drives the screw nut (27) and the push column to move, thereby driving the sliding cover plate (3).
10. The device for sampling the anatomical nodule of the infrapatellar synovial fold of claim 9, wherein: a motor switch (30) is arranged above the hand piece (1), and the motor switch (30) controls the micro screw rod motor (26).
