s1, when the device is used, firstly, the device is placed on an operating bed of a patient according to needs, then, the cut myoma wound is opened, two U-shaped movable plates (28) are pulled towards the left side respectively, the U-shaped movable plates (28) on the upper side and the lower side drive connecting plates (24) on the two sides to move towards the left side respectively, the connecting plates (24) drive a T-shaped sliding block II (23) to slide leftwards in a T-shaped sliding groove III (22), meanwhile, a spring I (19) is driven to stretch until a guide plate (26) is contacted with a bolt (29), a spring II (30) sleeved outside the bolt (29) is driven to stretch, after the guiding plate (26) passes through an inclined plane, the bolt (29) is inserted into a positioning hole (27) through the tensile force of the spring II (30), and the moved U-shaped movable plates (28) are fixed;

s2, meanwhile, each U-shaped movable plate (28) drives the hinged arc-shaped plates (31) to move leftwards, the arc-shaped plates (31) drive the fixedly connected slide bars (32) to slide leftwards in the slide bar grooves (33), and when the slide bars (32) slide to the leftmost side, the two arc-shaped plates (31) on the upper side are turned downwards and the two arc-shaped plates (31) on the lower side are turned upwards through the slide bar grooves (33) arranged in an arc shape, so that the four arc-shaped plates (31) are annular;

s3, adjusting the height of a U-shaped plate II (8) according to the height of the wound, controlling the electric push rod (6) to extend through the control switch (3), rotating the threaded rod I (4) after the U-shaped plate II (8) rises to a proper height, enabling the I-shaped slide block (5) in threaded connection on the threaded rod I (4) to move leftwards, so as to drive the U-shaped plate II (8) fixedly connected above to move leftwards, until the left ends of the two clamping plates (10) are inserted into the wound, controlling the motor (12) through the control switch (3) to drive the threaded rod II (11) to rotate, driving the threaded sleeve (13) in threaded connection to move through the threaded sleeve (11), driving the upper and lower side supporting rods (14) in fixed connection to move through the threaded sleeve (13), driving the hinged T-shaped slide block I (16) to slide in the T-shaped sliding groove II (17) through the two supporting rods (14), thereby the left end that drives two grip blocks (10) through lever principle is close to the centre gripping to the middle part, after the myoma is fixed in the centre gripping, cuts the myoma, and it is external to take out the myoma under the cutting through reverse rotation threaded rod (4) afterwards, accomplishes the operation.
