step 2.2, rotating the torsion gear lever 31b;
step 2.3, the anterior clamp contraceptive ring a:
the rotation stopping side hole 31c acts on the rotation stopping plug 21f to drive the rotary cylinder 21c, the limiting concave ring 21d and the front and rear groups of adjustable lock cylinders 21e to rotate;
the front adjustable lock cylinder 21e drives the front circular ring 23a and the plane threaded disc 23b to rotate, and the rear adjustable lock cylinder 21e idles and cannot effectively drive the side clamping device 22 to rotate;
the plane thread disc 23b drives the thread sliding block 23e and the front clamping arm 23f to move close to each other along the radial sliding groove 23d, so that the rod-shaped end part of the contraceptive ring a is clamped;
when the contraceptive ring a has no rod-shaped end portion, the step 2 comprises the following steps:
step 2.1, the side gripper device 22 is started:
rotating the ring gear 33e;
the ring gear 33e drives the planet gears 33b to rotate around the corresponding planet wheel carriers 33 a;
the planet gear 33b drives the central gear 33d and the internal threaded pipe 33c to rotate;
the internal threaded pipe 33c drives the external threaded pipe 32a, the driving convex ring 32b and the driven plug 32d to slide backwards along the stop rod side hole 32 c;
the driving convex ring 32b acts on the gear lever concave ring 31e, and then drives the torsion gear lever 31b and the expanding convex ring 31d to move to the rear end, and the expanding convex ring 31d triggers a group of adjustable lock cylinders 21e located behind:
the expanded convex ring 31d is abutted against the locking inserted rod 21e-3 and the spring retainer ring 21e-4 to enable the locking inserted rod to overcome the damping of the reset pressure spring 21e-5 and extend outwards along the radial direction, the locking inserted rod 21e-3 is abutted against the inner wall of the rear circular ring 22a to achieve locking matching, and the side clamping device 22 is started;
step 2.2, rotating the torsion gear lever 31b;
step 2.3, side clamping contraceptive ring a:
the rotation stopping side hole 31c acts on the rotation stopping plug 21f to drive the rotary cylinder 21c, the limiting concave ring 21d and the front and rear groups of adjustable lock cylinders 21e to rotate;
however, only the rear adjustable lock cylinder 21e drives the rear ring 22a and the side clamping plate 22c to rotate, and the front adjustable lock cylinder 21e idles and cannot effectively drive the front clamping device 23 to rotate;
the lateral splint 22c and the arc-shaped lateral opening 22b clamp the laterally positioned contraceptive ring a.
As a further embodiment:
the step 2.2 of rotating the rotation lever 31b specifically includes the steps of:
step 2.2.1, fast primary clamping:
the back end 42h, the switching core rod 42e and the transmission key block 42f are pushed forwards by fingers to overcome the elasticity of the switching pressure spring 42g so as to move forwards;
the transmission key block 42f is out of contact with the driven worm wheel 42 a;
the finger directly rotates the twist lever 31b.
As a further embodiment:
the step 2.2 further comprises:
step 2.2.2, accurate stable clamping:
the hands of the front push torsion rear end 42h, the switching core rod 42e and the transmission key block 42f are released, the switching pressure spring 42g drives the transmission key block 42f, the switching core rod 42e and the torsion rear end 42h to move backwards, and the transmission key block 42f is in transmission contact with the driven worm gear 42 a;
the driving worm 42b is rotated to expose the part outside the rod-shaped base 1, and the driving worm 42b drives the driven worm wheel 42a to rotate, so as to drive the transmission key block 42f and the torsion gear lever 31b to rotate.
It should be noted that the two methods for clamping the contraceptive ring are superior and inferior, and need to be used as appropriate:
the front clamping device clamps through radial movement of the front clamping arms, and the radial size of the rod-shaped base is limited, so that the radial movable range of the front clamping arms is limited, and the front clamping device is suitable for the intrauterine device with a rod-shaped end; but also because the radial moving range of the front clamping arm is limited, the endometrium of the patient is not easy to be injured by mistake in the mode.
The side clamping device clamps through a side clamping plate and an arc-shaped side opening, and the arc-shaped side opening is provided with a larger opening and can adapt to an intrauterine device without a rod-shaped end part, such as a uterus type; but also because the arc-shaped side opening is larger, the possibility of mistakenly clamping the endometrium exists in the mode.
The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
