Rubber damping sheets 93 are respectively arranged on two surfaces of the sliding groove, which are contacted with the movable sliding block, so that friction force between the movable sliding block 91 and the long hole 97 is increased to prevent the movable sliding block from slipping, grading teeth 94 are arranged on the rubber damping sheets 93 at intervals, and the function of the grading teeth is that a doctor knows the uterus dilating degree of the uterus dilating rod at the moment. The inner side of the movable slider 91 is connected with a brake column 92, the tail end of the brake column 92 is connected with the pull rod 3, and the pull rod is controlled to move up and down through the brake column 92. In this embodiment, a friction sleeve 95 is fixedly sleeved outside the pull rod 3 at the joint with the brake column 92, a cylindrical groove 96 is formed on the outer wall of the friction sleeve 95, and the end part of the brake column 95 is clamped in the cylindrical groove 96, so that the friction sleeve 95 and the pull rod 3 move together with the brake column 92. When the movable slider 91 is pushed down, the brake column 92 moves downwards along with the movable slider, meanwhile, the brake column 92 drives the friction sleeve 95 and the pull rod 3 to move downwards, and then the upper tension spring 7 stretches to press the upper sleeve 5 to move downwards, so that the upper sleeve 5 presses the elastic arch bar 4 to expand outwards, and the bending radian of the elastic arch bar 4 is adjusted to realize uterus expansion.
The end of the uterus dilating head 2 is provided with an inner suction hole 10, the outer end of the rod body 1 is provided with an outer suction hole 11, a conduit 12 communicated with the inner suction hole 10 and the outer suction hole 11 is arranged in the rod body 1, a plug 13 is arranged at the inner suction hole 10, the plug 13 seals the inner suction hole 10, a pull rope 14 penetrates through the conduit 12, one end of the pull rope 14 is connected with the plug 13, the other end extends out of the outer suction hole 11, an end cap 15 is arranged at the outer end of the rod body 1, the end cap 15 seals the outer suction hole 11, and the outer end of the pull rope 14 is fixed on the inner wall of the end cap 15. After the uterus dilating is completed, the end cap 15 is pulled out, the end cap 15 is pulled to pull the pull rope 14 outwards, the plug 13 at the inner suction hole 10 is pulled out of the catheter 12 by the pull rope 14, and at the moment, the catheter 12 is externally connected with a negative pressure device for communication, so that residual tissues in the uterus can be sucked out through the catheter 12. The uterus sucking rod does not need to be replaced additionally, so that the surgical damage and infection risk are greatly reduced, and the uterus dilating and uterus sucking operations are completed on one uterus dilating rod.
In the uterus dilating process of the rod body 1, the upper tension spring 7 stretches downwards under tension, and as the upper part of the rod body 1 enters the uterus and is made of elastic materials, the upper part of the rod body 1 is subjected to the downward tension of the upper tension spring 7, so as to further bend the rod body 1 from an initial state angle to bend one side of the inner suction hole 10 at the end part of the uterus dilating head 2, the inner suction hole 10 can be attached to the inner wall of the uterus, and compared with the suspension adsorption in the uterus, the inner suction hole 10 at the end part of the uterus dilating head 2 is more convenient for adsorbing residual substances on the inner wall of the uterus after being bent to one side, thereby ensuring the cleaning of the uterus.
Example 2: the uterus dilating rod of this embodiment mainly includes differences from embodiment 1.
In this embodiment, as shown in fig. 12, a lower tension spring 8 is connected to the lower end of the pull rod 3, the other end of the lower tension spring 8 is fixed inside the rod body 1, and the lock body is disposed between the lower tension spring and the sleeve and connected with the pull rod. When the sum of the elasticity of the lower tension spring 8 and the force of hand pulling is larger than the sum of the elasticity of the upper tension spring and the elasticity of the elastic arch bar, the movable slider 91 moves downwards, so that the lower tension spring 8 has the function of providing a pulling-down force, reducing the force of hand pulling, enabling the hand to easily push the movable slider 91, and enabling the movable slider 91 to drive the brake column 92 and further drive the pull rod 3 to move up and down.
