Detailed Description

The present invention will be further explained with reference to the drawings and examples.

Example 1: an expanding and sucking integrated uterine dilating rod is shown in figures 1-11 and comprises a rod body 1 and a uterine dilating head 2 which is integrally arranged at the tail end part of the rod body and forms an included angle alpha with the rod body, wherein the included angle alpha between the rod body and the uterine dilating head is 160-172 degrees, the shape of the included angle alpha is consistent with the shape of a uterus, and the included angle alpha can more easily enter the uterus. The hollow cavity is formed in the rod body 1, the capacity expanding body used for adjusting the diameter of the rod body is arranged in the hollow cavity, the capacity expanding body comprises a pull rod and a plurality of elastic arch bars 4 which are uniformly distributed around the pull rod 3, the upper end of the pull rod 3 is connected with an upper tension spring 7, and the upper end of the upper tension spring 7 is fixed at the position, close to the upper part, of the inner wall of the rod body. In the embodiment, 8 elastic arch bars are uniformly distributed around the pull rod, the pull rod 3 is arranged at the center of the inner cavity of the rod body along the length direction of the rod body, the upper end part and the lower end part of each elastic arch bar 4 are gathered towards the center respectively and are sleeved on the pull rod 3 in a sliding manner, so that the elastic arch bars 4 can move along the pull rod 3; the middle parts of the 8 elastic arch bars are respectively bulged outwards in an arc shape in the direction departing from the pull rod 3, so that the elastic arch bars 4 are integrally formed into a lantern shape, the elastic arch bars 4 are bulged outwards to be in contact with the inner wall of the rod body 1, the rod body 1 is extruded outwards, the diameter of the rod body is enlarged, and the capacity expansion effect is achieved.

An upper sleeve 5 and a lower sleeve 6 are respectively sleeved on the pull rods at the upper end and the lower end of the elastic arch bar 4, wherein the upper sleeve 5 is movably sleeved on the pull rod 3, and the upper sleeve 5 can move on the pull rod 3 between the upper tension spring 7 and the elastic arch bar 4. The lower sleeve 6 is fixedly arranged at the lower part of the rod body 1, specifically, the upper part of the rod body 1 entering into the uterus is made of elastic materials, the part of the lower part of the rod body 1 used for being held by a doctor is made of non-elastic materials, two parallel limiting rings 16 are correspondingly arranged on the inner wall of the rod body 1 at the holding position of the doctor, a check ring 17 is integrally arranged on the outer wall of the lower sleeve 6, the check ring 17 is clamped in the two limiting rings 16 to fix the lower sleeve 6 on the inner wall of the rod body 1, a pull rod positioned at the lower end of the elastic arch bar 4 penetrates through the lower sleeve 6, and the elastic arch bar 4 is clamped at the upper end part of the lower. When the upper sleeve 6 moves downwards, the lower end of the elastic arch bar 4 is clamped at the upper end part of the lower sleeve 6, namely the lower end of the elastic arch bar 4 cannot move, so that the upper sleeve 5 presses the elastic arch bar 4 to expand outwards, and the diameter of the rod body 1 is enlarged to achieve the expansion effect.

The lower end of the pull rod 3 is connected with a lock body 9, the lock body comprises a movable sliding block 91 and a braking column 92, the side wall of the rod body 1 is provided with a long hole 97, sliding grooves are arranged on two sides of the movable sliding block 91, the movable sliding block 91 is clamped in the long hole 97 on the side wall of the rod body 1 through the sliding grooves, and the movable sliding block 91 can move along the long hole 97 by pushing. The two sides of the sliding groove, which are contacted with the movable sliding block, are respectively provided with a rubber damping sheet 93, the 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 sheet 93 at intervals, and the grading teeth have the function of enabling a doctor to know the uterine dilating degree of the uterine dilating rod at the moment. The inner side of the movable slide block 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 post 92, a post-shaped groove 96 is formed in the outer wall of the friction sleeve 95, and the end of the brake post 95 is clamped in the post-shaped groove 96, so that the friction sleeve 95 and the pull rod 3 move together with the brake post 92. When the movable slider 91 is pushed down, the braking column 92 moves downwards along with the movable slider, meanwhile, the braking column 92 drives the friction sleeve 95 and the pull rod 3 to move downwards, further, the upper tension spring 7 extends to press the upper sleeve 5 to move downwards, then, the upper sleeve 5 presses the elastic arch strip 4 to expand outwards, and further, the bending radian of the elastic arch strip 4 is adjusted to realize uterus expansion.

Open at the tip of expanding palace head 2 and have interior hole 10 of inhaling, stick 1 outer end is equipped with outer hole 11 of inhaling, be provided with in the stick 1 with interior hole 10, the pipe 12 of inhaling hole 11 intercommunication outward to interior hole 10 department installs end cap 13, end cap 13 is with inhaling hole 10 shutoff in, it has stay cord 14 to run through in pipe 12, stay cord 14 one end is connected with end cap 13, the other end stretches out from inhaling hole 11 outward, install end cap 15 in the outer end of stick 1, end cap 15 is with inhaling hole 11 shutoff outward, the outer end of stay cord 14 is fixed in end cap 15 inner wall. After the uterus dilatation is completed, the end cap 15 is pulled out, the end cap 15 is pulled at the same time, the pull rope 14 is pulled outwards, the plug 13 at the position of the inner suction hole 10 is pulled out of the catheter 12 by the pull rope 14, the catheter 12 is communicated with an external negative pressure device at the moment, and residual tissues in the uterus can be sucked out through the catheter 12. The uterus suction rod does not need to be replaced additionally, thereby greatly reducing the operation injury and infection risk and leading the two operations of uterus dilatation and uterus suction to be completed on one uterus dilatation rod.

In the palace in-process is expanded to barred body 1, go up extension spring 7 and draw the power downwardly extending, because 1 upper portion of barred body gets into intrauterine for the elastic material, 1 upper portion of barred body receives the lower pulling force of extension spring 7, so as shown in fig. 9, barred body 1 is further crooked by initial condition's angle, makes the interior suction hole 10 one side bending of expanding 2 tip of palace head, makes interior suction hole 10 can attach in uterus inner wall, for in the unsettled absorption in uterus, the utility model discloses expand the interior suction hole 10 of 2 tip of palace head and be convenient for adsorb the residual material of uterus inner wall after to one side bending more, guarantee that the clear palace is clean.

Example 2: the point of difference between the expansion and suction integrated uterine dilator of the present example and that of example 1 will be mainly described.

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 1, and the lock body is disposed between the lower tension spring and the sleeve and connected to the pull rod. When the sum of the elastic force of the lower tension spring 8 and the downward pulling force of the upper hand is greater than the sum of the elastic force of the upper tension spring and the elastic arch bar, the movable slider 91 moves downward, so that the lower tension spring 8 can provide a downward pulling force, the downward pulling force of the hand is reduced, the hand can easily push the movable slider 91, and the movable slider 91 drives the brake column 92 to further drive the pull rod 3 to move up and down.
