Abstract
The utility model discloses a ring removing device, which belongs to the medical instruments field. The ring removing device comprises a clamping end and a hand holding end, a circular ring is respectively arranged on the two hand holding handles of the hand holding end, opposite semi-circle hole shaped clamping parts are arranged on the two clamping handles of the clamping end, when the two clamping handles are butted, a circle hole shaped clamping part is formed, regularly arranged heaves are arranged in each semi-circle hole shaped clamping part, and opposite gear shaped self-locking structures are arranged on the two hand holding handles of the hand holding end. Because the heaves are additionally arranged in the circular hole shaped clamping part of the clamping end in the ring removing device, when the contraceptive device is clamped, the frictional force is increased, the ring removing device is not easy to be dropped out, simultaneously, a self-locking device is additionally arranged at the hand holing end, after self locking, the hand can be liberated from the hand holding end, and the hand need not to clamp emphatically all the while.
Description
Technical field
This utility model relates to a kind of medical apparatus, particularly a kind of device for taking out of intrauterine contraceptive device (IUD).
Background technology
Birth control apparatus is a kind of contraceptive device commonly used.When finish the service life of birth control apparatus, need birth control apparatus be taken out from cavity of uterus with device for taking out of intrauterine contraceptive device (IUD).Its structure of device for taking out of intrauterine contraceptive device (IUD) commonly used at present offers poroid clamping part at bare terminal end, the inner surface smoother of poroid clamping part as shown in Figure 1, simultaneously owing to birth control apparatus also smoother, therefore slippage easily in clamping process, perhaps clamping incessantly causes and gets the ring failure.And handheld terminal do not have auto-lock function yet, needs firmly to clamp birth control apparatus in clamping process always, causes the birth control apparatus slippage easily yet.
Summary of the invention
Task of the present utility model is to provide a kind of device for taking out of intrauterine contraceptive device (IUD), and it has not eely advantage when winning birth control apparatus.
Its technical solution is:
A kind of device for taking out of intrauterine contraceptive device (IUD), comprise bare terminal end and handheld terminal, respectively have an annulus on two hand holding handles of handheld terminal, offer the poroid clamping part of relative semicircle on two grip shank of bare terminal end, when two grip shank butt joints, form the circular hole clamping part, be provided with projection in the described half and half circular hole clamping part.
Above-mentioned projection is rule and arranges in the poroid clamping part of semicircle.
Two hand holding handles of above-mentioned handheld terminal are provided with relative profile of tooth self-locking structure.
The beneficial effects of the utility model are: owing to set up projection in the circular hole clamping part of bare terminal end, increased frictional force when the clamping birth control apparatus, should not come off, simultaneously increased self-locking device at handheld terminal, after self-locking, hands can free from handheld terminal, the clamping of need not always exerting oneself.
Description of drawings
Fig. 1 is the prior art constructions sketch map;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the A portion enlarged drawing of Fig. 2.
The specific embodiment
Describe below in conjunction with 2,3 pairs of this utility model of accompanying drawing: this utility model device for taking out of intrauterine contraceptive device (IUD), comprise bare terminal end 1 and handheld terminal 2, the end of two hand holding handles 21 of handheld terminal 2 respectively has an annulus 22, be provided with relative profile of tooth self-locking structure 23 at annulus 22 with the connecting portion of hand holding handle 21, two grip shank 11 ends at bare terminal end 1 offer the poroid clamping part 12 of relative semicircle, in order to increase frictional force, make the gripping object difficult drop-off, in the poroid clamping part 12 of semicircle, be provided with the projection 13 that rule is arranged.
Certainly, protection domain of the present utility model is not limited to the foregoing description, so long as those of ordinary skill in the art is through creatively improving, and all should be within protection domain of the present utility model.
Claims (3)
1, a kind of device for taking out of intrauterine contraceptive device (IUD), comprise bare terminal end and handheld terminal, respectively have an annulus on two hand holding handles of handheld terminal, offer the poroid clamping part of relative semicircle on two grip shank of bare terminal end, when two grip shank butt joints, form the circular hole clamping part, it is characterized in that being provided with projection in the described half and half circular hole clamping part.
2, device for taking out of intrauterine contraceptive device (IUD) according to claim 1 is characterized in that described projection is rule and arranges in the poroid clamping part of semicircle.
