The family planning that China carries out from the seventies, the womb contraceptive ring that is adopted mostly are the circular metal rings, and its cost of manufacture is low, are formed by the filament snare, and form is external diameter 22mm, internal diameter 17mm, ring diameter 2.1mm.The whole nation continues from the city to the rural area always and uses the nineties latter stage, therefore, the adults women's that needs family planning of this all ages and classes section must be inserted this intrauterine device, the elderly woman of nearly 200,000,000 populations needed to take out in specific period at present, because health difference, endocrine hormone changes in the body, the uterus of woman about 40 years old to 50 years old, atrophy gradually, intrauterine device exists the uterus will influence the healthy of women, on the other hand, the circular metal womb contraceptive ring of inserting, the part ring body easily is embedded into uterus neck body and bottom, has caused the part metals ring to expose in uterine cavity, because of health hormonal change every month when in the period, have the reason of foreign body in the uterine cavity, endometrium comes off, and causes hemorrhage more, other pathological changes might take place change, therefore, need in time to take out.

Traditional ring instrument of getting with prolong the apparatus of usefulness, be a kind of very common hook, part vertical bar metal is as probe, its length has two, 30 centimeters.By the Position Approximate of the clear and definite intrauterine device of probe, reuse hook hook goes out during operation.In the practical situation, intrauterine part intrauterine device usually occurs and be embedded into uterus neck body and bottom, use this hook easily to cause becket to break, intrauterine device is drawn into the filament shape and disconnects, be trapped between cervix uteri body and the bottom, what have gets to come out, and must adopt operation to take out.Therefore, the process of repeatedly getting ring has easily caused woman's body and mind misery, and increases the weight of economy and mental burden.Along with the development of modern science, can adopt the hysteroscope method to get this womb contraceptive ring, but hysteroscope cost height, the minority provincial hospital just can be afforded, and comes down to the aircraft increasing and bombards mosquito, and financial burden is too heavy, vast rural area can't be promoted, and loses the clinical practice meaning.Up to the present, also do not have a kind of not only simply, but also the device for taking out of intrauterine contraceptive device (IUD) tool of saving trouble solve this problem.

Summary of the invention

The purpose of this utility model is exactly in order to address the above problem, and provides a kind of simple in structure, and cost is low, and is easy to use, the womb contraceptive ring forceps for hook taking that success rate is high.

Technical solution of the present utility model:

A kind of womb contraceptive ring forceps for hook taking, it is characterized in that it is by blood vessel jaw type handle, pipe box and axis are formed, in forward two working arms in the cross point of blood vessel jaw type handle, the front end of a working arm and pipe box tail end are connected, the front end of another working arm and middle shaft tail end are connected, and the axis activity is located in the pipe box, the position integral body that its front end stretches out pipe box is connected with the question mark shaped crotch, the part at the corresponding crotch of the pipe box front end outer wall back side has groove one, so that when blood vessel jaw type handle folds, axis can drive the rear portion one of crotch and take in the pipe box in the same way, makes the gib head medial border of crotch and the front port interlock of pipe box clamp intrauterine device or foreign body.

This utility model is simple in structure, its hook pincers caliper is according to the uterus angle that turns forward, can be bent into the different directions angle and enter cervix uteri, to body of uterus, bottom, combined effect with metal bougie, hook had both reduced the process that patient repeatedly gets ring, reduced again because of getting the misery that the ring failure causes, and eliminate thought and burden economically, reach the ring success rate excessively and be further enhanced.Can also under TV, get comparatively complicated thread foreign body.Because it is simple, practical, cheap that this utility model is made, so alleviated outside patient's the financial burden, applying of the vast rural area of being more convenient for has the important clinical application value to China's family planning work.

The specific embodiment

As Fig. 1, womb contraceptive ring forceps for hook taking of the present utility model, it is by blood vessel jaw type handle 1, pipe box 2 and axis 3 are formed, in forward two working arms in the cross point of blood vessel jaw type handle 1, the front end of a working arm and pipe box 2 tail ends are connected, the front end of another working arm and axis 3 tail ends are connected, and axis 3 activities are located in the pipe box 2, the position integral body that its front end stretches out pipe box 2 is connected with question mark shaped crotch 4, the part at the corresponding crotch of pipe box 2 front end outer walls 4 back sides has groove 5 one, so that when blood vessel jaw type handle 1 folds, axis 3 can drive the rear portion one of crotch 4 and take in the pipe box 2 in the same way, makes the gib head medial border of crotch 4 and the front port interlock of pipe box 2 clamp intrauterine device or foreign body.

This utility model in off position down, be a circular integral body, width 5mm, thickness 2.5mm, the length of coupler body ovalize 8mm, at circular whole the place ahead pipe box on coupler body, be square and meet with the coupler body inboard, this intersection just forms the main body of hook pincers, and when opening, square pipe box (2.5mm) is enclosed within (2.3mm) on the coupler body, and (with the coupler body is axis, quadrate extension holds axis), prolong coupler body and overlap into tubulose backward, form support body, coupler body is by the tubulose support body fulcrum of section blood vessel jaw type far away, coupler body extends through fulcrum and is and moves back and forth, and it is 5-8mm that coupler body and square pipe box form the motion spacing.

Hand control by the blood vessel jaw type, adopt white rust steel material and red copper material, cover hook pincers stretch into intrauterine in off position down and are a probe, and the coupler body of the trocar sheath when opening is the crotch of question mark shaped, hook circular metal ring, the top of pipe box is when the nearly bent circular arc of crotch, one open slot 8mm is arranged, enter pipe box to guarantee the part that crotch protrudes, the top of pipe box forms square, as with the interlock of crotch medial border, meet the interlock foreign body.This hook pincers interlock has two kilograms power (by two kilograms of weights of pincers hook interlock, being enough to bear gmatjpdumamics, the traction force of getting ring).

The hand control of crotch direction and blood vessel jaw type is equidirectional, therefore, can also make the hook pincers series that to regulate different directions as required, the type hook pincers of duckbilled flat, so that be in certain location, reach easy to use, coordinate the process of interlock flexibly at different angles, direction, becket.
