Abstract
The utility model provides a new style contraceptive: an NiTi shape memory alloy oviduct embolism. By using the characteristics of the temperature and the shape of an NiTi-shaped memory alloy, super elasticity, good biocompatibility and tightness, when the embolism is embedded into the oviduct and can automatically recover shaping heat treatment, the specific shape is set and is inlaid in the oviduct to reach the purpose of clogging the oviduct. When the embolism part carries out local cooling, the embolism is softened and is conveniently taken out with a clamp or other special tools. The utility model has the advantages of high contraception success rate and high salpinx recovery rate.
Description
This utility model relates to a kind of Embolism for fallopian tube that is used for female contraception, belongs to the improvement of contraceptive techniques.
In existing contraceptive techniques, still there are not a kind of ideal contraceptives.Cover safe in utilization then greatly reduces life quality, and the success rate of contraception is lower; Last ring (promptly using intrauterine device (IUD)), most women have untoward reaction such as menorrhagia, menstrual period pain; Oral contraceptive, most medicines disturb the human endocrine system, and there is influence in various degree the aspects such as metabolic function, cardiovascular system, liver function, blood coagulation and descendant inheritting of human body, and it is unfavorable to take for a long time health; Sterilization operation exist recanalization rate low, need undergo surgery problem such as wound is big; The medicine thromboembolism is then because medicine mixes mutually with oviducal interior mucosal tissue after implanting fallopian tube, after use after a while, the medicine thromboembolism sticks in the fallopian tube and produces chemical reaction on the mucosa, form inseparable connection, be difficult to separate again, both influenced the height of its recanalization rate, may produce untoward reaction to the fallopian tube inner chamber again, disturb the human endocrine system, unfavorable to health.
The purpose of this utility model is intended to overcome deficiency of the prior art, a kind of comparatively ideal contraceptive device is provided, neither can produce adverse side effect and influence life quality, need not to carry out big operation again each function of human body, and the success rate height of practising contraception, Embolism for fallopian tube that recanalization rate is high.
Embolism for fallopian tube described in the utility model is the heat treated coil spring shape thromboembolism made from the NiTi shape-memory alloy wire with geometry in particular of process typing.During use, this thromboembolism is placed fallopian tube, its principle is when temperature is lower than the transformation temperature of shape-memory alloy wire, and this helical spring is in soft condition, can pull into one-level helical spring or monofilament like a cork; And in the fallopian tube with this helical spring implant into body, under the effect of body temperature, when this helical spring temperature is higher than its transformation temperature, the elastic modelling quantity of NiTi shape-memory alloy wire increases severely, has superelastic properties, the geometry in particular of setting when this helical spring automatically restores to the typing heat treatment simultaneously (as cylindrical or date core shaped), be embedded in the fallopian tube, in the fallopian tube mucosal tissue within a certain period of time (about 1～3 week) on this helical spring, adhere to, reach and block oviducal purpose.When needs are logical again, as long as the part cooling is carried out in the Embolism for fallopian tube position, make this helical spring temperature be lower than the transformation temperature of used NiTi marmem, this helical spring is in soft condition, clamp this helical spring one end with operation clip or other specific purpose tool, pull into one-level helical spring or alloy filaments and take out, take out light, convenient.
Be further to strengthen block capability of the present utility model, and reduce when taking out, be attached with medical nylon fiber on the NiTi shape-memory alloy wire of above-mentioned coil spring shape thromboembolism the damage of mucosal tissue in the fallopian tube.This medical nylon fiber can be at the fiber or the silk thread of the medical macromolecular materials of human body midium or long term implantation for the inanimate object toxicity that can for a long time implant in human body, the medical nylon fiber that good biocompatibility is arranged or other, and its diameter is between 0.001-1.0mm.
According to actual needs, above-mentioned coil spring shape thromboembolism is one-level or secondary or the multiple coil spring-like thromboembolism that turns to the NiTi shape-memory alloy wire.The geometry in particular that this coil spring shape thromboembolism is finalized the design through Overheating Treatment is generally the cylinder bodily form or date core shaped or double horn shape or list is tubaeform or the cylinder bodily form of a cylindrical or headband list cone of the bipyramid bodily form or taper or double headed roller cone.
This utility model is owing to adopt the structure of NiTi marmem as Embolism for fallopian tube, because NiTi marmem inanimate object toxicity, have good biocompatibility, can in human body, implant for a long time, and utilize its unique temperature shape characteristic that NiTi marmem Embolism for fallopian tube is implanted easily, convenient to remove, can fully guarantee its contraception success rate height, the recanalization rate height, operation is simple, can observe under the X-ray, can not produce damage fallopian tube.Simultaneously because NiTi marmem thromboembolism is pure physics thromboembolism, utilized mucosal tissue adhering in the fallopian tube to foreign body, thereby do not resemble the stimulation to the uterus of heavy metal ion (as copper ion) or medicine is arranged the ring (use intrauterine device (IUD)), side effect such as can not cause that menses increase; Do not resemble oral contraceptive yet the physiological system of human body is exerted an influence, life-time service can be not unhealthful, do not reduce life quality, is a kind of comparatively ideal contraceptive device.
