Abstract
The invention discloses a contraceptive plug, which comprises a guide rod, at least one radial-pattern supporter windingly connected with the guide rod, and a film attached to the supporter. The guiderod can be easily placed in the interstitial portion of fallopian tube, the top end of the radial-pattern supporter can be embedded in uterine muscles to prevent the contraceptive plug from moving andfalling, and the film attached to the supporter can efficiently prevent sperms entering the fallopian tube, so as to achieve contraceptive effect and achieve high success rate of contraception. Becau se the radial-pattern supporter is deformable compared with bumps with solid planar cross section, therefore, the inventive contraceptive plug has good flexibility.
Description
Technical field
The present invention relates to a kind of sterilization embolus, particularly place the sterilization embolus of matter portion between fallopian tube.
Background technology
Because do not need to operate on, avoided the damage of abdominal incision and internal organs through the hysteroscope tubal sterilization, had broad application prospects the human abdomen.Chinese patent 200520051371.9 discloses a kind of sterilization embolus of being made by marmem, and it comprises guide bar and around at least one projection that is connected on the guide bar.Its advantage is sterillization success rate height, places simply, and little to the human body side effect.But because the projection cross section on the guide bar is the physical plane, axially not yielding along guide bar, therefore very high for the requirement of marmem material and processing thereof, so cost is high.
Summary of the invention
It is easy to the purpose of this invention is to provide a kind of distortion, and preparation is simple, the sterilization embolus that cost is low.
In order to achieve the above object, sterilization embolus of the present invention comprises guide bar, at least one support and thin film, support is around being connected on the guide bar, thin film sticks on the support, and guide bar and the thin film cross section that sticks on the support are disc, and the length of guide bar is 4mm to 15mm, diameter is 0.2mm to 1.8mm, described support is radial, and the length of every radial support is 1mm to 5mm, and thickness is 0.1mm to 0.8mm.
At least there is the groove around guide bar on one side of close radial support on the guide bar surface, and the length of groove is 1mm to 5mm, and the diameter of the guide bar at trench portions place is 0.1mm to 1.7mm.
One hole is arranged on guide bar, be convenient to put into and take out sterilization embolus.
Described sterilization embolus is made by the TiNi alloy, and wherein the content of Ni is 56%～58%, and surplus is Ti.
Sterilization embolus guide bar of the present invention can be inserted oviducal matter portion easily, the top of radial support can embed the flesh layer, sterilization embolus is moved and come off, the thin film that sticks on the support can stop sperm to enter fallopian tube effectively, reaches the effect of sterillization and can reach the success rate of very high sterillization.Because radial support is the projection easy deformation of physical plane than the cross section, so the present invention has the easy beneficial effect of distortion.Simultaneously, the top of radial support and oviducal contact surface are very little, can not cause than macrolesion it, thereby very little to the side effect of human body.The present invention also has preparation simple in addition, the advantage that cost is low.
