Abstract
It is high the invention discloses a kind of success rate, place simple, and to the sterilization bolt of human body Small side effects.Sterilization bolt includes at least one thin slice and guide bar.Thin slice is made up of TiNi alloy, and guide bar is made of stainless steel, and guide bar is welded on the center on thin slice two sides.Guide bar can easily be placed into interstitial tubal, and thin slice can be evenly embedded into muscle layer, and sterilization bolt will not be made to move and come off, so as to the combination of sperm and ovum can be prevented effectively, reach the effect of sterilization.Thin slice and guide bar are made up of different materials, can keep thin slice alteration of form when temperature changes, and Shape invariance of the guide bar when temperature changes, the high request in terms of without precision and processing technology in geomery etc..Simple structure of the present invention, easy to manufacture, low cost.
Description
Technical field
The present invention relates to a kind of sterilization bolt, the sterilization bolt of interstitial tubal is especially placed in.
Background technology
Through hysteroscope tubal sterilization because be not required to be operated in human abdomen, it is to avoid abdominal incision and internal organs
Damage, have broad application prospects.Chinese patent 201020118979.X is disclosed and a kind of is made up of marmem
Sterilization bolt, it includes guide bar, connecting bracket, ring support and sticks to film on ring support and connecting bracket.This is special
Profit support radial in suitable temperature can fix side axial direction and close up along guide bar, insert temperature after interstitial tubal
Radial support launches to make the outer of ring support to be embedded in muscle layer during change, prevents sperm from entering by sticking to the film on support
Uterus, reaches the effect of sterilization.Patent construction is complicated, high cost, because sticking to ring support with the film of link support
Drag effect, it is ensured that to support to guide bar fix side axial direction close up and can launch uniform and holding shape of trying one's best,
Deformed movement and dynamics it is consistent, therefore material to support, the precision of geomery and processing technology etc. requirement compared with
Height, and support is identical with guide bar material, is the entirety that cannot be separated, and tempers support memory function difficulty, and film holds in addition
It is yielding, it is impossible to contraceptive effect is completely secured.
The content of the invention
The purpose of the present invention is the shortcoming for overcoming above-mentioned prior art, there is provided a kind of simple structure, easy to manufacture, cost compared with
The preferable sterilization bolt of low and sterilization effect.
To reach above-mentioned purpose, the present invention includes at least one thin slice and the guide bar for being welded on thin slice two sides.
As a further improvement on the present invention, the cross section of thin slice and guide bar is disc.
Further improved as of the invention, a diameter of 1mm to 5mm of thin slice, thickness is 5um to 500um, guide bar
Length be 2mm to 5mm, a diameter of 0.2mm to 1.8mm.
Used as improvement, the length for having the groove around guide bar, groove near one side of thin slice on guide bar surface is
0.1mm to 1.5mm, a diameter of 0.1mm to 1.2mm of the guide bar where trench portions.
As improvement, a hole is provided with guide bar.
Used as improvement, sterilization bolt thin slice of the present invention is made up of TiNi alloy, wherein the percentage by weight of Ti be 43% to
The percentage by weight of 46%, Ni is 54% to 57%, and guide bar is to be made of stainless steel.
Behind the interstitial portion that sterilization bolt of the invention easily inserts fallopian tubal under ultra-thin foil condensed state, thin slice can be equal
Launch to be embedded in muscle layer evenly, sterilization bolt will not be made to move and come off, and can keep the consistent of shape, deformed movement and dynamics and
Thin slice will not be made along the gathering of guide bar axle side fixed-direction because resistance leads to not uniform expansion.Thin slice and guide bar are point
The two parts opened, can individually temper the memory function of thin slice, make it at appropriate temperatures can be without fixed directivity around guide bar
Condensation, can uniformly launch after placing interstitial tubal.Simple structure of the present invention, easy to manufacture, low cost, without in support
The aspects such as material, the precision of geomery and processing technology have requirement high；Additionally, thin slice is different from guide bar material, no
Be an entirety, weld together after the memory function that can individually temper thin slice, in addition, thin slice it is ultra-thin, condensation without fixed-direction
Property, simplify manufacturing process.
