Sterilization boltTechnical 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 organsDamage, have broad application prospects.Chinese patent 201020118979.X is disclosed and a kind of is made up of marmemSterilization bolt, it includes guide bar, connecting bracket, ring support and sticks to film on ring support and connecting bracket.This is specialProfit support radial in suitable temperature can fix side axial direction and close up along guide bar, insert temperature after interstitial tubalRadial 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 supportUterus, reaches the effect of sterilization.Patent construction is complicated, high cost, because sticking to ring support with the film of link supportDrag 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 withHeight, 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 additionIt 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 withThe 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 barLength 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 is0.1mm 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% toThe 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 equalLaunch 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 andThin 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 pointThe two parts opened, can individually temper the memory function of thin slice, make it at appropriate temperatures can be without fixed directivity around guide barCondensation, can uniformly launch after placing interstitial tubal.Simple structure of the present invention, easy to manufacture, low cost, without in supportThe aspects such as material, the precision of geomery and processing technology have requirement high；Additionally, thin slice is different from guide bar material, noBe 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-directionProperty, simplify manufacturing process.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of specific embodiment of the invention.
Specific embodiment
Sterilization bolt of the invention is described further below in conjunction with the accompanying drawings.
Embodiment 1：As shown in figure 1, sterilization bolt of the invention includes at least one thin slice 1 and the guiding being welded on thin sliceBar 2.Thin slice is made up of TiNi alloy, and wherein the weight percentage of Ni is 56%, and remaining is Ti, and guide bar is by stainless steel metalIt is made.The cross section of thin slice 1 and guide bar 2 is disc.A diameter of 1mm of thin slice 1, thickness is 10um, and the length of guide bar is2mm, a diameter of 0.2mm.There are the groove 3 around guide bar, the length of groove 3 near one side of thin slice 1 on the surface of guide bar 2It is 0.2mm, a diameter of 0.2mm of the guide bar where trench portions.Thin slice 1 can be at 10 DEG C of softening temperature without fixed directivityAround guide bar condensation, behind the interstitial portion that sterilization bolt is inserted into human body fallopian tubal, in the shape memory temperature close to body temperatureUnder degree, thin slice 1 can recover original shape, and the muscle layer of embedded interstitial tubal will not make sterilization bolt move and come off, and byThe gapless between thin slice and fallopian tubal inwall, effectively blocks fallopian tubal, so can reach the success rate of sterilization very high.LeadingDrawing on bar has a hole 4, can be used to bolt line, facilitates the placement and taking-up of sterilization bolt.
Thin slice of the present invention is different from guide bar material, is not an entirety, is welded after can individually tempering the memory function of thin sliceIt is connected together, thin slice has shape memory function, and guide bar keeps the consistency of shape.In addition, thin slice is ultra-thin, it is solid to be condensed nothingDetermine directionality, be simple to manufacture, low cost.
Embodiment 2：Sterilization bolt of the invention includes at least one thin slice 1 and the guide bar 2 being welded on thin slice.Thin slice isIt is made up of TiNi alloy, wherein the weight percentage of Ni is 56.5%, and remaining is Ti, and guide bar is made up of stainless steel metal.It is thinThe cross section of piece 1 and guide bar 2 is disc.A diameter of 2mm of thin slice 1, thickness is 50um, and the length of guide bar is 3mm, diameterIt is 0.5mm.There is the groove 3 around guide bar near one side of thin slice 1 on the surface of guide bar 2, the length of groove 3 is 0.5mm,A diameter of 0.3mm of the guide bar where trench portions.Thin slice 1 can at 10 DEG C of softening temperature without fixed directivity around guidingBar is condensed, behind the interstitial portion that sterilization bolt is inserted into human body fallopian tubal, close under the shape memory temperature of body temperature, and thin slice1 can recover original shape, the muscle layer of embedded interstitial tubal, and sterilization bolt will not be made to move and come off, but due to thin slice withGapless between fallopian tubal inwall, effectively blocks fallopian tubal, so can reach the success rate of sterilization very high.Have on guide barOne hole 4, can be used to bolt line, facilitate the placement and taking-up of sterilization bolt.
