Abstract
A kind of intrauterine device holder, is made of wire, and wire both ends press part made of metal, the end set chase of wire.The present invention is to reduce metal parts by following two aspects to fall off from holder risk：1) keep rack surface uneven, increase the frictional force between holder and metal parts, increase the initial binding force of metal parts and holder.2) under the action of uterine cavity liquid, metal parts forms bimetallic galvanic corrosion system with holder, and the metal parts as anode is accelerated in itself and the corrosion rate of holder contact position, and corrosion rate is related with Galvanic Current size；The end set chase of the intrauterine device stent wire of the present invention can increase the contact area of holder and metal parts, and Galvanic Current is made to reduce, and metal parts reduces in itself and the corrosion rate of holder contact position, to delay the reduction of binding force.
Description
Technical field
The present invention relates to a kind of contraceptive more particularly to a kind of intrauterine devices.
Background technology
Largely holder, the end one of holder is made using stainless steel wire or TiNi shape-memory alloy wires in intrauterine device
As using being screwed on around spring, handled by the way of crotch docking, set silica gel sheath, pressure silica gel block or pressure metal parts (mainly copper particle).
The processing mode of wherein pressure metal parts is usually by the end of holder through in the hole of metal parts, using punching press
Mode holder and metal parts are pressed to together, make metal parts be difficult fall off from holder, but intrauterine device place
To after uterus, under the action of uterine cavity liquid, metal parts corrodes with holder, and the binding force of the two is gradually reduced, metal
The risk that part falls off from holder gradually increases.
Invention content
The purpose of the present invention is overcoming above-mentioned the deficiencies in the prior art, a kind of intrauterine device holder is provided, the holder energy
Enough reduce the risk that metal parts falls off from holder.
To achieve the above object, the present invention is realized using following technical scheme：
A kind of intrauterine device holder, is made of wire, and wire both ends press part made of metal, wire
End set chase.
It is equipped with several chases in the side of the end of the wire.
Several chases are respectively equipped in the both sides of the end of the wire, both sides chase shifts to install.
Compared with prior art, the beneficial effects of the invention are as follows：
The present invention is to reduce metal parts by following two aspects to fall off from holder risk：
1) keep rack surface uneven, increase the frictional force between holder and metal parts, increase metal parts
With the initial binding force of holder.
2) under the action of uterine cavity liquid, metal parts forms bimetallic galvanic corrosion system (at surface with holder
The influence of the factors such as science and engineering skill, metal parts may be that anode may also be cathode, but over time metal parts at
For the anode of galvanic corrosion system, holder becomes the cathode of galvanic corrosion system), the metal parts as anode is in itself and holder
The corrosion rate of contact position is accelerated, and corrosion rate is related with Galvanic Current size；The intrauterine device holder gold of the present invention
The contact area of holder and metal parts can be increased by belonging to the end set chase of silk, so that Galvanic Current is reduced, metal parts is at it
Reduce with the corrosion rate of holder contact position, to delay the reduction of binding force.
Description of the drawings
Fig. 1 is the bracket end diagrammatic cross-section (embodiment 1) of unilateral chase.
Fig. 2 is the bracket end diagrammatic cross-section (embodiment 2) of bilateral chase.
The bracket end and the diagrammatic cross-section after metal parts pressing that Fig. 3 is unilateral chase.
In figure：1- bracket ends, 2- metal parts, 3- chases.
Specific implementation mode
The present invention is described in detail below in conjunction with the accompanying drawings, it should be noted that the present invention implementation be not limited to it is following
Embodiment.
A kind of intrauterine device holder, is made of medically acceptable wire, and wire both ends pressing metal is made
Part, chase 3 is arranged in the end (bracket end 1) of wire.
Embodiment 1：
See Fig. 1, Fig. 3, intrauterine device holder is that (such as stainless steel is made of a kind of medically acceptable wire
Silk), several chases 3 are made in the side of bracket end 1 by the way of being stamped or cut out.By bracket end 1 through metal zero
In the hole of part 2, metal parts 2 uses copper particle, punching press that holder and copper particle is made to combine.
Embodiment 2：
See Fig. 2, intrauterine device holder is that (such as TiNi shape memories are made of a kind of medically acceptable wire
B alloy wire), several chases are respectively equipped in the both sides of the end of the wire, both sides chase shifts to install.In contraceptive
Bracket end installs copper particle, and mounting means is the same as embodiment 1.
Claims (3)
1. a kind of intrauterine device holder, which is characterized in that be made of wire, wire both ends press zero made of metal
Part, which is characterized in that the end set chase of wire.
2. a kind of intrauterine device holder according to claim 1, which is characterized in that the side in the end of the wire
Equipped with several chases.
3. a kind of intrauterine device holder according to claim 1, which is characterized in that the both sides in the end of the wire
Several chases are respectively equipped with, both sides chase shifts to install.
