CN101779995B - Sterilization stopper - Google Patents

Abstract

The invention discloses a sterilization stopper, which comprises a guide rod, a membrane, a connecting bracket and an annular bracket. The annular bracket surrounds the periphery of the guide rod and is connected with the guide rod through the connecting bracket; the membrane is adhered to the annular bracket and the connecting bracket; the guide rod can be conveniently embedded into an interstitial part of an oviduct; the outer edge of the annular bracket can be uniformly embedded into a muscular layer so that the sterilization stopper does not move and fall off and the shape, the deformation action and the force are kept consistent without relatively high requirements on precision, processing technique and the like of the material, the shape and the size of the bracket; and in addition, because the membrane is adhered to the annular bracket and the connecting bracket and no clearance is left between the membrane and the muscular layer of the interstitial part of the oviduct, the sterilization stopper can completely prevent sperms from entering a uterus to ensure the effect of sterilization. The sterilization stopper also has the advantages of simple structure, easy manufacturing and low cost.

Description

Sterilization embolus

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 200810030905.8 discloses a kind of sterilization embolus of being made by marmem, and it comprises guide bar and around at least one group of radial support that is connected on the guide bar, and sticks to the thin film on the support.The guide bar of this patent can be inserted oviducal matter portion, and the top of radial support can embed the flesh layer, stops sperm to enter the uterus by the thin film that sticks on the support, reaches the effect of sterillization.But can both embed the unanimity that the flesh layer also keeps shape, deformed movement and dynamics as far as possible owing to will guarantee the top of radial support, therefore having relatively high expectations to the precision of the material of support, geomery and processing technique etc., and, be difficult to sometimes stop sperm to enter the uterus fully and the effect that guarantees sterillization because still may there be tiny gap in matter portion flesh interlayer between thin film and fallopian tube.

Summary of the invention

The objective of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of simple in structure, easy to manufacture, the lower and sterilization effect of cost is sterilization embolus preferably.

For achieving the above object, the present invention includes guide bar, thin film, connection support and ring support, described ring support is looped around the guide bar periphery, and ring support is connected with guide bar by connecting support, on thin film sticks to ring support and is connected support.

As a further improvement on the present invention, guide bar is a disc with the thin film cross section that sticks to ring support, be connected on the support.Can be fit to oviducal shape like this, also be convenient to processing and manufacturing.

Further improve as of the present invention, the length of guide bar is 4mm to 10mm, and diameter is 0.2mm to 1.8mm, the length of every connection support is 0.95mm to 4.5mm, thickness is 0.1mm to 1.0mm, and the width of ring support is 0.05mm to 0.5mm, and thickness is 0.1mm to 1.0mm.

At least there is the groove around guide bar on close one side that connects support on the guide bar surface, and the length of groove is 0.5mm to 2.5mm, and the diameter of the guide bar at trench portions place is 0.2mm to 1.6mm.

One hole is arranged on guide bar, can conveniently place and take out.

The present invention is made by the TiNi alloy, and wherein the percentage by weight of Ti is 43% to 46%, and the percentage by weight of Ni is 54% to 57%.

Sterilization embolus guide bar of the present invention can be inserted oviducal matter portion easily, the outer of ring support can embed the flesh layer equably, sterilization embolus is moved and come off, and can keep the unanimity of shape, deformed movement and dynamics and do not need the precision of material, geomery and have relatively high expectations in aspect such as processing technique at support; In addition and since thin film stick to ring support and be connected support on and and between fallopian tube matter portion flesh interlayer do not have the gap, thereby can stop sperm to enter the uterus fully and guarantee the effect of sterillization.The present invention is simple in structure in addition, easy to manufacture in addition, the advantage that cost is low.
