Abstract

The utility model relates to a novel uterine dilator for gynecology, which is formed by connecting a uterus-expanding probe with a conduit and a syringe. The utility model is characterized in that the uterus-expanding probe is formed by sheathing a uterus-expanding membrane on a stainless steel tube, the uterus-expanding membrane is made by knitting elastic wefts and inelastic warps, and latex layers are hung on the internal wall and the external wall of the uterus-expanding membrane. Required size can be achieved by one-time uterus expansion in thirty seconds usually. The utility model has the advantages of rapidness, safety, no pain sense and ideal effect.

Description

Disposable uterus-developing device for gynecology

This utility model is a kind of gynecological utensil of diagnosing a disease, and is used for the expansion cervix mouth.

During gynecological diagnosis and treatment, often need to expand the palace.All be to use one group of stainless steel rod both at home and abroad now, be called intra-uterine dilator, its diameter by φ 3.5mm to φ 10mm.Ascendingly during use probe into one by one, extract, until reaching the cervix uteri mouth size that treatment needs.The doctor is very nervous in the operation acts hurriedly in a messy situation, and the patient is very painful, and very easily scratch is bled, so that infects.The various countries expert constantly studies intra-uterine dilator tool economic, easy, health.

The purpose of this utility model provides a kind of palace of once just expanding and reaches and need size, and can not abrade the novel intra-uterine dilator of human body.

The purpose of this utility model is achieved in that the palace probe connects conduit to intra-uterine dilator and syringe is formed by expanding, key is that the expansion palace probe that it uses is to put one to expand the palace film outside the rustless steel tubule, expand the palace film and formed by elasticity parallel and nonelastic warp knitting, ectonexine is hung latex.

During use, will expand palace probe earlier and insert cervix uteri, and advance syringe then, and inject distilled water, distilled water enters the expansion palace film of overcoat through conduit and rustless steel tubule, makes and expands palace film lateral expansion, does not vertically increase.The expansion palace film of lateral expansion is enough to make cervix uteri muscular tissue to be expanded to the bore of needs, rapidly draws back liquid in the film with syringe again, and probe diameter restores, and can extract.The doctor can be as required, and decision advances a plurality of liquid.

The utility model has the advantages that: the patient does not have pain, and the doctor is simple to operate, and it is quick, satisfactory for result to expand the palace.

Details of the present utility model describes in detail by following examples:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 expands palace membrane structure figure.

With reference to the accompanying drawings 1, this utility model comprises and expands palace probe segment, duct portion and syringe part.It expands the palace probe segment is a stainless steel tube 2, diameter phi 3.5-4mm, the outside puts one and expands palace film 1, it is the net by elasticity parallel and nonelastic warp knitting, the inside and outside wall hanging emulsion layer of net, stainless steel tube 2 is inserted in conical surface joint 3 endoporus of conduit 5 one ends, is glued, the lower end of expanding palace film 1 then is enclosed within on the male cone (strobilus masculinus) of conical surface joint 3, compresses with hold-doun nut 4.The other end of conduit 5 is used with quadrat method and is fixed a stainless steel tube 7 and polyethylene conduit 8, and the other end of polyethylene conduit 8 connects syringe 9.10 for pushing away the liquid pipe.

With reference to the accompanying drawings 2, expand the palace film and form by the net 12 of inside and outside emulsion layer 11 and elasticity parallel and nonelastic warp knitting.

Through clinical trial, this utility model expands the palace at every turn only needed to finish in 30 seconds, generally advanced 3-5ml liquid can expand the palace mouth to φ 6-φ 10mm, and effect is very good.

Claims

1, the disposable intra-uterine dilator of gynecological, it comprises expands palace probe connecting duct and syringe, and the expansion palace probe that it is characterized in that it is that a rustless steel tubule overcoat expands the palace film, and this expansion palace film is formed by elasticity parallel and nonelastic warp knitting, inside and outside wall hanging emulsion layer.

2, intra-uterine dilator according to claim 1 is characterized in that said intra-uterine dilator tubule is bonded in the conical surface joint endoporus of conduit one end, expands the palace film and is pressed on the conical surface with nut.
