Abstract
The utility model discloses a cervical dilator which comprises a dilator body arranged in a uterus, wherein the dilator body comprises a support frame body of an expanding and contracting structure and a supporting network surface covering the support frame body, and a medicine tectorial membrane layer is attached outside the supporting network surface. The cervical dilator has the advantages that the dilator comprises the support frame body of the expanding and contracting structure and the supporting network surface coated outside the support frame body, and the medicine tectorial membrane layer is attached outside the supporting network surface. The dilator has simple integral structure and is safe to use, the support frame body of the expanding and contracting structure is convenient to get in and out of the interior of a body, the expansion of the support frame body in the body can maintain the expansion of the uterus neck in space, and the network surface design outside the support frame body corresponds to the growth requirement of endometrium. Due to the adoption of the cervical dilator, the treatment can be carried out in an outpatient clinic, and the probing times of an uteroscope can be reduced during the treatment process, therefore, the medical expense is greatly reduced, and the obedience of the patient is improved.
Description
Technical field
This utility model relates to therapeutic device, especially relates to a kind of uterus uterine cavity cervical dilator that cervix uteri and intrauterine adhesion are used for the treatment of.
Background technology
The women is because repeatedly artificial abortion or in utero stimulation such as inflammation, and the sickness rate of uterus uterine cavity and cervical adhesion is more and more higher.Hysteroscope has advantages such as simple and direct, Wicresoft, determined curative effect during adhesion in treatment, but outbreak repeatedly easily after the exclusion under the adhesion hysteroscope at positions such as serious intrauterine adhesion or angle, palace, the treatment difficulty.Clinically after the adherence Separation,, can go into dissimilar intrauterine devices, and inject biological anti-blocking agent such as hyaluronate sodium at uterine cavity built-in according to the position of adhesion.In clinical practice, find, the angular position adhesion of every palace, very easily recurrence after the hysteroscope treatment is even it is also invalid in utero to insert various birth control apparatus.There is report to think that uterine cavity places birth control apparatus and use the curative effect less than 50% of 3 months artificial cycles to the severe intrauterine adhesion, may to be in closure state all the time relevant with these privileged sites of angle, palace.Behind the hysteroscope separation of synechia, all should use repeatedly and expand bar expansion uterine cavity.Because the expansion bar must arrive the minor operation room and operate, territory, old place and effective poor; ,, then easily stick together once again simultaneously as merging reproductive tract infection expanding palace, uterine cavity repeatedly gradually in the process of epithelization.Balloon expandable is adopted in present domestic clinical treatment adhesion more, though short run effect is remarkable, because must be to hospital's hospitalization, observation, effective poor, increased patient's medical expense, simultaneously because sacculus to the contention effect of uterus inner membrane of uterine cavity, also can suppress the growth of inner membrane of uterine cavity.
Summary of the invention
The purpose of this utility model is to provide a kind of uterus uterine cavity cervical dilator safe in utilization, evident in efficacy, and this dilator can be kept the expansion on the cervix uteri space, uterus, makes inner surface keep non-touching state, is beneficial to endometrial growth more.
For achieving the above object, this utility model can be taked following technical proposals:
Uterus described in the utility model uterine cavity cervical dilator, comprise and place intrauterine dilator body, described dilator body comprises the supporting frame of scalable structure, and is coated on the external support wire side of support frame as described above, is attached with medicine overlay film layer outside described support wire side.
Described supporting frame is the many piece brace rods of ring set on central shaft, and the upper end of described brace rod is connected mutually with the central shaft top, and the lower end is slidingly matched by movable part and described central shaft, and described central shaft is provided with positioner.
Described brace rod is by epimere and hypomere is hinged forms.
Described movable part is the moving casing that is sleeved on central shaft, and described keeper is for being fixed on the block on the described central shaft by spring.
Advantage of the present utility model is that dilator comprises the supporting frame of scalable structure and is coated on its outer support wire side, is attached with medicine overlay film layer outside supporting wire side; This dilator overall structure is simple, safe in utilization, the both convenient turnover of the supporting frame of scalable structure body interior, supporting frame expansion in vivo can make it keep expansion on the cervix uteri space, uterus again, and the outer wire side design of supporting frame meets the needs of endometrium growth.This kind treatment outpatient service can be carried out, and can reduce the number of times of detecting of hysteroscope during treating, and greatly reduces medical expense, has improved patient's compliance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the sketch map of Fig. 1 swelling state.
The specific embodiment
As shown in Figure 1, 2, uterus described in the utility model uterine cavity cervical dilator, comprise and place intrauterine dilator body, described dilator body comprises the supporting frame of scalable structure, and be coated on the external support wire side 1 of support frame as described above, outside described support wire side 1, be attached with medicine overlay film layer 2.
For guarantee dilator when opening and the uterocervical shape of human body adapt, described supporting frame be ring set on central shaft 3 by epimere 4 and hypomere 5 hinged many brace rods that form, the upper end of described brace rod is connected mutually with central shaft 3 tops, the lower end is slidingly matched by movable part and described central shaft 3, and described central shaft 3 is provided with positioner.For making it simple in structure, above-mentioned movable part is the moving casing 6 that is sleeved on the central shaft 3, and described keeper is for being fixed on the block 7 on the described central shaft 3 by spring.Before not entering human body, dilator integral body is bar-shaped, be convenient to enter human body, after entering in the body, moving casing 6 is upwards pushed away along central shaft 3, (epimere is shorter by two sections owing to brace rod, hypomere is longer) hinged forming, configuration after making dilator expand (going up garden point down) more meets the normal condition in human body uterus, so can open to suitable degree in vivo according to the concrete shape control brace rod of individual uterine cavity when using, the support wire side and the applying degree between cervix uteri and the uterine cavity that guarantee dilator reach best, then by the locating piece on the central shaft 37 location, like this can be in the expansion of keeping during the whole treatment on the cervix uteri uterine cavity space, uterus, make its inner surface keep a kind of mutually between discontiguous state, be beneficial to endometrial growth, reach the purpose of radical cure uterus cervix uteri and intrauterine adhesion.After treatment finishes, push locating piece 7, moving casing 6 is moved down along central shaft, whole dilator retracts into bar-shaped, conveniently takes out in human body.
