Abstract
A uterine-dilatated rod is applied on uterine dilatation surgery of gynaecology and obstetrics. The device belongs to the medical apparatus and instrument. The utility model comprises a rod and a uterine-dilatated head that is arranged at the end of the rod and set at a certain angle of alpha with the rod. The advantages are listed as follows. First, the uterine-dilatated head is changed to a cone shape in comparison with a column shape in prior art. The new structure enables the rod to access to the uterus gradually, so that it does not need to change a new one on the same surgery. In this way, it would save surgical time and relieve patient's panic. Second, the apparatus is made up of medical high polymer material rather than stainless steel. The new material is of good flexibility, thus it won't hurt the uterus. And the cheap material is disposable, which can protect the rod from infection. Third, medical personal can hold the rod firmly because of the thread on it. Fourth, the rod's angle fits with the one in the uterus, which makes the uterine-dilatated head get through the uterine cavity easily. Fifth, the scale in the rod enables the medical personnel to command the depth of the rod getting through the uterine cavity.
Description
Technical field
This utility model relates to a kind of uterine-expanding rod, is used for the cervical dilatation of department of obstetrics and gynecology uterine cavity drawing operation, belongs to medical apparatus and instruments.
Background technology
Uterine-expanding rod is to be used for the operating theater instruments of cervix dilating, and the use in the department of obstetrics and gynecology uterine cavity drawing operation is of long duration.So far, employed one group of uterine-expanding rod is generally 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm in the related complete operation of artificial abortion operation because of accidental pregnancy need be done to the women, or the like, every 0.5mm is a level number.As seen, if will finish the operation receiveing person and expand the palace, often need one group or claim a cover specification as the aforementioned by little to big uterine-expanding rod, so in whole surgery, must change rod again and again, not only can cause the prolongation of operating time, and can increase operation receiveing person's misery, even because the uterine-expanding rod quantity of using is many, the just corresponding height of the probability that uterine cavity is infected, the risk factor that human body constituted injury are big.
China Patent No. ZL92209941.3 has introduced and a kind of has used novel uterine-expanding rod more, and it can expand 20mm to from 4mm, and alternative more than 30 uterine-expanding rod that is to say that the operation receiveing person only need use once, need not frequently to change in operation process rod.The disclosed intra-uterine dilator structure of Chinese patent CN2659480Y is utilized strutting of umbrella and is drawn principle in the operation receiveing person is expanded the palace, and it is tired to avoid frequently changing in the art rod equally.
The disclosed intra-uterine dilator of above-mentioned document all can not show gradual expansion palace, and operation receiveing person's distress level is big; If fruit is that disposable use then can be protected from infection, but use cost is bigger, and from the complexity of its structure as can be known, this intra-uterine dilator carries out disinfection after usefulness and uses repeatedly.Perhaps in view of this factor, do not see that in medical institutions the intra-uterine dilator that the disclosed version of above-mentioned document is arranged or the intra-uterine dilator of other similar type use.But still continue to use traditional by structure shown in Figure 2 and material be stainless uterine-expanding rod.This uterine-expanding rod comprise cylindrical barred body 1 and be arranged on integratedly barred body 1 end and and barred body 1 between constitute the cylindrical uterine-expanding head 2 of being similarly of an angle [alpha].Mainly there is following shortcoming in the uterine-expanding rod of this structure: the one: because uterine-expanding head 11 is isodiametric, therefore in operation process, must frequently change rod, for example in the time will expanding to 6.5mm from 4.5mm cervix uteri, need to change rod so 6 times, if and when expanding to 7.5mm from 4mm with varying with each individual, then need to change the uterine-expanding rod of 8 corresponding specifications, not only cause the prolongation of operating time, and can increase surgery cost and operation receiveing person's misery; The 2nd, be rustless steel because material adopts, thereby pliability extremely is short of, operative doctor must be operated double cautiously, otherwise can cause the injury of tearing property to cervix uteri; The 3rd, because the uterine-expanding rod price of stainless steel is higher, medical institutions consider from the equipment cost factor, often at operation receiveing person's postoperative uterine-expanding rod are carried out disinfection, and are standby.Therefore sterilization must be very strict, however, still is no lack of the report that has postoperative to suffer cross infection and nosocomial infection.
Summary of the invention
Task of the present utility model is to provide a kind of need not frequently to change rod in operation process and can save operating time, alleviate the uterine-expanding rod of operation receiveing person's pain.
An also task of the present utility model be to provide a kind of have well flexible, can not cause the injury of tearing property and can stop the uterine-expanding rod of cross infection and nosocomial infection to cervix uteri.
A task more of the present utility model is to provide a kind of holding to pinch reliable uterine-expanding rod.
Another task of the present utility model is that a kind of uterine-expanding rod that can successfully enter in the uterine cavity will be provided.
More of the present utility model and task is to provide a kind of being beneficial to grasp the uterine-expanding rod that enters into the uterine cavity degree of depth.
For top priority of the present utility model is finished in embodiment, technical scheme provided by the utility model is: a kind of uterine-expanding rod, comprise barred body 1 and be arranged on integratedly barred body 1 terminal part and and barred body 1 between constitute the uterine-expanding head 2 of an angle [alpha], described uterine-expanding head 2 be shaped as cone.
For an also task is finished in embodiment, technical scheme provided by the utility model is: the material of described barred body 1 and described uterine-expanding head 2 is medical macromolecular materials, and medical macromolecular materials are any one in polyethylene, polypropylene, polrvinyl chloride, politef, nylon, silicone rubber, the polyurethane.
For finishing a task again, technical scheme provided by the utility model is: the top ends at described barred body 1 is provided with screw thread 11.
For finishing another task, technical scheme provided by the utility model is: described is that angle [alpha] is 160-172 °.
For finishing a more task, technical scheme provided by the utility model is: described barred body 1 is provided with scale mark 12.
Preferably, the length of described barred body 1 is 10-14cm, and diameter is 6-7mm.
Preferably, the length of described uterine-expanding head 2 is 3-5cm, and the diameter of uterine-expanding head 2 is the 6.5-7.5mm to base portion 22 from the 4-5.5mm of front end 21 flaring.
Preferably, described angle [alpha] is 165-170 °.
Preferably, the length of described barred body 1 is 12cm.
Preferably, the length of described uterine-expanding head 2 is 4cm.
One of advantage of the present utility model becomes cone with the structure of uterine-expanding head 2 by the equal diameter cylinder in the prior art, can expand the palace with progressive form, need not to change rod in same operation process, both can save operating time, can alleviate operation receiveing person's misery again; Two, become the material rustless steel and be medical macromolecular materials, have good pliability, can not damage, and can embody disposable use because of cheap to cervix uteri, can stop to infect; Three, the screw thread on the barred body 1 help the medical worker hold pinch reliable; Four, the design of angle [alpha] and human body cervix uteri angle adapt, and can make uterine-expanding head 2 enter uterine cavity smoothly; Five, scale mark 12 is set on barred body 1 medical worker is supportted hold the degree that uterine-expanding head 2 enters uterine cavity.
