Abstract
The utility model relates to a disposable cervical dilator comprising a hollow pipe body. The hollow pipe body is provided with an air channel and a local anesthetic channel. The outlet end of the air channel is provided with an air bag. The purpose of dilating cervices can be achieved by the air bag dilatation which is injected with air through the air channel. At the same time of cervical dilatation, the anaesthetic is sent to the cervix. The utility model has the advantages of simple structure, no cross infection, no pain of patients during operation, and short dilation time. The utility model can also be used for urinary surgery, can take effect on dilating urethrostenosis caused by external injuries or other reasons, can be used for external auditory meatus and hemostasis for the nasal cavity by compression in otorhinolaryngology department, etc.
Description
This utility model relates to a kind of medical apparatus and instruments, particularly a kind of one-off cervix dilator.
At present, the domestic and international cervical dilator that in medical treatment, uses, for the stainless steel rod of different thicknesses is made, when clinical practice, begin to the discrepancy replacing back and forth one by one of thick stainless steel rod from thin stainless steel rod, to reach the purpose of cervix dilating, this dilator both had been inconvenient to use, and the expansion time is also longer, and owing to repeatedly use, cause that easily cross infection resembles AIDS, infusorian and other communicate illness.When operation, this kind dilator at first will arrive corresponding size to cervical dilatation at short notice, and because the influence of vagina length can not be given enough the local infiltration anesthesia medicine ideally, thereby the tractive in the operation can cause certain pain and spiritual fear to patient.
The purpose of this utility model is intended to overcome the shortcoming of above-mentioned prior art, propose a kind of one-off cervix dilator, when carrying out cervical dilatation, can send into anesthetics in time, when having cross infection simple in structure, no, operation, patient's pain, short characteristics of expansion time.
This utility model comprises a hollow pipe shaft, and an end of hollow pipe shaft has suction nozzle, and the cavity of suction nozzle and hollow pipe shaft communicates, the side configuration one stifled valve of suction nozzle; The other end of hollow pipe shaft is smooth hemispherical cecum, and the top of cecum has the venthole that communicates with cavity, and the position in the outside of hollow pipe shaft corresponding to venthole disposes air bag; Have the local anaesthetics passage on the tube wall of hollow pipe shaft, an end of local anaesthetics passage is positioned at an end of hollow pipe shaft for the local anaesthetics import, and the other end of local anaesthetics passage is the cecum that the local anaesthetics outlet is positioned at the hollow pipe shaft; Can be carved with on the hollow pipe shaft with the cecum is the graduation mark of starting point; Total can be by medical PVC, medical high polymer polyethylene from high pressure process or rubber single injection-molded.
Clinical use is that at first the smooth hemispherical cecum with hollow pipe shaft places cervical orifice, and with annotating barrel with the import of local anaesthesia medicinal liquid injection local anaesthetics, just by local anaesthetics passage and local anaesthetics outlet, notes are sprayed on the cervix uteri mouth local anaesthesia medicinal liquid; The limit enters limit spray local anaesthetics to the cervix uteri depths lentamente with the hollow pipe shaft then, treat that the hollow pipe shaft enters cervical canal after, inject air in certain amount with annotating the body device as required, make air bag full to reach the purpose of cervix dilating.In order to make the air bag after filling keep the sufficiently long time, can with stifled valve suction nozzle be blocked in the full back of air bag; Finish using, leave stifled valve, the air in the air bag is bled off, and then extract this utility model.The degree of depth that the hollow pipe shaft enters can be found out by the scale on it.
This shows that structure of the present utility model makes injection local anaesthetics and cervix dilating to carry out simultaneously, gallbladder has not been simplified operating performance, and has avoided prior art repeatedly to pass in and out the discomfort that causes to patient from fine to coarse; But, therefore can throw away after the use once, thereby avoid cross infection again owing to this utility model one-shot forming, cheap.
This utility model also can be used for Urology Surgery, carries out dilating effect for the urethral stricture that wound or other reason cause, and department of otorhinolaryngology is used for the hemostasis by compression of external auditory meatus, nasal bleeding etc.
Fig. 1 is an external structure of the present utility model.
Fig. 2 is a main cutaway view of the present utility model.
Fig. 3 is a vertical view of the present utility model.
Among the figure, (4) are the hollow pipe shafts, and (13) are the cavitys that runs through hollow pipe shaft (4), and (1) and (7) is respectively suction nozzle (1) and the venthole that is communicated with cavity (13); (2) be stifled valve, (3) are the stifled valve shifting blocks that connects stifled valve (2) and tube wall (12); (11) be the local anaesthetics passage that connects tube wall (12), (9), (10) are respectively local anaesthetics outlet and the local anaesthetics imports that communicates with local anaesthetics passage (11); Air bag (8) matches corresponding to the position of venthole (7) with hollow pipe shaft (4) by ring for fixing (6); Be carved with scale (5) on the hollow pipe shaft (4).
Most preferred embodiment:
Cavity (13) is straight pipe, and internal diameter is 2 millimeters; Tube wall (12) is thick to be 2～3 millimeters; Hollow pipe shaft (4) length is 21 millimeters, and far-end is smooth hemispherical cecum; Local anaesthetics passage (11) is straight pipe, and internal diameter is 0.5 millimeter, and straight-through cecum is with casting of medical PVC.
Claims (4)
1, one-off cervix dilator, comprise a hollow pipe shaft, feature of the present utility model is, one end of hollow pipe shaft has suction nozzle, the cavity of suction nozzle and hollow pipe shaft communicates, the other end of hollow pipe shaft is a cecum, the top of cecum has the venthole that communicates with cavity, position in the outside of hollow pipe shaft corresponding to venthole disposes air bag, have the local anaesthetics passage on hollow pipe shaft and the tube wall, one end of local anaesthetics passage is positioned at an end of hollow pipe shaft for the local anaesthetics import, and the other end of local anaesthetics passage is the cecum that the local anaesthetics outlet is positioned at the hollow pipe shaft.
2, dilator according to claim 1 is characterized in that, the side of said suction nozzle disposes the stifled valve supporting with it.
According to claim 1,2 described dilators, it is characterized in that 3, said cecum is a smooth hemispherical cecum.
