Abstract
The invention provides a disposable vertebral balloon type cervical dilator comprising a deepened and extended main channel pipe, wherein a suction hole is formed in the drainage end of the deepened and extended main channel pipe; the deepened and extended main channel pipe comprises a water and gas injection channel, a local anesthesia drug channel and a straight operating channel; a water and gas injection sealing balloon injection outlet is formed in the top of the water and gas injection channel; the bottom of the water and gas injection channel is communicated with a water and gas injection inlet; a water and gas injection sealing balloon is arranged outside the water and gas injection sealing balloon injection outlet; a front end local anesthesia drug outlet is formed in the top of the local anesthesia drug channel and is located between the suction hole and the top of the water and gas injection sealing balloon; and a local anesthesia drug inlet is formed in the bottom of the local anesthesia drug channel. By using the disposable vertebral balloon type cervical dilator, the dilating process can be finished at one step in the local anesthesia drug administration process, the pain of a patient can be relieved, cervical laceration can be avoided, secretions can be sucked through negative-pressure suction while cervical dilating, and infection is not easily caused.
Description
Technical field
The present invention relates to cervical dilatation technical field, more specifically to one disposable vertebra shape bellows cervical dilator.
Background technology
Cervical dilator is that gynecilogical operation commonly uses apparatus, the cervical dilator of current Clinical practice is expansion metal rod, and point size varied in size expands palace successively, and when changing larger yardage uterine-expanding rod, patient pain is obvious, and such repeatable operation, cause the probability of nosocomial infection also can increase.Particularly hysteroscope operation is popularized, and requires cervix dilating about 10 ~ 10.5mm before hysteroscope operation, if cervix dilating failure, hysteroscope operation also just cannot complete smoothly.So in the urgent need to an a kind of persistence cervix dilating, and the cervical dilator of patient pain can be alleviated.
In existing clinical technology, Chinese patent CN2012202519743 discloses a kind of sacculus cervical dilator, it primarily of swelling gasbag and interlink therewith gas tube composition, inflatable interface is had in one end away from air bag of gas tube, this end is also connected with plug, this swelling gasbag is double-deck, and medial expansion air bag is positioned at lateral expansion air bag, and the swelling gasbag of gas tube and inner side interlinks.By injecting the mode of quantitative normal saline in gas tube, swelling gasbag is slowly strutted, thus make cervix uteri mouth spreading, because swelling gasbag is double-deck, strengthen balloon thickness, should not be clipped broken by operating forceps in use, but but there is following defect: one, need, by the hard such as vaginal dilator, operating forceps apparatus, dilator swelling gasbag is fed through cervix uteri mouth during operation, the damage of the tissues such as tract mucosa very easily occurs; Two, after expanding to swelling gasbag water filling, need to spin off plug, allow the water in capsule freely discharge, make to leave residual water in capsule, when extracting cervical dilator out, the residual water in capsule constantly can wade out and bring inconvenience; Particularly when accidentally expanding excessive by swelling gasbag when operating, do not shorten swelling gasbag into suitable expansion capacity by water extraction way; Three is unmarked references on gas tube, makes doctor be difficult to the pressure confirming to bear in swelling gasbag; Four is that swelling gasbag after expansion roundedly struts, and struts the pain of process aggravation patient.
Summary of the invention
Instant invention overcomes deficiency of the prior art, provide disposable vertebra shape bellows cervical dilator, disposablely can complete process of expansion, expand soft, prevent pain and cervix uteri from tearing the generation of phenomenon, can carry out vacuum suction while cervical dilatation carrys out sucking-off secretions simultaneously.
Object of the present invention is achieved by following technical proposals.
Disposable vertebra shape bellows cervical dilator, comprise deep prolongation main channel pipe, the described drain end deeply extending main channel pipe is provided with suction hole, the described main channel pipe that deeply extends comprises water filling gas injection passage, local anaesthesia drug channel, straight shape operating walk way, the top of described water filling gas injection passage is provided with water filling gas injection sealed bladder and injects outlet, bottom and the water filling gas injection inlet communication of described water filling gas injection passage are arranged, described water filling gas injection sealed bladder injects outside outlet and is provided with water filling gas injection sealed bladder, the width at the top of described water filling gas injection sealed bladder is less than the width of bottom, and the width of described water filling gas injection sealed bladder increases from top gradually to bottom, the top of described local anaesthesia drug channel is provided with described local anaesthetics front end exit, described local anaesthetics front end exit is between described suction hole and the top of described water filling gas injection sealed bladder, the bottom of described local anaesthesia drug channel is provided with local anaesthetics import, central supporting straight catheter core is inserted with in described straight shape operating walk way.
Described water filling gas injection passage, described local anaesthesia drug channel, described straight shape operating walk way are three separate and not through passages.
Described water filling gas injection passage fills normal saline or gas.
The shape of described water filling gas injection sealed bladder is taper.
Described water filling gas injection import department is provided with pressure display unit.
The end of described central supporting straight catheter core is provided with central supporting straight shape operation cap.
Described straight shape operating walk way is connected with vacuum extractor.
The quantity of described local anaesthesia medicine front end exit is 1 or 2.
Beneficial effect of the present invention is: water filling gas injection passage, local anaesthesia drug channel, straight shape operating walk way are separate, can complete the work of water filling gas injection, topical, insertion cervical dilator without interfering with each other; Straight shape operating walk way can insert central supporting straight catheter core, ensures the straight of channel during insertion; Extract central supporting straight catheter core, straight shape operating walk way pipe also can connect vacuum extractor, by suction hole, and sucking-off secretions; Water filling gas injection passage, by the mode of saline injection or inflation, makes that water filling gas injection sealed bladder is tapered slowly to be propped up from small to large, disposablely completes process of expansion, and it is soft to strut process, anti-pain relieving, prevents cervix uteri from tearing; Pressure display unit, can show gas injection pressure, can display scale; Local anaesthesia drug channel can carry out local to anaesthetic, local anaesthesia medicine front end exit is arranged between water filling gas injection sealed bladder and suction hole, can to realize in the process inserting cervical dilator and before propping up water filling gas injection sealed bladder to anaesthetic, prevent because of cervical dilator insert and the support of water filling gas injection sealed bladder time open the pain brought.The present invention disposablely can complete process of expansion, reduction of patient pain in the process of giving local anaesthetics, prevents cervix uteri from tearing, and can carry out vacuum suction while cervical dilatation and carry out sucking-off secretions, not easily infects.
