Description
Technical field
The present invention relates to cervical dilatation technical fields, more specifically to a kind of disposable vertebra shape bellows cervical dilatation
Device.
Background technique
Cervical dilator is that gynecological surgery often uses instrument, and the cervical dilator of clinical use is expansion metal stick at present, point
Size of different sizes successively expands palace, and when replacing bigger yardage rod for expanding cervix, patient pain is obvious, and operates repeatedly in this way, draws
The probability for playing hospital-acquired infection also will increase.Especially hysteroscope operation is universal, and cervix dilating about 10 is required before hysteroscope operation
~10.5mm, if cervix dilating fails, hysteroscope operation is also just unable to complete successfully.So there is an urgent need to a kind of primary lasting
Property cervix dilating, and the cervical dilator of patient pain can be mitigated.
In existing clinical technology, Chinese patent CN2012202519743 discloses a kind of sacculus cervical dilator, it leads
It to be made of swelling gasbag and the gas tube to interlink with this, have inflatable interface in one end of the separate air bag of gas tube, the end
Be also connected with plug, which is bilayer, and medial expansion air bag is located in lateral expansion air bag, gas tube and inside it is swollen
Flatulence capsule interlinks.By way of injecting quantitative physiological saline into gas tube, swelling gasbag is slowly strutted, to make palace
Neck mouth spreading strengthens balloon thickness, should not be clipped broken when in use by surgical clamp, but deposit since swelling gasbag is bilayer
In following defect: needing to be fed through expander swelling gasbag by the hard such as vaginal dilator, surgical clamp instrument when one, performing the operation
Cervix opening, the easily damage of the tissues such as generation cavity mucous membrane；Two, it after being expanded to swelling gasbag water filling, needs to spin off plug,
It allows the water in capsule to be freely discharged, makes in capsule that there are residual water, when extracting cervical dilator out, the residual water in capsule can be waded out constantly
It brings inconvenience；It, cannot be by water extraction way by swelling gasbag especially when swelling gasbag expanded excessive accidentally in operation
Shorten suitable expansion capacity into；Third is that unmarked reference on gas tube, makes doctor be difficult to confirm the pressure born in swelling gasbag
Power；Fourth is that expansion after swelling gasbag it is rounded strut, strut process aggravation patient pain.
Summary of the invention
The present invention overcomes deficiencies in the prior art, provide disposable vertebra shape bellows cervical dilator, can be primary
Property complete process of expansion, expand soft, prevent pain and uterine neck from tearing the generation of phenomenon, at the same can while cervical dilatation into
Secretion is sucked out in row vacuum suction.
The purpose of the present invention is achieved by following technical proposals.
Disposable vertebra shape bellows cervical dilator, including deep extension main channel pipe, it is described deeply to extend main channel pipe
It drains end and is equipped with suction hole, the deeply extension main channel pipe leads to including water filling gas injection channel, local anaesthesia drug channel, straight operation
Road, it is described water filling gas injection channel top be equipped with water filling gas injection sealed bladder injection outlet, it is described water filling gas injection channel bottom with
The setting of gas injection inlet communication is filled the water, water filling gas injection sealed bladder injection outlet is externally provided with water filling gas injection sealed bladder, the water filling
The width at the top of gas injection sealed bladder be less than bottom width, and it is described water filling gas injection sealed bladder width from top to bottom by
Cumulative big, the top of the local anaesthesia drug channel is equipped with the local anaesthetics front end exit, and the local anaesthetics front end exit is located at institute
It states between suction hole and the top of the water filling gas injection sealed bladder, the bottom of the local anaesthesia drug channel is equipped with local anaesthetics import,
Central supporting straight catheter core is inserted in the straight operating walk way.
The water filling gas injection channel, the local anaesthesia drug channel, the straight operating walk way are mutually indepedent and do not penetrate through
Three channels.
The water filling gas injection channel filling physiological saline or gas.
The shape of the water filling gas injection sealed bladder is taper.
The water filling gas injection entrance is equipped with pressure display unit.
The end of the central supporting straight catheter core is equipped with central supporting straight and operates cap.
The straight operating walk way is connect with vacuum extractor.
The quantity of the local anaesthesia drug front end exit is 1 or 2.
The invention has the benefit that water filling gas injection channel, local anaesthesia drug channel, straight operating walk way are mutually indepedent, it can
Water filling gas injection, local administration, the work for being inserted into cervical dilator are completed without interfering with each other；Straight operating walk way can be inserted into central branches
Straight catheter core is supportted, guarantees the straight of tube channel during insertion；Extract central supporting straight catheter core, straight operating walk way
Pipe can also connect vacuum extractor, and by suction hole, secretion is sucked out；Water filling gas injection channel is by saline injection or fills
The mode of gas, making water filling, gas injection sealed bladder is tapered slowly props up from small to large, disposably completes process of expansion, and strut process
Soft, anti-analgesic prevents uterine neck from tearing；Pressure display unit can show gas injection pressure, can show scale；Local anaesthesia drug channel
Part can be carried out to anaesthetic, local anaesthesia drug front end exit is set between water filling gas injection sealed bladder and suction hole, it can be achieved that inserting
During entering cervical dilator and water filling gas injection sealed bladder is propped up before to anaesthetic, prevents from being inserted into and infusing because of cervical dilator
Water gas injection sealed bladder opens bring pain when supportting.The present invention can disposably complete process of expansion during to local anaesthetics,
Reduction of patient pain, prevents uterine neck from tearing, and can carry out vacuum suction while cervical dilatation secretion is sucked out, and is not easy to send out
Raw infection.
