Description
Technical field
This utility model belongs to technical field of medical instruments, and specifically, the artificial abortion minimum particularly to a kind of blind area inhales
Skirt.
Background technology
Disposable visual artificial abortion's suction catheter is mainly used in visible abortion operation, and disposable visual artificial abortion's suction catheter is typically by head
The compositions such as cover, pipe shaft and handle, head-shield is fixed on the front end of pipe shaft, and this head-shield is usually cylindrical structure, utilizes the rear end of head-shield
Face carries out dilatation and curettage of uterine.During using, when head-shield pressed close to by pregnant capsule when head-shield conflict Uterus wall, there is the biggest dilatation and curettage of uterine blind
District, after thus running out visible induced abortion suction tube, in addition it is also necessary to uses and traditional disposably images suction catheter, in order to removes visual people
The position of operation do not accomplished by stream suction catheter, and such repetitive operation brings very big inconvenience to doctor, and can reduce the efficiency of operation.
Pipe shaft many employings high molecule plastic of disposable visual artificial abortion's suction catheter makes, it may be assumed that done by high molecule plastic pipe
Become many inner chambers form.The product that current pipe shaft makes two chambeies is in the majority, and attraction channel is made in a chamber, and another chamber is passing channel.By
In doing two-chamber passage at same pipe shaft, attraction channel so can be made to diminish, thus doctor can occur blocking existing in operation process
As.It addition, pipe shaft needs certain hardness, therefore, in order to ensure the rigidity of pipe shaft, it is necessary to made by pipe shaft wall thickness and be more than
More than 0.6mm, so can make passage become narrower and small, thus attract blocking risk.
Utility model content
Because the drawbacks described above of prior art, technical problem to be solved in the utility model is to provide a kind of blind area
Little artificial abortion's suction catheter.
Technical solutions of the utility model are as follows: artificial abortion's suction catheter that a kind of blind area is minimum, are provided with in the bottom of pipe shaft front end
Opening, the front end of pipe shaft is installed head-shield, is arranged photographic head in head-shield, it is characterised in that: it is provided with on the ring wall of described head-shield
The boss of dilatation and curettage of uterine effect.
Use above technical scheme, the ring wall of head-shield has arranged the boss of dilatation and curettage of uterine effect, by tradition at dilatation and curettage of uterine operation
The reach of head-shield rear end face, so effectively reduce the blind area in operation process, enabling the clinician to position accurately needs operation
Position, and use visual artificial abortion's suction catheter just can complete whole operation, doctor can more fully observe whole
Uterus inwall whether successful surgery, it is ensured that pregnant capsule is blotted only.
In order to simplify structure, realizing blind area as far as possible and minimize, described boss is integrally formed at the end of head-shield front end ring wall
Portion.
The bottom of described boss is arc-shaped flange, and the bottom of this boss is by the round and smooth mistake of front end face of arc surface with head-shield
Cross, and the distance between boss rear end face and head-shield front end face is less than 3.5mm.The front end of above structure head-shield, will not without wedge angle
Damaging human body, while guaranteeing that blind area minimizes, the structural strength of boss is reliable, is not susceptible to damage.
In order to simplify structure, further facilitate dilatation and curettage of uterine and pregnant capsule is sucked out, as preferably, the front end of described opening and pipe shaft
Mouth connection, the front port of pipe shaft is blocked by the rear end face of head-shield, makes opening form suction inlet；The convex of front end is removed bottom described head-shield
Outside platform, remainder is thin-walled planar.
As preferably, the rear end face of described head-shield is the arc top arc surface towards upper front.
Described pipe shaft is made up of medical stainless steel, and this pipe shaft is single inner-cavity structure, and the wall thickness of pipe shaft is less than 0.5mm.Pipe
Body makes medical stainless steel material, the most more robust more anticorrosive, and separates out entirely without metal ion, will not make patient
Become adverse effect；Meanwhile, medical stainless steel material pipe shaft inner chamber can be made to accomplish the limit is big, makes tract unimpeded, is so prevented effectively from
Doctor can occur the tract to block in operation process, enables the clinician to accurate positioning operation position.The wall thickness of pipe shaft is less than
0.5mm, so makes inner chamber big as far as possible thus rigidity toughness has both.
Operating for convenience, as preferably, the front end of described pipe shaft bends downwards, and the remainder of pipe shaft is straight section.
For the ease of processing and fabricating, and be conducive to introducing handle by wire harness from pipe shaft, the end face in the middle part of described pipe shaft
Have wire hole.
It is installed with Anti-rotary block at the rear portion of described pipe shaft.Above structure Anti-rotary block is easily assembled, the jail connected on pipe shaft
Good by property, Anti-rotary block and the adaptive groove phase clamping on handle, it is possible to prevent handle from rotating relative to pipe shaft, make handle at pipe
The good reliability installed with it.
The outline of described Anti-rotary block is " D " font.Above structure Anti-rotary block moulding is simple, it is easy to processing and fabricating, cost
Low, anti-rotation is effective.
The beneficial effects of the utility model are:
1) reducing dilatation and curettage of uterine blind area to the maximum limit, doctor can more accurately judge that the position needing operation, uses one
The visual artificial abortion's suction catheter of root just can complete whole operation, and procedure efficiency is high, and doctor can more fully observe whole uterus
Inwall whether successful surgery, it is ensured that pregnant capsule is blotted only.
2) use medical stainless steel to make the pipe shaft of the minimum artificial abortion's suction catheter in disposable blind area, on the one hand have rigidity concurrently
Toughness；On the other hand, in the case of same outer diameter size, its channel cross-section is maximum, utilizes space the most sufficient, is difficult to make
Become blocking in pipe, ensure that tract is unimpeded.
