Abstract
The utility model provides a sucker for a gynecology department. The sucker for the gynecology department comprises an outer pipe. Sucking grooves which are communicated with an inner cavity of the outer pipe are formed in the top end of the outer pipe. The sucker for the gynecology department is characterized in that the sucking grooves are multiple in number, an inner pipe is connected inside the outer pipe in a sleeved mode, and cutting edges which correspond to the sucking grooves are arranged on the inner pipe. The sucker for the gynecology department is reasonable in design, simple in structure, convenient to use, and capable of removing blocking objects under the condition that a sucking pipe is not taken out, and thus the sucker for the gynecology department is capable of preventing a blocking phenomenon from happening in process of intrauterine suction.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically, relates to a kind of gynecological suction tube.
Background technology
Gynecological suction tube is department of obstetrics and gynecology a kind of medical apparatus and instruments commonly used, is used for stopping early pregnancy, can also be used under the multiple pathological changes situations such as endometrial hyperplasia, suspected tumor, infertility, cervical polyp for from uterus sucking-off thing in utero.General suction pipe is that a distolateral wall has strip attraction mouth, has or do not have top end opening, and the other end of suction pipe connects negative pressure source.The problem of this suction pipe is to attract mouth to be easy to by intrauterine film or other in utero thing obstruction, the medical worker has to repeatedly take out the operation that suction pipe is removed tamper in the attraction process, this has increased the uterine cavity internal contamination greatly, has caused the in utero chance of inflammation.
The utility model content
The purpose of this utility model is to overcome the weak point of above-mentioned conventional art, provides a kind of and can reduce obstruction, can not take out the gynecological suction tube that suction pipe can be removed tamper.
The purpose of this utility model reaches by following technical measures:
A kind of gynecological suction tube comprises outer tube, and the top of described outer tube has the attraction groove that is communicated with outer tube bore, it is characterized in that: described attraction groove is many, is socketed with interior pipe in the described outer tube, and described interior pipe is provided with and attracts the corresponding cutting edge of groove.Cutting edge has certain acutance, and is close to the inwall of outer tube.In use, the other end of interior pipe connects negative pressure source, normally suction pipe is equally operated, attract thing to stop up the situation that attracts groove in case endometrium etc. occurs, pipe in only needing to rotate, the cutting edge of interior pipe will downcut being blocked in the attraction thing that attracts in the groove, and goes out by interior bank of tubes, thereby removes the obstruction that attracts groove.
As a kind of improvement, the tail end of described outer tube is provided with locating slot, described in pipe be fixedly connected be positioned at locating slot, can be with respect to the locating piece of locating slot slip.The amplitude of relative slips between pipe and the outer tube in locating piece in locating slot can limit, pipe is by skidding off in the outer tube in preventing, and the cutting edge of pipe can excise from the tissue of attraction groove suction in making simultaneously.
As a kind of improvement, the top of described outer tube is provided with and attracts the hole, and the diameter in described attraction hole is less than the diameter of interior pipe.The diameter in attraction hole can guarantee that less than the diameter of interior pipe the object through attracting the hole to suck can go out by interior bank of tubes smoothly, and can not stop up interior pipe.
Owing to adopted technique scheme, compared with prior art, the utility model has the advantages that:
This utility model provides a kind of gynecological suction tube, have reasonable in design, simple in structure, easy to use, can under the situation of not taking out suction catheter, remove the advantage of tamper, so can prevent from stopping state occurring in the EA process.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of gynecological suction tube of this utility model;
Accompanying drawing 2 is cutaway views of a kind of gynecological suction tube of this utility model;
Accompanying drawing 3 be in the accompanying drawing 2 A-A to amplification view.
The specific embodiment
Embodiment: to shown in the accompanying drawing 3, a kind of gynecological suction tube comprises outer tube 3 as accompanying drawing 1, and the top of outer tube 3 has the attraction groove 2 that is communicated with outer tube 3 inner chambers, attracts groove 2 to be many, pipe 6 in being socketed with in the outer tube 3, and interior pipe 6 is provided with and attracts groove 2 corresponding cutting edges 7.Cutting edge 7 has certain acutance, and is close to the inwall of outer tube 3.In the present embodiment, attracting groove 2 is three.In use, the other end of interior pipe 6 connects negative pressure source, attract operation, attract thing to stop up the situation that attracts groove 2 in case endometrium etc. occurs, pipe 6 in only needing to rotate, the cutting edge 7 of interior pipe 6 will be blocked in the attraction thing that attracts in the groove 2 and downcut, and by interior pipe 6 discharges, thereby remove the obstruction that attracts groove 2.
As shown in Figures 1 and 2, the tail end of outer tube 3 is provided with locating slot 5, and interior pipe 6 is fixedly connected with the locating piece 4 that is positioned at locating slot 5, can slides with respect to locating slot 5.The amplitude of relative slips between pipe 6 and the outer tube 3 in locating piece 4 in locating slot 5 can limit, pipe 6 is managed 6 cutting edge 7 and can be excised from the tissue of attraction groove 2 suctions by skidding off in the outer tube 3 in preventing in making simultaneously.
To shown in the accompanying drawing 3, the top of outer tube 3 is provided with and attracts hole 1, attracts the diameter in hole 1 less than the diameter of interior pipe 6 as accompanying drawing 1.The diameter in attraction hole 1 can guarantee can discharge by interior pipe 6 smoothly through the object that attracts hole 1 to suck less than the diameter of interior pipe 6, and can not stop up interior pipe 6.
