Description
Technical field
The present invention relates to a kind of gynecological and detect apparatus, especially a kind of visual interstitial catheter type surgical instrument that is used for uterine cavity and tubal assessment belongs to medical mechanical domain.
Background technology
The uterus is women's important genitals, also is the multiple position that very easily produces gynecological's pathological changes among the women crowd.Uterus carcinoma, cervical cancer, ovarian cancer and salpingitis tubal etc. have become the main killer of harm female body health and even life safety.In family planning work, antiearly pregnancy and unscheduled pregnancy have become an importance of family planning work simultaneously.The physiological status that the above-mentioned operation of early discovery needs, higher for the success rate of curing above-mentioned gynaecopathia, the effect of handling early pregnancy is also more satisfactory.In present conventional gynecologial examination and the operation, normal adopt B ultrasonic, cavity mirror, peritoneoscope or other imaging systems to observe art before, the state and the effect of postoperative, but these equipment all exist complex operation, operating theater instruments caliber thick excessively (generally between 10～26mm), easily cause patient's pain, and be not various problems such as disposable use.
Therefore, in carrying out the detection of cervix uteri purpose, must expand palace or the operation of swollen palace, even take above-mentioned measure still can not enter fallopian tube with detecting apparatus.Existing above-mentioned checkout equipment of while still exists can not be at the external diseased region of determining intuitively in intrauterine cavity or the defeated ovum.In addition, owing to exist intersection to use the phenomenon of apparatus, be difficult to the possibility of avoiding cross infection to produce.
Just because of above-mentioned reason, add the special construction in women uterus, can't implement directly shooting and shadowgraph technique and position.Have only and use other comparatively complicated auxiliary operation means just can finish the in utero ideal inspection of state, thereby cause having some gynecological's pathological changes often in time not found, delay the best opportunity of treatment.
In order to address the above problem, the inventor has once proposed denomination of invention to State Intellectual Property Office respectively at 2004 and 2006 and has been " uterine cavity tissue suction catheter " (patent No. is: ZL200420019500.1 and ZL200620044836.2), have the body of certain camber and constitute the suction catheter that can absorb uterine cavity inner tissue liquid by a head, carry out pathology detection so that obtain intrauterine tissue fluid at the attraction mouth of offering near the distolateral wall of body.Thereafter the inventor proposed denomination of invention to State Intellectual Property Office on 11st in JIUYUE in 2007 again (patent No. has been: ZL200720074546.7) for " disposable uterine cavity and vaginal probe ", the pathologic finding that hope not only can be convenient to carry out tissue fluid with intrauterine tissue fluid sucking-off by the suction inlet of suction catheter head setting, wish again simultaneously can by be located in the tube chamber weak point must not miniature probe can configuration state display screen together of following time with the uterine cavity inwall on, the doctor more can be diagnosed intuitively.
In November, 2008 inventor submitted again that application number is 200820154846.0 to, denomination of invention is a kind of apparatus that the defeated ovum of women is detected usefulness that is exclusively used in of " interstitial catheter ", attempt solves does not have the tubal assessment apparatus that expands under palace or the operation of swollen palace.
Above-mentioned numerous technical scheme can not reach perfect condition in clinic trial; its chief reason is: when carrying out the tissue fluid absorption; because the caliber of suction catheter is more tiny; in case tissue fluid denseer thick or when in the liquid of being drawn, also having blood regular meeting the passage of suction pipe is stopped up, therefore can't realize the attraction of tissue fluid at all and carry out other detections.And maximum problem is truth and the accurate position that can't grasp fallopian tube position inflammatory conditions clinically all the time intuitively, makes diagnosis still be in deduction phase.
Therefore, how apparatus being detected in existing women uterus further improves, determine intrauterine cavity and fallopian tube diseased region timely and accurately and the shooting radiography in affected part is provided for the doctor, both alleviated patient's misery, also just become the problem of needing solution in gynecological's detection badly for treatment provides even more ideal foundation.
