Description
Technical field
This utility model belongs to technical field of medical equipment, especially relates to a kind of medical visual suction catheter.
Background technology
Operate under the operation of existing abortion's dilatation and curettage of uterine mostly is ultrasonic surveillance, there is poor visual effect in art, directly perceived, location is inaccurate, operation wound is large, complicated operation, auxiliary facility are many, postoperative patient recovers slow and very easily cause because of shortcomings such as dilatation and curettage of uterine wound are large and sterile, surgical effect is mainly determined by patient's experience and skill.Current China is that abortion measures larger country, the research of external rare relevant like product.Domestic market is main or carry out dilatation and curettage of uterine artificial abortion based on ultrasonic surveillance, also have and utilize COMS module technology to carry out Related product research and clinic trial, although compared with conventional ultrasound, this series products monitors that the like product carrying out dilatation and curettage of uterine is had large improvement on Clinical practice, because some obvious design defect make it be difficult to popularize at clinical expansion.This is because camera part employing COMS module carries out structural design, because COMS module overall dimensions is larger, the rear of sheath pipe dilatation and curettage of uterine arc notch cannot be placed on, outer sheath can only be placed on foremost, action when then just can not observe dilatation and curettage of uterine when carrying out dilatation and curettage of uterine operation and surgery location and surgical effect.After finding pregnant capsule in operating process, first to leave pregnant capsule position on the contrary, carry out relocating sweeping according to the feel in departure process again, the situation specifically sweeping process has not just observed, this just makes to line-of-sight observation operative site in real time in operation process, be difficult to ensure surgical effect, accuracy is low.The problems such as in addition existing medical visual suction catheter also also exists: the mechanical strength of body is low, poor stability, and use cost is high.
In order to solve prior art Problems existing, people have carried out long-term exploration, propose solution miscellaneous.Such as, Chinese patent literature discloses a kind of postoperative examining endoscope for visible endoscopic abortion [application number: 201020536569.7], it single lumen catheter comprising an anterior bending or keep straight on, this single lumen catheter front end face is provided with the translucent cover that has high-transmission rate, to arranging a camera head by translucent cover summary retracted positions in described single lumen catheter.
Such scheme to some extent solves the little problem of existing medical visual suction catheter visual range, but the program still also exists: cannot open surgery position during operation, cannot operate while observation, surgical effect be poor, imaging effect is poor, the problem of poor stability.
Summary of the invention
