Description
Technical field
This utility model belongs to technical field of medical equipment, especially relates to a kind of shooting 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, and cannot scalable be accomplished because of the focal length of COMS module in the structural design of apparatus, it becomes image focus to be preset in the outer surface edge of lens protection cover, during video capture, be equivalent to human eye against paper and look for word to become literate, without field range, be difficult to realize visual under operation technique.The problems such as in addition existing shooting 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 disposable visual decompression aspiration tube of induced abortion [application number: 201020292589.4], be made up of supervisor, relief pipe, handle and endoscope, the leading portion of supervisor is the top bending in circular arc, and the side at top has attraction window, and relief pipe is positioned at main pipe, both ends open is on the sidewall at supervisor back, relief pipe is not connected with supervisor, and endoscope stretches into main pipe, and its camera lens is fixed on the inwall at supervisor leading portion top.Such scheme to some extent solves the problem that when existing shooting suction catheter operates, accuracy is low, but the program still also exists: body mechanical strength is low, poor stability, and cost is high, the problem that focal length cannot adjust, field range is little.
