Description
Technical field
The invention belongs to technical field of medical instruments, specifically, particularly a kind of doctor of allowing more clearly can observe the disposable visual artificial abortion suction catheter of patient in operation process by front end photographic head.
Background technology
Existing painless visible abortion is mainly divided into ultrasonic visible Therapeutic Abortion and hysteroscope visible abortion art, but two kinds of technology all need anaesthetize patient in advance and expand palace, can cause certain injury to the healthy of patient.Chinese patent 201210404408.6 discloses a kind of Microspur visual endoscopic device on February 13rd, 2013, this device by interiorly peeping pipe, handle, FPC circuit board, translucent cover, the first-class parts of attraction form, translucent cover front end closed rear end is uncovered, this translucent cover is connected with interior pipe of peeping by adaptor, and existing deficiency is:
1, parts are more, and production cost is high, complex operation during assembling and easily makeing mistakes, and not only efficiency of assembling is lower, and can reduce production qualification rate.
2, look straight ahead and backsight cannot complete simultaneously, be difficult to accurate location, be unfavorable for that doctor observes and operates in operation process.
3, peeping pipe in is double cavity structure, and a tract wears FPC circuit board, and another tract, for attracting chamber, can cause thus and attract tract narrow and small, easily cause tract to block.
Summary of the invention
Because the above-mentioned defect of prior art, technical problem to be solved by this invention is to provide a kind of can simultaneously direct-view straight and the disposable visual artificial abortion suction catheter of backsight observation.
Technical solution of the present invention is as follows: a kind of can look at straight simultaneously and backsight observation disposable visual artificial abortion suction catheter, comprise front bottom end to be provided with in suction port (11) and to peep pipe (1), translucent cover (2), FPC circuit board (3) and the photographic head (4) be connected with FPC circuit board (3), its key is: described photographic head (4) is positioned at the upper cavity (21) arranged of translucent cover (2), the ante-chamber wall of described cavity (21) is made up of the direct-view guide surface (23) on top and the backsight guide surface (24) of bottom, backsight guide surface (24) is provided with reflecting coating, described photographic head (4) can be taken the front of translucent cover (2) by direct-view guide surface (23), photographic head (4) can be taken the back lower place of translucent cover (2) by the reflecting coating on backsight guide surface (24).
Adopt above technical scheme, the direct-view guide surface of translucent cover cavity ante-chamber wall plays perspective, photographic head is enable directly to take the front of translucent cover, reflecting coating on translucent cover cavity ante-chamber wall backsight guide surface plays refraction, photographic head is enable to take the back lower place of translucent cover by reflecting coating, like this in operation process, direct-view and backsight observation can be completed simultaneously, following technique effect can be brought to doctor:
The effect observing rear precise positioning is played in a, direct-view;
B, direct-view can make doctor blindly operate;
The misery of patient can be avoided or reduce to c, good later the performing an operation of direct-view observation;
Whether the pregnant capsule that the operation of d, backsight Observable is attracted in carrying out is dynamic, or observe pregnant capsule be attracted completely;
As can be seen here, direct-view and backsight are observed simultaneously, can realize above-mentioned a, b, c, d tetra-technique effects simultaneously, are conducive to doctor and perform an operation and observe, effectively reduce surgical operation difficulty.
Described translucent cover (2) is arranged the uncovered cavity in upper end (21), photographic head (4) loads in the cavity (21) of translucent cover (2) from top to bottom, and upper end and the interior top of managing (1) front end of peeping of translucent cover (2) fix.Photographic head loads in the uncovered cavity in translucent cover upper end by above structure, and translucent cover is directly fixed with interior pipe of peeping, effectively reduce amount of parts like this, reduce production cost, and enormously simplify assembly technology, make assembly operation simple, convenient, while raising efficiency of assembling, effectively can prevent the phenomenon generation that makes mistakes, thus improve production qualification rate.
Be symmetrically arranged with guiding rib (41) in the left and right sides of described photographic head (4), this guiding rib (41) slips in the interior corresponding chute (22) arranged of cavity (21) of translucent cover (2) from top to bottom.Photographic head is matched with the chute on translucent cover by the guiding rib of the left and right sides, being easy to para-position, making assembly manipulation easier, quick when assembling; After being seated, photographic head is by guiding rib and the clamping of translucent cover phase, and photographic head can not loosen, and the steadiness of installation is good.
The lateral surface of described guiding rib (41) lower end is arc surface, and this arc surface plays guiding when assembling, and arc surface can reduce the frictional resistance between translucent cover chute, further increases the convenience of assembling.
The end face of described cavity (21) left right chamber wall and the end face of back cavity wall are arc surface, the end face of cavity (21) left right chamber wall all fits with the interior inwall of managing (1) front end of peeping, end face and the FPC circuit board of cavity (21) back cavity wall are fitted, upper end and the interior front end face of managing (1) of peeping of described cavity (21) ante-chamber wall are fitted, translucent cover (2) and interior peep to manage between (1) fixed by viscose glue.Above structure translucent cover and interior to peep contact point between pipe many on the one hand, contact area is large, can guarantee the fastness that translucent cover is installed; On the other hand, the upper port of translucent cover cavity is by the interior inner wall sealing peeping pipe front end, and good airproof performance, can effectively prevent liquid from entering translucent cover cavity.
Described direct-view guide surface (23) is low early and high after inclined-plane, backsight guide surface (24) is inclined-plane low after front height, looks at the center of connecting place lower than described photographic head (4) of guide surface (23) and backsight guide surface (24) straight.Above Mechanical Builds is simple, is easy to processing and fabricating, can reduces production cost further, and can guarantee the effect of direct-view and backsight.
In order to make structure compacter, and increase the visual field of direct-view and backsight as far as possible, the inner bottom surface of described cavity (21) is low early and high after step surface, there is the frontal plane and back plane that are parallel to each other, there is between described direct-view guide surface (23) and the frontal plane of cavity (21) inner bottom surface the angle of 53-73 °, there is between described backsight guide surface (24) and the frontal plane of cavity (21) inner bottom surface the angle of 107-127 °.
Peep pipe (1) in described for straight pipe, wear FPC circuit board (3) interior peeping in pipe (1).The endoporus inside peeping pipe is single tract, and this tract, as attraction tract, under peeping the prerequisite of pipe external diameter, attracts tract enough large, can not block in not expanding.
The invention has the beneficial effects as follows:
1, parts are few, and production cost is low, and assembly manipulation is simple, convenient, and packaging efficiency is high, and production qualification rate is high.
2, can carry out looking at straight and backsight observation simultaneously, be conducive to accurate location, doctor can be performed an operation and observe, while reduction surgical operation difficulty, can avoid or reduce patient suffering.
3, attract tract large, effectively can avoid blocking.
