Technical field
The present invention relates to a kind of ultrasonic development conduit and moulding process, belong to technical field of medical instruments, can be used for the ultrasonic development technology of the soft conduits such as drainage catheter and interposing catheter.
Background technology
Based on minimally-invasive treatment have insufficiency of blood, postoperative pain light, recover fast, cicatrix is trickle or without the feature of cicatrix, is replacing gradually traditional operative treatment, its technology is also constantly being improved and development.Minimally-invasive treatment will coordinate electronigraph equipment to use together, by developing apparatuses such as ultrasonic, X ray or MRI, determine whether pipeline arrives focus, in known minimally-invasive treatment, there are the drainage catheter, the interposing catheter that adopt metal puncture needle and plastic cement system, because X-ray and CT have stronger radiation, general doctor is more prone to use localization by ultrasonic, but the video picture in ultrasonic of the drainage catheter of plastic cement system, interposing catheter is also not obvious, therefore, in Hospitals at Present, still generally adopt X ray and CT.In order to address the above problem, in industry, develop the drainage catheter that some can improve ultrasonoscopy, for example in drainage tube, add a large amount of inorganic fillers, the utility model patent B ultrasonic visual drainage catheter that is also CN201840755 just like publication number, clad metal line in duct wall.But above-mentioned drainage catheter processing technique is comparatively complicated, and adds after bonding jumper, how much all can be influential to the flexibility of conduit, be not easy to insert human body.And it is known, on metal puncture needle, due to shrinkage pool or erosion stricture of vagina can be set on needle body surface, therefore can by ultrasound wave, carry out video picture clearly, as the publication number patent of invention puncturing needle for ultrasound wave that is CN101227862 and the publication number patent of invention puncture needle that is CN101040790, but, in industry, also do not occur this kind of structure applications to soft drainage catheter and the technology on interposing catheter at present.
Summary of the invention
For addressing the above problem, inventor through studying intensively, has broken through technical difficulty, provide a kind of ultrasonic development conduit with and moulding process.
The present invention is that the technical scheme that its problem of solution adopts is:
A kind of ultrasonic development conduit, by ultrasound wave video picture, determine the position of conduit, comprise soft body 1, what described body can be crooked moves in human body, on the outer surface of described body, be provided with several reflection shrinkage pools 3, to form the reflecting surface of concentrating reflection supersonic wave.
Preferably, described several reflection shrinkage pools 3 are in axial direction uniformly distributed at body 1 outer surface, form line style reflector element a; Described several line style reflector elements a axle center around body on body 1 radial section interlocks or is uniformly distributed, and forms reflector space b.
Preferably, the cross section of described reflection shrinkage pool 3 is circular-arc.
Preferably, described reflection shrinkage pool 3 is triangle along the axial cross section of body, and the side near body outlet in this triangular-section is short brink.
A moulding process for ultrasonic development conduit, has some reflection shrinkage pools 3 at soft body 1 surface forming, and described several reflection shrinkage pools 3 are in axial direction uniformly distributed at body 1 outer surface, form line style reflector element a; Described several line style reflector elements a axle center around body on body 1 radial section interlocks or is uniformly distributed, and forms reflector space b.
Preferably, first molding body 1, then by compression mod post forming, reflect shrinkage pool 3 on body 1.
Preferably, described reflector space b is molded over one section independently on the second body 2, then that the second body 2 is bonding or link together with body 1.
Preferably, described reflector space b is molded over one section independently on the second body 2, then the second body 2 is sleeved on body 1.
The invention has the beneficial effects as follows: a kind of ultrasonic development conduit and moulding process are provided, make processing reflection shrinkage pool on soft body that possibility is provided, thereby can use ultrasonoscopy technology to position tracking to flexible pipe, avoid doctor patient to be subject to for a long time the adverse effect of X ray, and without add other material in body, simple in structure.

The specific embodiment
Ultrasonic development conduit of the present invention, can determine by ultrasound wave video picture the position of conduit.With reference to Fig. 1-Fig. 8, ultrasonic development conduit comprises soft body 1, and what described body 1 can be crooked moves in human body, is provided with several reflection shrinkage pools 3, to produce hyperacoustic concentrated reflecting surface on the outer surface of described body 1.Described several reflection shrinkage pools 3 are in axial direction uniformly distributed at body 1 outer surface, form line style reflector element a; Described several line style reflector elements a axle center around body on body 1 radial section interlocks or is uniformly distributed, and forms reflector space b.
Described reflector space b can pass through mould secondary machine-shaping, and the first embodiment that Fig. 1-Fig. 3 represents and the second embodiment representing as Fig. 4-Fig. 6 adopt secondary operations molding to obtain reflector space b.Certainly, reflector space b can also adopt the mode of split to be arranged on body 1, because catheter length is all long, therefore can be first by the reflector space b mould molding of needs processing reflection shrinkage pool 3, be the second body 2 independently, the mode that then adopts bonding (as shown in the 3rd embodiment in Fig. 7) or be socketed (as shown in the 4th embodiment in Fig. 8) is arranged on body 1.
Wherein, the cross section of described reflection shrinkage pool 3 can be set to circular-arc, as in the first embodiment shown, also can adopt other can the hyperacoustic shape of usable reflection, for example, shown in the second embodiment, being arranged to along the axial cross section of body 1 is triangle, and the side near body 1 outlet in this triangular-section is short brink, and its long side becomes the face of main reflection supersonic wave.
In addition, the present invention also provides a kind of moulding process of ultrasonic development conduit, at soft body 1 surface forming, has some reflection shrinkage pools 3, and described several reflection shrinkage pools 3 are in axial direction uniformly distributed at body 1 outer surface, form line style reflector element a; Described several line style reflector elements a axle center around body on body radial section interlocks or is uniformly distributed, and forms reflector space b.
Reflector space b can adopt following three kinds of methods to process.
Embodiment one, first molding body 1, then by compression mod post forming, reflect shrinkage pool 3 on body 1, molding effect is shown in the first embodiment and represented the second embodiment of Fig. 4-Fig. 6 that Fig. 1-Fig. 3 is represented.
Embodiment two, described reflector space b is molded over one section independently on body 2, and then body 2 and body 1 is bonding or link together, molding effect is shown in the 3rd embodiment that Fig. 7 is represented.
Embodiment three, described reflector space b is molded over one section independently on body 2, then body 2 is sleeved on body 1, and molding effect is shown in the 4th embodiment that Fig. 8 is represented.
Described in above description, be only principle of the present invention and embodiment, everyly according to essence of the present invention, carry out any simple modification and variation, within all belonging to protection domain of the presently claimed invention.
