The accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Fig. 2 is the A-A cross-sectional view of the embodiment of the present invention while being arranged on blood vessel.
The specific embodiment
Shown in Fig. 1-2, a kind of not damaged device of blocking out blood flow, comprise vascular forceps clamp road 1, described pipeline comprises upper wall 1-1 and lower wall 1-2, upper wall 1-1 and lower wall 1-2 are flexibly connected by suitable draw-in groove and snap close, the inwall of described upper wall 1-1 is provided with air bag 1-3, and it can be also the air bag of having inflated that the inwall of described lower wall 1-2 is provided with elastomeric material 1-4(); Also comprise for controlling the air flow controller of air bag hollow tolerance, described air flow controller comprises aerating device 2, breather 3 and is arranged on the gas flow controller 4 on breather 3, described aerating device 2 can be also hand air pump for the syringe 2-1(with pushing hands 2-1), pushing hands 2-1 and syringe 2-1 are metal material, described breather 3 is resistant to elevated temperatures rubber tube 3-1, the pliers that described gas flow controller 4 is clip 4-1(or belt lock catch), described breather 3 is communicated with the air bag 1-3 of upper wall 1-1 inwall.
Wherein, described vascular forceps clamp road 1 is the internal diameter hollow pipe that is the metal material that do not wait of a series of diameters of 0.5cm, 1.0cm, 1.5cm or 2cm (selecting to be slightly larger than the pipeline 1 of internal diameter of the diameter of blood vessel according to the diameter of blood vessel), two walls up and down of pipeline 1 have respectively two suitable draw-in grooves and snap close to control the closure of pipeline at the two ends of pipeline 1, and tightly wrap up by resistant to elevated temperatures elastomeric material at the two ends of pipeline 1 (two ends of upper wall 1-1 and lower wall 1-2), prevents injured blood vessel and tissue.Described rubber tube is the silica gel material, and length is 18-22cm, and diameter is 0.3-0.6cm, and preferred, length is 20cm, and diameter is 0.5cm.Rubber tube 3-1 can be communicated with air bag 1-3 from the opening part of pipeline 1; Also can on the upper wall 1-1 of pipeline 1, be provided with through hole 1-5, rubber tube 3-1 is communicated with air bag 1-3 through through hole 1-5.Described rubber tube 3-1 top is provided with interface 3-2, and the interface 3-2 that the outlet of aerating device 2 is connected to rubber tube 3-1 top is inflated.The part of air bag 1-3 embeds upper wall 1-1 inwall uniformly; Elastomeric material 1-4 embeds the lower wall 1-2 inwall of pipeline 1 uniformly, keeps flexibility and the toughness of lower wall 1-2.Described draw-in groove and snap close are flexible, resistant to elevated temperatures metal, as wolfram steel CD650 Kennametal.
In surgical operation, when this apparatus is used for the not damaged bloodstream blocking or exposes near the surgical field of view of blood vessel, vascular forceps clamp road 1 is opened, by pipeline lower wall 1-2 gently put into blood vessel 8 below, closed draw-in groove and the snap close at closed duct 1 two ends, stably inserted blood vessel 8 in vascular forceps clamp road 1.
When for operation, the blood vessel of some organ being carried out to provisional not damaged blocking-up, only need the operation air flow controller, by aerating device 2, in air bag 1-3, inflate, the syringe outlet is connected on the interface 3-2 of rubber tube 3-1, push away gas by pushing hands in syringe, rubber air pump (also cry and the blow up a balloon) inflation that also can pinch with hands.Pressure by air bag 1-3 in vascular forceps clamp road 1 forces blood vessel 8 obliteration, and blood flow stops; Work as EO, while needing open blood flow, at first open gas flow controller 4, the gas in release air bag 1-3, and then open draw-in groove and the snap close in vascular forceps clamp road 1, take out the pipeline lower wall 1-2 below blood vessel 8 smoothly, leaves surgical field of view.
When for not damaged tractive blood vessel, while exposing surgical field of view, only need slightly affect gas flow controller 4(handled easily, can handle be set at gas flow controller 4, perhaps with being with handled clip or pliers as gas flow controller 4), by rubber tube 3-1, pulling force is delivered to vascular forceps clamp road 1, and then not damaged arbitrarily affects the blood vessel that hinders surgical field of view; Work as EO, while needing to recover vessel position, need carefully to open draw-in groove and the snap close in vascular forceps clamp road 1, smoothly blood vessel 8 following pipeline lower wall 1-2 are taken out, leave surgical field of view.
When the provisional blocking-up of blood flow of blood vessel, the pressure by this instrumentation gas forces that vessel lumen is closed, bloodstream blocking; When blood flow is open, by discharging gas, eliminates gas pressure and vessel lumen is opened.Thereby, the blocking-up of blood flow and open depend on the gas pressure in air bag, and then whole operation do not cause damage to the inner and outer wall of blood vessel, belongs to a kind of bloodstream blocking of non-invasi.
At the tractive blood vessel, while exposing near surgical field of view blood vessel, blood vessel 8 is stable in vascular forceps clamp road 1.Two walls up and down of pipeline 1 have all embedded pliable and tough rubber layer (or air bag), and the two ends of pipeline 1 all have been coated with the pliable and tough quality of rubber materials of one deck, therefore, whole tube chamber is that relatively pliable and tough, all tractive operation is undamaged to blood vessel and blood vessel wall for blood vessel wall.
Finally, it is also to be noted that, what more than enumerate is only specific embodiments of the invention.Obviously, the invention is not restricted to above examples of implementation, many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention, all should think protection scope of the present invention.
