Abstract

The utility model provides a specialized casing needle for ultrasonic interventional therapy in medical technology field. The casing needle is mainly characterized in that the stylet is hollow, the end of the tip part is as an acuminate bevel, the exterior of the tip is provided with a textured acoustics marked layer, the end of the casing is gradually thinner, with side holes thereon; the end structure is as potential pigtail. The textured acoustics marked layer is also arranged on the end part of the reserved solid styet. Compared with prior technology, the utility model has advantages of minimal surgical wound, the capability of observing and adjust the position of the needle tip, difficulty of being blocked, and less material consumed, etc.

Description

Ultrasonic interventional therapy specialized barrel needle set

This utility model belongs to the armarium technical field, is a kind of ultrasonic interventional therapy specialized barrel needle set.

In clinical ultrasound interventional therapy process, at present, various puncture needles and conduit are arranged, but the place of such or such not person of modern times meaning is always arranged, for example: 1, sleeve pipe takes off after being pushed up when being punctured to the skin aponeurosis (aponeuroses) easily; 2, in processes such as puncture suction injection, be difficult for observing the position of needle point and cannula tip, and lose objects; 3, obstruction etc. takes place in single hole pipe easily.Simultaneously, many with material, seance needs standby a plurality of solid nook closing members.

It is little that the purpose of this utility model provides a kind of art wound, can observe the adjustment tip position, is difficult for stopping up the sleeve pipe needle set that consumptive material is few.

Technical solution adopted in the utility model is improved on the basis of existing needle tubing tool, its main feature is a nook closing member hollow, needle point position, end is sharp keen inclined-plane, the outer setting of needle point has the acoustics reference lamina of handling through texturing, telescopic tail end is for carefully approaching shape gradually, pipe end has side opening, and end structure is potential pigtail shape.The end of standby solid nook closing member has the acoustics reference lamina of handling through texturing equally.

Because this utility model taked technique scheme, advantage such as compared with prior art, it is little to have the art wound, can observe the adjustment tip position, is difficult for stopping up, and consumptive material is few.

Below in conjunction with accompanying drawing and example specific structural features of the present utility model is described further.

Fig. 1 represents general assembly structural representation of the present utility model

As shown in Figure 1, the utlity model has sleeve pipe 1, puncture nook closing member 2 and standby solid nook closing member 3, its main feature is puncture nook closing member 1 hollow, and needle point 4 ends are sharp keen inclined-plane, and there is the acoustics reference lamina of handling through texturing 5 needle point 4 outsides.The tail end of sleeve pipe 1 is carefully thin gradually, and pipe end has side opening 6, and this end structure has potential pigtail shape 7.The end of standby solid nook closing member 3 has the acoustics reference lamina of handling through texturing 8 equally.

Because the design of its sleeve pipe head end has the zone that narrows down gradually and have texturing to handle, so its sleeve pipe contacts with nook closing member closely, the reasonable distribution design of its side opening in addition, make condom be difficult for taking off after being pushed up when organizing being punctured to skin aponeurosis (aponeuroses) etc. matter is tough, but successfully penetrate into specified position with sharp keen needle point; Secondly, the acoustics sign that its texturing is handled, can in processes such as puncture, suction, injection, observe needle point and cannula tip the position and in time adjust, be unlikely to the situation of lose objects in said process, to occur and influence intervention diagnosis and therapy carrying out and the success; As for well fixedly being, prevent that sleeve pipe from deviate from sleeve pipe with internal organs and operational movement because cover closes the natural torsion that the curved design of head end forms after extracting nook closing member; Structure resemble the side opening is used for being convenient to fully flushing and convenient suction in addition, and this has overcome the problem of the easy obstruction of single hole pipe in the past, and simultaneously, in a single day the solid nook closing member of that nose circle gets clogged at pipe is to come dredging pipeline and be unlikely to make the treatment failure with it.

Claims

1, a kind of ultrasonic interventional therapy specialized barrel needle set, have sleeve pipe, puncture nook closing member and standby solid nook closing member and it is characterized in that nook closing member hollow, needle point position, end is sharp keen inclined-plane, the outer setting of needle point has the acoustics reference lamina of handling through texturing, telescopic tail end is for carefully approaching shape gradually, pipe end has side opening, and end structure is potential pigtail shape, and the end of standby solid nook closing member has the acoustics reference lamina of handling through texturing equally.
