Description
Technical field
The utility model relates to medical thrust technical fields, and in particular to a kind of sting device.
Background technique
The double-jacket tube that existing clinical operation uses, often needs underwent operative to place to position of disease and is rinsed and treats, and for
No operation patient or can not be resistant to the patient of operation there is no it is a set of integrate puncture, placement, irrigation and drainage double-jacket tube dress
It sets.Therefore often only passive drainage existing for such patient, or interruption water filling irrigation and drainage is repeatedly punctured, curative effect it is also to be difficult to
It is satisfied.
Clinic puncture drainage is that Seldinger sets tube method using more method at present, and the puncture mode of the technology is
Target penetrating area is positioned through ultrasound or CT.It using lidocaine local anaesthesia and is soundd out after sterile drape in target area, after
It uses puncture needle instead and is vertically pierced into epidermis until reaching target depth (can be by positioning such as syringe extraction or ultrasound, CT), insert
Enter seal wire, after determining that seal wire has entered target area, exits puncture needle, and at gauze pressing puncture.It is led along seal wire insertion
Pipe (can be first inserted into for several times along seal wire with the expander of thickness same as conduit when necessary, to expand wound road, conduit be made to be easy to logical
Cross, extract expander, then be inserted into conduit along seal wire), seal wire is extracted, three-way cock and drainage bag are connected.Finally conduit is carried out
Part is fixed, disinfection.Conduit it can be drained or be administered whereby.But such conduit has no individual water inlet line and gives part
Lasting water inlet is rinsed, therefore cannot keep lasting local cleaning action, while the also often blocking such as local organization, foreign matter, sludged blood
Lumen keeps drainage effect unsatisfactory.
And the double-jacket tube for being placed in operation, the ability with continual rinsing drainage, and since it is relatively more advantageous
Placement location, therefore cleaning capacity drains more merely often more preferably clinical effectiveness.But clinically current this used
There is no the functions that independently puncture for class double-jacket tube, therefore for No operation or can not be resistant to the patient of operation, and such disadvantage limits
Its clinical application.
Also, since puncture needle in the prior art, conduit, seal wire are individual components, in puncture process, need point
Other each component of independent operation, step is complex cumbersome, also limits the application of current drainage catheter.
