Description
Technical field
The present invention relates to medical surgical instrument, especially a kind of for giving the outer Wicresoft of the spinal epidural conduit of the neural transfusion of epidural.
Background technology
Epidural nerve is very narrow and small, for its transfusion must arrange a kind of very small conveyer device, and in course of conveying, will keep the stability of transfusion and accurately control the amount of infusion in a period of time.
The neural infusion set of at present conventional epidural adopts extruding control structure, to arrange a plurality of liquid sheets that push away along tube for transfusion mostly, utilization pushes away liquid sheet and continuously pushes tube for transfusion from bottom to top, thereby realize automatic infusion, but after repeatedly pushing, the flexibility decrease that can cause tube for transfusion, the actual life of reducing tube for transfusion.The more important thing is that common transfusion device is generally all larger, be not suitable for the neural transfusion of epidural.
Summary of the invention
Technical problem to be solved by this invention is to provide the outer Wicresoft of the spinal epidural conduit of the amount of bleeding that a kind of simple operation is flexible, wound is little, reduction is performed the operation.
The present invention addresses the above problem adopted technical scheme: this conduit comprises handle and tube core, its construction features is in handle, to be provided with guiding tube, tube core and slide block, the front end of handle is provided with diversion column, the front end of guiding tube is connected with the rear end of tube core by diversion column, in diversion column, be provided with little flow-guiding channel, the front end of guiding tube is connected with tube core by little flow-guiding channel, and handle is stretched out in the rear end of guiding tube; In tube core, be provided with the steel wire being connected with slide block, in handle, be also provided with the slide rail being slidingly fitted with slide block, on handle, be also provided with the handle with slide block engaged transmission.
On slide block of the present invention, be provided with groove A, be provided with groove B on handle, slide block and handle are by groove A and groove B engaged transmission.
The rear end of guiding tube of the present invention is provided with seal wire.
In handle of the present invention, be provided with bracing frame, guiding tube is arranged on bracing frame.
The present invention also includes the puncture needle being comprised of inner sleeve and trocar sheath.
The present invention compared with prior art, there is following beneficial effect: this infusion set volume is small and exquisite, simple in structure, simple operation is flexible, only need pull gently handle, can drive tube core crooked by steel wire, tube core inserts after puncture needle trocar sheath, and medicine is injected in vivo through tube core, little flow-guiding channel and tube core, can reduce the wound of operation, reduce the amount of bleeding of operation, be applicable to the Wicresoft's transfusion to epidural nerves such as chronic low back pain, lumbar spinal stenosises.
