Description
Technical field
The present invention relates to medical surgical instrument, especially a kind of for giving the spine epidural minimally-invasive catheter of epidural nerve transfusion.
Background technology
Epidural nerve is very narrow and small, for its transfusion must arrange a kind of very small conveyer device, and will keep the stability of infusing and the amount of infusion accurately controlled in a period of time in course of conveying.
The neural infusion set of epidural conventional at present adopts extruding control structure, push away liquid sheet along tube for transfusion layout is multiple mostly, utilization pushes away liquid sheet and continuously extrudes tube for transfusion from bottom to top, thus realize automatic infusion, but after being through repeatedly extruding, the flexibility decrease of tube for transfusion can be caused, reduce the actual life of tube for transfusion.The more important thing is that common transfusion device is general all larger, be not suitable for the transfusion of epidural nerve.
Summary of the invention
Technical problem to be solved by this invention is to provide the spine epidural minimally-invasive catheter of the amount of bleeding that a kind of simple operation is flexible, wound is little, reduction is performed the operation.
The present invention's adopted technical scheme that solves the problem is: this conduit comprises handle and tube core, its construction features is in handle, 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, little flow-guiding channel is provided with in diversion column, 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; Be provided with the steel wire be connected with slide block in tube core, in handle, be also provided with the slide rail be slidingly fitted with slide block, handle is also provided with the handle with slide block engaged transmission.
Slide block of the present invention is provided with groove A, handle is provided with groove B, 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.
Be provided with bracing frame in handle of the present invention, guiding tube is arranged on bracing frame.
The present invention also includes the puncture needle be made up of inner sleeve and trocar sheath.
The present invention compared with prior art, there is following beneficial effect: this infusion set compact, structure is simple, simple operation is flexible, only need pull handle gently, tube core can be driven to bend by steel wire, after tube core inserts puncture needle trocar sheath, 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 infuse to the Wicresoft of the epidural such as chronic low back pain, lumbar spinal stenosis nerve.
