Abstract

The invention relates to medical surgical instruments, in particular to a spine epidural external minimally invasive catheter for infusion of epidural nerves. The catheter comprises a handle and a catheter core, wherein the rear end of the catheter core is arranged in the handle, a guide wire is arranged in the catheter core, the front end of the guide wire is provided with a spring, and the rear end of the guide wire is fixed on the handle. The spine epidural external minimally invasive catheter further comprises a puncture needle composed of an inner sleeve and an outer sleeve; the inner sleeve is made of medical elastic high polymer material which is polyamide or polyphenylene sulfone or teflon. The spine epidural external minimally invasive catheter has the advantages of being portable and flexible to operate, small in tissue trauma, high in using safety performance and low in side effect.

Description

The outer Wicresoft of spinal epidural conduit
Technical field
The present invention relates to medical surgical instrument, the especially a kind of outer Wicresoft of spinal epidural conduit of giving the neural transfusion of epidural.
Background technology
At present, puncture needle needle body used is generally all larger, and in have pin stamen, during use, must first through skin anesthesia, puncture again; After puncturing successfully, extract pin stamen and do negative pressure or gas injection test, confirm after epidural space is errorless, in pin hole, to insert again conduit, from conduit injection of medicine.Patient for the chronic slight illness for the treatment of, also needs prolonged stay conduit, makes patient activity inconvenient, also easily strengthens the chance infecting, simultaneously complex operation.And because needle body is thick, puncture is very large to the damage of tissue, easily causes hemorrhage or form epidural space hematoma, if careless manipulation even there will be sequela such as wearing out dura mater.These are all the limitation of traditional Epidural treatment.
Summary of the invention
Technical problem to be solved by this invention is to provide the outer Wicresoft of the spinal epidural conduit that a kind of simple operation is flexible, tissue injury is little, usage safety performance is high, side effect is little.
The present invention addresses the above problem adopted technical scheme: the main body of this conduit comprises handle and tube core, and the rear end of tube core is arranged in handle, is provided with seal wire in tube core, and the front end of seal wire is provided with spring, and the rear end of seal wire is fixed on handle
The present invention also comprises the puncture needle being comprised of inner sleeve and trocar sheath.
Inner sleeve of the present invention is made by elasticity medical polymer material.
Elasticity medical polymer material of the present invention is polyamide, PPSU or politef.
The present invention compared with prior art, there is following beneficial effect: the seal wire front end of this conduit is provided with spring, when meeting with obstruction, can elasticity pass, simple operation is flexible, make surgical wound very little, reduced the amount of bleeding of operation, usage safety performance is high, side effect is little, is applicable to Wicresoft's transfusion of the epidural nerves such as chronic low back pain, lumbar spinal stenosis.

In figure: 1-seal wire, 2-handle, 3-tube core, 4-spring, 5-inner sleeve, 6-trocar sheath.
The specific embodiment
The present embodiment is comprised of main body and puncture needle.
Referring to Fig. 1-Fig. 3, main body comprises handle 2 and tube core 3, and the rear end of tube core 3 is arranged in handle 2, is provided with seal wire 1 in tube core 3, and the front end of seal wire 1 is provided with spring 4, nested being fixed on handle 2 in rear end of seal wire 1.
Referring to Fig. 3 and Fig. 4, puncture needle is comprised of inner sleeve 5 and trocar sheath 6.
The rear end of seal wire 1 also can screw thread be fixed or other modes are fixed on handle 2.
Inner sleeve 5 is made by elasticity medical polymer materials such as polyamide, PPSU or politef.
The using method of the present embodiment is as follows:
Puncture needle is inserted in patient body, pull out puncture needle inner sleeve 5, the front end of tube core 3 is penetrated in patient body along puncture needle trocar sheath 6, the front end of seal wire 1 is provided with spring 4, when meeting obstruction, can elasticly pass, and adjusts position, make the position alignment needs of patients transfusion part of tube core 3, then pull out seal wire 1, hybrid medicine is injected from tube core 3 rear ends, hybrid medicine is injected in vivo along tube core 3.
