Abstract
The utility model relates to the medical-surgical instruments and particularly relates to a spinal-epidural mini-invasive catheter for infusion to epidural nerves. The catheter comprises a handle and a pipe core, wherein the rear end of the pipe core is arranged in the handle; the pipe core is internally provided with a guiding wire; a spring is arranged at the front end of the guiding wire, and the rear end of the guiding wire is fixed on the handle. The spinal-epidural mini-invasive catheter also comprises a puncture needle consisting of an inner sleeve and an outer sleeve. The spinal-epidural mini-invasive catheter has the advantages of convenient and flexible operation, less tissue wound, high use safety performance and less side effect.
Description
Technical field
This utility model 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, when use, must first puncture again through skin anesthesia; 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.For the patient of the chronic slight illness for the treatment of, also need prolonged stay conduit, make patient activity inconvenience, also easily strengthen 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 in the utility model 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 technical scheme in the invention for solving the above technical problem is: 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.
This utility model also comprises the puncture needle being made up of inner sleeve and trocar sheath.
This utility model compared with prior art, there is following beneficial effect: the seal wire front end of this conduit is provided with spring, in the time 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 such as chronic low back pain, lumbar spinal stenosis nerve.

Below in conjunction with drawings and Examples, this utility model is further illustrated.
Fig. 1 is the perspective view of this utility model main body.
Fig. 2 is the cross-sectional view of this utility model main body.
Fig. 3 is the A enlarged drawing of Fig. 2.
Fig. 4 is the perspective view of this utility model puncture needle.
Fig. 5 is the cross-sectional view of this utility model puncture needle.
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 made up 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 made up 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.
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, in 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.
