Novel segmental epidural catheterTechnical field
This utility model belongs to a kind of medical apparatus, specifically, relates in particular to a kind of novel segmental epidural catheter.
Background technology
Epidural block is a kind of anesthesia of wide clinical application, is widely used, have simple to operate, the characteristics that cost is low.When existing anesthetic tube uses on the market two kinds of situations can take place: a kind of is that material hardness is big, and conduit is easy to operate inserts in the body, but stab easily muscle and ligamenta flava tissue, tissue blood vessel and nerve, the situation of tissue blood vessel damage is particularly outstanding; If insert complication such as causing the spinal dura mater breakage probably by force, epidural catheter chamber blood back and clottage conduit are the common factors of epidural anesthesia failure.Another is that material hardness is little, puts the pipe operating difficulties, commonly puts pipe difficulty, to be detained the position not good, extracts the generation of situations such as difficulty.At present, also there are not a kind of not only operation but also the muscle that can not stab, ligamenta flava tissue, tissue blood vessel and neural segmental epidural catheter easily.
Summary of the invention
In order to solve in the prior art, segmental epidural catheter hardness is big stabs patient, the defective of inserting difficulty that hardness is little easily, and this utility model provides a kind of novel segmental epidural catheter.
This utility model is achieved through the following technical solutions:
A kind of novel segmental epidural catheter, it comprises pipe shaft, an end of pipe shaft is provided with joint, the other end of pipe shaft is provided with tube head, the hardness of tube head from front end toward the pipe shaft direction by soft hardening gradually.
Compared with prior art, the beneficial effects of the utility model are: the material hardness of tube head from front end toward the pipe shaft direction by soft hardening gradually, make that head is flexible, easily insert, the head softness is not easy damaged tissue, do not injure spinal dura mater, simultaneously, be convenient to the doctor yet conduit is inserted in the human body, avoid the complication of operation to occur, improved the success rate and the safety of epidural anesthesia.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is further specified:
1, tube head; 2, pipe shaft; 3, joint.
A kind of novel segmental epidural catheter, it comprises pipe shaft 2, and an end of pipe shaft 2 is provided with joint 3, and the other end of pipe shaft 2 is provided with one to three millimeter tube head 1, by soft hardening gradually, the hardness of the end of tube head 1 reaches consistent with pipe shaft 2 to the hardness of tube head 1 from front end toward the pipe shaft direction.
