Abstract
The subcutaneous tunnel guiding needle is capable of establishing a subcutaneous tunnel rapidly and consists of a hollow puncture needle, a needle core with threads and a handle, wherein the hollow puncture needle sleeved into the needle core is rotatably fixed onto the threads and connected with the handle, the length of the puncture needle is fifteen centimeters and the diameter of the puncture needle is two millimeters. When the subcutaneous tunnel is established, the puncture needle is rotatably fixed onto the handle and punctured into the skin from a position of skin through which a hard film outer guiding tube penetrates, and then is moved upwards by twelve centimeters to puncture out of the skin and a tip is revealed, the handle is turned to lead the needle core to be out, the hard film outer guiding tube is positioned into the skin through a tail of the puncture needle and the head end of the puncture needle is led out, the puncture needle is pulled out by the tip, and finally the hard film outer guiding tube and the skin are fixed.
Description
Technical field
This utility model relates to the new equipment through the long term administration of subcutaneous tunnel, can conveniently set up hypodermic tunnel, and reduces damage.
Background technology
In the clinical research of chronic pain (cancer pain) or treatment, insert through epidural space that conduit is long-term, to continue medication be a kind of method of definite effect; But epidural catheter needs to draw through subcutaneous tunnel, infects otherwise easily cause.And still there is following problem in the method for setting up hypodermic tunnel at present: the too short conduit fixed effect that causes of 1 hypodermic tunnel is imprecise, and infection potential is higher.2 utilize anesthesia spinal needle to carry out retrograde puncture guiding causes the conduit damage easily, and repeated multiple times sets up the tunnel and need do skin incision, increases damage, infects probability.
Summary of the invention
Existingly set up the loaded down with trivial details of hypodermic tunnel method and shortcomings such as damage is big, easy infection in order to overcome, this utility model provides a kind of hypodermic tunnel guide needle, and this device can be set up hypodermic tunnel quickly and easily.
The technical scheme that its technical problem that solves this utility model adopts is: have the hollow puncture needle afterbody of scale mark to join by internal whorl and one handle with one, the puncture needle nook closing member is fixed in handle, the nook closing member near handle end is connected the long 15cm of puncture needle, diameter 2mm after by the rotation of external screw-thread and puncture needle internal whorl mutually.When building hypodermic tunnel, the puncture needle rotation is fixed on the handle, going out the skin place through epidural catheter thrusts subcutaneous, puncture out the skin and expose head end of about 12cm place of upwards advancing, rotary handle also withdraws from nook closing member, with epidural catheter through the puncture needle afterbody insert, head end draws, puncture needle is pulled out from head end, fixedly epidural catheter and skin.
The beneficial effects of the utility model are can set up hypodermic tunnel quickly and easily, the probability that reduces damage and infect.
Description of drawings
Among the figure: 1, the puncture needle head end; 2, puncture needle; 3, the puncture needle tail end; 4, nook closing member; 5, screw thread; 6, handle.
The specific embodiment
In the drawings, the hollow puncture needle (2) of long 15cm, a diameter 1mm is inserted in nook closing member (4) back rotation, joins and fixing by screw thread (5) and handle (6).When building hypodermic tunnel, puncture needle (2) is gone out the skin place through epidural catheter to be thrust subcutaneous, puncture out the skin and expose puncture needle head end (1) of about 12cm place of upwards advancing, rotary handle (6) also withdraws from nook closing member (4), with epidural catheter through the puncture needle afterbody insert, head end draws, puncture needle (2) is pulled out from head end, fixedly epidural catheter and skin.
Claims (1)
1. a hypodermic tunnel guide needle is made up of hollow puncture needle, screwed nook closing member and handle, it is characterized in that: described hollow puncture needle rotates to be fixed on the screw thread and with handle after being inserted in nook closing member and is connected.
