Description
Technical field
The invention belongs to the field of anaesthetizing, and in particular to a kind of positioning remaining needle and its fiber crops for continuous peripheral blockade
Liquor-saturated method.
Background technology
The anesthesia of peripheral blockade has perfect simple to operate, topical pain relief effect, patient's Consciousness, to complete
The advantages of figure rings smaller, so being widely applied among upper and lower extremities operation.But traditional peripheral blockade
Operation uses blind spy puncture method, and this method does not have objective indicator, can only positioned by finding paresthesia repeatedly, easily damage
, there are certain anesthetic risks, it usually needs could be completed by veteran anesthetist in the blood vessel and nerve of surrounding.
Recently as the fast development of medical device, peripheral nerve stimulation instrument obtains universal answer in clinical anesthesia
With its operation principle is to trigger contraction of muscle as objective indicator so that electrical stimulation is dry, can not only increase nerve block puncture
Accuracy, improve the success rate and security punctured, and can avoid causing the blood vessel of surrounding damage, be greatly enhanced
The security of anesthesia.But used nerve stimulation pin can only implement single retardance, once daily at present, and it can not use
In Postoperative Analgesia After, this anesthesia cannot be applied for time longer operation, it is restricted using scope.
The content of the invention
It is an object of the invention to be used for continuous peripheral blockade there is provided one kind for above-mentioned the problems of the prior art
Positioning remaining needle and its anesthesia, can be applied among prolonged operation, and postoperative analgesia is substantially, expands
The application of periphery neural blocking anesthesia method, reduces the adverse reaction caused by systemic vein is eased pain, improves patient's
Comfort level.
To achieve these goals, the present invention is used for the positioning remaining needle of continuous peripheral blockade, by Y types remaining needle and
Two components of nerve positioning pin are constituted；Described Y types remaining needle includes needle stand and respectively along needle stand bottom surface and side extraction
Indwelling flexible pipe and injection catheter；Described nerve positioning pin includes the needle body for being inserted into indwelling flexible pipe inner chamber, and needle body is arranged on
On the needle handle that can be fastened with needle stand, needle handle tail end draws the wire for connecting needle body and nerve stimulation instrument；Described needle body
It is made of conductive material, indwelling flexible pipe, which is adopted, to be made from an insulative material, and the tip extension of needle body is exposed to outside indwelling flexible pipe
Portion.
Length mark is carved with the needle body of the nerve positioning pin.
Described indwelling flexible pipe is made of polyethylene insulation material, and needle body is made of conductive metal material.
Closing cock is provided with the needle stand of the Y types remaining needle, needle body inserts the inner chamber of indwelling flexible pipe through closing cock.
Fluid injection switch folder is installed on described injection catheter.
Described injection catheter end has been provided with the calparine cap of sealing process.
The end of the wire is provided with the input plug for connecting nerve stimulation instrument delivery outlet.
The length of the indwelling flexible pipe is equal with needle body, and the length of the two is 40cm~50cm.
Expose 2mm in the outside that the tip of the needle body extends to indwelling flexible pipe.
The present invention positions the anesthesia of remaining needle for continuous peripheral blockade, comprises the following steps：
Step 1: the positive pole electrode slice of nerve stimulation instrument is connected with patient's Ipsilateral limb, by the negative of nerve stimulation instrument
The input plug connection of pole and wire end, the as needed anatomical position determination of retardance peripheral nerve punctures entry point；
Step 2: the stimulating current for starting setting up nerve stimulation instrument is 1.5mA, when needle point is close to nerve cord, if causing
The muscle Rythmic contractions characteristic dominated, when stimulating current is reduced to 0.5mA, still has contraction of muscle, illustrates that Needle localization is accurate；
Step 3: the needle stand of Y type remaining needles is fixed, needle body is extracted, and makes to be connected to the indwelling flexible pipe of needle stand front end still
So around nerve cord, local anesthetic injection is entered by injection catheter, so far a nerve block is completed
Anesthesia；According to the difference of operating time length, carry out repeatedly or continuous injection is operated；
Step 4: after operation terminates, Postoperative Analgesia After pump to be connected to the end of injection catheter, Postoperative Analgesia After is carried out.
Compared with prior art, the present invention has following beneficial effect：By the positive pole electricity consumption of nerve stimulation instrument when using
Pole piece is connected with patient's Ipsilateral limb, and nerve stimulation instrument output end connects the needle body of nerve positioning pin by wire, as needed
The anatomical position for blocking peripheral nerve determines to puncture entry point, starts setting up stimulating current for 1.5mA, when needle point is close to nerve cord
When, cause dominated muscle Rythmic contractions characteristic, when stimulating current is reduced to 0.5mA, still there is contraction of muscle, illustrate to puncture and determine
Level is true.The needle stand of Y type remaining needles is now fixed, the needle body of nerve positioning pin is extracted, and is connected to the indwelling of needle stand front end
Flexible pipe is still within around nerve cord, and local anesthetic is simultaneously injected into by the needle stand of fixed Y type remaining needles by injection catheter
Go, this completes a nerve block anesthesia., can repeatedly or continuous infusion according to operating time length in anaesthesia process
Local anesthetic, meets operation and requires, it is ensured that anaesthesia process safety, definite effect is reliable.Perform the operation Postoperative Analgesia After after terminating
Pump is connected to injection catheter end, and effective Postoperative Analgesia After, this analgesia mould can be carried out by setting the various parameters of analgesia pump
Formula is not only able to reduce the dosage of opioid drug, reduces the incidence of the systemic adverse reactions such as nausea and vomiting, additionally it is possible to
By blocking sympathetic nerve, prevent from, because pain triggers vasopasm, increasing the CBF of extremity vascular, particularly to the replantation of a severed limb
Operation and row extremity vascular anastomosis operation, can significantly improve the success rate of operation.The present invention's is cheap, anesthesia positioning
Accurately, Postoperative Analgesia After is convenient and reliable, and complication is less, hence it is evident that improve quality of anesthesia and security, improves patients undergoing
Comfort level, the present invention is simple to operate, it is easy to grasp, easy to use, with very high practical value and promotional value.
Further, length mark is carved with the needle body of nerve positioning pin of the present invention, for being seen when nerve block is punctured
Examine and fluid injection switch folder be installed on the depth of inserting needle, injection catheter, injection catheter end has been provided with the calparine cap of sealing process,
Closing fluid injection switch folder during fluid injection, opens fluid injection and switchs to press from both sides again after removing calparine cap, the end connection syringe of injection catheter
Medicine is injected, injection turns off fluid injection switch folder, removes syringe, then screw on calparine cap in the end of injection catheter after finishing.
