Description
Technical field
The utility model belongs to medical equipment technical field, and in particular to a kind of electrode needle and its safety protective tube.
Background technology
Nervous system is guarded in clinical operation（Intraoperative Neuromonitoring IONM）Or in operation
Electrophysiology is monitored（Intraoperative Neurophysiological Monitoring）Refer to utilize neuroelectricity life
The method of of science and brain blood-oxygen, understands during neurotransmission, the change of electricity physiological signal understands brain tissue metabolism
The change of function, understands brain blood perfusion situation, so that effectively assistance surgical doctor is instant, comprehensively understand narcosis
The integrality of lower patient's nervous function, it is to avoid neurotrosis and prevention of postoperative nervous function in operation are damaged.
In the U.S. and countries in Europe, Electrophysiology monitoring is had become outside cranial surgery, tumor of spinal cord excision, backbone
Standardized operation in section's operation.At present, Chinese neurosurgery association and osteology can spinal surgery and major teaching doctors
The related surgical section office of institute all use this technology in positive support and encourage.It is average to have more than 5000 daily by taking the U.S. as an example
Example operation needs Electrophysiology to monitor.Average each Neural monitoring needs 20-40 to the subcutaneous pin electrode of two-wire.Entire United States are to skin
The average daily demand of lower pin electrode is very big.Subcutaneous pin electrode is subcutaneously inserted to target muscles from patient does corresponding electromyogram
Record；The corticocerebral somatosensory evoked potentials of hypodermic needle electrode test on head；Subcutaneous pin electrode applies also for piercing through cranium electricity
Zona rolandica domain is swashed, to monitor downward movement fibre bundle.
When subcutaneous pin electrode penetrates skin and applies in patient, all pin electrodes are considered as carrying transmission of dangerous blood-borne
Substance, these pin electrodes are each destroyed using needing.The hypodermic needle electricity of current food and drug administration's accreditation
Pole is all without any safety and Protection.The accident that syringe needle after being contaminated accidentally is pricked is almost daily all in the hand of various regions
Art occurs in room.20-40 is tackled in the operating room of time preciousness to two-wire pin electrode, neurophysiologist, neuroelectricity prison
The accident frequency rate pricked depending on technical staff, nurse, anesthetist, surgeon and room cleaning personnel by syringe needle is very high.
Completing an operation needs team unity, and particularly at the beginning and end of operation, many surgical work personnel are needed in same
Time works with patient.Whole pin electrodes must from a patient take out in patient before anesthesia recovery.10-20 is to most long
Taken out from a patient respectively up to 2.5 meters of pin electrode, the syringe needle of removal is just directly exposed to outer, pin electrode to the last
Collect and processing before, during this period of time, all surgical work personnel have the danger that contaminated syringe needle is pricked, have because
This and by harmful blood-borne pathogens and infectious disease virus infect, including human immunodeficiency virus (HIV), hepatitis B,
Hepatitis C and creutzfeldt-Jacob disease (CJD).
Food and drug administration (FDA) approval subcutaneous pin electrode once property use, use repeatly, staight needle
With crochet hook etc..Most commonly disposable staight needle electrode, by a metal needle (stainless steel, platinum, tungsten etc.), connecting tube, wire
A unit is constituted jointly with a line trap.This pin electrode by sterilization be packaged as it is single or in pairs for doctor and
Qualified technical staff is disposable.
Chinese utility model patent discloses a kind of subcutaneous pin electrode and its safety protective tube is set, for multiple use
