Medical lengthening monopolar type electromyographic electrode checkout gearTechnical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of medical lengthening monopolar type electromyographic electrode checkout gear.
Background technology
Conventional needle electromyographic electrode needle length is no more than 75mm usually, the curtailment when carrying out percutaneous puncture detection deep nerve (as bone marrow, nerve root) or muscular tissue.In addition, because needle body is comparatively thick, also detection position, deep cannot be arrived at by paracentesis trocar.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of medical lengthening monopolar type electromyographic electrode checkout gear, solves the problem that when carrying out deep nerve or muscular tissue EMG detection, ordinary electrode pin length is inadequate.
For achieving the above object, one described in the utility model medical lengthening monopolar type electromyographic electrode checkout gear, comprise the puncture casing that appearance scribbles insulating barrier, and enter monopolar type electromyographic electrode pin in body by running through this puncture casing pipeline, wherein, described monopolar type electromyographic electrode pin comprises the needle body that head is taper, and the afterbody of described needle body is electrically connected with a signals collecting cable, and needle body and signals collecting cable connection location place are provided with needle handle; The surface of described needle body is covered with lid Teflon insulating coating, and needle body head 1-2mm is exposed on the external; The length 1-3mm longer than puncture casing length of described needle body, described needle body is circular, and its diameter is 0.35-0.4mm.
Preferably, described needle handle is circular, and its length is 2-3cm, and diameter is 3.5-4mm.
Preferably, the length of described needle body is 180-185mm.
Preferably, described needle handle is plastics or metal needle handle.
The beneficial effects of the utility model are:
This utility model can provide enough length to reach deep nerve or muscular tissue, and has again the conduction of puncture casing, and needle body can not be caused easily to bend in piercing process and depart from target.
Accompanying drawing explanation
Fig. 1 is the structural representation of medical lengthening monopolar type electromyographic electrode checkout gear described in this utility model embodiment.
Detailed description of the invention
Below in conjunction with Figure of description, this utility model is further described.
Be illustrated in figure 1 a kind of medical lengthening monopolar type electromyographic electrode checkout gear, comprise the puncture casing 4 that appearance scribbles insulating barrier, and enter monopolar type electromyographic electrode pin in body by running through this puncture casing pipeline, wherein, described monopolar type electromyographic electrode pin comprises the needle body 3 that head is taper, can alleviate the damage to N&M tissue.The afterbody of described needle body is electrically connected with a signals collecting cable 2, for the collection organizing electromyographic signal.Needle body and signals collecting cable connection location place are provided with needle handle 1, and described needle handle is plastics or metal needle handle, and it is circular, and length is 2-3cm, and diameter is 3.5-4mm.The junction point of protection needle body and signals collecting cable can be played and conveniently hold.The surface of described needle body is covered with lid Teflon insulating coating, and needle body head 1-2mm is exposed on the external, to gather the signal of telecommunication.The length 1-3mm longer than puncture casing length of described needle body, described needle body is circular, and its diameter is 0.35-0.4mm, and under normal circumstances, the length of described needle body is 180-185mm.
In use, the sleeve pipe that described puncture casing uses for paracentesis trocar, is first punctured to paracentesis trocar in deep nerve or muscular tissue, then extracts trocar nook closing member.Again monopolar type electromyographic electrode pin is inserted from puncture casing, the head of needle body can be touched in deep nerve or muscular tissue, complete the collection of the signal of telecommunication.This utility model can provide enough length to reach deep nerve or muscular tissue, and has again the conduction of puncture casing, and needle body can not be caused easily to bend in piercing process and depart from target.
Above; be only preferred embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that this utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.
