Description
Technical field
This utility model belongs to a kind of medical instrument, and especially relating to a kind of plexus nervorum stimulates the trocar.
Background technology
Periphery neural blocking anesthesia was all that the probability of injured nerve is larger according to dissecting puncture under positioning blind spy on book in the past, used after the guiding of nerve stimulation instrument damage probability reduction, and the effect of periphery neural blocking anesthesia and the very large lifting of degree of reliability acquisition.But existing conventional plexus nervorum stimulates the trocar, as the insulation nerve stimulation pin of Bei Lang company, brings a high price at present, the expense of this respect is not submitted an expense account in medical insurance, so outstanding aobvious expensive for the patient of basic hospital.
Utility model content
The technical problems to be solved in the utility model is to provide plexus nervorum stimulates the trocar, can solve one or more in above-mentioned prior art problem.
According to an aspect of the present utility model, provide plexus nervorum to stimulate the trocar, comprise steel entry needle, calparine cap, remove the artery puncture trocar of afterbody and the electric wire with alligator clamp, calparine cap is arranged on the tail end of artery puncture trocar, and steel entry needle penetrates artery puncture trocar by calparine cap, and the head of steel entry needle is connected with the metal needle inner core of artery puncture trocar trocar sheath tail end.
Its beneficial effect is: calparine cap can be fixed the position of steel entry needle shank, can arbitrarily not shake or rotate, the syringe needle of steel entry needle is connected with the metal needle inner core of artery puncture trocar, realize conduction, when use, alligator clamp is clipped on the shank of steel entry needle, electric current is delivered to the syringe needle of artery puncture trocar by steel entry needle, the trocar sheath of artery puncture trocar plays good insulating effect, allow electric current only act on the needle point of arterial cannula pin, it is more accurate that electric current is directed at the application point of human body.
In some embodiments, steel entry needle is the steel entry needle that aseptic packaging length is greater than 4cm.So, ensure the shank long enough of steel entry needle, can pass artery puncture trocar, be connected with the metal needle inner core of artery puncture trocar, realize conduction, and can reserve position to alligator clamp, aseptic packaging has ensured the safe and sanitary of material therefor.
In some embodiments, calparine cap is aseptic packaging calparine cap.Aseptic packaging has ensured the safe and sanitary of material therefor.
In some embodiments, artery puncture trocar aseptic packaging is 22G or 24G artery puncture trocar.22G or 24G artery puncture trocar are the conventional radial artery puncturing trocar compared with ting model, avoided thick injured nerve, indwelling trocar sheath can also repeatedly or continuously inject local anaesthesia mixed liquor, and the external diameter that the metal needle internal diameter of 22G or 24G artery puncture trocar and length are greater than the steel entry needle of 4cm matches, can realize good connection, be conducive to conduction, aseptic packaging has ensured the safe and sanitary of material.
The beneficial effects of the utility model are: material therefor is common medical material, and 10 yuan of cost less thaies are cheap, and easily assembling, are used in conjunction with existing nerve stimulation instrument, respond well, very large to the use value of basic hospital.
Brief description of the drawings
Fig. 1 is the structural representation that this utility model plexus nervorum stimulates a kind of embodiment of the trocar;
Fig. 2 is the using state schematic diagram that this utility model plexus nervorum stimulates the trocar.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Fig. 1 has provided this utility model plexus nervorum stimulates an embodiment of the trocar: in this embodiment, plexus nervorum of the present utility model stimulates the trocar mainly to comprise steel entry needle 1, calparine cap 2, removes the artery puncture trocar 3 of afterbody and the electric wire 4 with alligator clamp 41.The steel entry needle that steel entry needle 1 is aseptic packaging length 5cm, calparine cap 2 is aseptic packaging calparine cap, artery puncture trocar 3 is aseptic packaging 22G artery puncture trocar.Calparine cap 2 is arranged on the tail end of artery puncture trocar 3, and steel entry needle 1 penetrates artery puncture trocar 3 by calparine cap, until the head 13 of steel entry needle 1 is connected with metal needle 32 inner cores of artery puncture trocar 3 trocar sheath 31 afterbodys.
As shown in Figure 2, when use, alligator clamp 41 is clipped on the shank 12 of steel entry needle 1, and electric wire 4 connects the bright nerve stimulation instrument of shellfish, and the bright nerve stimulation instrument of shellfish electric current is set to 1.0MA, and frequency is 2HZ.Near 32 arrival of artery puncture trocar syringe needle are neural time, see related muscles joint motions, electric current is turned 0.3MA down, still while there are related muscles joint motions, fix artery puncture trocar, then the local anesthetic configuring is injected by the afterbody 11 of steel injection needle 1, complete periphery neural blocking anesthesia one time.Inject completely, also the trocar sheath of artery puncture trocar 3 31 can be inserted to nerve sheath for subsequent use, can re-inject anesthetis.
In this embodiment, material therefor is common medical material, and 10 yuan of cost less thaies are cheap, and easily assembling, is used in conjunction with existing nerve stimulation instrument, respond well, very large to basic hospital use value.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of this utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
