Together, the needle core end is equipped with blunt type puncture portion.
Further, the length of the needle core is greater than the length of magnetic orientation coil, and the internal diameter of the needle core is greater than magnetic
The diameter of set winding.
Further, the length of the needle core is greater than the length of casing.
Further, the needle stand is back taper needle stand, which is equipped with stay hook, the rope matched
Ring.
It further, further include the protective film being located in the needle core for electromagnetic sensor to be isolated with needle core.
Compared with prior art, the utility model has the advantage that as follows:
1. a kind of puncture needle of the utility model, uses the needle core of hollow structure, can cooperate with electromagnetic sensor makes
With, can be used for magnetic orientation puncture；It connects and fixes needle core and casing by needle stand and casing guide bracket, thus, the utility model is also
Have the characteristics that structure is simple and convenient to operate.
2. a kind of puncture needle of the utility model uses the casing of hollow structure, thus, it can be used for injecting drug, clear
The characteristics of except lesion.
3. a kind of puncture needle of the utility model uses end for the needle core in the puncture portion of blunt type, thus, there is structure
Simply, the characteristics of reducing surgery side effect.
4. a kind of puncture needle of the utility model passes through the stay hook and grommet and the fixed electricity of cord outside cooperation on needle stand
Magnetic Sensor reduces the complexity of puncture needle.
5. a kind of puncture needle of the utility model, by protective film puncture needle and reusable electromagnetic sensor,
Thus safety and sanitation.

Specific embodiment
With reference to embodiment, the technical solution of the utility model is described in further detail, but not structure
Any restrictions of pairs of the utility model.
Embodiment one
As shown in Figures 1 to 3, a kind of puncture needle of the utility model comprising hollow casing 2 and magnetic orientation line can be made
Circle penetrates its internal needle core 1, and 1 top side of needle core is equipped with the needle stand 11 and the needle stand 11 that are capable of fixing electromagnetic sensor and needle core
1 is connected, and the needle stand 11 is used cooperatively with more other medical instruments when necessary；2 top side of casing is equipped with casing guide bracket 21, set
When pipe 2 is sleeved on needle core 1, fixation procedure is that needle stand 11 is inserted into casing guide bracket 21 first, and then needle stand 11 is led with casing
21 relative rotation certain angles of seat connect and fix needle core 1 and casing 2 together；1 end of needle core is equipped with blunt type puncture portion 12.Cause
This, also there is a kind of puncture needle the utility model of the utility model structure to be simple and convenient to operate, can the spy that punctures of magnetic orientation
Point.
A kind of puncture needle of the utility model, the length of needle core 1 are greater than the length of magnetic orientation coil, the internal diameter of needle core 1
