The needle body of the puncture needle is made of heat insulation materials, heat insulation aluminum alloy can be used, the needle point of the puncture needle is made of heat conduction materials, copper metal can be used, an electric heating wire penetrates through the puncture needle, and the electric heating wire is connected with the needle point of the puncture needle.

Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: medical personnel judge the thickness of treating the perforation body wall according to the image examination result, then adjust the position of location short sleeve, the distance that makes spacing ring pad and puncture head is a bit greater than the thickness of body wall, avoid damaging patient's internal organ because of the puncture dynamics is too fierce, turn on switch, punch to the patient body wall, puncture head front end lamp holder can throw light on to the patient is internal, through the better position of judgement puncture head of shining of lamp holder, behind the pjncture needle external power supply, when the puncture, can burn the puncture to the internal membranous tissue of patient, thereby reduce the puncture resistance, make and stab the card and more easily puncture membranous tissue and get into the patient body intracavity.

To sum up, adopt the utility model discloses when medical personnel carry out the body wall to the patient and punch, avoid damaging the internal organ of patient because of inertial action.
