Therefore operate more simple and convenient, do not need too much practical experience also can operate.
In above-mentioned a kind of Novel puncture needle, described puncture needle head is provided with gear edge on endoporus one, and protruding two when being resisted against on needle stand afterbody, described needle tubing head and gear along one end against, and described nook closing member seamlessly can be fitted in gear along on inner face.
Therefore skin puncture process is more smooth.
In above-mentioned a kind of Novel puncture needle, the outer wall of described puncture needle is provided with scale, and puncture needle is also arranged with limited block, and limited block can move along needle length direction.
According to puncture depth of needle determination limited block position, therefore use also very convenient.
In above-mentioned a kind of Novel puncture needle, described limited block and puncture needle outer wall are spirally connected, and limited block is curved towards the end face of puncture needle head.
Compared with prior art, tool of the present invention has the following advantages:
By lancet puncture skin and after arriving object tissue, taken out by nook closing member, needle stand connects syringe.Biopsy enters in the endoporus two of needle tubing by the negative pressure-pumping of syringe, as some notches one and notch two block time, by other notch one and notch two, biopsy is sucked, biopsy in endoporus two is sucked by notch one and notch two afterwards by rotating needle tubing cutting, reach a pin multidraw object, and it is fast very convenient to cut off biopsy process, reduce the misery of patient.
