The kidney sampling puncture needle that pain can effectively be mitigated and reduce wound, the other end of bodkin stalk are equipped with circular slanting Face forms chamfered transition by annular slope and half round needle stalk, opening.
The kidney sampling puncture needle that pain can effectively be mitigated and reduce wound, the another half of face in needle point major part one end It is equipped with the briquetting of protrusion, the outer wall of briquetting is set as inclined-plane, and inner needle tube one end end is equipped with gap, and the briquetting forms interior The gap of the fastening of outer inclined-plane described in needle tubing one end, wherein inner needle tube is positioned close to half round needle stalk side.
The kidney sampling puncture needle that pain can effectively be mitigated and reduce wound, the block is circular configuration, is being covered Cap is equipped with pit, and the pit is buckled on the socket B one sides of interior pintle, and concave surface is equipped in the pit opposite face of block.
The kidney sampling puncture needle that pain can effectively be mitigated and reduce wound, in the inner needle tube one of interior pintle exterior face Side is equipped with arcwall face, and the socket A kisses of the arcwall face and outer pintle are matched.
The kidney sampling puncture needle that pain can effectively be mitigated and reduce wound, the exterior face both sides point of the outer pintle Not She You concave face, on outer pintle be equipped with connecting cylinder, bodkin stalk is connected in connecting cylinder.
By above disclosure, the beneficial effects of the invention are as follows:
The kidney sampling puncture needle of the present invention that pain can effectively be mitigated and reduce wound, is implementing human kidney disease hand When art treats or checks, for the needle point obstructed using bodkin as puncturing, the inner needle tube under being covered by needle point can effectively mitigate puncture Pain and reduction skin histology in the process is mingled in kidney living tissue, can be obtained more clean kidney living tissue, be facilitated Sample examination and implementation radiography;Present invention operation is easy to use, the drawbacks of effectively preventing existing kidney puncture needle, especially convenient It the excision of nephridial tissue and takes out of.
