Abstract
The utility model discloses a double-layer puncturing needle which is used for extracting the living tissues of internal focus of a human body. The utility model is formed by that a needle core is arranged in a hollow needle head; the head of the needle head is provided with a spiral drill bit; tail part is provided with a wide mouth; the lower part of the hollow part of the needle core is communicated with a spiral groove, and the upper part is communicated with the wide mouth; an inserting depth adjusting screw is arranged on a needle head which is positioned on the hollow needle head; when the utility model is used the depth of inserting the needle is adjusted and is punctured in affected parts; the drill bit of the needle core is clockwise rotated 2 to 4 rings; the needle core is pulled out; remaining objects in the spiral groove of the drill bit, and biopsy can be carried out. The utility model has the advantages of easy and quick living tissue decimation and safety, achieving once success.
Description
This utility model relates to a kind of medical apparatus and instruments, the living tissue puncture needle of a kind of specifically extraction inside of human body focus.
At present clinically be used to extract the living tissue old-fashioned puncture needle of human body and often be difficult for successfully, not only manipulate difficulty, and increased misery, also increased the weight of financial burden accordingly to patient.
The purpose of this utility model provides a kind of easy for operation, extraction focus living tissue that both can be once successful, the double-deck puncture needle of the inner-rotary type of the drug-injection in treatment of can suiting the medicine to the illness again.
For achieving the above object, scheme of the present utility model is made up of auger hair style nook closing member and hollow needle, and its architectural feature is to establish a nook closing member in hollow needle, and the head of nook closing member is shaped on 3-7 circle screw type bit, and afterbody is shaped on wide-mouth.Nook closing member is hollow to communicate with spiral goove down, goes up to communicate with wide-mouth.Be positioned on the hollow needle wide-mouth outer rim and be shaped on the snap ring axle, on the axle snap ring is housed.On the needle handle of hollow needle, be shaped on adjustment screw.
The utility model has the advantages that novel structure, reasonable in design, easy to operate, safe and reliable, reduce patient's misery.
Be described further below in conjunction with accompanying drawing:
Puncture needle shown in the figure is to establish a nook closing member 3 in hollow needle 8, and the head of nook closing member is shaped on screw type bit 6, and afterbody is shaped on wide-mouth 2, and the wide-mouth outer wall is carved with mark " 11 " aims at drill bit cutting edge of a knife or a sword mouth near point 12.Be shaped on drawing liquid hole 5 on spiral drill flute top, nook closing member is hollow to communicate with spiral goove drawing liquid hole 5 down, goes up to communicate with wide-mouth 2.Be shaped on snap ring axle 1 on hollow needle wide-mouth 9, on the axle snap ring 10 be housed, snap ring heals up and locates to be carved with mark " 13 " aligning syringe needle cutting edge of a knife or a sword mouth near point, is provided with depth adjustable ring 7 on the needle handle of hollow needle, and adjustment screw 4 is housed on the adjustable ring.
During use, nook closing member is packed in the hollow needle, make its sealing non-loosening, drill bit cutting edge of a knife or a sword mouth is salty folded concordant consistent with the syringe needle cutting edge of a knife or a sword, nook closing member wide-mouth mark and the syringe needle snap ring mark that heals up is consistent, aims at syringe needle, nook closing member cutting edge of a knife or a sword mouth near point, regulates the pre-inserting needle degree of depth and thrusts affected part, clockwise direction rotation nook closing member drill bit 2-4 circle is transferred to nook closing member, gets in the drill bit spiral goove and stays thing to get final product biopsy.This utility model is made large, medium and small three series as required, is applicable to the living tissue puncture of various focuses, lump.
This utility model reduces the lesion tissue cell transfer because outer syringe needle is fixed, and it is simple and direct quick, safe and reliable to extract living tissue, can reach the raising one-time success rate.Meanwhile, utilize the examination of outer needle applicator to take out, can be used as a kind of compensatory device of drawing materials just in case run into " doing focus " when undesirable.In addition, but drug-injection in treatment also, and according to the sufferer concrete condition, injection is selected in decision, reduces the lesion tissue cell transfer, improves cure rate, does not increase patient's misery and do not need to puncture in addition again.
