Abstract
The invention relates to the technical field of medical apparatus and instruments, and in particular relates to a syringe needle which is characterized in that the inner wall of the syringe needle is of a concave-convex rough surface structure. The syringe needle has the beneficial effects that the structure of the inner wall of the syringe needle is changed, under B-ultrasonic localization, a needle part of a puncture needle enters the lump part, and the concave-convex rough surface structure of the inner wall of the needle part enables the needle part to have lateral shear force in the rotation process through multi-direction lifting and inserting; in the withdrawing of the needle, the residual rate of the sucked cells on the inner wall of the needle part can be improved, so that enough lesion cells can be sucked, and even more the lesion cells are divided from the root and completely sucked; an operator does not need to pull a needle pintle by hand continuously, and the negative pressure inside a needle tube can be effectively controlled under the coordinated positioning of a baffle and a gap, so that the sucking success rate can be improved, a satisfactory smear is prepared, and the lesion nature is judged.
Description
Technical field
The present invention relates to technical field of medical instruments, specifically refer to a kind of syringe needle.
Background technology
Cytolgical examination successfully it is crucial that draw enough sick cells, enough negative pressure of having in being accurately positioned when generally depending on puncture, needle tubing and the relatively high residue amount of residual cell in needle tubing after extracting needle tubing out.
At present, domestic commonly used ordinary syringe does, as fine needle aspiration, absorption affected area cell, the device that biopsy detects, its advantage is painful little, easy and simple to handle, but there is following defect: 1, poor stability during operation, position inaccurate for the little lump of body surface and intraperitoneal lump, when repeatedly carrying slotting, it is easy to damage surrounding organ or tissue; 2, operator is needed to fix the skin of site of puncture with a hands, another hands carries out having to last for tractive pintle from the action of tractive pintle in needle tubing, operation effort, and operator, owing to being unable to maintain that bigger negative pressure in needle tubing, thus carry slotting, draw process is inconvenient; 3, affecting diagnostic reliability, when lump quality is harder, the needle tubing inner cell residual quantity of extraction is low, undersampling, makes cytolgical examination cannot draw reliable diagnosis.
Application number is " 201020199845.5 ", Authorization Notice No. is that " CN201675967U ", name are called that the Chinese utility model patent of " a kind of Novel tumor tissue sampling needle " discloses a kind of sampling probe, including syringe needle, needle tubing and piston, the sidewall of described syringe needle is distributed multiple circular pin hole, during use, syringe needle is thrust lump center, pull piston to draw tumor tissues, then take out and can do cytolgical examination. This invention has the disadvantage that: 1, on this syringe needle, duct is more, and single hole suction pressure is less, and swabbing pressure disperses, it is impossible to be drawn into the cell of q.s; 2, the precise positioning ability of less tumor tissues is poor, it is easy to aspirate the other tissue of a large amount of tumor or normal structure, affect diagnostic reliability; 3, add the incidence rate of needle track implantation, bring harm to patient.
Application number is " 201120503372.8 ", Authorization Notice No. is that " CN202426558U ", name are called that the Chinese utility model patent of " tissue examination sampling syringe needle " discloses a kind of sampling probe, needle stand including needle body and needle body afterbody, needle body front end is the needle point with angle, needle body extends a gap at needle point angle place to needle body defence line, and the edge of gap is provided with cutting edge. During concrete operations, this syringe needle is connected with syringe, this syringe needle is thrust in sampling tissue, by pulling syringe to produce negative pressure, sample and enter needle wall, rotating needle by gap on this syringe needle under the effect being organized in negative pressure, by the cutting edge at gap edge, sampling tissue is cut, cut is organized under suction function and is stranded in inside needle body, is extracted by syringe needle, and cut tissue stripping and slicing is taken out of therewith. This invention has the disadvantage that: 1, because extending a gap, therefore the precise positioning ability of relatively tubercle soma is poor, it is possible to the non-tumor tissue of cutout, affects diagnostic reliability; 2, " linearly aspirating cutting " is become from " point is taken out ", it is possible to accidentally injure the normal structure around tumor body, add the incidence rate of complication; 3, original closo needle head structure is changed, and mechanical strength declines, and adds the risk that broken needle is detained.
Application number is " 95225718.1 ", Authorization Notice No. is that " CN2243268Y ", name are called that the Chinese utility model patent of " inner rotating puncture needle for living tissue of two layers " discloses a kind of puncture needle, it is made up of auger hair style nook closing member and hollow boring bit, nook closing member it is provided with in hollow needle, the head of nook closing member is provided with screw type bit, drawing liquid hole it is provided with in spiral drill flute, communicating with spiral goove under nook closing member is hollow, the head of described nook closing member has 3��7 circle spiral gooves. During use, nook closing member loads in hollow needle, it is made to seal non-loosening, drill bit cutting edge of a knife or a sword mouth is overlapping concordant consistent with syringe needle sealing, the nook closing member wide-mouth mark mark that heals up with syringe needle snap ring is consistent, alignment syringe needle, nook closing member sealing near point, regulates pre-depth of needle and thrusts affected part, it is rotated clockwise nook closing member drill bit 2��4 circle and extracts nook closing member, drill bit spiral goove takes and stays thing to get final product biopsy. This utility model patent has the disadvantage that: auger hair style nook closing member is the nook closing member that head has 3��7 circle spiral gooves, and described spiral goove is positioned at outside nook closing member wall, only by coordinating could use with the hollow boring bit of inner wall smooth, the tissue of acquisition is few, and damages bigger to the overall structure of specimen.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, extraction cell specimen structure and form retain completely, have higher cell residue amount and meet the syringe needle for fine needle aspiration biopsy of later stage cell smear requirement.
