Abstract
The utility model relates to the field of medical instruments, in particular to an arc-shaped-blade needle for medical treatment, cosmetology and health care. The needle comprises a needle handle, a hollow needle body connected with the needle handle, an arc-shaped blade located at the top end and a transition part between the arc-shaped blade and the needle body, wherein an included angle formed between a plane where the arc-shaped blade is and the cross section of the needle body ranges between 0 degree and 7 degrees; and the transition part is a folded-line-shaped cross section, an arc-shaped cross section or a waved cross section. Substantial cases prove that the usage of the arc-shaped-blade needle can be learned easily, the needle can be used conveniently, a large area of a paving towel is not required to be disinfected; the needle can be operated simply just like intramuscular injection; the clinical effective rate is one hundred percent, and needle-knife doctors like the needle very much; and a thorough needle-knife revolution is achieved.
Description
Technical field
This utility model relates to the medicine instrument field, relates in particular to a kind of arc sword pin for medical treatment, beauty treatment, health care.
Background technology
Can existing small needle knife be mainly by following several classes: one, be divided into traditional solid needle cutter, hollow needle knife for injection etc. according to injecting; Two, knife bar be traditional straight knife bar or bent shaped needle knife CN200720021682.X, the flat insertion needle knife CN200820096239.3 of " Z " shape, cutter head bar with the straight knife bar between the arcuated needle knife (CN200710168517.1) that is connected of circular arc etc.; Three, be divided into traditional " one " word pin cutter, syringe needle position to injection depression in the other direction according to the shape of blade, and the recessed sword injection needle (CN92208040.2), the flat pin handle of a knife front end that form the dome-shaped blade be the pin cutter head of arc, and the pin cutter head concave surface of described arc is sickle shaped small needle knife CN201120228681.9 with blade of the concave-bit needle knife (CN200620011997.1) of blade, inboard etc.Above all kinds of pin cutter respectively has advantage, but neither surgery and the ergonomics requirement that can meet the damaged tissue self-regeneration fully can not reach with less damage the maximum effect of loosening.And my multifunctional cord-embedding needle (CN201020257533.5) be though can avoid above deficiency, and it can be loosened by the pin cutter after sunkening cord mainly to sunken cord as main.My arc sword pin cutter (201210447675.1,201220590799.0) is though meet human surgery's requirement fully, and the transition part between its curved blade and needle body is the straight in cross-section of needle body, i.e. " V-type " structure in the plane.
Summary of the invention
The purpose of this utility model be to overcome deficiency of the prior art and provide a kind of simple in structure, easy to operate, reduce infection chance, simultaneously have acupuncture, loosen, blood-letting, injection, the arc sword pin that several functions is integrated such as sunken cord even, make it more to meet tissue injury repairing mechanism, can reduce cicatrix and produce, can reach with the damage of minimum the maximum effect of loosening.It is the supplementary invention of my arc sword pin cutter (201210447675.1,201220590799.0).
The purpose of this utility model is achieved in that
A kind of arc sword pin, transition part between the hollow needle body that comprises needle handle, is connected with needle handle, the curved blade on the top, curved blade and needle body, the cross section angle angle of the plane at described curved blade place and needle body is between 0 ° to 70 °, and described transition part is a broken line type cross section or arc section or wavy cross-section.
The joint on the plane at described transition part and curved blade place is right angle or arcuate structure.
Described needle handle is provided with pintle for pintle or its afterbody that can dock with the nipple of syringe.
Described needle body proximal part is solid.
Described needle body is " Z " shape or part is arc.
Described needle handle is a kind of in parcel shape, column, flat calabash shaped, wing, T-shaped, trapezoidal shape, mushroom, oblate column.
The outer cover of described needle handle and needle body is equipped with the sleeve pipe that syringe needle is shielded, and is provided with wedge between sleeve pipe and needle handle.
Compare with existing pin cutter technology, the advantage of this arc sword pin is as follows: 1, due to its hollow-core construction, be provided with the pintle that joins with syringe nipple as tail end, also have simultaneously injection and intervene operation guide sleeves bobbin function concurrently; 2, compare for conventional needle cutter or the concave-bit needle knife of " one " font with blade, because arc sword pin cuts and organizes not point-blank, the easier quick reparation of tissue and be not easy to produce adhesion, cicatrix meets more that the oneself of surgery's damaged tissue is perfect repairs requirement; 3, be both the 0.7mm diameter as example take needle body, particularity due to hollow needle body, the blade of this arc sword pin embodiment is actual is the composite construction of " arc " sword and " V " shape sword, the sword length of arc sword pin can reach 1.099mm, even can reach the effect of loosening of 2.198mm, thereby can reach with relatively minimum tissue injury the maximum effect of loosening; 4, due to the characteristics of curved blade, " ten " word cutting of the conventional needle cutter skill in using a kitchen knife in cookery and the cutting of " rice " word etc. thoroughly are reduced to the cutting of " one " word, having reduced tissue injury, reduced patient's misery, reduced doctor's operation treatment time, is the pin cutter revolution at a thorough end.A large amount of cases prove: the study of arc sword pin easily, and is easy to use, need not the large tracts of land sterile drape, and simple to operate as intramuscular injection, clinical effective rate is very firmly got liking of pin cutter doctor.
