Specific embodiment

The embodiment of technical solutions of the utility model is described in detail below in conjunction with accompanying drawing.Following examples are only For clearly illustrating the technical solution of the utility model, therefore example is only used as, and this practicality can not be limited with this New protection domain.

It should be noted that unless otherwise stated, technical term used in this application or scientific terminology should be this reality The ordinary meaning understood with new one of ordinary skill in the art.

In the description of the present application, it is to be understood that the term " side of the instruction such as " center ", " length ", " interior ", " axial direction " Position or position relationship are, based on orientation shown in the drawings or position relationship, to be for only for ease of description this utility model and simplification is retouched State, rather than indicate or imply indication device or element must have specific orientation, with specific azimuth configuration and operation, Therefore it is not intended that to restriction of the present utility model.

Embodiment：

Small needle knife, as shown in figure 1, including the needle body 1 of strip, one end of the needle body 1 is provided with broken skin knife 2, the broken skin Knife 2 includes the blade formed by least one inclined-plane, and the blade is vertical with the length direction of the needle body, and the other end of the needle body sets There is hoe scaler 3, the hoe scaler 3 includes an end face vertical with the needle body and the tangent plane intersected with the end slope, Can be along the Anti-slip cover 4 of the length direction of needle body slip in upper being also arranged with of the needle body.

When the small needle knife that the present embodiment is provided is used, operator holds Anti-slip cover, first skin is entered with the blade of broken skin knife Row broken skin, after broken skin, hoe scaler is stretched in skin in the way of its tangent plane and contact tissue from broken skin, peels off harmful or disease Become tissue.Hoe scaler forms angle cutter head of the end for tack, ensure that on the premise of nerve is not cut, can be rapidly Peel off harmful or pathological tissues.Anti-slip cover can slide along the length direction of the needle body, facilitate operator in operation according to concrete Situation or custom adjust the anti-skidding distance for being set to two ends, can be used for treating from epidermis apart from each different positions.The little pin Knife is simple to operate quick, and the time calculates in seconds.The small needle knife is safer, not with sharp tip, can be used for treatment nerve Pathological tissues near neighbouring position or stripping is neural, it is not easy to cut-out nerve.The needle knife therapy scope is wide, can treat many Plant intractable pain, internal medicine disease, such as gynaecopathia, various pain of neck, shoulder, waist and leg, facial spasm, facial paralysis, ankylosing spondylitises, lumbar vertebra vertebra Body is slipped, femur head necrosiss, talalgia, dizziness, headache, trigeminal neuralgia, synovitis etc..

In order that the small needle knife operation is simpler quick, the needle body generally diameter range is 0.6 millimeter~1.2 The cylinder of millimeter, differing needles body structure is adapted to the position of difference sufferer crowd and the adhesion degree of pathological tissues.Diameter of needle body More pinprick is less.The needle body of minor diameter is adapted to small area, minor illness height or is afraid of the sufferer crowd of pain.The needle body of major diameter is fitted Combination of syndromes variable area is big or sufferer crowd of adhesion time length.

The angle of the extended line on the inclined-plane and needle body axis direction of the broken skin knife-in-knife sword is 175 ° ± 10 ° so that Broken skin knife is sharper, during with the broken skin knife broken skin, can reduce the pain of sufferer.

It is 2 millimeters that the inclined-plane of the broken skin knife-in-knife sword is mapped to the length of projection of the needle body on the cross section of blade ~8 millimeters, this embodies the gradient of broken skin knife-in-knife sword.By the projected length on the inclined-plane of blade, the diameter of the needle body and length The comprehensive gradient and sharpness for determining broken skin knife-in-knife sword of degree, the bigger blade of gradient is sharper, and sufferer is experienced when using Pain it is less.

The end face of the hoe scaler is the semicircle that radius is equal to needle body radius.Ensure that and shelled after skin is rapidly entered From pathological changes or adverse tissue.

The angle of the extended line on the tangent plane and needle body axis direction of the hoe scaler is 171 ° ± 10 °.The hoe scaler is cut The angle in face, more effectively realizes peeling off pathological tissues, and the destruction without causing nerve and normal structure such as will not be to god Jing causes cutting damage.Simultaneously the angle ensure that and entered faster from broken skin that reduce the pain of sufferer, doctor operates more Plus it is convenient.

It is 1 millimeter~3 that the tangent plane of the hoe scaler is mapped to the length of the projection in the plane vertical with hoe scaler end face Millimeter, the diameter of the projected length and the needle body, length are directly proportional.

The length of the needle body is 90 millimeters~175 millimeters.Doctor can be according to the different parts of sufferer or the custom of doctor From the needle body model of different length.

Anti-slip veins are additionally provided with the Anti-slip cover.Anti-slip veins can increase the frictional force of operator's hand and small needle knife, rise Anti-skidding effect is arrived.The Anti-slip cover is made up of elastomeric material.Elastomeric material is common materials, and low cost is lightweight.

Finally it should be noted that：Various embodiments above is only illustrating the technical solution of the utility model, rather than it is limited System；Although being described in detail to this utility model with reference to foregoing embodiments, one of ordinary skill in the art should Understand：It still can modify to the technical scheme described in foregoing embodiments, either to which part or whole Technical characteristic carries out equivalent；And these are changed or are replaced, the essence for not making appropriate technical solution departs from this practicality newly The scope of each embodiment technical scheme of type, it all should cover in the middle of the scope of claim of the present utility model and description.
