Anti-turning handle / Patent design CN209695247U

Designed for the beveled blade puncture needle, the position and direction of the inner needle can be locked by the handle to avoid the deflection of the inner needle during the puncture process, resulting in inconsistency between the bevel of the inner needle and the outer needle tube, which affects the puncture effect and even breaks the needle. This design reduces the burden on the doctor’s hands while ensuring the puncture effect. When unlocking, just tap the unlock button and rotate it counterclockwise in the direction of the arrow to open it. The operation is simple.


Ergonomic handle/perfect grip/design evolution

The contour of the handle is rounded and fully fits the palm of the hand. When holding with one hand, the needle body extends between the index finger and the middle finger. When the needle body is reciprocated left and right, the axis of the needle body can be relatively consistent with the handle, and the swing amplitude can be reduced. While improving the puncture efficiency, the puncture trauma is reduced and the patient’s pain is reduced.

Excellent smoothness of the surface

The needle body has special surface treatment to ensure the smoothness of the surface and reduce puncture resistance. The comparative measurement shows that the surface roughness of the self-made needle body is much higher than the requirement of Ra 0.2-0.6 for conventional products.

Excellent rigidity performance

The smaller the value, the better the performance. The comparison shows that the rigidity of the Chamfond needles of various specifications is significantly higher than the relevant standards, and not weaker than the foreign brand products, which fully meets the clinical needs.

High hardness needle body

In the normal state, the hardness of the stainless steel surface body can be divided into: soft state (>150 HV), semi-soft state (>200HV), hard state (>310HV), fully hard state (>370HV).
Higher needle body hardness, better deformation resistance, better wear resistance, and better overall strength.
