Abstract

The invention provides an edge face positioning device of a medical needle and belongs to the technical field of medical equipment. The edge face positioning device of the medical needle solves the technical problem that a needle tube deforms easily in a rotating process in the prior art. The edge face positioning device comprises a rack and rotating shafts, wherein the rotating shafts are connected with the rack in an inserted manner and can rotate freely and circumferentially; a manipulator for clamping a needle tube of a medical needle is fixed on each rotating shaft; each needle tube is positioned concentrically to each rotating shaft when the needle tube is clamped by each manipulator; and a rotating mechanism for driving the rotating shafts to rotate circumferentially is arranged between the rotating shafts and the rack. The edge face positioning device can adjust the rotation angle of each needle tube freely according to an actual condition and avoid deforming of the needle tubes.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and relates to a medical needle blade surface positioning device. Background technique [0002] In the medical device industry, medical needles are widely used, such as indwelling needles and venous needles. Currently used medical needles are made up of a needle head, a needle seat sheet and the like. Taking the venous needle as an example, the tip of the needle has a blade for puncturing. When using it, hold the needle seat fixed at the end of the needle tube so that the tip of the needle is close to the skin of the human body. When puncturing, hold the needle seat tightly. The cutting edge of the needle tip is obliquely upward, and the cutting edge of the needle tip is close to the skin vein, which is conducive to puncture. If the blade of the needle tip is obliquely facing downward, it is difficult to puncture. Therefore, when making medical needles, it is necessary to keep the cut...
