Detailed Description

The present utility model will be further described in detail with reference to the following examples, which are only for the purpose of illustrating the utility model and are not to be construed as limiting the scope of the utility model.

According to the figures 1, 2, 3 and 4, this embodiment provides a sharp needle for interventional puncture, which comprises a needle head 1, a needle tube 2 connected with the needle head 1 and an injection push rod 3 at the rear part of the needle tube 2, wherein a scale mark 4 is arranged on the outer wall of the needle head 1, a first pivot 5 is slidably arranged on the outer wall of the needle head 1, a second pivot is arranged on the outer wall of the needle tube 2, the second pivot comprises a sleeve ring 6, a sliding groove 7 and a pressing piece 8, the sliding groove 7 is arranged on the outer wall of the needle tube 2, the sleeve ring 6 is rotatably arranged on the sliding groove 7, the sleeve ring 6 is slidably connected with the sliding groove 7, the pressing piece 8 is fixed on the outer wall of the sleeve ring 6, an adsorption component is arranged on the inner side of the pressing piece 8, when the sharp needle for interventional puncture is inserted into a human body, along with stretching into of syringe needle 1, first fulcrum 5 slides on syringe needle 1, thereby can clear syringe needle 1's depth of insertion through first fulcrum 5 cooperation scale mark 4, simultaneously when the injection of some inclination, first fulcrum 5 can be as the back-up point between syringe needle 1 and the skin, thereby the force that needs to exert in order to guarantee to stabilize when the reduction doctor of a small margin is handheld, simultaneously when carrying out the injection to some positions, say the nose, because high problem, doctor can laminate preforming 8 and face between this moment, thereby form the fulcrum, and promote needle tubing 2, inject syringe needle 1 inside the skin, reduce doctor's operating pressure by a wide margin, thereby alleviate the tired degree of its hand.

The pressing sheet 8 is arc-shaped sheet-shaped, the end part of the pressing sheet 8 is semi-arc-shaped, and the pressing sheet 8 is arranged into an arc shape so as to enable the pressing sheet 8 to be more attached to the face.

The preforming 8 is flexible steel sheet, the inboard of preforming 8 is equipped with the blotter, and the setting of flexible steel sheet has better ductility when making preforming 8 and facial laminating, and the setting of blotter is the comfort level when increasing preforming 8 and skin contact.

The adsorption component comprises sucking discs 9, a plurality of groups of sucking discs 9 are arranged on the inner side of the buffer pad, the sucking discs 9 are distributed at equal intervals, and the arrangement of the sucking discs 9 is used for guaranteeing the stability of the compression sheet 8 and the adsorption of the skin.

The first supporting point 5 is in an elliptic sphere shape, a line 10 is arranged on the inner wall of the elliptic sphere shape, a wire groove 11 is arranged on the outer wall of the needle head 1, the line 10 is clamped into the wire groove 11 and is in sliding connection with the wire groove 11, the first supporting point 5 is prevented from sliding off the needle tube 2 through the arrangement of the wire groove 11 and the line 10, and compared with other shapes, the elliptic sphere-shaped structure of the first supporting point 5 is more suitable for being contacted with skin to form a supporting point.

This intervene puncture with sharp needle when using, through arc preforming 8 and skin laminating, sucking disc 9 guarantees the absorption between preforming 8 and the skin simultaneously to form a stable fulcrum, support needle tubing 8 and syringe needle 1, inside needle head 1 inserts the skin through promoting needle tubing 2, the injection is accomplished to the rethread pushing injection push rod 3, simultaneously, at preforming 8 during the off-working, syringe needle 1 and skin slope contact, first fulcrum 5 becomes the fulcrum between syringe needle 1 and the skin this moment, forms the support, thereby alleviates injection personnel's operating pressure.

The foregoing has shown and described the basic principles, principal features and advantages of the utility model.
