Abstract

The invention relates to the technical field of human body vascular stents. The invention discloses a device capable of automatically inserting a needle head and ensuring no deviation of a guide wirein a catheter. The device comprises an vascular stent guiding-in device main body. A movable needle tube is inserted into the inner wall of the left side of the vascular stent guiding-in device main body; a straight gear is fixedly mounted at the bottom of the movable needle tube; a cylindrical gear is in engaged transmission with the bottom of the straight gear; a transmission mechanism is in meshing transmission with the bottom of the cylindrical gear, a disposable needle head is inserted into the left side of the movable needle tube, a sheath tube is fixedly connected to the right side of the disposable needle head, a catheter box body is fixedly mounted at the top of the vascular stent guiding-in device main body, and a catheter outlet through hole is formed in the right side of the catheter box body. The transmission mechanism drives the cylindrical gear, the cylindrical gear drives the straight gear to move, the movable needle tube is pushed out, the disposable needle head penetrates into a human body, and the effects of automatically penetrating the needle head and better mastering the penetration depth of the needle head are achieved.

Description

technical field [0001] The invention relates to the technical field of human blood vessel stents, in particular to a device for automatically inserting a needle and ensuring that a guide wire inside a catheter does not move out of position. Background technique [0002] At present, vascular stent is the most effective way to treat cardiovascular diseases. Its specific process is to insert a needle into the patient's artery first, connect the sheath to the needle, guide the catheter to the cardiovascular place through the sheath, and then The vascular stent is transported to the blockage of the blood vessel through the catheter, and the blocked blood vessel is propped up by the air bag inside the vascular stent, and then the gas in the air bag is released to take out the air bag. At this time, the vascular stent is attached to the inner wall of the blood vessel. In addition, the stent The interventional method has the advantages of less trauma, fewer complications, and better...
