Guide wire pusher

Abstract

The invention discloses a guide wire pusher which comprises an upper casing, a lower casing and a pushing wheel, wherein an upper half guide channel and an upper half pushing wheel groove are formed in the upper casing, and a lower half guide channel corresponding to the upper half guide channel and a lower half push wheel groove are formed in the lower casing; and after the upper casing and the lower casing are clamped, a complete guide wire guide channel is formed by the upper half guide channel and the lower half guide channel, a push wheel accommodating groove is formed by the upper half push wheel groove and the lower half push wheel groove, the push wheel is placed in the push wheel accommodating groove, and a guide wire protection cap is arranged at the near end of the guide wire guide channel. Scale marks are arranged on the surface of the guide wire guide channel, so that a medical worker can conveniently confirm the length of the guide wire; and the upper casing, the lower casing and the push wheel are subjected to injection molding, the machining process is simplified, and the production cost is reduced.

Description

technical field [0001] The invention relates to a medical device, in particular to a guide wire pusher, which is applied in the field of intervention. Background technique [0002] Interventional therapy is an emerging treatment method between surgery and internal medicine, including endovascular intervention and non-vascular interventional therapy. It is a minimally invasive treatment method that treats the lesion locally under guidance. At present, during clinical interventional treatment, a guide wire is usually used to assist the catheter to insert the lesion of the patient. During the process of placing the guide wire, the guide wire is successfully delivered to the required position with the help of a guide wire pusher. However, some guide wires do not have length marks or the distance between length marks is very large, so they can only be estimated based on their own experience, which brings inconvenience to medical staff to a certain extent. [0003] At present, t...
