Guiding wire coiled pipe device for precise positioning and guiding

Abstract

The invention discloses a guiding wire coiled pipe device for precise positioning and guiding in the field of medical apparatuses. The device includes a shell which is of a hollow structure and is made of transparent plastic, the shell is spliced by a left half shell body and a right half shell body, and a guiding passage which is spirally distributed and used for placing guiding wires is formed in an inner cavity of the shell; a guiding wire outlet end is also formed in the shell, a roller for conveying the guiding wires is rotatably installed at the guiding wire outlet end, a pointer is arranged on one side of the roller, precise ruler scales are arranged around the pointer, and a groove for placing the guiding wires is formed in the middle of the roller; a guiding head and a guiding platform used for fixing the guiding head are fixed to the portion, in front of a conveying wheel, of the guiding wire outlet end, the guiding head and the guiding platform are provided with guiding holes running through the guiding head and the guiding platform, and the guiding wires penetrate through the guiding holes slidably. The structure is simple, and positioning of the guiding wires is precise.

Description

technical field [0001] The invention relates to the field of medical appliances, in particular to a precise positioning guiding wire coil device. Background technique [0002] At present, interventional therapy is an emerging treatment method between surgery and internal medicine. It is the least invasive treatment method. A tiny channel is made on the blood vessel and skin, and the lesion is treated locally under the guidance of imaging equipment. Usually, a guide wire is used to assist the catheter to be inserted into the diseased part of the patient. During the process of placing the guide wire, the guide wire is successfully delivered to the required position by means of the guide wire pusher. The length of the guide wire, however, some guide wires have no length mark or the interval between the length marks is very large, so it can only be estimated according to one's own experience, which brings inconvenience to the medical staff to a certain extent.
