Description

Technical Field

[0001] The utility model relates to the field of medical devices, in particular to a high-strength medical braided guide wire fixing device. Background Art

[0002] Medical braided guidewire is a medical interventional technology that can be used to treat cardiovascular diseases, cerebrovascular diseases, tumor diseases, ophthalmic diseases, gynecological diseases, etc. When using braided guidewires to treat patients clinically, doctors are required to hold the braided guidewires for introduction. In order to facilitate doctors to fix the braided guidewires, fixing devices are generally used to fix the braided guidewires, but existing fixing devices have certain inconveniences when used.

[0003] A medical guide wire auxiliary clamping device is disclosed in the Chinese utility model patent application number: CN202122210910.0. When the second threaded rod is rotated by the adjusting block, the two moving blocks can move relative to each other. The connecting rod can be used to change the height of the fixed plate while the moving block moves, and then the height of the guide wire clamped on the clamping mechanism is adjusted to make the guide wire at a suitable height, which is convenient for surgical personnel to insert and rotate the guide wire. There is no need for auxiliary personnel to hold the guide wire for a long time, which reduces surgical pressure and ensures the normal progress of the operation. A placement slot and a limit plate are provided, and the bottom wall of the placement slot and the lower end of the limit plate are both smooth arc-shaped surfaces. When the guide wire is limited and clamped, the guide wire is prevented from moving up and down, and it is convenient for the guide wire to be pulled left and right and rotated. However, the clamping device is not convenient for controlling the retraction and release of the guide wire when in use, and cannot quickly fix and release the guide wire, cannot accurately locate the length of the guide wire, and the clamping device cannot clean and disinfect the guide wire when in use, and cannot guarantee the use effect of the guide wire. For this reason, we propose a high-strength medical braided guide wire fixing device. Utility Model Content
