A guide wire storage device

Abstract

The invention relates to the field of medical equipment, in particular to a guide wire storage device. The guide wire storage device comprises a stationary shaft, a supporting mechanism and a windingmechanism, the supporting mechanism is fixedly connected with the two ends of the stationary shaft, wherein the winding mechanism comprises a winding roller, a locking block, a handle and a buffer block, the winding roller is coaxially and fixedly arranged on the stationary shaft, the outer surface of the winding roller is provided with a helical guide groove, the buffer block is fixedly arrangedin the guide groove, and the buffer block is internally provided with a through hole allowing a guide wire to run through; the two opposite side walls in the guide groove are provided with sliding grooves, the two sides of the locking block are fixedly provided with limiting blocks sliding in the sliding grooves, and the locking block is in sliding contact with the inner wall of the guide groove;the locking block is internally provided with a mounting hole clamping a guide wire, and the mounting hole can be opposite to the through hole; the side, away from a transfer roller, of the locking block is provided with a threaded hole communicated with the mounting hole, the handle is in threaded connection with the threaded hole, and the end, close to the locking block, of the handle can abut against the inner surface of the mounting hole. The guide wire storage device can prevent the inner wall of a catheter from being damaged.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a guide wire storage device. Background technique [0002] A guide wire, also known as a guide wire or guide wire, is one of the main tools for percutaneous catheterization. The guide wire guides and supports the catheter, helps the catheter enter blood vessels and other cavities, and guides the catheter to reach the lesion smoothly. The guide wire is generally composed of inner and outer parts, and the outer layer is made of high-quality stainless steel wire wound on a spring lathe. The steel wire is required to be smooth, tough and elastic, and the winding must be even and tight, arranged in an orderly manner, and consistent in density. This kind of spring should be able to withstand repeated bending and not break under a certain force. [0003] During the clinical use of the guide wire and catheter, the catheter is inserted into the patient under the guidance an...

Problems solved by technology

[0003] During the clinical use of the guide wire and catheter, the catheter is inserted into the patient under the guidance and support of the guide wire, and then the guide wire in the catheter is pulled out. Generally, the medical staff pulls it manually, usually on the side. During the guide wire process, while the guide wire is wrapped around the finger, the guide wire is rotated during this process, and the end of the guide wire located in the catheter will rotate and tremble at the same time. The outer wall of the guide wire will contact the inner wall of the catheter, which will cause the catheter inner wall damage
