Coronary intervention guidewire fixing device

Abstract

The invention discloses a coronary intervention guidewire fixing device. The device is composed of a balloon fixing device and a guidewire fixing device, the balloon fixing device and the guidewire fixing device are connected through two sliding tubes, balloon fixing bolts in the device are connected with a balloon fixing cavity and a balloon fixing stabilizing tube, and a sliding tube stabilizeris connected with the sliding tubes. A heparin salt water release ring is connected with a heparin salt water drainage tube, a tube cavity is communicated internally, after an injector is inserted into an injector connecting port to inject heparin salt water, the heparin salt water is evenly distributed in a balloon tube cavity through the drainage tube and the release ring, and ultra-smooth sliding heads of the sliding tubes are connected with sliding grooves and can slide forwards and backwards in the sliding grooves. A guidewire fixator can fix a guidewire in a guidewire fixing cavity, andthe tightness of guidewire fixing is completed by rotating a guidewire fixing knob to drive a guidewire fixing bolt. The problem that in the interventional operation process, the guidewire is prone tofalling off and even stays in the coronary artery is solved, and the guidewire is stable and not prone to falling off through use of the coronary intervention guidewire fixing device.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a coronary intervention guide wire fixing device. Background technique [0002] During the current coronary intervention operation, the operator and assistants need to frequently exchange the guide wire, catheter and balloon, but in the process of frequent exchange of the balloon, guide wire, catheter and coronary stent, It is very easy for the guide wire to fall off or even stay, which makes the operation process unable to proceed smoothly. Therefore, it is often necessary for the operator to change hands continuously or ask an assistant to assist in the operation, which is very inconvenient and seriously affects the smooth progress of coronary interventional surgery. Contents of the invention [0003] The purpose of the present invention is to solve the current lack of a device that can effectively prevent the guide wire from falling off or even stay in the coronary artery, and...
