Description

Technical Field

[0001] The present invention relates to the technical field of medical guidewire storage, in particular to a guidewire storage mechanism for coronary heart disease interventional treatment. Background Art

[0002] Coronary heart disease (CHD) is a common cardiovascular disease with multiple causes. Atherosclerosis causes narrowing of the coronary artery lumen, leading to insufficient blood supply to the myocardium, which in turn triggers a series of clinical symptoms, including angina pectoris, myocardial infarction, heart failure, arrhythmias, and sudden death. Coronary interventional therapy is a method of diagnosis and treatment that uses cardiac catheterization to deliver diagnostic or therapeutic devices to the site of coronary artery disease. Balloon catheters, stents, and other devices are inserted percutaneously into the blood vessels, following the vascular pathway to the site of coronary artery stenosis or obstruction. The balloon is then used to dilate the stenosis, restore the vessel's internal diameter, and improve myocardial blood supply. If necessary, a stent is implanted to prop open the narrowed vessel, maintain patency, and prevent re-stenosis.

[0003] The guidewire used in coronary intervention is a key instrument in interventional procedures. During interventional therapy, the guidewire first enters the body through a vascular puncture and then follows the vascular pathway to the site of coronary artery lesions. It acts as a "track," guiding catheters, balloons, stents, and other interventional devices precisely to the lesion, ensuring smooth delivery of the therapeutic devices to the vessel requiring treatment. Guidewires used in coronary interventions typically require manual disinfection after use, but this manual process wastes time and resources. Summary of the Invention

[0009] Preferably, the outer wall of the baffle is fixedly connected to an electric slide rail, and the interior of the electric slide rail is slidably connected to a guide frame.

[0010] Preferably, an electric push rod is fixedly connected to the inside of the shell, and a slider 2 is fixedly connected to the output end of the electric push rod. The lower surface of the slider 2 is slidably connected to the inside of the shell, and the outer wall of the slider 2 is rotatably connected to the connecting rod 2.

[0015] Working principle: When using this mechanism, first adjust the spacing of the partitions, and then start the electric push rod to drive the slider 2 at the output end to slide. The slider 2 drives the connecting rod 2 to rotate. The connecting rod 2 can push the partition to slide, thereby changing the internal space of the shell, and setting different guide wires on the sleeves 1 on both sides and the sleeve 3 in the middle.

[0016] When the guide wire needs to be used or stored, the motor can be started to drive the screw rod at the output end to rotate, the screw rod drives the slider to slide, and the slider drives the spray pot to slide through the triangular plate, so that the nozzle can be aimed at the guide wire that needs to be stored, and the nozzle can perform the disinfection operation.

[0017] When the triangular plate slides, it pushes the triangular slider to slide, and the triangular slider drives the sliding frame to slide.

[0019] The present invention provides a guidewire storage mechanism for coronary interventional treatment. It has the following beneficial effects:

[0020] 1. The present invention can store multiple guide wires through the partition, and with the motor 1, the screw rod, the slider 1, the slide rod, the triangular plate, the spray bottle, and the nozzle, the guide wires can be disinfected when they are stored to prevent cross infection between different patients in subsequent use, and the guide wires in different positions can be disinfected separately, saving manpower and disinfection resources.

[0021] 2. In the present invention, the triangular plate pushes the triangular slider to slide, and the triangular slider drives the connecting rod to rotate through the sliding frame. The connecting rod pushes the opening and closing plate to rotate, so that the protective shell can be opened and closed. The protective shell can be used to protect the end of the guide wire, and when the opening and closing plate is opened, the nozzle corresponds to the guide wire in the corresponding position, which facilitates the disinfection work and does not cause motion interference.

[0022] 3. The present invention drives the slider 2 to slide through the electric push rod, and the slider 2 drives the partition to slide through the connecting rod 2. It can not only store multiple guide wires, but also adjust the storage space to adapt to different guide wires.

[0023] 4. In the present invention, further, through the cooperation between sleeve 1, spline shaft 1, sleeve 2, spline shaft 2, pulley 1, belt, pulley 2, spline shaft 3 and sleeve 3, the partition can be coordinated to slide, so that after the partition adjusts the distance, the guide wire can still be automatically reeled in by motor 2, thereby improving work efficiency.
