Description

Technical Field

[0001] The utility model relates to the technical field of cardiovascular puncture, in particular to a cardiovascular puncture auxiliary device. Background Art

[0002] Cardiovascular puncture is a commonly used medical technology that punctures the cardiovascular system to diagnose, treat or rescue patients. This technology is usually used in the examination of cardiovascular diseases, cardiac function assessment, hemodynamic monitoring and emergency treatment of acute cardiovascular events. Common methods of cardiovascular puncture include arterial puncture: usually puncture at the radial artery, femoral artery or brachial artery to obtain arterial blood samples, monitor blood pressure and hemodynamic indicators, and perform interventional treatments such as arterial angiography and thrombolysis; venous puncture: suitable for large veins such as the cubital vein and femoral vein, mainly used for collecting venous blood samples, infusion, medication and installation of central venous catheters.

[0003] Cardiovascular puncture assist devices play an increasingly important role in modern medical practice. With their unique advantages, these devices provide more accurate, safe and efficient solutions for cardiovascular puncture surgery. Cardiovascular puncture assist devices have the function of guiding puncture. By adopting advanced positioning technology and image guidance systems, these devices can accurately guide the puncture needle to the target position and reduce errors during the operation, which helps to improve the accuracy and success rate of the operation and reduce the pain and complications of patients. The design of cardiovascular puncture assist devices can avoid accidental injury to surrounding tissues to the greatest extent. The safety protection mechanism in the device can ensure that the puncture needle will not damage surrounding blood vessels, nerves or other important tissues before reaching the target position, which helps to reduce surgical risks and improve patient safety.

[0004] In order to facilitate the adjustment of the tilt angle of the clamped puncture needle, the utility model patent CN220967379U discloses a cardiovascular puncture auxiliary device, including a support column and a fixed frame. The fixed frame is provided with a sphere on the side, and one end of the support column is provided with a spherical groove. The sphere is movably fitted in the spherical groove. The bottom end of the support column is threaded with a positioning handle bolt for fixing the sphere. The device is convenient for adapting to the tilted puncture needle fixation by setting a fixed frame to allow the sphere to move in the spherical groove on the support column, and is convenient for positioning the position of the sphere after movement by the positioning handle bolt. However, the device cannot simultaneously disinfect the puncture cannula passing through, and the front end of the entry cannot be effectively tilted and supported, which is easy to cause the tube wall to bend, etc., affecting the use of the puncture cannula.
