[0002] A puncture device is a device used for cardiovascular puncture, usually for cardiovascular interventional treatment or examination in a clinical setting. A cardiovascular puncture device is used to puncture an artery or vein in order to insert a catheter or guidewire for interventional treatment or diagnostic examination. Once the vascular puncture is completed, the cardiovascular puncture device can help guide the catheter or guidewire to the target location. These catheters or guidewires can be used to deliver drugs, contrast agents, stents, etc., or to monitor physiological parameters such as blood pressure and blood oxygen saturation;
[0003] The cardiovascular puncture device inserts a catheter or guidewire into a blood vessel in the body through a needle, and then inserts a treatment device or performs other operations through the catheter. It can help medical staff to accurately and safely puncture and operate blood vessels during surgery or treatment. When the puncture needle of the cardiovascular puncture device passes through the skin and tissue and enters the blood vessel, the blood pressure in the blood vessel can easily cause the blood to overflow quickly when the puncture needle enters the blood vessel. In addition to the blood vessel, the surrounding tissue structure may also be damaged during the puncture process, which can easily cause local bleeding or fluid overflow. Therefore, we propose a puncture device that prevents fluid overflow. Utility Model Content

[0017] In specific implementation, according to Figure 1-Figure 3The cardiovascular puncture device inserts a catheter or a guide wire into a blood vessel in the body through a needle, and then inserts a treatment device or performs other operations through the catheter. When the puncture needle of the cardiovascular puncture device needs to pass through the skin and tissue and enter the blood vessel, first use the strap 201 to tie the placement plate 2 to the outside of the puncture site. The fixing pad 2011 is made of rubber material with a certain softness, so that the placement plate 2 is not easy to crush the skin. At this time, the limit screw 204 is rotated to make the limit screw 204 drive the gear 202 to rotate, and the gear 202 is meshed with the gear ring 203, so that the gear 202 drives the gear ring 203 to rotate, and the two gears 202 simultaneously drive the limit screw 204 to rotate, and the limit screw 204 and the limit screw 204 are engaged with each other.
