Description

Technical Field

[0001] The present invention belongs to the technical field of surgical instruments, and in particular relates to a vascular intervention puncture device. Background Art

[0002] A vascular interventional puncture device is a medical device used for vascular interventional treatment. Its main purpose is to perform percutaneous vascular puncture for vascular interventional devices (such as catheters, guidewires, etc.) and establish a channel for subsequent diagnostic and treatment operations.

[0003] The radial artery is the most commonly used site for arterial puncture. The left radial artery is usually selected. The radial artery at the wrist is in the longitudinal groove between the radial flexor carpi tendon and the lower end of the radius. During puncture, the patient needs to lie supine on the bed with the left upper limb abducted on the arm rest, and gauze is used under the wrist to raise the wrist joint by 5-8CM.

[0004] During puncture, the existing puncture usually adopts the direct puncture method. After the puncture needle and the outer sleeve are inserted into the human artery, the puncture needle core is withdrawn, and the sleeve is left in the artery for subsequent insertion of the catheter, etc. When the needle core is withdrawn, blood will be sprayed out to make the hand support dirty. One end of the sleeve is inserted into the artery and the other end is bent outside the body, which affects the subsequent insertion of the catheter. When the sleeve is pulled out after the operation, it is currently necessary to perform local compression to stop bleeding for 3-5 minutes. The patient is not awake and needs to be compressed and stopped by a separate medical staff, which consumes manpower. In addition, when the patient shakes unconsciously during the operation, it will affect the puncture. Summary of the invention
