[0002] With the continuous popularization and application of intervention technology, clinical departments consider operation risk, patient comfort, shortening of hospitalization time and other issues when performing intervention surgery, and select appropriate vascular access. Radial artery is the best first choice for current cardiovascular intervention surgery access. A new radial artery puncture approach, i.e. distal radial artery about 5 cm further than radial artery puncture point, is easier to compress than radial artery and does not compress ulnar artery after surgery, with light postoperative hand swelling pain in patients. During the process of hepatic cancer perfusion chemotherapy intervention embolization surgery through distal radial artery, radial artery sheath tube is often indwelled near the wrist joint of the hand for postoperative treatment.

[0003] However, by the above-mentioned manner, the distal radial artery indwelling sheath tube is directly indwelled at the position near the wrist joint of the hand by puncture, which spans the wrist joint. When the wrist joint of the patient is accidentally moved after surgery, it may cause the sheath tube to fall off or be folded in the blood vessel. UTILITY MODEL CONTENT
