Description

Technical Field

[0001] The utility model relates to the field of vascular sheath groups, in particular to a novel vascular sheath group. Background Art

[0002] Vascular sheaths are designed for percutaneous insertion into the vascular system to introduce catheters, balloon catheters or stents for interventional diagnosis or treatment. Existing vascular sheaths lack the function of semi-automatic catheter fixation and delivery. Conventional catheter insertion is basically done by doctors manually inserting the needle, which is very inconvenient. If the fingers fail to hook the guide wire, there is a risk that the guide wire will slip into the blood vessel. Once the guide wire slips into the blood vessel, there is a possibility that the guide wire will be removed through interventional surgery, causing harm to the patient's body and increasing the patient's economic burden. Therefore, a new vascular sheath group is proposed. Utility Model Content
