Description

technical field

[0001] The invention relates to a medical device, in particular to a sterile catheter sheath for assisting interventional therapy. Background technique

[0002] As an auxiliary guiding device for arteriovenous interventional surgery, the introducer sheath plays an important role in interventional therapy. In particular, the disposable sterile catheter sheath is an in vitro auxiliary consumable for cardiovascular interventional diagnosis and treatment. During PTCA angioplasty, the catheter sheath is left in the arterial vessel to establish a connection channel between the blood vessel and the outside world, so that it can be used for cardiovascular interventional angiography. , Cardiovascular dilation or placement of stents. The catheter sheath usually mainly includes a sheath tube seat and a sheath tube inserted into the sheath tube seat, wherein there is a large difference in the wall thickness of the front and rear parts of the sheath tube seat (the wall t...
