Vascular sheath hemostasis valve and medical instrument

Abstract

The present disclosure relates to a vascular sheath hemostasis valve and a medical instrument. The vascular sheath hemostasis valve is used for allowing a vascular sheath to be inserted and to pass through, and comprises a head end, a sleeve and a torsion assembly which are sequentially arranged; a hemostatic film tube is arranged in the sleeve; the head end is fixedly connected to the sleeve; the distal end of the hemostatic film tube is fixed to the joint of the sleeve and the head end; the proximal end of the hemostatic film tube is connected to the torsion assembly; the torsion assembly can rotate relative to the sleeve and is used for driving the hemostatic film tube to tighten and wrap or loosen and release the vascular sheath. According to the vascular sheath hemostasis valve in the present disclosure, an inner sheath tube or a catheter-type instrument of the vascular sheath can smoothly pass through the hemostasis valve, large hoop pressure is generated on the instrument, and the hemostatic effect is guaranteed.
