Problems solved by technology

Therefore, the continuous bleeding in the artificial blood vessel during the operation will not only affect the surgical field of view, increase the difficulty of the operation, but also cause unnecessary blood loss to the patient. Therefore, it is necessary to invent a vascular puncture sheath that can not only operate normally but also effectively block blood.

Embodiment Construction

[0010] As shown in the figure, the vascular puncture occlusion sheath with balloon of the present invention comprises a sheath tube 1, an infusion tube 2 and a sheath handle 5, and is additionally provided with a balloon 3, a balloon inflation tube 4, a balloon 3 and a balloon The inflatable tube 4 communicates with the infusion tube 2 and the sheath tube 1 . The infusion tube 2 and the balloon inflation tube 4 are two independent pipelines leading out from the sheath handle 5 . The balloon is located above the end of the sheath tube 1, and it can be more than 5mm from the end. If it is set in the middle of the sheath tube, it will not affect the operation function of the sheath tube; The balloon communicates with the balloon inflation tube 4, and connects with the Y valve tube outside the sheath handle (independent passage), which does not affect the independent use of the vascular puncture sheath. The injection volume can be freely adjusted and controlled through the balloon...

Abstract

A blood vessel puncture plugging sheath with a balloon comprises a sheath tube 1), a transfusion tube (2) and a sheath handle (5) and is further provided with the balloon (3) and a balloon inflating tube (4). The balloon (3) is communicated with the balloon inflating tube (4) and arranged on the periphery of the sheath tube (1), the transfusion tube (2) and the balloon inflating tube (4) are parallelly arranged in the sheath tube (1), the transfusion tube is communicated with the sheath tube, and the transfusion tube and the balloon inflating tube are two independent tubes and are led out from the sheath handle. The blood vessel puncture plugging sheath with the balloon capable of being filled with liquid (gas) is used as a surgical instrument used for surgical operation on artificial blood vessels and the like, and simultaneously has a good visual field and a good hemostasis effect, the sheath tube not only is used as a normal surgical instrument (for transfusion and the like) in the field, but also can be used for hemostasis, the hemostasis effect is good, and blood loss of a patient in surgery can be greatly reduced. The blood vessel puncture plugging sheath is particularly applicable to hemostasis during artificial blood vessel surgery.

Description

technical field [0001] The invention relates to a surgical instrument for artificial blood vessel bypass surgery. Background technique [0002] Artificial vascular bypass surgery is one of the main methods for the treatment of peripheral arterial occlusive disease, and it is widely used clinically. With the progress of the patient's own arterial disease and the existing defects of the artificial blood vessel, more and more occlusive diseases occur in the body of the graft vessel and the proximal and distal ends of the anastomotic stoma, including the stenosis and occlusion of the own artery and the anastomotic stoma. Vascular intimal hyperplasia, thrombosis, etc. At this time, it is often necessary to cut the body of the artificial blood vessel, and to reconstruct the blood supply of the affected limb through methods such as Fogarty catheter thrombectomy and balloon expansion stent. [0003] When operating on an incised artificial blood vessel, the traditional blocking met...
