Brachial vein puncture sheath for simplifying TAVR surgery, puncture assembly and use method of brachial vein puncture sheath

Abstract

The invention discloses a brachial vein puncture sheath for simplifying TAVR surgery, a puncture assembly and a using method thereof.The puncture sheath comprises a puncture sheath tube and a puncture sheath base connected to the far end of the puncture sheath tube, and an inner cavity penetrating through the two ends of the puncture sheath base and communicating with the puncture sheath tube is formed in the puncture sheath base; a temporary pacemaker imbedding channel is formed in the side end of an inner cavity of the puncture sheath base, a central venous pressure monitoring pipeline, a transfusion pipeline and a standby pipeline which are communicated with the inner cavity of the puncture sheath base are connected to the side portion of the puncture sheath base in the circumferential direction, and a hemostasis valve is arranged in the inner cavity of the puncture sheath base. The far ends of the central venous pressure monitoring pipeline, the infusion pipeline and the standby pipeline are all provided with three-way connectors. Preoperative blood vessel path preparation work is simplified, blood vessel paths are integrated, blood vessel path puncture is reduced, postoperative nursing is facilitated, and the possibility of postoperative blood vessel path infection is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a brachial vein puncture sheath for simplifying TAVR operations, a puncture assembly and a use method thereof. Background technique [0002] Aortic stenosis (Aortic Stenosis, AS) is a common heart valve disease in the elderly, and its incidence increases with age. The incidence of AS is about 2% in people ≥65 years old and about 4% in people ≥85 years old. [0003] Transcatheter Aortic Valve Replacement (TAVR) is an emerging minimally invasive valve replacement technology in the past ten years. Artificial aortic valve replacement has the advantages of no thoracotomy, low risk, simple operation, less trauma, With the advantages of fast recovery and fewer complications, it is especially suitable for patients with surgical contraindications or high-risk surgical operations. [0004] TAVR surgery takes about 2 hours from the preoperative preparation to the end of the operat...

Problems solved by technology

Among them, one vascular path for monitoring central venous pressure, one vascular path for infusion access, one temporary pacing electrode vascular path, and one backup vascular path need to be established before operation. The establishment of vascular paths for different surgical requirements will increase the preoperative preparation time. , Excessive vascular puncture will bring cumbersome nursing work for postoperative vascular access care. At the same time, excessive vascular puncture may increase the possibility of vascular infection
