Fibrovascular scissors with syringe

Abstract

The invention belongs to the technical field of medical supplies, relates to medical treatment instruments, in particular to a pair of fibrovascular scissors with a syringe. During a vascular surgical operation, for small vessels with small diameters, bad vessel filling and thickened vessel walls, contralateral walls are easy to injure, vascular incision and anastomosis are difficult and surgical operation risks are increased by using the fibrovascular scissors. A syringe cavity is formed in a scissor body on one side of the fibrovascular scissors, a syringe piston is loaded in the syringe cavity and a syringe piston handle is exposed to the opening of the scissor body; a syringe needle is embedded in a needle hole communicated with the end part of the syringe cavity, and the needle hole is positioned in the other side of a scissor blade body; the syringe needle at the scissor sharp part is longer than the scissor blade; during the operation, the guide needle is positioned before the scissors, so that the fact that the fibrovascular scissors are positioned in the vessel before vessel shearing is guaranteed, the vessel filling is ensured and the clarity of a partial operative field is kept during the process of shearing the vessel.

Description

technical field [0001] The invention relates to an auxiliary medical treatment device, which belongs to the technical field of medical supplies, in particular to a fibrovascular scissors with a syringe. Background technique [0002] Fibrovascular scissors are mainly used for incision of arteries and veins during vascular surgery to facilitate butt anastomosis between blood vessels. In the existing operation, the syringe is first punctured, after injecting a small amount of heparin saline, the syringe is withdrawn, and the fiber vessel scissors are used to puncture for the second time, and the blood vessels are cut. Large and medium arteries and veins have large lumens and thick walls, so they are relatively easy to cut with fibrovascular scissors, and it is not easy to injure the contralateral vessel wall. However, for small blood vessels with small diameter, poor filling of the vascular lumen, and thickened vascular wall, fibrovascular scissors are easy to damage the oppos...

AI Technical Summary

Problems solved by technology

However, for small blood vessels with small diameter, poor vascular cavity filling, and thickened vascular wall, fibrovascular scissors are easy to injure the opposite side wall, and it is not easy to cut and anastomose the blood vessels, which increases the risk of vascular surgery and is harmful to the operator. It is said that the technical requirements of the incision are particularly strict, and the repair of the damaged vessel wall will increase the scar tissue of the intima wall of the vessel, which may form scars and stenosis in the local area. risk, increasing adverse risk to the patient's prognosis
