Percutaneous optical guidance vessel catheter device

Abstract

The invention discloses a percutaneous optical guidance vessel catheter device. The percutaneous optical guidance vessel catheter device comprises a vessel catheter, a miniature optical probe and a signal transmission wire, wherein the miniature optical probe is arranged at the front end of the signal transmission wire; the miniature optical probe and part of the signal transmission wire are movably arranged in the vessel catheter; the miniature optical probe can extend out of an opening in the front end of the vessel catheter or can retract into the opening in the front end of the vessel catheter. The percutaneous optical guidance multifunctional vessel catheter device provided by the invention has the functions of a catheter and a guide wire simultaneously, an X ray and a metal guide wire in a conventional interventional therapy do not need to be used, the device can be used at the bedside of a general ward, medical staff and patients are prevented from being injured by the X ray, the labor intensity of the medical staff is alleviated, the convenience of implementation is greatly improved, and the device is convenient to operate and popularize.

Description

technical field [0001] The invention relates to a blood vessel catheter device, in particular to a percutaneous optically guided blood vessel catheter device. Background technique [0002] Placement of catheters in blood vessels is a prerequisite for the diagnosis and treatment of many diseases. At present, the method of sending intravascular catheters into blood vessels in the body is to send the catheter to the target position under the guidance of X-ray perspective and metal guide wire. The disadvantage of the method is that it needs to be implemented in special places equipped with X-rays, such as catheterization labs, radiology departments, etc., which greatly limits the use of this method (such as bedside use), and medical personnel need to wear heavy lead clothing, which exposes In X-ray radiation, both medical staff and patients are harmed by radiation. Although there are a large number of studies on radiation protection in interventional radiology, these studies ca...

Problems solved by technology

[0004] However, when using OCT to diagnose, detect or treat blood vessels, it is necessary to place a vascular catheter in advance, and then send the ultrasonic probe or OCT optical probe into the target blood vessel position along the vascular catheter, while the traditional vascular catheter needs to be placed under X-ray fluoroscopy. Under the guidance of a guide wire, the vascular catheter is inserted, and its operation has special site requirements, and the medical staff is exposed to X-ray radiation and damage.
