Guide wire delivery device for vascular intervention surgical robot

Abstract

The invention discloses a guide wire delivery device for a vascular interventional surgical robot. The guide wire delivery device comprises a chassis; the draw-off godet comprises a reel and is rotatably mounted on the chassis, and a connecting hole is formed in the center of the draw-off godet and used for being connected with a draw-off godet rotation driving shaft; the guide wire is wound on the reel, and the tail end of the guide wire is fixed on the wire guide disc through a guide wire end part fixing device; the guide wire pressing device is used for pressing the guide wire in the radial direction to prevent the guide wire from loosing and winding; the guide wire delivery device is provided with a guide wire channel, and the free end of the guide wire extends out of the guide wire delivery device through the guide wire channel. In an assembly state, the connecting hole of the draw-off godet is connected with the draw-off godet rotation driving shaft, the draw-off godet is driven by the draw-off godet rotation driving shaft to rotate relative to the base plate, and when the draw-off godet rotates in one direction, a guide wire is loosened from the reel and delivered forwards through the guide wire channel. And when the yarn guide disc rotates in the other direction, the guide yarn is wound on the reel and withdrawn through the yarn guide channel.

Description

technical field [0001] The present invention relates to the technical field of medical devices, in particular to a guide wire delivery device for a vascular interventional robot to realize guide wire delivery. Background technique [0002] Minimally invasive vascular interventional surgery is the basic method for the diagnosis and treatment of cardiovascular and cerebrovascular diseases. Most of the current vascular disease diagnosis and vascular reconstruction operations require the help of this technology. The operation of the guide wire is one of the core contents of minimally invasive vascular interventional surgery, which determines the quality of the operation. Currently, interventional doctors use digital silhouette angiography (DSA) to manually position the guide wire in the patient's blood vessel. The positioning operation of the guide wire using a robot device is conducive to improving the accuracy and stability of the positioning operation, liberating medical sta...

Problems solved by technology

[0006] The guide wire delivery of traditional vascular interventional surgery robots has the following problems: due to the ultra-smooth loach coating on the surface of the guide wire, the guide wire is easy to slide when encountering resistance, resulting in a decrease in the accuracy of guide wire delivery; the guide wire delivery device The delivery effect is unstable; and the aseptic environment is not completely achieved
