Guide wire conveying mechanism

Abstract

The invention discloses a guide wire conveying mechanism which comprises a guide wire fixing seat and a guide wire rotating mechanism arranged on the guide wire fixing seat. The guide wire rotating mechanism comprises a guide wire rotating wheel and a guide wire rotating driving mechanism for driving the guide wire rotating wheel to rotate, and the guide wire rotating wheel is provided with a guide wire opening groove extending from the side face to the axis and a guide wire fixing device for fixing a guide wire at the bottom of the guide wire opening groove. According to the guide wire conveying mechanism, the guide wire rotating wheel is provided with the guide wire opening groove extending from the side face to the axis, namely, the guide wire can be directly installed at an axis position of the guide wire rotating wheel through the guide wire opening groove, and compared with the mode that in the prior art, the guide wire penetrates from one end, installation is simpler; and more importantly, the guide wire can further be directly separated from the guide wire opening groove, and the problem that in the prior art, the guide wire needs to be pulled out of a body in advance for guide wire separating due to separating can only be performed from one end is effectively solved.

Description

technical field [0001] The invention relates to the field of intervention technology, in particular to a guide wire delivery mechanism. Background technique [0002] Interventional technology is a minimally invasive treatment using modern high-tech means. Under the guidance of medical images, special catheters, guide wires and other precision instruments are introduced into the human body for diagnosis and local treatment of lesions in the body. Most of the interventional treatment items are carried out in the blood vessels. It does not require surgery. It only needs to make small diameter wounds on the blood vessels and skin, and insert special catheters and guide wires into the blood vessels. Treatment or medical treatment of diseases with poor efficacy, such as tumors, hemangiomas, various hemorrhages, cerebrovascular malformations, etc. [0003] With certain types of disease, such as hardening of the arteries, images of a person's heart may show blockage in one or more ...

Problems solved by technology

In the guide wire catheter used in peripheral vascular intervention, the guide wire needs to be inserted from the tail of the catheter, and this patent cannot solve this problem

Patent 2017208089972 discloses an interventional surgery robot from the end and its mobile platform can solve the problem of cooperation between the catheter and the guide wire, but the structure of this patent is complicated, and it is inconvenient to install the guide wire and catheter. Guidewire and catheter are withdrawn from the patient
