Tool for forming traumatic surface at edge of patency foramen ovale

Abstract

The invention discloses a tool for forming traumatic surface at the edge of patency foramen ovale. The tool comprises a catheter, a guidepost, a supporting rod, a knife, an operation mechanism and a guide wire, wherein the guidepost is arranged in the catheter in a sliding mode; the supporting rod is arranged in a third guide hole of the guidepost in a sliding mode, and a supporting head is arranged at the front end of the supporting rod; the guidepost is connected to the tail of the knife in a pin joint mode, and a tool bit is arranged on the head of the knife; the operation mechanism comprises an upper drawing wire and a lower drawing wire, the knife is connected to one end of the upper drawing wire and one end of the lower drawing wire, the other end of the upper drawing wire penetrates through a second guide hole of the guidepost and extends outward, and the other end of the lower drawing wire penetrates through a first guide hole of the guidepost and extends outward; the guidepost is connected to one end of the guide wire, and the other end of the guide wire extends outward along the catheter. The tool is flexible in using, convenient to operate and small in trauma.

Description

Technical field

[0001] The invention relates to the field of medical technology, in particular to a tool for forming a wound surface on the edge of an open foramen oval. Background technique

[0002] The foramen of the atrial septum in the heart is a normal channel for the fetus to maintain aerobic blood circulation before birth. When the fetus has spontaneous breathing, the foramen of the atrial septum should be closed naturally, but in the population, there is a considerable part of the foramen of the atrial septum. Permanently unclosed, patent foramen ovale is considered to be a cardiac factor that causes center and migraine. The treatment of this disease includes drug therapy, percutaneous catheterization and intuitive heart surgery, which requires manufacturing at the edge of the patent foramen ovale New wounds, and the application of drugs to accelerate the healing of the patent foramen ovale. In the process of making new wounds, homemade tools are usually used, which will ...
