Interventional instrument conveying system

Abstract

The invention discloses an interventional instrument conveying system. The interventional instrument conveying system comprises a control handle, a sheath tube and a sheath core arranged in the sheath tube, wherein at least two developing points distributed in the axial direction of the sheath core are arranged at the far end of the sheath core. The interventional instrument conveying system is simple to operate and more precise in positioning. The developing points are positioned on the sheath core with a small diameter, so that the deviation of the observed developing points from actual positions caused by observation angles can hardly occur, and the positioning is simpler and more accurate during operation. Besides, the cost is low, three gold sheets do not need to be sewn on each interventional instrument as the developing points, and the developing points are arranged on the interventional instrument conveying system and can be repeatedly utilized. The more important is that the risk is low, the gold sheets used as the developing points do not need to be sewn on the interventional instrument, and the secondary injury caused by falling of the gold sheet in the long-term use process of the interventional instrument implanted in the body is avoided.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an interventional instrument delivery system. Background technique [0002] With the rapid development of medical technology and modern digital medical imaging technology, various high-level imaging equipment helps doctors to accurately see the internal structure of the human body, the size of the lesion and its relationship with the surrounding tissue without opening the human body tissue through surgery. Interventional surgery is a treatment developed on the basis of the development of these modern technologies. The guidance of medical imaging equipment is the key to complete interventional surgery and plays an important role in interventional treatment, enabling interventional operations to be performed in real-time and three-dimensional under video guidance. Usually, under the guidance of modern digital medical X-ray imaging equipment, interventional devices are ...

Problems solved by technology

[0008] In order to determine the position of the interventional instrument, three development points can also be fixed on the outer wall of the interventional instrument along its circumference. The development point is to sew the gold sheet on the interventional instrument, because it is seen in the actual operation process. The two-dimensional imaging image is originally three-dimensionally arranged on the interventional device. After two-dimensional projection, there is no way to confirm whether the valve development point is actually in front of the interventional device or behind it, and there is no way to confirm whether the position of the valve is reasonable.

[0009] On the other hand, the three development points are all made of gold, and need to be set on each interventional device, which is very expensive

The production process is also relatively complicated, and it must be sewn on the valve frame of the interventional device very carefully. The development point is left in the human body together with the interventional device for a long time, and the risk of the development point falling is very high.
