Problems solved by technology

However, the sleeve can only realize the connection of the conductive shielding layer, and cannot seal the connection joint between the extension lead and the electrode lead
Generally, it is necessary to add a silicone rubber sleeve to seal the connection joint, and then add the conductive shielding layer sleeve, so the structure is complicated and the difficulty of use in the clinical operation process is increased

Abstract

The invention provides a connecting mechanism of an implanted medical apparatus, the implanted medical apparatus and a connecting method of the implanted medical apparatus. The connecting mechanism ofthe implanted medical apparatus comprises a shielding sleeve and a sealing sleeve, wherein the shielding sleeve covers the periphery of the sealing sleeve, the sealing sleeve comprises a connecting cavity, the connecting cavity is used for installing a first connecting member inserted from one end of the connecting mechanism and a second connecting member inserted from the other end of the connecting mechanism, at the state that the first connecting member and the second connecting member are installed on the connecting mechanism, one end of the sealing sleeve is used for being connected to the outer circumferential surface of the first connecting member in a sealing manner, and the other end of the sealing sleeve is used for being connected to the outer circumferential surface of the second connecting member in a sealing manner. According to the connecting mechanism, while the shielding layers of the first connecting member and the second connecting member of the medical apparatus isconnected to prevent the RF-causing heating, the sealing of an electric connector of the first connecting member and the second connecting member is realized, and the connecting mechanism is simple and rapid in installation operation and reliable in connection.

Description

technical field [0001] The invention relates to the field of implantable medical devices, in particular to an MRI compatible implantable medical device connection mechanism, an MRI compatible implantable medical device using the connection mechanism and a connection method thereof. Background technique [0002] Compared with other imaging techniques (such as X-ray, CT, etc.), Magnetic Resonance Imaging (MRI) has significant advantages: MRI is clearer, has a high resolution for soft tissues, and There is no ionizing radiation damage to the human body. Therefore, magnetic resonance imaging technology is widely used in the clinical diagnosis of modern medicine. Today, it is estimated that at least 60 million cases worldwide are examined using MRI technology every year. [0003] When MRI works, three magnetic fields come into play. A high-intensity uniform static magnetic field B0, a gradient magnetic field that can be adjusted to any direction, and a radio frequency (RF) mag...
