Embodiment Construction

[0013] Magnetic screen (Magnetic Screen or Magnetic Shield) is to use high saturation ferromagnetic material to contain the magnetic field lines in a specific volume. It can not only prevent the influence of external ferromagnetic substances on the uniformity of the magnetic field inside the magnet, but also greatly reduce the distribution of stray magnetic fields outside the magnetic shield.

[0014] After installing the magnetic shield, the distance from the center of the magnet to the 5 Gauss line can be reduced from 9.2m to 4.2m on the X and Y axes, and from 11.6m to 5.8m on the Z axis. The retraction of 5 Gauss line is about 5m, so it is a very effective magnetic field isolation measure to set up magnetic shielding body in the operating room of magnetic navigation system.

[0015] The magnetic shielding body in the operating room of the magnetic navigation system can not only protect the magnetic field in the operating room from being disturbed by other external factors, ...

Abstract

The invention discloses a magnetic shielding protection body construction method for a magnetic navigation system operating room, which comprises the following steps of: site planning and examination; carrying out alignment to an operating room building, performing building positioning and setting and alignment on a magnetic shielding operating room according to a plane figure, a floor, a top surface, a wall magnetic shielding arrangement diagram and a detailed structure map in the magnetic navigation system operating room; and arranging inner and outer position lines of building retaining walls, X and Y centering axes, a control room, an operating room, equipment room wall position lines, regional axes, induction doors, a hand push door position line, electric slots and pipe laying channel lines of the magnetic navigation system operating room on the floor, wherein the requirements of the precision control are that the length-width error is controlled within 2mm, and the diagonal error is controlled within 4mm; mounting a ground component; mounting the magnetic navigation system; carrying out inspection and acceptance of the magnetic shielding; and the like. According to the operating room magnetic shielding protection body construction method, the health risk generated in the process of working around a magnet is reduced to the greatest degree, accidents are avoided, magnetic leakage is completely eliminated, and preventative measures are taken before the accidents occur.

Description

technical field [0001] The invention relates to a magnetic shielding protection project suitable for a magnetic navigation system operating room. Background technique [0002] The application of magnetic navigation system technology in the clean operating room of the hospital has solved the problem of precise positioning and treatment of high-end complex and fine interventional operations such as coronary heart disease interventional therapy, electrophysiological mapping, radiofrequency ablation, biventricular pacemaker implantation, neurological intervention, and radiological intervention. It also brings the benefits of simplifying and optimizing the surgical operation process, lowering the threshold of clinicians' surgical skills, greatly shortening the operating time, zero radiation radiation for medical staff, making patients more relaxed, and improving the turnover rate of surgery. Therefore, the magnetic navigation system The construction of clean operating rooms has i...
