Description

Technical Field

[0001] This utility model relates to the field of nuclear magnetic resonance medical bed technology, specifically a tool for replacing the body coil. Background Technology

[0002] The Siemens superconducting magnetic resonance imaging (MRI) radio frequency system includes a main coil, an RF amplifier, and a receiving channel board. The main coil, weighing approximately 130 kg, is located inside the magnet cavity, on the inner wall of the gradient coil. When the main coil malfunctions, it needs to be replaced entirely. This requires four people to lift the main coil out of the magnet cavity. The distance between the main coil and the inner wall of the gradient coil is narrow, and there are circuits present. Because the main coil lacks a good leverage point, there is a frequent risk of injury to hands and damage to the gradient coil circuitry during manual lifting. Therefore, this invention proposes a tool for replacing the main coil. Utility Model Content

[0003] The purpose of this invention is to provide a general coil replacement tool to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a general coil replacement tool, including a wooden slide rail and two sets of replacement handles. The wooden slide rail includes a first side plate, and a second side plate symmetrically arranged on one side of the first side plate. The first side plate and the second side plate are fixedly connected by several side plate connecting beams. The first side plate and the second side plate are provided with inclined surfaces at 2°. The replacement handles include two sets of side connectors. The two sets of side connectors have a square structure design and are symmetrically arranged between each other.

[0005] Preferably, both sets of side connectors are provided with rod grooves on their outer sides, and a handle rod is fixedly connected between the rod grooves of the two side connectors by bolts.

[0006] Preferably, the outer wall of the side connector is provided with a coil connection hole located on the side of the rod groove, and the coil connection hole is a threaded hole.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] This utility model's main coil replacement tool features a detachable replacement handle mounted on the main coil. This handle serves as a force point for the main coil during replacement, allowing workers to better handle it and apply force, avoiding hand pressure and reducing safety hazards. Replacement is simple: just pull the main coil manually via the handle, guiding it through a wooden slide rail. This reduces the need for four people to lift the coil, effectively decreasing manpower. In practice, only two people are required to complete the replacement. The sliding pull method also reduces fluctuations during lifting, preventing damage to the main coil or gradient coil caused by human error, avoiding circuit risks, improving safety and replacement quality. It is easy to use, simple in structure, and suitable for widespread application. Attached Figure Description

[0016] Please see Figure 1-3 The present invention provides an embodiment of a main coil replacement tool, comprising a wooden slide rail 1 and two sets of replacement handles 2. The wooden slide rail 1 includes a first side plate 101, and a second side plate 102 symmetrically arranged on one side of the first side plate 101. The first side plate 101 and the second side plate 102 are fixedly connected by several side plate connecting beams 103 to form a wooden replacement slide rail. The first side plate 101 and the second side plate 102 are provided with inclined surfaces at 2°, which facilitates the guiding and pulling out of the main coil. The replacement handles 2 include two sets of side connecting parts 201. The two sets of side connecting parts 201 are square in design and are symmetrically arranged between each other.

[0017] In this embodiment, both sets of side connectors 201 are provided with rod grooves 203 on their outer sides. The rod grooves 203 of the two side connectors 201 are fixedly connected to the handle rod 202 by bolts. This structural design makes it easy to disassemble the handle rod 202 and the rod groove 203, and it is convenient to disassemble and store them when not in use.

[0018] Furthermore, a coil connection hole 204 is provided on the outer wall of the side connector 201 and on the side of the rod groove 203. The coil connection hole 204 is a threaded hole. In actual use, the replacement handle of this utility model can be installed on the main coil through the coil connection hole 204. In this way, the replacement handle 2 can be used as a whole for hand-held force release, making it convenient to lift the main coil and replace it.

[0019] Working principle: When it is necessary to replace the main coil, the MRI bed can be disassembled to expose the main coil. This utility model is equipped with two sets of replacement handles 2. At this time, the two sets of replacement handles 2 are installed at the bottom positions on both sides of the main coil through the coil thread holes 203 of the side connector 201. In this way, the replacement handles 2 can be used as a force-bearing structure to lift the main coil.

[0020] After the two sets of replacement handles 2 are installed, fix the wooden slide rail 1 on the bed of the scanning bed. At this time, the wooden slide rail 1 is placed in front of the main coil (that is, the bottom of the inclined surface of the wooden slide rail 1 is placed in front of the main coil).

[0021] Then, by manually holding the front end and replacing the handle 2, the main coil can be lifted upwards and dropped onto the wooden slide rail 1. At the same time, the main coil is pulled outwards to move it to one side of the wooden slide rail 1. When it is fully pulled out, the main coil is placed on the wooden slide rail 1, thus completing the removal of the main coil.

[0022] During installation, place the new main coil onto the wooden slide rail 1, and install the replacement handle 2 of this utility model at both the front and rear ends of the new main coil. Then rotate the wooden slide rail 1 180° so that its head faces the bed frame. Then pull the main coil into the bed frame through the replacement handle 2 at one end. It is convenient to use and quick to install. After the main coil is installed, remove the wooden slide rail 1 and the replacement handle 2.

[0023] This utility model's main coil replacement tool features a detachable replacement handle 2 mounted on the main coil. This handle serves as a force point for the main coil during replacement, allowing workers to better handle it and apply force, preventing hand injuries and reducing safety hazards. During replacement, the main coil is manually pulled along a wooden slide rail by the handle, reducing the need for four people to lift it. This significantly reduces manpower; in practice, only two people are required to complete the replacement. The sliding pull method also reduces fluctuations during lifting, effectively preventing damage to the main coil or the gradient coil caused by human error, avoiding circuit risks, improving safety and replacement quality. It is easy to use, has a simple structure, and is suitable for widespread application.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
