Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a pressing device for accelerator simulation positioning phantom. Background Art

[0002] Medical accelerators are a type of particle accelerator used in biomedicine to perform radiotherapy on tumors. Charged particle accelerators are electromagnetic devices that use artificial methods to accelerate various types of charged particles to higher energy with the help of different forms of electric fields. They are often called "particle accelerators" or "accelerators" for short. In order for charged particles to gain energy, there must be an accelerating electric field. Accelerators are divided into various types based on the different types of accelerated particles, the different forms of accelerating electric fields, and the different trajectories followed by the particle acceleration process.

[0003] When using an accelerator to treat cancer patients, the patient needs to be fixed in a certain treatment position for a long time in order to accurately irradiate the patient's lesions. The existing fixation operation is to position the patient by pressing down a shaped mesh mold to shape the mesh mold to be consistent with the patient's supine position. However, the existing mesh mold usually requires two or even three people to cooperate in the pressing process, but there are still certain errors and difficulties in completing this process manually, and it is easy to have unstable fixation, or the mesh mold is unevenly stressed during the pressing process, resulting in the mesh mold failing to play a fixing role. Multiple people are required to operate, wasting doctor resources, and the fixation method is time-consuming and labor-intensive. Utility Model Content

[0004] The purpose of the utility model is to provide a pressing device for accelerator simulation positioning phantom, which is convenient for a single person to perform the operation of fixing the patient's body position when using an accelerator for treatment, effectively reducing the manpower invested in the shaping process, and at the same time, the pressing force is uniform, convenient and quick to position, and easy to operate, so as to solve the technical problems of requiring multiple people to operate, wasting doctor resources, and time-consuming and labor-intensive fixing methods.

[0010] Furthermore, the pressing device includes a connecting rod telescopic mechanism A and a cross bar; the connecting rod telescopic mechanism A is provided with four, installed in pairs, and connected with the cross bar to form an "I" shape, and the connection is rotatable. The connecting rod telescopic mechanism A and the cross bar are straightened to form an "I" shape, and when the cylinder transverse connecting rod B moves toward the cylinder transverse connecting rod A, the connecting rod telescopic mechanism A and the cross bar can ensure that the cylinder transmission stroke is consistent from left to right, and play the role of stroke limit.

[0011] Furthermore, the lower connecting rod of the main body support is provided with a quick clamp; there are four quick clamps, which are evenly installed on the two lower connecting rods of the main body support.
