Technical Field

The invention belongs to the field of medical instruments, relates to an internal telescopic floor of a rotating rack, and particularly relates to a matching structure of the rotating rack and the internal telescopic floor.

Background

The traditional cancer treatment uses high-energy photons such as X-rays or gamma rays to destroy cancer cells, and the greatest disadvantage of the treatment method is that healthy cells surrounding the cancer cells are also irradiated by the radiation, so that the cancer cells are killed and secondary damage is caused to human bodies. Meanwhile, the conventional treatment method requires a very large dose to kill cancer cells at a deep portion because photon energy is rapidly decreased in the human body.

Proton therapy is a technology that has been rapidly developed in the field of cancer treatment in recent years, and its advantages are more apparent especially in the course of cancer treatment where there is a high risk of using conventional therapeutic methods. Protons, neutrons and electrons are the main elements of atomic composition, a proton has a unit mass and a unit positive charge, a proton has a half-life greater than 1032, and a proton will decay into a neutron, a positron and a neutrino.

When proton is used for treatment, the proton curve shows that the curve is increased slowly and then becomes fast, and the curve goes to zero after the peak value is increased to the Bragg peak value, and the inherent characteristic of the proton provides ideal treatment performance for treating tumors, and has the following advantages: as long as the peak part is aligned to the tumor focus, the tumor part receives the maximum dosage value, the dosage utilization rate is greatly improved, and the curative effect is best; normal cells, including skin, before a tumor are usually exposed to the maximum dose of 1/3-1/2, i.e., less damage than in the case of X-rays or electrons; normal cells or the nameplate organs behind the tumor are essentially not irradiated and not damaged. The visible proton therapy can overcome the defects of X-ray and electron therapy and become an ideal means for treating tumors, and the root of the visible proton therapy is the Bragg peak characteristic derived from protons.

Therefore, the proton treatment center is provided with a rotatable rotary treatment room, the rotary treatment room is the tail end of the whole proton treatment and is directly contacted with a patient, the design of the rotary treatment room is very important for the feeling of the patient treatment, the design of the telescopic floor of the rotary treatment room is complete for the ground of the rotary treatment room, the condition that the patient looks at the rib plate inside the rotary rack directly when receiving the treatment in the rotary treatment room is avoided, psychological pressure is brought to the patient during the treatment, and the structural design of the telescopic floor plays a good role in improving the treatment experience of the patient.

In order to realize the concept, a technical scheme is provided.
