Problems solved by technology

[0004] The above-mentioned technical solution has at least the following defects: since the positioning light source 4 is located below the radiation light source 2 when simulating the positioning of the lesion area of ​​the patient, the actual radiation area of ​​the radiation light source 2 is different from the simulated positioning area of ​​the positioning light source 4, Specifically, the actual radiation area of ​​the radiation source 2 is larger than the simulated positioning area of ​​the positioning light source 4, so that the radiation source 2 will irradiate more normal tissue cells, which will cause unnecessary radiation damage to the patient's body. Therefore, it is urgent to improve the

Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly. In addition, if there are descriptions involving "first", "second" and so on in the embodiments of the present invention, the descriptions of "first", "second" and so on are only for descriptive purposes, and should not be interpreted as indicating or implying Its relative importance or implicitly indicates the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly o...

Abstract

The invention relates to the technical field of medical equipment, in particular to medical equipment for radiation therapy. The medical equipment for radiation therapy comprises a base, a rotary drum, a second driving mechanism and a reset mechanism. Two connecting pieces are hinged to the side wall of the rotary drum, a radioactive light source and a positioning light source are mounted on the two connecting pieces respectively and distributed on a circle around the axis of the rotary drum at intervals, and the minimum central angle of the center of the positioning light source and the center of the radioactive light source on the circle is a; the second driving mechanism is used for driving the two connecting pieces to move, so that the radioactive light source and the positioning lightsource synchronously swing at equal amplitude; the reset mechanism is used for controlling the first driving mechanism to enable the rotary drum to rotate by a set angle a in the first direction so as to move the radioactive light source to the position of the positioning light source before resetting. According to the medical equipment for radiation therapy, the deviation between the actual radiation area of the radioactive light source and the simulated positioning area of the positioning light source can be reduced.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical equipment for radiotherapy. Background technique [0002] Malignant tumors are one of the main causes of death in our country. At present, there is no specific treatment for malignant tumors. Radiation is generally used for treatment, that is, high-energy radiation is used to irradiate the tumor lesion area to achieve the purpose of treatment. In radiotherapy Medical equipment used in radiation therapy is generally used during the procedure. [0003] In the patent No. CN104548370B, a medical device for radiotherapy is disclosed, such as figure 1 As shown, the medical equipment for radiotherapy includes a base 1, a radiation source 2 and a positioning light source 4. The base 1 is provided with a radiation hole 5 and a radiation hole switch door 3 that can be opened and closed relative to the radiation hole 5. The positioning light source 4 is arranged on On ...
