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 a tumor radiotherapy device capable of realizing accurate positioning. The tumor radiotherapy device capable of realizing the accurate positioning comprises a base, a rotary barrel, a second driving mechanism and a reset mechanism, wherein two connecting elements are hinged to the side wall of the rotary barrel andare independently provided with a radiation light source and a positioning light source; the radiation light source and the positioning light source are distributed at an interval on one circle around the axial line of the rotary barrel; a minimum radius angle of the centers of the positioning light source and the radiation light source on the circle is a; the second driving mechanism is used fordriving the two connecting elements to move to enable the positioning light source and the radiation light source to synchronously swing at equal amplitude; and the reset mechanism is used for controlling the first driving mechanism to enable the rotary barrel to rotate along a first direction at a set angle a so as to move the radiation light source to the position of the positioning light source before resetting. The tumor radiotherapy device capable of realizing the accurate positioning can be used for reducing a deviation between a practical radiation area of the radiation light source and a simulated positioning area of the positioning light source

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a precisely positioned tumor radiotherapy device. 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 The process generally requires the use of precisely positioned tumor radiation therapy devices. [0003] Patent No. CN104548370B discloses a precisely positioned tumor radiotherapy device, such as figure 1 As shown, the precisely positioned tumor radiotherapy device 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 positi...
