Problems solved by technology

[0012] a. Set up a suspended rack on the ceiling. Due to the high position of the suspended rack, it brings a lot of difficulties in installation and maintenance
[0013] b. There are repetitions in the design of the degree of freedom, that is: the radiation head has translation along the X, Y, and Z directions and rotation around the Z axis, and the treatment bed has the freedom to move up and down along the Z axis and rotate around the Z axis. The degree is: move up and down along the Z axis and rotate around the Z axis, so that the treatment bed cannot get any desired position and angle during posture adjustment;
[0014] c. The suspended rack is set on the ceiling. Due to the weight of the radiation head and the self-weight of the suspended rack itself, there is a risk of the radiation head and the suspended rack falling. The consequences for the patients directly below will be disastrous

Abstract

The invention belongs to the field of medical equipment, relates to a radiotherapy device, and particularly relates to a device used for adjusting the posture of a human body in radiotherapy. The invention provides a radiotherapy device performing tracking and positioning by means of a Stewart robot platform. The radiotherapy device comprises the Stewart robot platform, a movement bed board and the human body. The static platform of the Stewart robot platform is fixed on the ground. The movement bed board is fixedly connected with the moving platform of the Stewart robot platform. The movement bed board comprises a bottom board and a cross slide table. The bottom board and the moving platform are fixedly connected. The cross slide table is flexibly connected on the bottom board. The human body is fixedly connected on the cross slide table. The cross slide table is arranged on the upper part of the Stewart robot platform so that precise adjustment capacity of the Stewart robot platform can be exerted and precise positioning and angle adjustment can be performed along with lesion parts. Therefore, complementary combination of coarse adjustment and fine adjustment can be realized, and precise positioning of the lesions can be rapidly realized in a wide range.

Description

technical field [0001] The invention belongs to the field of medical equipment, and relates to a radiotherapy device, in particular to a device for adjusting the posture of a human body during radiotherapy. Background technique [0002] Intraoperative radiotherapy is a new technology of tumor radiotherapy. It is during the operation. After the surgeon has removed the local tumor, he uses radiation to irradiate the tumor bed or residual tumor tissue that has been removed through the surgical field of view. It is widely used. It is used in the combined treatment of head and neck tumors, chest, abdomen, and pelvic tumors. [0003] Intraoperative radiotherapy began in the 1980s. Medical linear accelerators were used during surgery to directly irradiate the tissue surface with an open surgical field to kill local residual tumor cells. Since there was no dedicated intraoperative radiotherapy equipment at that time, the large-scale medical linear accelerator in the radiotherapy de...
