The multi-functional gamma knife treatment device for both head and body applications includes: a treatment head frame and a treatment head. The treatment head is pivotally connected to the treatment head frame. The multi-functional gamma knife treatment head for both head and body applications includes, from top to bottom, a shielding body 1, a radiation source body 2, a collimator body 3, and a shielding door 4. The shielding body 1, the radiation source body 2, and the collimator body 3 are all hemispherical covers. The radiation source body 2 is provided with a radiation source cavity 5. At least one radiation source 6 is arranged in the radiation source cavity 5. The radiation source body 2 is provided with a radiation switch mechanism 7. The radiation switch mechanism 7 controls the opening and closing of the radiation source cavity 5.

[0040] When the radiation switch mechanism 7 controls the opening of the radiation source cavity 5, the radiation source 6 corresponds to the collimation opening 8 of the collimator body 3. When the radiation switch mechanism 7 controls the closing of the radiation source cavity 5, the radiation source 6 is arranged out of alignment with the collimation opening 8 of the collimator body 3.

[0041] The treatment head can automatically achieve horizontal and vertical flipping. When horizontal, the treatment head is used for body radiotherapy. When the treatment head is in the vertical position, it is used for head radiotherapy. When body treatment is required, the flipping mechanism flips the treatment head to be parallel to the patient for treatment. When head treatment is required, the flipping mechanism flips the treatment head to be vertically arranged in front of the patient's head for treatment.

[0042] The treatment head is provided with a head-body treatment conversion shaft. The treatment head frame is provided with a rotating motor. Both ends of the head-body treatment conversion shaft are rotatably connected to the rotating motor. The treatment head frame can also be provided with a flipping support arm. When the treatment head flips, the flipping support arm supports the treatment head. The treatment head frame is provided with a lifting support column. The rotating motor is arranged at the top of the lifting support column.

[0043] The multi-functional gamma knife treatment device for both head and body applications according to the embodiment of the present invention can be used to treat the head and the body respectively by setting a treatment head frame and a treatment head. By setting a radiation switch mechanism on the radiation source body, when the radiation switch mechanism controls the opening of the radiation source cavity, the radiation source corresponds to the collimation opening of the collimator body. When the radiation switch mechanism controls the closing of the radiation source cavity, the radiation source is arranged out of alignment with the collimation opening of the collimator body, which can realize the rapid switching of the radiation source, improve the treatment effect, reduce treatment harm, and a source loading plug can be arranged at the position corresponding to the radiation source body of the shielding body, thus facilitating the loading, unloading, and replacement of the radiation source.

[0044] Preferably, the radiation switch mechanism 7 includes a drive motor 9, a drive link 10, and a rotary switch component 11.

The rotary switch component 11 is arranged in the radiation source chamber 5, and the radiation source 6 is arranged on the rotary switch component 11. The driver drives the rotary switch component to rotate through the drive link for switching.

[0045] In this embodiment, the driver drives the drive link to drive the rotary switch component to rotate for switching, which can quickly and accurately control the rapid opening and closing of multiple radiation sources, with accurate and timely response. Multiple sets of the driver, drive link, and driven rotary switch component can be set to adapt to different treatment requirements and achieve independent control of each set of rotary switch components, making the treatment more precise and effective.

[0046] Among them, the sliding switch component 11 includes a rotating gear 12 and a rotating shaft 13. The radiation source 6 is arranged on the rotating shaft 13. A radiation opening 14 is arranged at the position of the rotating shaft 13 corresponding to the radiation source 6. When the radiation switch mechanism 7 controls the opening of the radiation source chamber 5, the rotating shaft 13 rotates, and the radiation opening corresponds to the collimation opening position 8 of the collimator 3. When the radiation switch mechanism 7 controls the closing of the radiation source chamber 5, the rotating shaft 13 rotates, and the radiation opening 14 is arranged in a staggered manner with the collimation opening 8 of the collimator 3. One end of the rotating shaft 13 is connected to the drive link 10, and the other end of the rotating shaft 13 is rotatably connected to the radiation source chamber 2. A bevel gear 15 that cooperates with the rotating gear 12 is arranged at the end of the drive link 10 connected to the rotating shaft 13. The drive link 10 drives the rotating shaft 13 to rotate through the cooperation of the bevel gear 15 and the rotating gear 12, and the radiation source can be arranged along the length direction of the rotating shaft.

[0047] Specifically, when the radiation switch mechanism controls the opening of the radiation source chamber, the driver drives the drive link to rotate. The drive link drives the rotating shaft to rotate through the bevel gear and the rotating gear. The radiation opening corresponds to the collimation opening position of the collimator, and the radiation source emits rays through the radiation opening and the collimation opening. When the radiation switch mechanism controls the closing of the radiation source chamber, the driver drives the drive link to rotate. The drive link drives the rotating shaft to rotate through the bevel gear and the rotating gear, and the radiation opening is arranged in a staggered manner with the collimation opening of the collimator.

[0048] In this embodiment, through the mutual cooperation of the rotating gear, the rotating shaft, and the bevel gear, the rotation of the rotating shaft is realized, thereby opening and closing the radiation channel. The structure is simple, the failure rate is low, and the cooperation between the bevel gear and the rotating gear is close, with higher control precision. The rotation angle of the rotating shaft can be 90 degrees.

[0049] Preferably, the driving link 10 passes through the top of the shielding body 1, and the driving machine 9 is connected to one end of the driving link 10 extending out of the shielding body 1. A steering sensor is provided at the connection between the driving machine 9 and the driving link 10.

[0050] In this embodiment, by providing a steering sensor, the rotation angle can be accurately controlled, thereby improving the control accuracy and avoiding misoperation of the device.
