[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a bracket for assisting the installation of a gamma knife head frame. Background Art

[0002] The gamma knife head frame is a fixing device used in gamma knife surgery, which can be safely and accurately fixed on the patient's head. It consists of multiple support points and adjustable clamping devices, which can keep the patient's head in a stable position during surgery. By fixing reference points on the head frame, the doctor can accurately align the area to be treated according to the predetermined plan, ensuring that the gamma knife beam accurately irradiates the target area, achieving precise treatment while minimizing damage to surrounding normal tissues, and providing a safer and more effective treatment plan. However, when installing the gamma knife head frame, at least two doctors need to cooperate with each other, one to assist in the installation of the head frame, and the other to install it. During the installation, one doctor needs to support and adjust the position to ensure the accuracy of the installation, and the other to fix the installation. The installation process is cumbersome and requires more labor, which is very inconvenient, so an auxiliary device is needed to assist in the fixation of the head frame.

[0003] At present, there are also related brackets for auxiliary gamma head frames, such as patent No. CN215136099U which discloses a bracket for auxiliary installation of a gamma knife head frame. The device is respectively mounted on the shoulders on both sides of the patient through shoulder supports and can be adjusted in many aspects such as height, which facilitates the doctor's operation to a certain extent; however, the device is directly placed on the patient's shoulders for use. Since the gamma knife head frame is made of metal and is completely placed on the patient's shoulders, it will cause pressure on the patient's shoulders and cause discomfort to the patient; at the same time, the device cannot adjust the angle of the head frame when it is fixed, which is not convenient for the doctor to make adjustments.

[0004] Therefore, there is a need for a bracket for assisting in mounting a gamma knife head frame, which can be adjusted according to the patient's sitting height and angle on the horizontal plane to find a suitable position; in addition, the bracket can clamp the auxiliary head frame, and while clamping, the height of the head frame can be fine-tuned through an adjustment mechanism, and the fixed adjustment inclination angle can be adjusted, and at the same time, one person can operate it, which can greatly save medical human resources.
