Description

Technical Field

[0001] The utility model relates to the technical field of mechanical arms, in particular to a mechanical arm of a particle beam treatment device. Background Art

[0002] Radiation particle therapy is a precise radiotherapy that uses radiation to act on tumor cells, causing tumor cell necrosis.

[0003] Radiation particle therapy mainly uses radiation to act on tumor cells, which can cause specific damage to the DNA in the nucleus of tumor cells, leading to the death of tumor cells, thereby achieving the effect of treating tumors. Radiation particle therapy can be used to treat various malignant tumors, such as brain tumors, lung tumors, esophageal tumors, breast tumors, etc., and can achieve good therapeutic effects.

[0004] At present, when performing radiation particle therapy, it is necessary to use a mechanical arm to fine-tune the patient's position and move the patient to the imaging position (within the CT aperture) or the treatment position (in front of the treatment head). After searching, the China Patent Network discloses a mechanical arm joint assembly with the publication number CN219426829U. Although the joint unit can be used to transmit the No. 1 mechanical arm and the No. 2 mechanical arm to achieve dynamic adjustment, the rotating component can be used to drive the No. 1 mechanical arm and the No. 2 mechanical arm to perform circular rotation adjustment, which expands the adjustment range of the No. 1 mechanical arm and the No. 2 mechanical arm, and has strong flexibility. At the same time, the No. 2 mechanical arm can be correspondingly transmitted with the help of the transmission component, so that the angle between the No. 1 mechanical arm and the No. 2 mechanical arm is changed to achieve adjustment, which is easy to use. With the assistance of the fine-tuning unit, the tension of the transmission belt can be adjusted to ensure the accuracy of power transmission. However, the mechanical arm lacks the corresponding warning function. When the mechanical arm is moving, it is very easy to hit the surrounding medical staff and medical equipment. The overall safety and practicality are not high.

[0005] To this end, a robot arm of a particle beam therapy device is proposed. Utility Model Content

[0021] A compression spring is provided on the outer wall of the bayonet;

[0022] One end of the compression spring is fixed to the auxiliary plate, and the other end of the compression spring is fixed to the connecting strip.

[0023] Compared with the prior art, the beneficial effects of the utility model are:

[0024] The utility model connects the first half connecting ring and the second half connecting ring to the outer wall of the annular seat by fixing bolts, and then the connecting strip, the adjustment strip and the warning plate can be connected to the outer wall of the mounting seat, and then the warning light bar is started, and the warning plate and the warning light bar cooperate to warn the medical staff, which can effectively prevent the medical staff from standing within the activity radius of the robot arm body and the medical equipment from being placed within the activity radius of the robot arm body. Compared with the existing ones, the utility model has a warning function, which can effectively prevent the robot arm body from hitting the surrounding medical staff and medical equipment when working, thereby improving the overall safety and practicality.

[0025] The utility model pulls the pull rod, which drives the pin to move in the first clamping hole and the second clamping hole. At this time, the compression spring will perform a corresponding stretching movement. After one end of the pin is disengaged from the second clamping hole, the position of the movable adjustment bar in the movable cavity of the connecting bar can be adjusted, thereby achieving the adjustment of the position of the warning sign. After the position of the warning sign is adjusted, the pull rod is released. At this time, the compression spring will perform a corresponding contraction movement and drive one end of the pin to clamp into the second clamping hole to complete the fixation of the warning sign. Compared with the existing ones, the utility model can adjust the position of the warning sign so that the warning sign can meet the different working radii of the robot arm body, and is more practical.
