Description

Technical Field

[0001] The present invention belongs to the technical field of treatment heads for tumor treatment, and in particular relates to a non-rotational treatment head for tumor treatment. Background Art

[0002] Tumors are new organisms formed by the proliferation of local tissue cells. The acidity of tumors is slightly stronger than that of healthy body tissues. Tumors can form an "acid wall" to protect themselves from attacks by the immune system. The ion beam rotation therapy head (Gantry) is a cancer accelerator terminal delivery system that uses a pencil-shaped ion beam to treat tumors. It can rotate from 0°-180° or 0°-360° during the patient's treatment to effectively implement multi-directional treatment of tumors while reducing the radiation damage caused by ion beams to normal tissues and organs. Since RR Wilson proposed proton beam therapy for tumors in 1946, developed countries have successively built dedicated ion accelerator devices to provide variable energy and finely adjustable ion beams to achieve conformal treatment of lesions. The conformal treatment is the process of high-precision operation of ion beams to match the shape of the lesion by manipulating the lateral position and longitudinal energy distribution. In radiotherapy, the rotating treatment head (Gantry) that can supply beams at any angle is the most ideal ion beam therapy terminal delivery system for conformal treatment.

[0026] 2. The present invention installs the assembly module, and one end of the assembly column 1 passes through the bite tube and the coupling tube in sequence, and is embedded in the assembly column 2. During the period when the assembly column 1 is embedded in the assembly column 2, the assembly platform is directly opposite to the wedge-shaped groove. When the assembly platform passes through the coupling tube, the assembly column 1 is rotated to make the assembly platform and the wedge-shaped groove diverge from each other, and then the bite tube is rotated, the bite tube pulls the rotating tube to rotate, the rotating tube pulls the rotating sleeve to rotate, and the rotating sleeve pulls the coupling tube to move toward one side of the assembly column 2, and the coupling tube slowly presses the assembly platform, and the assembly column 1 is pressed in the assembly column 2, so as to achieve the purpose of firmly assembling the assembly column 2 and the assembly column 1. The assembly platform passes through the coupling cylinder, rotates the assembly column 1, and rotates the assembly platform to face the assembly groove, and then twists the rotating sleeve, the coupling cylinder presses the assembly platform, and the assembly platform is assembled in the assembly groove, and the protrusion is stuck in the stop hole; the reliability of the assembly between the assembly column 1 and the assembly column 2 can be enhanced, and the rotation between the assembly column 1 and the assembly column 2 can be restricted to prevent the assembly column 1 from rotating, pulling the assembly platform to rotate, and the compression rotation between the assembly platform and the coupling cylinder is damaged, resulting in a gap between the assembly platform and the coupling cylinder, thereby reducing the tightness of the assembly between the assembly column 1 and the assembly column 2; through the spiral beryllium copper wire 1 The installation of the coupling tube and the assembly sheet is separated, so that when the assembly column 1 passes through the coupling tube, there is no need to change the position of the coupling tube, and the coupling tube will press the bite tube toward one side of the rotating sleeve, so that the bite tube is always engaged with the rotating tube, ensuring the smoothness during the assembly of the assembly column 1 and the assembly column 2; the assembly column 1 is embedded in the assembly column 2, the coupling groove faces the movable groove, and the coupling pin passes through the movable groove and the coupling groove; the assembly column 1 is embedded in the assembly column 2, and the lower end of the coupling pin is stuck in the movable groove and the coupling groove. At this time, the secondary connection of the assembly column 1 and the assembly column 2 is achieved, and then the assembly column 1 and the assembly column 2 are assembled. The second column is double-connected. When the buckle part and the rotating connection part are loose or cannot be disassembled, the connection can be achieved through the connection pin, and the connection can be maintained for a certain period of time, so as to leave enough time for subsequent maintenance; through the installation of the connection groove and the connection pin, after the connection pin is embedded in the connection groove, the tapered end of the connection pin presses the inclined wall in the connection groove, so that the assembly column one has the momentum to move toward the assembly column two, and the reliability of the connection between the assembly column one and the assembly column two is further strengthened; through the installation of the handle, the bite cylinder is rotated, and the handle is held tightly to prevent the bite cylinder from being rotated for easy operation;The connecting pin can only achieve the purpose of temporary connection. The key is to connect the assembly column 1 and the assembly column 2 by the buckle part and the rotating connection part. Therefore, it is necessary to pay attention to the reliability of the rotating cylinder. Therefore, a movable bar is installed. When the bite cylinder is rotated, the movable bar is pressed into the groove, and the splicing piece moves to the bottom of the groove, and the splicing piece moves away from the teeth. At this time, the bite cylinder can be rotated arbitrarily. After the connection between the assembly column 1 and the assembly column 2 is completed, the movable bar is released. Under the deformation action of the spiral beryllium copper wire 2, the movable bar moves out of the groove, and the splicing piece is stuck between a pair of adjacent teeth, which restricts the handle, that is, restricts the bite cylinder, and then the rotating sleeve is The stop position ensures the reliability of the connection between the assembly column 1 and the assembly column 2; the connection tube moves toward the assembly column 2, the bracket pulls the embedded column to move toward the movable groove, and one end of the embedded column is inserted into the connection port. At this time, the embedded column assembles the connection pin in the movable groove, thereby achieving the purpose of double connection, making the connection between the assembly column 1 and the assembly column 2 more stable; the other end of the embedded column is embedded in the connection port. If the connection tube needs to continue to move toward the side of the assembly column 2, the reliable connection between the assembly column 1 and the assembly column 2 can be completed. At this time, the embedded column presses the spiral beryllium copper wire 3, and the embedded column moves toward the bottom of the hoop tube, so that the connection tube can continue to move;

[0027] With the help of the assembly module, the treatment head can be easily disassembled and assembled, so as to facilitate the repair and maintenance of the treatment head.
