Description

Technical Field

[0001] This utility model relates to the technical field of connection structure between treatment head and rotating frame, and more specifically, this utility model relates to a connection structure between a non-fixed treatment head and a rotating frame. Background Technology

[0002] In the field of modern medicine, many treatment methods rely on medical equipment equipped with specific treatment heads. The treatment head needs to be fixed on a rotating gantry through a connecting structure. For example, in radiotherapy, the treatment head of a linear accelerator needs to be precisely aimed at the patient's lesion site. In laser therapy, the laser treatment head needs to be flexibly adjusted according to the condition of the patient's skin or internal tissues.

[0003] In traditional medical equipment, the treatment head and rotating gantry are mostly connected in a fixed manner. This connection method has many limitations. First, because the position of the treatment head is relatively fixed, it is difficult to achieve precise positioning and adjustment from all angles when facing patients of different body types and with different lesion locations, resulting in poor treatment effects. Furthermore, when patients need to make slight adjustments to their position during treatment due to discomfort or treatment requirements, the fixed treatment head cannot make corresponding changes, affecting the continuity and accuracy of treatment. Therefore, a non-fixed connection structure between the treatment head and the rotating gantry is proposed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a connection structure between a non-fixed treatment head and a rotating frame to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connection structure between a non-fixed treatment head and a rotating gantry, comprising a gantry mounting plate and a treatment head, and a connection mechanism located between the gantry mounting plate and the treatment head. The gantry mounting plate has a mounting groove on the side near the treatment head, and positioning grooves are symmetrically formed on both sides of the inner cavity of the mounting groove. The treatment head has a locking groove on the side near the gantry mounting plate. The mounting groove and positioning groove facilitate the installation of the connection mechanism on one side of the gantry mounting plate, and the locking groove facilitates the connection of one end of the connection mechanism to the treatment head.

Through the cooperation of the positioning mechanism and the positioning groove, the base plate of the connecting mechanism can be installed and fixed on the frame mounting plate. Through the cooperation of the plug rod and the first turntable, the connecting plate can be rotated on the top of the fixing column, and the rotation angle of the plug rod can be fixed by rotating the fastening bolt, which is convenient for adjustment and use.

[0007] A connecting ear plate is fixedly connected to the top of the connecting plate, and a top plate is provided on the top of the connecting plate. A retaining strip is fixedly connected to the top of the top plate. A compression screw is symmetrically inserted at both ends of the top plate. An anti-slip plate is rotatably connected to the top of the compression screw. A first screw is inserted in the middle of the connecting ear plate. Through the cooperation of the retaining strip and the retaining groove, the treatment head is easily positioned and connected to the top plate, facilitating sliding installation and disassembly. By rotating the compression screw, the anti-slip plate is controlled to compress the positioning block, thus fixing the position of the top plate. By rotating the first screw, the top plate can be rotated on the top of the connecting plate through the cooperation of the connecting block and the connecting ear plate. The rotation angle is easily fixed through the cooperation of the nut and the first screw, improving the usability.

[0009] Preferably, the extrusion screw is threadedly connected to the top plate, one side wall of the anti-slip plate is in contact with the wall of the treatment head, and the extrusion screw is located on both sides of the connecting plate. By rotating the anti-slip plate, the extrusion screw can be controlled to extrude the treatment head, thereby fixing the installation position of the treatment head.

Through the cooperation of the connecting block and the connecting ear plate, the top plate and the connecting plate can be connected, and the nut is limited by the fixing groove. The extrusion strength can be adjusted by rotating the first screw, thereby adjusting the rotation angle and fixing it, improving the use effect.

[0011] Preferably, the first turntable is located in the middle of the fixed column, and one end of the fastening bolt is in contact with the wall of the insertion rod. The insertion rod can be rotated at the top of the fixed column by the first turntable, and the rotation position can be fixed by the fastening bolt.

One end of the second screw corresponds to one inclined surface of the positioning block, and multiple stabilizing rods are inserted in the middle of the second screw. A spring is sleeved on one end of the positioning block in the space of the stabilizing rod. The spring pushes the limiting plate, causing the positioning block to retract into the mounting block. By rotating the second turntable to control the second screw to squeeze the positioning block, the positioning block can be moved horizontally until one end of the positioning block is inserted into the positioning groove, which is convenient for fixing and use. The stabilizing rods also improve the stability of the movement of the limiting plate.
