Description

Technical Field

[0001] The utility model relates to the technical field of radiotherapy, in particular to a radiotherapy auxiliary fixing device for head, neck and shoulder parts. Background Art

[0002] Radiotherapy is the treatment of malignant tumors and some benign diseases using one or more ionizing radiations. The means of radiotherapy is ionizing radiation. The most commonly used direct ionizing particles in radiotherapy are electrons, and the most commonly used indirect ionizing particles are photons. The energy range of X-rays used in radiotherapy is 1-25MV.

[0003] During radiotherapy, the patient's radiotherapy site needs to remain motionless. Therefore, when the patient is receiving radiotherapy, the patient's radiotherapy site will be fixed by a radiotherapy positioning film. The radiotherapy positioning film is mainly composed of a lying board mold, a frame mold and a positioning film. When in use, the positioning film fixedly connected to the frame mold is softened, and then the positioning film is covered on the patient's radiotherapy site, and the frame mold is fixed on the lying board mold. After the positioning film solidifies, a mold that fits the radiotherapy site is formed. Due to different physical signs of patients, each patient has a separately made mold, and after each patient uses it, the positioning film is basically scrapped. However, the existing frame mold and positioning film are fixedly connected together, which results in the frame mold being scrapped together when the positioning film is scrapped, causing waste.

[0004] The purpose of the utility model is to provide a head, neck and shoulder radiotherapy auxiliary fixation device to solve the problems mentioned in the above background technology. Utility Model Content

[0007] As a further improvement of the present invention, a slope is provided on the top of the lower clamping plate near one side edge of the L-shaped groove, and the bottom end of the slope is connected to the clamping groove.

[0008] As a further improvement of the utility model, a hollow column is fixedly installed on the transverse surface of the L-shaped groove of the lower clamping plate in the direction away from the clamping groove, a limiting ring is provided on the inner wall of the hollow column, a fixing column is provided at the bottom of the upper clamping plate, and an annular groove matching the limiting ring is provided on the outer wall of the fixing column.

[0009] As a further improvement of the utility model, grooves are provided at both side ends of the upper clamping plate, and the grooves can accommodate fingers extending into the inside.

[0010] As a further improvement of the utility model, the locking mechanism comprises a locking button, a fixing rod, a control spring, and a hollow sleeve, the hollow sleeve is fixedly mounted on the top of the fixing frame, the fixing rod is fixedly mounted on the bottom of the locking button, the outer sleeve of the fixing rod is provided with a sleeve, and the sleeve is movably mounted on the outer wall of the hollow sleeve, the upper clamping plate and the outer wall of the lower clamping plate are both connected to the fixing plate, and the fixing plates are in contact with each other. The inner side of the fixing frame is provided with a positioning groove that cooperates with the fixing plate, the fixing plate on the upper clamping plate is provided with a plurality of through holes, the fixing plate on the lower clamping plate is provided with limit holes that are aligned with the plurality of through holes up and down, the bottom of the fixing rod is symmetrically provided with limit blocks that are limit-fixed with the limit holes, the control spring is mounted on the outer wall of the fixing rod, and a limit groove is provided inside the hollow sleeve, the bottom of the control spring is fixedly connected to the limit groove, and the top of the control spring is movably connected to the bottom of the locking button.

[0011] As a further improvement of the utility model, the lock includes a fixed shaft and a rotating rod. The fixed shaft is fixedly mounted on the positioning plate, the rotating rod is rotatably mounted at the center of the fixed shaft, and a locking plate is fixedly connected to the top of the rotating rod, and the locking plate is used to lock the fixed frame.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a detachable frame, which is achieved by placing the edge of the positioning film in the L-shaped groove on the lower clamping plate, and then pushing the multiple buckles on the outer wall of the connecting block at the bottom of the upper clamping plate downward along the inclined surface of the edge of the lower clamping plate until the buckles slide into the clamping groove for clamping and fixing. Furthermore, when the upper clamping plate is pushed downward, the fixing column on the upper clamping plate enters the hollow column on the lower clamping plate, and when the buckles are clamped into the clamping groove, the annular groove on the outer wall of the fixing column and the limiting ring in the hollow column are limited and clamped for fixing, so that the frame fixes the positioning film more firmly. When the positioning film needs to be replaced, it is only necessary to insert a finger into the groove on the upper clamping plate and push toward one side of the positioning film so that the buckles are moved out of the clamping groove, and then push the upper clamping plate upward to achieve the initial positioning film removal.

[0014] 2. The utility model is provided with a detachable fixing frame. After the frame fixes the positioning film, the fixing plate on the outer wall of the frame is pushed into the positioning groove of the fixing frame, and then the locking button is grasped and pressed downward. At this time, the spring at the bottom of the locking button compresses the fixing rod through the through hole on the upper clamping plate fixing plate and extends to the limiting hole on the lower clamping plate fixing plate and contacts the bottom of the limiting hole. Then the locking button is rotated ninety degrees clockwise so that the limiting blocks on both sides of the bottom of the fixing rod enter the symmetrical arc grooves at the bottom of the limiting hole. At this time, the limiting blocks are tightly fixed to the top of the arc groove, thereby limiting the upward, downward and leftward movement of the fixing plate. When the positioning film needs to be removed, the buckle is moved out of the slot and the upper clamp is pushed upward. Due to the action of external force, the annular groove on the outer wall of the fixing column moves out of the hollow column along with the smooth edge of the limiting ring to achieve complete separation between the upper clamping plate and the lower clamping plate to take out the positioning film for replacement.

[0015] 3. The utility model is provided with a positioning plate, which is also provided with a plurality of locks. The fixing frame with the frame and the positioning film fixed is placed on the positioning plate, and then the locking plate on the fixing axis of the positioning plate is rotated so that the rotating rod fixedly connected to the locking plate is rotated at the center of the fixing axis until the bottom of the locking plate is driven to fit and restrict the top of the fixing frame to complete the rapid fixation between the fixing frame and the positioning plate. Before fixing the fixing frame, the positioning film is first heated and softened, and then tightly shaped with the patient's head, shoulders and neck, and then the fixing frame is fixed to facilitate the fixing and molding of the positioning film, thereby fixing the patient's head, shoulders and neck position.
