Description

Detachable jack U-shaped radiotherapy body position fixing plate

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a U-shaped radiotherapy body position fixing plate with detachable jacks.

Background

The radiotherapy generally needs to be divided into multiple times, in order to ensure the repeatability and the accuracy of the treatment, the patient needs to be fixed and positioned in a body position, the head and neck body position fixing mode is generally implemented by combining a U-shaped integrated body position fixing plate, a head and neck supporting pillow and a U-shaped thermoplastic surface mold, the patient lies on the body position fixing plate, the head and neck is supported by the head and neck, and the U-shaped thermoplastic surface mold is fixed on the body position fixing plate through a bolt. In order to ensure the repeatability and the accuracy of the body position of a patient, the key point of the fixing mode is that the U-shaped thermoplastic surface die can be stably fixed on the body position fixing plate in repeated treatment.

At present, the connection of the U-shaped thermoplastic surface mold and the body position fixing plate is realized through a plurality of fixing bolts, the fixing bolts are arranged at the edges of the U-shaped thermoplastic surface mold, a plurality of jacks are arranged on the body position fixing plate, and when a plug of the bolts is pressed down to enter the jacks on the body position fixing plate, the bolts are locked, so that the fixing of the U-shaped surface mold is realized, and the U-shaped surface mold can be taken down when the plug is lifted. In clinic, the fact that the fixing bolt is severely worn on the jack of the body position fixing plate in the process of repeated use is found, and the stability of connection between the U-shaped thermoplastic surface die and the body position fixing plate is difficult to guarantee after the jack is worn, so that the accuracy and precision of radiotherapy are reduced. In order to ensure the quality of radiotherapy, the use is stopped when the jack of the body position fixing plate is seriously worn. In order to reduce the blocking and attenuating effects of the body position fixing plate on radiotherapy rays, the body position fixing plate is usually processed by using carbon fiber materials, so that the cost is high, the body position fixing plate is excessively wasted due to the fact that the fixing insertion holes are damaged, the cost is increased, and resources are wasted.
