Description

Technical Field

[0001] This utility model relates to the field of radiotherapy protection, specifically a radiotherapy patient protection device. Background Technology

[0002] Some cancer patients require radiotherapy, also known as chemotherapy. The goal of radiotherapy is to control and kill tumors through local treatment, aiming to eliminate tumors to the greatest extent possible while protecting the function of normal tissues and organs. In radiotherapy for neck skin tumors, the lesion site needs to be exposed while other areas are shielded. For example, Chinese utility model patent application number 202420265825.5 discloses a radiotherapy protection device, including a protective mechanism and an adjustment mechanism. The protective mechanism includes a fixed plate and a movable plate. A radiotherapy port is formed on the inner wall of one side of the fixed plate. Traction plates are installed at both ends of one side of the movable plate. A fixing pin is provided between the traction plate and the fixed plate. The adjustment mechanism includes a fixed frame, with an adjusting screw installed on the inner wall of the top of the fixed frame. Movable baffles are sleeved on the outer walls of both ends of the adjusting screw.

[0003] The aforementioned radiotherapy protection device, through the outward extension of the traction plate, allows adjustment of the distance between the fixed plate and the movable plate. A fixing pin passes through the fixing hole and connects to the adjacent connecting hole, enabling the protection mechanism to protect the normal skin of the patient's neck. The rotation of the adjusting screw causes the two movable baffles to move in opposite directions, allowing adjustment of the radiotherapy port and facilitating radiotherapy procedures on the patient's neck. However, a limitation was discovered during use: while the radiotherapy port is adjusted by moving the two movable baffles, it only allows for left-right adjustment, not up-down adjustment. This means it cannot adjust the overall size of the radiotherapy port according to the size of the lesion, thus presenting a limitation. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a radiotherapy patient protection device that allows for the replacement of appropriate radiotherapy ports according to the size of the lesion, effectively solving the problems mentioned in the background art.
