[0002] When radiologists perform radiotherapy on patients with colorectal cancer, they usually require patients whose colorectal tumors are close to the perianal area to open their legs at a certain angle to facilitate the implementation of precise radiotherapy. At the same time, the thigh muscles and skin are kept outside the radiotherapy field as much as possible to avoid serious radiotherapy side effects. However, it is difficult to maintain a stable angle of the thighs for a long time during radiotherapy, and it may cause soreness or cramps in the thighs, affecting the progress of radiotherapy. Therefore, it is very important to design a colorectal cancer radiotherapy stent with an adjustable function, such as:

The position of the second fixing member is adjusted by sliding cooperation between the first rod and the first connecting member, rotating cooperation between the first rod and the fourth connecting member, sliding cooperation between the second rod and the fourth connecting member, and rotating cooperation between the second connecting member and the third connecting member. During the entire position adjustment process, the first fixing member remains connected to the operating bed, and only the various components of the bracket need to be adjusted to achieve flexible adjustment in multiple dimensions, so there is no need to adjust the position of the applicator by moving the entire bracket, thereby simplifying the position adjustment operation steps.

[0004] However, the above-mentioned existing technical solutions have the following defects: it is not convenient to realize the adjustment function of the spacing between the stents for colorectal cancer radiotherapy, and it is not convenient to realize the rapid assembly of the stents for colorectal cancer radiotherapy.
