Leg fixing bracket used for lithotomy position radiation treatment

Abstract

The invention discloses a leg fixing bracket used for lithotomy position radiation treatment. The leg fixing bracket comprises a bottom plate, two supports and one supporting rod, the bottom plate is arranged between the two supports in a mortised mode, and each support comprises a bottom post, a supporting plate A and a supporting plate B, wherein the lower end of the supporting plate A and the lower end of the supporting plate B are mortised into the bottom post through plates, and the upper end of the supporting plate A and the upper end of the supporting plate B are connected through the supporting rod to form a complete triangular structure. The leg fixing bracket is simple in structure, convenient to use, safe, comfortable, low in cost price and capable of achieving a very good fixing effect.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a leg fixing bracket for radiotherapy in lithotomy position. Background technique [0002] Vulvar cancer accounts for about 3% to 5% of primary malignant tumors of the female reproductive tract and 1% of female malignant tumors. Radiotherapy plays an important role in the treatment of vulvar cancer. Postoperative radiotherapy can improve the prognosis of vulvar cancer patients with advanced clinical stage or inguinal lymph node metastasis. For the radiotherapy of vulvar cancer, the traditional body position fixation method cannot well avoid the normal tissue so that the tumor part can be fully exposed, and the lithotomy position is a good method. However, the lithotomy position needs to raise the legs, and the fixation of the legs is a difficult problem. Domestic hospitals mostly use vacuum negative pressure bag heating plastic film fixation technology, but the legs are not easy ...

Problems solved by technology

For the radiotherapy of vulvar cancer, the traditional body position fixation method can not avoid the normal tissue well to fully expose the tumor part, and the lithotomy position is a good way

However, the lithotomy position needs to raise the legs, and the fixation of the legs is a difficult problem

Domestic hospitals mostly use vacuum negative pressure bag heating plastic film fixation technology, but the legs are not easy to fix, which affects the positioning accuracy and poor position repeatability
