Description

Body frame for hip bone radiotherapy

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a body frame for hipbone radiotherapy.

Background

Tumors are new organisms formed by local tissue cell proliferation under the action of various tumorigenic factors, and are classified into two categories, namely favorable tumors and malignant tumors according to the cellular characteristics of the new organisms and the degree of harm to the organisms, and cancers are the general term of the malignant tumors. Radiotherapy is one of the main treatment methods of tumors, and during radiotherapy, rays must be accurately irradiated to tumor tissues, and meanwhile, irradiation to normal tissues around the tumor should be avoided as much as possible, so whether the radiotherapy process can be accurately positioned is a very critical problem. In the existing radiotherapy, a patient needs to lie on a body frame of a radiotherapy equipment bed, and the positions of radiotherapy positions commonly used at present mainly comprise a prone position and a supine position. The prone position or the supine position is adopted, although the repeatability of the body position during radiotherapy can be better, and the quality of the radiotherapy can be well ensured, because a part of the positioning mark is positioned on the other side of the body of the target area, the positioning mark is far away from the target area, the accuracy is poor, and the positioning precision of the radiotherapy is influenced; in addition, a portion of the treatment radiation needs to pass from the bottom of the treatment couch and then enter the patient, which may affect the accuracy of the radiotherapy treatment dose.

Although the chinese patent with the publication number CN 104721962B discloses a breast radiotherapy body frame capable of being used in lateral position, the breast and the upper limbs of the human body are located near the same horizontal line, and the upper limbs of the patient can be lifted by the arm support and the handle bar, so that the lateral position of the patient can be easily fixed by only backing a lateral support plate. However, this structure is only suitable for radiotherapy of the upper half of the human body, and is not suitable for radiotherapy of the hip bone because: firstly, the side supporting plate only adjusts the left position and the right position through the inserting plate holes, the position adjusting precision is low, and the waist fixing device cannot be accurately suitable for fixing the waist of most patients; secondly, the hip bone is the bone of the waist of the human body and is positioned on a rotating point, and even if the upper body is supported by the upper limbs, the waist can not be ensured to be positioned on the lateral clinostatism; thirdly, the hip bone is adjacent to the hip of the human body, whether the hip is righted or not directly influences the accuracy of the hip bone lateral position, the lateral support plate connected only through the jack is difficult to implement large supporting force on the hip, and after long-term use, the top of the lateral support plate can be warped outwards, so that the positioning performance of the hip bone lateral position is influenced.
