Multifunctional radiotherapy body position fixing frame

Abstract

The invention discloses a multifunctional radiotherapy body position fixing frame, which is characterized in that it includes a main board one and a main board two, and a folding hinge switch is arranged between the main board one and the main board two; a scale scale is fixed on the edge of the main board one; The surface of the main board is provided with a number of small circular holes; the upper part of the main board one is provided with a head hole, and the head hole is provided with a head hole plug; the upper part of the front of the main board one is also provided with a headrest; Mammary gland hole, there is a breast hole plug in the mammary gland hole; a scale scale is fixed on the front of the main board, the scale scale is located between the head hole and the mammary gland hole, and there are semicircular grooves for arms on both sides of the scale scale; the front side of the main board A wedge-shaped pad is provided on both sides of the middle part of the board; a solid cylindrical support is provided on the back of the main board. Compared with the prior art, the present invention provides a flexible fixation method for prone and supine radiotherapy for patients with tumors in the head, neck, shoulder, chest and abdomen, saves economic costs and improves the curative effect of radiotherapy for patients.

Description

technical field [0001] The invention relates to a medical device for fixing a patient's body position, in particular to a multifunctional radiotherapy body position fixing frame. Background technique [0002] In the radiotherapy fixers for tumors in the head, neck and shoulders, chest, and abdomen, the body position fixers usually selected are relatively single. Most of the body position fixation frames are only suitable for supine position fixation, without considering the displacement of the patient caused by the breast compression caused by the patient’s prone position fixation; although a few body position fixation frames take into account the breast compression, they do not better solve the problem of maintaining the head, neck and back of patients in the prone position. In a relative level of the problem, there is no better solution to the breathing problem of the patient in the prone position. For patients with breast cancer with axillary lymph node metastasis and on...

Problems solved by technology

[0002] In the radiotherapy fixation frame for head, neck, shoulder, chest, and abdomen tumors, the body position fixation frame usually selected is relatively single

Most of the body position fixation frames are only suitable for supine position fixation, without considering the displacement of the patient caused by the breast compression caused by the patient’s prone position fixation; although a few body position fixation frames take into account the breast compression, they do not better solve the problem of maintaining the head, neck and back of patients in the prone position. In a relative level of the problem, there is no better solution to the patient's breathing problem in the prone position

For patients with breast cancer with axillary lymph node metastasis and one side resection after surgery, the influence of the external contour of the chest wall in the prone position on the dose of the posterior axillary field has not been better resolved during the body position fixation process.

[0003] At present, in the radiotherapy of head, neck, shoulder, chest, and abdomen tumors, due to the influence of the above problems, there are two posture fixation techniques used: one is to use a supine position fixation frame, choose a suitable headrest, and let the patient lie on his back Located on the body position fixing frame, the body position is fixed with a thermoplastic body film. The disadvantage of this type of body position fixation is that the body position fixation does not have too much flexibility and choice

The disadvantages of this fixed position are: 1. The head and neck are not on the same plane, and the patient’s head and neck cannot adapt to long-term treatment

2. Two sets of body position fixing frames are required, which greatly increases the economic cost

3. Due to the different treatment positions of different patients, it is necessary to constantly replace the position fixation frame, which increases the workload of radiotherapy technicians

The disadvantages of this fixed position mainly include the following points: 1. The chest on the healthy side of the patient is compressed, causing discomfort to the patient and resulting in positional movement

2. The patient's head and neck are poorly fixed and highly mobile, making it difficult to keep on a plane

3. For patients with mastectomy on the affected side, due to the influence of the shape of the thorax, even if the armpit is clamped with a triangular foam pad, it is difficult to ensure that the back and the armpit shoulder and arm are on the same plane during irradiation, which affects the irradiation dose of the axillary lymph nodes, thereby affecting radiotherapy. curative effect
