Description

Radiotherapy fixing bracket

Technical Field

The utility model belongs to radiotherapy auxiliary positioning equipment field, concretely relates to radiotherapy fixing bracket.

Background

Breast cancer is the most common malignancy in women, and most patients require radiation therapy. With the advancement of the technology, the current breast cancer radiotherapy method mainly takes shape-adapting and intensity-adjusting and has an obvious trend of replacing the old technologies such as the prior common radiotherapy. At present, during breast cancer radiotherapy, the body position fixation is used for reference by the original method of commonly placing the body position fixation, namely lifting by two hands, lying in a supine position, and adding or not adding an auxiliary fixing system. The specific method comprises the following steps:

(1) lying and lying on the back, lifting with both hands (a breast bracket or a flat bed), fixing the head (with the neck), and unfixing the chest (with the neck). (reference 1, Li bright day main article, therapeutic science of tumor radiotherapy, eighth section (core part at page 1080.). 2, Geqin, etc., research on position fixing technique of radiotherapy after radical improvement of breast cancer, journal of practical tumor.)

(2) Lying supine position, lifting with both hands (breast cradle or flat bed), chest or abdomen fixation, and neck fixation. (reference: 1, Weishi hong et al, comparison of left-side IMRT and 3D-CRT radiotherapy technology dosimetry after radical breast cancer therapy, China tumor prevention and treatment journal.2, Zhangzhong qin, etc., application analysis of different fixing technologies in breast cancer postoperation intensity modulated radiotherapy, latest medical information abstracts in the world.)

(3) Lying on the back, lifting with both hands (breast support or flat bed), and fixing the head, neck and chest. (reference: http:// www.360doc.com/content/17/0524/14/42714521_656762564.shtml)

(4) Lying and lying on the back, lifting the hands and fixing the vacuum pads. (reference 1, Zhangzhong qin, etc., application analysis of different fixing technologies in postoperative intensity modulated radiation therapy of breast cancer, world latest medical information abstracts.2, Geqin, etc., research on the position fixing technology of radiotherapy after improved radical treatment of breast cancer, and a journal of practical tumor).

For breast cancer patients, during radiotherapy, the affected side of the patient lifts the hand and has the following disadvantages:

(1) lateral axillary lymph node dissection is an important component of breast cancer surgery. However, the adverse reactions are edema of the upper limbs and movement disorder of the upper limbs on the affected side. At the same time, most breast cancer patients also need axillary radiotherapy. The radiation therapy causes the aggravation of upper limb edema, upper limb movement disorder and the like on the affected side; and in the short term, aggravated over time. Particularly, with the progress of operations (such as application of endoscopes, surgical robots and the like), the armpit is cleaned more and more cleanly and thoroughly. This also aggravates edema and upper limb movement disorder of the affected side. The breast cancer radiotherapy basically adopts a method of 1 time and 5 times per week (including radiotherapy from Monday to Friday, and saturday and daily rest) for 1 more than about a month. As a result, the lifting ability of the affected upper limb of the patient at the later stage of radiotherapy is obviously reduced compared with that at the beginning of radiotherapy. When in radiotherapy positioning, the upper limbs of the patient can be lifted up normally; however, in the later stage of radiotherapy, in order to lift the upper limb of the affected side, the patient often has the symptoms of obvious forward adduction of the elbow, obvious tension of the muscles of the upper limb and the shoulder joint of the affected side, obvious aggravation of the pain of the shoulder joint and the like compared with the positioning. Even when the positioning is not performed, the position cannot be raised regardless of the effort. This will result in: firstly, the position of the upper arm on the affected side is changed, so that the position of the armpit and the positions of the skin and the subcutaneous tissues in the related area are changed; secondly, the position of the clavicle of the patient is moved, so that the positions of the skin, the upper and lower tissues (particularly lymph nodes) of the clavicle in the area are changed; thirdly, the affected side exerts force and tenses muscles to shorten the chest wall and deform the position; the upper limbs and the chest wall on the affected side exert force to ensure that the affected side of the chest is tensed and forms a certain angle with the neck (when in positioning, the angle between the chest and the neck is close to 0 degree, namely the chest median line and the neck median line are on the same straight line), and integral displacement is generated; fifthly, other displacements. As a result of the displacement, the radiotherapy region deviates from the positioning; the radiotherapy dose distribution is not consistent with the positioning. Individual patients may even need to be repositioned. These all affect the effectiveness of radiation therapy.

(2) The operation and radiotherapy cause edema and dysfunction of the upper limbs on the affected side, and the edema and dysfunction of the upper limbs are aggravated in a short period of time with the lapse of time. In the later stage of radiotherapy, the upper limb of the affected side of the patient is difficult to lift, and shoulder joint pain is obviously aggravated when the upper limb lifts, so that the comfort of the patient is obviously reduced in the later stage of radiotherapy, and the pain of the patient is obviously increased.

(3) Pain may lead to increased respiratory rates in patients, affecting the use of respiratory gating techniques for part of radiotherapy procedures.

(4) The radiotherapy area of breast cancer is chest wall + -lower neck (upper and lower clavicle) + -axilla + -internal breast. Therefore, in most cases, it is necessary to fix the neck and chest of the patient at the same time. However, the current method is to either immobilize the neck, not immobilize the chest; or the chest is fixed and the neck is not fixed; or the head, neck and chest are all fixed (in this case, the head is not necessarily fixed too much). The fixing location is not ideal.
