Abstract
Description
Technical Field
[0001] The utility model relates to a fixing device for the healthy hand during breast cancer radiotherapy, belonging to the technical field of medical equipment. Background Art
[0002] Patients undergoing postoperative radiotherapy for breast cancer are fixed in position through a breast positioning frame. Generally, there are two position-fixing methods. One is the position with both hands lifted upwards. The patient's both hands are lifted upwards along the head side simultaneously, and the arms are supported by the bilateral brackets. This requires a certain physical diameter for the CT. Generally, a physical diameter of 70 cm - 85 cm can pass through smoothly. However, many grass-roots radiotherapy units do not have large-bore CTs, and the physical diameter is generally below 60 cm. For overweight patients, as well as many elderly breast cancer patients or patients with severe joint diseases who cannot fully lift one arm upwards, if the position with both hands lifted upwards is adopted, they cannot pass through the CT for scanning and positioning smoothly. The second is the fixed position with the affected side's single hand lifted upwards. The affected side's arm is lifted upwards along the head side, and the arm is supported by the bracket of the affected side's arm, while the healthy side's arm is placed along the body side. Lifting the affected side's hand upwards and translating the breast positioning bracket towards the healthy side can reduce the occupied space and thus increase the scanning passability, and all ordinary diagnostic CTs can pass through smoothly. During breast cancer radiotherapy positioning, it is necessary to mark the centers of three groups of cross lines on the chest and both sides of the body with a special marker pen, and stick lead markers at the three centers, and then perform a CT scan to complete the radiotherapy positioning. When the patient's affected side's arm is lifted upwards, the healthy side's arm needs to be fixed to ensure the repeatability of the treatment position each time, so as to make the position of the body surface marking line consistent with that during radiotherapy, and further ensure the accuracy of radiotherapy. However, when the existing mainstream breast positioning frames place the healthy side's arm along the body side, there is no fixing device for the hand. The patient cannot remember the accurate position, and the technician cannot accurately reset the patient's body surface marking line with the laser lamp, resulting in great difficulty in resetting each time during radiotherapy, affecting the accuracy of radiotherapy and the curative effect of radiotherapy. Content of the Utility Model
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a fixing device for the healthy hand during breast cancer radiotherapy. This device can keep the position of the patient's healthy side's arm consistent during each radiotherapy process, ensure the consistency of the patient's treatment and positioning positions, and improve the accuracy and curative effect of radiotherapy.
[0004] The technical solution adopted by the present utility model to solve its technical problems is as follows: A fixing device for the healthy hand during breast cancer radiotherapy, including a base. The base is in the shape of a U-shaped groove, and the opening of the base is a horizontal opening. On one side of the top plane of the base, there is a support ball. The bottom of the support ball is a flat surface, and a vertical stud A is fixedly connected to the center of the flat surface. At the position corresponding to the support ball, a through hole is provided in the upper plane of the base. The stud A is fitted through the through hole, and the support ball is locked and fixed by a nut on the stud A. On one side of the support ball, two vertically spaced threaded sleeves are fixedly connected to the top plane of the base. A stud B is threadedly connected to each of the threaded sleeves. The top ends of the studs B are fixedly connected with a cross-shaped knob, and the bottom ends of the studs B are each fixed with a pressing plate. A rubber pad I is provided at the bottom of each pressing plate. Below the two pressing plates, a rubber pad II is provided above the lower plane of the base. Between the two studs B, a transparent scale observation window b is provided in the top plane of the base. At the middle position on one side in the length direction of the scale observation window b, a scale pointer B is provided in the top plane of the base. Between the two studs B, a transparent scale observation window a is provided in the vertical surface of the base. At the middle position below in the length direction of the scale observation window a, a scale pointer A is also provided in the vertical surface of the base.
[0005] The beneficial effects of the present utility model are as follows: By recording the scale position of the fixing device for the healthy hand relative to the breast support during radiotherapy positioning of the patient, and letting the patient's healthy hand hang naturally and placing it on the support ball each time during radiotherapy, the healthy arm of the patient can maintain the same position each time, so that the healthy arm of the patient can always ensure the consistency of the position during each radiotherapy process, improving the reset accuracy of radiotherapy, and thus ensuring the effect of radiotherapy. This device needs to be used in conjunction with a radiotherapy breast support and is suitable for most current clinical breast supports. This device has a simple structure, reasonable design, and convenient operation. Description of the Drawings

[0013] As Figure 1 —4 shows, a fixing device for the healthy hand during breast cancer radiotherapy includes a base 1. The base 1 is in the shape of a U-shaped groove, and the opening of the base 1 is a horizontal opening; on one side of the top plane of the base 1, there is a support ball 4. The bottom of the support ball 4 is a plane, and a vertical stud A 3 is fixedly connected to the center of the plane. At the position corresponding to the support ball 4, a through hole 2 is provided in the upper plane of the base 1. The stud A 3 is fitted through the through hole 2, and the support ball 4 is locked and fixed by a nut 5 on the stud A 3; on one side of the support ball 4, two vertically spaced threaded sleeves 6 are fixedly connected to the top plane of the base 1. A stud B 7 is threadedly connected to each of the threaded sleeves 6. The top ends of the studs B 7 are fixedly connected with a cross-shaped knob 8, and the bottom ends of the studs B 7 are each fixed with a pressure plate 9. A rubber pad I 10 is provided at the bottom of each pressure plate 9; below the two pressure plates 9, a rubber pad II 11 is provided above the lower plane of the base 1; between the two studs B 7, a transparent scale observation window b 13 is provided in the top plane of the base 1. At the middle position on one side in the length direction of the scale observation window b 13, a scale pointer B 15 is provided in the top plane of the base 1; between the two studs B 7, a transparent scale observation window a 12 is provided in the vertical surface of the base 1. At the middle position below in the length direction of the scale observation window a 12, a scale pointer A 14 is also provided in the vertical surface of the base 1.
[0014] There are two sets of the fixation device for the healthy hand during breast cancer radiotherapy, one set for each side, left and right, which are symmetric. When in use, it needs to be used in conjunction with the breast support. Select the hand fixation device for the corresponding side according to the healthy side. During the breast cancer radiotherapy process, the affected arm of the patient needs to be lifted and placed on the breast support, and the healthy arm of the patient can be lifted and placed on the breast support or placed at the side of the body according to the treatment situation. When the healthy arm of the patient is selected to be placed at the side of the body, this device is used to limit the position of the healthy hand to ensure that the marking line on the patient's body surface coincides with the laser lamp, so as to ensure the consistency of the radiotherapy position each time and achieve a more effective treatment purpose. For this purpose, the support ball 4 needs to be located below the healthy hand of the patient. The U-shaped groove opening of the base 1 is aligned with the bed body, and the scale on the bed body is observed through the scale observation window a12 or the scale observation window b13. Record the position of the hand fixation device used by this patient according to the scale position indicated by the scale pointer 14. Then, the knob 8 drives the stud B7 to move up and down in the threaded sleeve 6, and the device is fixed and clamped on the bed body by the pressing plate 9 and the lower flat plate body of the base 1. The support ball 4 is located below the hand, and the patient holds the support ball 4 with the hand, so as to ensure that the upper arm and forearm of the healthy arm of the patient are always in a bent state.
[0015] The support ball 4 is designed to be a detachable structure, so that different sizes of support balls 4 can be replaced according to the size of the patient's hand to improve the comfort of the patient when holding the support ball 4. The rubber pad I 10 at the bottom of the pressing plate 9 and the rubber pad II 11 above the lower flat plate body of the base can effectively protect the bed body and prevent the bed body from being damaged when clamping the bed body. The observation window a12 and the observation window b13 are set according to the different scale positions of different bed bodies. Some scales are on the upper part of the bed body, and some scales are on the side of the bed body. The scale on the bed body at different positions can be observed through the scale observation window a12 or the scale observation window b13.
