Description

Technical Field

[0001] The utility model relates to the technical field of tumor radiotherapy, in particular to a tumor radiotherapy frame which is easy to position. Background Art

[0002] In precision radiotherapy, treatment position and position fixation are extremely important parts of the treatment plan. In order to ensure the accuracy and repeatability of the treatment, a radiotherapy frame is needed to fix the patient's position during radiotherapy, which can ensure that the patient's position remains consistent during each treatment, thereby improving the accuracy of the treatment.

[0003] In the prior art, the common position for abdominal tumors is lying flat. When positioning, the patient needs to lie on the radiotherapy bed, and the patient's abdomen and chest are positioned using a thermoplastic film. After radiotherapy, the patient may experience side effects such as fatigue, lack of energy, loss of appetite and vomiting, which leads to weight loss in the patient. During the course of radiotherapy, multiple radiotherapy treatments are required to achieve the treatment effect. However, the weight loss of the patient is not in line with the radiotherapy frame, resulting in a larger size of the radiotherapy frame. The patient will feel uncomfortable during the treatment process and it is easy to cause inaccurate positioning, affecting the treatment effect. In the case of a large gap between the radiotherapy frame and the patient's body, it is more common to use soft filling materials (such as foam pads) to fill the gap so that the thermoplastic film fits the patient's body contour better. Due to the large differences between patients, the filling materials cannot be reused. Due to the differences in the weight changes of patients, the thickness and size of the filling materials required for each radiotherapy after the weight loss of the same patient may be different, which increases the cost of radiotherapy for the patient. Therefore, the present application provides a tumor radiotherapy frame that is easy to position to meet the needs. Utility Model Content

[0034] like Figures 1 to 5 As shown, an embodiment of the utility model provides a tumor radiotherapy frame that is easy to position, including a supporting airbag 1, a connecting tube is arranged on the supporting airbag 1, the connecting tube is connected to the airbag inflator, the bottom of the inner wall of the supporting airbag 1 is fixedly connected to the limiting frame 2, the top of the limiting frame 2 is fixedly connected to a plurality of supporting spring plates 3, the tops of the plurality of supporting spring plates 3 are all fixedly connected to the supporting frame 4, both sides of the inner wall of the limiting frame 2 are fixedly connected to a plurality of connecting spring plates 8, one ends of the plurality of connecting spring plates 8 are all fixedly connected to the side walls of the supporting frame 4, the connecting spring plates 8 are V-shaped structure, the opening of the V-shaped structure faces the top position of the limiting frame 2, and the two sides of the inner wall of the supporting airbag 1 are respectively fixedly connected to the two sides of the limiting frame 2 and the two sides of the supporting frame 4.

[0035] By using the supporting airbag 1, the limiting frame 2, the supporting shrapnel 3 and the supporting frame 4 in coordination, the patient can use the thermoplastic film to fix the body during the first radiotherapy. In the subsequent radiotherapy process, the radiotherapy frame can be used according to the patient's weight loss. The radiotherapy frame is placed on the radiotherapy bed, and the supporting airbag 1 is inflated and expanded by the airbag inflator through the connecting pipe. At this time, the patient lies on the supporting airbag 1, and the limiting frame 2, the supporting shrapnel 3, the supporting frame 4 and the supporting airbag 1 cooperate to support and position the patient's body. The thermoplastic film positioning frame is installed on the patient's chest, and then the supporting airbag 1 is considered to be inflated or deflated according to the wrapping situation of the thermoplastic film positioning frame and the patient's body, so as to achieve the goal of fixing the patient's body after the patient loses weight. The effect of filling the gap between the body and the thermoplastic film positioning frame can quickly and effectively position the patient's body, so that the thermoplastic film positioning frame fits the patient's body contour better and improves the radiotherapy effect, and the limiting frame 2, the supporting spring piece 3, the supporting frame 4 and the supporting airbag 1 cooperate to adapt to different patients, reducing the cost of radiotherapy for patients. The arranged connecting spring piece 8 improves the connectivity between the limiting frame 2 and the supporting frame 4, and the connecting spring piece 8 is in a V-shaped structure, with the opening direction toward the top position of the limiting frame 2, so that the connecting spring piece 8 is inwardly retracted toward the middle position along the sides of the supporting frame 4 and the limiting frame 2 when deformation occurs, and the connecting spring piece 8 will not contact the patient's body, further improving the comfort of the supporting airbag 1 when in use.

[0036] like Figures 1 to 3 As shown, the two sides of the support airbag 1 are connected in sequence with a first arc-shaped protrusion 13 and a second arc-shaped protrusion 14, the inner wall of the first arc-shaped protrusion 13 is fixedly connected to the side wall of the support frame 4, and the inner wall of the second arc-shaped protrusion 14 is fixedly connected to the side wall of the limit frame 2.

[0037] The first arc-shaped protrusion 13 and the second arc-shaped protrusion 14 are respectively fixedly connected to the two ends of the support frame 4 and the two ends of the limit frame 2, and one side of the cross section at the middle position of the support airbag 1 is a smooth arc-shaped structure, the support frame 4 and the support airbag 1 are adapted to each other, and the arc-shaped structure is adapted to the back of the patient after lying down, which improves the comfort of using the support airbag 1. The first arc-shaped protrusion 13 and the second arc-shaped protrusion 14 improve the connection degree between the support airbag 1 and the limit frame 2 and the support frame 4, and improve the stability of the support airbag 1 and the limit frame 2 and the support frame 4 during use. The multiple second lightweight holes 7 and the multiple first lightweight holes 5 opened on the limit frame 2 reduce the weight of the limit frame 2. The multiple first lightweight holes 5 simultaneously divide the two ends of the limit frame 2 into multiple ones, which can be segmentedly connected with the two sides of the patient's body, so that the two ends of the limit frame 2 are better fitted with the two sides of the patient's body.

[0038] like Figure 3As shown, a plurality of first lightweight holes 5 are provided on both sides of the limit frame 2, a plurality of second lightweight holes 7 are provided on the bottom of the limit frame 2, the limit frame 2 includes a connected base plate and a pair of limit plates, the connection between the limit plate and the base plate is an arc-shaped structure, a weakened groove 6 is provided on the inner wall of the arc-shaped structure, and one end of the limit plate is a spherical structure.

[0039] By setting the weakened groove 6, when the patient lies on the supporting airbag 1, the two sides of the patient's body abut against the two sides of the inner wall of the supporting airbag 1 and the two ends of the limiting frame 2. The limiting frame 2 is an elastic structure. The weakened groove 6 makes it easy for the two ends of the limiting frame 2 to elastically deform, so as to abut against the two sides of the patient's body. The limiting frame 2 includes a bottom plate and a pair of limiting plates to be connected. One end of the limiting plate is a spherical structure. When abutting against the two sides of the patient's body, it cooperates with the second arc-shaped protrusion 14 to better wrap the patient's body without causing any harm to the patient's body.

[0040] like Figures 2 to 5 As shown, the support frame 4 includes multiple groups of first fixing frames 9 and two groups of second fixing frames 10, and one end of the two groups of second fixing frames 10 close to the side wall of the limiting frame 2 is an arc-shaped structure, and one side of the cross section at the middle position of the support airbag 1 is a smooth arc-shaped structure. The support frame 4 is adapted to the support airbag 1, and the support spring clip 3 includes multiple groups of first abutting spring clips 11 and two groups of second abutting spring clips 12. The first abutting spring clip 11 includes multiple connected V-shaped structures, and the bending parts of the V-shaped structures are provided with deformation grooves. The second abutting spring clip 12 has the same structure as the first abutting spring clip 11. Multiple groups of first fixing frames 9 are fixedly connected to the limiting frame 2 through the first abutting spring clip 11, and each group of second fixing frames 10 is fixedly connected to the limiting frame 2 through the second abutting spring clip 12. The thickness of the second abutting spring clip 12 is greater than the thickness of the first abutting spring clip 11, and the thickness of the second abutting spring clip 12 close to the arc-shaped structure is less than the thickness of the second abutting spring clip 12 away from the arc-shaped structure.

[0041] By using the support frame 4 and the support spring sheet 3 in cooperation, when the patient lies on the support airbag 1, a certain pressure is generated on the support frame 4, and the support spring sheet 3 is in a compressed state. The support frame 4 includes multiple groups of first fixing frames 9 and two groups of second fixing frames 10. The multiple groups of first fixing frames 9 and the two groups of second fixing frames 10 are composed of multiple blocks, so that the support spring sheet 3 has a modular structure and can be adapted to different patients. The multiple groups of first fixing frames 9 are fixed by multiple first abutting spring sheets 11 and the limiting frame 2, and the two groups of second fixing frames 10 are fixed by multiple second abutting spring sheets 12 and the limiting frame 2. The plurality of first fixing frames 9 and the two second fixing frames 10 are fixed, that is, each block in each of the plurality of first fixing frames 9 and the two second fixing frames 10 is connected to the limiting frame 2 through the first abutting spring sheet 11 and the second abutting spring sheet 12, respectively. The plurality of first fixing frames 9 are distributed at the middle position of the supporting airbag 1, and the second fixing frames 10 are distributed at the positions on both sides of the supporting airbag 1. The distribution of the first abutting spring sheet 11 and the second abutting spring sheet 12 corresponds to the first fixing frame 9 and the second fixing frame 10, respectively, and the thickness of the second abutting spring sheet 12 is greater than the thickness of the first abutting spring sheet 11, so that under the same pressure, the elastic force generated by the deformation of the second abutting spring sheet 12 is greater. Due to the elastic force generated by the deformation of the first abutting spring sheet 11, the elastic force of the second abutting spring sheet 12 drives the second fixing frame 10 to abut against both sides of the patient's body, and the elastic force of the first abutting spring sheet 11 drives the first fixing frame 9 to abut against the middle position of the patient's back, further improving the supporting effect on the patient and the fit with the patient's body, thereby improving the effect of filling the gap between the patient's body and the thermoplastic film positioning frame. At the same time, the thickness of the arc-shaped structure of the second abutting spring sheet 12 close to the supporting airbag 1 is less than the thickness of the second abutting spring sheet 12 of the arc-shaped structure away from the supporting airbag 1, that is, at the same Under pressure, the elastic force generated by the deformation of the second abutting spring piece 12 of the arc-shaped structure far away from the supporting airbag 1 is greater than the elastic force of the second abutting spring piece 12 at the arc-shaped structure close to the supporting airbag 1, and cooperates with the second fixing frame 10 so that the abutting force of the second fixing frame 10 on the patient's waist is greater than the abutting force on both sides of the patient's ribs, which can better support the patient's waist and further improve the fit between the patient's waist and the thermoplastic film fixing frame. The ends of the two groups of second fixing frames 10 close to the side walls of the limiting frame 2 are in an arc-shaped structure and are adapted to both sides of the patient's body, further improving the comfort of the radiotherapy frame when in use.

[0042] The working principle provided by the utility model is that during the first radiotherapy of the patient, the thermoplastic film can be used to fix the body. During the subsequent radiotherapy, the radiotherapy frame can be used according to the patient's weight loss. The radiotherapy frame is placed on the radiotherapy bed, and the airbag inflator is used to inflate the support airbag 1 through the connecting pipe. At this time, the patient lies on the support airbag 1, and the limit frame 2, the support spring piece 3, the support frame 4 and the support airbag 1 cooperate to support and position the patient's body. The thermoplastic film positioning frame is installed on the patient's chest, and then the support airbag 1 is considered to be inflated or deflated according to the wrapping situation of the thermoplastic film positioning frame and the patient's body. When the patient loses weight, the gap between the patient's body and the thermoplastic film positioning frame is filled, and the patient When lying on the supporting airbag 1, a certain pressure is generated on the supporting frame 4. At this time, the supporting spring piece 3 is in a compressed state. The supporting frame 4 includes multiple groups of first fixing frames 9 and two groups of second fixing frames 10. The multiple groups of first fixing frames 9 and the two groups of second fixing frames 10 are composed of multiple blocks, so that the supporting spring piece 3 has a modular structure and can be adapted to different patients. The thickness of the second abutting spring piece 12 and the first abutting spring piece 11 are different. At the same time, the thickness of the second abutting spring piece 12 on the same straight line is different, so that the elastic force of the second fixing frame 10 is different. The abutting force of multiple 10 on different parts of the patient's body is different, which cooperates with the limiting frame 2 and the supporting airbag 1 to better support the patient's waist.
