Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and particularly relates to a head and neck radiotherapy fixing device, a bed body and a detection device. Background Art

[0002] Radiotherapy is an important means for treating tumors. Radiotherapy is widely used in the treatment of primary and metastatic head and neck tumors. With the progress of radiotherapy technology, compared with traditional radiotherapy, intensity-modulated radiotherapy better protects normal tissues and organs. For example, the incidence of trismus caused by temporomandibular joint fibrosis has been significantly reduced, and the quality of life of patients after treatment has also been improved. During radiotherapy, it is necessary to accurately locate the lesion to guide high-energy rays to kill tumor cells. There are important organs such as the brainstem, spinal cord, optic chiasm, and eyeballs in the head and neck, and the requirements for radiotherapy accuracy are relatively high. Therefore, during radiotherapy, it is necessary to fix the head, neck, and shoulders of head and neck tumor patients.

[0003] Currently, the commonly used fixing device for head and neck tumor radiotherapy patients is a head, neck, and shoulder thermoplastic integrated film. The production time of this film is relatively long, and the airtight compression feeling after cooling and shrinking brings great discomfort and fear to patients with claustrophobia, making it difficult for them to complete radiotherapy positioning, thus delaying subsequent radiotherapy.

[0004] To solve the above problems, a fixing device with a hollowed-out face has been introduced. However, when the existing fixing device is fixed at the position below the face, it will compress the larynx and neck and requires two layers of the back and chest to be fixed to each other, with a complex structure and inconvenient use. Summary of the Invention

[0005] The embodiments of the present application provide a head and neck radiotherapy fixing device, a bed body and a detection device to solve the problem that when the existing fixing device in the related technology is fixed at the position below the face, it will compress the larynx and neck and requires two layers of the back and chest to be fixed to each other, with a complex structure and inconvenient use.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Apparently, the described embodiments are some, but not all, of the embodiments of this application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0032] The embodiments of this application provide a head and neck radiotherapy fixation device, a bed body, and a detection device, which can solve the problems that when the existing fixation device fixes the position below the face, it will compress the larynx and neck, and requires two layers of back and chest to be fixed to each other, with a complex structure and inconvenient use.

[0033] See Figures 1-3 As shown, in the first aspect of the embodiments of this application, a head and neck radiotherapy fixation device is provided, including:

[0034] A fixation mechanism, which includes a base plate 1, a face fixation member 2 disposed on the base plate 1, and two symmetrically disposed shoulder fixation members 3 disposed on the base plate 1. The shoulder fixation member 3 is a curved surface structure adapted to the shape of the shoulder.

[0035] By providing the shoulder fixation members 3 on both shoulders to tightly fix the shoulders and prevent the patient's body from moving, when the patient turns left or right, they will be limited and fixed by the corresponding shoulder fixation member 3 on that side, which plays a role in fixing the patient, avoiding the use of a large-area pressing structure to press and fix the patient, resulting in an increased sense of compression and discomfort for the patient, and avoiding the setting of a pressing structure on the neck, which may cause breathing difficulties due to neck compression.

[0036] By pressing the face fixation member 2 against the face, the face fixation member 2 is a curved surface structure that conforms to the curve of the patient's face, restricting the rotation of the patient's head. Moreover, both the face fixation member 2 and the shoulder fixation member 3 are disposed on the base plate 1, making the face fixation member 2 and the shoulder fixation member 3 integrally arranged. When the face fixation member 2 and the shoulder fixation member 3 press against the patient's face and shoulder, the movement of the patient's head and body will be restricted, and the face limitation and shoulder limitation cooperate with each other, improving the limitation effect and the fixation effect of the face fixation member 2 and the shoulder fixation member 3.

[0037] The base plate 1 integrally arranges the face fixation member 2 and the shoulder fixation member 3 to cooperate with each other for fixation and limitation, and is connected and fixed through the structure of the base plate 1 in contact with the patient, such as the bed body on which the patient lies or other detection devices, so that the face fixation member 2 and the shoulder fixation member 3 are fixed through the base plate 1, and the face fixation member 2 and the shoulder fixation member 3 press against the patient's face and shoulder.

[0038] Among them, the facial fixing member 2 is preferably made of a soft material such as silica gel for fitting the face for comfort. The shoulder fixing member 3 is preferably made of a hard material such as resin to avoid body movement. The facial fixing member 2 and the shoulder fixing member 3 can also be made of hard materials simultaneously to improve the fixing strength. The fixing mechanism can extract data by scanning the patient with a three-dimensional scanning instrument and be made through three-dimensional modeling, so that the facial fixing member 2 and the shoulder fixing member 3 better conform to the curved surfaces of the patient's face and shoulders.

[0039] In some alternative embodiments, referring to Figures 1-3 As shown, in this head and neck radiotherapy fixing device, a plurality of ventilation holes 10 are provided on both the shoulder fixing member 3 and the facial fixing member 2.

[0040] The use of the ventilation holes 10 can avoid excessive area pressing on the patient, and also avoid sweating or discomfort caused by local enclosure when the patient is fixed for a long time, resulting in the inability to carry out treatment or detection normally.

[0041] In some alternative embodiments, referring to Figures 1-3 As shown, in this head and neck radiotherapy fixing device, the shape of the base plate 1 is adapted to the outer curve shape of the head and shoulders. There are two base plates 1 which are symmetrically arranged on both sides of the head. The base plate 1 includes an upper plate 11 connected to the facial fixing member 2 and a lower plate 12 connected to the shoulder fixing member 3.

[0042] There are two base plates 1, which are symmetrically arranged on both sides of the head. The base plate 1 on the right side of the head among the two base plates 1 on both sides is in an L shape, and the base plate 1 on the left side is a symmetric L shape. The shape of the base plate 1 is adapted to the outer shape of the head and shoulders. An upper plate 11 is provided on one side of the head, and a lower plate 12 is provided on the side of the shoulder close to the head. Through the base plate 1 that is shaped to fit the head and shoulders, and the distance between the two base plates 1 is greater than the width of the head, the base plate 1 is fixed in the corresponding position, and the facial fixing member 2 and the shoulder fixing member 3 are fixed and pressed tightly.

[0043] When in use, it is directly covered from the front of the patient's face, so that the facial fixing member 2 covers the face, and the shoulder fixing member 3 covers the shoulders. Then, the base plate 1 is connected and fixed to the bed body or detection device in contact with the patient, so that the facial fixing member 2 and the shoulder fixing member 3 press the patient tightly.

[0044] In some alternative embodiments, referring to Figures 1-3 As shown, in this head and neck radiotherapy fixing device, a reinforcing rib 13 is provided between the upper plate 11 and the lower plate 12 to strengthen the structural strength between the upper plate 11 and the lower plate 12 and prevent the upper plate 11 and the lower plate 12 from being bent or broken due to accidental shaking by the patient.

[0045] In some alternative embodiments, in the head and neck radiotherapy fixation device, the substrate 1 is in a convex shape. The substrate 1 includes an upper plate 11 disposed at the head and neck and a lower plate 12 disposed at the shoulders. The facial fixation member 2 is disposed on the upper plate 11, and the shoulder fixation member 3 is disposed on the lower plate 12.

[0046] Among them, the substrate 1 can also be integrally provided and in a convex shape. When in use, the patient can be drilled into the space channel formed by the facial fixation member 2 and the shoulder fixation member 3 and the substrate 1, for example, from above the patient's head from top to bottom, so that the patient's head is drilled into the space between the facial fixation member 2 and the shoulder fixation member 3 and the substrate 1, and the face is matched with the facial fixation member 2, and the shoulders are matched with the shoulder fixation member 3. Finally, the substrate 1 is fixed to drive the facial fixation member 2 and the shoulder fixation member 3 to press tightly against the patient.

[0047] In some alternative embodiments, as shown in Figures 1-3 In the head and neck radiotherapy fixation device, a first support plate 4 is provided between the substrate 1 and the facial fixation member 2. One end of the first support plate 4 connected to the facial fixation member 2 is bent so as to form a space for placing the ears between the first support plate 4 and the facial fixation member 2. A second support plate 5 is provided between the substrate 1 and the shoulder fixation member 3. One end of the second support plate 5 connected to the shoulder fixation member 3 is bent so that the shoulder fixation member 3 can be completely pressed and fitted with the shoulders.

[0048] Through the bent end of the first support plate 4, it is possible to avoid the ears being blocked and compressed, resulting in discomfort to the patient, and improve the comfort of the patient. By using the bending of the second support plate 5, the shoulder fixation member 3 can be completely fitted with the shoulders, avoiding the situation where the shoulder fixation member 3 is partially overlapped with the substrate 1 due to the shoulder fixation member 3 being provided on the vertical second support plate 5, resulting in incomplete fitting, fixing, and pressing with the shoulders.

[0049] In some alternative embodiments, in the head and neck radiotherapy fixation device, first inclined plates 7 inclined away from the ears are provided on both sides of the facial fixation member 2. A first support plate 6 is provided between the substrate 1 and the first inclined plate 7. The first support plate 6 is detachably connected to the first inclined plate 7. A second inclined plate 9 inclined away from the shoulders is provided on the side of the shoulder fixation member 3 away from the shoulders. A second support plate 8 is provided between the substrate 1 and the second inclined plate 9. The second support plate 8 is detachably connected to the second inclined plate 9.

[0050] Bolt holes are provided at the joints of the first inclined plate 7 and the first support plate 6. For example, a counterbore with internal threads is provided at one end of the first support plate 6 away from the substrate 1. The first inclined plate 7 and the end of the first support plate 6 away from the substrate 1 overlap, and through holes are provided at the overlapping ends. The first inclined plate 7 and the first support plate 6 are connected by bolts, and the bolts pass through the through holes and are connected to the counterbore. When different patients need to be replaced, only different matching facial fixation members 2 and shoulder fixation members 3 need to be replaced, reducing costs and improving work efficiency and utilization rate.

[0051] The second support plate 8 and the second inclined plate 9 are symmetrical structures of the first inclined plate 7 and the first support plate 6, so they will not be described again.

[0052] In some alternative embodiments, as shown in Figures 1-3 The facial fixing member 2 is provided with hollow openings 21 for exposing the eyes, nose, mouth, and cheeks. Through the hollow openings 21, compression on the patient's face is avoided, a sense of enclosure for patients with claustrophobia is avoided, and the discomfort of the patient is reduced.

[0053] In a second aspect of the embodiments of the present application, a bed body is provided. The bed body is adaptively assembled with the head and neck radiotherapy fixing device. When a patient lies on the bed body, the substrate 1 can be fixed on the bed body. At this time, a first connection hole is provided on the bed body, and a second connection hole corresponding to the first connection hole on the bed body is provided on the substrate 1. The fixing device is fixed on the bed body by connecting the second connection hole with the first connection hole through a bolt.

[0054] In a third aspect of the embodiments of the present application, a detection device is provided. The detection device is adaptively assembled with the head and neck radiotherapy fixing device. When a patient lies or sits on the detection device, the substrate 1 can be fixed on the detection device. At this time, a first connection hole is provided at the corresponding position of the detection device, and a second connection hole corresponding to the first connection hole of the detection device is provided on the substrate 1. The fixing device is fixed on the detection device by connecting the second connection hole with the first connection hole through a bolt.

[0055] The working principle and process of the present application:
