Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a supine body position fixing device. Background Art

[0002] Radiotherapy after breast-conserving surgery for early breast cancer patients can effectively reduce local recurrence while maintaining organ integrity. Early skin toxicity, radiation pneumonitis, pulmonary fibrosis, glandular fibrosis and other toxic and side effects after radiotherapy for breast cancer are important factors affecting the quality of life of patients. The primary cause of non-breast cancer related death after breast-conserving therapy is radiation-induced cardiovascular events, and secondary lung cancer induced by low-dose random induction effects has become an important cause of death after lung irradiation. The supine position used in clinical practice has always been the most commonly used treatment position for breast cancer radiotherapy, because the patient is more comfortable and well tolerated in the supine position, and the repeatability required for fractionated radiotherapy is also higher.

[0003] In precision radiotherapy, fixing the patient's position can reduce the involuntary movement of the patient's position during radiotherapy, thereby ensuring that the actual irradiation range of the beam is as consistent as possible with the planned target area. At present, in order to ensure the accuracy of breast cancer radiotherapy and prevent dislocation caused by involuntary movements of patients, a breast radiotherapy positioning bracket combined with a position shaping pad (human positioning pad) and a thermoplastic mesh that can transmit radiation is generally used on the treatment bed. However, it can only fix the patient's overall position, not the patient's breast. For some patients with relatively large breasts, especially obese middle-aged and elderly women, their breast skin is loose, their breasts are relatively large and obviously sagging, and the breast tissue has a large range of motion in front of the chest. When the patient is positioned for radiotherapy, even if the head and shoulders are fixed, the relative position of the breast in front of the chest is still not fixed, and respiratory movement will also affect the position of the breast, which can easily cause positioning errors during radiotherapy. Although the prone position can solve the above problems, it will compress the heart and the patient's adaptability and experience are poor. Therefore, most patients still cannot accept the prone position, or cannot persist in the prone position for too long. Moreover, the patient's front cannot be seen in the prone position, which is not conducive to real-time monitoring of whether there are any abnormalities during the patient's radiotherapy.

[0004] Chinese patent CN 113288684 A discloses a breast displacement recovery device for breast patients after surgery, comprising a fixed bottom plate, a first bed plate on the surface of the fixed bottom plate, a second bed plate hinged on the left end of the first bed plate, symmetrically distributed rectangular solid blocks on the front and rear sides of the second bed plate and near the left end, a rectangular hole a is opened in the middle of the top of the rectangular solid block, and a positioning mechanism is movably connected in the rectangular hole a. The breast displacement recovery device for breast patients after surgery can adjust the pitch angle of the patient's upper body through the provided electric cylinder, support rod and second bed plate, which is conducive to the shaping frame to support and position the patient's breast. The provided headrest, first cushion and second cushion can make the patient in a more comfortable state. The provided positioning mechanism can adapt to patients of different body shapes and facilitate the adjustment of the position of the shaping frame by medical staff. However, the device has many parts and a complex structure. Since the radiotherapy process also needs to be covered with a thermoplastic mesh cover, the above structure cannot be well combined with the thermoplastic mesh cover, so it is not suitable for the radiotherapy process.

[0026] Example

[0027] A supine position fixation device, such as Figure 1 As shown, it includes a base plate 1, a thermoplastic mesh 2, and an L-shaped base 3. The L-shaped base 3 is arranged on the base plate 1. The left and right sides of the thermoplastic mesh 2 are respectively installed on the L-shaped base 3. The inner wall of the L-shaped base 3 is respectively provided with telescopic airbags 4 at positions corresponding to the breasts. Two groups of telescopic airbags 4 are simultaneously connected to an external air supply device, and are synchronously extended and retracted. When the telescopic airbags 4 swell, they will generate thrust on the outwardly expanding breasts, causing the breasts to gather toward the middle, thereby adjusting the target area.

[0028] In this embodiment, a positioning device is also included, which is mainly used to position the L-shaped base 3, including a slider 5 and a quick clamp; a slide groove 6 is provided on the side of the base plate 1 in the longitudinal direction, and the slider 5 is provided on the slide groove 6; the quick clamp is provided on the slider 5 and can be moved along the slide groove 6, and can be fixed when moved to a suitable position.

[0029] In this embodiment, the quick clamp includes an angle base 7, an operating handle 8, a telescopic rod 9, a rotating plate 10, and a pressure head 11; the angle base 7 is installed on the slider 5 and can move with the slider 5; the lower end of the operating handle 8 is installed on the lower left part of the angle base 7 through a rotating shaft, and can rotate based on the angle base 7; the right end of the telescopic rod 9 is installed on the upper right part of the angle base 7 through a rotating shaft, and the right end of the telescopic rod 9 is located between the lower parts of the operating handle 8, the telescopic rod 9 can rotate based on the angle base 7, and its left end is connected to the middle part of the pressure head 11; the rotating plate 10 is arranged between the lower parts of the operating handle 8, its upper end is connected to the operating handle 8 through a rotating shaft, and its lower end is connected to the telescopic rod 9 through a rotating shaft. When the operating handle 8 is pressed down clockwise, the operating handle 8 drives the rotating piece 10 to rotate, and the rotating piece 10 drives the telescopic rod 9 to rotate upward, and the pressure head 11 is also lifted up; when the operating handle 8 is lifted counterclockwise, the operating handle 8 drives the rotating piece 10 to rotate, and the rotating piece 10 drives the telescopic rod 9 to rotate downward, and the pressure head 11 is also pressed downward. After the pressure head 11 contacts the L-shaped base 3, the operating handle 8 is continued to be tightened counterclockwise to form a limit between the inner rod and the outer rod of the telescopic rod 9, or bolts can be added to the telescopic rod for fixing.

[0030] In this embodiment, two sets of positioning devices are respectively provided on the left and right sides of the bottom plate 1 to firmly clamp the L-shaped base 3 .

[0031] In this embodiment, an adjustment device is also included, which is used for adjusting the tightness and fixing the thermoplastic mesh 2, and includes a rotating plate 13 and a clamping plate 14; the front and rear ends of the rotating plate 13 are respectively installed on the outside of the L-shaped base 3 through a rotating shaft, and spherical protrusions 15 are respectively provided on the end surfaces of the front and rear ends; the clamping plate 14 is vertically arranged on the bottom inner side of the rotating plate 13; a groove 16 corresponding to the spherical protrusion 15 is provided on the L-shaped base 3, and when the rotating plate 13 is rotated to a vertical position, the spherical protrusion 15 is snapped into the groove 16.

[0032] In this embodiment, a reinforcing plate 17 is also included. The reinforcing plate 17 is vertically arranged at the middle of the inner side of the rotating plate 13. On the one hand, it can strengthen the fixing effect of the thermoplastic web 2, and on the other hand, it plays a certain limiting role on the rotating plate 13 to prevent the rotating plate 13 from excessive rotation.

[0033] In this embodiment, the outer side surface of the vertical plate of the L-shaped base 3 is a curved surface, which is convenient for inserting the thermoplastic mesh 2.

[0034] In other embodiments of the present invention, a belt-shaped airbag 12 is further included. The belt-shaped airbag 12 is arranged in the thermoplastic mesh 2 and is inserted under the patient's breast to play a lifting role and prevent the patient's breast from overlapping with the chest wall. The two ends of the belt-shaped airbag 12 are tied to the mesh of the thermoplastic mesh 4 by a rope to fix and adjust the tightness.

[0035] The working process of the utility model is:

[0036] In the initial state, the telescopic airbag 4 is contracted and attached to the inner side of the L-shaped base 3; when the device needs to be used for radiotherapy of patients, the patient first lies on the bottom plate 1, and then the L-shaped base 3 is placed on the left and right sides of the patient respectively; the quick clamp is moved to a suitable position on the slide 6 by the slider 5, the length of the telescopic rod 9 is adjusted, and then the L-shaped base 3 is fixed.
