Description

Technical Field

[0001] This utility model relates to the technical field of surgical aids for ear scarring, and in particular to an ear fixation device. Background Technology

[0002] Electron beam radiotherapy is commonly used after surgery for keloid scars on the ear, and its effectiveness depends on the precise perpendicularity of the surgical area plane to the radiation beam. Currently, vacuum thermoplastic membranes are the mainstream ear fixation device. These membranes are heated and softened to conform to the patient's head contour, forming a headrest to support the surgical area. However, this technique has significant drawbacks: the fabrication of the thermoplastic membrane requires the operator's experience to complete the entire process of heating, shaping, cooling, and cutting, which is time-consuming and cumbersome; the sharp edges of the cut membrane can easily damage the skin, and in its softened state, it easily adheres to the patient's hair, increasing the difficulty of the procedure. More importantly, the thermoplastic membrane material is soft and lacks sufficient support strength; even slight head displacement can cause the ear support to fail, requiring the use of additional tape for fixation. Therefore, we provide an ear fixation device to address these problems. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an ear fixation device.

[0031] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figure 1 — Figure 7 The example shown.

[0033] This application provides an ear fixing device, which includes two support members 100, a first connecting strap 200, and a second connecting strap 300. Specifically, the two support members 100 are used to support the auricle. Each support member 100 has a first end and a second end. A flexible first metal wire 110 is provided inside each support member 100. The first metal wire 110 is bent to form a support frame adapted to the auricle. The first connecting strap 200 is connected to the first end of the support member 100, and the second connecting strap 300 is connected to the second end of the support member 100. The first connecting strap 200 and the second connecting strap 300 drive the two support members 100 to move closer to each other so that the auricle is in a preset state.

[0034] See Figures 1 to 6 As shown, the two support members 100 are initially positioned at the two auricles of the human head, and then the first connecting strap 200 and the second connecting strap 300 both pass over the human face. Specifically, as shown... Figure 1 and Figure 2 As shown, the first connecting band 200 passes over the forehead and the second connecting band 300 passes over the chin. Under the pull of the first connecting band 200 and the second connecting band 300, the two support pieces 100 move closer to each other. When the patient is lying flat, since the support pieces 100 are located below the auricle, the movement of the two support pieces 100 closer to each other will gradually bring the two auricles into a horizontal state or other angle state, thereby enabling the position of the auricles to meet the requirements of electron beam radiotherapy.

[0035] It is understandable that if the tension exerted by the first connecting strap 200 and the second connecting strap 300 on the two support members 100 is too great, it may deform and detach from the auricle. Therefore, in order to prevent the support member 100 from detaching from the auricle, a first metal wire 110 is provided in the interlayer inside the support member 100. By twisting the first metal wire 110, its shape is adapted to the shape of the auricle. That is, the first metal wire 110 is bent and twisted to form a support frame. The state of the support frame is adapted to the shape of the auricle, so that the shape of the support member 100 is adapted to the auricle and thus fits tightly against the surface skin of the auricle. Since the support member 100 is supported by the support frame made by bending and twisting the first metal wire 110, the support member 100 cannot easily deform at this time, and thus can withstand a large tension without detaching from the auricle due to large deformation. Therefore, the support member 100 improves its stress level through the first metal wire 110 to meet the requirement of the auricle reaching a preset angle or position. In this embodiment, the preset angle of the auricle is a horizontal state.

[0036] The first connecting strip 200 and the second connecting strip 300 are both integral. The first connecting strip 200 is provided with a second metal wire 230, and the second connecting strip 300 is provided with a third metal wire 330.

[0037] See Figure 4 , Figure 5 as well as Figure 6 As shown, in one embodiment of this application, the first connecting strap 200 and the second connecting strap 300 are both integral. It can be understood that the first connecting strap 200 and the second connecting strap 300 are not composed of multiple parts, and both the first connecting strap 200 and the second connecting strap 300 are fixedly connected to the support member 100. In order to ensure the tensile force on the support member 100, both the first connecting strap 200 and the second connecting strap 300 have a sandwich structure. The first connecting strap 200 is provided with a second metal wire 230, and the second connecting strap 300 is provided with a third metal wire 330. In one embodiment, the length of the first connecting strap 200 and the second connecting strap 300 can be adaptively adjusted according to the patient's face shape, face width and other parameters, so as to enable the support member 100 to support the auricle and make the auricle reach a preset angle and position.

[0038] See Figure 2 , Figure 3As shown, in another embodiment provided by this application, the first connecting strap 200 is a split type, the first connecting strap 200 includes a first strap body 210 and a second strap body 220, both the first strap body 210 and the second strap body 220 are provided with a second metal wire 230, the first strap body 210 is connected to the first end of one of the support members 100, the second strap body 220 is connected to the first end of the support member 100 in a direction away from the first strap body 210, and the first strap body 210 and the second strap body 220 are detachably connected by a first buckle 500.

[0039] Please continue reading. Figure 2 and Figure 3 As shown, in order to achieve real-time adjustment of the length of the first connecting strap 200, the first connecting strap 200 is divided into two parts: a first strap body 210 and a second strap body 220. The first strap body 210 and the second strap body 220 are connected by a first buckle 500. It can be understood that the first buckle 500 can connect the first strap body 210 and the second strap body 220 together, or it can separate them. This achieves a separate connection between the first strap body 210 and the second strap body 220.

[0040] In another embodiment, the first buckle 500 includes a first female buckle 510 and a first male buckle 520, wherein the first female buckle 510 is connected to the first belt body 210 and the first male buckle 520 is connected to the second belt body 220; or, the first female buckle 510 is connected to the second belt body 220 and the first male buckle 520 is connected to the first belt body 210.

[0041] In another embodiment, the installation positions of the first female buckle 510 and the first male buckle 520 are not limited, as long as they enable the first belt body 210 and the second belt body 220 to connect. Here, the installation positions of the first female buckle 510 and the first male buckle 520 are illustrated using the former example, that is, the first female buckle 510 is connected to the first belt body 210, and the first male buckle 520 is connected to the second belt body 220. During use, the first male buckle 520 is inserted into the first female buckle 510 to connect the first belt body 210 and the second belt body 220. It can be understood that, in order to accommodate patients with different face shapes or face widths, the positions of the first female buckle 510 and the first male buckle 520 can be adjusted and moved at the positions of the first belt body 210 and the second belt body 220, respectively, thereby changing the overall length of the first connecting belt 200 to accommodate different groups of people.

[0042] In another embodiment, the second connecting strap 300 is a split type, comprising a third strap body 310 and a fourth strap body 320. Both the third strap body 310 and the fourth strap body 320 are provided with a third metal wire 330. The third strap body 310 is connected to the second end of one of the support members 100, and the fourth strap body 320 is connected to the second end of the support member 100 in a direction away from the third strap body 310. The third strap body 310 and the fourth strap body 320 are detachably connected by a second buckle 600.

[0043] Please continue reading. Figure 2 and Figure 3 As shown, in order to achieve real-time adjustment of the length of the second connecting belt 300, the second connecting belt 300 is divided into two parts: a third belt body 310 and a fourth belt body 320. The third belt body 310 and the fourth belt body 320 are connected by a second buckle 600. It can be understood that the second buckle 600 can connect the third belt body 310 and the fourth belt body 320 together, or separate them. This achieves a separate connection between the third belt body 310 and the fourth belt body 320.

[0044] The second buckle 600 includes a second female buckle 610 and a second male buckle 620. The second female buckle 610 is connected to the end of the third belt body 310 facing the fourth belt body 320, and the second male buckle 620 is connected to the end of the fourth belt body 320 facing the third belt body 310; or, the second female buckle 610 is connected to the end of the fourth belt body 320 facing the third belt body 310, and the second male buckle 620 is connected to the end of the third belt body 310 facing the fourth belt body 320.

[0045] In another embodiment, the installation positions of the second female buckle 610 and the second male buckle 620 are not limited, as long as they enable the connection between the third belt body 310 and the fourth belt body 320. Here, the installation positions of the second female buckle 610 and the second male buckle 620 are illustrated using the former example, that is, the second female buckle 610 is connected to the third belt body 310, and the second male buckle 620 is connected to the fourth belt body 320. During use, the second male buckle 620 is inserted into the second female buckle 610 to connect the third belt body 310 and the fourth belt body 320. It can be understood that, in order to accommodate patients with different face shapes or face widths, the positions of the second female buckle 610 and the second male buckle 620 can be adjusted and moved at the positions of the third belt body 310 and the fourth belt body 320, respectively, thereby changing the overall length of the second connecting belt 300 to accommodate different groups of people.

[0046] It should be noted that in actual use, the first connecting belt 200 can be used in combination with the second connecting belt 300 as an integral unit, or the first connecting belt 200 can be used as an integral unit with the second connecting belt 300 as a separate unit. In practice, the choice of which to use is appropriate and no specific limitation is made here.

[0047] To further support the support member 100, a fitting member 400 is fixedly installed on the inner side of the bottom surface of each support member 100, and the fitting member 400 fits against the skin at the auricle position.

[0048] See Figures 1 to 7 As shown, the fitting 400 is located on the bottom inner side of the support 100, and the fitting 400 should fit the human skin below the auricle. The fitting 400 and the support 100 are integrally set, which can reduce the separation of the support 100 from the auricle to a certain extent.

[0049] To further improve the overall strength of the fitting component 400, a fourth metal wire 410 is provided in the fitting component 400. The fourth metal wire 410 is bent under force to form a support frame that fits against the skin of the auricle.

[0050] In this embodiment, it should be noted that the fourth metal wire 410 is bent to form a shape that fits the shape of the skin below the auricle, so that the fitting member 400 fits the skin fully and supports the support member 100, providing sufficient support for the support member 100 to support the auricle.

[0051] In this application, the support member 100, the first connecting strap 200, the second connecting strap 300, and the fitting member 400 can all be made of fabric, such as non-woven fabric. The support force is mainly provided by the shape of the first metal wire 110 and the fourth metal wire 410 after bending. Compared with the existing thermoplastic film, the molding is simple and the material is offset, making the processing simple. In practice, the shape of the entire fixing device can be referenced from the existing mask shape. The difference is that the support member 100 and the fitting member 400 adapted to the ear are set at the ear loop position.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
