[0024] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the solution of the present invention will be further described below. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0025] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] The auricle turning fixator will be described in detail below through specific embodiments:

[0027] As Figure 1 and Figure 2 shown, an auricle turning fixator provided by the present invention includes a first clamping arm 1, a second clamping arm 2 and a fixing device 3. The first end of the first clamping arm 1 and the second end of the second clamping arm 2 are fixedly connected.

[0028] The second end of the first clamping arm 1 is provided with a first clamping ring 11. The first clamping ring 11 is fixedly connected to the first clamping arm 1, and the first clamping ring 11 is bent towards the second clamping arm 2 at a first set angle.

[0029] The first end of the second clamping arm 2 is provided with a second clamping ring 21. The second clamping ring 21 is fixedly connected to the second clamping arm 2, and the second clamping ring 21 is bent towards the first clamping arm 1 at a second set angle.

[0030] The fixing device 3 is detachably connected to the first clamping arm 1 and the second clamping arm 2, and the fixing device 3 is used to maintain the clamping state of the first clamping arm 1 and the second clamping arm 2.

[0031] The shape and size of the first clamping arm 1 described above may be the same as those of the second clamping arm 2. The first end of the first clamping arm 1 may be welded or integrally formed with the second end of the second clamping arm 2, so that the second end of the first clamping arm 1 and the first end of the second clamping arm 2 are opened at a certain distance for clamping the patient's auricle. Further, a first clamping ring 11 is provided at the second end of the first clamping arm 1, and the first clamping ring 11 may be welded or integrally formed with the first clamping arm 1. Similarly, the second clamping ring 21 may also be welded or integrally formed with the second clamping arm 2. Further still, the first clamping ring 11 is bent towards the second clamping arm 2 at a first set angle. The second clamping ring 21 is bent towards the first clamping arm 1 at a second set angle. That is to say, both the first clamping ring 11 and the second clamping ring 21 are bent inward at a certain angle to fit the shape of the patient's auricle, so that the first clamping arm 1 and the second clamping arm 2 can be more firmly clamped on the patient's auricle to prevent dropping. Of course, it can be understood that the first clamping ring 11 and the second clamping ring 21 may be annular structures of any shape or flat plate structures, as long as they can play a clamping role. The first set angle and the second set angle can also be set according to specific applications, as long as they can fit the shape of the auricle.

[0032] The above-mentioned fixing device 3 may be any device with a fixing function, as long as it can be detachably connected to the first clamping arm 1 and the second clamping arm 2, so as to facilitate fixing the first clamping arm 1 and the second clamping arm 2 at any position. Specifically, after clamping the auricle, a tie strap can be tied around the middle parts of the first clamping arm 1 and the second clamping arm 2 to maintain the clamping state of the first clamping arm 1 and the second clamping arm 2, which is convenient for the doctor to perform subsequent operations. An expansion column can also be provided between the first clamping arm 1 and the second clamping arm 2, and a positioning buckle is provided on the expansion column. After the first clamping ring 11 and the second clamping ring 21 clamp the patient's auricle, the buckle on the expansion column is adjusted to fix the first clamping arm 1 and the second clamping arm 2 to maintain the clamping state. During the clamping process, the first clamping arm 1 can be clamped in front of the auricle. The second clamping arm 2 is clamped behind the ear, and then the auricular cartilage fulcrum is constructed and fixed by using the auricle structure. After being firmly fixed, the auricle is flipped forward, and the first clamping arm 1 and the second clamping arm 2 are used to maintain this flipped state by their own weights, so that almost the entire back of the auricle can be exposed, meeting the requirements for most auricle, earlobe and posterior ear surgeries.

[0033] The auricle flipping fixator provided by the utility model fixes and connects the first end of the first clamping arm 1 and the second end of the second clamping arm 2. Further, a first clamping ring 11 is provided at the second end of the first clamping arm 1, and the first clamping ring 11 is fixedly connected to the first clamping arm 1. The first clamping ring 11 is bent towards the second clamping arm 2 at a first set angle. A second clamping ring 21 is provided at the first end of the second clamping arm 2, and the second clamping ring 21 is fixedly connected to the second clamping arm 2. The second clamping ring 21 is bent towards the first clamping arm 1 at a second set angle. So that the first clamping ring 11 and the second clamping ring 21 are attached to the patient's auricle, and the patient's auricle is clamped and flipped by the clamping of the first clamping arm 1 and the second clamping arm 2. Then, a fixing device 3 is detachably connected to the first clamping arm 1 and the second clamping arm 2, and the fixing device 3 is used to maintain the clamping state of the first clamping arm 1 and the second clamping arm 2. Therefore, the patient's auricle can be stably clamped and maintained in a flipped state, exposing the surgical field of view, facilitating the doctor to independently perform surgeries on parts such as the back of the ear, earlobe and auricle of the patient, and saving human resources.

[0034] In some other embodiments, the fixing device 3 includes a fixing stud 31 and a fixing nut 32. One end of the fixing stud 31 is fixedly connected to the middle part of the second clamping arm 2, and the other end of the fixing stud 31 passes through the middle part of the first clamping arm 1 and is screwed with the fixing nut 32.

[0035] One end of the above-mentioned fixing stud 31 can be welded to the middle part of the second clamping arm 2. It can be understood that the fixing stud 31 is welded to the side of the second clamping arm 2 close to the first clamping arm 1 and extends towards the first clamping arm 1. The middle part of the above-mentioned second clamping arm 2 refers to the midpoint of the line connecting the first end and the second end of the second clamping arm 2. Of course, it can also be at any position on the line connecting the first end and the second end of the second clamping arm 2 close to the first end or the second end, which can be specifically set according to actual needs. Further, a through hole can be opened at the corresponding position of the first clamping arm 1 so that the end of the fixing stud 31 away from the second clamping arm 2 passes through the first clamping arm 1. It can be understood that the fixing nut 32 is arranged at the end of the fixing stud 31 away from the first clamping arm 1 and is screwed with the fixing stud 31. Thus, the first clamping arm 1 can be moved away from or close to the second clamping arm 2 by screwing the fixing nut 32, so as to adjust the distance between the first clamping ring 11 and the second clamping ring 21 to adapt to the thickness of the auricles of different patients and ensure the comfort of clamping.

[0036] Further, a retaining ring 4 is provided at the end of the fixing stud 31 close to the first clamping arm 1, and the retaining ring 4 is fixedly connected to the fixing stud 31.

[0037] The above retaining ring 4 can be integrally formed with the fixing stud 31, and the retaining ring 4 can be of any shape. It can be understood that the diameter of the retaining ring 4 is greater than that of the fixing stud 31, so as to prevent damage to the equipment caused by over-tightening of the fixing nut 32 and affect the surgical progress. The material of the above fixing device 3 can be the same as that of the first clamping arm 1 and the second clamping arm 2, so as to facilitate the overall disinfection treatment of the auricle turning fixator. At the same time, the weight of the equipment can be ensured to facilitate maintaining the turned state of the auricle.

[0038] Furthermore, threads are formed on the outer peripheral side of the fixing nut 32.

[0039] The setting of the above threads facilitates increasing friction and preventing slipping during the process of screwing the fixing nut 32, which affects the surgery.

[0040] In some other embodiments, the length of the first clamping arm 1 is less than the length of the second clamping arm 2.

[0041] The length of the above first clamping arm 1 refers to the distance between the first end and the second end of the first clamping arm 1. The first clamping arm 1 can be clamped behind the ear, and the second clamping arm 2 can be clamped in front of the ear. Thus, after the auricle is turned over, the second clamping arm 2 can contact the cheek to play a supporting role. At the same time, the fixing stud 31 is exposed behind the ear, which is not only convenient for the doctor to operate, but also the part of the fixing stud 31 protruding from the first clamping arm 1 can avoid pressing on the cheek.

[0042] Further, the first clamping ring 11 is oval. To increase the contact area with the auricle and make the clamping more stable. Of course, the first clamping ring 11 can also be of other shapes, as long as the first clamping ring 11 and the second clamping ring 21 are in contact with and clamp the patient's auricle.

[0043] Furthermore, the diameter of the first clamping ring 11 is greater than the diameter of the second clamping ring 21.

[0044] To increase the clamping stability, the diameter of the first clamping ring 11 can be set to be greater than the diameter of the second clamping ring 21. The diameter of the above first clamping ring 11 refers to the long diameter of the ellipse.

[0045] In some embodiments, the first set angle is 45 degrees and the second set angle is 15 degrees.

[0046] In addition, the arc length of the first clamping ring 11 can be set to one-eighth of the circle with a diameter of 20 mm, and the arc length of the second clamping ring 21 can be set to one-twenty-fourth of the circle with a diameter of 50 mm, so that the first clamping ring 11 and the second clamping ring 21 fit better with the shape of the auricle.

[0047] In some other embodiments, both the first clamping arm 1 and the second clamping arm 2 are elastic steel plates. Thus, when the fixing nut 32 is screwed, the first clamping arm 1 and the second clamping arm 2 can elastically open and close. Of course, the first clamping arm 1 and the second clamping arm 2 can also be alloy materials of other materials, as long as the surgical requirements are met.

[0048] In addition, anti-slip structures 5 are provided on the side of the first clamping arm 1 facing away from the second clamping arm 2 and on the side of the second clamping arm 2 facing away from the first clamping arm 1.

[0049] The above-mentioned protective structure can be a vertical sliding groove opened on the first clamping arm 1 and the second clamping arm 2 to increase friction and facilitate taking. Of course, other anti-slip structures, such as rubber structures, can also be set as long as the surgical requirements are met.
