[0029] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked.

[0030] See also Figures 1 to 7 Understand this application.

[0031] An auxiliary device for oropharyngeal surgery includes a pillow 101, which includes a frame 102 and two bearing parts 107 that can respectively bear the back neck and the occipital bone. The two bearing parts 107 are respectively connected to the frame 102 and arranged in an array along a first direction. The two bearing parts 107 can respectively move up and down relative to the frame 102 so that there can be different height differences between the two bearing parts 107.

[0032] See also Figure 1 , Figure 2 In one embodiment of the present application, the frame 102 is further provided with two second guide rails 104 arranged vertically, and the two bearing parts 107 are respectively connected to the two second guide rails 104 and can move up and down along the second guide rails 104 to change the height difference between the two bearing parts 107, see Figure 2 The second guide rail 104 is a telescopic rod, one end of the telescopic rod is connected to the bearing part 107, and the other end is connected to the frame 102, so that the bearing part 107 can move up and down relative to the frame 102 under the guidance of the telescopic rod, so that the two bearing parts 107 have different heights relative to the frame 102, and the two bearing parts 107 can have different height differences. In order to better describe the present application, the bearing part 107 that can bear the back neck is referred to as the first bearing part 108, and the bearing part 107 that can bear the occipital bone is referred to as the second bearing part 109.

[0033] The height of the second bearing part 109 can be lower than that of the first bearing part 108, so that when the patient lies on the operating table, the first bearing part 108 supports the back of the patient's neck, and the second bearing part 109 supports the patient's occipital bone. Since the height of the second bearing part 109 is lower than that of the first bearing part 108, the patient's head will tilt back, thereby fully exposing the oral cavity upwards, so that medical staff can have a better surgical field of view, and the doctor can adjust the height difference between the two bearing parts 107 according to the surgical requirements to meet the surgical needs of different patients.

[0034] Of course, the implementation of the second guide rail 104 is not limited to the telescopic rod, and other structures can also be used as long as they can guide the up and down movement of the bearing part 107.

[0035] Those skilled in the art to which the present application relates can understand that there are various ways to achieve the up and down movement of the two bearing parts 107 along the second guide rail 104 , which are described in detail below.

[0036] See also Figures 1 to 3 In one embodiment of the present application, the two bearing parts 107 are respectively connected with a height adjustment mechanism, which can drive the bearing parts 107 to move up and down along the second guide rail 104 to adjust the height difference between the two bearing parts 107; the height adjustment mechanism is a scissor jack 105 structure, the lower frame of the scissor jack 105 is fixedly connected to the second guide rail 104, and the upper frame of the scissor jack 105 is connected to the bearing part 107. Medical staff can shake the jack screw 110 to adjust the deformation degree of the scissor jack 105, thereby driving the bearing part 107 to move up and down along the second guide rail 104 to change the height of the two bearing parts 107 relative to the frame 102, so that the two bearing parts 107 can have different height differences, so that the patient can have different reclining angles when lying on the operating bed.

Of course, there are other ways to realize the up and down movement of the bearing part 107 along the second guide rail 104, which will not be repeated here.

[0038] In one embodiment of the present application, the frame 102 is further provided with a first guide rail 103, see Figure 1 The extension direction of the first guide rail 103 is the same as the first direction, wherein one of the bearing portions 107 is connected to the first guide rail 103 and can move along the first guide rail 103 to change the distance between the two bearing portions 107 .

[0039] See also Figure 4 The first bearing part 108 is connected to the frame 102 through a telescopic rod, and the second bearing part 109 is connected to the first guide rail 103 through the second guide rail 104. The second guide rail 104 can move along the first guide rail 103, so that the second bearing part 109 can move along the first guide rail 103, changing the distance between the two bearing parts 107, cooperating with the height adjustment mechanism, adjusting the distance between the two bearing parts 107, and adjusting the height difference between the two bearing parts 107 to meet the surgical needs of different patients.

[0045] See also Figure 6 In one embodiment of the present application, the adjustment bracket 201 also includes an opener connecting device 204 connected to the second connecting rod 203, the opener connecting device 204 can fix the David opener 205, the opener connecting device 204 is connected to the second connecting rod 203, and can move along the extension direction of the second connecting rod 203, thereby changing the spatial position of the opener 205. Furthermore, the second connecting rod 203 is cylindrical, and the opener connecting device 204 can rotate around the axis of the second connecting rod 203, thereby changing the spatial posture of the opener 205 connected to the opener connecting device 204.

[0046] Technicians in the technical field to which the present application belongs can understand that a locking structure can be provided between the first connecting rod 202 and the pressure plate 301, between the second connecting rod 203 and the first connecting rod 202, and between the opener connecting device 204 and the second connecting rod 203 in the present application. When the movable components are in a suitable position, the locking structure is used to fix the relative positions of the two movable components, thereby preventing the position of the opener 205 from changing during surgery. The first connecting rod 202 and the second connecting rod 203 are taken as examples below. The locking structure is a bolt and a screw hole. The second connecting rod 203 is provided with a screw hole, and the first connecting rod 202 is provided with a plurality of screw holes along its extension direction.
