DETAILED DESCRIPTION

[0027] The utility model is further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and cannot be used to limit the protection scope of the utility model.

[0028] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example

[0030] like Figure 1 and Figure 2 As shown, the concave lying pillow after vitreoretinal surgery provided by the embodiment of the utility model includes a base plate 201, a first frame 4 and a second frame 5. The first frame 4 and the second frame 5 are symmetrically arranged above the base plate 201 and are inclined.

[0031] A round tube 212 is provided at one end of the first frame 4 located at a high position, and a round rod 213 is provided at one end of the second frame 5 located at a high position. The round rod 213 extends into the inside of the round tube 212. The lower ends of the first frame 4 and the second frame 5 located at a high position are connected to one end of the support rod 202. Figure 3 The other end of the support rod 202 is connected to the slider 204, and the slider 204 is slidably connected to the sliding frame 203. The two ends of the sliding frame 203 are fixed to the side of the bottom plate 201. By moving the slider 204 on the sliding frame 203, the slider 204 can drive the support rod 202 to move, and then drive the first frame 4 and the second frame 5 to move closer to and away from each other. At the same time, the length of the round rod 213 extending into the round tube 212 is also changing. The first frame 4 and the second frame 5 are covered with a soft cover 1. The part of the soft cover 1 located on the round rod 213 and the round tube 212 is a retractable cover, which can prevent the soft cover 1 from being damaged when adjusting the spacing.

[0032] The slider 204 is provided with a fixing mechanism, which is used to fix the position of the slider 204 after adjustment. The fixing mechanism includes a limit ring 206 and a support frame 205. There are multiple limit rings 206, which are evenly arranged on the front side of the bottom plate 201. The side of the sliding frame 203 away from the bottom plate is provided with a support frame 205. The shape of the support frame 205 is an inverted L-shaped as a whole, which includes a horizontal part and a vertical part. Specifically, the horizontal part is connected to the side of the slider 204, and a pull rod 208 is penetrated at the end of the vertical part. The end of the pull rod 208 close to the bottom plate 201 is connected to an insertion rod 211 through a spring 210. The diameter of the spring 210 is larger than the diameter of the pull rod 208. When the pull rod 208 is pulled in a direction away from the bottom plate 201, the spring 210 can be against the vertical part.

[0033] The vertical portion is also provided with a support plate 207, on which a screw 209 is passed, and the end of the screw 209 is threadedly connected to the pull rod 208. The spring 210 can be in a contracted state by fixing the pull rod 208 by the screw 209, and then when the screw 209 is loosened, the spring 210 can push the insertion rod 211 into the limiting ring 206 by elastic force. Example

[0034] On the basis of Example 1, this embodiment further includes an adsorption mechanism, which can fix the entire lying pillow. The number of adsorption mechanisms is 2, which are respectively arranged on both sides of the bottom plate 201, and include a connecting plate 301, which is arranged on the side of the bottom plate 201, and a screw 302 is threadedly connected to the connecting plate 301, and one end of the screw 302 located below the connecting plate 301 is connected to a suction cup 304 through a rotating disk 303, and the suction cup 304 can be adsorbed on the ground to achieve a good fixing effect on the lying pillow.

[0035] The outer wall of the suction cup 304 is connected to a long rod 305, which is inserted into the connecting plate 301, so that the operator can more accurately adjust the position and fixing state of the suction cup, thereby ensuring the overall fixing effect and operation convenience of the prone pillow. When the suction cup needs to be contacted for fixing, the operator can use the long rod to pull the suction cup, thereby playing an auxiliary role.

[0036] The adsorption mechanism is equipped with a desorption mechanism, which is used to release the fixation of the adsorption mechanism to the bottom plate 201, and includes a slide rail 306, which is arranged on the side of the bottom plate 201, and its position is close to the position of the suction cup 304. A connecting frame 307 is slidably connected to the slide rail 306, and the other end of the connecting frame 307 is connected to a plug plate 308, which is wedge-shaped, and its lower end is close to the suction cup 304.

[0037] The working principle of the utility model is as follows: first, when the patient lies on the prone pillow, the distance between the two sides of the prone pillow is adjusted according to the patient's reminder. Specifically, the slider 204 is slid, and the slider 204 drives the support rod 202 to move, thereby driving the distance between the first frame 4 and the second frame 5 to be adjusted. After the adjustment is completed, the screw 209 is rotated to loosen the control of the screw 209 on the pull rod 208. After the spring 210 in the contracted state is loosened, the spring 210 relies on the elastic force to push the insertion rod 211 into the limit ring 206, so that the position of the slider 204 can be fixed, and the distance between the two sides of the prone pillow is adjusted.

[0038] After the patient lies down, the screw rod is rotated, and the screw rod 211 drives the suction cup 304 to move downward. During this process, the air in the suction cup 304 is gradually squeezed out, so that it is adsorbed on the ground, thereby fixing the entire lying pillow.

[0039] After the lying pillow is used, the plug plate 308 is moved toward the suction cup 304 through the connecting frame 307. When the plug plate 308 abuts against the edge of the suction cup 304, the plug plate 308 lifts up the edge of the suction cup 304 to release the fixation of the suction cup 304.

[0040] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
