Description

Technical Field

[0001] This utility model relates to the field of pillow technology, and in particular to a head-lifting support pillow for operating tables. Background Technology

[0002] Operating table headrests are devices specifically designed to support a patient's head during surgery. They are typically installed at the head of the operating table to ensure that the patient's head remains stable and in the correct position throughout the procedure. The design of the headrest is intended to meet a variety of needs, ensuring that the patient feels as comfortable as possible during long surgeries, reducing discomfort caused by improper positioning or pressure, thereby minimizing unnecessary head movement during surgery and avoiding situations that may affect the surgical process.

[0003] Existing operating tables use fixed headrests, but for some patients undergoing lumbar surgery who need to lie face down, it can be inconvenient. Therefore, a height-adjustable headrest for operating tables was designed to make it convenient for patients to use whether lying down or face down. Summary of the Invention

[0004] To address the aforementioned problems, this utility model proposes a headrest for operating tables that provides a more precise solution.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model discloses a headrest for an operating table, comprising a support frame, a headrest body, a separation mechanism, and two lifting mechanisms. The headrest body is slidably installed within the support frame. The lifting mechanisms are used to adjust the height of the headrest body. The bottom of the headrest body and the bottom inner wall of the support frame are fixedly connected by the lifting mechanisms. A face contour hole is provided at the top center of the headrest body. A filling plate is slidably installed in the face contour hole. When the headrest body moves downward, the separation mechanisms drive the filling plate downward and separate it from the headrest body. The face contour hole provides space for the face when the head is facing down and allows for ventilation.

[0007] Furthermore, the lifting mechanism includes a first rotating plate, a second rotating plate, and a telescopic rod. The first rotating plate and the corresponding second rotating plate are arranged crosswise and rotatably connected. The top end of the first rotating plate is rotatably connected to the bottom of the support body, and the bottom end of the second rotating plate is rotatably connected to the bottom inner wall of the support frame. A round rod is fixedly installed on one side of the second rotating plate, and a rectangular frame is slidably fitted on the outer side of the round rod. One end of the telescopic rod is fixedly connected to the corresponding rectangular frame, and the telescopic rod is fixedly connected to the bottom inner wall of the support frame.

[0008] Furthermore, rollers are rotatably mounted on the bottom end of the first rotating plate and the top end of the second rotating plate. An annular groove is provided on the outer side of the rollers. Two guide plates are fixedly installed on the bottom of the pillow body and the bottom inner wall of the support frame. The rollers are rotatably connected to the corresponding guide plates.

[0009] Furthermore, the separation mechanism includes rack one, rack two, and gears. Two long plates are fixedly installed at the bottom of the pillow body. The gears are rotatably connected to the corresponding long plates. A square hole is opened on the bottom inner wall of the support frame. Rack two is fixedly connected to one side inner wall of the square hole. Rack one is fixedly connected to the bottom of the filling plate. Both rack one and rack two mesh with the corresponding gears.

[0010] Furthermore, the inner wall of the facial aperture is provided with several airway grooves, and the bottom of the airway grooves is open.

[0011] Furthermore, an auricle plate is fixedly installed on the outer side of the filling plate, and two auricle grooves are formed on the inner wall of the facial aperture, with the auricle plate slidably installed in the corresponding auricle groove.

[0012] Furthermore, the top of the pillow body and the filling plate are provided with a recessed section and two protruding sections. The recessed section and the two protruding sections make the top of the pillow body curved, which is used to fit the head. The front side of the pillow body has two relief grooves, and the top, bottom and front side of the relief grooves are all open.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By coordinating two lifting mechanisms, the height of the pillow body can be adjusted to meet the needs of patients who need to slightly raise their heads when lying flat, as well as the requirement that the pillow be at the same height as the operating table when patients are lying prone, so that the height of the pillow can be adapted to different surgical needs.

[0015] 2. The design incorporates facial contour holes, ear grooves, and ventilation holes to enhance patient comfort while lying prone and meet their ventilation needs. Furthermore, the separation mechanism allows the filling plate to move downwards relative to the pillow body when it descends and retracts into the support frame, thereby opening the facial contour holes and vertical grooves, reducing adjustment steps and facilitating practical use.

[0022] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0023] Please refer to Figures 1-4 This utility model proposes a head-lifting pillow for an operating table, comprising a support frame 1, a pillow body 2, a separation mechanism 6, and two lifting mechanisms 3. The pillow body 2 is slidably installed inside the support frame 1. The lifting mechanisms 3 are used to adjust the height of the pillow body 2. The bottom of the pillow body 2 and the bottom inner wall of the support frame 1 are fixedly connected by the lifting mechanisms 3. A facial contour hole 4 is opened at the center of the top of the pillow body 2. A filling plate 5 is slidably installed in the facial contour hole 4. When the pillow body 2 moves downward, the separation mechanism 6 drives the filling plate 5 to move downward and separate it from the pillow body 2. The facial contour hole 4 provides space for the face when the head is facing down and allows for ventilation.

[0024] like Figure 4 As shown, the lifting mechanism 3 includes a rotating plate 7, a rotating plate 8, and a telescopic rod 12. The rotating plate 7 and the corresponding rotating plate 8 are arranged crosswise and rotatably connected. The top of the rotating plate 7 is rotatably connected to the bottom of the pillow body 2, and the bottom of the rotating plate 8 is rotatably connected to the bottom inner wall of the support frame 1. A round rod 9 is fixedly installed on one side of the rotating plate 8, and a rectangular frame 10 is slidably fitted on the outer side of the round rod 9. One end of the telescopic rod 12 is fixedly connected to the corresponding rectangular frame 10, and the telescopic rod 12 is fixedly connected to the bottom inner wall of the support frame 1. Rollers are rotatably installed at the bottom of the rotating plate 7 and the top of the rotating plate 8. An annular groove is opened on the outer side of the roller. Two guide plates 13 are fixedly installed on the bottom of the pillow body 2 and the bottom inner wall of the support frame 1, and the roller is rotatably connected to the corresponding guide plate 13.

[0025] It should be noted that the telescopic rod 12, through the cooperation of the rectangular frame 10 and the round rod 9, converts the lateral movement of the rectangular frame 10 into the swing of the rotating plate 2 8, thereby synchronously driving the rotating plate 1 7 to swing, and thus adjusting the height of the pillow body 2; the setting of the roller and the guide plate 13 makes the swing of the rotating plate 1 7 and the rotating plate 2 8 more stable, and makes the lifting and lowering of the pillow body 2 more stable.

[0026] like Figure 4 As shown, the separation mechanism 6 includes rack 14, rack 2 15, and gear 16. Two long plates 17 are fixedly installed at the bottom of the pillow body 2. Gear 16 is rotatably connected to the corresponding long plate 17. A square hole 18 is opened on the bottom inner wall of the support frame 1. Rack 2 15 is fixedly connected to one side inner wall of square hole 18. Rack 14 is fixedly connected to the bottom of filling plate 5. Both rack 14 and rack 2 15 are meshed with the corresponding gear 16. When the pillow body 2 moves downward, it simultaneously drives the filling plate 5 to move downward synchronously with the pillow body 2, and simultaneously drives the long plate 17 and gear 16 to move downward synchronously. When gear 16 moves downward along rack 14, it drives itself to rotate. Gear 16 drives rack 2 15 to move downward through its rotation, so that the downward distance of filling plate 5 is greater than the downward distance of pillow body 2, thereby separating filling plate 5 from pillow body 2, thus exposing facial contour hole 4, so that the patient can place their face in facial contour hole 4 when lying prone.

[0027] like Figure 3 As shown, several airway grooves 21 are provided on the inner wall of the facial aperture 4. The bottom of the airway grooves 21 is open. When the pillow body 2 moves downward and is retracted into the support frame 1, the filling plate 5 moves downward simultaneously until its top is below the inner wall of the top of the vertical groove, so that the air below the pillow body 2 can enter the facial aperture 4 through the vertical groove, which is convenient for the patient to breathe.

[0028] An auricular plate 19 is fixedly installed on the outer side of the filling plate 5. Two auricular grooves 20 are opened on the inner wall of the facial hole 4. The auricular plate 19 is slidably installed in the corresponding auricular groove 20. The auricular groove 20 is designed so that the patient's ear can be placed in the auricular groove 20 when lying prone, thereby improving the patient's comfort when lying prone.

[0029] like Figure 1As shown, the top of the pillow body 2 and the filling plate 5 is provided with a concave section 22 and two protruding sections 23. The concave section 22 and the two protruding sections 23 make the top of the pillow body 2 curved, which is used to fit the head and improve the comfort of the patient when lying flat. Two relief grooves 24 are opened on the front side of the pillow body 2. The top, bottom and front of the relief grooves 24 are all open. The concave section 22 allows the ear to be placed in the concave section 22 when the patient lies on his side, so that it will not be squeezed by the head and cause discomfort. The relief grooves 24 help support the area between the ear and the shoulder, keep the head and neck in a natural alignment, help reduce the pressure on the neck muscles, and prevent neck discomfort or pain caused by prolonged side lying.

[0030] The working principle of this utility model is as follows: the support frame 1 is fixedly connected to the head of the operating table, so that the front side of the pillow body 2 abuts against the surface of the operating table, as described in the instruction manual. Figure 1 As shown, at this time, part of the pillow body 2 extends out of the support frame 1, and the top of the pillow body 2 is higher than the operating table, which makes it easier for the patient to lie flat. Slightly raising the head can help maintain the opening of the airway and prevent the tongue or soft tissue from falling back and causing airway obstruction. The raised pillow helps maintain the natural curve of the cervical spine and reduces neck muscle tension or pain caused by long-term surgery.

[0031] The telescopic rod 12 drives the rectangular frame 10 to move to one side, thereby driving the pillow body 2 to move downward and retract into the support frame 1 through the lifting mechanism 3. At this time, the top of the pillow body 2 is flush with the operating table. In the prone position, if the head is raised too high, it may increase the pressure on the chest and abdominal organs, affecting respiratory function or cardiac output. Keeping the pillow at the same height as the operating table can reduce these risks. Moreover, for spinal surgery or other back surgery, it is very important to keep the patient's body in a plane, which can ensure that the skeletal structure is in a natural state, which is conducive to the accuracy and safety of the operation.

[0032] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
