[0003] However, the current sterile dressing structure is relatively large, and usually covers the patient's head and shoulders. At this time, the sterile dressing will block the patient's mouth, nose and other positions. When the patient is topically anesthetized or locally anesthetized, the sterile dressing is covered, which can easily cause the patient to have difficulty breathing, hold his breath, and feel uncomfortable, causing increased intraocular pressure, which will affect the progress of the operation. In the prior art, a sterile sheet device (patent announcement number: CN202313773U) is disclosed. The device includes structures such as horizontal supports, vertical supports, supports and stainless steel pipes, which improve the patient's breathing conditions during surgery and ensure the surgical effect. However, the corresponding structure of the device is a fixed connection method, and the height cannot be adjusted for different patients to adapt to the operation; secondly, when the device is not in use, it is directly removed from the operating table and placed in the corresponding space, but because the overall structure is supported by a fixed connection method, it will occupy the corresponding space and is not convenient for storage. Utility Model Content

[0007] In order to fix the support structure on both sides of the operating bed and enable it to rotate, in some embodiments, the side walls of the operating bed are provided with protrusions, and the rotating seat is movably mounted on the protrusions.

[0008] In order to automatically adjust the lifting height of the support frame, in some embodiments, gear teeth are provided on the outside of the lifting rod, and the transmission gear is meshed with the gear teeth of the lifting rod.

[0009] According to an extended solution of the utility model, it is advantageously provided that the support frame includes a cross bar with both ends hingedly connected to each other, so that the support frame can be ensured to have an opening and closing function, and space can be saved.

[0010] In some embodiments, the support frame includes a telescopic cross bar, and the telescopic cross bar can also achieve an opening and closing effect.

[0011] In some embodiments, the left and right ends of the cross bar are respectively hinged with vertical rods.

DETAILED DESCRIPTION

[0029] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. However, it should be understood that the present application can be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. These embodiments are provided here to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0030] In the description of the present application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present application.

[0031] The defects of the prior art that the height cannot be adjusted to match different patients for surgery and that it is inconvenient to store and takes up space. After careful analysis, the inventor found that the reason why the existing structure supporting the sterile cloth has the above problems is mainly that the device is integrally formed, and the disclosed horizontal support is above the patient's face, and it cannot be adjusted downward to make the sterile cloth as close to the patient's face as possible. If this structure is used, the sterile cloth may be far away from the patient's face, and the doctor needs to press down the sterile cloth to perform the operation, which is not very convenient; secondly, the structure of the disclosed prior art sterile cloth device can be removed from the operating table when not in use. However, the structure is integrally formed and cannot be disassembled. It is placed next to the bed or other locations. Due to structural problems, it occupies corresponding space and is not convenient for folding, folding and other storage. Based on the above analysis, the inventor has improved the structure supporting the sterile cloth.

[0032] like Figure 1 As shown, in one embodiment of the sterile cloth support structure of the present application, the support structure includes an operating table 1 and a lifting mechanism arranged on both sides of the operating table 1 and used to support the sterile cloth. The lifting mechanism includes a rotating seat 7 with a cavity. The rotating seat 7 is made into a cavity for the purpose of reducing weight and facilitating rotation. Figure 2As shown, the rotating seat 7 includes a lifting rod fixing cavity 7-1 and a gear cavity 7-2. A transmission gear 11 is provided in the gear cavity 7-2 of the rotating seat 7. A motor 12 connected to the transmission gear 11 is provided on the outer wall of the rotating seat 7. A lifting rod 10 that can move up and down is provided in the lifting rod fixing cavity 7-1 of the rotating seat 7. The support frame is movably arranged on the top of the lifting rod 10 and is used to support the sterile cloth. When not in use, the rotating seat 7 is rotated counterclockwise to rotate the support structure to be parallel to the operating bed 1, and then it can be stored; when in use, the rotating seat 7 is rotated clockwise, and then the height of the lifting rod 10 is adjusted by the motor 12. The support frame can be opened to support the sterile cloth, which is relatively convenient to store and use.

[0033] In order to fix the support structure on both sides of the operating table 1 and enable it to rotate, refer to Fig.10 The side wall of the operating bed 1 is provided with a protrusion 1-1, which is cylindrical and has a circular flange on its end face. The rear end of the rotating seat 7 is provided with a hole matching the protrusion 1-1. The rotating seat 7 is movably mounted on the protrusion 1-1 through the hole. When the support frame is folded, the entire structure can be rotated and laid flat.

[0034] The support frame can adjust its height through the lifting rod 10, and the height of the sterile cloth can be adjusted according to different patients, so as to ensure that the sterile cloth does not fit the patient's face and the tension of the sterile cloth does not affect the doctor's work. Figure 2 and Fig.10 The outside of the lifting rod 10 is provided with gear teeth 10 - 1 , and the transmission gear 11 is meshed with the gear teeth 10 - 1 of the lifting rod 10 .

[0035] In this embodiment, reference Figure 6 The support frame includes a cross bar 5 with two ends hingedly connected to each other, so that the support frame can be opened and closed. Figure 3 As shown, before laying it flat, the support frame is folded up first, which can prevent the support frame from being higher than the top surface of the operating bed 1 and being touched when the operating bed 1 is used, and also plays a certain role in saving space.

[0036] In another embodiment, Figure 8 As shown, the support frame includes a telescopic crossbar 5, which can be supported by a square structure, and its side is provided with elastic protrusions for limiting position, and the telescopic crossbar 5 can also achieve the effect of opening and closing. The telescopic rod is closed and laid flat without taking up space.

[0037] The left and right ends of the crossbar 5 are respectively hinged with vertical rods 3, and the opposite end faces of the two vertical rods 3 are provided with vertical grooves 3-2. Support members are arranged in the two vertical grooves 3-2. The function of the support members is to increase the contact area with the sterile cloth to make the sterile cloth more stable.

[0038] In addition, the position where the lifting rod 10 is connected to the support frame is set to be hinged, so that the support frame can be swung and laid flat. When the cart for placing sterile surgical instruments is far away from the operating bed, or when sterile surgical instruments are frequently taken, it can be used as a pendant or desktop, such as Figure 4-6 As shown, the support member is a grid net 2 or a flat plate 13. When the support member is a grid net 2, some sterile surgical instruments can be placed flat; when the support member is a flat plate 13, some tray-like sterile surgical instruments can be placed. How to make the lifting rod 10 have the function of swinging and laying flat, so as to facilitate the placement of some frequently used sterile surgical instruments, the specific structure is that a cylindrical movable head 10-3 is provided between the connection of the lifting rod 10 and the support frame, the side wall of which is provided with a thread, the bottom is provided with a hinge block 10-4, the left and right sides of the hinge block 10-4 are provided with pins, the top of the lifting rod 10 is provided with a notch, the hinge block 10-4 is swingably arranged in the notch through the pin, the outer wall of the notch is provided with a thread, and a screw sleeve 10-5 is provided at the thread, when the screw sleeve 10-5 is sleeved on the thread of the movable head 10-3 and the outer wall of the notch, the movable head 10-3 is limited by the screw sleeve 10-5 and cannot swing, the screw sleeve 10-5 is rotated downward, and the hinge block 10-4 is exposed, and the movable head 10-3 can swing. Thus, the support frame is driven to swing.

[0039] At the bottom of the cross bar 5, a side wall of the lifting rod 10 is provided with a limit baffle 10-2, more specifically, a side wall of the movable head 10-3 of the lifting rod 10 is provided with a limit baffle 10-2, which is used to limit the downward swing of the hinged cross bar 5.

[0040] In order to prevent the upright pole 3 from swinging to the left and right, refer to Figure 6 and Figure 7 The front and rear end surfaces of the vertical rod 3 are respectively provided with a slide groove 3-1, and a slider 4 is provided in the slide groove 3-1. The front and rear ends of the slider 4 are bent and buckled in the slide groove 3-1, and a protrusion 4-1 is provided at the bottom of the slider 4; a limiting groove is provided on the inner wall of one side where the cross bar 5 and the vertical rod 3 are hinged. When the slider 4 slides along the slide groove 3-1 to the bottom of the vertical rod 3, the protrusion 4-1 is placed in the limiting groove, so that the vertical rod 3 cannot swing to the left or right.

[0041] In order to prevent the rotating seat 7 from excessive rotation, the side wall of the rotating seat 7 is provided with a fixing ring 7-3 with a hole, such as Figure 2 and Figure 8As shown, the side wall of the operating bed 1 is provided with a locking member 6 of a movable locking fixing ring 7-3. The specific structure of the locking member 6 includes a Z-shaped angle iron 6-3 fixedly connected to the operating bed 1 with bolts. A through hole is opened on the front end surface of the angle iron 6-3, and a fixing rod 6-1 is arranged in the through hole. A limiting flange 6-2 is arranged on the outer wall of the fixing rod 6-1. A spring 6-4 is sleeved on the fixing rod 6-1. The front end of the spring 6-4 fits with the end surface of the angle iron 6-3, and the other end fits with the limiting flange 6-2. The side view of the fixing rod 6-1 is T-shaped. Pull up the fixing rod 6-1, and then swing the rotating seat 7 clockwise. The top of the fixing ring 7-3 of the rotating seat 7 contacts with the top surface of the angle iron 6-3, limiting the rotating seat 7 from continuing to rotate. Then release the fixing rod 6-1, and the fixing rod 6-1 squeezes the limiting flange 6-2 through the reaction force of the spring 6-4 to send the fixing rod 6-1 into the hole of the fixing ring 7-3 for limiting.

[0042] The use method or working principle of the support structure is as follows: when not in use, the support structure Figure 3 As shown, it is placed on the edge of the operating bed 1 and supported by the hook 8 hung on the bed rail 9 of the operating bed 1 to prevent it from falling; when in use, the left hand holds the lifting rod 10 to swing clockwise, and the right hand pulls up the fixing rod 6-1. When the fixing ring 7-3 and the angle iron 6-3 of the locking member 6 are in contact, the fixing rod 6-1 is loosened, and the fixing rod 6-1 is placed in the fixing ring 7-3 to limit the support structure to prevent the swinging, and then the support frame is opened, and the slider 5 on the slide groove 3-1 of the vertical rod 3 slides downward until the protrusion 4-1 is inserted into the limiting groove of the cross bar 5 to limit the swinging of the vertical rod 3, and the support member is placed between the vertical rods 3 of the support frame. The support member is limited by the vertical groove 3-2, and sterile cloth is laid on the support frame on the left and right sides of the operating bed 1. According to the specific situation of the patient, the motor 12 drives the gear 11 to drive the lifting rod 10 to rise and fall to a suitable height through forward and reverse rotation.

[0043] In other operations, if there is no need to support the sterile cloth, the screw sleeve 10-5 on the lifting rod 10 can be unscrewed, and after the hinge block 10-4 is exposed, the support frame can be laid flat. When a grid net 2 or a flat plate 13 is placed between the vertical poles 3, it can be used as a pendant or a small table for convenient placement of sterile medical equipment, utensils, etc.

[0044] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the specific embodiments described above based on the concept of the present application should all be within the protection scope of the present application.
