The task of the operating room nurse is to ensure the safety of the patient's operation, cooperate with the surgeon, create the best conditions for the patient's treatment, and complete the coordination and rescue work of various surgeries in various departments in a timely, accurate and high-quality manner.

[0003] For example, the Chinese patent with the publication number "CN219700431U" announced "A limb fixation frame for nursing patients in operating rooms", whose main structure includes a mounting base, the top of which is fixedly connected to an electric push rod, the top of which is fixedly connected to a balance board, multiple sets of fixing frame bodies are arranged below one side of the balance board, the top of which is fixedly connected to a cross board, one side of the mounting base is hollowed out, and the top of the hollowed-out part of the mounting base is fixedly connected to a bottom plate. The limb fixation frame for nursing patients in operating rooms is provided with a bottom plate, a clamping plate, fastening bolts, a knob, a block, a sleeve and a sleeve rod. The clamping plate is balanced and stable during movement and use, and shaking is prevented, thereby improving the safety of use. The problem is that the stability of the clamping plate itself is poor, and it is easy to tilt and shake during the clamping and fixing process, resulting in insufficient firmness, which has certain safety hazards, and the overall clamping degree is limited.

The bolt holes 4 of the main fixed base plate 1 are fixedly installed on the periphery of the side beam of the operating bed by bolts to realize the fixed installation of the equipment.

[0026] To achieve a tightening clamping effect on the limb, see Figure 1 , Figure 2 , Figure 3 and Figure 4, it is necessary to set up an elastic tightening clamping mechanism 5, which is internally provided with a rubber base 53 located above the L-shaped connecting plate 2 and capable of supporting the bottom area of ​​the patient's limb, a tightening belt 56 that passes over the rubber base 53 and can perform a close-fitting clamping effect on the top area of ​​the patient's limb, and a coil spring 513 that can exert downward elastic pressure on one end of the tightening belt 56, thereby increasing the clamping strength of the tightening belt 56 on the patient's limb. The patient's limb is inserted between the rubber base 53 and the tightening belt 56, and then the upward pulling force on the tightening belt 56 is released. Under the elastic action of the coil spring 513, the tightening belt 56 will be tightened downward, so that the limb is tightly clamped between the rubber base 53 and the tightening belt 56, thereby achieving a tightening clamping and fixing effect on the limb.

[0027] For the specific structure of the elastic tightening clamping mechanism 5, please refer to Figure 3 and Figure 4, including a transverse connecting substrate 51, a No. 1 rod body fixing groove 52 is arranged at the bottom center of the transverse connecting substrate 51, a rubber base 53 is arranged at the center of the upper surface of the transverse connecting substrate 51, in order to achieve a buffering contact effect, it is necessary to make the rubber base 53 made of a rubber material with an elastic buffering function, and an inner concave structure and a groove structure for placing a limb are arranged on the upper surface of the transverse connecting substrate 51, a belt body fixing plate 54 is fixedly installed on one side of the rubber base 53 on the upper surface of the transverse connecting substrate 51, and a movable belt body fixing plate 54 is arranged on the other side of the rubber base 53 on the upper surface of the transverse connecting substrate 51 The upper end surfaces of the belt fixing plate 54 and the belt movable plate 55 are embedded with a tightening belt 56. In order to improve the air permeability at the skin, the tightening belt 56 needs to be woven from a breathable textile fabric. The bottom of the horizontal connecting base plate 51 is provided with a longitudinal hollow shell 57 with an integral structure therewith. The interior of the longitudinal hollow shell 57 is provided with a cylindrical component movable cavity 58. The horizontal connecting base plate 51 is provided with a No. 1 rod body through hole 59 connecting its upper surface and the top of the cylindrical component movable cavity 58. The bottom end of the longitudinal hollow shell 57 is provided with a connecting space below it and the cylindrical component movable cavity 58. The second rod body through hole 510 at the bottom end, the longitudinal hollow shell 57 is provided with an inner movable plate 511 which can move axially along the cylindrical component movable cavity 58, and the bottom end of the inner movable plate 511 is fixedly installed with a longitudinal limit rod 514 which passes through the second rod body through hole 510 and can move axially along the second rod body through hole 510, and the upper end surface of the inner movable plate 511 is fixedly installed with a longitudinal telescopic rod 512 which passes through the first rod body through hole 59 and is fixedly installed at the bottom of the belt movable plate 55. In order to prevent the component from rotating, it is necessary to make the structure of the cross section of the first rod body through hole 59 external The shape is consistent with the structural appearance of the cross-section of the longitudinal telescopic rod 512, both of which are polygonal structures, and the structural dimensions of the cross-section of the No. 1 rod body through-hole 59 match the structural dimensions of the cross-section of the longitudinal telescopic rod 512. The longitudinal telescopic rod 512 is provided with a coil spring 513 on the outer periphery of the rod body located inside the movable cavity 58 of the cylindrical component. In order to achieve continuous elastic clamping, it is necessary to make the initial length of the coil spring 513 greater than the depth of the movable cavity 58 of the cylindrical component, and one end of the coil spring 513 abuts against the top end of the movable cavity 58 of the cylindrical component, and the other end abuts against the upper surface of the inner movable plate 511.

[0028] For adaptive clamping angle adjustment, see Figure 1 , Figure 2 , Figure 5 and Figure 6, it is necessary to set up a ball-hinged connection mechanism 6, which is internally provided with an annular fixing block 61 fixedly installed in the L-shaped connecting plate 2, a ball head 67 installed in the annular fixing block 61 and capable of limiting the angle between the annular fixing block 61 and the annular fixing block 61 after being filled with gas, and a longitudinal connecting rod 68 that rotates with the ball head 67 and is fixedly connected to the transverse connecting base plate 51.

[0029] For the specific structure of the ball-joint connection mechanism 6, please refer to Figure 5 and Figure 6 , including an annular fixing block 61, the outer circumferential surface of the annular fixing block 61 is provided with an annular fixing groove 62 with an inner concave structure and fixedly installed inside the central fixing port 3, the center of the annular fixing block 61 is provided with a spherical installation cavity 63 with upper and lower ports both in an open state, the annular fixing block 61 is provided with an annular gas storage cavity 64 on the periphery of the middle area of ​​the spherical installation cavity 63, the annular fixing block 61 is provided with an annular elastic gas membrane 65 at the intersection of the spherical installation cavity 63 and the annular gas storage cavity 64, and the bottom of the annular fixing block 61 is provided with A gas flow channel 66 is provided which is connected to the annular gas storage chamber 64 and has an air valve installed inside. The annular fixing block 61 is provided with a rotatable ball head 67 inside the spherical mounting chamber 63. In order to prevent the components from detaching, it is necessary to match the structural radius of the spherical mounting chamber 63 with the structural radius of the ball head 67. The caliber of the upper and lower ports of the spherical mounting chamber 63 is smaller than the structural diameter of the ball head 67. A longitudinal connecting rod 68 is fixedly installed on the top of the ball head 67, and the top end of the longitudinal connecting rod 68 is fixedly installed inside the No. 1 rod body fixing groove 52.

[0030] When in use, the bolt holes 4 of the main fixed base plate 1 are fixed to the outer periphery of the side beam of the operating bed by bolts, the patient's limbs are inserted between the rubber base 53 and the tightening belt 56, and then the upward pulling force on the tightening belt 56 is released. Under the elastic action of the coil spring 513, the tightening belt 56 will be tightened downward, so that the limbs are tightly clamped between the rubber base 53 and the tightening belt 56. When the limb fixation is completed and the clamping angle of the equipment meets the patient's comfortable angle during surgery, the inflation device can be used to fill gas into the valve core. Under the action of the gas pressure, the annular elastic air film 65 is deformed inwardly, thereby increasing the friction between the annular elastic air film 65 and the ball head 67 to ensure that the ball head 67 is at a fixed angle, thereby achieving the necessary component fixing effect.
