DETAILED DESCRIPTION

[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] Embodiment 1: This embodiment 1 provides a multifunctional operating table auxiliary head frame, which is directly improved on the existing auxiliary head frame and has a unique structure. Please refer to Figure 1-4As shown, it includes a two-way telescopic mechanism and a U-shaped plate 1 with an opening facing downward, a movable plate 2 is symmetrically installed for sliding in the horizontal direction in the enclosed area of ​​the U-shaped plate 1, the two movable plates 2 are respectively fixedly connected to the output ends of the two-way telescopic mechanism, and two connecting plates 19 are fixedly installed at vertical intervals on adjacent sides of the two movable plates 2; there are various ways to install the movable plate 2, for example: two T-shaped slide grooves are provided at longitudinal intervals on the bottom of the cross plate of the U-shaped plate 1, the two slide grooves are both arranged in the horizontal direction, and T-shaped sliders are symmetrically installed for sliding in the slide grooves, and the two movable plates 2 are respectively fixedly connected to the T-shaped sliders on the same side.

[0018] The bidirectional telescopic mechanism includes a driving mechanism and a bidirectional screw 3, which is connected to the driving mechanism in a transmission manner. The bidirectional screw 3 is installed in a transversely rotatable manner in the enclosed area of ​​the U-shaped plate 1, and the two movable plates 2 are respectively threadedly mounted on the two ends of the bidirectional screw 3; there are various ways to install the bidirectional screw 3, for example: installation grooves are provided on the inner side surfaces of the two vertical plates of the U-shaped plate 1, and bearings are mounted in the installation grooves. Both ends of the bidirectional screw 3 are rotatably connected to the vertical plates of the U-shaped plate 1 through bearings; a cavity is provided in one of the vertical plates of the U-shaped plate 1, and the driving mechanism includes a worm wheel 4 and a worm 5 rotatably installed in the cavity, and the worm wheel 4 and the worm 5 are meshed for transmission, and the bidirectional screw 3 is connected to the worm wheel 4 in a transmission manner, and one end of the worm wheel 4 extends out of the cavity and is mounted with a crank handle 6.

[0019] There are many ways to connect the bidirectional screw 3 and the worm gear 4, for example: one end of the bidirectional screw 3 extends into the cavity and is fixedly connected to the rotating shaft of the worm gear 4 through a coupling, the crank 6 drives the worm 5 to rotate, and then the bidirectional screw 3 is driven to rotate through the meshing transmission of the worm gear 4 and the worm 5. Since the threads at both ends of the bidirectional screw 3 have opposite rotation directions, the bidirectional screw 3 will drive the two movable plates 2 to move closer or farther away from each other when rotating, so that the head frame can be mounted on operating beds of different sizes, increasing the scope of use of the head frame.

[0020] A clamping assembly is provided on the top of the U-shaped plate 1, and the clamping assembly includes an air pump 10 and an arc-shaped fixed frame 7. A first airbag 8 is fixedly installed on the U-shaped plate 1 within the enclosed area of ​​the fixed frame 7. The middle part of the first airbag 8 is recessed inward, which is convenient for placing the patient's head on the first airbag 8 to prevent the patient's head from sliding off the first airbag 8 after the first airbag 8 is inflated. A second airbag 9 is evenly fixedly installed on the inner side surface of the fixed frame 7. The output end of the air pump 10 is connected to an air inlet pipe, and the first airbag 8 and the second airbag 9 are both connected to the output end of the air inlet pipe, and a one-way air inlet valve is provided in the input end of the air inlet pipe, and an exhaust valve 11 is provided in the output end of the air inlet pipe.

[0021] There are many ways to connect the first airbag 8 and the second airbag 9 to the air inlet pipe, for example: a chamber is opened inside the fixed frame 7, the input ends of the first airbag 8 and the second airbag 9 are connected to the chamber, the output end of the air inlet pipe is also connected to the chamber, an exhaust port connected to the chamber is opened on the fixed frame 7, and the exhaust valve 11 is fixedly installed in the exhaust port; a fixed cylinder 12 is fixedly installed on one side of the top of the U-shaped plate 1, a vertical rod 14 is clamped in the fixed cylinder 12, and a cross bar 16 is clamped at the top of the vertical rod 14. There are many ways to clamp the vertical rod 14 and the cross bar 16, for example: a connecting cylinder 15 is fixedly installed on the top of the vertical rod 14 in the horizontal direction, and pipe clamps 13 are installed on the fixed cylinder 12 and the connecting cylinder 15. The vertical rod 14 and the cross bar 16 are respectively clamped in the fixed cylinder 12 and the connecting cylinder 15 through the pipe clamp 13, and the cross bar 16 can be used to support the sterile towel, thereby separating the sterile area and the sterile area.

[0022] When the head frame is in use, the crank handle 6 is first turned, and the crank handle 6 drives the worm 5 to rotate, and then the bidirectional screw 3 is driven to rotate through the meshing transmission of the worm wheel 4 and the worm 5. Since the threads at both ends of the bidirectional screw 3 have opposite rotation directions, the bidirectional screw 3 will drive the two movable plates 2 to move closer to or away from each other when rotating, so that the head frame can be clamped on operating tables of different sizes, thereby increasing the use range of the head frame.

[0023] Then let the patient lie on the operating table and rest his head on the depression in the middle of the first airbag 8, start the air pump 10, and the air pump 10 injects high-pressure gas into the first airbag 8 and the second airbag 9 through the air inlet pipe. The first airbag 8 and the second airbag 9 expand to fix the patient's head. When the first airbag 8 and the second airbag 9 expand to a certain extent, turn off the air pump 10. At this time, the one-way air inlet valve can seal the air inlet pipe to prevent gas backflow; then, the medical staff hangs the sterile towel on the cross bar 16 to separate the sterile area and the sterile area. When the operation is over, press the exhaust valve 11 to discharge the gas in the first airbag 8 and the second airbag 9, thereby releasing the fixation of the patient's head.

[0024] Embodiment 2: Embodiment 2 is different from Embodiment 1 in that Figure 1 As shown, a plurality of pipeline clamps 17 are fixedly installed at intervals along the axial direction on the cross bar 16, and a plurality of rubber pads 18 are fixedly installed at intervals along the longitudinal direction on the movable plate 2 between the two connecting plates 19, which are used to clamp and position the equipment pipelines to prevent the pipelines from falling off.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
