[0075] In another possible embodiment of the present application, the first jacking rod 2262 and the second jacking rod 2263 are straight rods with adjustable length, and the first jacking rod 2262 and / or the second jacking rod 2263 are preferably second linear drive cylinders, which can be air cylinders, hydraulic cylinders or other linear drive cylinders, and are controlled by the electrical control system and the hydraulic control system.

[0076] The jacking plate 224 in the present application is a metal plate body with high toughness and capable of being bent, and the surface of the side of the jacking plate 224 away from the support base 21 is a upwardly convex arc surface, and the two long side edges of the arc surface of the jacking plate 224 are the two long side edges of the jacking plate 224, so that when the jacking plate 224 is jacked upward by the first linear drive cylinder 2261, the support head plate 221 above the jacking plate 224 can transition along the arc surface at the top of the jacking plate 224, so that the support head plate 221 gradually rises and forms a certain angle with the jacking plate 224, and the height difference between adjacent support head plates 221 is more smoothly connected and transitioned.

[0077] Referring to Figure 3 , Figure 4 and Figure 5 , a recess groove 2241 is formed in the middle of the side of the jacking plate 224 away from the support base 21, the surface of the recess groove 2241 is arc-shaped, the arc of the recess groove 2241 protrudes downward toward the support base 21, the extension direction of the recess groove 2241 is consistent with the width direction of the jacking plate 224, the recess groove 2241 is formed with at least one recess groove, and the one / multiple recess grooves 2241 are located between the first jacking rod 2262 and the second jacking rod 2263 to provide a recess space for the upward bending of the jacking plate 224.

[0078] The first jacking rod 2262 is hingedly connected to the two sides of the support ball seat 2265 near one end of the first linear drive cylinder 2261, and the second jacking rod 2263 is hingedly connected to the two sides of the support ball seat 2265 near one end of the first linear drive cylinder 2261. One end of the first jacking rod 2262 away from the first linear drive cylinder 2261 is hingedly connected to the jacking plate 224, and one end of the second jacking rod 2263 away from the first linear drive cylinder 2261 is hingedly connected to the jacking plate 224. The hinging axes between the first jacking rod 2262 and the jacking plate 224 and between the second jacking rod 2263 and the jacking plate 224 are parallel to the width direction of the jacking plate 224.

[0079] The operator can control the actual length of the first jacking rod 2262 and the second jacking rod 2263 to bend the jacking plate 224 upward by a certain angle, and the jacking groove 2241 provides a jacking space for the upward bending of the jacking plate 224, so that the head support plate 221 further realizes the height adjustment in front and back on the basis of the elevation adjustment of the support seat 21, so that the head support plate 221 more effectively realizes the support and support of the human head.

[0080] Referring to Figure 5 and Figure 6 The elastic member 227 is preferably a spring in the embodiment of the application. A plurality of springs are uniformly arranged at the four corners of the jacking plate 224 and the two corners outside the edge head support plate 221 of the plurality of head support plates 221. One end of each spring is perpendicularly and fixedly installed on the support seat 21, and the other end is perpendicularly and fixedly installed on the jacking plate 224 / head support plate 221, so as to elastically support the jacking plate 224 and the head support plate 221, cooperate with the jacking power assembly 226, and further enhance the stability of the support seat 21 supporting the head support plate 221 and the jacking plate 224, so that the head support plate 221 can more stably and effectively support the human head.

[0081] Further, in order to make the head support 22 have better support effect on the human body, the first linear drive cylinder 2261 is preferably a gas cylinder, and an overflow valve is installed on each first linear drive cylinder 2261. The opening and closing of the overflow valve is controlled by an electrical control system.

[0082] The operator can control the opening and closing of the overflow valve on the first linear drive cylinder 2261, set the overflow air pressure of the first linear drive cylinder 2261, and control the volume of gas input into the first linear drive cylinder 2261 through the electrical control system, so as to determine whether the first linear drive cylinder 2261 maintains its active driving function as a cylinder to actively jack up the lifting plate 224 or becomes a telescopic rod to passively support the lifting plate 224, so that the multiple head support plates 221 form a circular arc transition that is adapted to the shape of the human head and has smoother connection. When the overflow valve is open and the first linear drive cylinder 2261 is in a deflated state and becomes a telescopic rod, the first linear drive cylinder 2261 in the deflated state can extend / shorten the output shaft length under the pulling action of the first linear drive cylinders 2261 and the lifting plate located on both sides thereof, so that the connection between the lifting plate 224 above the first linear drive cylinder 2261 in the deflated state and the lifting plates 224 on both sides of the lifting plate 224 is smoother. Therefore, the doctor can rotate the patient's head in time according to the needs of the operation during the operation, ensure that the patient's cervical spine and head are properly supported and protected, further reduce the area and possibility of the patient's head being suspended, and enable the patient's head to be adaptively supported at all times.

[0083] The implementation principle of the multifunctional adjustable operating bed controlled by hydraulic pressure in the embodiment of the present application is as follows: during the operation, the operator can first rotate the support 21 relative to the intermediate bed body 3 to adjust the angle of the head bed body 2. When the doctor needs to perform a specific operation of rotating the patient's head, tilting the patient's head to the left or right, etc., the operator can use the electrical control system and the hydraulic control system to drive the first linear drive cylinder 2261, the first jack 2262, and the second jack 2263 in the multiple lifting power assemblies 226, control the telescopic length of the output shaft of each first linear drive cylinder 2261, the telescopic length of the first jack 2262, and the telescopic length of the second jack 2263, drive the lifting plate 224 to lift / lower the head support plate 221, so that the adjacent two head support plates 221 form a certain angle, and make the lifting plate 224 bend upward by a certain angle, so that the head support plate 221 also correspondingly tilts further toward the intermediate bed body 3, thereby reducing the area and possibility of the patient's head being suspended, enabling the patient's head to be adaptively supported at all times, effectively supporting and protecting the patient's head and neck, and effectively avoiding injury to the patient's cervical spine or other adverse effects.
