Description

Technical Field

[0001] The invention relates to the field of operating table structures, and in particular to a head support structure and an operating table. Background Art

[0002] Eyes are an extremely fragile and functionally critical part of the human body, so eye surgery requires extremely high stability and precision. Even under deep anesthesia, a patient's slight movement due to external stimuli, unconscious reactions, or physiological reflexes may instantly disrupt the balance of the surgical area, leading to some serious consequences, which in turn affects the patient's vision recovery and even the quality of daily life.

[0003] When doctors perform eye surgery on patients, they need to use a headrest to fix the patient's head. When the position needs to be adjusted during surgery, the existing head fixation mechanism can only be simply adjusted up and down, which cannot meet the diverse adjustment needs. In addition, in an emergency, the entire operating table is locked and the motor cannot run. The patient's head needs to be quickly moved away from the treatment area to avoid harm to the patient's body. Summary of the invention

DETAILED DESCRIPTION

[0033] A specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation.

[0034] Embodiment 1

[0035] like Figures 1 to 6 As shown, a head support structure provided by an embodiment of the present invention comprises a head support 1, a multi-directional adjustment support, a lifting mechanism and an emergency release mechanism;

[0036] Among them, the multi-directional adjustment support is connected to the headrest 1. The multi-directional adjustment support can provide swing in multiple directions, so that it can be adjusted in a variety of ways according to the intraoperative situation;

[0037] The lifting mechanism is used to drive the multi-directional adjustment support and the headrest 1 to rise or fall. The output end of the lifting mechanism is connected to the lifting plate 2. The multi-directional adjustment support and the lifting plate 2 are respectively equipped with a sliding block 3 and a sliding rail 4 that cooperate with each other;

[0038] The lifting mechanism of this embodiment is a cylinder 5, which is mounted on a cylinder bracket 6. The cylinder bracket 6 is connected to the operating table through an external frame 7. A slider 3 8 is mounted on the external frame 7, and a slide rail 3 9 matching the slider 3 8 is mounted on the operating table.

[0039] The emergency release mechanism is installed on one side of the multi-directional adjustment support, and includes an elastic reset mechanism and a limiter 10. The elastic reset mechanism is slidably arranged on the multi-directional adjustment support, and the limiter 10 is fixedly connected to the lifting plate 2.

[0040] The limiter 10 is located on the path of the elastic reset mechanism moving downward, and can support the elastic reset mechanism and the multi-directional adjustment support. The limiter 10 can be separated from the elastic reset mechanism by the axial movement of the elastic reset mechanism, so that the multi-directional adjustment support and the head support 1 can move downward along the slide rail 4. In an emergency, the head support 1 can be quickly lowered by pressing the spring 12 reset mechanism to avoid damage to the patient's head and eyes.

[0041] The elastic reset mechanism includes a movable block 11, a spring 12, a slider 13 and a slide rail 14. The movable block 11 is connected to an emergency release handle 25. The spring 12 connects the movable block 11 and the multi-directional adjustment support. The slider 13 and the slide rail 14 are respectively connected to the movable block 11 and the multi-directional adjustment support, thereby limiting the movable block 11 to only be able to move horizontally.

[0042] The movable block 11 and the stopper 10 are both provided with a latching tooth portion 15, which has a step surface 16 and an inclined surface 17. In the initial state, the step surfaces 16 of the two latching tooth portions 15 are in contact with each other, and the inclined surface 17 is provided to facilitate the headrest to be reset after an emergency.

[0043] In addition, there is a limit plate 18 below the movable block 11, the limit plate 18 is connected to the multi-directional adjustment support, the lower side of the movable block 11 is threadedly connected to the limit screw 19, and the limit plate 18 is provided with a limit groove 20 that cooperates with the limit screw 19. The limit groove 20 is a bar-shaped hole or a waist-shaped hole. During transportation or other situations where emergency adjustment is not required, the limit screw 19 can be tightened to allow the limit plate 18 to form a fixed connection relationship with the movable block 11, thereby making the emergency release mechanism ineffective;

[0044] In addition, in order to monitor the relative position between the multi-directional adjustment support and the lifting plate 2 in real time, a travel switch 21 is also installed on the lifting plate 2, and a trigger block 26 capable of contacting the contact of the travel switch 21 is installed on the multi-directional adjustment support;

[0045] The multi-directional adjustment support of this embodiment includes a plurality of stacked arc-shaped swing tables 22 and a mounting plate connected to the lowermost arc-shaped swing table 22. The second slide rail 14 is fixed on the mounting plate. The arc-shaped swing table 22 at the lower side is rotated N degrees from the arc-shaped swing table at the upper side, wherein N<180, i.e., any two arc-shaped swing tables 22 are arranged non-parallel, thereby providing diversified adjustment. The arc-shaped swing table 22 is an existing structure, and the driving forms are manual and electric. This embodiment takes the electric arc-shaped swing table 22 as an example.

[0046] In addition, the multi-directional adjustable support is covered with a shell 23, and a clearance slot 24 is opened on the top of the shell 23 to provide sufficient movement space.
