[0027] Example
[0028] The bed frame (1) is the main area where the patient lies down. Its surface is covered with a soft padding layer, and the material can be soft materials such as sponge or rubber to increase the patient's comfort. Straps can be installed on the sides of the bed frame (1), and the material is sturdy and durable materials such as nylon, to fix the patient during the operation and prevent the patient from moving and affecting the surgical outcome. In addition, the bed frame (1) is also equipped with a headrest, which is adjustable and can be adjusted according to the patient's head position and surgical needs.
[0029] The base (2) is used to support the entire operating table. Its bottom is equipped with an anti-slip pad made of rubber or other materials with good anti-slip properties to ensure the stability of the operating table during use and prevent it from sliding.
[0030] The lifting mechanism (3) is located between the bed body (1) and the base (2). It can be an electric lifting rod or a hydraulic lifting rod, etc., to adjust the height of the bed body (1) to meet different surgical needs and patient comfort.
[0031] The lower connector is a cylinder with a guide stud and two positioning holes arranged at a certain angle around its side. The guide stud and the positioning holes are arranged opposite to each other. The upper connector includes a connecting plate and a cylindrical sleeve. The sleeve is fastened to the lower connector and has a first guide hole that mates with the guide stud and a pull pin that mates with the positioning holes.
[0032] The lower connector (4) is located on top of the lifting mechanism (3). The lower connector is cylindrical, with guide studs (41) and two positioning holes (42) set at a certain angle around its sides. The guide studs (41) are used to cooperate with the upper connector (5) to realize the rotation and positioning of the bed (1). The positioning holes (42) are used to cooperate with the pull pins (53) on the upper connector (5) to ensure the accuracy of the bed (1) during rotation and fixation. Preferably, but not limited to, the included angle between the axes of the two positioning holes (42) is 45°. This design allows the bed (1) to rotate to a suitable position for getting into bed and return to its original position after the patient lies down on the bed.
[0033] The upper connector (5) is located at the bottom of the bed (1) and includes a connecting plate (51) and a sleeve (52).
