DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0025] It should be understood that, in the description of the present application, the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, that is, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, unless otherwise specified, "multiple" means two or more.

[0026] like Figure 1-3 As shown, the surgical foot stool of the embodiment of the utility model comprises a pedal 1, a base 2, a driving assembly 3 and two sets of lifting assemblies 4. The base 2 is arranged below the pedal 1. The driving assembly 3 drives the lifting assembly 4 to move up and down, so that the position of the pedal 1 can be raised or lowered.

[0027] The two lifting assemblies 4 are arranged between the pedal 1 and the base 2. The lifting assemblies 4 include a first connecting rod 41, a second connecting rod 42, a hinge 43, a slide rail 44 and a driving rod 45. The middle part of the first connecting rod 41 is hinged to the middle part of the second connecting rod 42, the first end of the first connecting rod 41 is connected to the pedal 1 through the hinge 43, the second end of the first connecting rod 41 is arranged in a slide groove 44a of the slide rail 44, the first end of the second connecting rod 42 is connected to the pedal 1 through the hinge 43, the second end of the second connecting rod 42 is connected to the base 2 through the hinge 43, the side walls of the slide rail 44 on both sides of the slide groove 44a have horizontally extending through holes 44b, the first end of the driving rod 45 crosses the through hole 44b of the slide rail 44, and is hinged to the second end of the first connecting rod 41.

[0028] The driving assembly 3 includes a motor 31, a screw rod 32, a slider 33 and two bearing seats 34. The motor 31 and the bearing seats 34 are both installed on the base 2. The motor 31 is transmission-connected to the screw rod 32. The two bearing seats 34 are arranged at both ends of the screw rod 32. The screw rod 32 is used to drive the slider 33 to move in the horizontal direction. The two side surfaces of the slider 33 are respectively fixedly connected to the second ends of the two driving rods 45.

[0029] When in use, the motor 31 is turned on for forward or reverse rotation, and the slider 33 on the driving screw 32 moves back and forth in a straight line in the horizontal direction, so that the driving rod 45 drives the first connecting rod 41 to slide back and forth in the slide groove 44a of the slide rail 44. Since the middle part of the first connecting rod 41 is hinged with the middle part of the second connecting rod 42, the first connecting rod 41 and the second connecting rod 42 can switch between the retracted state and the expanded state, thereby adjusting the height position of the pedal 1.

[0030] Among them, Figure 1 As shown, the contracted state between the first link 41 and the second link 42 means that the driving rod 45 drives the first link 41 to move leftward in the slide groove 44a of the slide rail 44, and the position of the pedal 1 is lowered. The extended state between the first link 41 and the second link 42 means that the driving rod 45 drives the first link 41 to move rightward in the slide groove 44a of the slide rail 44, and the position of the pedal 1 is raised.

[0031] Based on the above structural setting, smooth lifting and lowering adjustment can be achieved to meet the surgical needs of doctors of different heights.

[0032] In one embodiment, the surgical footstool further includes a control button 5, which is electrically connected to the motor 31 and is configured to control the motor 31 to switch between forward rotation, reverse rotation and stop. It should be noted that the motor 31 has a brake device, and when in the stop state, the brake device locks the drive shaft of the motor 31, thereby preventing the screw rod 32 from rotating.

[0033] Specifically, anti-skid feet 21 are installed around the base 2. The anti-skid feet 21 make the structure of the base 2 placed on the ground stable.

[0034] In one embodiment, the screw rod 32 and the driving rod 45 are located at the same horizontal position, and the driving rod 45 is perpendicular to the screw rod 32. The slide rails 44 of the two lifting assemblies 4 are arranged parallel to each other.

[0035] In one embodiment, the base 2 further has two holes 22 spaced apart from each other, and the holes 22 are rectangular in shape. The holes 22 can reduce the weight of the base 2.

[0036] Specifically, the first ends of the two first connecting rods 41 and the first ends of the two second connecting rods 42 are arranged around the bottom surface of the pedal 1, so that the pedal 1 is subjected to force around and the structure is kept stable.

[0037] Specifically, the second ends of the two first connecting rods 41 and the second ends of the two second connecting rods 42 are arranged around the surface of the base 2, so that the base 2 is subjected to force around and the structure is kept stable.

[0038] Specifically, the pedal 1 and the base 2 are both arranged horizontally. Both sides of the pedal 1 are bent upward to form an outer edge 11. The outer edge 11 can limit the position of the foot on the pedal 1.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
