[0018] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
[0019] Example
[0020] The present embodiment describes a level for lumbar surgery, such as Figure 1 As shown, it includes a panel 5, a front side wall of the panel 5 is provided with a mounting hole that is connected to the front and rear, the mounting hole is a circular structure, an adjustment ring 7 is provided in the mounting hole, which is limited to free rotation along the center line of the hole, the center line of the adjustment ring 7 is on the same straight line as the center line of the mounting hole, and a level bubble 1 is installed in the adjustment ring 7; a scale line showing an angle is provided on the front side wall of the panel 5 corresponding to the edge of the mounting hole, and an indication arrow pointing to the scale line is provided on the front side wall of the adjustment ring 7; the extension line of the indication arrow is vertically arranged with the level bubble 1;
[0021] like Figure 1 and Figure 4 As shown, the panel 5 is a square structure, the center line of the mounting hole is on the same straight line as the center line of the panel 5, the mounting hole is a circular structure, an adjusting ring 7 is arranged in the mounting hole, and the outer ring wall of the adjusting ring 7 is provided with limiting grooves distributed along its circumference, and the adjusting ring 7 is independently sleeved with a limiting ring 14 limited in the limiting groove, the outer ring of the limiting ring 14 is fixed on the hole wall of the mounting hole, and the adjusting ring 7 is limited to rotate freely in the mounting hole by the limiting ring 14, the center line of the adjusting ring 7 is on the same straight line as the center line of the mounting hole, and the adjusting ring 7 rotates with the center line of the mounting hole as the center point of rotation;
[0022] The two ends of the level bubble 1 are connected to the inner ring of the adjustment ring 7 and are located in the middle of the adjustment ring 7; the scale lines are distributed at the edge of the mounting hole, a total of 360 degrees, and the indicating arrow is engraved on the front side wall of the adjustment ring 7 and points to the scale lines. The 0 scale line of the scale line is located at the top of the mounting hole, that is, the position of 12 o'clock on the clock. The extension line of the tail of the indicating arrow is in a vertical state with the level bubble 1. Under normal conditions, when the level bubble 1 is horizontal, the indicating arrow points to the 0 scale of the scale line. Of course, as the adjusting ring 7 rotates, the direction of the indicating arrow will also change;
[0023] like Figure 2 and Figure 4As shown, a plug-in board 11 for inserting into a plug-in frame 13 is fixed on the rear side wall of the panel 5. The plug-in board 11 is in a "7" shape. The plug-in frame 13 is mounted on the plug-in board 11, and a mounting plate 12 is fixed on the rear side wall of the plug-in frame 13. This section as a whole constitutes a mounting assembly for mounting the panel 5 on the operating table. During installation, the mounting plate 12 is fixed to the side wall of the operating table by four screws distributed in a rectangular shape to avoid space occupation affecting the operation. The plug-in board 11 can be inserted into the plug-in frame 13 and in close contact to avoid shaking of the panel 5 during use.
[0024] In addition, mutually attracted positioning magnets may be embedded in the insert frame 13 and on the insert plate 11 to reduce the shaking of the insert plate 11 when it is inserted into the insert frame 13. Through the cooperation between the insert plate 11 and the insert frame 13, the installation and connection between the panel 5 and the operating table can be easily realized.
[0025] like Figures 1 to 3 As shown, the panel 5 includes a lower combined plate, the top of which is connected to a detachable upper combined plate, and the insert frame 13 is fixed to the rear side wall of the upper combined plate; a connecting plate 2 is fixed to the left side wall of the lower combined plate, a first hinge column 3 is fixed to the top of the connecting plate 2, two hinge rings 4 distributed front and back are fixed to the left side wall of the upper combined plate, and the front and rear ends of the first hinge column 3 are independently installed in the hinge ring 4; two hinge blocks 10 distributed front and back are fixed to the right side wall of the lower combined plate, and hinge holes communicating front and back are opened on the hinge blocks 10, and the same second hinge column is independently installed in the two hinge holes, and a stud 9 perpendicular to the second hinge column is fixed on the side wall, and the upper A locking plate is fixed on the right side wall of the combination plate, and an open groove is provided on the right side wall of the locking plate. The upper end of the stud 9 independently passes through the open groove and is connected with a nut 8 threadedly matched therewith; the left side wall of the upper combination plate and the lower combination plate are hingedly connected by the cooperation between the connecting plate 2, the first hinge column 3 and the hinge ring 4; the right sides of the upper and lower combination plates are locked and connected by the stud 9 and the nut 8. When in use, the stud 9 can be swung out of the open groove after loosening the nut 8, so that the connection between the upper and lower combination plates can be opened, so that the adjustment ring 7 can be removed from the mounting hole for easy cleaning and disinfection; the limit ring 14 is disconnected according to the separation between the upper and lower combination plates;
[0026] like Figure 4 As described, a threaded hole communicating with each other is provided between the top of the panel 5 and the hole wall of the mounting hole, a locking screw 6 threadedly matched with the panel 5 is installed in the threaded hole, an opening is provided on the limit ring 14 corresponding to the threaded hole, and the top tightening end of the locking screw 6 independently passes through the opening and rests on the outer ring of the adjusting ring 7; the threaded hole is located between the top of the upper assembly plate and the mounting hole; when in use, the locking screw 6 can be rotated to lock the adjusting ring 7, the purpose of which is to prevent the adjusting ring 7 from rotating and lock the adjusting ring 7 at a certain angle;
[0027] In actual use, the adjusting ring 7 is adjusted adaptively according to the different positions of the operating bed. Under normal circumstances, the indicating arrow on the adjusting ring 7 points to the 0 scale of the scale line, the level bubble 1 is in a horizontal state, and the operating bed is in a horizontal state. When it is necessary to adjust the angle of the head of the operating bed or the bed position, the panel 5 is installed at the corresponding position of the operating bed. For example, if it is necessary to adjust the head of the operating bed to be tilted to 30 degrees, the adjusting ring 7 is first rotated to make the indicating arrow point to the 30-degree position of the scale line, and the level bubble 1 will tilt accordingly. Then the head of the operating bed is adjusted to tilt so that the level bubble 1 returns to the horizontal position again. When the level bubble 1 is in a horizontal position again, it means that the head of the operating bed is tilted by 30 degrees. In this way, the tilt angle of the operating bed can be conveniently adjusted according to the needs of the operation; and the adjustment angle is relatively accurate to a certain extent. It should be noted that when the swing direction of the head of the operating bed is counterclockwise during the angle adjustment, the indicating arrow pre-points to 30 degrees, but when the swing angle of the head of the bed is clockwise, the adjusting ring 7 should be reversely rotated to 330 degrees during pre-adjustment. The specific situation should be determined according to the actual situation on site.
