Description

Technical Field

[0001] The present invention relates to the field of medical devices, in particular to an operating table with adjustable operating positions. Background Art

[0002] During surgical procedures, patient positioning is a crucial step in surgical preparation and is crucial to the smooth progress of the procedure and patient safety. A suitable surgical position not only fully exposes the surgical site and provides the surgeon with an excellent field of vision and space, but also effectively reduces surgical complications and improves patient comfort. While traditional operating tables have played a role in adjusting surgical positioning, their limitations have become increasingly apparent with the continuous advancement of medical technology and the increasing diversification of surgical needs.

[0003] The position adjustment function of traditional operating tables is relatively simple, and can usually only achieve some basic position changes, such as lifting, tilting, etc., and the adjustment accuracy and flexibility are limited. In complex operations, doctors often need to make fine adjustments to the patient's position according to the progress of the operation and operational requirements, such as precisely controlling the specific angles and positions of the head and limbs. However, traditional operating tables are difficult to meet such high-precision adjustment requirements, which may affect the accuracy of the operation due to the doctor's undesirable position during the operation, increasing the difficulty and risk of the operation. For example, in some neurosurgery operations, it is necessary to accurately adjust the angle of the patient's legs. Traditional operating tables can only adjust the patient's legs as a whole. The single adjustment ability of the legs, thighs and calves is insufficient, which may make it difficult for the doctor to accurately reach the target area, thereby affecting the effect of the operation. Therefore, the present invention proposes an operating table with adjustable surgical position. Summary of the Invention

The telescopic end of the first electric telescopic rod 24 is hinged to the main bed board 3 through the cooperation of the hinge block 31 and the slide rail 26. The extension and retraction of the first electric telescopic rod 24 can drive the front bed board 4 to flip up and down, thereby adjusting the supine and prone lying angles of the patient's upper body during surgery; a reinforcement rod 25 is obliquely fixed between the side wall and the bottom wall of the support plate 23 for reinforcing the support plate 23.

[0027] In a further embodiment, the support column 1 comprises an outer shell 21 and an inner shell 22 movably disposed within the outer shell 21. A second electrically-operated telescopic rod 27 is vertically mounted on the bottom of the outer shell 21. The telescopic end of the second electrically-operated telescopic rod 27 is connected to the bottom of the inner shell 22. The main bed board 3 is mounted on the top of the inner shell 22. The base 2 is a disc-shaped structure with a stepped vertical cross-section. By controlling the extension and retraction of the second electrically-operated telescopic rod 27, the inner shell 22 can be raised or lowered relative to the outer shell 21 and base 2, adjusting the overall height of the patient during surgery. In this embodiment, a first connecting ear block 28 and a second connecting ear block 29 are respectively provided on both sides of the top of the inner shell tube 22. The first connecting ear block 28 and the second connecting ear block 29 are respectively provided with at least a pair.

The adjusting rail 9 is set to a semicircular structure. The center of the adjusting rail 9 coincides with the hinge axis of the first rear bed board 5 and the main bed board 3 and the hinge axis of the second rear bed board 6 and the first rear bed board 5. Connecting arms 10 are fixed at both ends of the adjusting rail 9. The connecting arms 10 are fixed on the hinge axis of the first rear bed board 5 and the main bed board 3 and the hinge axis of the second rear bed board 6 and the first rear bed board 5. The first rear bed board 5 and the second rear bed board 6 can flip relative to the adjusting rail 9. A rail is provided on the adjusting rail 9 along a circular arc trajectory. The first and second rear bed boards 5 and 6 are respectively tilted and tilted to adjust the lifting and lowering angles of the patient's lower body during surgery. The first and second rear bed boards 5 and 6 are respectively tilted and tilted to adjust the lifting and lowering angles of the patient's thighs and calves during surgery. The positioning columns 13 are embedded in the corresponding positioning grooves 12, which can position the angle of the first rear bed board 5 or the second rear bed board 6. Pushing the positioning columns 13 into the rail groove 11 can push the first rear bed board 5 and the second rear bed board 6 to flip. The positioning columns 13 are embedded in the positioning grooves 12 at different positions on the adjustment rail 9, which can position the first rear bed board 5 and the second rear bed board 6 at different angles.

[0029] In this embodiment, the radius of the positioning post 13 is smaller than the radius of the positioning slot 12, which facilitates the positioning post 13 being inserted into the positioning slot 12 to angularly position the first and second rear bed boards 5 and 6. A handle 14 is provided at the end of the positioning post 13 away from the first and second rear bed boards 5 and 6, and the adjustment rails 9 are distributed on both sides of the bed body. A cavity 15 is defined within the first and second rear bed boards 5 and 6, and a slider 16 is slidably mounted within the cavity 15. A connecting rod 17 is fixed to one side of the slider 16 and extends through the corresponding side wall of the first or second rear bed board 5 or 6. The positioning post 13 is sleeved and mated with the connecting rod 17. A spring 18 is provided between the slider 16 and the inner end wall of the cavity 15. The spring 18 pushes the slider 16 with its elastic force, causing the connecting rod 17 to drive the positioning post 13 into the positioning slot 12. A pair of first rear bed boards 5 and a pair of second rear bed boards 6 are provided, and a pair of first rear bed boards 5 are hinged side by side at one end of the main bed board 3 away from the front bed board 4, and a pair of second rear bed boards 6 are respectively hinged at one end of a pair of first rear bed boards 5 away from the main bed board 3. The pair of first rear bed boards 5 and the pair of second rear bed boards 6 correspond to the patient's thighs and calves respectively, and the pair of first rear bed boards 5 and the pair of second rear bed boards 6 are respectively flipped up and down and adjusted to adapt to more surgical posture requirements.

[0030] In a further embodiment, an auxiliary plate 8 is hinged on the first rear bed board 5 and the second rear bed board 6. The auxiliary plate 8 can be rotated to be distributed perpendicular to the first rear bed board 5 and the second rear bed board 6. A strap 19 is connected to the auxiliary plate 8. One end of the strap 19 passes through the end face of the auxiliary plate 8 and is connected to an end piece 20. One end of the strap 19 passing through the end face of the auxiliary plate 8 is also provided with a Velcro. Through this structural method, during surgery, the auxiliary plate 8 is rotated to protrude from the surfaces of the first rear bed board 5 and the second rear bed board 6. At this time, the auxiliary plate 8 can block and limit the patient's legs on both sides. Pulling the strap 19 through the Velcro can restrain the patient's legs, creating favorable conditions for the patient's surgery.

[0031] In a further embodiment, hinge blocks 31 are embedded on both sides of the main bed board 3 connected to one end of the first rear bed board 5. The hinge blocks 31 are rotatably connected to the main bed board 3. The first rear bed board 5 is hingedly assembled on the main bed board 3 through the hinge blocks 31. The first rear bed board 5 can be adjusted by flipping up and down relative to the hinge blocks 31 and the main bed board 3. In addition, a pair of first rear bed boards 5 can be horizontally rotated toward both sides of the main bed board 3 through the hinge blocks 31, which can meet the need for the patient to support the body with his legs open during surgery.

[0032] The working principle of the present invention is as follows: during use, the main bed board 3 and the front bed board 4 are hinged, and the telescopic end of the first electric telescopic rod 24 is slidably hinged to the main bed board 3 through the cooperation of the hinge block 31 and the slide rail 26. The first electric telescopic rod 24 is controlled to extend and retract, which can drive the front bed board 4 to flip up and down, thereby adjusting the supine or proximal lying angle of the patient's upper body during surgery;

[0033] The first rear bed board 5 and the second rear bed board 6 are hinged at the other end of the main bed board 3, and the first rear bed board 5 and the second rear bed board 6 are pushed to flip up and down, so as to adjust the lifting and lowering angles of the patient's lower body during surgery. The first rear bed board 5 and the second rear bed board 6 are flipped up and down respectively, so as to adjust the lifting and lowering angles of the patient's thigh and calf during surgery respectively. Among them, the spring 18 elastic force pushes the slider 16 to drive the positioning column 13 on the connecting rod 17 to be embedded in the corresponding positioning groove 12, so as to position the angle of the first rear bed board 5 or the second rear bed board 6. Pushing the positioning column 13 into the rail groove 11 can push the first rear bed board 5 and the second rear bed board 6 to flip, and the positioning column 13 is embedded in the positioning grooves 12 at different positions on the adjustment rail 9, so as to position the first rear bed board 5 and the second rear bed board 6 at different angles.

[0034] By controlling the extension and retraction of the second electric telescopic rod 27, the inner shell 22 can be driven to rise and fall relative to the outer shell 21 and the base 2, thereby adjusting the overall height of the patient during surgery;

[0035] A pair of first rear bed boards 5 can be horizontally rotated toward both sides of the main bed board 3 through the hinge blocks 31, which can meet the need for the patient to be supported in a posture with legs spread during surgery.

[0036] By controlling the lifting and lowering of the third electric telescopic rod 30, and utilizing the hinged connection between the first connecting ear block 28 and the main bed board 3 and the sliding hinged connection between the second connecting ear block 29 and the main bed board 3, the overall pitch angle of the operating bed can be adjusted, thereby adjusting the overall pitch angle of the patient during surgery.

[0037] Therefore, the operating table integrates upper body pitch and tilt angle adjustment, lower body lifting and lowering angle adjustment, separate calf and thigh angle adjustment, overall height adjustment and overall pitch and tilt angle adjustment. It has multi-dimensional adjustment function and high flexibility, which can meet the posture assistance needs of different patients during surgery.
