Description

Technical Field

[0001] This invention relates to the field of operating table equipment, specifically an operating table with adjustable body position. Background Technology

[0002] An operating table is a working platform for doctors to perform surgery on patients. It is an essential medical tool in surgical procedures. During surgery, the operating table supports the patient and can be adjusted in position according to the needs of the operation, providing doctors with a better surgical environment for better surgery. Generally, operating tables can only raise or lower the patient's height, and cannot achieve more angle support states or stop at any position to maintain its angle. This makes it difficult for doctors to operate on certain parts during surgery, increasing the difficulty of the operation. Existing operating tables also have problems such as slow start and stop actions and inaccurate stopping positions, requiring multiple adjustments to achieve the optimal tilt position, wasting valuable surgical time and posing a risk of accidents. Summary of the Invention

[0034] The operating table of this application includes two sets of bed adjustment mechanisms, with a bed assembly fixed between the two mechanisms. Each bed adjustment mechanism includes a robotic arm adjustment assembly and a bed tilting assembly. The robotic arm adjustment assembly adjusts the height of the bed tilting assembly, thereby changing the height of one end of the bed assembly and altering its horizontal height. This allows for height adjustment based on the surgeon's condition and the surgical procedure, improving the surgeon's experience and enhancing surgical outcomes. Furthermore, by changing the state of the two robotic arm adjustment assemblies, the bed assembly can be positioned with one end higher than the other, increasing the surgical positioning options and further enhancing the surgical effect. The bed assembly of this application can be tilted synchronously by the two bed tilting assemblies, allowing for surgery in a lateral position or by changing the patient's position as needed by the surgeon.

[0035] The robotic arm adjustment component and bed tilting component of this application have high space utilization and compact structure, which can flexibly adjust the patient's position while taking into account the overall stability of the operating table. Attached Figure Description

[0069] To make the objectives, technical solutions, and advantages of the present invention clearer, the invention will be described clearly and completely below in conjunction with specific embodiments.

[0070] like Figures 1 to 13 The operating table shown is adjustable in position and includes: two symmetrically arranged bed adjustment mechanisms, a bed assembly disposed between the two bed connection mechanisms, and a connecting beam 500 for connecting the two bed adjustment mechanisms.

[0071] The bed adjustment mechanism includes:

[0072] The base 4 includes a base substrate 4-0 and a base body 4-1 disposed on the base substrate 4-0;

[0073] The support column 1 includes a column body with a C-shaped cross-section, a column base plate 1-4 disposed at the bottom of the column body, a column limiting part 1-1 disposed on one side of the column base plate 1-4, and a cover 1-2. The column base plate 1-4 is fixedly connected to the upper end face of the base body 4-1, and the column limiting part 1-1 protrudes from the column base plate 1-4 and is fixedly connected to the side of the base body 4-1.

[0074] The robotic arm adjustment assembly 2 is disposed on the upper part of the support column 1 away from the column limiting part 1-1. It includes a first robotic arm 2-1 disposed on the support column 1 and a second robotic arm 2-2 disposed at one end of the first robotic arm 2-1. The robotic arm adjustment assembly 2 is used to adjust the height position of the bed tilting assembly 3, thereby changing the height of one end of the bed assembly.

[0075] The bed tilting assembly 3 includes a tilting drive component mounted on one end of the second robotic arm 2-2 and a bed mounting bracket 3-4 mounted on the tilting drive component. (See attached image.) Figure 9 One end of the bed frame assembly is detachably connected to the bed frame mounting frame 3-4; the flipping drive component is used to drive the bed frame mounting frame 3-4 to rotate, thereby driving the bed frame assembly to rotate;

[0076] See details Figures 4 to 6 The plane containing the motion trajectory of the first robotic arm 2-1 is parallel to the plane containing the motion trajectory of the second robotic arm 2-2, and the plane containing the motion trajectory of the first robotic arm 2-1 is perpendicular to the rotation plane of the bed mounting frame 3-4.

[0077] See Figures 4 to 6 When the robotic arm adjustment assembly 2 is in operation, it applies a torque to the top of the supporting column 1, tilting it to one side. The connection and fixation between the column limiting part 1-1 and the base base 4-1 increases the connection strength between them and counteracts the aforementioned torque, thereby increasing the stability of the operating table and reducing its shaking. Furthermore, the column base plate 1-4 is fixed to the side closest to the base base 4-1, and the robotic arm adjustment assembly 2 is located away from the column limiting part 1-1. This ensures that the position of the bed tilting assembly 3 corresponds to the symmetrical plane of the base 4, improving the overall stability of the bed adjustment mechanism, further reducing the shaking of the operating table, making the operation smooth and reliable, and increasing the precision of the surgery. In summary, the bed adjustment mechanism of this embodiment is not only compact and has high space utilization, but also ensures overall stability, showing promising application prospects.

[0078] See Figure 3 , Figure 7 and Figure 8 One end of the first robotic arm 2-1 is connected to the support column 1 via a first motor 2-3, and the other end of the first robotic arm 2-1 is connected to one end of the second robotic arm 2-2 via a second motor 2-4. A third motor 2-5 is located at the other end of the second robotic arm 2-2. The first rotary motor 2-3 is located at the top of the support column 1, the second motor 2-5 is located inside the end of the first robotic arm 2-1, and the third motor 2-5 is located inside the end of the second robotic arm 2-2. In this embodiment, all four sets of motors and their corresponding connection structures adopt flange connections to increase connection stability and reduce shaking.

[0079] See Figures 10 to 12 The flipping drive component includes a flipping support base 3-1, a motor mounting cylinder 3-2 disposed on the flipping support base 3-1, a fourth motor 3-8 disposed within the motor mounting cylinder 3-2, and an adapter 3-3 disposed on the output end of the fourth motor 3-8. A support base connecting plate 3-1-1 is disposed on one side of the flipping support base 3-1, which is connected to the output end of the third motor 2-5. The adapter 3-3 is connected to the bed frame mounting bracket 3-4.

[0080] See Figures 10 to 12 The bed mounting bracket 3-4 is generally H-shaped, with several shaft holes arranged on its long rods. The shaft holes on two long rods face each other for the bed mounting pin 3-5 to pass through. Two adapter wings 3-3-2 are symmetrically arranged on both sides of one end of the adapter 3-3. Each adapter wing 3-3-2 has a wing positioning pin 3-3-21. The adapter 3-3 has a connecting hole corresponding to the bed mounting pin 3-5. (See also...) Figure 13 One end of the long rod of the bed mounting bracket 3-4 is provided with a pin hole corresponding to the wing positioning pin 3-3-21. The bed mounting bracket 3-4 is inserted and installed on the wing positioning pin 3-3-21 through the pin hole. The shaft holes on the two long rods are aligned with the connecting hole to allow the bed mounting pin shaft 3-5 to pass through, thereby fixing the bed mounting bracket 3-4 to the adapter 3-3.

[0081] The motor mounting cylinder 3-2 is cylindrical, and one end of the motor mounting cylinder 3-2 is provided with an annular mounting cylinder flange 3-2-1. The fourth motor 3-8 is flanged and connected to the mounting cylinder flange 3-2-1. The adapter seat 3-3 is provided with an adapter seat flange 3-3-1, and the output end of the fourth motor 3-8 is flanged and connected to the adapter seat flange 3-3-1. The adapter seat sleeve 3-3-3 is provided on the side of the adapter seat 3-3 corresponding to the adapter seat flange 3-3-1. The adapter seat sleeve 3-3-3 is sleeved on the outside of the motor mounting cylinder 3-2 to increase the concentricity and support strength of the adapter seat 3-3 when rotating, thereby increasing the stability of the operating table position changes and ensuring stable support after the bed assembly is flipped into place.

[0082] In this embodiment, all motors are integrated servo torque motors with reduction drive. These motors have excellent performance under dynamic load and inertia conditions, can start at zero speed under full load, and have no shaking or vibration during start-up and stop. They also have high positioning accuracy, which can ensure the precise start-up and stop of the operating table at the predetermined position.

[0083] See Figure 1 and Figure 14 The bed assembly includes a second bed 200, which includes two symmetrically arranged second bed connecting parts 201 and two symmetrically arranged bed support beams.

[0084] The second bed connecting part 201 is disposed at the end of the bed support beam for connection and fixation with the bed tilting assembly 3.

[0085] The bed support beams include a first support beam 202 and a second support beam 203, which are hinged together. In this embodiment, a pin and nut assembly is provided at the hinge joint of the first support beam 202 and the second support beam 203. Loosening the pin and nut assembly allows the first support beam 202 and the second support beam 203 to rotate relative to each other, while tightening the pin and nut assembly fixes the relative position of the first support beam 202 and the second support beam 203, thereby reducing bed shaking during surgery and increasing the stability of the bed assembly.

[0086] A support component is provided between the two bed support beams for supporting and fixing the patient. In this embodiment, the support component may take the following form: a support bed board (not shown in the figure) is connected and fixed between the two first support beams 202, and a support bed board is also connected and fixed between the two second support beams 203. The two bed boards are used to support the patient's legs and torso, respectively.

[0087] The robotic arm adjustment components 2 of the two bed adjustment mechanisms control the two bed tilting components 3 to move closer together, so that the first support beam 202 and the second support beam 203 are in a "Λ" shape, which is used to perform surgeries such as spinal surgery (neurosurgery) that require special body positions on patients.

[0088] See Figure 1 and Figure 14 The bed assembly in this embodiment also includes a first bed 100, which is generally flat. When the patient uses the traction frame assembly 600 for traction treatment, he / she can lie on the first bed 100 for traction treatment.

[0089] See Figures 4 to 8 The bed adjustment mechanism further includes a caster assembly 5. The caster assembly 5 includes a caster beam 5-1 mounted on the base 4-1, two caster mounting seats 5-2 symmetrically arranged at both ends of the caster beam 5-1, and two casters 5-4 mounted on the two caster mounting seats 5-2. The two casters 5-4 are symmetrically arranged on both sides of the base 4. A brake adjustment shaft 5-3 passes through the caster beam 5-1 and the two caster mounting seats 5-2. The brake adjustment shaft 5-3 is rotatably mounted within the caster beam 5-1 and is made of hexagonal steel. A push rod mounting seat 4-2-1 is provided on the base plate 4-0. A brake electric push rod 4-2 is hinged to the push rod mounting seat 4-2-1. An adapter rod 4-2-3 is provided at the output end of the brake electric push rod 4-2. The adapter rod 4-2-3 is connected to the brake adjustment shaft 5-3. A hexagonal hole is opened on the adapter rod 4-2-3 corresponding to the brake adjustment shaft 5-3. The brake adjustment shaft 5-3 passes through the hexagonal hole. The output end of the brake electric push rod 4-2 extends and retracts to drive the brake adjustment shaft 5-3 to rotate. In this embodiment, the caster 5-4 is a medical caster. One end of the brake adjustment shaft 5-3 passes into the caster 5-4. The rotation of the brake adjustment shaft 5-3 locks or unlocks the caster 5-4.

[0090] See Figure 2 , Figure 7 and Figure 8The connecting beam 500 includes a first connecting beam 501 and a second connecting beam 502. The second connecting beam 502 is generally tubular, with one end fixed between the base plate 4-0 and the base body 4-1 by a screw assembly, and the other end provided with a connecting fixing sleeve 503. One end of the first connecting beam 501 is fixed between the base plate 4-0 and the base body 4-1 by a screw assembly, and the other end passes through the connecting fixing sleeve 503 and is inserted into the second connecting beam 502. The first connecting beam 501 slides relative to the second connecting beam 502 to adjust the distance between the two bed adjustment mechanisms. A bolt assembly is provided on the connecting fixing sleeve 503; tightening the bolt assembly fixes one end of the first connecting beam 501. Loosening the bolt assembly on the connecting fixing sleeve 503 allows the first connecting beam 501 and the second connecting beam 502 to be disassembled and separated, dividing the operating table into two, which facilitates the assembly and transportation of the bed adjustment mechanism.

[0091] See Figure 1 In this embodiment, a control panel 300 and a hand controller are provided on the support column 1 of any of the bed adjustment mechanisms for controlling the bed adjustment mechanism.

[0092] In this embodiment, the swing angles of the first robotic arm 2-1 and the second robotic arm 2-2 of the two sets of bed adjustment mechanisms are adjusted respectively, so that the bed assembly can complete the adjustment of lifting and lowering while maintaining a horizontal state; by changing the two robotic arm assemblies 2, one end of the horizontal bed assembly can be raised and the other end can be lowered; by changing the robotic arm assembly 2 on one side, the bed assembly can be raised and lowered on one side.

[0093] By adjusting the two bed tilting components 3, the bed components in a horizontal position can be rotated arbitrarily within a 360-degree range, and the bed components can also be tilted at a small angle to adapt to surgical needs. In addition, when adjusting the height of one or both ends of the bed components through the two robotic arm components 2, the two bed tilting components 3 can also tilt the bed components at a small angle.

[0094] See Figures 14 to 16 In the embodiment, a traction frame mounting base 1-5 is provided on one side of the support column 1 (a group without a control panel 300). A traction frame assembly 600 is detachably provided on the traction frame mounting base 1-5, which can be used in conjunction with the first bed 100 to perform traction treatment on the user.

[0095] Specifically, a T-shaped groove is vertically provided on the traction frame mounting base 1-5. A traction frame support plate 601 is provided at the bottom of the traction frame assembly 600. A traction frame mounting plate 603 is provided on one side of the traction frame support plate 601. A support rib plate 602 is provided between the traction frame mounting plate 603 and the traction frame support plate 601. The traction frame mounting plate 603 is slidably disposed in the horizontal part of the groove, and the support rib plate 602 is slidably disposed in the vertical part of the groove, thereby achieving stable installation of the traction frame assembly 600. After the traction frame mounting plate 603 slides into place, the traction frame fixing bolts 1-6 provided on one side of the traction frame mounting base 1-5 are tightened to fix the traction frame mounting plate 603, thereby fixing the traction frame assembly 600 on the support column 1 and increasing the functionality of the operating table.
