Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a support frame assembly for orthopedic joint surgery. Background Technology

[0002] Orthopedics is a common department in hospitals. Bone or joint injuries and other bone diseases typically require diagnosis and treatment in orthopedics. Many serious orthopedic conditions cannot be completely cured with medication alone and require surgical intervention. During orthopedic surgery, positioning devices are used to stabilize the patient's arm or leg to facilitate the procedure.

[0003] Chinese Patent Application No. 2020203814479 discloses an adjustable support device for orthopedic clinical surgery. The device includes a base and an adjustment mechanism. A support cylinder is fixedly mounted on the top of a support plate. A horizontal plate is fixedly mounted on the support cylinder via the adjustment mechanism. A support rod is fixedly mounted on the top of a slider. A support frame for supporting the leg is fixedly mounted on the top of the support rod. A handle is rotatably connected to the side wall of the support cylinder near the bottom. A driving bevel gear is fixedly connected to one end of the handle inside the support cylinder. A lead screw is rotatably connected to the inner side wall of the support cylinder. A top rod is slidably connected to the top of the support cylinder. A driven bevel gear is fixedly mounted on the end of the lead screw outside the top rod. This utility model provides an adjustable support device for orthopedic clinical surgery.

[0004] The aforementioned approach has the advantage of being able to fix the patient's leg and allowing for height and angle adjustments, facilitating surgery. However, height adjustment alone is insufficient for surgical needs. Patients often need to bend their limbs during surgery to expose the corresponding joints, but existing orthopedic support devices mostly employ a horizontal structure design, which makes it difficult to provide sufficient and stable support for limbs in a bent position. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a support frame assembly for orthopedic joint surgery, comprising a base, a hook connected to one side of the base, a support column above the base, a support platform above the support column, support baffles on both sides of the support platform, a fixed bracket fixedly mounted on one side of the upper part of the support platform, a fixed plate connected to the fixed bracket, a rotating shaft on the other side of the upper part of the support platform, both ends of the rotating shaft connected to the support baffles, a flipping bracket rotatably mounted on the rotating shaft, a flipping plate connected to the flipping bracket, and a rotation drive component on the support platform that drives the flipping bracket to flip.

[0006] Preferably, the rotary drive component includes a worm gear, a worm, and a drive motor. The worm gear is rotatably mounted on a rotating shaft and connected to a tilting bracket. The bottom of the worm gear meshes with the worm. The drive motor is fixed to a support platform, and its output end is connected to the worm.

[0007] Preferably, the support column includes an inner column and an outer column sleeved on the inner column. The inner column has locking thread grooves arranged sequentially on its surface, and the outer column has locking bolts that pass through the side wall of the outer column and connect to the locking thread grooves.

[0008] Preferably, the base is provided with a rotary motor located below the support column, and the output end of the rotary motor is connected to the bottom of the inner column.

[0009] Preferably, the mounting bracket includes a side plate and an L-shaped hanging plate, the bottom of the side plate is connected to the base, the top of the side plate is connected to the L-shaped hanging plate, and the surface of the side plate is provided with a magnet.

[0010] Preferably, the base has a tool placement slot on the side of the support column.

[0011] The advantages of this utility model are:

[0012] 1. This solution combines a horizontal fixed plate with a flip-up plate, allowing doctors to flexibly adjust the angle of the flip-up plate relative to the fixed plate according to the specific surgical site and operational requirements. This ensures the patient's limb is in a suitable flexed position, fully exposing the corresponding joint position and facilitating surgical operations. It effectively solves the problem that existing equipment, which mostly uses a horizontal structure design, cannot meet the limb flexion support requirements.

[0013] 2. In this design, a worm gear drives a worm wheel to rotate, which in turn rotates the tilting support. This allows for precise positioning of the patient's limb according to surgical needs, making it suitable for orthopedic surgeries in different locations and positions. Furthermore, the transmission relationship between the worm gear and worm wheel has a self-locking characteristic, ensuring that the tilting support maintains its angle even when the drive motor stops, preventing positional shifts caused by slippage during surgery and improving the stability of limb support and surgical safety.

[0014] 3. This design features an inner and outer support column, with the outer column fitted over the inner column. The inner column has multiple locking threaded grooves on its surface, and the outer column has locking bolts with penetrating structures on its sidewalls. This structure allows for graded adjustment of the support column height, enabling doctors to quickly adjust the support height according to the patient's height or surgical requirements, offering high adaptability.

[0015] 4. This solution uses a rotary motor to drive the inner column to rotate around its axis, allowing the support device to be adjusted in the horizontal direction, thus making it more flexible to adapt to different surgical positions and operational needs. It is particularly suitable for orthopedic surgical operations in complex or asymmetrical positions.

[0016] 5. This solution allows for quick snap-fitting or mounting to the operating table via an L-shaped hanging plate. The magnetic blocks on the side plate further enhance the adhesion to the edge of the operating table. This dual fixing method improves assembly stability and effectively prevents shaking or slippage during use. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Simultaneously, when an component is referred to as "fixed to" or "equipped on" another component, it can be directly on the other component or may have an intervening component present. When an component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present. When an component is referred to as "fixedly connected to" another component, it can be a common fixed connection method such as welding, bolting, or gluing. In short, those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] Example 1, as Figure 1-3 As shown, a support frame assembly for orthopedic joint surgery includes a base 1. A hook 2 is connected to one side of the base 1, allowing the entire support frame assembly to be hooked onto the side of the operating table. A support column 3 is provided above the base 1, and a support platform 4 is provided above the support column 3. Support baffles 5 are provided on both sides of the support platform 4. A fixing bracket 6 is fixedly provided on one side of the upper part of the support platform 4, and a fixing plate 7 is connected to the fixing bracket 6. The fixing plate 7 is horizontally positioned.

[0026] On the other side above the support platform 4, there is a rotating shaft 8. Both ends of the rotating shaft 8 are connected to the support baffle 5. A flipping bracket 9 is rotatably mounted on the rotating shaft 8, and a flipping plate 10 is connected to the flipping bracket 9. A rotation drive is provided on the support platform 4, which drives the flipping bracket 9 to flip, causing the flipping plate 10 to rotate relative to the fixed plate 7 at a certain angle. In orthopedic joint surgery, the surgeon can flexibly adjust the angle of the flipping plate 10 relative to the fixed plate 7 according to the specific surgical site and operational requirements, so that the patient's limb is in a suitable flexed state, fully exposing the corresponding joint position, facilitating surgical operation, and effectively solving the problem that existing equipment, which mostly uses a horizontal structure design, cannot meet the limb flexion support requirements. For example, during elbow or knee joint surgery, the limb flexion angle can be precisely adjusted, allowing the surgeon to more clearly observe and operate on the joint. Because different types of orthopedic joint surgery have different requirements for limb flexion angles and support methods, the adjustable angle of the flipping plate 10 in this support frame assembly allows it to adapt to various orthopedic joint surgical scenarios. Whether it is a simple joint debridement surgery or a complex joint replacement surgery, it can provide surgeons with a suitable limb support solution to meet diverse surgical needs.

[0027] Combination Figure 3The rotary drive component includes a worm gear 11, a worm 12, and a drive motor 13. The worm gear 11 is rotatably mounted on a rotating shaft 8 and connected to the tilting bracket 9. The bottom of the worm gear 11 is engaged with the worm 12. The drive motor 13 is fixed to the worktable, and its output end is connected to the worm 12. The worm 12 drives the worm gear 11 to rotate, thereby driving the tilting bracket 9 to achieve angle tilting. The structure has a large transmission ratio, and the tilting action is smooth and highly controllable, which can meet the precise adjustment requirements of limb bending angle in orthopedic surgery. The transmission structure between the worm 12 and the worm gear 11 has a self-locking function, which can keep the tilting bracket 9 in its original angle position after the motor stops running, effectively preventing the patient's limb from accidentally sliding due to external force or gravity, and improving the safety and reliability of intraoperative positioning.

[0028] Combination Figure 2 The support column 3 includes an inner column 14 and an outer column 15 sleeved on the inner column 14. The inner column 14 has locking threaded grooves 16 arranged vertically on its surface, and the outer column 15 has locking bolts 17 that pass through the side wall of the outer column 15 and connect to the locking threaded grooves 16. Through the sleeved structure of the inner column 14 and the outer column 15, the outer column 15 can be moved up and down as needed, thereby achieving overall height adjustment of the support device to accommodate different patient body shapes and surgical positions. By using the locking bolts 17 to engage with the locking threaded grooves 16 on the surface of the inner column 14, the inner column 14 can be firmly locked after adjustment, preventing slippage or loosening due to gravity or external forces, and ensuring stable support during surgery.

[0029] A rotary motor 18 is located below the support column 3 on the base 1, and the output end of the rotary motor 18 is connected to the bottom of the inner column 14. The rotary motor 18 drives the inner column 14 to rotate around its axis, allowing the support device to be adjusted horizontally, thus more flexibly adapting to different surgical positions and operational needs, especially suitable for orthopedic surgeries in complex or asymmetrical positions. In this embodiment, the rotary motor 18 is a servo motor. The servo motor driver precisely controls the motor's movement based on feedback signals such as position and speed, achieving precise angle locking. When a stop command is issued, the driver stops outputting the drive current, the electromagnetic force inside the motor disappears, and the output shaft gradually stops under the combined action of its own friction and load inertia. The internal mechanical structure of the motor, such as bearings, provides a certain frictional resistance, preventing the output shaft from rotating on its own. To improve the self-locking effect, an electromagnetic brake can be installed on the output shaft of the servo motor. The electromagnetic brake is a common self-locking device. When the motor is powered on, the electromagnetic brake releases, allowing the output shaft to rotate freely; when the motor is powered off, the electromagnetic brake activates, locking the output shaft through friction to prevent rotation. Electromagnetic brakes are a well-known technology in the field. Various models, such as the German Mair compact and EAS-HT, can be used on the servo motor in this embodiment. Their specific structure will not be described in detail in this embodiment.

[0030] The mounting bracket 2 includes a side plate 19 and an L-shaped hanging plate 20. The bottom of the side plate 19 is connected to the base 1, and the top of the side plate 19 is connected to the L-shaped hanging plate 20. The surface of the side plate 19 is provided with a magnet 21. The L-shaped hanging plate 20 can be quickly snapped or hung on the operating table. The magnet 21 on the side plate 19 can further enhance the adsorption force with the edge of the operating table. The dual fixing method improves the assembly stability and effectively prevents shaking or slippage during use.

[0031] The base 1 is located on the side of the support column 3 and has a tool placement slot 22, which makes it convenient for doctors or surgical assistants to place commonly used tools or temporarily unused instruments in a dedicated position during the operation, avoiding frequent searching or misplacement, and improving the efficiency and smoothness of operation during the operation.

[0032] Combination Figure 4 In use, the entire support assembly is first attached to the side of the operating table via the hook 2. Then, the support column 3 is rotated by the rotary motor 18, which rotates the fixing plate 7 and the tilting plate 10 horizontally to a suitable angle. The patient's arm is then placed on the tilting plate 10 and the fixing plate 7. The fixing plate 7 is equipped with a fixing strap for easy fixation of the arm. If the surgery is performed on the leg, the entire support assembly can also be attached to the foot of the operating table for support.
