Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a retractable, universal interventional surgical platform based on the side rails of an operating table. Background Technology

[0002] Traditional interventional procedures are typically performed in a dedicated catheterization operating room / hybrid operating room. To facilitate intraoperative DSA imaging and accommodate interventional consumables such as guidewires and catheters, the catheterization operating table is generally ≥220cm long. This ensures sufficient space at the tail end to accommodate these consumables after the patient lies down. During interventional procedures, guidewires and catheters with long tails are prone to bending and kinking, affecting the surgeon's delivery. Therefore, sufficient length is also required for effective placement. A dedicated nurse is usually responsible for managing the guidewires and catheters to prevent bending and kinking.

[0003] Chinese patent CN119837642B discloses a universal interventional surgery platform and an automated radioactive particle implantation tool, belonging to the field of medical device technology. This universal interventional surgery platform includes a drive motor, a docking device, and a support bracket. The drive motor is fixed to the docking device, which is fixedly connected to the support bracket, which supports the surgical tool. The docking device has docking parts corresponding to the drive motors; one end of each docking part is connected to the drive motor via a transmission mechanism, and the other end is used to dock with the surgical tool, outputting power to it.

[0004] Currently, in traditional interventional surgeries, consumables are typically placed directly on the patient / operating table or delivered by a nurse, without standardized work surface products. Some interventional surgical robot and related consumable companies provide temporary / 3D-printed work surfaces to support the placement of consumables in multi-pathway interventional surgeries, while some may still require assistance from doctors / nurses to hold them.

[0005] The shortcomings of existing technology are: 1. Currently, there are no standard tabletop products for traditional interventional surgery / robotic interventional surgery; 2. Consumables used in multi-pathway interventional surgery require a greater standard table surface, so temporary tabletops are often used instead. Temporary tabletops are cumbersome to take out and put in, and are not easy to store.

[0006] Therefore, there is a need for a retractable universal interventional surgery platform based on the side rail of the operating table, which can solve the problems of insufficient space for consumables in traditional interventional surgery or the need for nurses to frequently tidy them up, and also meet the strict requirement of keeping guidewires and catheters horizontal and straight in interventional robotic surgery.

Detailed Implementation

[0023] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0024] like Figures 1 to 20 As shown, a retractable universal interventional surgical platform based on an operating table side rail provided by the present invention includes: an operating table 3 and a support frame 4. The support frame 4 includes: a side rail slider 41, a support rod 42, a rotating shaft 43, and a support plate 44. A transverse operating table side rail 21 is provided on the side of the operating table 2. The side rail slider 41 is installed on the operating table side rail 21 and the two form a sliding pair. The support frame 4 can move along the direction of the operating table side rail 21 through the side rail slider 41. The support rod 42 is vertically inserted into the side rail slider 41 and can move up and down. A locking device is provided on the support rod 42. The rotating shaft 43 is installed on the top of the support rod 42 and can rotate around the connection between the two. The support plate 44 is fastened to the rotating shaft 43. A guide rail 45 is fastened to the support plate 44. The operating table 3 is installed on the guide rail 45 and the two form a sliding pair. A locking device is provided on the operating table 3. The operating table 3 can switch between a horizontal state and a vertical state by rotating the rotating shaft 43.

[0025] In practical applications, operating table 2 has side rails 21 on both sides of the operating table 2. Two support frames 4 are installed on one side of the operating table side rail 21, and a side rail support seat 5 is installed on the other side of the operating table side rail 21. The position distribution of the two support frames 4 on one side of the operating table side rail 21 is mainly based on the width of the surgical robot trolley and is determined in combination with the overall weight and stress analysis of the operating table surface. The side rail support seat 5 serves as an auxiliary support (optional) to provide auxiliary support when the operating table surface 3 is pulled to its maximum stroke due to deformation caused by the overall weight. The main support position is near the rear end of the operating table 2.

[0026] The rotating shaft 43 includes a semi-circular part and a straight part. One end of the semi-circular part is connected to the straight part, and the other end is provided with a rotating shaft hole 431. It is connected to the support rod 42 by a butt bolt 432 to form a rotating pair. The rotating shaft 43 can rotate ≥270° around the support rod 42. The support plate 44 is fixedly installed on the straight part. Preferably, the support plate 44 is rigidly connected to the rotating shaft 43 by a countersunk bolt, and the guide rail 45 is rigidly connected to the support plate 44 by a cylindrical head bolt.

[0027] A limiting block 441 and a spring pin 442 are installed at the end of the support plate 44 away from the support rod 42. The limiting block 441 is used to prevent the operating table 3 from derailing when it is pulled out and to limit its maximum stroke. The operating table 3 is provided with a corresponding spring pin locking hole 34. After the operating table 3 moves to a suitable position, it is locked by the spring pin 442. A limiting groove is provided at the end of the support plate 44 near the support rod 42. When the operating table 3 is in a horizontal state, the support plate 44 is tightly engaged with the support rod 42 through the limiting groove. The support rod 42 is provided with a corresponding adjusting screw 421. The surface contact and limiting fixation between the support plate 44 and the support rod 42 serves as the main support. At the same time, the support plate 44 can effectively ensure the straightness of the guide rail 45 and reduce the deformation and tilting of the operating table 3. The upper part of the support rod 42 is provided with an adjusting screw 421, which is used to adjust the surface when the contact surface between the support plate 44 and the support rod 42 is worn, or when the operating table 3 is pulled to its maximum stroke and the operating table 3 is not level after contact. The lower part is also provided with an anti-disengagement bolt 424 to prevent the support rod 42 from disengaging from the side rail slider 41.

[0028] The upper part of the support rod 42 is provided with a positioning hole 422, and the lower part of the support rod 42 is provided with multiple equidistant circular holes 423, preferably seven circular holes, for adjusting the height of the operating table surface 3. Two locking caps 46 are installed on the support rod 42. The positioning hole 422 cooperates with the upper locking cap 46 to assist in supporting the rotating shaft 43, and the equidistant circular holes 423 cooperate with the lower locking cap 46 to adjust the height of the support rod 42, that is, to precisely position the height of the operating table surface 3. Inserting the locking pin 462 of the upper locking cap 46 into the positioning hole 422 on the upper part of the support rod 42 locks the rotating shaft 43, preventing it from rotating around the rotating shaft hole 431.

[0029] The lock cap 46 is fitted onto the support rod 42. A through hole matching the shape of the support rod 42 is formed in the center of the lock cap 46. The lock cap 46 includes a lock cap button 461 and a lock cap positioning pin 462. The lock cap positioning pin 462 is driven by the lock cap button 461 to insert into or move away from the support rod 42. Pressing the lock cap button 461 compresses the lock cap spring 4621 inside the lock cap 46, and releasing the lock cap button 461 releases the lock cap spring 4621, thus extending and retracting the lock cap positioning pin 462. The lock cap 46 has U-shaped grooves 463 at both ends of its main body. Set screws 464 ensure the overall structural integrity and functionality of the lock cap 46.

[0030] The side rail slider 41 has a through hole that matches the shape of the support rod 42, and the side rail slider 41 is located below the locking cap 46. The support rod 42 has an anti-loosening bolt 424 at its bottom, and the side rail slider 41 has a locking handle 411 that passes laterally through the side rail slider 41 and abuts against the support rod 42. The support rod 42 has a square cross-section, allowing it to be vertically inserted into the square hole in the middle of the side rail slider 41. The locking handle 411 is used to lock it to the operating table side rail 21. A single support frame 4 contains two locking caps 46, each with a square hole matching the cross-section of the support rod 42 for installation. Pressing the locking cap button 461 allows the locking cap 46 to move up and down along the support rod 42.

[0031] The back of the operating table surface 3 is equipped with multiple wear-resistant sliders 31 that match the guide rail 45, preferably three wear-resistant sliders 31 at each end. The wear-resistant sliders are made of high-molecular-weight polyethylene. The operating table surface 3 can move along the guide rail 45 via the wear-resistant sliders 31. The installation length of the wear-resistant sliders 31 has a certain margin compared to the total length of the guide rail 45, allowing for position adjustment of the operating table surface 3 within a certain range along the guide rail 45. The operating table surface 3 is equipped with a quick-release interface 33, providing an open interface that can adapt to different surgical procedures and different consumable installation requirements in interventional surgery. Furthermore, the surface of the operating table surface 3 has a hollow structure, mainly for the purpose of weight reduction and preventing structural deformation.

[0032] After the spring pin 442 locks the operating table surface 3, release the side rail slider 41 and turn the handle 411. Press the locking button 461 of the locking cap 46 and move it down a certain distance along the support rod 42. Fold the operating table surface 3 to 270° (vertical state) along the connecting bolt 432. Press the locking button 461 and slowly move it up to the highest point along the support rod 42, while simultaneously lowering the operating table surface 3 to the lowest position to complete the folding and storage state on one side.

[0033] The side rail support 5 is mainly used to assist in supporting the operating table surface 3, preventing deformation caused by excessive lever arm length when the operating table surface 3 is pulled out. The side rail support 5 includes: a support base 51, a connecting rod 52, a side rail support rod 53, and a side rail slider 41. The side rail support rod 53 is vertically mounted on the operating table side rail 21 via the side rail slider 41, and the two cooperate to form a sliding pair. The connecting rod 52 is mounted on the top of the side rail support rod 53, and the two cooperate to form a rotating pair. The top of the connecting rod 52 is fastened to the support base 51 with bolts and cannot be rotated. The support base 51 is used to support the operating table surface 3, and the lower part of the side rail support rod 53 is provided with anti-loosening bolts. Similar to the support frame 4, the side rail support 5 is mounted on the operating table side rail 21 via the side rail slider 41 and locked by turning the handle 411. The operating table side rail 21 is a common standard part with a uniform model and size in the market, so this application can be used to adapt to all operating tables 2. When the handle 411 is released, the side rail slider 41 can slide along the side rail 21 of the operating table to adjust the position of the entire operating table surface along the side rail 21 of the operating table. Similarly, the side rail support 5 can move up and down to adjust the height of the support 51.

[0034] The connecting rod 52 and the side rail support rod 53 are connected by bolts. The connecting rod 52 can rotate along the bolt axis. A locking button 54 is provided at the connection between the connecting rod 52 and the side rail support rod 53. The mating ends of the connecting rod 52 and the side rail support rod 53 are respectively provided with toothed mating surfaces. Pressing the locking button 54 will rotate the connecting rod 52 along the bolt axis. The mating ends of the side rail support 5 and the connecting rod 52 are respectively marked to indicate the two states of storage and support. When rotated to the support state, the support surface of the support 51 is horizontal. When rotated to the storage state, the support 51 rotates to the lowest position, and the side rail support 5 moves downward to adjust to the lowest position.

[0035] This application provides an independent surgical platform by using a support frame 4 as the connecting support structure for the operating table 3. It can effectively utilize the upper space from the patient's femoral artery to the foot for the placement of interventional consumables such as guidewires and catheters during the operation. This solves the problem of insufficient space for consumables in traditional interventional surgery or the need for nurses to frequently tidy them up. It also solves the problem of the rigid requirement for guidewires and catheters to be kept horizontal and straight in interventional robotic surgery.

[0036] This application solves the problem of non-foldable storage by using the rotation axis 43 of the support frame 4, which allows the operating table surface 3 to rotate around its rotation axis 270°, and by using the side rail slider 41 and the support rod 42 to adjust the height.

[0037] This application relies on the operating table side rail 21 for installation, and does not require frequent disassembly after installation, making it convenient for interventional surgery and easy to fold and store. The operating table 3 has a certain range of height and position adjustment, which can adapt to different sizes of operating tables 2 and patients of different body types. Some temporary tabletops for interventional surgery need to be customized according to the width of the operating table and the patient's body type. This application uses a combination of multiple sliding structures and a quick-release locking structure to achieve multi-directional adjustment on the three-dimensional frame of the operating table, solving the problem that temporary tabletops may be ill-fitting and affect the patient's legroom. In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", 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 application 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 application.

[0038] Specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the specific embodiments described above, and those skilled in the art can make various changes or modifications within the scope of the claims, which do not affect the essence of the present invention.
