Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and in particular to a surgical auxiliary table. Background Art

[0002] During surgical procedures, the surgical assist table serves as a platform for carrying instruments and consumables, and its performance directly affects surgical efficiency and safety.

[0003] Currently, some similar products still have technical limitations in clinical applications: First, the table tops mostly adopt an integrated structural design, and the size adjustment mechanism has limitations, making it difficult to achieve flexible adaptation. In large-scale surgical scenarios, insufficient load-bearing area can easily lead to instrument stacking and complicated access paths; in small-scale operations, fixed sizes may cause excessive space occupancy in the operating room, affecting medical and nursing route planning. Second, the storage module design is insufficient or missing, and spare instruments and consumables lack independent partitioned storage space and often need to be stacked together, which not only leads to disorder in the surgical operation area, but also makes it difficult to adapt to the aseptic management standards of the operating room. The above problems have restricted the smoothness of the surgical process to a certain extent, and there are potential clinical safety risks. Therefore, a surgical auxiliary table was designed. Summary of the Invention

[0004] In order to overcome the shortcomings of existing surgical auxiliary tables, such as non-adjustable table top size and insufficient mobile stability, the purpose of the present invention is to provide a surgical auxiliary table that can flexibly adjust the table top size according to the scale of the operation, while having good mobile stability and safety to meet the needs of modern surgical operations.

[0005] Technical solution: A surgical auxiliary table includes a storage tray, an expansion tray, a tripod, a mounting seat, a motor, a rotating rod and a folding rod. Through-type sliding grooves are opened on both sides of the storage tray along the length direction. The expansion tray forms a pull-out sliding fit with the storage tray through the sliding grooves. The bottom end of the storage tray is fixedly connected to the mounting seat by bolts. Two sets of tripods are symmetrically installed on the bottom end of the mounting seat. The driving motor is fixed to the center position of the top of the mounting seat through a flange. The output shaft of the motor is fixed to the rotating rod through a key connection. The two ends of the rotating rod are pivoted to the folding rod through a pin shaft. The end of the folding rod away from the rotating rod is pivoted to the bottom end of the expansion tray through a pin shaft to form a table telescopic drive assembly.

[0006] In addition, it is particularly preferred that the tripod includes a telescopic sub-rod, a telescopic mother rod and a positioning bead, the bottom end of the mounting seat is vertically fixed to the telescopic sub-rod, the telescopic sub-rod and the telescopic mother rod form a nested sliding fit, a number of positioning grooves are evenly distributed along the axial direction on the inner side wall of the telescopic mother rod, a mounting hole is radially penetrated by the lower end of the telescopic sub-rod, the positioning bead is connected to the hole by a spring, and the positioning bead forms a snap fit with the positioning groove to achieve height gear adjustment.

[0007] In addition, it is particularly preferred that a universal wheel is also included, and two sets of universal wheels with braking mechanisms are symmetrically fixed to the bottom end of the telescopic mother rod through bolts. The universal wheel adopts a foot-operated lever structure, which can realize instant locking and release of the wheel body.

[0008] In addition, it is particularly preferred that it also includes a convex strip, and the edge of the upper surface of the placement tray is fixed with a closed convex strip by an adhesive. The convex strip is made of medical-grade silicone material, has a semicircular arc structure in cross section, and is fixed to the surface of the placement tray by a food-grade adhesive.

[0009] In addition, it is particularly preferred that it also includes guide bars and guide rods. Two guide rods are symmetrically fixed to the bottom end of the expansion plate along the length direction, and the guide bars are fixed at corresponding positions on both sides of the mounting seat. A sliding groove adapted to the guide rod is opened on the inner side of the guide bar, and the guide rod and the guide bar form a sliding guide fit.

[0010] In addition, it is particularly preferred that it also includes a drawer and a handle, and horizontal pull-out grooves are symmetrically opened on both sides of the mounting seat. The drawers are slidably connected in the pull-out grooves through silent slide rails, and the handle is fixed to the middle of the outer surface of the drawer, and the handle remains flush with the drawer surface.

[0011] In addition, it is particularly preferred that the motor adopts a DC servo motor and is equipped with a forward and reverse controller, which can control the rotation angle through a pulse signal to achieve precise control of the extension and retraction stroke of the expansion disk.

[0012] In addition, it is particularly preferred that both the storage tray and the expansion tray are stamped from 304 stainless steel sheets, and the surface is electrolytically polished, making them corrosion-resistant and easy to clean.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1. This invention utilizes a DC servo motor to drive the rotating and folding levers, combined with the sliding grooves of the storage tray and expansion tray, to achieve electrically variable adjustment of the tabletop size. This flexible adjustment method allows precise adjustment of the tabletop size based on the instrument placement requirements of different surgical procedures. For large surgeries, the expansion tray can be fully extended to create ample storage space; for smaller surgeries, it can be retracted to reduce the space occupied by the tabletop, significantly improving space utilization and ensuring optimal use of operating room space.

[0015] 2. The present invention achieves convenient table height adjustment through the nested cooperation of the telescopic sub-rod and the telescopic mother rod, combined with the snap-fit ​​structure of the positioning beads and the multi-speed positioning groove. Different medical staff have different heights and operating habits, and different surgical scenarios also have different requirements for the height of the auxiliary table. This height adjustment structure allows medical staff to easily adjust the table height according to their needs, allowing them to maintain a comfortable posture during the operation and reduce fatigue. It can also better adapt to different surgical scenarios and improve the convenience of surgery.

[0016] 3. This invention utilizes medical silicone ridges on the edge of the tray, combined with universal wheels with brakes, to provide dual safety features. The ridges effectively prevent instruments from slipping, avoiding contamination or damage caused by dropped instruments. The universal wheels with brakes allow the auxiliary table to be flexibly moved when needed and securely fixed during surgical procedures, ensuring flexible switching between mobile and fixed positions, significantly enhancing operational safety and stability.

[0017] 4. This invention provides an ideal solution for storing surgical consumables through the drawer-style storage structure and silent slide rail design on both sides of the mounting base. The drawer-style structure enables orderly storage of surgical consumables, placing different types of consumables by category, making the surgical area more tidy and orderly, and reducing the interference caused by clutter. The silent slide rail design ensures that the drawers do not produce noise during operation, avoiding interference with the surgical process, improving convenience and safety, and complying with operating room aseptic management standards.

[0018] 5. This invention utilizes a 304 stainless steel countertop with an electrolytic polishing treatment, combined with the precise control of a DC servo motor, demonstrating significant advantages in multiple aspects. The 304 stainless steel countertop and electrolytic polishing treatment ensure the device's excellent resistance to disinfection and corrosion, as well as ease of cleaning and maintenance. This ensures the countertop remains clean over time, extending the device's service life. The precise control of the DC servo motor ensures smooth and precise positioning during the countertop expansion process, making countertop adjustment more precise and reliable, further enhancing the device's performance and user experience.

DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Embodiment: A surgical assisting table, such as Figures 1-8As shown, it includes a storage tray 1, an expansion tray 2, a tripod 3, a mounting seat 4, a motor 5, a rotating rod 6 and a folding rod 7. Through-type sliding grooves are provided on both sides of the storage tray 1 along the length direction. The expansion tray 2 forms a pull-out sliding fit with the storage tray 1 through the sliding grooves. This fit allows the expansion tray 2 to freely extend and retract along the length direction of the storage tray 1, thereby changing the length dimension of the entire table top. The bottom end of the storage tray 1 is fixedly connected to the mounting seat 4 by bolts. The bolt connection method not only ensures the firmness of the connection, but also facilitates installation and disassembly. Two sets of tripods 3 are symmetrically installed at the bottom end of the mounting seat 4. The symmetrically distributed tripods 3 can provide stable support for the entire auxiliary table, ensuring that it will not tip over during use. The driving motor 5 is fixedly installed at the center position of the top of the mounting seat 4 through a flange, which can ensure that the motor 5 runs smoothly during operation. The output shaft of the motor 5 is fixedly connected to the rotating rod 6 through a key connection. The key connection can reliably transmit torque, so that the rotating rod 6 rotates synchronously with the output shaft of the motor 5. The two ends of the rotating rod 6 are pivotally connected to the folding rod 7 through a pin shaft. The end of the folding rod 7 away from the rotating rod 6 is pivotally connected to the bottom end of the expansion plate 2 through a pin shaft to form a table telescopic drive assembly. When the motor 5 is working, the expansion plate 2 is driven to achieve telescopic action through the transmission action of this assembly.

[0030] like Figure 8 As shown, the bottom end of the mounting seat 4 is vertically fixed to the telescopic sub-rod 301, and the telescopic sub-rod 301 forms a nested sliding fit with the telescopic mother rod 302. A positioning groove is provided on the inner wall of the telescopic mother rod 302 at intervals along the axial direction. A mounting hole is radially penetrated by a mounting hole, and a positioning bead 304 is connected to the hole by a spring. The positioning bead 304 forms a snap fit with the positioning groove to realize height adjustment. During operation, it is easy to adjust by only pressing the positioning bead 304, which is suitable for the operating habits of medical staff of different heights and the height of the operating bed, thereby improving the flexibility of use.

[0031] like Figure 8 As shown, two sets of universal wheels 303 with braking mechanisms are symmetrically fixed to the bottom end of the telescopic mother rod 302 by bolts, which not only facilitates the flexible movement of the surgical auxiliary table to meet the usage requirements of different positions during surgery, but also can instantly lock the wheel body through foot braking to ensure that the equipment is stable and does not move during surgical operations, taking into account both mobility convenience and fixation reliability.

[0032] like Figure 6 As shown, a closed ridge 101 is provided on the edge of the upper surface of the storage tray 1. The ridge 101 is made of medical-grade silicone material and has a semicircular arc structure in cross section. It is fixed to the surface of the storage tray 1 by food-grade silicone rubber adhesive, preventing surgical instruments, medicines and other items placed on the storage tray 1 from sliding toward the edge, avoiding slipping due to collisions or slight vibrations, reducing the risk of contamination and damage, and at the same time, the silicone material meets the hygiene requirements of the medical environment.

[0033] like Figure 5 and Figure 7As shown, the guide rod 8 at the bottom end of the expansion disc 2 is in sliding guide cooperation with the sliding groove of the guide strip 401 on both sides of the mounting seat 4. During the expansion and contraction of the expansion disc 2 along with the folding rod 7, the guide rod 8 will slide along the sliding groove of the guide strip 401 synchronously. This guide cooperation structure can limit the movement direction of the expansion disc 2, prevent the expansion disc 2 from deviating or shaking horizontally during the expansion and contraction process, ensure the stability of the tabletop expansion or contraction, and thus improve the safety of the operation. Even in the case of complete expansion of the expansion disc 2, it can be stable and reliable, and will not appear skewed or shaking.

[0034] As shown, Figure 7 The drawer 9 connected by the silent sliding rail in the pull slot 402 on both sides of the mounting seat 4 and the handle 901 on the drawer 9 provide a special storage space for the spare instruments, dressings and other items needed during the operation process. The setting of the drawer 9 enables these items to be orderly stored, avoiding the clutter and pollution caused by piling on the ground. Medical staff can classify and place the items in different drawers 9 according to their types and purposes, for convenient access. The silent sliding rail design ensures that the drawer 9 will not produce noise during pulling, avoiding interference with the operation process, and also making the pulling action of the drawer 9 more smooth and labor-saving.

[0035] The motor 5 adopts a direct current servo motor equipped with a forward and reverse controller. The direct current servo motor has the advantages of high control precision, fast response speed and smooth running. Through the forward and reverse controller, the rotation direction and rotation angle of the motor 5 can be accurately controlled, and then the expansion and contraction stroke of the expansion disc 2 can be accurately controlled through the transmission mechanism. This precise control enables medical staff to adjust the tabletop to the most appropriate size according to the actual needs of the operation, ensuring enough space for placing instruments and not occupying too much operating room space. The motor 5 shell adopts a protective design, which can adapt to the humid environment of the operating room and prolong the service life of the motor.

[0036] The storage tray 1 and the expansion disc 2 are made of 304 stainless steel plate and the surface is treated by electrolytic polishing. 304 stainless steel has excellent corrosion resistance and can resist the erosion of various disinfectants during the operation. The electrolytic polished surface is smooth and easy to clean, meets the sterile management requirements of the operating room, and prolongs the service life of the equipment.

[0037] Tabletop expansion process: when the operation area needs to be expanded, the medical staff starts the direct current servo motor 5 at the top end of the mounting seat 4 through the foot switch. The output shaft of the motor 5 rotates clockwise, driving the rotating rod 6 to rotate synchronously through the key connection, and the folding rods 7 at both ends of the rotating rod 6 make circular motion. Since the folding rods 7 at both ends are respectively pivoted to the rotating rod 6 and the expansion disc 2, forming a double rocker mechanism, the included angle between the folding rod 7 and the rotating rod 6 increases from 30° to 150° during rotation, generating an outward pushing force to push the expansion disc 2 to expand outward along the sliding grooves on both sides of the storage tray 1 (the maximum expansion is 400 mm).

[0038] At this point, the guide rods 8 at the bottom of the expansion tray 2 slide synchronously along the guide bars 401 on both sides of the mounting base 4. The guide assembly limits the lateral deviation of the expansion tray 2, ensuring a smooth and shake-free extension and retraction process. When the tabletop needs to be retracted, the motor 5 rotates in the reverse direction, and the rotating rod 6 drives the folding rod 7 to reduce the angle, generating an inward pulling force, retracting the expansion tray 2 to its initial position. The entire adjustment process is quick and can be stopped at any position, achieving stepless adjustment.

[0039] Height adjustment process: Press the positioning bead 304 on the side wall of the telescopic mother rod 302. The positioning bead 304 compresses the internal coil spring and disengages from the current positioning slot, releasing the locking state between the telescopic sub-rod 301 and the telescopic mother rod 302. Now pull the mounting base 4 up or down, causing the telescopic sub-rod 301 to slide along the inner wall of the telescopic mother rod 302. When the desired height is reached, release the positioning bead 304. The coil spring returns to its original position and pushes the positioning bead 304 into the positioning slot at the corresponding height, thus fixing the length of the tripod 3 and completing the table height adjustment.

[0040] When pushing the auxiliary table, the foot brake on the universal wheel 303 is released, allowing the wheel to rotate freely, allowing the equipment to be flexibly moved. During surgery, the brake pedal is pressed, and the brake mechanism, through lever transmission, forces the brake pads to fit tightly against the wheel, generating friction that locks the wheel and ensures the stability of the equipment. The silicone ridges 101 on the edge of the storage tray 1 form a 15mm-high physical barrier. When instruments or consumables (such as syringes) are placed on the table, the ridges 101 prevent them from sliding toward the edge, preventing them from accidentally falling. Drawers 9 on both sides of the mounting base 4 can be easily extended and pulled out via silent slides. They are used to store surgical instrument kits (such as laparoscopic instrument boxes), sterile dressings (such as sterile gauze), and other spare items. The interior of the drawers 9 can be divided into 3-5 independent spaces (customizable in size) by partitions to meet classified storage needs.

[0041] The above is merely an example of the present invention and is not intended to limit the present invention. Any equivalent substitutions made within the principles of the present invention should be included within the scope of protection of the present invention. Any content not elaborated in detail in the present invention belongs to the prior art known to those skilled in the art.
