Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical equipment technology, specifically an operating table. Background Technology
[0002] Currently, after surgery, patients are mostly transferred manually. This is convenient for lighter patients, but for heavier patients, it can be strenuous, pulling on the wound and causing secondary injury, especially to patients with injuries to vital areas such as the cervical and lumbar spine. Some hospitals have electric medical transfer carts, which require two transfers—from the operating table to the cart and then to the bed—each involving moving the patient, which can easily cause injury. Furthermore, the efficiency of these carts is relatively low, occasionally leading to waiting times.
[0003] Chinese utility model patent CN218529135U discloses a concealed operating table stretcher, including a support fabric and support rods. The support rods are set on both sides of the support fabric to form a stretcher. The support fabric can be placed on the operating table before surgery, and after surgery, the support rods are passed through the support fabric, and then the patient is transferred to the operating table like a stretcher. The mechanism is simple, but it still requires the patient to be moved twice, which may aggravate the wound. Utility Model Content

[0037] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0038] Example 1
[0039] like Figure 1 As shown, an operating table includes a tabletop 1, a column 2, and a transfer cart 3;
[0040] like Figure 2-3 As shown, the bottom sidewall of the platform 1 is provided with a keyway 11 and a pin hole 10; the top sidewall of the column 2 is provided with a positioning key 5 that mates with the keyway 11 and a pin 4 that mates with the pin hole 10.
[0041] The bottom of the platform 1 is provided with several shaft slots 8 and platform proximity switches 7 around its perimeter.
[0042] like Figure 4 As shown, several column proximity switches 6 are arranged around the lower part of the column 2;
[0043] like Figure 5-8 As shown, the transfer cart 3 is provided with a shaft 13 corresponding to the shaft slot 8 provided on the platform 1 and a locking assembly 14 corresponding to the pin hole 10; the transfer cart 3 is also provided with a limit sensing column 21 corresponding to the column proximity switch 6.
[0044] like Figure 2 and Figure 4 As shown, an operating table board is provided on the table surface 1, and the column 2 is fixed on the base 12.
[0045] like Figure 5 As shown, the transfer vehicle 3 includes a bottom frame 25, a top frame 26 and a push rod 27. The bottom frame 25 and the top frame 26 are connected by a support column 28, and the top frame 26 is connected to the push rod 27.
[0046] like Figure 8As shown, the top frame 26 includes two top side rods 29 and a top cross rod 30. The two top side rods 29 are fixedly connected by the top cross rod 30. The two ends of the push rod 27 are respectively connected to the ends of the same side of the two top side rods 29. Insert shafts 13 and locking components 14 are provided on the top side rods 29 at certain intervals.
[0047] The number of insertion slots 8 is four, respectively set at the four corners of the bottom end of the platform 1, and the number of platform proximity switches 7 is two, set diagonally. In addition, as needed, those skilled in the art can also set four platform proximity switches 7 at the four corners, and set one insertion slot 8 and one platform proximity switch 7 at each corner. In this way, although more platform proximity switches 7 are used, it can better sense the connection status between the platform 1 and the column 2 compared to setting two platform proximity switches diagonally. Correspondingly, on the top frame of the transfer vehicle, two insertion shafts 13 are set on one top side rod 29, and the four insertion shafts 13 correspond to the four insertion slots 8.
[0048] like Figure 6 As shown, the transfer vehicle 3 also includes a limiting plate 23, which is mounted on the bottom frame 25. A limiting post 21 is provided at the rear end of one side of the limiting plate 23, and a sensing post 22 is provided on the inner side. Figure 7 As shown, a limiting post 21 is provided at the rear end of the limiting plate 23 on the other side and a sensing strip 31 is provided on the inner side.
[0049] Four column proximity switches 6 are arranged around the perimeter of the column 2: one on the front, one on the back, and one on each side. Correspondingly, limiting posts 21 and sensing posts 22 are provided on the limiting plate 23. The limiting post 21 corresponds to the column proximity switch 6 on the front of the column when the transfer cart enters from the front, and to the column proximity switch 6 on the back when entering from the back. The sensing posts 22 and sensing strips 31 correspond to the two column proximity switches 6 on the sides of the column, respectively. When the transfer cart is pushed in from the front, both sides can sense the proximity switches, the front can sense the proximity switches, but the back cannot. Conversely, when the transfer cart is pushed in from the back, both sides can sense the proximity switches, the back can sense the proximity switches, but the front cannot. When the column proximity switches on both sides sense the sensing posts and sensing strips 31, it indicates that the transfer cart is facing the operating table. When the column proximity switches on the front or back sense the limiting posts, it indicates that the transfer cart is positioned correctly and docking can be achieved.
[0050] like Figure 9As shown, the locking assembly 14 includes a locking block 17, a locking sleeve 15, a telescopic rod 16, a spring 18, and a welded post 19. The locking block 17 has a through hole at its upper part, the telescopic rod 16 is inserted into the through hole, the spring 18 passes through the telescopic rod 16, the locking sleeve 15 is fitted onto one end of the telescopic rod 16 and can be compressed back within the through hole, and the welded post 19 fixes the other end of the telescopic rod 16 to the locking block 17. The welded post 19 and the locking block 17 are welded together. The front end of the telescopic post 16 is connected to the locking sleeve 15, and the spring 18 is connected in the middle, allowing the spring 18 to push the locking sleeve 15 out.
[0051] A guide groove 9 is provided below the pin hole 10.
[0052] In this utility model, the column 2 and the base 12 are connected and fixed. The top of the column 2 has two pins 4 and four positioning keys 5 arranged symmetrically in the center. The bottom of the column 2 has four column proximity switches 6 distributed symmetrically in the center.
[0053] The positioning key 5 of the column 2 is positioned by the keyway 11. After positioning, the pin 4 extends and is inserted into the pin hole 10 to lock, thus combining the table 1 and the column 2 into a complete operating table.
[0054] like Figure 8 As shown, four insert shafts 13 and two locking assemblies 14 are symmetrically arranged on the top frame 26 of the transfer vehicle.
[0055] like Figure 6 As shown, the bottom frame includes two bottom side rods and a bottom cross rod. One end of the bottom side rod is connected to the front swivel wheel, and the other end is connected to the rear swivel wheel. The bottom side rods are fixedly connected to each other by the bottom cross rod. The front swivel wheel is braked by a front wheel brake handle 24, and the two rear swivel wheels are braked by a rear wheel brake lever 20.
[0056] The working process of the operating table of this utility model using a transfer cart:
[0057] like Figure 10 As shown, the transfer vehicle 3 approaches the column 2. The front end of the limiting plate 23 is slanted, which serves as a guide. When the transfer vehicle 3 is pushed inward, the limiting plate 23 limits the column 2 to the center of the transfer vehicle.
[0058] like Figure 11 As shown, the transfer vehicle 3 is pushed to the limit post 21 and contact the column proximity switch 6 of the column 2. At the same time, the sensing post 22 on the side of the limit plate 23 of the transfer vehicle 3 is aligned with the column proximity switch 6 on the side of the column 2. The column 2 detects the signals from the front and side proximity switches and reports that the transfer vehicle 3 has arrived in place. At this time, the rear wheel brake lever 20 and the front wheel brake handle 24 can be pressed down to fix the position of the transfer vehicle 3.
[0059] like Figure 12As shown, column 2 begins to descend. During the descent, the locking sleeve 15 compresses the spring 18 under the pressure of the guide groove 9 and retracts into the locking block 17. Two platform proximity switches 7, symmetrically arranged at the center of platform 1, detect that the insertion shaft 13 of the transfer cart 3 is inserted into the insertion shaft groove 8, and provide feedback that platform 1 and transfer cart 3 are in place. At this time, the locking sleeve 15 is concentric with the pin 4, the pin 4 retracts, and the spring 18 pushes out the locking sleeve 15 and locks it into the pin hole 10 of platform 1, thus completing the transfer of platform 1 from column 2 to transfer cart 3.
[0060] like Figure 6 , 13 As shown, column 2 continues to descend, and transfer vehicle 3 raises rear wheel brake lever 20 and front wheel brake handle 24, allowing transfer vehicle 3 to move platform 1 to the desired position.
[0061] like Figure 6 , 14 As shown, after the transfer vehicle 3 is moved into position, pressing the rear wheel brake lever 20 and the front wheel brake lever 24 will lock the transfer vehicle in place.
[0062] like Figure 15 As shown, the transfer vehicle 3 can transfer the platform 1 from both the front and rear directions.
[0063] In addition to the manual operation of the operating table to achieve the aforementioned functions, this invention can also incorporate various electronic control components and / or remote control components, such as hydraulic components and control components for controlling the lifting and lowering of the column, and control components for controlling proximity switches. These various electronic control components and / or remote control components can all employ techniques known in the art to achieve the aforementioned functions.
[0064] For any content not described in detail in this utility model, conventional technical knowledge in the field can be used.
[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
