[0042] This application provides a fixing device for a window field generator, which solves the problem of space occupation by the window field generator in the prior art. It enables the window field generator to be quickly and stably fixed under the operating table, eliminates safety hazards, and maximizes the utilization of the working range of the window field generator, thereby improving the precision of the surgery.
[0043] The technical solution in this application is to solve the above problems, and the overall approach is as follows:
[0044] Example:
[0045] like Figure 1-8 As shown, a fixing device for a window field generator includes: two main boards 1, two side components 2, and four suspension components 3; the two main boards 1 are arranged in parallel, and the two side components 2 are spaced apart between the two main boards 1, the two main boards 1 and the two side components 2 together form a frame structure; the four suspension components 3 are divided into two pairs and respectively arranged at both ends of the two main boards 1.
[0046] The side assembly 2 includes an upper protective cover 21 and a lower protective cover 22. The two ends of the upper protective cover 21 are fixedly connected to the main board 1, and the lower protective cover 22 is detachably connected to the upper protective cover 21. For example, one side is hinged and the other side is connected by screws, or both sides are connected by snaps. A cavity is provided between the upper protective cover 21 and the lower protective cover 22 for the tube of the window field generator 5 to pass through. The upper protective cover 21 and the lower protective cover 22 can effectively protect the tube of the window field generator 5 and prevent damage to the high-value window field due to misoperation.
[0047] The suspension assembly 3 includes a slider 31 and a hook 32. Several pads 33 are provided between the lower end of the hook 32 and the slider 31. The slider 31, pads 33 and hook 32 are respectively provided with mounting holes. The connecting bolts 34 pass through the hooks 32 and pads 33 in sequence to fasten the hooks 32 and slider 31. The number of pads 33 is adjusted according to the thickness of the operating table 6.
[0048] The lower part of the main board 1 is provided with a connection part that connects to the housing of the window field generator 5. The connection part is a groove corresponding to the housing of the window field generator 5, and a number of fixing studs 11 are provided in the groove. The fixing studs 11 correspond one-to-one with the fixing holes of the housing of the window field generator 5.
[0049] The main board 1 has a groove 12 on its upper part that matches the slider 31. The groove 12 extends horizontally through the main board 1. The sliders 31 of the two suspension components 3 on the same main board 1 are installed in the same groove 12. The hooks 32 of the two suspension components 3 on the same main board 1 are arranged opposite each other, that is, the upper ends of the hooks 32 extend inward for easy mounting on the operating table 6. A locking screw 35 is provided on the inward extension of the hook 32. The locking screw 35 passes through the upper end of the hook 32 to quickly lock the hook 32 to the operating table 6, thus firmly mounting the device on the operating table 6. A spring 4 is installed between the sliders 31 of the two suspension components 3 on the same main board 1. The two sliders 31 are tightened by the spring 4. The extension and retraction of the spring 4 can effectively control the range of use of the two sliders 31, achieving a rapid positioning effect and enabling installation in seconds. The overall structure of the slider 31 combined with the spring 4 allows the hook 32 of the fixing device to elastically extend and retract, adapting to operating tables 6 of different widths in clinical practice. Combined with the locking screw 35, it achieves quick locking and avoids damage to the device due to clinical misoperation.
[0050] Among them, the main board 1, slider 31, pad 33, hook 32, upper protective cover 21, and lower protective cover 22 are all made of plastic, while the remaining parts can be made of metal or plastic.
[0051] Furthermore, a stop 13 is provided between the sliders 31 of the two suspension components 3 on the same main board 1. The stop 13 is installed in the slide groove 12, or it can be integrally formed with the slide groove 12. In this case, the spring 4 is located above the stop 13. During the sliding process, when the opposite end faces of the sliders 31 approach each other, they can only hit the plastic stop 13, keeping a distance between the two sliders 31 and effectively preventing pinching.
[0052] Furthermore, a limiting groove 14 is provided at the bottom of the slide 12, and a limiting screw 15 is provided at the bottom of the slider 31. The limiting screw 15 passes through the limiting groove 14 and is connected to the slider 31. The limiting screw 15 slides within the limiting groove 14 to ensure that the slider 31 does not fall out of the main board 1 during the sliding process.
[0053] Optionally, one end of the slider 31 has a horizontal blind hole 311, and the side wall of the blind hole 311 has a mounting hole for a fixing screw 312. The fixing screw 312 passes vertically through the blind hole 311. The blind holes 311 of the sliders 31 of the two suspension components 3 on the same main board 1 are arranged opposite each other. The spring 4 has hooks at both ends, and the hooks at both ends of the spring 4 extend into the blind holes 311 of the corresponding sliders 31 and hook the fixing screws 312. This facilitates the installation and removal of the sliders 31 and the springs 4.
[0054] Optionally, the slide groove 12 is a dovetail groove, and the shape of the slider 31 corresponds to the slide groove 12. The dovetail groove structure allows the slider 31 to be installed quickly and is not easy to fall off. After the fixing device is installed and fixed on the operating table 6, the device can be pushed and pulled according to the patient's position and the working range of the device to facilitate the adjustment of the device position. During the movement, the limiting groove 14 and the limiting screw 15 limit the movement to prevent the slider 31 from falling off the main board 1.
[0055] The aforementioned window field generator's fixation device is used in electrophysiological surgery. Medical staff need to prepare the corresponding surgical instruments and equipment before the operation. The usage of the aforementioned window field generator's fixation device is as follows:
[0056] First, the window field generator is pre-installed on the fixed device. The two end housings of the window field generator are located in the connection part of the two main boards, and the two tubes of the window field generator are located in the cavity between the upper protective cover and the lower protective cover.
[0057] Next, place the fixing device with the hook facing up under the operating table, and then hang the hooks on one side of the two main boards on one side of the operating table. At this time, the fixing device is in a slightly tilted state.
[0058] Then, level the fixing device, and the hooks on the other side of the two main boards go around the other side of the operating table. Due to the spring force, the hooks on the other side will automatically attach to the other side of the operating table. When it is found that the patient's position is incorrect, there is no need to adjust the patient's position. Just gently pull the side to move the entire fixing device connected to the window field generator device back and forth and left and right.
[0059] Finally, once the current position is determined, quickly tighten the locking screws to press it firmly against the operating table, ensuring a secure connection. The installation of this fixation device is now complete.
[0060] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:
[0061] 1. This fixing device securely mounts the window field generator under the operating table using elastic telescopic hooks, making reasonable use of the space under the table and maximizing the working range of the window field generator, without occupying the space above the operating table, thus effectively reducing the burden on the surgical space; after being installed and fixed on the operating table, the device can be pushed and pulled to adjust its position according to the patient's position and the working range of the device.
[0062] 2. The installation of this fixation device is simple and can accommodate operating tables of different widths and thicknesses, meeting clinical needs, reducing the labor intensity of medical staff, and lowering surgical time and risks;
[0063] 3. The upper and lower protective covers of this fixing device can effectively protect the core and fragile parts of the window field generator and prevent damage.
[0064] 4. The components of this fixing device are easy and reliable to install and disassemble. If a single part is damaged, only the corresponding part needs to be replaced, thus reducing maintenance costs.
[0065] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
