Description

Technical Field

[0001] This invention relates to the field of operating table technology, specifically to an operating table used as an auxiliary tool in tumor resection. Background Technology

[0002] The operating table for tumor resection is a medical device specifically designed for tumor resection surgery. It aims to improve surgical efficiency, reduce the workload of doctors, provide patients with a more comfortable and safe surgical environment, and can be adjusted to various angles according to the doctor's needs.

[0003] When performing surgery on an operating table, the operating table needs to be disinfected. However, the existing disinfection methods are relatively simple. Generally, medical staff use handheld sprayers to spray disinfectant all over the operating table. This method not only fails to ensure that the disinfectant evenly covers every corner and surface of the operating table, resulting in incomplete disinfection in some areas and increasing the risk of infection, but also makes it impossible to precisely control the amount of disinfectant sprayed. Spraying too much or too little disinfectant will affect the disinfection effect. Furthermore, if the operation is improper or the equipment malfunctions, the disinfectant may splash onto the skin or eyes of medical staff or other personnel, creating a safety hazard.

[0004] Therefore, this invention proposes an operating table for tumor resection to solve the above problems. Summary of the Invention

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides an operating table for tumor resection, which has the following beneficial effects:

[0019] 1. The disinfectant spraying mechanism ensures that the disinfectant is evenly sprayed onto all surfaces of the operating table, achieving comprehensive and thorough disinfection without any blind spots. This kills bacteria, viruses, and other microorganisms on the operating table, effectively reducing the risk of infection during surgery. Furthermore, the automated spraying method simplifies the disinfection process, reducing the skill requirements and workload for medical staff. The even spraying also minimizes the need for repeated disinfection due to incomplete disinfection, improving the turnover efficiency of the operating room. It also prevents disinfectant from splashing onto the skin or eyes of medical staff or other personnel due to operational errors, reducing safety hazards caused by improper operation or equipment malfunction.

[0020] 2. The rotating shaft and fixed plate work together to precisely control the amount of disinfectant sprayed, avoiding the use of too much or too little disinfectant. This not only reduces the cost of medical institutions and the consumption of disinfectant, but also helps to reduce the pollution of the operating room environment caused by excessive disinfectant spraying, thus protecting the surgical environment. It also prevents the sprayed disinfectant from not reaching the upper surface of the bed, further improving the utilization rate of disinfectant.

[0021] 3. The limiting mechanism not only effectively prevents the position of the mobile frame from changing due to patient movement or anesthesia during surgery, ensuring accurate exposure of the surgical area and smooth operation, and reducing the risk to the patient during surgery, but also makes the bed layout neater and more orderly, facilitating operation for surgical personnel and reducing interference and delays caused by the sliding or adjustment of the mobile frame during surgery.

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] The operating table used in this embodiment for tumor resection is as follows: Figure 1 - Figure 8 As shown, the device includes a bed frame 1, with slide rails 2 fixedly connected to both sides of the bed frame 1. A movable frame 3 is slidably connected between the slide rails 2. A through groove 4 is provided on the movable frame 3, and a connecting groove 6 is provided on one side of the movable frame 3. The through groove 4 and the connecting groove 6 are connected. A spray pipe 5 passes through the movable frame 3. A nozzle 9 is fixedly connected to the lower end of the spray pipe 5. The spray pipe 5 and the nozzle 9 are connected. A liquid storage tank is fixedly connected to the upper end of the spray pipe 5. A disinfectant spraying mechanism 7 is provided between the spray pipe 5 and the movable frame 3. The disinfectant spraying mechanism 7 is used to evenly spray disinfectant onto various parts of the surface of the bed frame 1.

[0037] Preferably, the nozzle 9 is always perpendicular to the bed 1 to ensure that the disinfectant sprayed by the nozzle 9 comes into direct contact with the bed 1 with the shortest distance, thereby reducing the spread of the disinfectant.

[0038] Preferably, the movable frame 3 is telescopically mounted on the slide rail 2, so the movable frame 3 can be installed on beds of different widths, which facilitates the disinfection of beds of different widths.

[0039] In this embodiment, as Figure 3 As shown, the disinfectant spraying mechanism 7 includes a vertical plate 701, which is fixedly connected to the lower end face of the movable frame 3. A pulley 702 is symmetrically rotatably connected to the side of the vertical plate 701 away from the movable frame 3. A belt 703 is sleeved between the outer surfaces of the pulleys 702. A drive motor is fixedly connected to one of the pulleys 702. When the drive motor is turned on to drive one of the pulleys 702 to rotate, the belt 703 sleeved between the two pulleys 702 can drive the other pulley 702 to rotate synchronously, so that the belt 703 moves around the two pulleys 702.

[0040] In this embodiment, as Figure 3 - Figure 5 As shown, a fixing block 704 is fixedly connected to the outer surface of the belt 703. A telescopic plate 705 is rotatably connected to the side of the fixing block 704 away from the vertical plate 701. A connecting post 706 is fixedly connected to the upper end of the telescopic plate 705. A linkage block 707 is fixedly connected to the end of the connecting post 706 near the movable frame 3. The linkage block 707 is slidably connected in the communicating groove 6. A slider 708 is fixedly connected to the side of the linkage block 707 away from the connecting post 706. The slider 708 is fixedly connected to the outer surface of the spray pipe 5. The sliding connection is located in the through groove 4. When the belt 703 moves, the linkage block 707 can be driven to reciprocate in the through groove 6 through the fixed block 704, the telescopic plate 705 and the connecting column 706. This causes the slider 708 connected to the side wall of the linkage block 707 to reciprocate in the through groove 4. Since the slider 708 is fixedly connected to the outer surface of the spray pipe 5, when the slider 708 slides, it can drive the spray pipe 5 to move synchronously, thereby spraying the disinfectant evenly on all parts of the bed 1.

[0041] In this embodiment, as Figure 4 As shown, a ball valve 709 is fixedly connected to the spray pipe 5. A rotating shaft 710 is symmetrically connected to the outer surface of the ball valve 709. The rotating shaft 710 is used to control the opening and closing of the ball valve 709. When the rotating shaft 710 rotates, it can drive the baffle inside the ball valve 709 to rotate, thereby controlling the opening and closing of the ball valve 709.

[0042] In this embodiment, as Figure 4 and Figure 6As shown, the outer surface of the rotating shaft 710 is provided with a spiral groove 711. The upper end face of the movable frame 3 is symmetrically fixedly connected with a fixed plate 712. The fixed plate 712 is provided with a central hole 713. The rotating shaft 710 passes through the fixed plate 712 through the central hole 713. A limit bead 714 is fixedly connected to the inner wall of the central hole 713. The limit bead 714 is slidably connected in the spiral groove 711. When the rotating shaft 710 passes through the fixed plate 712 through the central hole 713, it is obstructed by the limit bead 714 and the spiral groove 711, and the rotating shaft 710 can rotate synchronously during horizontal movement.

[0043] In existing technologies, disinfection methods generally involve medical staff using handheld sprayers to spray disinfectant onto the operating table. This method not only fails to ensure even coverage of every corner and surface of the operating table, leading to incomplete disinfection in some areas and increasing the risk of infection, but also makes it difficult to precisely control the amount of disinfectant sprayed. Spraying too much or too little disinfectant will affect the disinfection effect. Furthermore, improper operation or equipment malfunction can cause disinfectant to splash onto the skin or eyes of medical staff or other personnel, creating a safety hazard. Compared to existing technologies, this method can evenly spray disinfectant onto all surfaces of the operating table, ensuring... The disinfectant solution can evenly cover every corner and surface of the operating table, achieving comprehensive and thorough disinfection of the bed, killing bacteria, viruses and other microorganisms on the operating table, thereby effectively reducing the risk of infection during surgery. Moreover, the automated spraying method simplifies the disinfection process, reduces the skill requirements and workload of medical staff, and the uniform spraying effect can also reduce the need for repeated disinfection due to incomplete disinfection, thereby improving the turnover efficiency of the operating room and avoiding the situation where disinfectant splashes onto the skin or eyes of medical staff or other personnel due to medical staff operation errors, reducing safety hazards caused by improper operation or equipment failure.

[0044] Secondly, the coordinated operation of the rotating shaft 710 and the fixed plate 712 allows for precise control of the amount of disinfectant sprayed, preventing the use of too much or too little disinfectant. This not only reduces the cost of medical institutions and lowers the consumption of disinfectant, but also helps to reduce the pollution of the operating room environment caused by excessive disinfectant spraying, thus protecting the surgical environment. Furthermore, it prevents the sprayed disinfectant from not reaching the upper surface of the bed 1, further improving the utilization rate of the disinfectant. Compared to manual spraying, it allows for more precise control of the spraying range, and the nozzle 9 is always perpendicular to the bed 1, ensuring maximum contact area of ​​the disinfectant with the bed 1. This avoids the disinfectant from failing to contact the bed 1 during tilted spraying and rapidly spreading into the air, resulting in insufficient disinfection of the bed 1, further improving the utilization rate of the disinfectant.

[0045] At other levels, this embodiment also provides a limiting mechanism 8 for fixing the position of the movable frame 3 on the bed 1, such as... Figure 2 and Figure 7 As shown, the limiting mechanism 8 includes a mounting plate 801, which is fixedly connected to one side of the bed body 1. Each mounting plate 801 is symmetrically slidably connected with a locking post 803, and each locking post 803 is connected with a locking plate 806. The locking plates 806 are fixedly connected to the side wall of the movable frame 3.

[0046] In this embodiment, as Figure 7 As shown, the mounting plate 801 has symmetrical grooves 804 on the side away from the bed body 1. Each groove 804 has a sliding dial 802, which is fixedly connected to the locking post 803. When the dial 802 is moved to slide in the groove 804, the locking post 803 can be driven to slide into the mounting plate 801.

[0047] In this embodiment, as Figure 7 As shown, springs 805 are fixedly connected to the side of the lever 802 away from the locking post 803. The end of the spring 805 away from the lever 802 is fixedly connected to the inner wall of the groove 804. When the lever 802 is pressed and slides in the groove 804, it will simultaneously squeeze the spring 805. After the force on the lever 802 disappears, the rebound force of the spring 805 will automatically push the lever 802 to slide to the initial position in the groove 804.

[0048] Compared with existing technologies, the ability to fix the mobile frame 3 to the bed 1 near the patient's feet after the disinfectant is sprayed not only effectively prevents the position of the mobile frame 3 from changing due to the patient's body movement or the effects of anesthesia during the operation, ensuring accurate exposure of the surgical area and smooth operation, and reducing the risk to the patient during the operation, but also makes the layout of the bed 1 neater and more orderly, which is convenient for the surgeons to operate and reduces the interference and delays caused by the sliding or adjustment of the mobile frame 3 during the operation.

[0049] The overall working process and principles involved in the above embodiments are as follows:

[0050] When medical staff need to spray disinfectant on bed 1, they first turn on the drive motor to rotate one of the pulleys 702 on the side wall of the vertical plate 701. One pulley 702, via a belt 703 fitted on its outer surface, drives the other pulley 702 to rotate synchronously. This causes the belt 703 fitted between the outer surfaces of the two pulleys 702 to move synchronously. During the movement of the belt 703, the belt 703 drives the fixed block 704 connected to its outer surface to move around the two pulleys 702, thus actuating the rotating components on the fixed block 704. The lower end of the telescopic plate 705 moves synchronously. Since a connecting post 706 is fixedly connected to the upper end of the telescopic plate 705, and a linkage block 707 is connected to the connecting post 706, when the fixed block 704 moves the lower end of the telescopic plate 705, the connecting post 706 on the telescopic plate 705 drives the linkage block 707 to slide back and forth within the connecting groove 6. Furthermore, as the fixed block 704 moves up and down with the belt 703, the telescopic plate 705 can extend and retract synchronously, allowing the fixed block 704 to actuate the linkage block 707 at any time. The movable block 707 slides within the connecting groove 6, and the linkage block 707 can drive the slider 708 to slide synchronously within the through groove 4 opened on the movable frame 3. Since the slider 708 is fixedly connected to the outer surface of the spray pipe 5, during the sliding process of the slider 708, it can drive the nozzle connected to the lower end of the spray pipe 5 to move synchronously and uniformly over the bed 1, thereby enabling the spray pipe 5 to evenly spray the disinfectant through the nozzle 9 connected to the lower end onto the upper surface of the bed 1, ensuring that the disinfectant can evenly cover every surface of the operating table, and achieving disinfection of the upper surface of the bed 1. Comprehensive disinfection kills bacteria, viruses and other microorganisms on the operating table, thereby effectively reducing the risk of infection during surgery. Moreover, the use of automated spraying can simplify the disinfection process, reduce the skill requirements and workload of medical staff, and the uniform spraying effect can also reduce the need for repeated disinfection due to incomplete disinfection, thereby improving the turnover efficiency of the operating room and avoiding the situation where disinfectant splashes onto the skin or eyes of medical staff or other personnel due to medical staff operation errors, reducing safety hazards caused by improper operation or equipment failure.

[0051] As the slider 708 moves the spray pipe 5, the spray pipe 5 moves the ball valve 709 horizontally in sync, causing the ball valve 709 to move away from one of the fixed plates 712 on the upper surface of the moving frame 3. At this time, one of the rotating shafts 710 connected to the ball valve 709 slides out of the fixed plate 712 through the central hole 713. Simultaneously, the rotating shaft 710 is affected by the spiral groove 711 on its outer surface and the limiting bead 714 installed on the inner wall of the central hole 713, causing the rotating shaft 710 to rotate 90 degrees synchronously as it slides out of the fixed plate 712, thereby opening the ball valve 709. Please refer to [reference needed] for details. Figure 8This allows the spray pipe 5 to deliver liquid to the nozzle 9 for spraying. When the slider 708 slides in the through groove 4, causing the spray pipe 5 and the ball valve 709 to move closer to another fixed plate 712, another rotating shaft 710 on the ball valve 709 will pass through the central hole 713 again through the fixed plate 712, causing the spiral groove 711 to contact the limiting bead 714. The spiral groove 711 is obstructed by the limiting bead 714, which will cause the rotating shaft 710 to rotate again, so that the spiral groove 711 adapts to the limiting bead 714, and the rotating shaft 710 passes through... When the fixed plate 712 is passed and the rotating shaft 710 rotates again, it will drive the ball valve 709 to close automatically. This can precisely control the amount of disinfectant sprayed, avoiding the use of too much or too little disinfectant. This not only reduces the cost of medical institutions and the consumption of disinfectant, but also helps to reduce the pollution of the operating room environment caused by excessive disinfectant spraying, thereby protecting the operating room environment. It can also prevent the sprayed disinfectant from not being sprayed on the upper surface of the bed 1, further improving the utilization rate of disinfectant.

[0052] After the nozzle 9 has reciprocated and evenly sprayed a portion of the surface of the bed 1, the medical staff can use the slide rails 2 on both sides of the bed 1 to move the movable frame 3 horizontally on the bed 1, so that the nozzle 9 can move to various locations above the bed 1. After the medical staff has disinfected the bed 1, they can control the movable frame 3 to slide along the slide rails 2 and move it to the foot area of ​​the bed 1. When the movable frame 3 is about to move to one side of the bed 1, the medical staff first pulls the two levers 802 on the mounting plate 801 to slide them closer to each other in the groove 804, compressing the spring 805 connected between the levers 802 and the groove 804, and causing the locking pins 803 connected to the levers 802 to slide into the mounting plate 801. After the movable frame 3 moves close to the mounting plate 801, Medical staff can then release the lever 802. Through the rebound force of the spring 805 connected between the lever 802 and the groove 804, the lever 802 can be pushed away from each other, causing the locking post 803 connected to the lever 802 to slide out from the mounting plate 801 again and be inserted into the locking plate 806 connected to the side wall of the moving frame 3. This not only effectively prevents the position of the moving frame 3 from changing due to the patient's body movement or the influence of anesthesia during the operation, ensuring accurate exposure of the surgical area and smooth operation of the operation, and reducing the risk to the patient during the operation, but also makes the layout of the bed 1 more neat and orderly, so as to facilitate the operation of the surgical staff and reduce the interference and delay caused by the sliding or adjustment of the moving frame 3 during the operation.
