Abstract
Description
Technical Field
[0001] The present application relates to the technical field of medical auxiliary devices, and in particular to a radiation protection structure for an operating table. Background Art
[0002] Working in an interventional operating room will inevitably result in exposure to X-rays. According to the International Atomic Energy Agency (IAEA), scattered radiation is the main source of radiation for staff. Without proper protective measures, the amount of radiation received by doctors in the operating room may exceed the limit and have an impact on the body. Even small doses of radiation damage will gradually accumulate under long-term radiation exposure. During interventional surgery, the radiation received by patients comes from the radiation directly emitted by the X-ray machine. The radiation received by doctors, nurses and other operating room staff mainly comes from the radiation scattered by the patient's body.
[0003] X-rays have three effects when they enter the human body: 1. Pass through the human body 2. Be absorbed by the human body 3. Scatter (X-rays stimulate new rays). After the rays emitted by the tube enter the human body, 1% pass through the human body and enter the intensifier, the remaining 80% to 90% of the rays are absorbed by the patient, and 10% to 20% of the rays are scattered by the human body.
[0004] In order to reduce the impact of radiation on medical staff, protective equipment such as lead glass is installed between the operator and the tube to block the rays. At the same time, bedside curtains are also installed on both sides of the operating table to achieve good protection for medical staff.
[0005] However, the current protective equipment is usually arranged in advance by the surgeon according to the needs of the operation. The arrangement process requires adjusting the positions of the lead glass and the bedside curtains respectively until they are in the right position. After the shooting is completed, they are removed to avoid affecting the surgical operation. After the operation, the surgical effect needs to be observed, which increases the work pressure of medical staff and increases the operation time. Therefore, in order to solve the above problems, the present application provides a radiation protection structure for an operating table. Utility Model Content

[0022] The following is combined with Figure 1 - Figure 4 This application is described in further detail.
[0023] Embodiment 1:
[0024] Reference Figure 1 - Figure 4 A radiation protection structure for an operating table includes an operating bed 1, an X-ray machine 2 is arranged at one end of the operating bed 1, a linear module 5 with a movable position is arranged above the operating bed 1, two linear modules 5 are arranged corresponding to the two sides of the operating bed 1 respectively, the two linear modules 5 are movably connected with a hoisting mechanism 6, bedside curtains 4 are suspended below the two hoisting mechanisms 6, the two bedside curtains 4 are movably connected with a radiation protection structure 3, and the radiation protection structure 3 includes a lead glass 31 whose state is switched between horizontal and upright.
[0025] The top ends of the two bedside curtains 4 are fixedly connected to a cross bar 41, and the radiation protection structure 3 includes a bracket 32 welded between the two cross bars 41. The bracket 32 has a U-shaped structure when viewed from above, and the cross section of the bracket 32 is rotatably connected to the lead glass 31. Its two branch sections are rotatably connected to an electric telescopic rod 34 rotatably connected to the side wall of the lead glass 31. The electric telescopic rod 34 is extended and retracted to transmit the rotation of the lead glass 31 around its bottom end. When the electric telescopic rod 34 is at its shortest length, the lead glass 31 rotates to a nearly horizontal position. When the electric telescopic rod 34 is at its longest position, the lead glass 31 is arranged perpendicular to the surface of the operating bed 1.
[0026] Two guide rails 33 are welded below the bracket 32 parallel to the cross section, and the two guide rails 33 are slidably matched with the cross bar 41 of the bedside curtain 4. The width of the two bedside curtains 4 can be adjusted by using the cooperation of the guide rails 33 and the cross bar 41 to meet different needs. At the same time, the cross bar 41 can also synchronously carry the bracket 32 to move upward to achieve synchronous lifting of the cross bar 41 and the lead glass 31. The lifting mechanism 6 includes a support plate 64 below the linear module 5. The upper part of the support plate 64 is connected to the linear module 5 through a slider 65. Two steering rings 66 are welded below it. A motor 61 is provided at one end of the support plate 64, and The output end of the motor 61 is coaxially fixedly connected with a winding drum 63, and both ends of the cross bar 41 are fixedly connected with steel wire ropes 62, and the two steel wire ropes 62 are fixedly connected to the winding drum 63 through the steering ring 66. The motor 61 drives the winding drum 63 to rotate, and the winding drum 63 then reels the steel wire rope 62. When reeling, the cross bar 41 steadily moves upward and is finally reeled to a position close to the steering ring 66 and stops. When the motor 61 rotates in the reverse direction, the transmission winding drum 63 rotates in the reverse direction to unwind the steel wire, thereby realizing the delivery of the bedside curtain 4 to the positions on both sides of the operating bed 1, and protecting the position below the operating bed 1.
[0027] Threaded sleeves 7 are welded to both ends of the upper part of the two linear modules 5, and connecting rods are welded between the threaded sleeves 7. The connecting rods make the spacing between the two linear modules 5 fixed, and the two can be displaced synchronously. The inner threads of the two threaded sleeves 7 on the same side are connected with threaded rods 8, and the threaded rods 8 are arranged perpendicular to the linear modules 5. The threaded rods 8 rotate to drive the two linear modules 5 to displace synchronously along their axial directions, and finally the bedside curtains 4 and lead glass 31 hoisted above are transported to the top of the non-surgical bed 1 to avoid affecting the subsequent surgical process.
[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
