Description

Movable lead screen for radiation protection of round-the-island interventional diagnosis and treatment

Technical Field The present invention relates to an X-ray protective lead screen used for interventional surgery doctors, and in particular to a movable lead screen for radiation protection of round-the-island interventional diagnosis and treatment.

Background Art At present, interventional surgery has the characteristics of large exposure, long time, multi-angle projection, and close-to-table operation by surgeons. The X-ray radiation dose received by interventional doctors is several times to several times higher than that of other radiology department personnel. 10 times, although interventional physicians wear protective equipment such as lead clothing, long-term exposure to X-rays will cause certain damage to physical and mental health, so interventional protection needs to be further strengthened.

The most commonly used lead screens in clinical practice are as follows, as shown in Figure 1-3: The protective lead screen shown in Figure 1 is mainly suitable for protection applications during discontinuous exposure in radiation departments. Disadvantages: ①Because the height is too high, it blocks the surgeon's sight and intraoperative operation; ②A flat design cannot block rays from other directions. The protective lead screen shown in Figure 2 is mainly suitable for interventional surgery protection. Disadvantages: ①Because most of the material is metal "lead" and its own weight is high, the center of gravity shifts during multi-angle folding and use, and it is easy to fall to the ground; ②When the height is adjusted, the lead curtain also moves up, and the lower half ③In the design process, the base is too large, which takes up space, which is not conducive to the operator's operation; ④In the multi-angle folding use, it is easy to appear gaps, resulting in ray exposure; ⑤Complicated structure , There are many grooves, which is not conducive to cleaning, easy to breed bacteria, and increase the chance of infection. The protective lead screen shown in Figure 3 is a ceiling type lead screen, which is mainly suitable for interventional surgery protection. Disadvantages: ①The protection area is small, and it can only be used for radiation protection of the upper body of the first operator; ②Because it is suspended from the roof and supported by the arm, the range of motion is limited.

SUMMARY OF THE INVENTION The utility model discloses a movable lead screen for radiation protection of an island-type interventional diagnosis and treatment. During the interventional radiology operation, the lead screen can effectively form a complete radiation isolation protection area with a large protection range and reduce the radiation exposure of the surgeon. The bare area does not increase the operator's own weight, does not affect the flexibility of operation, and has reliable protection effects, making up for the deficiencies and vacancies of the current wearing method, hanging screen method and ordinary lead screen method. The utility model is applicable to all interventional operation X-ray protection requirements.

The technical scheme of the utility model is:

An island-type movable lead screen for interventional diagnosis and treatment radiation protection, including universal casters, stainless steel U-shaped lead plates, lead curtains, and radiation-proof glass plates. The stainless steel U-shaped lead plates are composed of five stainless steel lead plates in U-shaped symmetry The anti-radiation glass plate is made of two polymer resin glass plates. The anti-radiation glass plate is set on the upper end of the left part of the stainless steel U-shaped lead plate. The lead curtain is composed of lead curtains of equal size. Set at the lower end of the middle part of the stainless steel U-shaped lead plate, the universal wheel is arranged at the lower end of the stainless steel U-shaped lead plate, and the universal wheel is provided with a foot brake.

The stainless steel U-shaped lead plate is 85-90cm high and 215-220cm in circumference.

The height*width of the radiation-proof glass plate is 50*45cm and 50*25cm respectively.

The length*width of the lead curtain is 80*20cm.

The lead screen is also equipped with a disposable sterile instrument cover, which is made of disposable polyethylene transparent plastic film and sterilized by ethylene oxide.

The utility model has the advantages of novel design concept, stable center of gravity, free operation, clinical closeness, simple operation, high practicability, convenient cleaning and reliable protection effect of the lead screen.

In the figure 1. Stainless steel U-shaped lead plate; 2. Anti-radiation glass plate; 3. Lead curtain; 4. Universal casters.

Specific Embodiments After surgical patients are sterilized and spread sterile sheets, hospitals with conditions can seek manufacturers to customize disposable sterile instrument covers (refer to Figure 5) according to the equipment size in Figure 4. The material is disposable polyethylene transparent plastic film, which has been epoxy-treated Ethane sterilization, the validity period of sterilization is two years, the cost is low, and the patients can afford it easily. Surgeons use aseptic technique to cover all the disposable sterile instrument sets with the movable lead screen for radiation protection of the round-the-island interventional diagnosis and treatment; unconditional hospitals can use sterile sheet to cover all the movable lead screen for the radiation protection of the round-the-island interventional diagnosis and treatment, Then it will play the role of a sterile barrier, and the previously covered movable lead screen for radiation protection of round-the-island interventional diagnosis and treatment will be pushed to the operator's side of the imaging table, close to the edge of the bed, and both operators will be neatly dressed and stand on the stainless steel U-shaped 1 within the lead plate, the operation can be completed. The clinical operation is simple and practical, the radiation protection effect is significantly enhanced, it conforms to the aseptic technical operation specifications, and the incidence of intraoperative infection is reduced. The stainless steel U-shaped lead plate can effectively form a barrier to avoid ray radiation. Since the C-arm tube used in the operation is located on the side of the patient’s head, the operator stands under the right side of the patient, and the radiation-proof glass plate 2 is made of transparent polymer material, which is convenient for the operator to observe the patient’s condition, communicate with it, and quickly handle it; In the process of running up and down, the tube ball can play a barrier effect by means of the radiation-proof glass plate 2, so as to avoid ray radiation. When a person stands, speaking from the same plane, the toes protrude forward. During the operation, the operator needs to use the foot switch to control the exposure of the bulb. If it is a lead plate design, the operator's feet are easily injured, but the lead curtain 3 is soft and variable, which is more humane. The design of the lead curtain 3 can also be used as a test standard in clinical use for the upgrading of the utility model in the future, and a good bedding is done. The universal caster 4 makes the lead screen flexible, changeable and controllable during use; the wheel is provided with a foot brake, which can be fixed.
