Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of interventional surgery protection, and in particular, to an interventional surgery radiation protection device. Background Art

[0002] In the modern medical field, interventional surgery is an important diagnostic and treatment method, widely used in multiple disciplines such as cardiovascular, neurological, and tumors. Interventional surgery needs to be performed under the guidance of radioactive equipment such as X-rays to observe the position of surgical instruments and lesions in real time, which inevitably exposes doctors and related medical staff involved in the surgery to radiation environments.

[0003] Long-term exposure to radiation environment will cause many potential hazards to human health. In order to reduce the radiation hazards, it is currently common for doctors to wear lead suits, which can effectively block most of the rays and provide a certain degree of protection for medical staff. However, the lead suit is heavy, generally around 10 to 15 kilograms. In order to ensure the flexibility of the doctor's arms, the lead suit is generally designed in the form of short sleeves, and the length will not exceed the elbow. If the lead suit is designed to be long to the wrist, the doctor's arm will bear extra weight during the operation, making it difficult to ensure the accuracy and quality of the operation. Therefore, the current radiation protection measures for the arms of medical staff are insufficient, which is likely to cause potential harm to the health of medical staff.

[0004] To sum up, how to solve the radiation protection problem while ensuring that the doctor's arms do not bear the heavy weight of the lead suit and ensuring flexibility has become a difficult problem that needs to be solved urgently in the field of radiation protection in interventional surgery. Summary of the invention

[0005] To overcome the above-mentioned defects, an embodiment of the present invention provides an interventional surgery radiation protection device, which solves the technical problem of the lack of radiation protection measures for the arms of medical staff during interventional surgery in the related art.

[0006] According to one aspect, at least one embodiment of the present invention provides an interventional surgery radiation protection device, comprising a shield body, a mounting ring and a protective sleeve, wherein the mounting ring is disposed on the shield body, one end of the protective sleeve is connected to the mounting ring, and the protective sleeve is used to accommodate the operator's arm to block harmful radiation.

[0007] For example, at least one embodiment of the present invention provides an interventional surgery radiation protection device, further comprising: The barrier body has a receiving hole, which is in a strip shape. The barrier body is also provided with a first corrugated compensation layer, which covers the receiving hole. The first corrugated compensation layer has a mounting hole, and the mounting ring is arranged in the mounting hole. With the help of the first corrugated compensation layer, the mounting ring can move in the horizontal direction in the receiving hole on the premise that the receiving hole is closed, so as to adjust the lateral position of the operator's arm.

[0008] For example, at least one embodiment of the present invention provides an interventional surgery radiation protection device, further comprising: An air pump is arranged on the barrier body, an air outlet of the air pump is connected with a hose, an end of the hose is fixed to the inner wall of the mounting ring, and the hose is used for blowing air to maintain air circulation in the protective sleeve.

[0009] For example, at least one embodiment of the present invention provides an interventional surgery radiation protection device, further comprising: The cuff of the protective sleeve is also provided with an elastic ring, and the elastic ring is used to be put on the wrist of the operator to ensure the sealing of the cuff of the protective sleeve.

[0010] For example, at least one embodiment of the present invention provides an interventional surgery radiation protection device, further comprising: A power module is provided on the barrier body, and the power module is electrically connected to the air pump for supplying power to the air pump.

[0011] For example, at least one embodiment of the present invention provides an interventional surgery radiation protection device, further comprising: The horizontal projection of the barrier body is an arc. A plurality of pull ropes are arranged on the inner wall of the barrier body. A hook is arranged at the lower end of the pull rope. The hook is used to connect with the hanging ring on the lead suit worn by the operator to share the weight of the lead suit.

[0012] For example, at least one embodiment of the present invention provides an interventional surgery radiation protection device, further comprising: The inner wall of the barrier body is slidably provided with a sliding seat that can be raised and lowered, the top end of the pull rope is connected to the sliding seat, and the sliding seat can drive the pull rope to move upward to tighten the hanging ring on the lead suit worn by the operator to share the weight of the lead suit. The inner wall of the barrier body is provided with a driving member for driving the sliding seat to slide.

[0013] For example, at least one embodiment of the present invention provides an interventional surgery radiation protection device, further comprising: The barrier body includes a base section, a main body section and a pitch section which are arranged in sequence from bottom to top. The main body section is lifted and slidably arranged on the base section. The protective sleeve is located on the main body section. The pitch section is rotatably connected to the top of the main body section and can be swung vertically to adjust the pitch angle. The pitch section has a visible transparent window.

[0014] For example, at least one embodiment of the present invention provides an interventional surgery radiation protection device, further comprising: The main body section and the bending section are rotationally connected via a damping hinge shaft, and a handle is provided on the outer wall of the bending section. The handle is used for being pulled by the arm inserted into the protective sleeve to adjust the pitch angle of the bending section.

[0015] For example, at least one embodiment of the present invention provides an interventional surgery radiation protection device, further comprising: A flexible second corrugated compensation layer is connected between the leaning section and the main body section, and the second corrugated compensation layer can block the gap between the leaning section and the main body section when the leaning section swings vertically.

[0016] The beneficial effects of the embodiments of the present invention are: In the present invention, when performing a surgical operation, the medical staff puts their arms through the protective sleeve. At this time, since the protective sleeve is connected to the mounting ring, and the mounting ring is fixed to the barrier body standing on the ground, most of the weight of the protective sleeve is borne by the barrier body, which greatly reduces the burden on the arms of the medical staff. At the same time, the flexible shielding material of the protective sleeve can effectively block radiation and provide radiation protection for the arms of the medical staff, so that the medical staff can obtain good radiation protection while ensuring the flexibility of the arms.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] In interventional surgery, to resolve the contradiction between radiation protection and flexibility of medical staff's arms, see Figure 1~Figure 5 , which shows an interventional surgery radiation protection device in one embodiment of the present invention, including a shield body 1, a mounting ring 2 and a protective sleeve 3. The shield body 1 is the basic support structure of the entire protection device, made of a lead-containing composite material, and blocks between the radiation equipment and the doctor. The mounting ring 2 is arranged on the shield body 1, and one end of the protective sleeve 3 is connected to the mounting ring 2, which facilitates the medical staff to extend their arms into the protective sleeve 3. The protective sleeve 3 is made of a lightweight and flexible material containing a radiation shield.

[0027] During the operation, the medical staff puts their arms through the protective sleeve 3. At this time, since the protective sleeve 3 is connected to the mounting ring 2, and the mounting ring 2 is fixed to the barrier body 1 standing on the ground, most of the weight of the protective sleeve 3 is borne by the barrier body 1, which greatly reduces the burden on the arms of the medical staff. At the same time, the flexible shielding material of the protective sleeve 3 can effectively block radiation and provide radiation protection for the arms of the medical staff, so that the medical staff can get good radiation protection while ensuring the flexibility of the arms.

[0028] In some examples, such as Figure 1 and Figure 2 As shown, in order to allow medical staff to more flexibly adjust the lateral position of their arms when using the radiation protection device, a receiving hole 4 and a first corrugated compensation layer 5 are additionally provided on the shield body 1 .

[0029] The receiving hole 4 opened on the barrier body 1 is in the shape of a strip, ensuring that the mounting ring 2 can move smoothly therein. The first corrugated compensation layer 5 covers the receiving hole 4 and is made of a material with flexibility and radiation shielding performance, such as lead-containing rubber. The first corrugated compensation can not only effectively block radiation, but also keep covering the receiving hole 4 as the mounting ring 2 moves, as it stretches and contracts, to prevent radiation leakage. A mounting hole 6 is pre-arranged on the first corrugated compensation layer 5, and the mounting ring 2 is arranged in the mounting hole 6 and combined with the first corrugated compensation layer 5. The mounting ring 2 can move horizontally in the receiving hole 4. When the medical staff's arm drives the mounting ring 2 to move, the mounting ring 2 will drive the corrugations of the corresponding part of the first corrugated compensation layer 5 to expand or contract, thereby realizing the adjustment of the lateral position of the arm, while ensuring that the receiving hole 4 is always in a closed state to prevent radiation leakage from this part.

[0030] In some examples, such as Figure 2 and Figure 3 As shown, during the interventional surgery, medical staff wear the protective sleeve 3 for a long time to perform the operation. The protective sleeve 3 is prone to feel stuffy due to the lack of air circulation, which affects the operation efficiency. To solve this problem, an air pump 21 is provided on the barrier body 1. The air outlet of the air pump 21 is connected to a hose 7. The end of the hose 7 is fixed to the inner wall of the mounting ring 2 to ensure that it will not fall off during use. When the air pump 21 is started, the airflow generated by the air pump 21 is used to transport air to the protective sleeve 3 through the hose 7, and the stuffy air inside is continuously replaced, thereby maintaining the circulation of air in the protective sleeve 3. The comfort of the medical staff's arms is improved, so that the medical staff can always maintain a good operating state during a long operation.

[0031] In some examples, such as Figure 1 As shown, the cuff of the protective sleeve 3 is provided with an elastic ring 8. When the medical staff puts the arm into the protective sleeve 3 and puts the elastic ring 8 at the cuff on the wrist, the elastic ring 8 will fit the contour of the wrist by virtue of its own elasticity. On the one hand, it blocks the radiation from leaking from the cuff, and on the other hand, it prevents external air from entering the protective sleeve 3 and affecting the air circulation effect maintained by the air pump 21. A power module 9 is provided on the barrier body 1, and the power module 9 is electrically connected to the air pump 21 through wires to provide a stable power supply for the air pump 21.

[0032] In some examples, such as Figure 2 As shown, during the actual interventional surgery, medical staff need to wear lead suits. The lead suits are heavy, generally around 10 to 15 kilograms. Wearing heavy lead suits for protection for a long time not only puts a heavy burden on the body, but also affects the accuracy of the surgical operation.

[0033] To this end, the barrier body 1 is designed to be arc-shaped to surround the medical staff and better fit the body contour of the medical staff. A plurality of slides 12 are arranged on the inner wall of the barrier body 1, and a pull rope 10 is connected to the slide 12. A hook 11 is arranged at the end of the pull rope 10. A hanging ring or other structure that can be connected to the hook 11 can be arranged at the shoulder, waist and other parts of the lead suit. After the hook 11 is connected to the lead suit, the tightness of the pull rope 10 can be adjusted by sliding the slide 12 to ensure that the weight of the lead suit can be effectively shared. Two groups of slides 12 are symmetrically arranged along the central axis of the barrier body 1. The number of slides 12 in each group is preferably 2 to 4 groups, and they are arranged vertically. The height position of the slide 12 is adjusted by a driving member, which includes a screw rotatably arranged on the inner wall of the barrier body 1 and a knob at the end of the screw. The screw is threadedly matched with the screw hole on the slide 12. The pull rope 10 has a certain elasticity. When bearing the weight of the lead suit, the pull rope 10 can be stretched to a certain extent according to the slight movement of the medical staff's body, thereby reducing the pulling feeling felt by the medical staff during the surgical operation.

[0034] Before the interventional surgery, the medical staff first wears the lead suit and enters the arc-shaped barrier body 1, connects the hook 11 with the hanging rings on the shoulder and waist of the lead suit, and then drives the screw to rotate by rotating the knob, thereby adjusting the height position of the slide 12, so that the slide 12 drives the pull rope 10 to tighten the hanging ring, and part of the weight of the lead suit is transferred to the barrier body 1 through the pull rope 10. The barrier body 1 stands on the ground and can effectively share the weight of the lead suit.

[0035] In some examples, such as Figure 1 and Figure 2 As shown, during the interventional surgery, the doctor sometimes needs to bend over and get closer to the surgical area to perform more delicate operations, so the barrier body 1 is designed as a three-section structure.

[0036] Specifically, the bottom of the barrier body 1 is set as a basic section 13, and the main section 14 is lifted and slidably set on the basic section 13. The specific lifting method can adopt a conventional driving mechanism in the prior art, such as a motor driving a screw, a screw driving a nut, or a motor driving a gear, and a gear driving a rack.

[0037] The doctor can adjust the height of the main body section 14 according to his / her height, thereby changing the height of the entire barrier body 1, so that the visible transparent window 16 is always in the best position of the doctor's field of vision, which is convenient for the doctor to observe the surgical area. The main body section 14 is located above the base section 13, the protective sleeve 3 is located on the main body section 14, and the protruding section 15 is rotatably connected to the top of the main body section 14. The visible transparent window 16 is set on the protruding section 15, and the window is made of lead glass.

[0038] When the doctor needs to bend over to get closer to the surgical area for delicate operations, the pitch angle of the bending section 15 can be adjusted by pulling the handle 17 disposed on the outer wall of the visible transparent window 16. The middle part of the bottom edge of the bending section 15 is rotatably connected to the top of the main section 14 by means of a damping hinge 20. The damping hinge 20 can provide resistance so that the bending section 15 can remain in this position after being adjusted to a suitable angle. The handle 17 is disposed on the outer wall of the bending section 15, so that the doctor can easily touch it by raising his arm that has been inserted into the protective sleeve 3. There is no need to pull out the hand and then adjust the angle of the bending section 15, thereby achieving the purpose of delicate operations close to the surgical area. A flexible second corrugated compensation layer 18 is connected between the bending section 15 and the main section 14. The second corrugated compensation layer 18 is made of lead-containing rubber. When the leaning section 15 swings away from the main section 14, the second corrugated compensation layer 18 will expand with the swinging of the leaning section 15 to fill the gap between the leaning section 15 and the main section 14, ensuring that the area always remains closed and effectively preventing radiation from passing through the gap.

[0039] In some examples, such as Figure 1 As shown, a plurality of universal wheels 19 are evenly distributed at the four corners of the bottom of the barrier body 1. The universal wheels 19 can rotate 360 ​​degrees freely, and the protective device can be moved to the best position according to the actual needs of the operation. The protective device with universal wheels 19 can better adapt to various complex operating room environments and facilitate the management and maintenance of the equipment.
