Background

In modern hospital construction, the radiology department is a department integrating examination, diagnosis and treatment, and many diseases in clinical departments are required to be clearly diagnosed or assisted in diagnosis through the examination of radiology department equipment. The radiology department equipment generally includes a common radiography machine, a computer radiography system, a direct digital radiography system, a computer tomography, nuclear magnetic resonance, a digital subtraction angiography system and the like.

With the development of transcatheter interventional procedures, particularly with the development of transcatheter mitral valve and tricuspid valve repair techniques in recent years, the need for combining ultrasonic diagnosis with X-ray diagnosis has increased, and an interventional operator, which is an ultrasound imaging operator, has become one of the major operators. In the development of interventional procedures, the radiation exposure is higher and the radiation dose is higher because the operator needs to hold the transesophageal ultrasound probe with one hand and the catheter connected to the ultrasound probe with the other hand, which is located relatively closer to the radiation source. In the prior art, a radiation protection screen is adopted between an operator and a radiation source to block rays, and an arm of the operator needs to pass through an operation window of the radiation protection screen to operate medical instruments such as an ultrasonic probe and the like in the process of using the radiation protection screen, so that the operation window limits the movable range of the arm. The position of medical instruments such as an ultrasonic probe and the like needs to be continuously adjusted in the operation process, so that the corresponding arm also needs to be continuously adjusted, however, the existing operation window cannot be adjusted, so that the movable range of the arm is limited, and the operation is not easy to develop.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Embodiment one:

As shown in fig. 1-2, the present invention provides a radiation protection device 10, which includes a main body 100, wherein an operation window 110 penetrating the main body 100 is provided on the main body 100, the main body 100 contains a radiation protection material, and an area of the operation window 110 is adjustable. The main body 100 has a certain thickness and has two opposite protection surfaces perpendicular to the ground, and the operation window 110 penetrating the main body 100 means that the operation window 110 penetrates the two protection surfaces of the main body 100, so that an arm of an operator or other instruments can be conveniently protruded or transferred through the operation window 110.

Specifically, the main body includes a first lever 101, a second lever 102, a third lever 103, a fourth lever 104, and a fixed window 800, the first lever 101 and the second lever 102 are disposed at intervals in a horizontal direction (i.e., X direction), and the third lever 103 and the fourth lever 104 are disposed at intervals in a vertical direction (i.e., Y direction). The fixed window 800 is fixedly provided between the third bar 103 and the fourth bar 104 near the second bar 102, and is made of a transparent radiation-proof material, and an operator can observe a scene located at the other side of the main body 100 through the fixed window 800. As shown in fig. 2, the edges 810 of the first lever 101, the third lever 103, the fourth lever 104, and the fixed window 800 constitute four edges of the initial operation window 110, and the initial size of the initial operation window 110 in the vertical direction is H, and the initial size in the horizontal direction is L, and then the initial area S of the initial operation window 110 is l×h. The operation window 110 is provided through the main body 100, and an operator's arm can pass through the operation window 110 to reach the other side of the main body 100 at one side of the main body 100. Thus, when the operator is located at one side of the main body 100, the medical instrument or device (e.g., an ultrasonic probe, etc.) located at the other side of the main body 100 can be operated through the operation window 110.

Since the area of the operation window 110 is too small, the operation range of the operator is limited, and when the area of the operation window 110 is too large, the shielding performance is lowered. Therefore, the size of the operation window 110 in the vertical direction in this embodiment is between 100mm and 700mm, preferably between 200mm and 500 mm; the size of the operating window 110 in the horizontal direction is between 50mm and 800mm, preferably between 200mm and 600 mm.

As shown in fig. 3 and 5, the main body 100 is further provided with a movable window 700, the movable window 700 includes two sides 710, two sides 720 and lead glass, the two sides 720 are arranged at intervals in the horizontal direction (i.e., the X direction), the two sides 710 are arranged at intervals in the vertical direction (i.e., the Y direction), the two sides 710 and the two sides 720 form a quadrangular frame, and the lead glass is arranged in the frame. The movable window 700 is movably disposed between the third bar 103 and the fourth bar 104 and is close to the fixed window 800, the movable window 700 can move back and forth along the third bar 103/fourth bar 104, the first bar 101, the third bar 103, the fourth bar 104 and the edge 710 of the movable window 700 far from the fixed window 800 form four edges of the adjustable operation window 110, the size of the adjustable operation window 110 in the vertical direction is H, the size in the horizontal direction is L1, and then the area S1 of the adjustable operation window 110 is L1H.

Specifically, as shown in fig. 4, a side of the third lever 103 facing the fourth lever 104 is provided with a slide groove 1031, and one side 720 of the movable window 700 can slide in the slide groove 1031. The fourth bar 104 has the same structure as the third bar 103, and a side of the fourth bar 104 facing the third bar 103 is also provided with a sliding groove 1031, and the other side 720 of the movable window 700 is slidable in the sliding groove 1031 of the fourth bar 104. It can be seen that the two sides 720 of the movable window 700 can move in the corresponding sliding grooves 1031, so as to drive the two sides 710 of the movable window 700 to move in the horizontal direction (i.e., the X direction). The fixed window 800 and the movable window 700 are spatially offset from each other, so that the fixed window 800 does not interfere with the movement of the movable window 700 when the movable window 700 moves along the chute 1031, and the movable window 700 and the fixed window 800 may overlap on the XY plane, so that the maximum value of L1 may be L. Therefore, by adjusting the position of the edge 720 of the movable window 700 in the chute 1031, the size of the operation window 110 can be adjusted, and the area S1 of the operation window 110 can be adjusted. In this embodiment, no adjustment of the operating window 110 in the vertical direction is involved, that is, H is unchanged, L1 is 0.1-1 times L, that is, 0.1 x L1 is 1*L, correspondingly 0.1 x S1 is 1*S; preferably, 0.2×l.ltoreq.l1.ltoreq.0.9×l, correspondingly 0.2×s.ltoreq.s1.ltoreq.0.9×s; more preferably, 0.5×l.ltoreq.l1.ltoreq.0.8×l, and correspondingly 0.5×s.ltoreq.s1.ltoreq.0.8×s.

As shown in fig. 6, in some embodiments, 2 fixing windows 800 are provided on the main body 100, and two fixing windows 800 are fixedly provided between the third lever 103 and the fourth lever 104 at both ends of the third lever 103, respectively, and edges 810 of the third lever 103, the fourth lever 104 and the two fixing windows 800 constitute four edges of the initial operation window 110. The size of L2 can be adjusted by adjusting the position of the edge 720 of the movable window 700 in the chute 1031, thereby adjusting the area S2 of the operation window 110. In this embodiment, no adjustment of the operation window 110 in the vertical direction is involved, that is, H is unchanged, L2 is 0.1-1 times L, that is, 0.1 x L is L2 is 1*L, and correspondingly 0.1 x S is S2 is 1*S; preferably, 0.2×l.ltoreq.l2.ltoreq.0.9×l, correspondingly 0.2×s.ltoreq.s2.ltoreq.0.9×s; more preferably, 0.5×l.ltoreq.l2.ltoreq.0.8×l, and correspondingly 0.5×s.ltoreq.s2.ltoreq.0.8×s.

As shown in fig. 10, in some embodiments, the body 100 has two movable windows 700. The third bar 103, the fourth bar 104 and the edges 810 of the two fixed windows 800 constitute four edges of the initial operation window 110, and the area of the operation window 110 can be adjusted by adjusting any one of the movable windows 700. Thus, in this embodiment, the operator can adjust the operating window 110 both left and right, which facilitates faster adjustment by the operator.

For a left or right handed operator, if the position of the operating window 110 is not convenient for his or her dominant hand, the movable window 700 may be adjusted so that the left or right handed operator may be facilitated to operate the medical instrument through the operating window. For example, the position of the operation window 110 may be adjusted to be biased to the left side of the main body 100, thereby facilitating the operation of the medical instrument through the operation window by a left-handed operator; adjusting the position of the operation window 110 to be biased to the right side of the main body 100, thereby facilitating the right-handed operator to operate the medical instrument through the operation window; the device can be quickly adjusted to a left-hand mode or a right-hand mode, and the area of an operation window can be reduced to reach the minimum area meeting the use requirement in the operation process so as to reduce the risk and injury of an operator caused by radiation.

As shown in fig. 1 and 9, when an arm of an operator passes through the operation window 110 of the radiation protection device 10 to operate medical equipment such as an ultrasonic probe, the baffle 130 and the protection member 120 are positioned between the radiation source and the operator, so that injuries of radiation rays to the trunk, limbs, head and neck of the operator and human tissues including organs, thyroid and eyes positioned therein can be effectively reduced. In addition, the operator can see the ultrasonic probe, the patient, etc. through the perspective part of the baffle 130, and the hand of the operator can extend out from the opening 122 of the guard 120 to control the ultrasonic probe, so that the radiation protection device 10 can prevent the radiation from radiating the trunk, the limbs, the head and neck of the operator and the human tissues including organs, thyroid and eyes, etc. located therein on the premise of not affecting the operation of the operator, which is beneficial to more comprehensively and effectively protecting the operator.

The main body 100 includes a frame having a substantially rectangular shape. The frame is formed by welding or screw locking of metal materials, wherein the metal materials can be stainless steel, aluminum and other metal materials, and the frame made of the metal materials is convenient for installing the baffle 130 and the guard 120, and can provide larger supporting force for the baffle 130 and the guard 120.

Specifically, in the present embodiment, the frame of the main body 100 is made of stainless steel by welding a square tube.

Further, the outer surface of the frame of the main body 100 may be coated with a soft material such as plastic, etc. to reduce injury to the operator in case of a false impact.

As shown in fig. 1, in some embodiments, the operation window 110 is disposed at the middle of the main body 100, the baffle 130 is disposed at a portion of the main body 100 other than the operation window 110, portions of the baffle 130 adjacent to the operation window 110 on both left and right sides of the operation window 110 and a portion above the operation window 110 may be disposed as a perspective portion through which an operator located at one side of the main body 100 facing away from the radiation source can observe a surgical target area located at the other side of the main body 100, so that the operator can observe an operation to the surgical target area, thereby enabling adjustment of a position of a handheld medical device or instrument (e.g., an ultrasonic probe, etc.) when necessary. With the above arrangement, the main body 100 having the shutter 130 can shield the whole body of the operator, and the operation window 110 is located in the arm movement range of the operator.

The baffle 130 may be transparent or partially transparent as a whole, and when the baffle 130 has a partially transparent portion, the transparent portion is made of a transparent material containing lead, and for ease of understanding, the transparent portion on the baffle 130 is taken as a transparent protection plate, and other portions of the baffle 130 are taken as non-transparent protection plates as examples. The barrier 130 has at least 1 transparent shielding plate disposed adjacent to the operation window 110. When the barrier 130 has 2 or more transparent shielding plates, at least 1 transparent shielding plate is disposed adjacent to the operation window 110. Since the arm of the operator needs to pass through the operation window 110 during the operation, the head of the operator must be positioned around the operation window 110 when the arm of the operator passes through the operation window 110, and at least one transparent shielding plate is disposed around the operation window 110 so that the operator can observe the operation target area. At least one transparent shielding plate is located at an upper portion of the main body 100 and is disposed adjacent to the operation window 110, i.e., a perspective portion is at least partially located at an upper portion of the main body 100 and is disposed adjacent to the operation window 110.

The lead equivalent of the lower part of the main body 100 is larger than that of the upper part of the main body 100, and since the radiation source is generally arranged near the lower part of the main body 100, the radiation intensity of the radiation source to the lower part of the main body 100 is larger than that of the radiation source to the upper part of the main body 100, so that the lead equivalent of the upper part of the main body 100 can be lower than that of the lower part of the main body 100, the cost can be reduced, the protective performance of the main body is not influenced, and the protective effect is not reduced. In addition, the height of the main body 100 should not be lower than the operator's height, the height of the main body 100 is generally set to 1.6m-3.0m, and if the lead equivalent of the lower portion of the main body 100 is less than or equal to the lead equivalent of the upper portion of the main body 100 on the premise that the main body 100 has the above height, the gravity center of the main body 100 is easily unstable, which is unfavorable for the stable placement of the main body 100, and if the lead equivalent of the lower portion of the main body 100 is greater than the lead equivalent of the upper portion of the main body 100, the gravity center of the main body 100 can be ensured to be stable, and the position of the main body 100 can be maintained to be stable. Wherein the lead equivalent of the upper part of the main body 100 or the transparent shielding plate is not less than 0.3mmPb, preferably 0.5mmPb to 7.0mmPb, more preferably 1.0mmPb to 5.0mmPb. In some embodiments, the lead equivalent of the body 100 increases gradually from the upper portion to the lower portion of the body 100, so that the center of gravity of the body 100 is stabilized at the lower portion of the body 100, further facilitating stable placement of the body 100.

The baffle 130 may have a single-layer structure or a multi-layer structure. The baffle 130, which is a high purity lead plate, is positioned at the lower portion of the main body 100, and may be made of 99.99% electrolytic lead. Since too low a lead equivalent may cause deterioration of the shielding performance, and too large a lead equivalent may cause excessive weight of the barrier 130, thereby causing excessive weight of the entire apparatus and inconvenient movement, in the present embodiment, the lead equivalent of the barrier 130 located at the lower portion of the main body 100 is not less than 0.3mmPb, preferably 0.5mmPb to 12.0mPb, more preferably 2.0mmPb to 6.0mmPb. When the baffle 130 has a multi-layer structure, the inner layer of the baffle 130 is a lead plate, and the outer layer can be made of metal plates such as stainless steel, aluminum and the like, so that the manufacturing cost can be properly reduced while the radiation blocking function is ensured.

In one embodiment, as shown in fig. 7-9, the guard 120 includes at least two sub-guards 121. The adjacent two sub-shields 121 have an overlapping portion where the opening 122 is provided.

In some embodiments, the sub-shields 121 are made of a flexible material, and two adjacent sub-shields are fixedly connected to each other corresponding to the top of the overlapping portion, two adjacent sub-shields are fixedly connected corresponding to the bottom of the overlapping portion, and two adjacent sub-shields are not fixedly connected corresponding to the middle of the overlapping portion. With the above arrangement, as shown in fig. 6 to 7, in a natural state, the overlapping portion does not expose the opening 122; after the arm of the operator is inserted into the middle part of the overlapping part in a straight arm or a bent arm along the horizontal direction, the middle part of the overlapping part is extruded by the arm to form an opening 122, and the opening is in a working state at the moment; when the operator's arm is retracted, the overlapping portion loses force from the arm and returns to a natural state. Therefore, in a natural state, the overlapping portion is not exposed out of the opening 122, so that rays can be effectively blocked; in the operating state, since the opening 122 is provided in the middle of the overlapping portion, the upper and lower portions of the overlapping portion have no openings, so that the exposed area of the overlapping portion can be reduced, thereby reducing the risk of leakage of radiation.

In some embodiments, two adjacent sub-shields are fixedly connected to each other corresponding to the top of the overlapping portion, two adjacent sub-shields are fixedly connected to the bottom of the overlapping portion, two adjacent sub-shields are not fixedly connected to the middle of the overlapping portion, and the overlapping portion exposes the opening 122 in a natural state. Specifically, the side of the overlapping portion facing the operator does not expose the opening 122, and the side of the overlapping portion exposes the opening 122, thereby facilitating the passage of the arm of the operator through the guard 120, the operation window 110 in the horizontal direction via the opening 122.

It should be noted that the arm of the operator may pass through the sub-guard 121 through the opening 122 of the overlapping portion. It will be appreciated that the greater the number of sub-guards 121, the greater the number of openings 122 between the sub-guards 121, thereby enabling the guard 120 to reduce the restriction of the operator's arms. Thus, in other embodiments, the number of sub-guards 121 may also be three. The three sub-shields 121 are arranged laterally, and the sub-shield 121 located in the middle is at least partially overlapped with the sub-shields 121 on both sides, respectively. The opening 122 is formed in the overlapping portion for the arm of the operator to pass through.

It should be noted that, in the present invention, the length H4 of the guard 120 is not less than the dimension of the operation window 110 in the vertical direction, and the width W4 of the guard 120 is not less than the dimension of the operation window 110 in the horizontal direction. Therefore, the area of the shielding member 120 can be larger than the area of the operation window 110, so that the shielding member 120 can completely cover the operation window 110, and accidents caused by the fact that the shielding member 120 and the operation window 110 have gaps to radiate operators by the radiation source are avoided.

In general, the length H4 of the guard 120 should be at least 10mm greater than the dimension of the operating window 110 in the vertical direction; the width W4 of the guard 120 should be at least 5mm greater than the dimension of the operating window 110 in the horizontal direction. Preferably, the length L of the guard 120 exceeds the dimension of the operating window 110 in the vertical direction by a range between 20mm and 70 mm; the width W of the guard 120 exceeds the dimension of the operating window 110 in the horizontal direction by a range of between 10mm and 100 mm.

Further, the shielding member 120 is used for preventing radiation from being emitted to the operator through the operation window 110, and the opening 122 on the shielding member 120 allows the arm of the operator to pass through, so that the shielding member 120 has the function of shielding the radiation and at the same time, has flexibility. Specifically, in the present embodiment, the guard 120 is made of a flexible material containing lead, preferably lead rubber. In order to ensure a better protection effect of the protection member 120, the protection member 120 should have neat and beautiful appearance, clean surface, uniform color, and no defects such as specks and cracks. The lead equivalent of the guard 120 should be no less than 0.3mmPb, preferably 0.4mmPb to 4.0mmPb, more preferably 0.5mmPb to 2.0mmPb.

In one embodiment, the body 100 is further provided with a fixing member. The fixture is located above the operating window 110. The guard 120 is at least partially connected to the fixture. Accordingly, the guard 120 can be fixed above the operation window 110 by the fixing member. Under the influence of gravity, the rest of the guard 120 can cover the operation window 110 to shield the operation window 110.

Further, as shown in fig. 3 to 5, in one embodiment, the fixing member is a first hanging rod 140, the protection member 120 includes a hanging portion 123, and the protection member 120 is hung on the first hanging rod 140 through the hanging portion 123. The hanging portion 123 includes a first connecting portion 1231 and a second connecting portion 1232, a sliding portion 1233 is disposed between the first connecting portion 1231 and the second connecting portion 1232, and the first connecting portion 1231 is detachably connected with the second connecting portion 1232. When the first connecting portion 1231 is connected to the second connecting portion 1232, the sliding portion 1233 is bent to form a sliding channel, the axial direction of the sliding channel is parallel to the length direction of the first hanging rod 140, and the first hanging rod 140 is disposed in the sliding channel. The hanging portion 123 can drive the guard 120 to move laterally along the first hanging rod 140, and the body of the hanging portion 123 is made of flexible material, so as to facilitate bending and folding.

Specifically, in one embodiment, as shown in fig. 5, the first connection part 1231 is a female magic tape, and the second connection part 1232 is a male magic tape. When in use, the primary hook and loop fastener is adhered and combined with the primary hook and loop fastener around the first hanging rod 140, and a certain interval is arranged between the primary hook and loop fastener and the primary hook and loop fastener before the primary hook and loop fastener is adhered, and the interval forms a sliding part 1233 after the primary hook and loop fastener and the primary hook and loop fastener are adhered together. When the hanging portion 123 is hung on the first hanging rod 140, the sliding portion 1233 forms a curved sliding channel, and the first hanging rod 140 is disposed in the sliding channel. Thus, by this arrangement, the guard 120 can be made to move laterally along the first hanger bar 140.

In another embodiment, the first connecting portion 1231 is a sub-buckle, and the second connecting portion 1232 is a female buckle. The hanging portion 123 may be hung on the first hanging bar 140 by the snap-fit of the sub-buckle and the main buckle.

Further, in another embodiment, the first connection part 1231 is a first chain and the second connection part 1232 is a second chain. The second chain is provided with a zipper head, so that the first chain, the second chain and the zipper head form a zipper unit. The slider may connect or disconnect the first and second links. After the first chain is wound on the first hanger bar 140, the guard 120 may be hung on the first hanger bar 140 by controlling the slider so that the first chain and the second chain are connected.

In one embodiment, the hanging portion 123 is a hanger to hang directly on a hanger bar. In another embodiment, the hanging portion 123 is a magnetic patch, and the first hanging rod 140 is a magnetic rod. The first hanging rod 140 can be made of magnetic materials, and the first hanging rod 140 can be made to be magnetic through a mode of built-in magnets. Accordingly, the magnetic paste and the magnetic rod are combined under the magnetic force, so that the hanging part 123 is hung on the first hanging rod 140.

In one embodiment, as shown in fig. 1, the radiation protection device 10 further includes a stand 200, one end of the stand 200 is fixedly connected to the bottom of the main body 100, and a roller assembly is connected to the bottom side of the stand 200. The foot stand 200 can drive the main body 100 to move under the driving of the roller assembly, so as to facilitate moving the radiation protection device 10 to a proper position.

Further, the roller assembly includes a braking portion and a roller, and the braking portion can limit the rotation of the roller. Wherein, the main body 100 can be driven to move by the rotation of the roller. In a natural state, the braking part is not in contact with the roller, and at this time, the roller can be rotated randomly by an external force, so that the body 100 can be moved. In the braking state, the braking portion abuts against the roller to limit the rotation of the roller, thereby preventing the movement of the main body 100.

The braking portion may rotate relative to the stand 200: in a natural state, the roller assembly can be converted from the natural state to the braking state by pressing the pressing part downwards; in the braking state, the roller assembly can be converted from the braking state to the natural state by pulling up the braking part.

In one embodiment, as shown in FIG. 1, radiation protection device 10 further includes a hand rest support 300. The hand rest bracket 300 is positioned below the operation window 110 and fixedly connected with the main body 100. When in use, an operator can place the arm on the hand support bracket 300, so as to avoid fatigue and ache caused by long-time suspension of the arm, thereby being beneficial to providing a more comfortable operating environment for the operator and facilitating smooth operation.

Further, the hand rest 300 is provided with a concave region. The concave area is configured for an operator to place the arm. The hand rest 300 has a structure in which both sides are high and the middle is low to form the concave region, and both sides thereof are outwardly expanded in a direction away from the middle. Therefore, when the arm of the operator touches one side of the concave area, the arm can be placed in the concave area along the concave shape of the concave area without observing the position of the concave area, and the operator can blindly place the arm in the concave area, thereby being beneficial to improving the use efficiency. It will be appreciated that the recessed area 341 may be provided with soft padded silicone or an outer cloth lining to enhance operator comfort.

It should be noted that, when the adjustment range of the hand support 300 is too large, on one hand, the weight of the entire hand support 300 is increased to affect the firmness, and on the other hand, the adjustment difficulty is increased due to the overweight of the hand support 300, which is not beneficial to the operation; when the adjustment range of the hand support 300 is too small, the hand support 300 will limit the arm movement range of the operator, which is not beneficial to the operation. Thus, the hand rest support 300 has an adjustment range of 0-200mm in the vertical direction and 0-600mm in the horizontal direction, and preferably the hand rest plate 340 has an adjustment range of 0-100mm in the vertical direction and 0-400mm in the horizontal direction. The hand support bracket 300 is not too heavy on one hand in the adjustment section, so that the operation flexibility of the hand support bracket is ensured; on the other hand, the movable range of the arm of the operator is not limited.

In one embodiment, as shown in FIG. 1, radiation protection device 10 further comprises a hanger 400. The hanger 400 is rotatably coupled to the main body 100. When the hanging rack 400 is in a working state, an included angle between a hanging rod on the hanging rack 400 and the vertical direction is an acute angle or a right angle. It is understood that, in the working state, when a medical device such as an ultrasonic probe or a catheter is placed on the hanger 400, the medical device can be prevented from sliding off the hanger 400 and falling to the ground due to the gravity.

In one embodiment, as shown in FIG. 1, radiation protection device 10 further includes a suspension bracket 500. One end of the hanging bracket 500 is connected to the main body 100, and the other end of the hanging bracket 500 is used for hanging the display 600. Therefore, the display 600 can be connected to the main body 100 through the suspension bracket 500, so as to conveniently display the radiographic image of the operation area, so that an operator can comprehensively judge by combining the radiographic image and the ultrasonic image, which is beneficial to improving the judging efficiency and the judging accuracy, thereby further improving the quality of the operation.

Embodiment two:

The structure of the second embodiment is substantially the same as that of the first embodiment, except that the movable window 700 of the second embodiment can be moved in the vertical direction (i.e., the Y direction).

Specifically, as shown in fig. 11, the main body further includes a fifth bar 105 and a locking screw 1011, and a fixing window 800 is fixedly provided between the first bar 101 and the fifth bar 105 and near the first bar 101, which employs a see-through radiation-proof material, and an operator can observe a scene at the other side of the main body 100 through the fixing window 800. The first bar 101, the fifth bar 105, the fourth bar 104 and the edges 810 of the fixed window 800 constitute four edges of the initial operating window 110. The movable window 700 is movably disposed between the first rod 101 and the fifth rod 105 and is close to the fixed window 800, the movable window 700 can move back and forth along the first rod 101/the fifth rod 105, and the sides 710 of the first rod 101, the fifth rod 105, the fourth rod 104 and the movable window 700, which are far from the fixed window 800, form four sides of the adjustable operation window 110, and the size of the adjustable operation window 110 in the vertical direction is H1, and the size in the horizontal direction is L, so that the area S3 of the adjustable operation window 110 is l×h1. The first rod 101 is provided with a through hole (not shown in the figure), the locking screw 1011 can pass through the through hole and can collide with the edge 720 of the movable window 700, when the movable window 700 needs to be moved, the locking screw 1011 needs to be unscrewed, then the movable window 700 can be moved, after the movable window 700 is determined to reach the target position, the locking screw 1011 is screwed, at the moment, the edge 720 of the movable window is collided by the locking screw 1011, so that the movable window 700 cannot move, and therefore, the gravity can be overcome and the movable window 700 can be positioned at the target position.

The first lever 101 and the fifth lever 105 are identical to the third lever 103, and are each provided with a chute 1031 (not shown in the figure). Specifically, a side of the first lever 101 facing the fifth lever 105 is provided with a slide groove 1031, and one side 720 of the movable window 700 can slide in the slide groove 1031. The side of the fifth bar 105 facing the first bar 101 is also provided with a sliding groove 1031, and the other side 720 of the movable window 700 can slide in the sliding groove 1031 of the fifth bar 105. It can be seen that the two sides 720 of the movable window 700 can move in the corresponding sliding grooves 1031, so as to drive the two sides 710 of the movable window 700 to move in the vertical direction (i.e., the Y direction). The fixed window 800 and the movable window 700 are spatially offset from each other, so that the fixed window 800 does not interfere with the movement of the movable window 700 when the movable window 700 moves along the chute 1031, and the movable window 700 and the fixed window 800 may overlap on the XY plane, so that the maximum value of H1 may be H. Therefore, the size of H1 can be adjusted by adjusting the position of the edge 720 of the movable window 700 in the chute 1031, so that the area S1 of the operation window 110 can be adjusted. In this embodiment, no adjustment of the operating window 110 in the horizontal direction is involved, that is, L is unchanged, H1 is 0.1-1 times H, that is, 0.1 x H1 is 1*H, and correspondingly 0.1 x S1 is 1*S; preferably, 0.2×h.ltoreq.h1.ltoreq.0.9×h, correspondingly 0.2×s.ltoreq.s1.ltoreq.0.9×s; more preferably, 0.5×h.ltoreq.h1.ltoreq.0.8×h, and correspondingly 0.5×s.ltoreq.s1.ltoreq.0.8×s.

Through the arrangement, an operator can adjust the size of the operation window 110 in the vertical direction (Y direction), so that the area of the operation window 110 can be adjusted, and the medical instrument can be operated after the hand of the operator passes through the operation window 110. In addition, when the movable window 700 is located at a lower position, the operator standing operation or the operator operation with a higher height is facilitated by adjusting the movable window 700 to be raised in the vertical direction; when the movable window 700 is located at a higher position, the movable window 700 is adjusted to be lowered in the vertical direction, so that an operator can conveniently sit in a sitting position or operate by a shorter operator, and the risk and injury of the operator caused by radiation can be reduced due to the reduced area of the operation window, so that a better protection effect is achieved.

In some embodiments, as shown in fig. 12, the main body 100 further includes a sixth bar 106, and the sixth bar 106 has the same structure as the fifth bar 105, the movable window 700 is movably disposed between the sixth bar 106 and the fifth bar 105 and is close to the fixed window 800, the movable window 700 can move back and forth along the sixth bar 106/the fifth bar 105, and edges 710 of the sixth bar 106, the fifth bar 105, the fourth bar 104, and the movable window 700, which are far from the fixed window 800, constitute four edges of the adjustable operation window 110, and the area of the operation window 110 can be also adjusted by adjusting the position of the movable window 700. Similarly, the sixth rod 106 is also provided with a through hole, through which the locking screw 1011 can lock the movable window 700 or unlock the movable window 700.

Embodiment III:

The structure of the third embodiment is substantially the same as that of the first and second embodiments, except that the third embodiment has 2 movable windows 700, one of which 700 is movable in the horizontal direction and the other of which 700 is movable in the vertical direction. The two movable windows 700 are spatially offset from each other, so that one movable window 700 does not interfere with the movement of the other movable window 700 when it moves along the chute 1031, and 2 movable windows 700 may overlap on the XY plane, so that the maximum value of L3 may be L, H and the maximum value of H may be H. Therefore, by adjusting the position of the edge 720 of any one of the movable windows 700 in the chute 1031, the size of L3 or H2 can be adjusted, so that the area S4 of the operation window 110 can be adjusted. In this embodiment, L3 is 0.1-1 times L and H2 is 0.1-1 times H, i.e. 0.1 x l.ltoreq.l3.ltoreq. 1*L, 0.1 x h.ltoreq.h2.ltoreq. 1*H, and correspondingly 0.01 x s.ltoreq.s4.ltoreq. 1*S; preferably, 0.2×l.ltoreq.l3.ltoreq.0.9×l, 0.2×h.ltoreq.h2.ltoreq.0.9×h, and correspondingly 0.04×s.ltoreq.s4.ltoreq.0.81×s; more preferably, 0.5×l.ltoreq.l3.ltoreq.0.8×l,0.5×h.ltoreq.h2.ltoreq.0.8×h, and correspondingly 0.25×s.ltoreq.s4.ltoreq.0.64×s.

Through the arrangement, the operator can conveniently adjust the size of the operation window 110, the operator can adjust the size in the vertical direction, the size in the horizontal direction or both, and the operation is facilitated.
