Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical protective cover, and particularly relates to a radiation-proof three-dimensional protective cover for scanning and detecting cancerous regions. BACKGROUND

[0002] When detecting cancer, a protective cover is usually used to isolate the detection light from the external environment, that is, the scanning and detecting process is carried out in the protective cover. Therefore, in order to facilitate operation, the protective cover is usually a three-dimensional protective cover, which is placed on the patient to form an operation space between the three-dimensional protective cover and the patient.

[0003] However, the existing protective cover is usually attached to the skin of the patient, and if only the local position covered by the three-dimensional protective cover needs to be scanned and detected, the other positions in the three-dimensional protective cover usually lack protection. That is, although the protective cover can reduce the radiation from the outside, the patient himself lacks protection.

[0004] Therefore, in the scanning and detection of cancerous regions, the existing technology has the problem that the non-detection area in the three-dimensional protective cover lacks protection during detection. SUMMARY

[0005] In view of the problems in the prior art, the present application provides a radiation-proof three-dimensional protective cover for scanning and detecting cancerous regions, which has the advantage of protecting the non-detection area in the three-dimensional protective cover, and solves the problem that the non-detection area in the three-dimensional protective cover lacks protection in the prior art.

[0006] The present application is implemented as follows: a radiation-proof three-dimensional protective cover for scanning and detecting cancerous regions, comprising:

[0007] a base having a circular hole, a first protective plate rotatable on the base, the first protective plate completely covering the circular hole, the first protective plate having a first detection hole, and the first detection hole coinciding with the circular hole; a cover body, the lower edge of the cover body being rotatably attached to the base, and the cover body completely covering the first protective plate; and a detection head mounting frame connected inside the cover body for carrying a detection head.

[0008] Preferably, the cover body and the first protective plate are connected by a detachable connecting mechanism.

[0009] Preferably, the detachable connecting mechanism comprises a threaded rod, the threaded rod being insertable into the cover body, one end of the threaded rod being located outside the cover body, and the other end of the threaded rod being located inside the cover body; the first protective plate has a first connecting hole coinciding with the axis of the threaded rod, and the threaded rod is insertable into the first connecting hole.

[0010] Preferably, a magnet is fixed in the first connecting hole, and the threaded rod 410 is made of a material that can be attracted by the magnet.

[0011] Preferably, the end edge of the threaded rod 410 and / or the edge of the first connecting hole 122 is chamfered.

[0012] Preferably, a plurality of positioning hole groups are arranged on the upper surface of the base in a ring shape at equal distances from the axis of the cover, and the positioning hole groups are located on the outer side of the cover; one end of the threaded rod located on the outer side of the cover is rotatably connected to a rotating plate, the rotating plate is threadedly connected to a locking screw, and the locking screw extends into one of the positioning holes in the positioning hole group.

[0013] Preferably, each positioning hole in the positioning hole group is arranged at equal distances; the end of the locking screw is fixedly connected to an elastic needle; and an elastic needle accommodating groove is arranged in each positioning hole in the positioning hole group to accommodate the elastic needle.

[0014] Preferably, the first detection hole is a circular hole; the first detection hole is located on the side of the first protective plate; and a second protective plate is coaxially arranged on the upper side of the first detection hole, and the side of the second protective plate has a second detection hole.

[0015] Preferably, the edge of the first detection hole has a circular ring-shaped accommodating groove coaxial with the first detection hole; the second protective plate is a circular plate matching the size of the circular ring-shaped accommodating groove, and the second protective plate is arranged in the circular ring-shaped accommodating groove.

[0016] Preferably, the edge of the circular ring-shaped accommodating groove has a clamping block, the outer circular surface of the first protective plate has a slide, and one side of the slide is provided with a notch in communication with the slide, and the notch allows the clamping block to pass.

[0017] Compared with the prior art, the present application has the following advantages:

[0018] 1. The first protection plate is rotatable, a first detection hole is formed in the first protection plate, the first detection hole reaches the upper side of the to-be-detected area by rotating the first protection plate. The detection light passes through the first detection hole, thereby detecting the to-be-detected area. The detection light cannot pass through the first protection plate, so the area covered by the first protection plate is exempted from radiation hazards. After detecting a position, the first protection plate can be rotated to adjust the position of the first detection hole, thereby detecting other positions. Correspondingly, the first protection plate can cover the previously detected area, thereby avoiding radiation hazards at that position.

[0019] 2. The cover body and the first protection plate are connected by a detachable connecting mechanism. Through this arrangement, on the one hand: after the cover body and the first protection plate are connected, the cover body can drive the first protection plate to rotate, thereby enabling the first protection plate to rotate to the desired position; and this embodiment does not need to provide a movable door, and does not need to use hands to reach into the movable door to rotate the first protection plate, thereby avoiding frequent opening and closing of the movable door, which can cause the movable door to be damaged, thereby improving the service life of the entire device and avoiding the disadvantage that the gap of the movable door easily leaks detection light. On the other hand: after the cover body and the first protection plate are connected, the relative position of the cover body and the first protection plate does not change, thereby enabling the relative position of the detection head mounting bracket and the first detection hole to remain unchanged. When the cover body drives the first protection plate to rotate to the desired position, the cover body also correspondingly drives the detection head mounting bracket to reach the corresponding position. The relative position of the detection head mounting bracket and the first detection hole remains unchanged during each detection, thereby increasing the accuracy of detection.

DETAILED DESCRIPTION

[0036] In order to further understand the inventive content, characteristics and effects of the present application, the following examples are given, and are described in detail as follows with reference to the accompanying drawings.

[0037] The structure of the present application will be described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] Please refer to Figure 1 and Figure 2 The cancerous region scanning and detecting anti-radiation stereoscopic cover provided by the embodiment of the present application comprises a base 100 and a cover 200.

[0040] The base 100 is provided with a round hole 110, and the base 100 is provided with a rotatable first protective plate 120, the first protective plate 120 completely covers the round hole 110, the first protective plate 120 is provided with a first detection hole 121, and the first detection hole 121 coincides with the round hole 110.

[0041] Before detection, the base 100 is placed on the patient's body, and the region to be detected is located in the region surrounded by the round hole 110. Then the first protective plate 120 is rotated so that the first detection hole 121 is above the region to be detected. The detection light passes through the first detection hole 121, thereby scanning and detecting the region to be detected. The detection light cannot pass through the first protective plate 120, so the region covered by the first protective plate 120 can be exempted from the harm of the detection light radiation. After detecting a position, the first protective plate 120 can be rotated to adjust the position of the first detection hole 121, thereby detecting other positions.

[0042] In this embodiment, the first detection hole 121 can be inscribed in the round hole 110, and the diameter of the first detection hole 121 is greater than the radius of the round hole 110, so that the first detection hole 121 can completely display any region surrounded by the round hole 110 in the rotating condition.

[0043] The lower edge of the cover 200 is rotatably attached to the base 100. In an example, the lower edge of the cover 200 is in the same plane as the upper surface of the base 100. A ring-shaped groove is provided on the upper surface of the base 100, and the lower edge of the cover 200 is embedded in the ring-shaped groove, so that the detection light cannot leak from the joint between the cover 200 and the base 100. The cover 200 completely covers the first protective plate 120, i.e., the first protective plate 120 only works in the area wrapped by the cover 200, so as to protect the patient. The detection head mounting rack 300 is connected inside the cover 200 and is used to carry the detection head. In an example, the detection head mounting rack 300 can be an adjustable mounting rack, so as to facilitate adjustment of the direction of the detection head.

[0044] During detection, the position of the base 100 and the patient remains unchanged, but the position of the first detection hole 121 can change. Therefore, the cover 200 can be rotated to drive the detection head mounting rack 300 to the position of the first detection hole 121, so as to facilitate detection of the area to be detected wrapped by the first detection hole 121 by the detection head.

[0045] Embodiment 2

[0046] During the development process, the inventors encountered the following difficulties: First, because of the blocking of the cover 200, it is difficult for the user to rotate the first protective plate 120 to the desired position without providing a movable door on the cover 200. If a movable door is provided, the movable door is easy to break, thereby reducing the service life of the entire device. Moreover, detection light is easy to leak from the gap of the movable door. Second, during detection, if the position of the detection head and the first detection hole 121 do not correspond, the accuracy of the detection result will be affected. Therefore, even if the first protective plate 120 can reach the desired position, it is still necessary to rotate the cover 200 to drive the detection head mounting rack 300 to move to a position corresponding to the first detection hole 121, and in fact, it is difficult to accurately align the two each time during detection.

[0047] Based on the above difficulties, on the basis of Embodiment 1, please refer to Figure 3 , Figure 4 and Figure 5 , the cover 200 and the first protective plate 120 are connected by a detachable connecting mechanism 400.

[0048] Through the arrangement, the first problem is solved, that is, after the cover body 200 is connected with the first protective plate 120, rotating the cover body 200 can drive the first protective plate 120 to rotate, so that the first protective plate 120 can be rotated to the required position; and the embodiment does not need to be provided with a movable door, and the hand does not need to be inserted into the movable door to rotate the first protective plate 120, so that the movable door can be avoided from being frequently opened and closed and damaged, thereby improving the service life of the whole device, and avoiding the defect that the gap of the movable door is easy to leak detection light.

[0049] Meanwhile, the second problem is solved, that is, after the cover body 200 is connected with the first protective plate 120, the relative position of the cover body 200 and the first protective plate 120 is unchanged, so that the relative position of the detection head mounting frame 300 and the first detection hole 121 is unchanged. When the cover body 200 drives the first protective plate 120 to rotate to the required position, the cover body 200 also correspondingly drives the detection head mounting frame 300 to reach the corresponding position, and the relative position of the detection head mounting frame 300 and the first detection hole 121 is unchanged each time of detection, thereby increasing the accuracy of detection.

[0050] Meanwhile, the detachable connecting mechanism 400 can be operated, so that the connection between the cover body 200 and the first protective plate 120 is disconnected, and the cover body 200 or the first protective plate 120 can be individually rotated when needed.

[0051] It should be noted that, in order to enable the cover body 200 and the first protective plate 120 to rotate coaxially, the cover body 200 and the first protective plate 120 are coaxially arranged.

[0052] Moreover, it should be noted that, between the base 100 is placed to the working position, the user can pass through the round hole 110 from the lower side of the base 100, so that the first protective plate 120 can be rotated.

[0053] Specifically, the detachable connecting mechanism 400 includes a threaded rod 410, the threaded rod 410 is plug-in connected to the cover body 200, one end of the threaded rod 410 is located outside the cover body 200, and the other end of the threaded rod 410 is located inside the cover body 200; the first protective plate 120 is provided with a first connecting hole 122 coaxial with the axis of the threaded rod 410, and the threaded rod 410 can be inserted into the first connecting hole 122. The threaded rod 410 is inserted into the first connecting hole 122, the connection between the cover body 200 and the first protective plate 120 can be completed, and when the threaded rod 410 is separated from the first connecting hole 122, the connection between the cover body 200 and the first protective plate 120 can be disconnected.

[0054] It should be noted that, Figure 3 , Figure 4 , Figure 5In the embodiment, the position of the threaded rod 410 and the first connecting hole 122 do not correspond, but the cover 200 can rotate, so that the cover 200 is rotated to align the threaded rod 410 and the first connecting hole 122.

[0055] Further, the inventor finds that it is also not easy to align the threaded rod 410 and the first connecting hole 122 in the process of connecting the cover 200 and the first protective plate 120 through the threaded rod 410, so that the threaded rod 410 is not convenient to be inserted into the first connecting hole 122. Therefore, a magnet block 1221 is fixed in the first connecting hole 122, and the end of the threaded rod 410 that cooperates with the first connecting hole 122 is made of a material that can be attracted by the magnet. For example, the material can be iron, cobalt, nickel, or another magnet block with a polarity different from that of the magnet block. Through the above arrangement, when the end of the threaded rod 410 approaches the first connecting hole 122, the position of the threaded rod 410 and the first connecting hole 122 can be aligned by the attraction of the magnetic force.

[0056] Further, after the position of the threaded rod 410 and the first connecting hole 122 is aligned by the magnetic force, there can still be a certain deflection between them. A chamfer is arranged at the edge of the end of the threaded rod 410 and / or the edge of the first connecting hole 122. When there is a slight deflection between the position of the threaded rod 410 and the first connecting hole 122, the threaded rod 410 can be inserted into the first connecting hole 122 through the cooperation of the chamfer.

[0057] Embodiment 3

[0058] On the basis of the above embodiments, the inventor finds that even if the first protective plate 120 can reach the required position, it is difficult to fix the working position of the first protective plate 120 during work. In order to solve this problem, the following arrangement is made on the basis of the above:

[0059] Please refer to Figure 6 The upper surface of the base 100 is annularly and equidistantly provided with a positioning hole group 130 relative to the axis of the cover 200, the positioning hole group 130 includes a plurality of positioning holes, and the positioning hole group 130 is located outside the cover 200.

[0060] One end of the threaded rod 410 located outside the cover 200 is rotatably connected with a rotating plate 420 that can be locked, the rotating plate 420 is threadedly and rotatably connected with a locking screw 430, and the locking screw 430 extends into the positioning hole group 130 and is inserted into one of the positioning holes.

[0061] In this embodiment, the cover 200 and the first protective plate 120 can be locked by the locking screw 430 extending into the positioning hole, so that the cover 200 and the first protective plate 120 cannot move relative to the base 100.

[0062] Embodiment 4

[0063] Based on Embodiment 3, please refer to Figure 7 and Figure 8 Each positioning hole of the positioning hole group 130 is equidistantly arranged; the end of the locking screw 430 is fixedly connected with the elastic needle 440, and the elastic needle 440 jumps along the positioning hole group 130 in sequence in the process of movement of the locking screw 430. The elastic needle 440 emits a sound once jumping along the positioning hole group 130, and the angle of rotation of the cover body can be calculated by the number of sounds emitted by the elastic needle 440.

[0064] Correspondingly, the elastic needle accommodating groove 440-1 for accommodating the elastic needle 440 is arranged in each positioning hole of the positioning hole group 130, so that the elastic needle accommodating groove 440-1 can accommodate the elastic needle 440 when the locking screw 430 is inserted into the positioning hole, preventing the elastic needle 440 from being bent.

[0065] It should be noted that the positioning hole group 130 does not penetrate the base 100. On the one hand, if the positioning hole group 130 penetrates the base 100, the elastic needle 440 will pierce the elastic hole and pierce the patient, and on the other hand, if the positioning hole group 130 penetrates the base 100, the elastic needle accommodating groove 440-1 cannot be arranged.

[0066] Embodiment 5

[0067] Please refer to Figure 9 On the basis of the above embodiments, the positioning hole group 130 includes at least two circles of positioning holes, and the positioning holes in different circles are staggered.

[0068] In this embodiment, adjusting the inclination angle of the rotating plate 420 can make the locking screw 430 cooperate with the positioning holes in different circles.

[0069] When only one circle of positioning holes is arranged, there is always a gap between the positioning holes, so there is a minimum included angle between the two adjacent positioning holes. Assuming that the minimum included angle is 1°, when the cover body needs to be rotated by 0.5° and fixed, only one circle of positioning holes cannot achieve this purpose. The advantage of arranging multiple circles of positioning holes is that when 0.5° needs to be set, the locking screw 430 can be inserted into one of the positioning holes in another circle. Since the positioning holes in different circles are staggered, the cover body can be rotated by less than 1°, such as 0.5°, and fixed, so that this purpose can be achieved. Thus, the first protective plate 120 can be more accurately fixed at the desired position, and the position of the first detection hole 121 can be more accurately adjusted.

[0070] Further, if the angle of rotation is large, the angle between adjacent positioning holes is small, and the counting error may occur. For example, if the rotation angle is 40°, and the angle between adjacent positioning holes of a certain circle is 1°, the rotation is needed 40 times. At this time, even if the counting is performed by the vibration sound of the elastic needle 440 through the positioning hole, the error is easy to occur. Therefore, the following improvement is made:

[0071] The angles between the positioning holes of different circles are different. For example, the angle between adjacent positioning holes of the first circle is 1°, the angle between adjacent positioning holes of the second circle is 5°, and the angle between adjacent positioning holes of the third circle is 10°.

[0072] When the rotation angle of 40° is needed, the elastic needle 440 is only needed to cooperate with the positioning holes of the third circle, and the elastic needle 440 emits 4 vibration sounds when passing through the positioning hole, so that the cover 200 is rotated to the required position.

[0073] Embodiment 6

[0074] On the basis of the above embodiments, please refer to Figure 9 、 Figure 10 The following settings are made:

[0075] The first detection hole 121 is a circular hole; the first detection hole 121 is located on the side of the first protective plate 120; a second protective plate 500 is coaxially arranged on the upper side of the first detection hole 121, and the side of the second protective plate 500 has a second detection hole 510.

[0076] In this embodiment, when the area to be detected is smaller, the first protective plate 120 is first rotated to preliminarily wrap the area to be detected by the first detection hole 121, and then the second protective plate 500 is rotated to make the second detection hole 510 reach the upper side of the area to be detected, and the detection light passes through the second detection hole 510, so that the area to be detected is detected. The detection light cannot pass through the second protective plate 500, so the area covered by the second protective plate 500 can be exempted from the harm of radiation. In this embodiment, a part of the area of the first detection hole 121 is blocked by the second protective plate 500, so that the harm to the patient can be further reduced during detection.

[0077] It should be noted that in the development process, the inventor found that the cover 200 and the position on the patient's body are relatively fixed. Therefore, it is not that the cover 200 covers the corresponding position to achieve the purpose. For example, the base 100 is placed in the central abdomen and can be attached to the skin, but if the base 100 is skewed by a distance, there will be a gap between the base 100 and the patient's skin, and the detection light will leak from the gap. At this time, it is not applicable. Therefore, in the case that the position of the cover 200 cannot be changed at will, it is necessary to position the area to be detected by adjusting the position of the first detection hole 121 and / or the second detection hole 510.

[0078] And the inventor found that when the second detection hole 510 is tangent to the second protective plate 500 in the second detection hole 510; the diameter of the second detection hole 510 is greater than the radius of the second protective plate 500, the first protective plate 120 and the second protective plate 500 can be adjusted to any position that the first detection hole 121 can reach by rotating.

[0079] Further, please refer to Figure 11 , the edge of the first detection hole 121 has a circular accommodating groove 123 coaxial with the first detection hole 121; the second protective plate 500 is a circular plate matched with the size of the circular accommodating groove 123, and the second protective plate 500 is arranged inside the circular accommodating groove 123.

[0080] In this embodiment, the second protective plate 500 can rotate in the circular accommodating groove 123, and the circular accommodating groove 123 can restrict the activity space of the second protective plate 500, so that the second protective plate 500 can only rotate in the circular accommodating groove 123. And when the second protective plate 500 is not needed, it is convenient to disassemble the second protective plate 500.

[0081] Please refer to Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 , the edge of the circular accommodating groove 123 has a clamping block 1231, the outer circular surface of the second protective plate 500 has a slide 520, and one side of the slide 520 is provided with a gap 521 communicating with the slide 520, and the gap 521 allows the clamping block 1231 to pass through.

[0082] In this embodiment, when installing the second protective plate 500, the second protective plate 500 can be held by hand, the positions of the notch 521 and the clamping block 1231 are aligned, so that the clamping block 1231 enters the slide 520 through the notch 521, so that the clamping block 1231 and the slide 520 can be matched, through this setting, the second protective plate 500 cannot move up and down, but it does not affect its rotation, so that the second protective plate 500 can work more stably. And at the same time, the second protective plate 500 can still be disassembled.

[0083] The slide 520 includes an outer ring channel 520-1 and an inner ring channel 520-2, the inner ring channel 520-2 and the outer ring channel 520-1 are in communication with each other; the inner ring channel 520-2 and the outer ring channel 520-1 are at least partially not coincident in height position. For example, the inner ring channel 520-2 and the outer ring channel 520-1 form a convex or L shape, and the clamping block 1231 is also set to a corresponding shape. Through this setting, assuming that there is a gap between the second protective plate 500 and the circular ring-shaped accommodating groove 123, the second protective plate 500 will also shake while rotating in the circular ring-shaped accommodating groove 123, through the above setting, the second protective plate 500 can be prevented from shaking.

[0084] Embodiment 7

[0085] One of the problems of the above embodiment is that the second protective plate 500 is not easy to rotate. Therefore, on the basis of the above embodiment, please refer to Figure 11 、 Figure 12 、 Figure 13 、 Figure 14 , make the following settings:

[0086] The end of the clamping block 1231 is rotatably connected with a wheel 1232, the wheel 1232 is located in the inner ring channel 520-2, and is attached to the side wall of the inner ring channel 520-2, the inner ring channel 520-2 and the axis of the wheel 1232 are parallel.

[0087] Without setting the wheel 1232, when the second protective plate 500 rotates, the outer surface of the second protective plate 500 and the side wall of the circular ring-shaped accommodating groove 123 are in sliding connection. With the wheel 1232, the wheel 1232 and the side wall of the inner ring channel 520-2 are in rolling connection, reducing wear, making the second protective plate 500 rotate more smoothly.

[0088] In an embodiment, the clamping block 1231, the wheel 1232 and the notch 521 are all correspondingly provided with multiple groups, and are arranged in a ring shape at equal distances relative to the first detection hole 121, so that the second protective plate 500 rotates more smoothly.

[0089] Further, in the case that the cover 200 is not provided with a movable door, it is inconvenient to rotate the second protective plate 500 to adjust the position of the second detection hole 510. Therefore, the following arrangement is made:

[0090] The threaded rod 410 is perpendicular to the second protective plate 500, and the center of the upper surface of the second protective plate 500 is provided with a second connecting hole 530 which can be connected with the threaded rod 410.

[0091] By connecting the second connecting hole 530 with the threaded rod 410, the threaded rod 410 can be rotated outside the cover 200 to drive the second protective plate 500 to rotate.

[0092] It should be noted that in this embodiment, the second detection hole 510 cannot occupy the central position of the second protective plate 500, thereby providing space for the second connecting hole 530 to be arranged at the center of the second protective plate 500. Because the second protective plate 500 is not coaxial with the cover 200, the second protective plate 500 cannot be driven to rotate by rotating the cover 200. Therefore, the threaded rod 410 can only be inserted into the central position of the second protective plate 500, and the second protective plate 500 is driven to rotate by rotating the threaded rod 410.

[0093] However, because the second protective plate 500 itself can rotate, and in this embodiment, the wheel 1232 is arranged, the second protective plate 500 is convenient to rotate, and when the threaded rod 410 contacts the second connecting hole 530, the second connecting hole 530 also rotates in the same direction when the threaded rod 410 rotates, thereby making it inconvenient to connect the threaded rod 410 with the second connecting hole 530. In order to solve this problem, please refer to Figure 15 , the following arrangement is made:

[0094] The clamping block 1231 is provided with an inclined pawl 1231-1, the wheel 1232 is provided with an inclined ratchet tooth 1232-1, and the pawl 1231-1 and the ratchet tooth 1232-1 are matched.

[0095] In this embodiment, the cooperation of the pawl 1231-1 and the ratchet tooth 1232-1 makes the wheel 1232 only rotate in one direction. Since the wheel 1232 and the second protective plate 500 rotate together, when the wheel 1232 is clamped and cannot move, the second protective plate 500 is also difficult to rotate, and therefore the second protective plate 500 can only rotate in one direction. When the second protective plate 500 rotates in the opposite direction, the wheel 1232 will hinder the reverse rotation. Through this arrangement, during the process of screwing the threaded rod 410 into the second connecting hole 530, the second protective plate 500 cannot rotate in the direction in which the threaded rod 410 rotates, thereby facilitating the connection of the threaded rod 410 with the second connecting hole 530.
