DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] like Figure 1 and Figure 2 As shown, a motion monitoring system for a ring-shaped medical device includes: a telescopic component 100, a first side ring 200, a second side ring 300 and a mounting adjustment component 400, forming a flat independent ring structure.

[0050] like Figure 3 and Figure 4 As shown, the telescopic assembly 100 includes a first shell 101, a knob 105 and a locking piece 106. The first shell 101 is rotatably connected to the middle of the first gear 102, and the first rack 103 and the second rack 104 are meshed on the first gear 102; the knob 105 is rotatably connected to the top of the first shell 101, and the knob 105 is used to drive the first gear 102 to rotate. The locking piece 106 is set at the bottom of the knob 105, and the locking piece 106 is used to lock the position of the first gear 102; the first gear 102 is driven by the knob 105 to push the first rack 103 and the second rack 104 to expand or shrink in relative directions, thereby adjusting the circumference of the independent annular structure, and locking it through the locking piece 106 to ensure that the independent annular structure can be stably mounted in the aperture of the medical device.

[0051] like Figure 1 and Figure 2As shown, the first side ring 200 and the second side ring 300 are respectively fixed on both sides of the telescopic component 100, the bottom end of the first side ring 200 extends into the first shell 101 and is fixedly connected to the first rack 103, and the bottom end of the second side ring 300 extends into the first shell 101 and is fixedly connected to the second rack 104; connecting the first side ring 200 and the second side ring 300 to the first rack 103 and the second rack 104 inside the telescopic component 100 can ensure that the first side ring 200 and the second side ring 300 can move synchronously and smoothly when adjusting the circumference of the independent annular structure.

[0052] like Figure 1 and Figure 2 As shown, the installation and adjustment component 400 is connected to the top between the first side ring 200 and the second side ring 300. Through the setting of the installation and adjustment component 400, when the 3D imaging component 500 is initially installed, the position of the 3D imaging component 500 can be flexibly and symmetrically adjusted to achieve multi-angle installation. A plurality of 3D imaging components 500 are installed in the installation and adjustment component 400, and a plurality of 3D imaging components 500 are arranged on the independent ring structure to achieve multi-angle monitoring on an arc surface, and to achieve monitoring with a large field of view through the complementary fields of view of multiple angles.

[0053] like Figure 5 As shown, the locking member 106 includes a support 1061 and a spring 1063. The support 1061 is rotatably connected in the first shell 101. The bottom of the support 1061 is fixedly connected with an insertion rod 1062, and the insertion rod 1062 is inserted in the middle of the first gear 102; the spring 1063 is fixedly connected to the top of the support 1061, and the top of the spring 1063 abuts against the bottom of the knob 105; the top of the support 1061 is circumferentially equidistantly provided with a plurality of limiting holes 1064, and the bottom of the knob 105 is circumferentially equidistantly provided with a plurality of limiting rods, which are located directly above the limiting holes 1064. When it is necessary to adjust the telescopic assembly 100, the knob 105 can be pressed down to compress the spring 1063, and the limiting rod can be inserted into the limiting hole 1064. The first gear 102 can be driven to rotate by rotating the knob 105. After the adjustment is completed, the knob 105 is released, and the elastic force of the spring 1063 pushes the knob 105 to move the limiting rod away from the limiting hole 1064, thereby achieving locking.

[0054] In some embodiments, the locking member 106 is a ratchet ring, which drives the knob 105 to rotate and lock it in a desired position when the knob 105 is rotated; and when an attempt is made to rotate in the opposite direction, the ratchet ring prevents its movement, thereby achieving stable locking.

[0055] Due to the limitations of the structural characteristics of the ring-structured medical device, it is difficult to ensure effective monitoring field of view and monitoring accuracy through external monitoring equipment. In order to ensure that the aperture size of the ring structure is not excessively interfered with by other external equipment, the external monitoring equipment cannot be directly installed inside the ring-structured medical device due to size and other reasons. For this reason, multiple 3D imaging components 500 are symmetrically arranged in the independent ring structure.

[0056] like Figure 6 As shown, the installation and adjustment component 400 includes a second shell 401, and a second gear 402 is rotatably connected to the middle part of the second shell 401, and a third rack 403 and a fourth rack 404 are meshed on the second gear 402; the third rack 403 is fixedly connected to the top of the first side ring 200 through one of the 3D imaging components 500, and the fourth rack 404 is fixedly connected to the top of the second side ring 300 through another 3D imaging component 500.

[0057] In some embodiments, the 3D imaging assembly 500 is symmetrically placed inside the independent annular structure to achieve multi-angle monitoring on an arc surface, and to achieve monitoring of a large field of view through the complementary fields of view at multiple angles. Inside the independent annular structure, the adjustment assembly 400 is installed to adjust the position of the 3D imaging assembly 500. According to the aperture size of the medical device with different annular structures, the position of the 3D imaging assembly 500 can be flexibly and symmetrically adjusted during the initial installation to achieve multi-angle installation.

[0058] The multiple angles proposed in this application are defined based on the actual number of 3D imaging components 500. The angle is defined as the angle between any two 3D imaging components 500. For medical devices with different aperture sizes, the angles between the 3D imaging components 500 are generally equal, and the angles between the outermost 3D imaging components 500 generally do not exceed 180 degrees.

[0059] like Figure 7 As shown, the 3D imaging component 500 includes a shell 501, and a circuit board 504 is fixedly connected to the inside of the shell 501; the 3D imaging component 500 includes two CMOS-based image sensor modules 502 and a projector module 503 that uses a low-power infrared dot matrix for random speckle projection. In order to reduce the volume space occupied by each module, the present invention proposes to plan the control circuits of the CMOS image sensor module 502 and the projector module 503 on the same circuit board 504 through integrated circuit control, thereby reducing the structural volume of the circuit driving part and realizing the function of integrated control of the 3D imaging component 500. The circuit board 504 is integrated with a USB3.0 interface to realize the functions of simultaneous power supply and data transmission.

[0060] At the same time, in order to ensure that the projected speckle does not affect the patient's experience during close-range monitoring, a low-power infrared speckle solution is adopted, which is invisible to the patient.

[0061] like Figures 8 to 10 As shown, in view of the different radiation sources and magnetic field ranges of different annular structure medical devices, a monitoring system with a fixed monitoring field of view angle is difficult to ensure that the requirements of the monitoring area and field of view are still met after being installed in an effective position without affecting the radiation source and magnetic field energy. An elevation adjustment component 600 is provided on the outside of the 3D imaging component 500 for adjusting the angle of the 3D imaging component 500.

[0062] After the 3D imaging component 500 is initially installed, the pitch angle of the 3D imaging component 500 is adjusted by the pitch angle adjustment component 600 to ensure that the field of view center of each 3D imaging component 500 points to the isocenter position, and the combined field of view of multiple 3D imaging components 500 can completely cover the required field of view range.

[0063] The pitch angle adjustment assembly 600 includes a fixed body 601, a bracket 602, a turbine 603, an adjustment member 604 and a worm 605. The bracket 602 is rotatably connected in the fixed body 601, and the fixed body 601 is fixedly connected to the outside of the 3D imaging assembly 500. The turbine 603 is fixedly connected to one side of the bracket 602. The adjustment member 604 is rotatably connected to the fixed body 601. The worm 605 is fixedly sleeved on the outer surface of the adjustment member 604, and the worm 605 is meshed with the turbine 603. The adjustment member 604 is a high-damping screw. By rotating the high-damping screw, the turbine 603 is driven to rotate through the worm 605, thereby adjusting the pitch angle of the 3D imaging assembly 500. The high-damping design ensures the stability of the 3D imaging assembly 500 after the angle is adjusted.

[0064] A rotating shaft 606 is fixedly connected to both sides of the bracket 602, and a fixing hole 608 is provided on both sides of the fixed body 601. The rotating shaft 606 is rotatably connected in the fixing hole 608. The cooperation between the rotating shaft 606 and the fixing hole 608 provides stable support for the rotation of the bracket 602, ensuring that the bracket 602 can rotate steadily and smoothly when the 3D imaging component 500 adjusts the pitch angle.

[0065] Both sides of the bracket 602 are fixedly connected with positioning pins 607, and both sides of the fixed body 601 are provided with arc grooves 609. The positioning pins 607 are slidably connected in the arc grooves 609. The sliding of the positioning pins 607 in the arc grooves 609 can limit the rotation range of the bracket 602 and ensure that the pitch angle of the 3D imaging component 500 is adjusted within a predetermined range.

[0066] A receiving groove 610 is provided on the side of the bracket 602, and the worm 605 is located inside the receiving groove 610, which can more effectively utilize the space on the fixed body 601, making the pitch angle adjustment assembly 600 more compact and reasonable in structure.

[0067] like Figure 2-3 As shown, a motion monitoring system for a ring-shaped medical device also includes a control board 700, which is fixed inside the first housing 101. The control board 700 is responsible for receiving, processing and sending various instructions and data. A high-performance microprocessor, memory, input and output interface and other components are integrated to achieve effective control of various parts of the system. The control board 700 is fixed inside the first housing 101, which ensures the stability of its structure and facilitates electrical connection with the 3D imaging component.

[0068] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
