Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a bedside cart, components, and interstitial hyperthermia system for use in conjunction with medical imaging equipment. Background Technology

[0002] In modern medical practice, high-end medical imaging equipment such as MRI and CT scanners often need to work in conjunction with various other medical devices to improve diagnostic efficiency and accuracy in clinical applications. Specifically, the mobile patient platforms of current MRI and CT scanners lack specially designed fixation points, making it difficult to effectively fix and position medical devices, such as fiber optic drive mechanisms, during complex surgeries or diagnoses, thus affecting the overall effectiveness of the medical equipment.

[0003] In related technologies, such as fiber optic drive mechanisms used in neurosurgery, it is necessary to precisely fix them near the patient's head to ensure a constant relative position during surgery. When the patient lies on a movable patient platform in the MRI room, the fiber optic cable and its drive mechanism must move synchronously as the platform moves within the MRI aperture for scanning to maintain their constant relative position with the patient's head.

[0004] However, in reality, many mobile patient platforms are not designed with dedicated locations for securing these medical devices, which severely limits their applicability. Utility Model Content

[0005] The purpose of this application is to provide a bedside cart, components, and interstitial hyperthermia system for use with medical imaging equipment, which aims to improve the applicability of medical devices when the mobile patient platform is not designed for a dedicated location to fix the medical devices.

[0006] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description or may be learned by practice of this application.

[0007] According to a first aspect of this application, a bedside cart for use with medical imaging equipment is provided, the medical imaging equipment including a mobile patient platform for carrying a patient and an acquisition tunnel for collecting patient medical information;

[0008] The bedside cart is detachably connected to the side of the movable patient platform facing the acquisition tunnel. The bedside cart is configured to move back and forth within the acquisition tunnel along with the movable patient platform.

[0022] A crossbar is provided along the width direction of the movable patient platform to drive the installation mechanism and the fiber optic transmission mechanism to move along the width direction of the movable patient platform.

[0023] The connecting seat is height-adjustable via the lifting adjustment mechanism and has a first through hole for the crossbar to pass through.

[0024] The second locking element is installed on the connecting seat and is used to apply a locking force to the crossbar, so that the crossbar is fixed relative to the connecting seat.

[0025] In one exemplary embodiment of this application, the second locking member includes:

[0026] A limiting member has a second through hole for the crossbar to pass through. The limiting member is parallel to one side of the first through hole and is slidably connected to the connecting seat. The limiting member has an adjustable position that allows the crossbar to slide when the first through hole and the second through hole are aligned, and a locked position when the first through hole and the second through hole are staggered. When the limiting member is in the locked position, it can apply a compressive force to the crossbar through the second through hole.

[0027] An adjusting member is used to adjust the position of the limiting member, so that the position of the limiting member can switch between the adjusting position and the locking position.

[0028] In one exemplary embodiment of this application, the adjusting member includes:

[0029] A compression spring is provided on one side of the limiting member along the moving direction of the limiting member. The connecting seat has a clearance opening on the side of the limiting member away from the compression spring. The side of the limiting member away from the compression spring can pass through the clearance opening. When the compression spring releases its elastic potential energy, it can make the limiting member position in the locked position.

[0030] A flip handle, located at the clearance opening, has a protruding part and a non-protruding part; when the flip handle is rotated so that the protruding part faces the clearance opening, the protruding part can push the limiting member to move to the adjustment position and can compress and store energy in the compression spring; when the non-protruding part faces the clearance opening, the compression spring can release elastic potential energy to drive the limiting member to move to the adjustment position.

[0031] In one exemplary embodiment of this application, the lifting adjustment mechanism includes a vertical rod capable of moving in a vertical direction and a locking structure for locking the vertical rod; the top of the vertical rod is fixedly connected to the connecting seat.

[0032] In one exemplary embodiment of this application, the installation mechanism includes: a quick-release and quick-install device and a support;

[0033] The quick-release and quick-install device is used to detachably connect the fiber optic transmission mechanism to the support.

[0034] The support is disposed between the quick-release and quick-install device and the crossbar. A universal ball joint for ball-joint connection between the support and the quick-release and quick-install device and a locking member for locking the rotation of the universal ball joint are provided between the support and the quick-release and quick-install device. The support is fixedly connected to the end of the crossbar.

[0035] In one exemplary embodiment of this application, the quick-release and quick-install device includes:

[0036] The base has a sliding connection portion extending along a first direction. The sliding connection portion is configured to allow the mating portion of the optical fiber transmission mechanism to slide into it along the first direction and to limit the mating portion in a second direction after the mating portion slides in. The second direction is perpendicular to the bottom surface of the sliding connection portion where the first direction is located.

[0037] A movable limiting mechanism is disposed on the base. The movable limiting mechanism has a limiting position and an unlocking position. In the limiting position, the movable limiting mechanism limits the mating part that slides into the sliding connection part in the first direction. In the unlocking position, the mating part is adapted to slide out of the sliding connection part along the first direction.

[0038] In an exemplary embodiment of this application, the sliding connection portion is configured as a slide groove; the movable limiting mechanism is located below the bottom of the slide groove, and the movable limiting mechanism includes a locking portion and an operating portion. The locking portion is connected to the operating portion, and the operating portion is driven to switch the locking portion between the limiting position and the unlocking position. In the limiting position, the locking portion extends from the bottom surface of the slide groove into the interior of the slide groove and forms a locking with the mating portion. In the unlocking position, the locking portion retracts to below the bottom surface of the slide groove.

[0039] In one exemplary embodiment of this application, the active limiting mechanism further includes a biasing member. At the limiting position, the biasing member applies a biasing force to the locking portion to lock the locking portion into the mating portion. By driving the operating part, the biasing force can be overcome, causing the biasing member to drive the locking portion to switch to the unlocking position.

[0040] In an exemplary embodiment of this application, the biasing member is a spring, the snap-fit ​​portion is disposed on the upper surface of the spring, and the operating portion is disposed at one end of the spring.

[0050] In the bedside cart provided in the example embodiment of this application for use with medical imaging equipment, the bedside cart is detachably connected to the side of the movable patient platform facing the acquisition tunnel, allowing the bedside cart to move synchronously with the movable patient platform. The position adjustment device not only allows the medical device to be mounted on the bedside cart but also adjusts its position to change the relative position between the medical device and the movable patient platform. This enables the medical device to precisely adjust its relative position to the patient according to surgical or diagnostic needs, ensuring stable and accurate positioning of the medical device even as the patient platform and bedside cart move within the acquisition tunnel during the medical imaging equipment's information acquisition process. This guarantees the accuracy and reliability of medical image acquisition. The aforementioned position adjustment device solves the applicability problem of medical devices on movable patient platforms without dedicated fixed points, thereby expanding the scope of application of medical devices.

[0068] Example 1

[0069] like Figure 1 As shown in the embodiment of this application, a bedside cart for use with medical imaging equipment is provided. The medical imaging equipment includes a mobile patient platform 9 for carrying patients and an acquisition tunnel 10 for collecting patients' medical information.

[0070] The bedside cart is detachably connected to the mobile patient platform 9. The bedside cart is configured to move back and forth within the acquisition tunnel 10 along with the mobile patient platform 9. The bedside cart is equipped with a position adjustment device for installing and supporting medical devices and for adjusting the relative position of the medical devices and the patient on the mobile patient platform 9.

[0071] As described above, the bedside cart is detachably connected to the side of the movable patient platform 9 facing the acquisition tunnel 10, ensuring synchronized movement of both. The position adjustment device not only allows the medical device to be securely mounted on the bedside cart but also enables precise control over its position. By adjusting the position of the medical device, the relative position between the medical device and the movable patient platform 9 can be adjusted. This allows the medical device to be precisely aligned with the patient according to the specific needs of the surgery or diagnosis. Even when the movable patient platform 9 and the bedside cart move within the acquisition tunnel 10, the stability and accurate positioning of the medical device remain, greatly improving the accuracy and reliability of medical image acquisition.

[0072] By utilizing position adjustment devices and bedside carts, the limitations of medical devices on mobile patient platforms lacking dedicated fixed points have been overcome. This greatly expands the application scenarios of medical devices, thereby improving their applicability and ensuring that they can perform at their best in various medical environments, providing patients with more precise and safer medical services.

[0073] like Figure 1 and Figure 2 As shown in the embodiments of this application, the application of the fiber optic transmission mechanism 11 in the field of neurosurgery is used as an example, but its application scope is far more than that.

[0074] In this specific example, the medical imaging equipment used is an MRI scanner; the bedside cart is made of MRI-compatible materials, including but not limited to PEEK, carbon fiber, and non-magnetic brass; the medical device is a fiber optic drive mechanism 11. The bedside cart, made of MRI-compatible materials, can be safely used in an MRI environment (including during MRI scanning) without interfering with MRI imaging quality or causing harm to patients or operators.

[0075] The bedside cart 1 precisely fixes the fiber optic drive mechanism 11 near the patient's head to ensure a constant relative position with the patient's head during the operation. When the patient lies on the movable patient platform in the MRI room, as the movable patient platform enters the MRI aperture for scanning, the fiber optic cable and its fiber optic drive mechanism 11 must be able to move synchronously to maintain their relative position with the patient's head.

[0076] In this embodiment, the position adjustment device includes a mounting mechanism 2, a horizontal adjustment mechanism 3, and a lifting adjustment mechanism 4 for mounting and supporting the fiber optic transmission mechanism 11. Specifically, the horizontal adjustment mechanism 3 allows the mounting mechanism 2 and the fiber optic transmission mechanism 11 to move along the length of the movable patient platform 9, or along the width of the patient platform 9, thereby enabling omnidirectional relative position adjustment of the fiber optic transmission mechanism 11 relative to the movable patient platform 9 in the horizontal direction. The lifting adjustment mechanism 4 allows for height adjustment of the mounting mechanism 2 and the fiber optic transmission mechanism 11, thereby enabling relative position adjustment of the fiber optic transmission mechanism 11 relative to the movable patient platform 9 in the vertical direction.

[0077] Furthermore, the bedside cart includes a cart body 1; the horizontal adjustment mechanism 3 includes a first adjustment structure 5 and a second adjustment structure 6;

[0078] The first adjustment structure 5 is arranged between the movable patient platform 9 and the vehicle body 1 along the length direction of the movable patient platform 9. The first adjustment structure 5 is configured to drive the vehicle body 1 to generate relative displacement along the length direction of the movable patient platform 9.

[0079] The second adjustment structure 6 is arranged between the mounting mechanism 2 and the lifting adjustment mechanism 4 along the width direction of the movable patient platform 9. The second adjustment structure 6 is configured to drive the mounting mechanism 2 to generate relative displacement along the width direction of the movable patient platform 9.

[0080] Since the fiber optic transmission mechanism 11 is mounted on the vehicle body 1 via the connecting mounting mechanism 2, when the first adjustment structure 5 adjusts the distance between the vehicle body 1 and the movable patient platform 9, the front-to-back position of the fiber optic transmission mechanism 11 relative to the patient lying on the movable patient platform 9 can be adjusted; when the second adjustment structure 6 adjusts the position of the fiber optic transmission mechanism 11 along the width direction, the left-to-right position of the fiber optic transmission mechanism 11 relative to the patient lying on the movable patient platform 9 can be adjusted.

[0081] like Figure 1 and Figure 3 As shown in the embodiment of this application, the first adjustment structure 5 includes:

[0082] The connector 51 is used to form a detachable connection with the end of the movable patient platform 9; for example, it can be a mushroom-shaped fastener, Velcro, or suction cup, etc.

[0083] A connecting rod 52 is disposed between the connecting member 51 and the vehicle body 1, and is fixedly connected to the connecting member 51. It can slide relative to the vehicle body 1 along the length direction of the movable patient platform 9.

[0084] The first locking member 53 is installed on the vehicle body 1 and is used to apply a locking force to the connecting rod 52 so that the connecting rod 52 is fixed relative to the vehicle body 1.

[0085] Specifically, the first locking component 53 includes a locking seat and a hand-tightening screw. The locking seat is fixedly connected to the upper surface of the movable patient platform 9. The locking seat has a through hole along the length of the connecting rod 52 for the connecting rod 52 to pass through. The connecting rod 52 passes through the through hole and slides through the locking seat. The hand-tightening screw is threaded onto the locking seat. By rotating the knob of the hand-tightening screw, the screw head can be inserted into the through hole and apply a locking force to the connecting rod 52. When it is necessary to adjust the distance between the fiber optic transmission mechanism 11 and the movable patient platform 9, medical personnel only need to loosen the hand-tightening screw to adjust the distance between the vehicle body 1 and the movable patient platform 9 by sliding the connecting rod 52. After adjusting to the appropriate position, tightening the hand-tightening screw will fix the distance between the movable patient platform 9 and the vehicle body 1. It is worth noting that multiple first locking members 53 can be provided on the vehicle body 1 along the moving direction of the connecting rod 52. By applying a locking force to the connecting rod 52 with multiple hand-tightening screws, the stability between the locking seat and the connecting rod 52 can be improved. Of course, this is not a limitation; it is also possible to provide only one first locking member 53.

[0086] like Figure 1 and Figure 4 As shown, the second adjustment structure 6 includes:

[0087] A crossbar 61 is provided along the width direction of the movable patient platform 9 and is used to drive the mounting mechanism 2 to move along the width direction of the movable patient platform. Specifically, the mounting mechanism 2 can be fixedly installed at any position on the crossbar 61, preferably at the end of the crossbar 61. The mounting mechanism 2 can also be provided as two, with the two mounting mechanisms 2 respectively installed at both ends of the crossbar 61.

[0088] The connecting seat 62 can be height adjusted by the lifting adjustment mechanism 4. It has a first through hole 621 for the crossbar 61 to pass through. In this application, the connecting seat 62 can change in the relative height direction relative to the vehicle body 1, but cannot change in the relative horizontal direction. Of course, this is not limiting. In other embodiments, it is also understandable that the connecting seat 62 can be adjusted in the horizontal direction relative to the vehicle body 1.

[0089] The second locking member 63 is installed on the connecting seat 62 and is used to apply a locking force to the crossbar 61 so that the crossbar 61 is fixed relative to the connecting seat 62.

[0090] This structure allows the fiber optic transmission mechanism 11 to be adjusted along the width of the patient platform 9, thereby enabling adjustment of the left and right position of the patient's head and further improving the applicability of the device.

[0091] like Figure 4 and Figure 5As shown, the second locking member 63 further includes:

[0092] The limiting member 631 has a second through hole 6311 through which the crossbar 61 passes. The limiting member 631 is arranged parallel to one side of the first through hole 621 and is slidably connected to the connecting seat 62. The limiting member 631 has an adjustable position that allows the crossbar 61 to slide when the first through hole 621 and the second through hole 6311 are aligned, and a locking position when the first through hole 621 and the second through hole 6311 are staggered. When the limiting member 631 is in the locked position, it can apply a compressive force to the crossbar 61 through the second through hole 6311.

[0093] Adjusting member 632 is used to adjust the position of limiting member 631 so that the position of limiting member 631 can switch between the adjusted position and the locked position.

[0094] Specifically, there are two crossbars 61 that are parallel to each other, and the cross section of the crossbars 61 is circular. Therefore, there are two first through holes 621 on the connecting seat 62. The two crossbars 61 pass through the two first through holes 621 respectively. Of course, this is not a limitation. The crossbars 61 can also be set as a rod with a non-circular cross section.

[0095] In this application, the limiting member 631 is configured as a limiting plate. Its position can be set inside or outside the connecting seat 62. In this application, the limiting member 631 is preferably set inside the connecting seat 62.

[0096] There are no special restrictions on the second through hole 6311. Its number can be set to one or two. In this application, we take setting the second through hole 6311 to one as an example.

[0097] Furthermore, the adjustment component includes:

[0098] A compression spring 6321 is provided on one side of the limiting member 631 along the moving direction of the limiting member 631. The connecting seat 62 has a clearance opening on the side of the limiting member 631 away from the compression spring 6321, through which the side of the limiting member 631 away from the compression spring 6321 can pass. When the compression spring 6321 releases its elastic potential energy, it can position the limiting member 631 in the locked position. In this embodiment, the compression spring 6321 is located in the middle position. In other embodiments, the compression spring can also be located at the bottom.

[0099] A flip handle 6322, located at the clearance opening, has a protruding part and a non-protruding part. When the flip handle 6322 is rotated so that the protruding part faces the clearance opening, the protruding part can push the limiting member 631 to the adjustment position and can compress and store energy in the compression spring 6321. When the non-protruding part faces the clearance opening, the compression spring 6321 can release elastic potential energy to drive the limiting member 631 to the adjustment position.

[0100] When it is necessary to adjust the relative position between the crossbar 61 and the connecting seat 62, the user can rotate the flip handle 6322. The protrusion can apply pressure to the limiting member 631, allowing the limiting member 631 to move towards the compression spring 6, aligning the first through hole 621 and the second through hole 6311. This allows the crossbar 61 to move. At this time, the compression spring 6321 is in a compressed and energy-storing state. After adjusting the fiber optic transmission mechanism 11 to the appropriate position, the user only needs to rotate the flip handle 6322 again to rotate the non-protruding part towards the... By clearing the opening, the pressure on the limiting member 631 can be removed, and the compression spring 6321 can release its elastic potential energy, causing the limiting member 631 to move to one side of the opening. This causes the first through hole 621 and the second through hole 6311 to be misaligned. The friction between the inner wall of the limiting member 631 and the side wall of the crossbar 61 when they abut against each other fixes the connecting seat 62 and the crossbar 61, thereby achieving a position locking effect on the crossbar 61 and the connecting seat 62, so as to ensure that the fiber optic transmission mechanism 11 has good stability during use.

[0101] like Figure 2 and Figure 6 As shown in the embodiment of this application, the lifting adjustment mechanism 4 includes a vertical rod 41 and a locking structure 42 for locking the vertical rod 41; the length of the vertical rod 41 is set in the vertical direction and it can slide relative to the vehicle body 1 in the vertical direction, and the top of the vertical rod 41 is fixedly connected to the connecting seat 62.

[0102] like Figure 1 and Figure 6As shown, specifically, the locking structure 42 includes a fixed seat and a hand-tightening screw. The fixed seat is fixedly connected to the upper surface of the vehicle body 1. The vertical rod 41 is arranged vertically and passes through the fixed seat and the vehicle body 1 in sequence. The vertical rod 41 is slidably connected to the fixed seat in the vertical direction. A stop is fixedly provided at the bottom of the vertical rod 41 below the vehicle body 1. The stop restricts the sliding of the vertical rod 41, preventing the bottom of the vertical rod from detaching from the vehicle body 1. The hand-tightening screw is threaded onto the fixed seat. By rotating the knob of the hand-tightening screw, the screw head can be inserted into the fixed seat to apply a locking force to the side wall of the vertical rod 41. When it is necessary to adjust the relative height between the fiber optic transmission mechanism 11 and the patient platform, medical staff only need to loosen the hand-tightening screw to adjust the relative height between the fiber optic transmission mechanism 11 and the movable patient platform 9 by sliding the vertical rod 41. After adjusting to the appropriate position, tightening the hand-tightening screw will fix the relative height between the movable patient platform 9 and the fiber optic transmission mechanism 11. Specifically, there are two vertical rods 41 that are parallel to each other, and the cross-section of the vertical rods 41 is circular. Of course, this is not a limitation. When the cross-section of the vertical rods 41 is circular, the number of vertical rods 41 can be more than two. The vertical rods 41 can also be a rod with a non-circular cross-section.

[0103] like Figure 4 and Figure 7 As shown in the embodiment of this application, the installation mechanism 2 includes: a quick-release and quick-install device 7 and a support 8.

[0104] The quick-release and quick-install device 7 is used to detachably connect the fiber optic transmission mechanism 11 to the support 8.

[0105] The support 8 is disposed between the quick-release and quick-install device 7 and the crossbar 61. A universal ball 81 for ball joint connection between the support 8 and the quick-release and quick-install device 7 and a locking member 82 for locking the rotation of the universal ball 81 are provided between the support 8 and the quick-release and quick-install device 7. The support 8 is fixedly connected to the end of the crossbar 61.

[0106] In this embodiment, the quick-release device 7 allows the fiber optic transmission mechanism 11 to be quickly installed on the support 8 and quickly disassembled after use, thus facilitating assembly work for medical personnel. The rotation of the universal ball 81 allows the fiber optic transmission mechanism 11 to swing at different angles, enabling it to achieve better fiber optic propulsion angles to meet surgical needs under various conditions. When medical personnel adjust the angle of the fiber optic transmission mechanism 11, they first unlock the universal ball 81 using the locking member 82, allowing it to rotate. Once the fiber optic transmission mechanism 11 is rotated to the desired angle, the medical personnel then lock the universal ball 81 using the locking member 82, ensuring the stability of the fiber optic transmission mechanism 11 during daily use.

[0107] like Figure 8 and Figure 9 and Figure 10 As shown, the quick-release and quick-install device 7 further includes:

[0108] The base 71 is provided with a sliding connection portion extending along a first direction. The sliding connection portion is configured to allow the mating portion 111 of the optical fiber transmission mechanism 11 to slide into the first direction and to limit the mating portion 111 in a second direction after the mating portion 111 slides into the first direction. The second direction is perpendicular to the bottom surface of the sliding connection portion where the first direction is located.

[0109] A movable limiting mechanism 72 is disposed on the base 71. The movable limiting mechanism 72 has a limiting position and an unlocking position. In the limiting position, the movable limiting mechanism 72 limits the mating part 111 that slides into the sliding connection part in the first direction. In the unlocking position, the mating part 111 is adapted to slide out of the sliding connection part along the first direction.

[0110] In this application embodiment, the specific structure of the sliding connection is not specifically limited. The sliding connection can be either a slide rail structure or a slide track structure. When the sliding connection is set as a slide rail structure, the cross-section of the slide rail can be a T-shaped structure, an inverted trapezoidal structure, or an irregular shape; when the sliding connection is set as a slide track, the cross-section of the slide track can be an inverted T-shaped structure, a dovetail groove structure, or an irregular shape. Of course, the cross-sectional shapes mentioned above are only illustrative examples, and there are infinite possibilities in actual applications. Importantly, regardless of the structure adopted, the core element of the sliding connection is to effectively limit the movement of the optical fiber transmission mechanism 11 in directions other than the first direction, ensuring the stability of the optical fiber structure after installation.

[0111] In this embodiment, the specific shape of the movable limiting mechanism 72 is not limited; for example, its shape can be trapezoidal, wedge-shaped, square, etc. When the mating part 111 slides into the sliding connecting part, the movable limiting mechanism 72 can be pressed to the unlocked position by the bottom surface of the mating part 111, or it can be moved to the unlocked position manually by the user. When the mating part 111 slides to the expected position, the movable limiting mechanism 72 can either automatically move to the limiting position to form a locking engagement with the mating part 111, or it can be moved to the limiting position manually.

[0112] Furthermore, when the fiber optic transmission mechanism 11 moves to the predetermined position along the sliding connection via the mating part 111, the movable limiting mechanism 72 only needs to be moved to the limiting position to engage with the mating part 111, preventing further movement of the fiber optic transmission mechanism 11 along the sliding connection, thus achieving a stable installation and fixation between the fiber optic transmission mechanism 11 and the base 71. When it is necessary to disassemble the fiber optic transmission mechanism 11, simply retract the movable limiting mechanism 72 from the limiting position to the unlocked position, and the fiber optic transmission mechanism 11 can slide along the sliding connection, thereby achieving disassembly. Through the above structure, the fiber optic transmission mechanism 11 can be quickly disassembled and assembled, effectively shortening the operation time, providing great convenience for doctors, and also accelerating the surgical process.

[0113] In this embodiment, the sliding connection is configured as a groove 711. Specifically, two parallel guide plates are fixed on the upper surface of the base 71 along a first direction. Guide grooves are chiseled on opposite sides of the two guide plates along the first direction. A limiting plate covers the guide plates, and the groove 711 is formed between the two guide grooves. This structure not only achieves stable fixation of both sides of the mating part 111, but also improves the stability of the fiber optic transmission mechanism 11 during sliding and fixing with the base 71. Furthermore, the limiting plate effectively constrains the upper surface of the mating part 111, ensuring that the mating part 111 will not separate from the base 71, thereby improving the stability of the fiber optic transmission mechanism 11 during use.

[0114] In this embodiment, the base 71 has a cavity at the location of the movable limiting mechanism 72, and the cavity is connected to the slide groove 711. The movable limiting mechanism 72 is located below the bottom surface of the slide groove 711 (i.e., inside the cavity). The movable limiting mechanism 72 can be disposed between two guide grooves, or in any one of the guide grooves, or in two guide grooves respectively. In this application, it is preferred to dispose of the movable limiting mechanism 72 in one of the guide grooves, which not only saves space on the base 71, but also reduces the manufacturing cost of the device.

[0115] In this embodiment, the movable limiting mechanism 72 includes a locking part 721 and an operating part 722. The locking part 721 is connected to the operating part 722, and the locking part 721 can be switched between a limited position and an unlocked position via the driving part and the operating part 722. Specifically, the limited position is located above the slide groove 711, while the unlocked position is located below the bottom of the slide groove 711. When it is necessary to fix the fiber optic transmission mechanism 11, it is only necessary to move the locking part 721 from the bottom of the slide groove 711 to the inside of the slide groove 711, so that the locking part 721 is in the limited position, thereby realizing the locking of the locking part 721 and the mating part 111. The locking part 721 can be moved to the limited position by the movable limiting structure itself, or it can be moved to the limited position by manual operation, without limitation. When it is necessary to disassemble the fiber optic transmission mechanism 11, simply apply force to the operating part 722. The movement of the operating part 722 will drive the locking part 721 to move, so that the locking part 721 returns to the unlocked position below the bottom of the slide groove 711. Then the fiber optic transmission mechanism 11 can be slid to separate the mating part 111 from the base 71, thereby realizing the disassembly of the fiber optic transmission mechanism 11 from the base 71.

[0116] In a further optimization of this application, the movable limiting mechanism 72 also includes a biasing member 723. The biasing force applied to the locking portion 721 by the biasing member 723 ensures that the locking portion 721 can automatically move upward to the limiting position and remain securely in the limiting position, thereby forming the required tight locking state with the mating portion 111 and achieving stable fixation of the fiber optic transmission mechanism 11. Specifically, when a force is applied to the locking portion 721 or the operating portion 722, and this force overcomes the biasing force provided by the biasing member 723, the locking portion 721 can be moved from the limiting position to the unlocking position, allowing the mating portion 111 to continue sliding along the slide groove 711. Once the force is removed, the biasing force allows the locking portion 721 to return to the limiting position. By applying a biasing force to the locking portion 721 by the biasing member 723, the locking portion 721 can re-establish a secure connection with the mating portion 111, ensuring good stability of the fiber optic transmission mechanism 11 in the fixed state.

[0117] Furthermore, the biasing member 723 is configured as a spring, which is embedded inside the base 71. A locking portion 721 is located on the upper surface of the spring, with one end of the spring extending from inside the base 71. The outer end of the spring on the base 71 is configured as an operating portion 722. When the user presses the operating portion 722, the spring deforms, causing the locking portion 721 to move to the unlocked position below the bottom of the slide groove 711. When the spring is not pressed and the locking portion 721 is aligned with the mating portion 111, the spring returns to its original shape, allowing the locking portion 721 to engage with the mating portion 111. Of course, the structure of the biasing member 723 is not limited to a spring. For example, a combination of a connecting plate and an elastic element can be used, where the locking portion 721 is located on the upper surface of the connecting plate, and the operating portion 722 is located at one end of the connecting plate. The elastic element can be a torsion spring, a spring, or other similar structures.

[0118] In this embodiment, one end of the slide groove 711 is configured as the groove inlet. The mating part 111 can only slide into the slide groove 711 from the groove inlet end. The locking part 721 is configured as a guide inclined surface facing the groove inlet. Specifically, the guide inclined surface is gradually inclined from top to bottom towards the groove inlet. When the mating part 111 slides into the slide groove 711, the mating part 111 will gradually apply pressure along the guide inclined surface of the locking part 721, causing the locking part 721 to automatically retract to the unlocked position, thereby ensuring that the mating part 111 can slide smoothly and without obstruction along the slide groove 711. The sliding process of the mating part 111 in the slide groove 711 can automatically press the locking part 721 to the unlocked position. The user only needs to focus on the movement operation of the fiber optic transmission mechanism 11 and the mating part 111, without additional steps, which greatly simplifies the installation process of the fiber optic transmission mechanism 11.

[0119] Furthermore, the engaging part 721 has an engaging surface on the side opposite to the guide inclined surface, and a limiting block 712 is fixed on the upper surface of the base 71. The limiting block 712 is located at the end of the slide groove 711 away from the groove inlet. When the side wall of the mating part 111 abuts against the limiting block 712, the engaging part 721 is precisely aligned with the mating part 111. Under the elastic action of the spring, the engaging part 721 and the mating part 111 complete the engaging engagement, thereby engaging the mating part 111 between the engaging surface and the limiting block 712. The limiting block 712 acts as a blocking force on the mating part 111, preventing the mating part 111 from continuing to slide along the slide groove 711 after abutting against the limiting block 712, thereby improving the stability of the fiber optic transmission mechanism 11 during use.

[0120] In this embodiment, the base 71 has an internal mounting cavity 713. A connecting post 715 is fixed to the inner top wall of the mounting cavity 713. The mounting cavity 713 penetrates the lower surface of the base 71. A through hole is provided at the end of the spring away from the operating part 722. The end of the spring away from the operating part 722 is inserted into the mounting cavity 713 from below the base 71, and the connecting post 715 passes through the through hole. The connecting post 715 plays a positioning role for the spring in the through hole, thereby realizing the positioning and fixing of the spring and ensuring good stability of the spring during use.

[0121] Furthermore, a base plate 714 is provided below the base 71. The base plate 714 is used to cover the mounting cavity 713. The base plate 714 is connected to the base 71 by threaded nails. Of course, the connection method between the base plate 714 and the base 71 is not limited to this. It can also be connected and fixed by magnetic attraction, snap-fit, locking, welding, or pasting.

[0122] In this embodiment, the connecting post 715 penetrates the base plate 714 and extends to the bottom of the base plate 714. The portion of the connecting post 715 located below the base plate 714 is used to connect with the universal ball 81. The connecting post 715 can be connected to the universal ball 81 by means of threaded connection, welding, plug-in, snap-fit, etc. In this application, the connecting post 715 has a threaded connection processed on the circumferential side wall of the portion below the base plate 714. The top of the universal ball 81 has a connection hole, which is a threaded hole. The connecting post 715 is connected to the universal ball 81 by means of threaded connection, which not only ensures the tight fixation between the base 71 and the support 8, ensuring the stability and reliability of the overall structure, but also provides great convenience for users, making the disassembly and installation of the base 71 easy and quick.

[0123] like Figure 7 As shown in the embodiment of this application, the top of the support 8 is provided with an assembly hole 83 in the inward extending direction, and the universal ball 81 and the locking member 82 are both installed in the assembly hole 83.

[0124] In this embodiment of the application, the locking member 82 includes:

[0125] A ball sleeve 821 is installed on the top of the mounting hole 83, and the universal ball 81 is mounted below the ball sleeve 821. The ball sleeve 821 has a through hole through which the top part of the universal ball 81 passes.

[0126] The movable block 822 is located below the universal ball 81. The upper surface of the movable block 822 is provided with an arc-shaped surface that can fit with the bottom of the universal ball 81. The movable block 822 can move along the length direction of the assembly hole 83 within the assembly hole 83. The bottom of the movable block 822 is provided with a guide slope.

[0127] An inclined push block 823 is disposed below the movable block 822 and can move along a direction perpendicular to the length of the mounting hole 83. The top of the inclined push block 823 is provided with a wedge-shaped surface that can cooperate with the guide inclined surface. The inclined push block 823 has a fixed position that moves inward to the mounting hole 83 and a rotating position that moves outward to the mounting hole 83. When the inclined push block 823 moves to the fixed position, the inclined push block 823 can drive the movable block 822 to move upward, so that the universal ball 81 is locked between the ball sleeve 821 and the movable block 822.

[0128] Specifically, when it is necessary to lock the universal ball 81, medical staff only need to move the inclined push block 823 towards the inside of the mounting hole 83. The inclined push block 823 can then cooperate with the guide inclined surface of the moving block 822 through its own wedge-shaped surface, driving the moving block 822 to move upward. When the inclined push block 823 moves to the fixed position, the universal ball 81 can be clamped between the ball sleeve 821 and the moving block 822. When it is necessary to unlock the universal ball 81, medical staff only need to move the inclined push block 823 towards the outside of the mounting hole 83. The moving block 822 can then move downward by its own weight, thereby unlocking the universal ball 81.

[0129] Furthermore, a rotating handwheel 8231 is provided on the outer side of the mounting hole 83 of the inclined push block 823. The rotating handwheel 8231 has a rotating part and a connecting part. The connecting part passes through the side wall of the support 8 and is rotatably connected to the inclined push block 823. The circumferential side wall of the connecting part is machined with a threaded structure and is threadedly connected to the support 8. Therefore, medical staff only need to rotate the rotating part of the rotating handwheel 8231 to drive the inclined push block 823 to adjust its position, while ensuring that the inclined push block 823 has good stability after being adjusted to the appropriate position. This provides medical staff with good convenience for adjusting and locking the angle of the fiber optic transmission mechanism 11.

[0130] In this embodiment, the vehicle body 1 used in conjunction with medical imaging equipment further includes a fiber optic bracket 12 and a support 121. One end of the fiber optic bracket 12 is fixedly connected to the upper surface of the vehicle body 1, and the other end of the fiber optic bracket 12 is fixedly connected to the support 121. When the optical fiber is led out from the fiber optic transmission mechanism 11, the fiber optic bracket 12 supports the support 121 on the fiber optic propulsion path, enabling the support 121 to function effectively for the optical fiber. The fiber optic bracket 12 can be configured as a rigid structure or a flexible structure. When the fiber optic bracket 12 is configured as a flexible structure, it needs to be malleable, such as a bamboo tube.
