Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and more particularly, to a bedside cart, a component, and an interstitial hyperthermia system for use in conjunction with a medical imaging device. Background Art

[0002] In modern medical practice, high-end medical imaging devices such as magnetic resonance imagers and computed tomography (CT) scanners often need to cooperate with various medical devices in actual clinical applications to improve the efficiency and accuracy of diagnosis and treatment. Specifically, the current movable patient platforms of MRI and CT scanners lack specially designed fixed points, which makes it difficult to effectively fix and position medical devices, such as fiber optic drive mechanisms, during complex surgeries or diagnoses, thus affecting the comprehensive application efficiency of medical devices.

[0003] In related technologies, for example, in the application of fiber optic drive mechanisms in fields such as neurosurgery, precise fixation near the patient's head is required to ensure a constant relative position with the patient's head during the surgery. When the patient lies on the movable patient platform in the MRI room and the movable patient platform moves within the MRI bore for scanning, the optical fiber and the fiber optic drive mechanism must be able to move synchronously to maintain their relative position with the patient's head unchanged.

[0004] However, in reality in related technologies, many movable patient platforms are not designed with dedicated positions for fixing these medical devices, which severely limits the applicability of medical devices. Summary of the Invention

[0066] Example 1

[0067] As Figure 1 shown, in an embodiment of this application, a bedside trolley for use in conjunction with a medical imaging device is provided. The medical imaging device includes a movable patient platform 9 for carrying a patient and an acquisition tunnel 10 for acquiring medical information of the patient;

[0068] The bedside trolley is for detachably connecting to the movable patient platform 9. The bedside trolley is arranged to be able to reciprocate within the acquisition tunnel 10 along with the movable patient platform 9. The bedside trolley is provided with a position adjustment device for installing and supporting medical devices and capable of adjusting the relative position between the medical devices and the patient on the movable patient platform 9.

[0069] Through the above, the bedside cart is detachably connected to the side of the movable patient platform 9 facing the acquisition tunnel 10 to ensure synchronous movement of the two. The position adjustment device not only enables the medical device to be stably installed on the bedside cart, but also enables precise adjustment of the position of the medical device. By adjusting the position of the medical device, the relative position between the medical device and the movable patient platform 9 can be adjusted. Thereby, the medical device can be accurately aligned with the patient according to the specific requirements of the operation or diagnosis. Even when the movable patient platform 9 and the bedside cart move in the acquisition tunnel 10, the stability and accurate positioning of the medical device can be maintained, greatly improving the accuracy and reliability of medical image acquisition.

[0070] Through the application of the position adjustment device and the bedside cart, the defect that the medical device cannot be applied on the movable patient platform without a dedicated fixed point is solved, greatly expanding the use scenario of the medical device, thereby improving the applicability of the medical device and ensuring that the medical device can exert its best performance in various medical environments, providing more accurate and safer medical services for patients.

[0071] As Figure 1 and Figure 2 shown, in the embodiment of the present application, the application of the optical fiber drive mechanism 11 in the field of neurosurgery is taken as an example for illustration, but its application scope is far more than this.

[0072] Specific to this example, the medical imaging device is a nuclear magnetic resonance instrument; the bedside cart is made of magnetic resonance compatible materials, and the magnetic resonance compatible materials include but are not limited to those made of PEEK, carbon fiber, and non-magnetic brass; the medical device is the optical fiber drive mechanism 11. The bedside cart is made of magnetic resonance compatible materials and can be safely used in a magnetic resonance (MRI) environment (including during magnetic resonance scanning), without interfering with the magnetic resonance imaging quality and without causing harm to patients and operators.

[0073] The bedside cart accurately fixes the optical fiber 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 and enters the MRI hole for scanning as the movable patient platform, the optical fiber and its optical fiber drive mechanism 11 must be able to move synchronously to maintain their relative position with the patient's head unchanged.

[0074] In the embodiment of the present application, the position adjusting device includes a mounting mechanism 2 for mounting and supporting the optical fiber transmission mechanism 11, a horizontal adjusting mechanism 3, and a height adjusting structure 4. Specifically, through the horizontal adjusting mechanism 3, the mounting mechanism 2 and the optical fiber transmission mechanism 11 can be moved along the length direction of the movable patient platform 9, and the mounting mechanism 2 and the optical fiber transmission mechanism 11 can also be moved along the width direction of the patient platform 9, so as to realize the omnidirectional relative position adjustment of the optical fiber transmission mechanism 11 relative to the movable patient platform 9 in the horizontal direction. Through the height adjusting structure 4, the mounting mechanism 2 and the optical fiber transmission mechanism 11 can be adjusted in the height direction, so as to realize the relative position adjustment of the optical fiber transmission mechanism 11 relative to the movable patient platform 9 in the vertical direction.

[0075] Further, the bedside cart includes a vehicle body 1; the horizontal adjusting mechanism 3 includes a front-back adjusting structure 5 and a left-right adjusting structure 6;

[0076] The front-back adjusting 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.

[0077] In the embodiment of the present application, the height adjusting structure 4 is arranged between the vehicle body 1 and the left-right adjusting structure 6, and the left-right adjusting structure 6 is arranged between the medical device and the height adjusting structure 4 along the width direction of the movable patient platform 9.

[0078] In other embodiments, the left-right adjusting structure 6 can also be arranged between the vehicle body 1 and the height adjusting structure 4, and the height adjusting structure 4 is arranged between the medical device and the left-right adjusting structure 6.

[0079] The left-right adjusting structure 6 is arranged between the mounting mechanism 2 and the height adjusting structure 4 along the width direction of the movable patient platform 9, and the left-right adjusting structure 6 is configured to drive the mounting mechanism 2 to generate a relative displacement along the width direction of the movable patient platform 9.

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

[0081] As Figure 1 and Figure 3 shown, in the embodiment of the present application, the front-back adjusting structure 5 includes:

[0082] A connecting member 51, which is used to form a detachable connection with the end of the movable patient platform 9; for example, mushroom fasteners, Velcro, suction cups, etc. can be used;

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

[0084] A 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 relatively fixed to the vehicle body 1.

[0085] Specifically, the first locking member 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 is provided with a through hole for the connecting rod 52 to pass through along the length direction of the connecting rod 52. The connecting rod 52 passes through the through hole in the locking seat and is slidably connected to the locking seat. The hand-tightening screw is threadedly connected to the locking seat. By rotating the knob portion of the hand-tightening screw, the nail head portion can extend into the through hole and apply a locking force to the connecting rod 52. When it is necessary to adjust the distance between the optical fiber transmission mechanism 11 and the movable patient platform 9, the medical staff only needs to loosen the hand-tightening screw, and then can adjust the distance between the vehicle body 1 and the movable patient platform 9 by sliding the connecting rod 52. After adjusting to a suitable position, after tightening the hand-tightening screw, the distance between the movable patient platform 9 and the vehicle body 1 can be fixed. It should be noted that a plurality of first locking members 53 can be arranged on the vehicle body 1 along the moving direction of the connecting rod 52. By applying a locking force to the connecting rod 52 through a plurality of hand-tightening screws, the stability between the locking seat and the connecting rod 52 can be improved. Of course, this is not restrictive, and it is also possible to only provide one first locking member 53.

[0086] Such as Figure 1 and Figure 4 shown, the left-right adjustment structure 6 includes:

[0087] A cross bar 61 is arranged 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 cross bar 61, preferably installed at the end of the cross bar 61. The mounting mechanism 2 can also be provided with two, and the two mounting mechanisms 2 are respectively installed at both ends of the cross bar 61;

[0088] The connecting seat 62 can be adjusted in height through the height adjustment structure 4, and is provided with a first through hole 621 for the cross bar 61 to pass through. In this application, the connecting seat 62 can change in the relative height direction with respect to the vehicle body 1, but cannot change in the relative horizontal direction. Of course, this is not restrictive. In other embodiments, it is also possible for the connecting seat 62 to be adjustable in the horizontal direction with respect 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 cross bar 61 to relatively fix the cross bar 61 and the connecting seat 62.

[0090] Through this structure, the optical fiber transmission mechanism 11 can be adjusted along the width direction of the patient platform 9, so as to realize the adjustment of the left and right positions of the patient's head, further improving the applicability of the device.

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

[0092] The limiting member 631 is provided with a second through hole 6311 for the cross bar 61 to pass through. 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 adjustment position where the cross bar 61 can 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 locking position, it can apply an extrusion force to the cross bar 61 through the second through hole 6311;

[0093] The adjusting member 632 is used to adjust the position of the limiting member 631 so that the position of the limiting member 631 can be switched between the adjustment position and the locking position.

[0094] Specifically, two cross bars 61 are provided and are parallel to each other. At the same time, the cross section of the cross bar 61 is set to be circular. Therefore, two first through holes 621 are also provided on the connecting seat 62, and the two cross bars 61 respectively pass through the two first through holes 621. Of course, this is not restrictive. The cross bar 61 can also be set as a rod body with a non-circular cross section.

[0095] For the limiting member 631, in this application, it is set as a limiting plate, and 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 is no special limitation on the second through hole 6311. The number thereof can be set to one or two. In this application, the case where the second through hole 6311 is set to one is taken as an example.

[0097] Furthermore, the adjusting assembly includes:

[0098] A compression spring 6321, which is arranged on one side of the limiting member 631 along the moving direction of the limiting member 631. The connecting seat 62 is provided with an avoidance opening on the side of the limiting member 631 away from the compression spring 6321. The side of the limiting member 631 away from the compression spring 6321 can pass through the avoidance opening. When the compression spring 6321 releases elastic potential energy, it can make the limiting member 631 located at the locking position; in the embodiment of the present application, the compression spring 6321 is located in the middle position. In other embodiments, the compression spring can also be arranged at the bottommost.

[0099] A flipping handle 6322, which is arranged at the avoidance opening and has a protruding part and a non-protruding part; when the flipping handle 6322 is rotated to make the protruding part face the avoidance opening, the protruding part can push the limiting member 631 to move to the adjusting position and can compress and store energy in the compression spring 6321; when the non-protruding part faces the avoidance opening, the compression spring 6321 can release elastic potential energy to drive the limiting member 631 to move to the adjusting position.

[0100] When it is necessary to adjust the relative position between the cross bar 61 and the connecting seat 62, the user can rotate the flipping handle 6322. The protruding part can apply pressure to the limiting member 631, so that the limiting member 631 can move towards the compression spring 6, making the first through hole 621 and the second through hole 6311 aligned, so that the cross bar 61 can be moved. At this time, the compression spring 6321 is in a state of compressed energy storage. When the optical fiber transmission mechanism 11 is adjusted to a suitable position, the user only needs to rotate the flipping handle 6322 again to make the non-protruding part rotate to face the avoidance opening, then the pressure on the limiting member 631 can be removed. The compression spring 6321 can release elastic potential energy, driving the limiting member 631 to move towards one side of the avoidance opening, making the first through hole 621 and the second through hole 6311 misaligned. The friction force between the inner wall of the second through hole 6311 and the side wall of the cross bar 61 when the limiting member 631 abuts makes the connecting seat 62 and the cross bar 61 fixed, thus achieving the effect of locking the position of the cross bar 61 and the connecting seat 62 to ensure that the optical fiber transmission mechanism 11 can have good stability during use.

[0101] Such as Figure 2 and Figure 6As shown, in the embodiment of the present application, the height adjustment structure 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 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 6 As shown, specifically, the locking structure 42 includes a fixing seat and a hand screw. The fixing seat is fixedly connected to the upper surface of the vehicle body 1. The vertical rod 41 is arranged in the vertical direction and passes through the fixing seat and the vehicle body 1 in sequence. The vertical rod 41 is slidably connected to the fixing seat in the vertical direction. A stopper is fixedly provided at the bottom of the vertical rod 41 below the vehicle body 1. The stopper limits the sliding of the vertical rod 41, so that the bottom of the vertical tube cannot be separated from the vehicle body 1. The hand screw is threadedly connected to the fixing seat. By turning the knob of the hand screw, the nail head can be inserted into the fixing seat to apply a locking force to the side wall of the vertical rod 41. When the relative height between the optical fiber transmission mechanism 11 and the patient platform needs to be adjusted, the medical staff only needs to loosen the hand screw to adjust the relative height between the optical fiber transmission mechanism 11 and the movable patient platform 9 by sliding the vertical rod 41. After adjusting to the appropriate position, tighten the hand screw to fix the relative height of the movable patient platform 9 and the optical fiber transmission mechanism 11. Specifically, two vertical rods 41 are provided and are parallel to each other, and the cross section of the vertical rod 41 is provided as a circle. Of course, this is not restrictive. When the cross section of the vertical rod 41 is provided as a circle, the number of the vertical rods 41 may be provided as more than two, and the vertical rod 41 may also be provided as a rod body with a non-circular cross section.

[0103] like Figure 4 and Figure 7 As shown, in the embodiment of the present 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 optical fiber transmission mechanism 11 to the support 8;

[0105] The support 8 is arranged between the quick-release and quick-install device 7 and the cross bar 61. A universal ball 81 for ball-jointed 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 arranged between the support 8 and the quick-release and quick-install device 7. The support 8 is fixedly connected to the end of the cross bar 61.

[0106] In the embodiment of the present application, the quick-release and quick-assembly device 7 can quickly install the optical fiber transmission mechanism 11 on the support 8, and can also quickly disassemble it after use, thus providing convenience for the assembly work of medical staff. The rotation of the universal ball 81 can realize the angular swing of the optical fiber transmission mechanism 11, so that the optical fiber transmission mechanism 11 can obtain a better optical fiber propulsion angle to meet the surgical requirements under different conditions. When the medical staff adjusts the angle of the optical fiber transmission mechanism 11, first unlock the universal ball 81 through the locking member 82, so that it can be rotated. When the optical fiber transmission mechanism 11 is rotated to the required angle, the medical staff then locks the universal ball 81 through the locking member 82 to ensure the stability of the optical fiber transmission mechanism 11 during daily use.

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

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

[0109] An active limiting mechanism 72, arranged on the base 71, the active limiting mechanism 72 having a limiting position and an unlocking position. In the limiting position, the active limiting mechanism 72 limits the mating portion 111 that slides into the sliding connection portion in the first direction; in the unlocking position, the mating portion 111 is suitable for sliding out of the sliding connection portion along the first direction.

[0110] In the embodiment of the present application, there is no special limitation on the specific structure of the sliding connection portion in the present application. The sliding connection portion can be either a slide rail structure or a slideway structure. When the sliding connection portion is set as a slide rail structure, the cross-section of the slide rail can be set as a T-shaped structure, an inverted trapezoidal structure, or a special-shaped structure; when the sliding connection portion is set as a slideway, the cross-section of the slideway can be set as an inverted T-shaped structure, a dovetail groove structure, or a special-shaped structure. Of course, the cross-sectional shapes mentioned above are only for illustrative purposes, and there are infinitely many possibilities in actual applications. Importantly, regardless of the structure adopted, the core element of the sliding connection portion is to effectively limit the movement of the optical fiber transmission mechanism 11 in other directions except the first direction to ensure the stability of the optical fiber structure after installation.

[0111] In the embodiment of the present application, there is no limitation on the specific shape of the movable limiting mechanism 72. For example, its shape can be trapezoidal, wedge-shaped, square, etc. When the mating portion 111 slides into the sliding connection portion, the movable limiting mechanism 72 can either be pressed to the unlocking position by the bottom surface of the mating portion 111 or be manually moved to the unlocking position by the user. When the mating portion 111 slides to the expected position, the movable limiting mechanism 72 can either automatically move to the limiting position to form a snap connection with the mating portion 111 or be moved to the limiting position manually.

[0112] Further, when the optical fiber transmission mechanism 11 moves to a predetermined position along the sliding connection portion through the mating portion 111, only by moving the movable limiting mechanism 72 to the limiting position can the movable limiting mechanism 72 form a snap connection with the mating portion 111, preventing the optical fiber transmission mechanism 11 from further moving along the sliding connection portion, thereby realizing the stable installation and fixation between the optical fiber transmission mechanism 11 and the base 71. When it is necessary to disassemble the optical fiber transmission mechanism 11, only by retracting the movable limiting mechanism 72 from the limiting position to the unlocking position can the optical fiber transmission mechanism 11 slide along the sliding connection portion, thus realizing disassembly. Through the above structure, the effect of quick disassembly and assembly of the optical fiber transmission mechanism 11 is achieved, effectively shortening the operation time, providing great convenience for doctors, and at the same time accelerating the surgical process.

[0113] In the embodiment of the present application, the sliding connection portion is set as a chute 711. Specifically, two parallel guide plates are fixedly arranged on the upper surface of the base 71 along the first direction. Guide grooves are formed along the first direction on the opposite sides of the two guide plates. A limiting plate covers above the guide plates, and the space between the two guide grooves is set as the chute 711. Through this structure, not only the stable fixation of both sides of the mating portion 111 is realized, but also the stability of the optical fiber transmission mechanism 11 during sliding and fixation with the base 71 is improved. Moreover, the setting of the limiting plate effectively restricts the upper surface of the mating portion 111, ensuring that the mating portion 111 will not separate from the base 71, thereby improving the stability of the optical fiber transmission mechanism 11 during use.

[0114] In the embodiment of the present application, a cavity is formed in the base 71 at the position where the movable limiting mechanism 72 is located. The cavity is communicated with the chute 711. The movable limiting mechanism 72 is located below the bottom surface of the chute 711 (i.e., in the cavity). The movable limiting mechanism 72 can either be arranged between the two guide grooves, or in any one of the guide grooves, or be respectively arranged in the two guide grooves. In the present application, it is preferably to arrange the movable limiting mechanism 72 in one of the guide grooves, which not only saves the space of the base 71 but also reduces the manufacturing cost of the device.

[0115] In an embodiment of the present application, the movable limiting mechanism 72 includes a clamping portion 721 and an operating portion 722. The clamping portion 721 is connected to the operating portion 722. By driving the operating portion 722, the clamping portion 721 can be switched between a limiting position and an unlocking position. Specifically, the limiting position is above the sliding groove 711, and the unlocking position is below the bottom of the sliding groove 711. When it is necessary to fix the optical fiber transmission mechanism 11, it is only necessary to move the clamping portion 721 from the bottom of the sliding groove 711 into the interior of the sliding groove 711, so that the clamping portion 721 is located at the limiting position, thereby realizing the clamping of the clamping portion 721 and the mating portion 111. The clamping portion 721 can move to the limiting position either by the structure of the movable limiting structure itself or by manual operation, and no limitation is imposed on this. When it is necessary to disassemble the optical fiber transmission mechanism 11, only an acting force needs to be applied to the operating portion 722. By the movement of the operating portion 722, the clamping portion 721 is driven to move, so that the clamping portion 721 returns to the unlocking position below the bottom of the sliding groove 711, and then the optical fiber transmission mechanism 11 can be slid to separate the mating portion 111 from the base 71, thereby realizing the disassembly work between the optical fiber transmission mechanism 11 and the base 71.

[0116] In a further optimization of the present application, the movable limiting mechanism 72 further includes a biasing member 723. Through the biasing force applied by the biasing member 723 to the clamping portion 721, it is ensured that the clamping portion 721 can automatically move upward to the limiting position and stably remain in the limiting position, so as to form a required tight clamping state with the mating portion 111, realizing the stable fixation of the optical fiber transmission mechanism 11. Specifically, when an acting force is applied to the clamping portion 721 or the operating portion 722 and the acting force overcomes the biasing force provided by the biasing member 723, the clamping portion 721 can be moved from the limiting position to the unlocking position, so that the mating portion 111 can continue to slide along the sliding groove 711. Once the acting force is removed, the biasing force can make the clamping portion 721 return to the limiting position again. By applying the biasing force to the clamping portion 721 by the biasing member 723, the clamping portion 721 can re - establish a stable connection with the mating portion 111, ensuring good stability of the optical fiber transmission mechanism 11 in the fixed state.

[0117] Furthermore, the biasing member 723 is provided as a reed. The reed is embedded inside the base 71. The engaging portion 721 is provided on the upper surface of the reed. One end of the reed extends out from inside the base 71. The end of the reed outside the base 71 is provided as the operating portion 722. When the user presses the operating portion 722, the reed can be deformed, thereby driving the engaging portion 721 to move to the unlocking position below the bottom of the sliding groove 711. When the reed is not pressed and the engaging portion 721 is aligned with the engaging portion 111, the reed resumes deformation, enabling the engaging portion 721 to be engaged and cooperate with the engaging portion 111. Of course, the structure of the biasing member 723 is not limited to the reed. For example, a combination of a connecting plate and an elastic member can also be used. Among them, the engaging portion 721 is placed on the upper surface of the connecting plate, and the operating portion 722 is located at one end of the connecting plate. The elastic member can be selected from various structures such as a torsion spring, a spring, etc.

[0118] In the embodiment of the present application, one end of the sliding groove 711 is provided as a groove entrance. The engaging portion 111 can only slide into the sliding groove 711 from the groove entrance end. The engaging portion 721 is provided with a guiding inclined surface facing the groove entrance side. Specifically, the guiding inclined surface is inclined downward gradually in the direction of the groove entrance. When the engaging portion 111 slides into the sliding groove 711, the engaging portion 111 will apply pressure to the guiding inclined surface of the engaging portion 721 gradually, prompting the engaging portion 721 to automatically retract to the unlocking position, thereby ensuring that the engaging portion 111 can slide smoothly along the sliding groove 711 without obstruction. During the sliding process of the engaging portion 111 in the sliding groove 711, it can automatically press the engaging portion 721 to the unlocking position. The user only needs to focus on the movement operation of the optical fiber transmission mechanism 11 and the engaging portion 111 without additional steps, greatly simplifying the installation process of the optical fiber transmission mechanism 11.

[0119] Further, the side of the engaging portion 721 away from the guiding inclined surface is provided as an engaging surface. A limiting block 712 is fixedly provided on the upper surface of the base 71. The limiting block 712 is located at the end of the sliding groove 711 away from the groove entrance. When the side wall of the engaging portion 111 abuts against the limiting block 712, the engaging portion 721 is exactly aligned with the engaging portion 111. Under the elastic action of the reed, the engaging portion 721 is engaged and cooperated with the engaging portion 111, thereby clamping the engaging portion 111 between the engaging surface and the limiting block 712. The limiting block 712 plays a role in blocking the engaging portion 111, making the engaging portion 111 unable to continue sliding along the sliding groove 711 after abutting against the limiting block 712, thereby improving the stability of the optical fiber transmission mechanism 11 during use.

[0120] In the embodiment of the present application, an installation cavity 713 is provided inside the base 71. A connecting column 715 is fixedly arranged on the inner top wall of the base 71 in the installation cavity 713. The installation cavity 713 penetrates through the lower surface of the base 71. A through hole is formed through one end of the reed away from the operation part 722. One end of the reed away from the operation part 722 is inserted into the installation cavity 713 from below the base 71, and the connecting column 715 passes through the through hole. The connecting column 715 plays a positioning role for the reed in the through hole, thereby realizing the positioning and fixing of the reed, and ensuring that the reed has good stability during use.

[0121] Further, a bottom plate 714 is further provided below the base 71. The bottom plate 714 is used to block the installation cavity 713. The bottom plate 714 is connected to the base 71 by threaded nails. Of course, the connection method between the bottom plate 714 and the base 71 is not limited to this, and other forms such as magnetic attraction, clamping, locking, welding, and pasting can also be used for connection and fixation.

[0122] In the embodiment of the present application, the connecting column 715 penetrates through the bottom plate 714 and extends below the bottom plate 714. The part of the connecting column 715 located below the bottom plate 714 is used to connect with the universal ball 81. The connecting column 715 can be connected to the universal ball 81 by means of threaded connection, welding, plugging, clamping, etc. In the present application, a threaded connection is processed on the circumferential side wall of the part of the connecting column 715 below the bottom plate 714. A connection hole is formed at the top of the universal ball 81, and the connection hole is a threaded hole. The connecting column 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, guarantees 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 fast.

[0123] As Figure 7 shown, in the embodiment of the present application, an assembly hole 83 is formed at the top of the support 8 along the inward extending direction. Both the universal ball 81 and the locking member 82 are installed in the assembly hole 83.

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

[0125] A ball sleeve 821, installed at the top of the assembly hole 83. The universal ball 81 is assembled below the ball sleeve 821. The ball sleeve 821 is provided with a through hole for a part of the top of the universal ball 81 to pass through;

[0126] A moving block 822, located below the universal ball 81. An arc-shaped surface capable of fitting with the bottom of the universal ball 81 is provided on the upper surface of the moving block 822. The moving block 822 can move along the length direction of the assembly hole 83 in the assembly hole 83. A guiding inclined surface is provided at the bottom of the moving block 822.

[0127] The inclined push block 823 is arranged below the moving block 822 and can move along a direction perpendicular to the length of the assembly hole 83. A wedge surface capable of cooperating with the guiding inclined surface is arranged at the top of the inclined push block 823. The inclined push block 823 has a fixed position moving towards the inner side of the assembly hole 83 and a rotating position moving towards the outer side of the assembly hole 83. When the inclined push block 823 moves to the fixed position, the inclined push block 823 can drive the moving block 822 to move upward, so that the universal ball 81 is locked between the ball sleeve 821 and the moving block 822.

[0128] Specifically, when it is necessary to lock the universal ball 81, the medical staff only needs to move the inclined push block 823 towards the inner side of the assembly hole 83. The inclined push block 823 can form a cooperation with the guiding inclined surface of the moving block 822 through its own wedge surface and drive 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, the medical staff only needs to move the inclined push block 823 towards the outer side of the assembly hole 83, and the moving block 822 can move downward by its own weight, thereby realizing the unlocking of the universal ball 81.

[0129] Furthermore, a rotating handwheel 8231 is arranged on the outer side of the assembly 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. A threaded structure is processed on the circumferential side wall of the connecting part and is threadedly connected to the support 8. Therefore, the medical staff only needs to rotate the rotating part of the rotating handwheel 8231 to drive the inclined push block 823 to adjust its position, and at the same time, it can ensure that the inclined push block 823 has good stability after being adjusted to a suitable position. It provides good convenience for the medical staff to adjust and lock the angle of the optical fiber transmission mechanism 11.

[0130] In the embodiment of the present application, the vehicle body 1 for cooperating with the medical imaging device further includes an optical fiber support 12 and a bracket 121. One end of the optical fiber support 12 is fixedly connected to the upper surface of the vehicle body 1, and the other end of the optical fiber support 12 is fixedly connected to the bracket 121. When the optical fiber is led out from the optical fiber transmission mechanism 11, the optical fiber support 12 supports the bracket 121 on the advancing route of the optical fiber, so that the bracket 121 can play a good role in the optical fiber. The optical fiber support 12 can be set as a rigid structure or a flexible structure. When the optical fiber support 12 is set as a flexible structure, it needs to be plastic, such as a bamboo joint tube, etc.
