[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0041] In the description of this utility model, it should be understood that the terms "length," "width," "thickness," "upper," "lower," "inner," "outer," and "axial," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] The following is for reference. Figures 1-11 Description of an interventional surgical control system 100 according to an embodiment of the present invention.

[0044] like Figure 1 As shown, the interventional surgery control system 100 of this utility model embodiment includes a drive stage 10, a quick-change box 20, and a quick-change mechanism 30.

[0045] It should be noted that the drive stage 10 is responsible for providing stable driving force. During interventional surgery, the drive stage 10 can analyze the motion parameters required by the doctor according to the doctor's operating instructions through algorithms. These motion parameters include, but are not limited to, speed, acceleration, etc., and convert these parameters into actual driving force, which is then transmitted to the operation of subsequent mechanical components.

[0046] The quick-change box 20 is an intermediate link connecting the drive stage 10 and surgical instruments (such as guide wires, catheters, stents, etc.). Through the detachable connection between the quick-change box 20 and the drive stage 10, the quick-change box 20 can be quickly replaced, thereby improving the instrument flexibility and ease of operation during interventional surgery.

[0047] The quick-change mechanism 30 is directly responsible for the quick connection and disconnection between the quick-change box 20 and the drive station 10. Specifically, the quick-change box 20 is detachably connected to the drive station 10 via the quick-change mechanism 30.

[0048] Among them, combined Figures 1-2 The quick-change mechanism 30 includes a locking member 1 and a pin 3. The locking member 1 has a movable groove 2, and one side of the movable groove 2 forms a socket 21. The pin 3 can be inserted into the movable groove 2 through the socket 21 and can slide within the movable groove 2 in a first direction.

[0049] In the above technical solution, the locking member 1 is installed on either the drive platform 10 or the quick-change box 20, and the locking member 1 is provided with a movable groove 2, with an insertion port 21 formed on one side of the movable groove 2. The movable groove 2 is divided into two parts along the first direction: a locking section 22 and a releasing section 23. Here, the first direction is the direction in which the quick-change box 20 is installed. Usually, the drive platform 10 is elongated, and here, the first direction is also the width direction of the drive platform 10. In some solutions, the first direction can also be the length direction of the drive platform 10, or there may be a certain angle between the first direction and the length direction. This utility model does not limit the specific orientation of the first direction. For ease of description, this application uses the width direction of the drive platform 10 as an example for description, and will not repeat it below.

[0050] The pin 3 is installed on the other of the drive table 10 or quick-change box 20. The pin 3 can be inserted into the movable slot 2 through the socket 21 and move in the movable slot 2 in the first direction.

[0051] Here, in order to achieve quick locking and release of the quick-change box 20 on the drive stage 10, the sliding of the pin 3 can be controlled by external operation or internal mechanism.

[0052] External manipulation can be achieved by the doctor directly pushing the pin 3 or the movable groove 2 itself to move the pin 3 and the movable groove 2 relative to each other.

[0053] Alternatively, the relative movement between the pin 3 and the movable groove 2 can be achieved by pushing the component connected to the pin 3 or by pushing the component connected to the movable groove 2.

[0054] For example, a slider can be provided on the quick-change box 20 or the drive table 10, and the slider is used to connect with the locking member 1 or the pin 3. When the slider is pushed, the locking member 1 or the pin 3 slides along the first direction, thereby moving the pin 3 within the movable groove 2 to the locking section 22 or the releasing section 23. It should be understood that the technical solution of this application is not limited to using a slider. In some solutions, a pull ring can also be provided on the quick-change box 20 or the drive table 10. For example, a pull ring is provided on the drive table 10, and the pull ring is connected to the locking member 1. When the pull ring is pulled, the locking member 1 slides along the first direction, thereby realizing the relative sliding of the pin 3.

[0055] The internal mechanism can be an electric push rod, an electromagnet, or other similar device. When the internal mechanism is an electric push rod, the push rod can be driven by a motor to move the pin 3 within the movable slot 2. When the internal mechanism is an electromagnet, an electromagnet can be installed on the drive platform 10 or the quick-change box 20. The magnetic force of the electromagnet can be controlled by the current to attract or repel the pin 3, thereby allowing it to slide within the movable slot 2.

[0056] See Figures 3-5The movable slot 2 includes a locking section 22 and a releasing section 23 arranged along a first direction: when the pin 3 slides along the first direction to the locking section 22, the pin 3 is engaged at the locking section 22, thereby locking the quick-change box 20 onto the drive table 10. When the pin 3 slides along the first direction to the releasing section 23, the pin 3 can be pulled out from the socket 21, thereby releasing the quick-change box 20 from the drive table 10. The pin 3 is disposed on one of the drive table 10 and the quick-change box 20, and the locking member 1 is disposed on the other.

[0057] To ensure that the pin 3 is firmly fixed in the locking section 22 and to prevent it from sliding in the first direction, the locking section 22 can be fixed in a variety of ways, such as structural fixing, magnetic fixing or friction fixing.

[0058] In some alternative embodiments, the locking segment 22 secures the pin 3 structurally. For example, a protrusion or groove is constructed inside the locking segment 22, and a structure adapted to the protrusion or groove is constructed on the pin 3 to form a snap-fit ​​fixation. When the pin 3 slides to the locking segment 22, the protrusion or groove engages the pin 3, preventing it from sliding in the first direction. Alternatively, an elastic locking arm is provided inside the locking segment 22, which engages the pin 3 when it slides to the locking segment 22, providing additional fixing force. Or, a wedge-shaped structure is constructed inside the locking segment 22, which gradually increases friction as the pin 3 slides to the locking segment 22, making it difficult for the pin 3 to slide out.

[0059] In some alternative embodiments, a magnet is provided inside the locking section 22 or on the pin 3, and the pin 3 is fixed in the locking section 22 by magnetic force. When the pin 3 slides into the locking section 22, the attraction force generated by the magnet firmly fixes the pin 3. Alternatively, an electromagnet is provided inside the locking section 22, and the magnetic force of the electromagnet is controlled by current to achieve the fixing and releasing of the pin 3. When it is necessary to fix the pin 3, the electromagnet is energized to generate magnetic force; when it is necessary to release the pin 3, the power is de-energized to deactivate the electromagnet.

[0060] In some alternative embodiments, a high-friction material, such as a rubber or Teflon component, is disposed inside the locking section 22. When the pin 3 slides into the locking section 22, the high-friction material not only increases the friction but also creates an interference fit between the locking section 22 and the pin 3, thereby achieving a secure fixation of the pin 3.

[0061] The release section 23 is part of the movable slot 2 and is located opposite the locking section 22. The purpose of the release section 23 is to allow the pin 3 to slide easily in the first direction and eventually be pulled out of the socket 21.

[0062] Optionally, the inner surface of the release section 23 is configured with a smoother shape. This reduces friction when the pin 3 slides, ensuring smooth movement of the pin 3.

[0063] In the quick-change mechanism 30, the pin 3 is set on one of the drive table 10 and the quick-change box 20, and the locking element 1 is set on the other.

[0064] In some specific technical solutions, combined with Figure 1 , Figures 6-7 The pin 3 is mounted on the drive platform 10, while the locking element 1 is mounted on the quick-change box 20. Thus, the pin 3 is fixed to a certain position on the drive platform 10, or it is fixedly connected to the drive platform 10 through intermediate components such as support members, or the pin 3 and the drive platform 10 are integrally formed. The locking element 1 can be integrally formed directly on the quick-change box 20, or the locking element 1 can be connected to the quick-change box 20 through an intermediate structure.

[0065] Based on the above technical solution, the installation process of a specific quick-change box 20 is described below:

[0066] First, align the quick-change box 20 with the drive stage 10, and align the pin 3 with the socket 21 on the locking member 1.

[0067] Then, insert the pin 3 into the movable slot 2 through the socket 21.

[0068] Next, the pin 3 is pushed to slide along the first direction to the locking section 22. When the pin 3 reaches the locking section 22, the structure of the locking section 22 jams the pin 3, preventing it from sliding along the first direction, thereby locking the quick-change box 20.

[0069] The disassembly process is the exact opposite of the installation process: the pin 3 is pushed to slide along the first direction to the release section 23. When the pin 3 reaches the release section 23, the smooth structure of the release section 23 allows the pin 3 to slide freely.

[0070] Next, pull out the quick-change box 20 so that the pin 3 is completely pulled out from the socket 21 of the locking member 1, thereby releasing the quick-change box 20 from the drive table 10.

[0071] In some specific technical solutions, the pin 3 is located on the quick-change box 20, while the locking element 1 is located on the drive platform 10. In this technical solution, the installation and disassembly process of the quick-change box 20 is similar to that of the previous technical solution, and therefore will not be described in detail.

[0072] To improve the stability of the connection between the quick-change box 20 and the drive stage 10, at least two pins 3 are used, and the number of locking elements 1 is adapted to the number of pins 3. By setting multiple pins 3 and locking elements 1, a firm connection between the quick-change box 20 and the drive stage 10 is ensured.

[0073] Combination Figure 1When there are three pins 3, the three pins 3 are configured not to be on the same straight line. This layout can further enhance the multi-directional stability and torsional resistance of the connection between the quick-change box 20 and the drive platform 10.

[0074] In some optional embodiments, to improve the stability of the connection and the flexibility of operation, the locking member 1 is provided with two movable slots 2. The drive platform 10 is also provided with two pins 3 at positions corresponding to the movable slots 2. These two pins 3 match the movable slots 2 on the locking member 1, allowing the pins 3 to smoothly insert into the corresponding movable slots 2 when the locking member 1 is engaged with the drive platform 10. This design not only ensures a stable connection between the locking member 1 and the drive platform 10, but also allows the locking member 1 to be fine-tuned within a certain range to adapt to different working requirements or compensate for minor errors during installation.

[0075] According to some embodiments of this utility model, such as Figure 8 As shown, a pin groove 31 is provided on the outer peripheral surface of the pin 3. Combined with... Figures 3-5 The movable groove 2 has a retaining plate 221 on the inner circumferential surface of the locking section 22. When the pin 3 slides to the locking section 22, at least a portion of the retaining plate 221 is engaged in the pin groove 31. When the pin 3 slides to the release section 23, the retaining plate 221 is disengaged from the pin groove 31.

[0076] In the above technical solution, when the pin 3 slides to the locking section 22, the pin 3 is fixed to the locking member 1 through the cooperation of the retaining plate 221 and the pin groove 31, thereby achieving a fixed connection between the quick-change box 20 and the drive table 10. The depth and width of the pin groove 31 are adapted to the retaining plate 221, which ensures that the retaining plate 221 is firmly engaged without affecting the sliding performance of the pin 3.

[0077] Optionally, the pin groove 31 can be an annular groove. An annular groove refers to a complete groove surrounding the outer circumference of the pin 3. The annular groove design makes the pin 3 more evenly and stably fixed within the locking section 22. Alternatively, the pin groove 31 can also be a semi-annular groove. A semi-annular groove refers to a groove formed around the outer circumference of the pin 3. The semi-annular groove design ensures the pin 3 is fixed within the locking section 22 while maintaining the structural strength of the pin 3, preventing deformation of the semi-annular groove, and improving the reliability of the fixation between the retaining plate 221 and the pin groove 31.

[0078] Optionally, the number of pin slots 31 is at least one, and the number of retaining plates 221 is adapted to the number of pin slots 31. When the number of pin slots 31 and retaining plates 221 increases to two or more, these pin slots 31 are arranged at certain intervals along the axial direction of the pins 3. This design allows the pins 3 to be locked with the locking member 1 in multiple positions, thereby enhancing the stability of the connection. At the same time, multiple retaining plates 221 are also arranged at corresponding intervals along the same direction as the pin slots 31. These retaining plates 221 can tightly engage with the pins 3 in the pin slots 31, further consolidating the connection between the quick-change box 20 and the drive table 10.

[0079] In contrast to the locking section 22, when the pin 3 slides to the release section 23, the locking plate 221 gradually disengages from the pin groove 31, causing the locking member 1 to disengage from the pin 3, thereby completing the separation of the quick-change box 20 from the drive table 10.

[0080] Optionally, see Figure 5 The card plate 221 is an arc-shaped strip, and the two ends of the card plate 221 adjacent to the release section 23 form an edge portion 2211. The thickness of the edge portion 2211 gradually decreases in the direction toward the release section 23.

[0081] In the above technical solution, the edge portion 2211 is the part that the pin groove 31 directly contacts during the locking and releasing processes.

[0082] During the locking process, when the pin 3 slides to the locking section 22, the edge portion 2211 contacts the pin groove 31. Since the thickness of the edge portion 2211 gradually decreases in the direction towards the release section 23, this structure allows the edge portion 2211 to gradually adapt to the shape of the pin groove 31 during contact, thus providing a guiding function. This guiding function helps ensure precise alignment between the pin 3 and the pin groove 31, improving the stability and reliability of the locking mechanism.

[0083] During the release process, as the pin 3 slides to the release section 23, the edge portion 2211 gradually moves away from the pin groove 31. Because the thickness of the edge portion 2211 gradually decreases, the resistance encountered by the retaining plate 221 when leaving the pin groove 31 gradually decreases, thus achieving smooth disengagement. This smooth disengagement not only reduces friction and wear during the release process but also improves the efficiency and service life of the quick-change mechanism 30.

[0084] According to some embodiments of this utility model, combined with Figure 5 and Figure 9 The surface of the edge portion 2211 facing the center of the movable groove 2 is a guide slope 2211a. The distance between the guide slope 2211a and the inner wall surface of the movable groove 2 gradually decreases in the direction towards the release section 23.

[0085] In the above technical solution, the surface of the edge portion 2211 of the locking plate 221 facing the center of the movable groove 2 is constructed as a guide slope 2211a. The guide slope 2211a is a gradually inclined surface, and the distance between it and the inner wall surface of the movable groove 2 gradually decreases in the direction towards the release section 23. This allows the edge portion 2211 to transition more smoothly when it contacts the pin groove 31, thereby reducing friction and wear, and helping to improve the smoothness of locking and releasing.

[0086] Specifically, during the locking process, when the pin 3 slides to the locking section 22, the guide slope 2211a of the edge portion 2211 contacts the corresponding part of the pin groove 31. Due to the design of the guide slope 2211a, the edge portion 2211 can gradually adapt to the shape of the pin groove 31, thereby ensuring precise alignment between the pin 3 and the pin groove 31. This precise alignment not only improves the stability of the locking but also reduces friction and wear caused by misalignment.

[0087] Conversely, during the release process, when the pin 3 slides to the release section 23, the guide slope 2211a of the edge portion 2211 gradually moves away from the pin groove 31. As the distance between the guide slope 2211a and the inner wall of the movable groove 2 gradually decreases, this design reduces the resistance encountered by the retaining plate 221 when it leaves the pin groove 31, resulting in a smoother disengagement. This smooth disengagement not only improves the efficiency of the quick-change mechanism 30 but also reduces heat and wear caused by friction, extending the service life of the quick-change mechanism 30.

[0088] In some alternative embodiments, combined with Figures 10-11 The quick-change mechanism 30 also includes a guide box 4, which has a guide cavity 41 extending in a first direction. The locking member 1 is slidably assembled in the guide cavity 41 in the first direction. The guide box 4 has a first mating port 42 facing the socket 21, and the pin 3 is inserted into the socket 21 through the first mating port 42.

[0089] By assembling the locking element 1 inside the guide cavity 41, the stability and accuracy of the locking element 1 during movement can be ensured, and the physical restriction of the guide cavity 41 can effectively prevent the locking element 1 from accidentally shifting or falling off.

[0090] To ensure that the pin 3 can accurately align with the socket 21 on the locking component 1, the guide box 4 has a first mating opening 42 directly opposite the socket 21. It is known that the position and size of this first mating opening 42 are adapted to the position and size of the socket 21. Specifically, the position and size of the first mating opening 42 can be exactly the same as the position and size of the socket 21. This way, when the pin 3 passes through the first mating opening 42, it can enter the socket 21 with the optimal posture and angle, thus achieving a secure locking connection. Alternatively, the size of the first mating opening 42 can be slightly larger than the size of the socket 21. This design provides some tolerance for the insertion of the pin 3. In actual operation, due to various factors (such as manufacturing tolerances, installation errors, etc.), the alignment between the pin 3 and the socket 21 may not always be perfect. Therefore, designing the size of the first mating opening 42 to be slightly larger than the size of the socket 21 allows the pin 3 to still smoothly enter the socket 21 through the first mating opening 42 even if there is a slight alignment error between the pin 3 and the socket 21.

[0091] Optionally, a chamfer can be provided at the corner of the first mating port 42 to guide the insertion process of the pin 3, thereby reducing installation errors and improving the installation efficiency of the quick-change box 20.

[0092] In some optional embodiments, the guide box 4 is disposed on the quick-change box 20, or the guide box 4 and the quick-change box 20 are integrally formed. The guide box 4 and the quick-change box 20 can be formed in one process; alternatively, the guide box 4 and the quick-change box 20 can be integrally cast. Of course, this invention is not limited to this; the guide box 4 can also be formed after the quick-change box 20 has been formed, in which case the guide box 4 and the quick-change box 20 can be formed after two processing steps. It is understood that regardless of the specific processing sequence of the guide box 4 and the quick-change box 20, as long as the guide box 4 and the quick-change box 20 are an integral structure after the overall processing is completed, it is acceptable.

[0093] Combination Figures 6-7 It can be seen that when the guide box 4 and the quick-change box 20 are integrally molded parts, the first mating port 42 is formed on the quick-change box 20.

[0094] According to some embodiments of the present invention, the quick-change mechanism 30 further includes: an elastic element 5 connected between the guide box 4 and the locking member 1, the elastic element 5 being used to push the locking member 1 to the locking position, and in the locking position, the locking section 22 of the movable groove 2 is aligned with the first mating port 42 so that the pin 3 is held on the locking section 22.

[0095] In the above technical solution, the elasticity of the elastic element 5 is used to provide a continuous and stable thrust to the locking element 1, so that it can automatically reset to the locked position.

[0096] In other words, when the quick-change box 20 is installed onto the drive platform 10, the locking member 1 can be pushed manually or otherwise to overcome the elastic force of the elastic element 5, allowing the locking member 1 to slide along the guide cavity 41 of the guide box 4 and push it until the release section 23 of the movable groove 2 is aligned with the first mating port 42. At this time, the pin 3 can be inserted into the release section 23 of the movable groove 2 through the first mating port 42. Then, the locking member 1 is released, and the elastic element 5 releases its elastic force to push the locking member 1 until the locking section 22 of the movable groove 2 is aligned with the first mating port 42. At this time, the pin 3 is locked in the locking section 22, thereby locking the quick-change box 20 onto the drive platform 10. Even if the drive platform 10 shakes during use, the elastic force of the elastic element 5 can keep the locking member 1 in the locked position with the pin 3 engaged, thus keeping the quick-change box 20 locked onto the drive platform 10.

[0097] Combination Figures 10-11 The elastic element 5 can be a spring, or it can be an elastic sheet or other elastic material. The elastic element 5 is connected between the guide box 4 and the locking member 1 to provide a thrust, so that the locking member 1 is held in the locked position.

[0098] Optionally, the elastic element 5 is located at one end of the guide cavity 41, and the other end of the guide cavity 41 forms an opening 43. The end of the locking member 1 extends out of the guide box 4 through the opening 43 so as to allow the locking member 1 to be manually pushed.

[0099] This design makes the movement of the locking element 1 more intuitive, and at the same time, it allows users to lock and release the quick-change box 20 through manual operation.

[0100] Specifically, combined Figure 10 In the initial state, the elastic element 5 is in a naturally extended state, and the locking member 1 is in the locked position. When the locking member 1 is in the locked position, the locking section 22 of the movable groove 2 is aligned with the first mating port 42, so that the pin 3 is held on the locking section 22.

[0101] The user manually pushes the locking member 1 located outside the opening 43 of the guide cavity 41, causing the locking member 1 to move in the first direction within the guide cavity 41 until the release section 23 on the movable groove 2 is aligned with the first mating port 42.

[0102] Next, combined Figure 11 Insert the pin 3 into the movable groove 2 from the first mating port 42 and into the release section 23.

[0103] Then, recombined Figure 10 After the user releases their hand, the locking part 1 automatically resets under the action of the elastic element 5, so that the locking section 22 on the movable groove 2 aligns with the first mating port 42, and the pin 3 enters the locking section 22 to complete the locking of the quick-change box 20.

[0104] Under the pushing force of the elastic element 5, the locking element 1 remains on the locking section 22, ensuring the firm fixation of the pin 3, thereby achieving stable locking of the quick-change box 20 and preventing accidental loosening or falling off during the operation.

[0105] When it is necessary to disassemble the quick-change box 20, the user manually pushes the locking member 1 located outside the opening 43 of the guide cavity 41, so that the locking member 1 moves within the guide cavity 41. Until the release section 23 on the movable groove 2 is aligned with the first mating port 42, at which point the pin 3 slides from the locking section 22 to the release section 23.

[0106] After pin 3 is released, the user can completely pull pin 3 out from socket 21, thereby releasing the quick-change box 20 from the drive platform 10. After removing the quick-change box 20, the user releases their hand, and the locking element 1 automatically resets under the action of the elastic element 5, returning to its initial state, ready for the next installation.

[0107] In some specific embodiments, such as Figure 12 As shown, the outer circumferential surface of the pin 3 is provided with a pin groove 31, and the inner circumferential surface of the movable groove 2 located in the locking section 22 is provided with a retaining plate 221.

[0108] The side of the locking plate 221 facing the release section 23 is the first side f1, and the side of the first mating opening 42 away from the release section 23 is the second side f2. When the pin 3 is located in the locking section 22, at least a portion of the locking plate 221 is engaged in the pin groove 31, and the elastic force F of the elastic element 5 pushes the locking member 1 toward the locked position, so that the pin 3 is clamped between the first side f1 and the second side f2.

[0109] Specifically, the width of the first mating opening 42 in the first direction is smaller than the width of the insertion opening 21 in the first direction. When the locking member 1 slides along the first direction to the release position, the first mating opening 42 can be directly aligned with the release section 23 of the insertion opening 21. When the locking member 1 slides along the first direction to the locking position, the first mating opening 42 can be directly aligned with the locking section 22 of the insertion opening 21. After the pin 3 is inserted into the release section 23 through the first mating opening 42, under the push of the elastic force F of the elastic element 5, the locking member 1 automatically slides to the locking position relative to the pin 3. And under the push of the elastic force F of the elastic element 5, the first side f1 of the clamping plate 221 is pushed towards the second side f2 of the first mating opening 42, thereby clamping the pin 3 between the first side f1 and the second side f2, and limiting the pin 3 relative to the locking member 1 in the first direction.

[0110] When the pin 3 is clamped between the first side f1 and the second side f2, the elastic force F of the elastic element 5 is balanced, thereby keeping the locking member 1 stationary relative to the guide box 1.

[0111] Furthermore, the inner circumferential surface of the locking section 22 away from the release section 23 is the third side surface f3, and the side of the clamping plate 221 away from the insertion port 21 is the fourth side surface f4. The third side surface f3, the fourth side surface f4, and the first side surface f1 are connected and form a stepped surface. When the pin 3 is located in the locking section 22, the pin 3 is in contact with at least one of the third side surface f3 and the first side surface f1 of the stepped surface. The diameter of the first mating port 42 can be slightly larger than the diameter of the pin 3, so that the pin 3 can pass through the first mating port 42. During the installation process, not only does the locking member 1 automatically slide to the locking position relative to the pin 3 under the push of the elastic force F of the elastic element 5, but the operator can also slightly push the quick-change box 20 in the opposite direction of the elastic force F of the elastic element 5, so that the pin 3 can be in contact with at least one of the third side surface f3 and the first side surface f1 of the stepped surface, thereby clamping the pin 3 in the first direction. The first direction is the downward tilt direction often used in interventional surgical instrument control systems, which can ensure the stability of the medical device during use.

[0112] At this time, refer to Figure 12 The first side f1 and the third side f3 form three continuous stepped surfaces extending upward along the axial direction of the pin 3. Even more continuous stepped surfaces can be formed by combining them with the inner side of the first mating opening 42. The stepped surfaces and the pin 3 generate directional friction, ensuring the clamping effect on the pin 3.

[0113] In some optional embodiments, the locking member 1 is further provided with a limiting part 11 for limiting the movement range of the locking member 1, and the limiting part 11 cooperates with the guide box 4.

[0114] The function of the limiting part 11 is to limit the range of movement of the locking part 1 within the guide box 4, ensuring that the locking part 1 always remains in the correct position during locking and unlocking, thereby achieving reliable locking and unlocking functions.

[0115] Therefore, the size and shape of the limiting part 11 need to be precisely matched with the corresponding part on the guide box 4. In this way, when the locking member 1 moves, the limiting part 11 can fit tightly against the corresponding position on the guide box 4, preventing the locking member 1 from exceeding the predetermined range of movement.

[0116] For example, the limiting part 11 can be a protrusion, groove, or other shaped structure on the locking member 1, which can fit tightly with corresponding parts (such as inner walls, flanges, or slots) on the guide box 4. When the locking member 1 moves within the guide box 4, the limiting part 11 contacts these parts of the guide box 4, thereby restricting further movement of the locking member 1.

[0117] Optionally, combined Figures 10-11The guide box 4 also includes a limiting plate 44 disposed in the guide cavity 41, and the limiting plate 44 is provided with a limiting hole 441. The limiting part 11 includes a limiting post 111 formed at the end of the locking member 1, and the limiting post 111 is fitted in the limiting hole 441; the limiting part 11 also includes a latching protrusion 113 disposed at the end of the limiting post 111.

[0118] In the above technical solution, the limiting plate 44 is a flat plate structure fixed in the guide cavity 41, and it is provided with limiting holes 441. The position and size of these limiting holes 441 can be precisely matched with the limiting part 11 on the locking member 1.

[0119] The limiting post 111 is a cylindrical or similar structure formed at the end of the locking member 1. Its size and shape match the limiting hole 441 on the limiting plate 44 inside the guide box 4, so that the limiting post 111 can be smoothly inserted into the limiting hole 441. When the locking member 1 moves in the guide cavity 41, the limiting post 111 will slide in the limiting hole 441, thereby limiting the range of movement of the locking member 1.

[0120] The locking protrusion 113 is a protrusion structure located at the end of the limiting post 111. Its main function is to enhance the tightness of the fit between the limiting post 111 and the limiting hole 441, and to prevent the locking member 1 from accidentally falling off or shaking during movement.

[0121] When the locking member 1 moves within the guide cavity 41, the limiting post 111 is located within the limiting hole 441 and slides therein. Simultaneously, the locking protrusion 113 fits tightly against the corresponding position in the limiting hole 441, ensuring that the locking member 1 does not exceed the predetermined range of movement. This engagement mechanism not only improves the stability and accuracy of the locking member 1 but also enhances the reliability and durability of the quick-change mechanism 30.

[0122] In some specific embodiments, the limiting posts 111 are two spaced-apart posts, located on the same side of the locking member 1. Each limiting post 111 has a latching protrusion 113 on the side furthest from each other. The latching protrusion 113 structure ensures that the locking member 1 fits against the edge of the limiting hole 441 of the limiting plate 44 inside the guide box 4.

[0123] It is worth noting that when the locking component 1 is initially installed, a slight external force is applied to the two limiting posts 111 of the locking component 1 in a direction toward each other, causing them to undergo slight elastic deformation. In this way, the distance between the two limiting posts 111 and the latching protrusions 113 on them will be reduced, which is sufficient to allow them to pass smoothly through the limiting holes 441 on the limiting plate 44 inside the guide box 4.

[0124] While maintaining a slight deformation, push the locking member 1 along the direction of the guide cavity 41 until the two limiting posts 111 completely pass through the limiting hole 441.

[0125] Once the limiting post 111 passes through the limiting hole 441, the previously applied external force can be released. At this time, due to the elastic restoring force of the limiting post 111, it will quickly return to its original shape. Thus, when the locking member 1 moves to the locking section 22, the latching protrusion 113 will fit tightly against the corresponding position of the limiting hole 441, achieving abutment with the limiting plate 44. In this way, the locking member 1 is firmly fixed in the guide box 4 and cannot be easily removed.

[0126] To facilitate the initial installation of the locking protrusion 113, the edge of the locking protrusion 113 is chamfered. This design allows the locking protrusion 113 to slide more smoothly into the limiting hole 441, reducing friction and resistance during the installation process, thereby improving installation efficiency, and also protecting the limiting hole 441 and the locking protrusion 113 from damage.

[0127] According to some embodiments of the present invention, alignment marks are provided on the drive stage 10 and the quick-change box 20.

[0128] Optionally, clearly visible alignment marks can be set at the designated position on the drive stage 10. These marks include, but are not limited to, lines, arrows, dots, or other easily identifiable graphics. This helps the operator quickly and accurately locate the insertion position of the pin 3.

[0129] Similarly, at the corresponding position on the quick-change box 20, alignment marks matching the alignment marks on the drive stage 10 are also provided. These marks include, but are not limited to, lines, arrows, dots, or other easily identifiable graphics.

[0130] Therefore, by setting alignment marks, users can quickly and accurately complete the assembly work without spending a lot of time on debugging and correction.

[0131] Moreover, the alignment marks make the assembly process more intuitive and easy to understand, so even users who are new to the quick-change mechanism 30 can easily get started.

[0132] According to some embodiments of this utility model, such as Figures 13-17As shown, the interventional surgery control system 100 also includes a motor drive mechanism 60 mounted on the drive stage 10. The motor drive mechanism 60 further includes: a mounting box 61, a transmission assembly 62, a drive motor 63, an output shaft 64, and an elastic element 65. The mounting box 61 has an assembly cavity 611. The transmission assembly 62 is located in the assembly cavity 611 and includes an input gear 621 and an output gear 622 for power connection. The output gear 622 has a first mating hole 6221 at its center, which is a non-circular hole. The drive motor 63 is mounted on the mounting box 61 and located outside the mounting box 10. The motor shaft 631 of the drive motor 63 is connected to the input gear 621 to transmit power. One end of the output shaft 64 is fitted into the first mating hole 6221, and the other end of the output shaft 64 is located outside the mounting box 61. The output shaft 64 is movable along its axial direction. The elastic element 65 connects the output shaft 64 and the output gear 622, and the elastic element 65 is used to push a portion of the output shaft 64 out of the mounting box 61.

[0133] In the above technical solution, the mounting box 61 is the main body of the entire mechanism. Optionally, the mounting box 61 is made of high-strength and highly durable materials. An assembly cavity 611 is provided inside the mounting box 61. The assembly cavity 611 provides a stable working environment for the transmission assembly 62 and the drive motor 63, and protects the internal parts from interference from the external environment.

[0134] The mounting box 61 not only serves as a support structure, but can also be equipped with mounting slots, positioning holes, etc., to ensure the accurate installation and positioning of multiple internal components.

[0135] The transmission assembly 62 includes an input gear 621 and an output gear 622 for power connection. The input gear 621 is directly connected to the motor shaft 31 of the drive motor 63, thus seamlessly receiving the driving force from the drive motor 63. The output gear 622 is connected to the output shaft 64 through its central first mating hole 6221, transmitting power to the output shaft 64, achieving direct and efficient power transmission to the output shaft 64. This configuration effectively reduces the need for additional connecting elements such as couplings, simplifying the structure of the transmission system and reducing overall weight. The motor drive mechanism 60 occupies a smaller volume during surgery, providing the surgeon with a wider surgical field of vision, which helps improve the precision and safety of the surgery.

[0136] The first mating hole 6221 is designed as a non-circular hole. This non-circular hole design ensures the alignment between the output shaft 64 and the output gear 622, preventing relative rotation between them.

[0137] Alternatively, the first mating hole 6221 can be designed as a triangle, or it can be designed as a quadrilateral or other polygon.

[0138] In some optional embodiments, when the first mating hole 6221 is not a circular hole, a chamfer is provided at the corner. By providing a chamfer, a bevel or rounded corner is formed, which can eliminate the sharp parts at the corner, thereby dispersing stress and reducing the potential damage to the workpiece due to stress concentration. On the other hand, the corner after the chamfer is provided is smoother, which is conducive to the smooth insertion and positioning of the output shaft 64, reducing assembly difficulty and time, and improving assembly efficiency.

[0139] The drive motor 63 is mounted on the mounting box 61. Optionally, the drive motor 63 can be fixed by means of a motor mounting plate or by direct mounting on the mounting box 61. The motor shaft 31 of the drive motor 63 is connected to the input gear 621 via a power connection. Optionally, the motor shaft 31 and the input gear 621 are connected by means of a keyway, pins, etc.

[0140] Combination Figures 13-14 The drive motor 63 is mounted on the side of the mounting box 61, and the other components are mainly mounted in the assembly cavity 611 of the mounting box 61. The motor drive mechanism 60 is set as a whole by relying on the mounting box 61. When the interventional surgery control system requires two, three or more motor drive mechanisms, it is convenient to install the motor drive mechanism in the interventional surgery control system. At the same time, it helps to ensure the consistency of the matching between the corresponding multiple roller assemblies in the mounting box 61 and the drive shaft, so as to achieve fast and stable installation.

[0141] One end of the output shaft 64 is fitted into the first mating hole 6221 of the output gear 622, while the other end extends out of the mounting box 61 for flexible connection with external devices. Optionally, the access end of the external device can be a connection hole, etc.

[0142] The cross-section of the output shaft 64 is designed to match the size and shape of the first mating hole 6221.

[0143] The elastic element 65 connects the output shaft 64 and the output gear 622. The elastic element 65 is used to push a portion of the output shaft 64 out of the mounting box 61.

[0144] The elastic element 65 connects between the output shaft 64 and the output gear 622, or acts directly on the output shaft 64. The elastic element 65 applies a continuous outward pushing force to the output shaft 64. Thus, when the output shaft 64 is in an unconnected state, it is subjected to this outward force and tends to extend out of the mounting box 61. Once it encounters a connection with an external device, the output shaft 64 can smoothly and automatically extend outward along its axial direction into the connection of the external device, thereby completing the connection and establishing effective power transmission.

[0145] Specifically, the output shaft 64 is movable along its axial direction. When the shape and size of the end of the output shaft 64 match the access end of an external device, it will automatically extend outward along the axial direction and smoothly insert into the external device, thereby realizing power transmission. Conversely, if the cross-sectional shape or size of the output shaft 64 does not match the access end, it will remain in place, avoiding unnecessary mechanical interference.

[0146] More specifically, when the motor drive mechanism 60 is installed on the drive platform 10, but the output shaft 64 does not match the angle of the drive shaft, the output shaft 64 cannot connect to the drive shaft. The output shaft 64 is pressed into the mounting box 61, thus pressing the elastic element 65. After the drive motor 63 starts, it drives the output gear 622 to rotate via the input gear 621, thereby driving the output shaft 64 to rotate. When the output shaft 64 rotates to an angle that matches the drive shaft angle, the output shaft 64 is pushed towards the drive shaft by the elastic force of the elastic element 65, thus connecting the output shaft 64 to the drive shaft and achieving power transmission from the output shaft 64 to the drive shaft. Moreover, during the transmission process, the elastic force of the elastic element 65 ensures a secure connection between the output shaft 64 and the drive shaft. This design allows the operator to adjust the angle of the output shaft 64 or the drive shaft manually when the motor drive mechanism 60 is connected to the drive shaft, making equipment replacement faster.

[0147] Therefore, this motor-driven mechanism 60, with its output shaft 64, can automatically extend and connect when it encounters a matching external device, eliminating the need for manual adjustment or additional auxiliary devices. This improves the accuracy and efficiency of the connection, correspondingly reducing the operational steps and complexity for users when replacing or connecting equipment, and lowering the skill requirements for operators. Furthermore, this automated connection process improves work efficiency, especially in scenarios requiring frequent replacement of external devices.

[0148] The following is for reference. Figure 1 - Figure 11 The interventional surgical control system 100 according to an embodiment of the present invention is described in detail with reference to a specific example. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0149] Reference Figure 1 The interventional surgery control system 100 includes a drive stage 10, a quick-change box 20, and a quick-change mechanism 30, wherein the quick-change box 20 is detachably connected to the drive stage 10 via the quick-change mechanism 30.

[0150] Reference Figure 1 , Figure 10 The quick-change mechanism 30 includes: a locking element 1, a pin 3, a guide box 4, and an elastic element 5.

[0151] Reference Figures 10-11The guide box 4 is located on the quick-change box 20. The guide box 4 has a guide cavity 41 extending in the first direction. The locking member 1 is slidably assembled in the guide cavity 41 in the first direction.

[0152] Reference Figures 2-4 The locking member 1 is provided with a movable groove 2, and a socket 21 is formed on one side of the movable groove 2.

[0153] Reference Figures 6-7 The quick-change box 20 is provided with a first mating port 42 facing the socket 21. The pin 3 is inserted into the socket 21 through the first mating port 42. Subsequently, the pin 3 extends further from the socket 21 into the movable groove 2 and can slide in the movable groove 2 along the first direction.

[0154] The elastic element 5 is connected between the guide box 4 and the locking member 1, and is located at one end of the guide cavity 41. The elastic element 5 is used to push the locking member 1 to the locked position, and in the locked position, the locking section 22 of the movable groove 2 is aligned with the first mating port 42 so that the pin 3 is held on the locking section 22.

[0155] Reference Figures 10-11 The other end of the guide cavity 41 forms an opening 43, and the end of the locking member 1 extends out of the guide box 4 through the opening 43 so that the locking member 1 can be manually pushed.

[0156] Reference Figures 10-11 The locking member 1 is also provided with a limiting part 11. The limiting part 11 is used to limit the movement range of the locking member 1, and the limiting part 11 cooperates with the guide box 4.

[0157] The guide box 4 also includes a limiting plate 44 disposed in the guide cavity 41, and the limiting plate 44 is provided with a limiting hole 441.

[0158] The limiting part 11 includes a limiting post 111 formed at the end of the locking member 1 and a latching protrusion 113 provided at the end of the limiting post 111. The limiting post 111 is fitted into the limiting hole 441.

[0159] Reference Figures 2-5 The active slot 2 includes a locking section 22 and a releasing section 23 arranged along the first direction.

[0160] When pin 3 slides along the first direction to the locking section 22, pin 3 is locked at the locking section 22, so that quick-change box 20 is locked on the drive table 10.
