Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to a registration and disassembly device between two devices and surgical instruments, and more particularly to a trolley registration and disassembly device based on the side rail of an operating table. Background Technology
[0002] Currently, most surgical carts and operating tables require registration by moving the cart to a fixed area, locking it in place, and then connecting it via a fixed connection structure. Registration is then achieved using methods such as optical target identification, structured light scanning, or binocular camera-based identification of the cart target and the patient target on the operating table. If the registration error is large, such as a significant height difference between the cart and the operating table, the patient or cart position needs to be readjusted. However, during this readjustment, because the surgical cart and operating table are fixedly connected, the height cannot be directly adjusted. The connection structure must first be unlocked, the height adjusted, and then the connection structure reconnected and locked, making the registration process cumbersome, time-consuming, and costly.

[0021] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.
[0022] This utility model provides a registration and disassembly device between two devices. In a preferred embodiment, the registration and disassembly device between the two devices is a registration and disassembly device for an operating table and an operating trolley. The registration and disassembly device between the two devices includes a first connecting member 21 and a second connecting member 22 that are detachably connected. The second connecting member 22 includes a locking block 5 and a registration shaft 8. The registration shaft 8 is detachably connected to the locking block 5. The locking block 5 is mounted on the operating trolley 2. Specifically, one end of the locking block 5 is fixedly connected to the operating trolley by a bolt, and the other end has a round hole for inserting the registration shaft. A robotic arm 3 is mounted on the operating trolley 2.
[0023] The first connecting member 21 includes a mounting base 4, a left rotating block 6, a right rotating block 7, and a shaft structure. The mounting base 4 is mounted on the operating table 1. In a preferred embodiment, the mounting base 4 is mounted on the side rail 29 of the operating table 1. The left rotating block 6 and the right rotating block 7 are rotatably mounted on the mounting base 4. Specifically, the mounting base 4 is provided with two concave openings. The left rotating block 6 and the right rotating block 7 are both provided with oblong holes 24. The left rotating block 6 and the right rotating block 7 are rotatably mounted in the concave openings through the cooperation of the shaft structure with the oblong holes 24. That is, the shaft structure can translate along the length direction of the oblong holes. In other words, the movement of the left rotating block 6 and the right rotating block 7 relative to the mounting base 4 includes not only rotational movement but also translational freedom along the length direction of the oblong holes 24 due to the oblong holes 24. The left rotating block 6 and the right rotating block 7 are provided with an opening structure 25, and the first connecting member 21 is detachably connected to the registration shaft 8 through the opening structure 25.
[0024] The first connecting member 21 also includes a locking knob 13 and a lever 14; the lever 14 passes through the locking knob 13, and the mounting base 4 is mounted on the operating table 1 via the locking knob 13. The lever 14 can lock the locking knob 13 to achieve locking of the mounting base 4 and the locking knob 13.
[0025] The shaft structure includes a pin shaft 11 and a nut 12; specifically, the nut 12 is an M10 anti-loosening nut. The left rotating block 6 and the right rotating block 7 are rotatably connected to the mounting base 4 via the pin shaft 11 and the nut 12. That is, the left rotating block 6 and the right rotating block 7 can rotate around the pin shaft 11.
[0026] The first connector 21 also includes two step positioning pins 9. The mounting base 4 is provided with two step positioning holes 23. The left rotating block 6 and the right rotating block 7 are both provided with arc-shaped grooves 28. The two step positioning pins 9 are installed in the step positioning holes 23, and the ends of the two step positioning pins 9 are respectively inserted into the two arc-shaped grooves 28 to limit the rotation angle of the left rotating block 6 and the right rotating block 7.
[0027] The bottom diameter D of the opening structure 25 is matched with the diameter of the registration axis 8. The bottom diameter D is equal to or slightly larger than the diameter of the registration axis 8, and the diameter of the registration axis 8 must meet the strength required for the trolley registration collision.
[0028] In a preferred embodiment, the inlet width H of the opening structure 25 is greater than the bottom diameter D of the opening structure 25, and the opening angle of the opening structure 25 can be from 15° to 30°, preferably 20°. This opening angle limits the height adjustment error of the operating table; the larger the opening angle, the lower the requirement for the height adjustment accuracy of the operating table before registration. In another preferred embodiment, the inlet width H of the opening structure 25 is smaller than the bottom diameter D of the opening structure 25. This arrangement allows for a more secure assembly of the registration shaft 8 with the left rotating block 6 and the right rotating block 7. After the registration shaft 8 is assembled with the left rotating block 6 and the right rotating block 7, the registration shaft 8 and the inlet of the opening structure 25 achieve an interference fit, making it difficult for the registration shaft 8 to detach from the assembly direction of the registration shaft 8 (i.e., the direction of the inlet of the opening structure 25), but only to be pulled away from the left rotating block 6 and the right rotating block 7 along the axial direction of the registration shaft 8. A groove structure 26 is provided in the middle part (preferably the central section) of the registration shaft 8.
[0029] The locking block 5 is provided with a round hole for inserting a registration shaft; the second connecting member 22 also includes a spring 17, a limiting block 15, a positioning pin 16 and a toggle button 10; the locking block 5 is provided with a receiving groove 27; the spring 17 and the limiting block 15 are both installed in the receiving groove 27, and the two ends of the spring 17 abut against the limiting block 15 and the locking block 5 respectively; The positioning pin 16 passes through the limiting block 15, and both ends of the positioning pin 16 are connected to the dial 10. The dial 10 is located on the surface of the locking block 5 and can slide along the surface of the locking block 5. When the dial 10 slides, the dial 10 can drive the limiting block 15 to slide in the receiving groove 27 through the positioning pin 16 and compress or release the spring 17.
[0030] The groove structure 26 can match the limiting block 15. After the registration shaft 8 is inserted into the circular hole of the locking block 5, it pushes the limiting block 15 to compress the spring 17 until the limiting block 15 is located at the groove structure 26. The spring 17 automatically rebounds, and the limiting block 15 is inserted into the groove structure 26, completing the locking. Specifically, in a preferred embodiment, the limiting block 15 is a trapezoidal structure. After the registration shaft 8 is inserted, it contacts the inclined surface of the limiting block 15, the spring is compressed, and the limiting block 15 moves inward along the axis of the spring 17 until it contacts the groove structure 26 in the middle of the registration shaft 8. The limiting block 15 automatically rebounds and locks into the groove structure 26, achieving automatic rebound.
[0031] The registration and disassembly device between the two devices also includes an LED visible light source 18, which is mounted on the operating table 1 and illuminates the ground to show the reference outline of the operating trolley 2. Specifically, the LED visible light source 18 is powered by a battery and can form a reference outline in a target area on the ground. After the trolley is pushed into the outline and the initial position relative to the operating table is completed, the above-mentioned mating structure registration is performed.
[0032] The working process of this utility model is as follows: The operation of aligning the surgical cart 2 with the operating table (patient) is simple. The operator only needs to push the surgical cart 2 to engage the alignment shaft 8 with the left rotating block 6 and the right rotating block 7 respectively, thus locking the first connecting piece 21 and the second connecting piece 22, achieving relative alignment and marking. Opening the floor lock switch on the surgical cart 2 allows the cart to rise, and the left rotating block 6 and the right rotating block 7 rotate counterclockwise under the influence of the alignment shaft 8. When it is necessary to disconnect the surgical cart 2 from the operating table 1, pushing the toggle switch 10 unlocks the limit block 15 from the alignment shaft 8, allowing the alignment shaft 8 to be pulled out, releasing the connection between the surgical cart 2 and the operating table 1, thus completing the disassembly of the surgical cart 2 from the operating table 1.
[0033] In this invention, both the left rotating block 6 and the right rotating block 7 are rotatably mounted on the mounting base 4, allowing them to rotate relative to the mounting base 4. Furthermore, due to the design of the oblong hole 24, the left and right rotating blocks 6 and 7, in addition to rotational movement, also possess the freedom of translation along the length of the oblong hole 24. In other words, the left and right rotating blocks 6 and 7 are rotatably mounted on the mounting base 4 through the oblong hole, providing a certain degree of height adjustment between the locking block 5 and the mounting base 4. Even if there are height errors between the trolley and the operating table, there is no need to unlock the connection structure (i.e., the registration and disassembly device); the height of the trolley or operating table can be adjusted directly. Therefore, the registration process is simplified, reducing time and operating costs.
[0034] In addition, this utility model solves the problem of interference in the connection structure caused by the insertion and locking structure of the registration shaft 8 and the locking block at the trolley end, which requires the translation of the operating table during some surgical procedures such as CT, MRI, and DSA. After registration, the rotating shaft can be pulled out by pushing the button to achieve quick disassembly. During the process of disconnecting the operating table from the operating trolley, the relative position of the trolley and the operating table can be maintained. When reconnection is required later, the movement distance can be compensated into the registration software.
[0035] This invention also provides a way to improve the registration accuracy between the surgical cart and the operating table. For example, by designing an LED visible light source, the irradiated area allows for coarse registration adjustment of the cart's position relative to the operating table. The operator can move the cart to a fixed area based on the visible light, providing a prerequisite for subsequent precise registration and solving the problem of repeated cart position adjustments due to excessive distance between the surgical cart and the operating table.
