Description
Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to an orthopedic positioning and punching device. Background Art
[0002] In orthopedic surgery, precise positioning of the perforation site is essential to ensure that implants such as screws and plates are properly fixed to the bone. Traditional manual positioning methods rely on the surgeon's experience and skill, resulting in significant errors. Modern orthopedic positioning and perforation devices often integrate high-precision navigation systems or robotic arms to provide more accurate positioning services.
[0003] Existing drilling devices typically use a drill and a drill bit to drill holes in bone surfaces. While these devices are simple in structure and easy to operate, they suffer from several drawbacks in practical applications. Specifically, these devices lack effective guidance for the drilling path, which can lead to inaccurate drilling due to the drill bit's movement.
[0004] To sum up, how to solve the problem that the devices in the existing technology lack effective guidance of the drilling path, which causes the drill bit to shake during the drilling process and make the drilling inaccurate, has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose an orthopedic positioning drilling device. Summary of the Invention
[0005] In order to solve the above problems, the present invention provides an orthopedic positioning and punching device, which guides the drilling by auxiliary positioning at multiple angles through a positioning rod, and associates the spatial position of the shock-absorbing component with the spatial posture of the positioning rod, so that the shock-absorbing force can automatically match the current positioning angle, providing moderate rigid support while ensuring the accuracy of positioning and punching.
[0006] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an orthopedic positioning punching device includes a base plate, a positioning rod is ball-jointed on the base plate, and a through hole is opened in the positioning rod that penetrates the base plate; an adjustment component is provided on the base plate for adjusting the angle of the positioning rod.
[0007] The adjustment assembly includes a first rotating rod and a second rotating rod in a semicircular shape, which are perpendicular to each other; the second rotating rod is located above the first rotating rod, and both the first rotating rod and the second rotating rod are provided with a sliding groove for the positioning rod to slide.
[0008] The bottom plate is provided with a first rotating assembly and a second rotating assembly for driving the first rotating rod and the second rotating rod to rotate.
[0009] A shock absorbing assembly for providing buffering for the positioning rod is also provided on the bottom plate; the first rotating assembly and the second rotating assembly are respectively used to drive the shock absorbing assembly to move to provide buffering for the positioning rod.
[0010] The outer wall of the bottom plate is also provided with a conveying assembly for conveying disinfectant, and the first rotating assembly and the second rotating assembly are respectively used to drive the conveying assembly to operate for disinfection.
[0011] The technical principles of the above solution are as follows:
[0012] The first and second rotating assemblies respectively drive the rotation of the first and second rotating rods. Since the first and second rotating rods are perpendicular to each other and each has a slot for the positioning rod to rotate, the first and second rotating rods can drive the positioning rod to rotate when the first and second rotating rods rotate, thereby rotating the positioning rod to a specified position, and using the positioning rod to perform orthopedic drilling positioning. When the first and second rotating assemblies are in operation, they can simultaneously drive the shock absorbing assembly to move to a specified position to generate a buffering force on the positioning rod; and can also simultaneously drive the delivery assembly to deliver disinfectant for disinfection, thereby satisfying the disinfection requirements before and after use of the device.
[0013] The above scheme has the following beneficial effects:
[0014] 1. This invention combines angle adjustment, shock absorption, and disinfection and sterilization functions through a mechanical linkage design. As the first and second rotating rods rotate, the semicircular structure guides the positioning rod for auxiliary positioning at multiple angles. Furthermore, as the first and second rotating rods rotate and position themselves, the damping assembly automatically locks to reduce vibration by synchronously driving the displacement of the damping assembly and the start and stop of the disinfection assembly. Disinfection fluid delivery aligns with the drilled channel, thereby achieving disinfection and sterilization.
[0015] 2. This invention links the spatial position of the damping assembly with the spatial posture of the positioning rod. When the first and second rotating rods drive the positioning rod to change the drilling angle, the rotational angle of the first and second rotating rods is converted into the radial displacement of the damping assembly. This mechanical feedback mechanism automatically adjusts the damping force to the current positioning angle, providing moderate rigidity while ensuring accurate positioning and drilling.
[0016] 3. The present invention is linked to the first rotating rod and the second rotating rod through the conveying component. When adjusting the angle of the positioning rod, the conveying component is used to disinfect the positioning position after the positioning adjustment is completed, thereby reducing the risk of secondary infection during the orthopedic positioning drilling process, thereby improving the reliability of the equipment.
[0017] Furthermore, the first rotating assembly includes a controller and a first driving member, the controller is used to control the first driving member to rotate; the first driving member is fixedly connected to the outer wall of the base plate, and the output shaft of the first driving member passes through the base plate and is fixedly connected to the first rotating rod.
[0018] Beneficial Effects: The controller regulates the rotation of the first driving member, ensuring high repeatability of the positioning adjustment of the first rotating rod. The output shaft is fixedly connected to the first rotating rod to achieve torque transmission, thereby using the rotation of the first driving member to drive the first rotating rod to rotate, allowing the first rotating rod to adjust the angle of the positioning rod to meet the adjustment requirements of different drilling directions.
[0019] Furthermore, the second rotating assembly includes a second driving member, and the controller is used to control the second driving member to rotate; the second driving member is fixedly connected to the outer wall of the base plate, and the output shaft of the second driving member passes through the base plate and is fixedly connected to the second rotating rod.
[0020] Beneficial Effects: The controller controls the opening and closing of the second drive element to independently drive the rotation of the second rotating rod. The second rotating rod and the first rotating rod form orthogonal dual-axis adjustment, achieving precise multi-degree-of-freedom positioning of the positioning rod in three-dimensional space, ensuring transmission efficiency and stability. Furthermore, the angle adjustment of the second rotating rod complements and synergizes with the first rotating rod, expanding the device's adaptability to complex bone surfaces, thereby improving the smoothness and reliability of overall operation.
[0021] Furthermore, the shock absorbing assembly includes several shock absorbers, the first rotating rod and the second rotating rod both extend to the outer wall of the base plate and are fixedly connected to the main gear; the main gears are symmetrically meshed with sub-gears, and the sub-gears are coaxially threaded with screw rods; the ends of the screw rods close to the sub-gears pass through the base plate and are fixedly connected to the adjacent shock absorbers, and the screw rod threads on adjacent sub-gears are in opposite directions.
[0022] The outer wall of the bottom plate is also provided with a limiting component for providing a linear motion trajectory for the screw rod.
[0023] Beneficial Effects: The main gear meshes symmetrically with the secondary gears, and the screw threads on the secondary gears run in opposite directions. When the main gear rotates, the screws on both sides move synchronously in opposite directions, transferring the shock absorbers to contact the bottom of the positioning rod. A limiter assembly constrains the linear motion trajectory of the screws, ensuring that the shock absorber displacement direction aligns with the force axis. This linkage mechanism converts rotational motion into linear movement, allowing the damping force to adaptively adjust with the angles of the first and second rotating rods, while balancing the requirements of rigid support and flexible vibration absorption, thereby enhancing stability during orthopedic drilling.
[0024] Furthermore, the limit assembly includes several limit plates and limit rods. The limit plates are all located on the outside of the base plate, and the limit rods are all located on both sides of the vertical direction of the sub-gear; the two ends of the limit rods are respectively fixedly connected to the outer wall of the base plate and the limit plates, and the end of the screw rod away from the shock absorber is fixedly connected to the sliding plate; the sliding plates are all slidably matched with the limit rods adjacent to them.
[0025] Beneficial Effects: The linear guidance of the sliding plate and the limit rod constrains the screw's trajectory, further reducing the risk of lateral deviation and torsion. The connection between the limit rod and the base plate forms a stable guide frame, reducing friction loss and vibration noise during screw movement, and improving the shock absorber's response speed and consistency.
[0026] Furthermore, the conveying assembly includes several piston cylinders and piston plates, the piston plates are all slidably fitted with the inner walls of the piston cylinders, and the piston cylinders are all fixedly connected to the outer wall of the base plate; the side of the piston cylinder away from the base plate is connected to an input pipe and an output pipe, and the connections between the input pipe and the output pipe and the piston cylinder are all connected to a one-way valve; the end of the input pipe away from the piston cylinder is connected to a storage tank for storing disinfectant, and the end of the output pipe away from the piston cylinder is connected to the through hole.
[0027] A transmission assembly for driving the piston plate to move is provided on the bottom plate.
[0028] Beneficial Effects: The piston plate and transmission assembly work together to deliver a quantitative amount of disinfectant. A one-way valve ensures unidirectional flow, creating a circulation path from the storage tank to the through-hole. The transmission assembly synchronizes the reciprocating motion of the piston plate with positioning adjustments, simplifying manual procedures and improving surgical efficiency.
[0029] Furthermore, the transmission assembly includes several threaded rods and nut seats, and the threaded rods are all coaxially fixedly connected to the main gear adjacent to them; the ends of the threaded rods away from the main gear all penetrate the interior of the piston cylinder and are threadedly engaged with the nut seats adjacent to them, and the nut seats are all fixedly connected to the piston plates adjacent to them.
[0030] Beneficial Effects: Through the coaxial connection between the threaded rod and the main gear, the main gear's rotational motion is converted into linear displacement of the piston plate, achieving mechanical linkage between disinfectant delivery and drilling angle adjustment. This design eliminates the need for a separate drive source and leverages the power redundancy of the main gear to synchronize sterilant delivery. The reciprocating motion of the piston plate creates a direct current through a one-way valve, directing disinfectant flow to the disinfection area. The closed flow channel design completely isolates external contaminants, creating a sterile environment throughout the entire process.
[0031] Furthermore, it also includes a punching robot arm for punching, and the controller is used to control the operation of the punching robot arm.
[0032] Beneficial Effects: The integrated drilling robot automates orthopedic positioning drilling, with the drilling path coordinated with the positioning rod angle, reducing manual operation errors. Automated control synchronizes drilling depth, sterilant coverage, and shock absorption, improving surgical safety and efficiency.
[0033] Furthermore, a camera is fixedly connected to the punching robot arm, and the controller is used to receive and store image information sent by the camera. A plurality of angle sensors are also fixedly connected to the punching robot arm, and the controller is used to receive and store angle information sent by the angle sensors.
[0034] Beneficial Effects: A camera captures images of the drilling area in real time and transmits them to the controller, providing the doctor with a high-definition visual operating interface to assist in locating bone surface anatomical landmarks. The image storage function fully records the surgical process, facilitating postoperative effect evaluation and operation traceability. Mechanical collaborative control enhances operational intuitiveness, thereby reducing the difficulty of surgery in complex cases. An angle sensor monitors the movement posture of the drilling robot arm in real time, providing angle feedback to the device to ensure that the drilling path is consistent with the preset trajectory. When an abnormal angle deviation is detected, correction or emergency braking is automatically triggered, thereby improving surgical safety and operational repeatability.
[0035] Furthermore, a straight cylinder for storing disinfectant is fixedly connected to the top of the positioning rod, and a conveying plate is slidably fitted on the inner wall of the straight cylinder; a vertical rod is fixedly connected to the top of the conveying plate, and the top of the vertical rod extends to the outside of the straight cylinder and contacts the punching robot arm, and a conveying pipe is connected to the bottom of the straight cylinder, and the end of the conveying pipe away from the straight cylinder is connected to the through hole.
[0036] Beneficial effect: During the punching process, the punching robot arm will slowly advance toward the positioning rod; and by utilizing the design of the vertical rod, the punching robot arm can push the vertical rod when punching, so that the vertical rod can push the conveying plate to transport the disinfectant inside the straight cylinder to the through hole, thereby realizing synchronous disinfection of the punching position during the punching process, further improving the sterility of the device operation.

DETAILED DESCRIPTION
[0047] The following is further described in detail through specific implementation methods:
[0048] Embodiment 1:
[0049] As attached Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown: an orthopedic positioning punching device, including a base plate 1, a positioning rod 2 is ball-jointed on the base plate 1, and a through hole is opened in the positioning rod 2 and penetrates the base plate 1; an adjustment component for adjusting the angle of the positioning rod 2 is provided on the base plate 1.
[0050] The adjustment assembly includes a semicircular first rotating rod 3 and a second rotating rod 4, which are perpendicular to each other. The second rotating rod 4 is located above the first rotating rod 3. Both the first rotating rod 3 and the second rotating rod 4 have slots for the positioning rod 2 to slide. The slots provide a limit for the positioning rod 2, ensuring stable movement. In this embodiment, the first rotating rod 3 and the second rotating rod 4 slide in conjunction with each other.
[0051] The base plate 1 is provided with a first rotating assembly and a second rotating assembly for driving the first rotating rod 3 and the second rotating rod 4 to rotate.
[0052] The first rotating assembly includes a controller and a first driving member. In this embodiment, the first driving member is a first motor 5, and the controller is used to control the rotation of the first motor 5; the first motor 5 is fixedly connected to the outer wall of the base plate 1 by screws, and the output shaft of the first motor 5 passes through the base plate 1 and is fixedly engaged with the first rotating rod 3.
[0053] The second rotating assembly includes a second driving member. In this embodiment, the second driving member is a second motor 6. The controller is used to control the rotation of the second motor 6. The second motor 6 is fixedly connected to the outer wall of the base plate 1 with screws, and the output shaft of the second motor 6 passes through the base plate 1 and is fixedly engaged with the second rotating rod 4. In this embodiment, the output shaft of the first motor 5 and the output shaft of the second motor 6 are both rotationally coordinated with the base plate 1.
[0054] Specific, combined Figure 2 and Figure 3 As shown, because the output shaft of the first motor 5 extends through the base plate 1 and is fixedly engaged with the first rotating rod 3, and the output shaft of the second motor 6 extends through the base plate 1 and is fixedly engaged with the second rotating rod 4, when the first and second motors 5 and 6 are activated, their output shafts respectively drive the first rotating rod 3 (in the X-axis direction) and the second rotating rod 4 (in the Y-axis direction) to rotate about the center of the spherical joint of the base plate 1. When the first rotating rod 3 rotates, the guide groove guides the positioning rod 2 in the XZ plane; when the second rotating rod 4 rotates, the guide groove guides the positioning rod 2 in the YZ plane. This design allows the positioning rod 2 to be adjusted to accommodate orthopedic positioning holes of varying orientations and angles, thereby enabling multi-directional drilling within a single plane. This, in turn, reduces the need to adjust the position of the limb being drilled, thereby minimizing secondary injuries caused by movement or adjustment of the limb.
[0055] A shock absorbing assembly for providing buffering for the positioning rod 2 is also provided on the bottom plate 1 ; the first rotating assembly and the second rotating assembly are respectively used to drive the shock absorbing assembly to move to provide buffering for the positioning rod 2 .
[0056] Combined with attachment Figure 4 and attached Figure 5 As shown, the shock absorbing assembly includes several shock absorbers 7, the first rotating rod 3 and the second rotating rod 4 are extended to the outer wall of the base plate 1 and fixedly connected with the main gear 8; the main gears 8 are symmetrically meshed with the sub-gears 9, and the sub-gears 9 are coaxially threaded with screw rods 10; the ends of the screw rods 10 close to the sub-gears 9 pass through the base plate 1 and are fixedly connected with the adjacent shock absorbers 7 with screws, and the thread directions of the screw rods 10 on adjacent sub-gears 9 are opposite.
[0057] The outer wall of the base plate 1 is also provided with a limit assembly for providing a linear motion trajectory for the screw rod 10. The limit assembly includes several limit plates 11 and limit rods 12. The limit plates 11 are all located outside the base plate 1, and the limit rods 12 are located on both sides of the pinion 9 in the vertical direction. The two ends of the limit rods 12 are fixedly screwed to the outer wall of the base plate 1 and the limit plates 11 respectively. The end of the screw rod 10 away from the shock absorber 7 is fixedly screwed to a sliding plate 13. The sliding plates 13 each slide in conjunction with the adjacent limit rod 12.
[0058] Specifically, when the first rotating rod 3 or the second rotating rod 4 rotates, the main gear 8 extending to the outer wall of the bottom plate 1 rotates synchronously. The two sets of sub-gears 9 symmetrically meshed on both sides of the main gear 8 also rotate synchronously. For example, when the main gear 8 rotates clockwise, the sub-gears 9 on both sides rotate counterclockwise. When the sub-gears 9 rotate, the screw rods 10 are driven to move by the threads. Since the screw rods 10 on the sub-gears 9 meshing with the same main gear 8 have opposite thread directions, the reverse thread design is used to make the screw rods 10 on both sides move in opposite directions, forming a symmetrical motion force. Figure 5 For example, when the main gear 8 rotates, it synchronously drives the sub-gears 9 on both sides to rotate, the left screw rod 10 moves toward the right side of the base plate 1, and the right screw rod 10 moves toward the left side of the base plate 1. In this embodiment, when the screw rods 10 on both sides are extended, they are opposite to the angle adjustment direction of the positioning rod 2, which will not affect the angle adjustment of the positioning rod 2, so that the positioning rod 2 can be adjusted stably.
[0059] Combine Figure 7 As shown, one end of the screw rod 10 is fixed to the shock absorber 7 by a screw, and the sliding plate 13 at the other end of the screw rod 10 slides along the limit rod 12, so that the screw rod 10 maintains linear movement. When the screw rod 10 moves toward the inside of the base plate 1, the shock absorber 7 contacts the ball joint connection between the positioning rod 2 and the base plate 1, and the shock absorber 7 is gradually compressed, thereby increasing the damping force and reducing the vibration amplitude of the positioning rod 2; when the screw rod 10 moves toward the outside of the base plate 1, the shock absorber 7 moves away from the ball joint connection between the positioning rod 2 and the base plate 1, and the shock absorber 7 is gradually released and retracted; in this embodiment, the greater the rotation angle of the positioning rod 2, the stronger the damping effect of the shock absorber 7.
[0060] The outer wall of the bottom plate 1 is also provided with a conveying assembly for conveying disinfectant, and the first rotating assembly and the second rotating assembly are respectively used to drive the conveying assembly to operate for disinfection.
[0061] The conveying assembly includes several piston cylinders 14 and piston plates 15. The piston plates 15 are all slidably fitted with the inner walls of the piston cylinders 14, and the piston cylinders 14 are all fixedly connected to the outer wall of the base plate 1 with screws; the side of the piston cylinder 14 away from the base plate 1 is connected to an input pipe and an output pipe, and the connection between the input pipe and the output pipe and the piston cylinder 14 is connected to a one-way valve. The design of the one-way valve provides a one-way flow path for the fluid, so that the disinfectant flows into the input pipe and then flows out through the output pipe; the end of the input pipe away from the piston cylinder 14 is connected to a storage tank for storing the disinfectant, and the end of the output pipe away from the piston cylinder 14 is connected to the through hole.
[0062] A transmission assembly is mounted on the base plate 1 to drive the piston plate 15. The transmission assembly includes several threaded rods 16 and nut holders 17. The threaded rods 16 are coaxially fixedly engaged with the adjacent main gear 8. The ends of the threaded rods 16, distal from the main gear 8, extend through the interior of the piston cylinder 14 and threadably engage with the adjacent nut holders 17. The nut holders 17 are also fixedly bonded to the adjacent piston plate 15.
[0063] Specifically, when the main gear 8 rotates, it drives the threaded rod 16 coaxially connected thereto to rotate synchronously. Since the threaded rod 16 is threadedly engaged with the nut seat 17, and the nut seat 17 is fixedly bonded to the piston plate 15, when the threaded rod 16 rotates, the threaded engagement can drive the nut seat 17 to move along the axial direction. When the nut seat 17 moves, it drives the piston plate 15 to reciprocate in the piston cylinder 14. In this embodiment, the sliding engagement between the piston plate 15 and the inner wall of the piston cylinder 14 can provide a limit for the piston plate 15, so that it maintains a linear motion trajectory; it enables the piston plate 15 to form suction or thrust in the piston cylinder 14, and when suction is formed, the disinfectant is sucked into the interior of the piston cylinder 14; when thrust is formed, the disinfectant in the interior of the piston cylinder 14 is transported to the through hole. In this embodiment, disinfection and sterilization can be completed each time before the positioning rod 2 adjusts its angle, reducing the risk of mutual infection and further improving the safety of orthopedic positioning drilling.
[0064] The specific implementation process is as follows:
[0065] Before performing orthopedic positioning drilling, place the base plate 1 at the location where the hole needs to be drilled, and align the through hole with the point where the hole needs to be drilled. The controller activates the first motor 5 and the second motor 6, which respectively drive the first rotating rod 3 (X-axis) and the second rotating rod 4 (Y-axis) to rotate around the center of the ball joint of the base plate 1. The semicircular grooves of the first rotating rod 3 and the second rotating rod 4 guide the rotation of the positioning rod 2 through limiting. For example, if the first rotating rod 3 rotates 30°, the positioning rod 2 will be deflected 30° in the XZ plane. If the second rotating rod 4 rotates 45°, the YZ plane angle will be controlled to deflect 45°, so that the positioning rod 2 can accurately point to the target bone surface position.
[0066] As the first and second rotating rods 3 and 4 rotate, the main gear 8, fixedly attached to their outer ends, rotates synchronously. The rotation of the main gear 8 drives the auxiliary gears 9 on both sides, which in turn drive the screw 10 in the opposite direction. For example, if the main gear 8 rotates clockwise, the positioning rod 2 deflects backward. At this time, the left screw 10 pushes the shock absorber 7 toward the inside of the base plate 1, contacting the ball joint between the positioning rod 2 and the base plate 1. The shock absorber 7 is gradually compressed to increase the damping, thereby reducing the vibration amplitude of the positioning rod 2. The right screw 10 moves toward the outside of the base plate 1, releasing and retracting the damping to avoid interfering with the rotation direction of the positioning rod 2. At the same time, the threaded rod 16, coaxially fixed to the main gear 8, rotates with the rotating rod, driving the piston plate 15 to reciprocate within the piston cylinder 14 through the nut seat 17, pumping the disinfectant in the storage tank into the through hole through the one-way valve, completing the pre-sterilization of the channel before the drill bit contacts the bone.
[0067] The present invention combines angle adjustment, shock absorption and buffering with disinfection and sterilization through a mechanical linkage design. When the first rotating rod 3 and the second rotating rod 4 are rotated and positioned, the shock absorber 7 is synchronously driven to move and reciprocate with the piston plate 15. The shock absorber 7 is automatically locked to reduce drilling vibration, and the disinfectant delivery is matched with the drilling channel, thereby performing disinfection and sterilization.
[0068] Example 2:
[0069] As attached Figure 1 As shown, the difference from the above embodiment is that this embodiment further provides a punching robot arm 18 for punching, and the controller is used to control the operation of the punching robot arm 18; in this embodiment, the base plate 1 is detachably connected to the punching robot arm 18.
[0070] The specific implementation process is as follows: Through the integrated drilling robot 18, the orthopedic positioning drilling operation is automated. The drilling path is coordinated with the positioning rod 2 angle, thereby reducing manual operation errors. Automated control is used to synchronize drilling depth, sterilant coverage, and shock absorption, thereby improving surgical safety and efficiency.
[0071] Example 3:
[0072] As attached Figure 1 As shown, the difference from the above embodiment is that a camera 19 is screwed to the punching robot arm 18, and the controller is used to receive and store image information from the camera 19; in this embodiment, the image information is displayed on a display screen. Several angle sensors are also fixedly bonded to the punching robot arm 18, and the controller is used to receive and store angle information from the angle sensors.
[0073] The specific implementation process is as follows: The camera 19 is used to capture the image of the drilling area in real time and transmit it to the controller, providing the doctor with a high-definition visual operation interface to assist in locating bone surface anatomical landmarks. The image storage function fully records the surgical process, facilitating postoperative effect evaluation and operation traceability, and using mechanical collaborative control to enhance the intuitiveness of the operation, thereby reducing the difficulty of surgery in complex cases. The angle sensor is used to monitor the movement posture of the drilling robot arm 18 in real time, providing angle feedback to the device to ensure that the drilling path is consistent with the preset trajectory. When an abnormal angle deviation is detected, correction or emergency braking is automatically triggered, thereby improving surgical safety and operation repeatability.
[0074] Embodiment 4:
[0075] As attached Figure 8 As shown, the difference from the above embodiment is that a straight cylinder 20 for storing disinfectant is fixedly connected to the top of the positioning rod 2 by screws, and a conveying plate 21 is slidably fitted on the inner wall of the straight cylinder 20; a vertical rod 22 is fixedly bonded to the top of the conveying plate 21, and the top of the vertical rod 22 extends to the outside of the straight cylinder 20 and contacts the punching robot arm 18; a conveying pipe is connected to the bottom of the straight cylinder 20, and the end of the conveying pipe away from the straight cylinder 20 is connected to the through hole.
[0076] The specific implementation process is as follows: During the drilling process, the punching robot arm 18 slowly advances toward the positioning rod 2. The vertical rod 22 is designed to push the vertical rod 22 during the drilling process, so that the vertical rod 22 can push the conveying plate 21 to convey the disinfectant inside the straight cylinder 20 to the through hole, thereby achieving simultaneous disinfection of the punching location during the drilling process, further improving the sterility of the device operation. In this embodiment, a sufficient amount of disinfectant is stored in the straight cylinder 20 before each drilling.
[0077] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
