Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a portable medical multi-functional clamping device. Background Art

[0002] During a surgical operation, a doctor needs to precisely operate and position various tissues, organs, tools, etc. Clamping devices are widely used in surgeries, such as fixing fracture sites in orthopedic surgeries and clamping joint prostheses in joint surgeries. Such devices are usually made of titanium alloy with good biocompatibility and corrosion resistance, and have good stability and flexibility to meet the requirements of different surgical scenarios.

[0003] In the prior art, for example, the patent with the publication number "CN110107782A" discloses a medical rapid clamping device. This patent has a simple structure, is easy to use, has a fast clamping speed and saves time, and can clamp objects with various shapes. However, it only has a single clamping function. When a doctor needs to perform other operations, other auxiliary tools need to be replaced, resulting in the limitation of the single function of the device.

[0004] In summary, how to solve the problem that the clamping device in the prior art only has a single clamping function, resulting in the limitation of the single function of the device has become a difficult problem that needs to be solved urgently in the current field. Therefore, it is necessary to propose a portable medical multi-functional clamping device. Summary of the Invention

[0005] To solve the above problems, the present invention provides a portable medical multi-functional clamping device. Through the combined operation of each component, it can not only clamp an object, but also fix the clamping arm, and can disinfect the clamped object. For objects in narrow areas, the clamping arm can adjust its angle and can also dissipate heat for the power component, thereby increasing the versatility and reliability of the device.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A portable medical multi-functional clamping device includes a housing and a handle. Clamping arms are symmetrically hinged on the housing, and a clamping component for driving the clamping arms to clamp is arranged inside the housing.

[0007] The clamping component includes a C-shaped moving plate. On one side of the moving plate close to the clamping arm, clamping rods are symmetrically and fixedly connected. Moving grooves for the clamping rods to slide are respectively formed on the clamping arms. The moving grooves on the side away from the housing are inclined towards the outside of the clamping arms. On the side of the moving plate away from the clamping arm, a cross bar is fixedly connected, and a limiting block is fixedly connected to the inner side wall of the housing. One end of the cross bar away from the moving plate penetrates through the limiting block and is in sliding fit with the limiting block.

[0008] A driving component for driving the cross bar to reciprocate is arranged on the housing.

[0009] The cross bar is provided with a fixing component for maintaining the clamping force of the clamping arms and a disinfection component for disinfecting the clamped object; the driving component is used to drive the fixing component and the disinfection component to run synchronously.

[0010] The handle is provided with a horizontal adjustment component for adjusting the horizontal angle of the clamping arms and a vertical adjustment component for adjusting the vertical angle of the clamping arms.

[0011] The housing is provided with a heat dissipation component for dissipating heat from the driving component; the horizontal adjustment component is used to drive the heat dissipation component to run synchronously.

[0012] The technical principle of the above solution is as follows:

[0013] The driving component drives the cross bar to move reciprocally. Since the clamping arms are all hinged to the housing, moving grooves are formed on the clamping arms, a clamping rod sliding in the moving groove is fixedly connected to the moving plate, and the moving plate is fixedly connected to the cross bar; therefore, the cross bar can drive the moving plate to move reciprocally, and the moving plate drives the clamping rod to slide in the moving groove. Through the inclined design of the moving groove, the moving plate can drive the clamping rod to make the clamping arms approach each other, thereby fixing the object. In this process, the limiting block provides a limiting effect on the cross bar to keep its linear movement track. The design of the fixing component can stabilize the clamping force of the clamping arms, thereby further improving the clamping stability, and the disinfection component can disinfect the clamped object. The horizontal adjustment component and the vertical adjustment component can respectively adjust the rotation angle of the clamping arms so that they can perform clamping operations on narrow surgical areas, and the heat dissipation component can dissipate heat from the driving component, further improving the service life of the device.

[0014] Adopting the above solution has the following beneficial effects:

[0015] 1. The present invention drives the cross bar to move reciprocally through the driving component, and then cooperates with the moving plate and the clamping rod with the moving grooves on the clamping arms; the inclined design of the moving groove enables the clamping rod to gradually apply pressure to the clamping arms during the sliding process, thereby ensuring uniform and continuous clamping force and enabling the clamping arms to perform precise opening and closing actions. Ensure that the clamping device can provide consistent and reliable clamping force on objects of different sizes and shapes. Compared with the existing devices that require manual clamping operations, through an automated control method, the operation accuracy and convenience are improved.

[0016] 2. Compared with the existing clamping devices with insufficient fixing force, the present invention further enhances the clamping stability of the clamping arms through the design of the fixing component, ensuring that the clamping arms maintain close contact when clamping an object and are not easily loosened even under external forces. Make the clamping force remain constant during the operation, reduce the change of the clamping force caused by external factors, and thus improve the reliability of the clamping process.

[0017] 3. Compared with the prior art that cannot clamp target objects in narrow areas, the present invention uses the designs of the horizontal adjustment component and the vertical adjustment component, enabling the clamping arm to be flexibly adjusted in multiple directions, so that the device can adapt to workspaces of different shapes and sizes, especially suitable for narrow surgical areas, further improving the versatility and convenience of the device and meeting the application requirements of different scenarios. The heat dissipation component can dissipate heat for the driving components of the device, further extending the service life of the device.

[0018] Furthermore, the driving component includes a controller, a rotating member, a vertical plate, and a rotating wheel. The controller is used to control the rotation of the rotating member; both the controller and the rotating member are fixedly connected to the outer wall of the housing. The output shaft of the rotating member penetrates the housing and is coaxially fixedly connected to the rotating wheel. The rotating wheel is rotationally matched with the inner side wall of the housing; a toggle rod is eccentrically fixedly connected to one side of the rotating wheel away from the rotating member. A sliding groove for the toggle rod to slide is formed on the vertical plate; one end of the cross bar away from the moving plate is fixedly connected to the vertical plate.

[0019] Beneficial effects: By driving the rotating wheel to rotate through the rotating member, since the toggle rod is fixedly connected to the rotating wheel and the vertical plate is provided with a sliding groove for the toggle rod to slide, and the vertical plate is fixedly connected to the cross bar, during the process of the rotating wheel driving the toggle rod to rotate, the toggle rod can drive the vertical plate to perform reciprocating motion, thereby driving the cross bar to perform synchronous reciprocating motion by means of the vertical plate.

[0020] Furthermore, the fixing component includes connecting rods symmetrically and fixedly connected to the outer wall of the cross bar. Hinge rods are hinged to one end of each connecting rod away from the cross bar; blocking blocks are hinged to one end of each hinge rod away from the connecting rod. One end of each blocking block close to the moving plate is hinged to the inner side wall of the housing.

[0021] Beneficial effects: During the reciprocating motion of the cross bar, it can drive the connecting rods to move synchronously. Since the connecting rods are all hinged to the hinge rods, and the other ends of the hinge rods are all hinged to the blocking blocks, and one end of each blocking block is hinged to the inner side wall of the housing; when the cross bar drives the moving plate to clamp the clamping arm, the cross bar will pull the hinge rods through the connecting rods, and the hinge rods will pull the blocking blocks to closely contact the rotating wheel, preventing the rotating wheel from rotating, and the fixing force will be more stable when clamping smaller objects. On the contrary, it can push the blocking blocks away so that they do not contact the rotating wheel, enabling the rotating wheel to rotate, further improving the flexibility and stability of the clamping arm for clamping objects.

[0022] Furthermore, the disinfection component includes a first rod, a first plate, and a first cylinder. The first cylinder is fixedly connected to the inner side wall of the housing. The first plate is slidably matched with the inner wall of the first cylinder; one end of the first rod is fixedly connected to the outer wall of the cross bar, and the other end of the first rod penetrates the first cylinder and is fixedly connected to the first plate.

[0023] On one side of the first cylinder away from the first rod, an input pipe and an output pipe are connected. One-way valves are connected to the joints of the input pipe and the output pipe with the first cylinder. The end of the input pipe away from the first cylinder is connected to a storage barrel for storing disinfectant, and the storage barrel is detachably connected to the outer wall of the housing. The end of the output pipe away from the first cylinder is connected to the side of the clamping arm away from the housing.

[0024] Beneficial effects: The cross bar drives the first rod to reciprocate, and the first rod drives the first plate to reciprocate in the first cylinder. When the first plate reciprocates, it can generate suction or thrust. When generating suction, it can suck the disinfectant in the storage barrel into the first cylinder, and when generating thrust, it can transport the disinfectant in the first cylinder to the clamping area of the clamping arm, thereby realizing the disinfection and sterilization of the clamped object, which is beneficial to improving the safety of the surgical process.

[0025] Furthermore, the horizontal adjustment component includes a cross bar, a first gear, and a first telescopic member. The controller is used to control the first telescopic member to expand and contract. The first telescopic member is fixedly connected to the outer wall of the housing, and the output shaft of the first telescopic member is fixedly connected to a first rack. The first gear is fixedly connected to the outer wall of the vertical end of the cross bar, and the first gear meshes with the first rack. The side of the housing away from the clamping arm is rotationally matched with the vertical end of the cross bar, and the handle is rotationally matched with the horizontal end of the cross bar.

[0026] Beneficial effects: The first telescopic member drives the first rack to expand and contract. Since the first rack meshes with the first gear, the first gear is fixedly connected to the vertical end of the cross bar, the first telescopic member is fixedly connected to the outer wall of the housing, the vertical end of the cross bar is rotationally matched with the housing, and the handle is rotationally matched with the horizontal end of the cross bar. Therefore, the first rack can drive the first telescopic member to rotate around the first gear, causing the first telescopic member to drive the housing to rotate around the cross bar, which can change the horizontal angle and position of the housing, enabling the clamping arm to clamp the target object in a narrow area during the surgical process, further improving the portability of the device.

[0027] Furthermore, the vertical adjustment component includes a second telescopic member, a second gear, and a second rack. The controller is used to control the second telescopic member to expand and contract. The second telescopic member is fixedly connected to the outer wall of the handle, and the output shaft of the second telescopic member is fixedly connected to the second rack. The second gear is fixedly connected to the outer wall of the horizontal end of the cross bar, and the second gear meshes with the second rack.

[0028] Beneficial effects: The second telescopic member drives the second rack to expand and contract. Since the second rack meshes with the second gear, and the second gear is fixedly connected to the outer wall of the horizontal end of the cross bar, the second rack can drive the second gear to rotate, and when the second gear rotates, it can drive the cross bar to rotate synchronously, enabling the housing to adjust the angle in the vertical direction, so that the rotation range of the clamping arm is wider. Through this multi-angle adjustment design, the versatility and flexibility of the device are further improved.

[0029] Furthermore, the heat dissipation component includes a second cylinder fixedly connected to the outer wall of the housing. A second plate is slidably fitted to the inner wall of the second cylinder. A second rod is fixedly connected to the second plate, and the end of the second rod away from the second plate extends to the outside of the second cylinder and is fixedly connected to the output shaft of the first telescopic member.

[0030] An intake pipe and an outlet pipe are connected to one side of the second cylinder away from the second rod. Second one-way valves are connected to the joints of the intake pipe and the outlet pipe with the second cylinder. The intake pipe is connected to the outside of the second cylinder, and the end of the outlet pipe away from the second cylinder is connected to the outside of the rotating member.

[0031] Beneficial effects: During the telescopic process of the first telescopic member, it can drive the second plate to reciprocate, so that the second plate can generate suction or thrust in the second cylinder. When generating suction, it can transmit external gas to the outside of the rotating member, thereby using the gas to purge the rotating member, achieving the heat dissipation effect of the rotating member, and further helping to improve the service life of the device.

[0032] Furthermore, buffer layers are fixedly connected to the clamping arms.

[0033] Beneficial effects: The design of the buffer layer can increase the friction force at the clamping part and also provide flexible support for it.

[0034] Furthermore, pressure sensors are fixedly connected to the sides of the buffer layers away from the clamping arms. The controller is used to receive the pressure information sent by the pressure sensors and control the rotation of the rotating member based on the pressure information.

[0035] Beneficial effects: By monitoring the clamping pressure information in real time through the pressure sensors and analyzing and feedback the data of the pressure sensors by the controller, more precise clamping control can be achieved.

[0036] Furthermore, the end of the output pipe away from the first cylinder is also connected to an atomizing nozzle.

[0037] Beneficial effects: Through the design of the atomizing nozzle, the treatment range of the disinfectant can be further expanded, and at the same time, a more uniform disinfection effect can be achieved.

[0038] The additional aspects and advantages of the present invention will be partially given in the following description, partially will become obvious from the following description, or will be understood through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The following is a more detailed description through specific implementation manners:

Clamping arms 2 are symmetrically hinged on the outer shell 1, and a clamping component for driving the clamping arms 2 to clamp is arranged inside the outer shell 1.

On the side of the moving plate 3 close to the clamping arm 2, clamping rods 4 are symmetrically fixed by screws; moving grooves for the clamping rods 4 to slide are opened on the clamping arms 2, and the sides of the moving grooves away from the outer shell 1 are inclined towards the outside of the clamping arms 2; a cross bar 5 is fixed by screws on the left side of the moving plate 3, and a limit block 6 is fixed by screws on the inner side wall of the outer shell 1; the left end of the cross bar 5 penetrates through the limit block 6 and is in sliding fit with the limit block 6.

[0049] A driving component for driving the cross bar 5 to reciprocate is provided on the outer shell 1.

In this embodiment, the rotating member is a motor 7; the controller is used to control the rotation of the motor 7; the controller and the motor 7 are both fixedly connected to the outer wall of the outer shell 1 by screws, the output shaft of the motor 7 penetrates through the outer shell 1 and is fixedly clamped coaxially with the rotating wheel 9, and the rotating wheel 9 is rotationally matched with the inner side wall of the outer shell 1; a shifting rod 10 is integrally formed eccentrically on one side of the rotating wheel 9 away from the motor 7, and a sliding groove for the shifting rod 10 to slide is formed on the vertical plate 8; the left end of the cross bar 5 is fixedly connected to the vertical plate 8 by screws.

[0050] A fixing component for maintaining the clamping force of the clamping arm 2 and a disinfection component for disinfecting the clamped object are provided on the cross bar 5; the driving component is used to drive the fixing component and the disinfection component to operate synchronously.

[0051] The fixing component includes connecting rods 11 symmetrically and fixedly connected to the outer wall of the cross bar 5 by screws, and hinge rods 12 are hinged to the other ends of the connecting rods 11; hinge blocks 13 are hinged to the other ends of the hinge rods 12, and the right ends of the hinge blocks 13 are hinged to the inner side wall of the outer shell 1.

[0052] Combined Figure 4 As shown, the disinfection component includes a first rod 14, a first plate 15 and a first cylinder 16. The first cylinder 16 is fixedly connected to the inner side wall of the outer shell 1 by screws, and the first plate 15 is slidably matched with the inner wall of the first cylinder 16; one end of the first rod 14 is fixedly connected to the outer wall of the cross bar 5 by screws, and the other end of the first rod 14 penetrates through the first cylinder 16 and is fixedly bonded to the first plate 15.

[0053] An input pipe and an output pipe are connected to the right side of the first cylinder 16, and first one-way valves are connected to the joints of the input pipe and the output pipe with the first cylinder 16; the other end of the input pipe is connected to a storage bucket for storing disinfectant, and the storage bucket is detachably clamped and connected to the outer wall of the outer shell 1; the other end of the output pipe is connected to the side of the clamping arm 2 away from the outer shell 1.

[0054] Combined Figure 1 As shown, a horizontal adjustment component for adjusting the horizontal angle of the clamping arm 2 and a vertical adjustment component for adjusting the vertical angle of the clamping arm 2 are provided on the handle 17.

[0055] The horizontal adjustment component includes a cross bar 18, a first gear 19 and a first telescopic member. In this embodiment, the first telescopic member is a first electric push rod 20; the controller is used to control the telescopic movement of the first electric push rod 20; the first electric push rod 20 is fixedly connected to the outer wall of the outer shell 1 by screws, and a first rack 21 is fixedly connected to the output shaft of the first electric push rod 20; the first gear 19 is fixedly clamped to the outer wall of the vertical end of the cross bar 18, and the first gear 19 meshes with the first rack 21; the outer shell 1 is rotationally matched with the vertical end of the cross bar 18, and the handle 17 is rotationally matched with the horizontal end of the cross bar 18.

[0056] The vertical adjustment assembly includes a second telescopic member, a second gear 23 and a second rack 24. In this embodiment, the second telescopic member is a second electric push rod 22; the controller is used to control the second electric push rod 22 to extend and retract; the second electric push rod 22 is screw-fixedly connected to the outer wall of the handle 17, and the output shaft of the second electric push rod 22 is screw-fixedly connected to the second rack 24; the second gear 23 is fixedly clamped on the outer wall of the horizontal end of the cross rod 18, and the second gear 23 and the second rack 24 are meshed with each other.

[0057] The housing 1 is provided with a heat dissipation component for dissipating heat for the driving component; the transverse adjustment component is used to drive the heat dissipation component to operate synchronously.

[0058] Combination Figure 5 As shown, the heat dissipation assembly includes a second tube 25 fixedly connected to the outer wall of the shell 1 by screws, and the inner wall of the second tube 25 is slidably matched with a second plate 27; a second rod 26 is fixedly bonded to the second plate 27, and the left end of the second rod 26 extends to the outside of the second tube 25 and is fixedly connected to the output shaft of the first electric push rod 20 by screws.

[0059] The right side of the second tube 25 is connected with an air inlet pipe and an air outlet pipe, and the connection between the air inlet pipe and the air outlet pipe and the second tube 25 is connected with a second one-way valve; the air inlet pipe is connected to the outside of the second tube 25, and the end of the air outlet pipe away from the second tube 25 is connected to the outside of the motor 7.

[0060] The specific implementation process is as follows:

[0061] First, before the operation, when an object needs to be clamped, the motor 7 drives the rotating wheel 9 to rotate. Since the rotating wheel 9 is integrally formed with a toggle rod 10, the vertical plate 8 has a slide groove for the toggle rod 10 to slide, and the vertical plate 8 is fixedly connected to the cross bar 5 with screws, the toggle rod 10 can drive the vertical plate 8 to reciprocate during the process of the rotating wheel 9 driving the toggle rod 10 to rotate, thereby using the vertical plate 8 to drive the cross bar 5 to reciprocate synchronously. Figure 3 For example, when the toggle rod 10 drives the vertical plate 8 to rotate to the right side of the rotating wheel 9, the vertical plate 8 drives the cross bar 5 to move to the right side; otherwise, the cross bar 5 can move to the left side.

[0062] During the reciprocating motion of the cross bar 5, since the clamping arms 2 are hinged to the outer shell 1, movable grooves are opened on the clamping arms 2, and the moving plate 3 is fixedly connected with the clamping rod 4 that slides with the movable groove by screws, and the moving plate 3 is fixedly connected with the cross bar 5 by screws; therefore, the moving plate 3 can be driven to reciprocate by the cross bar 5, and the moving plate 3 drives the clamping rod 4 to slide in the moving groove. The inclined design of the moving groove can make the moving plate 3 drive the clamping rod 4 to realize the two symmetrical clamping arms 2 approaching each other, thereby fixing the object.

[0063] by Figure 3For example, when the cross bar 5 drives the moving plate 3 to move to the right, the clamping rod 4 slides to the right in the moving groove and drives the clamping arm 2 to clamp towards the middle; conversely, it can release the clamped object. In this process, the limiting block 6 provides a limiting effect for the cross bar 5 to keep its linear movement trajectory.

[0064] During the reciprocating movement of the cross bar 5, it can drive the connecting rod 11 to move synchronously. Since the connecting rods 11 are all hinged to the hinge rods 12, and the other ends of the hinge rods 12 are all hinged to the blocking blocks 13, and the right ends of the blocking blocks 13 are all hinged to the inner side wall of the housing 1; therefore, when the cross bar 5 drives the moving plate 3 to clamp the clamping arm 2, the cross bar 5 will pull the hinge rod 12 to move through the connecting rod 11, and the hinge rod 12 will pull the blocking block 13 into close contact with the rotating wheel 9, so that the rotating wheel 9 will not rotate, and when clamping a smaller object, its fixing force will be more stable.

[0065] Conversely, it can push the blocking block 13 away so that the blocking block 13 does not contact the rotating wheel 9, enabling the rotating wheel 9 to rotate, further improving the flexibility and stability of the clamping arm 2 when clamping an object. Figure 3 For example, when the cross bar 5 drives the connecting rod 11 to move to the right, the hinge rod 12 will pull the blocking block 13 into contact with the outer wall of the rotating wheel 9, and conversely, it can push the blocking block 13 away.

[0066] By driving the first rod 14 to reciprocate through the cross bar 5, the first rod 14 drives the first plate 15 to reciprocate in the first cylinder 16. When the first plate 15 reciprocates, it can generate suction or thrust. When generating suction, it can suck the disinfectant in the storage barrel into the first cylinder 16, and when generating thrust, it can transport the disinfectant in the first cylinder 16 to the clamping area of the clamping arm 2, thereby realizing the disinfection and sterilization effect on the clamped object, and further facilitating the improvement of the safety during the operation process.

[0067] When it is necessary to adjust the angle of the clamping arm 2, the first electric push rod 20 drives the first rack 21 to expand and contract. Since the first rack 21 meshes with the first gear 19, the first gear 19 is fixedly clamped to the vertical end of the cross bar 18, the first electric push rod 20 is fixedly connected to the outer wall of the housing 1 by screws, the vertical end of the cross bar 18 is rotationally matched with the housing 1, and the handle 17 is rotationally matched with the horizontal end of the cross bar 18; therefore, the first electric push rod 20 can be driven to rotate around the first gear 19 through the expansion and contraction of the first rack 21, so that the first electric push rod 20 drives the housing 1 to rotate around the cross bar 18, thereby being able to change the angle and position of the housing 1 in the horizontal position, and the housing 1 drives the angle of the clamping arm 2 to be adjusted in the horizontal position; enabling the clamping arm 2 to clamp the target object in a narrow area during the operation process, further improving the portability of the device.

[0068] For Figure 1For example, when the first electric push rod 20 drives the first rack 21 to extend, the housing 1 deflects to the right; conversely, when the first electric push rod 20 drives the first rack 21 to shorten, the housing 1 deflects to the left.

[0069] The second electric push rod 22 drives the second rack 24 to expand and contract. Since the second rack 24 meshes with the second gear 23, and the second gear 23 is fixedly clamped to the outer wall of the horizontal end of the cross rod 18, the rotation of the second gear 23 can be driven by the expansion and contraction of the second rack 24. When the second gear 23 rotates, it can drive the cross rod 18 to rotate synchronously, enabling the housing 1 to adjust the angle in the vertical direction, thereby increasing the rotation range of the clamping arm 2. Through this multi-angle adjustment design, the versatility and flexibility of the device are further improved. For Figure 1 example, when the second rack 24 extends and drives the second gear 23 to rotate clockwise, the housing 1 deflects downward through the cross rod 18; conversely, the housing 1 can be deflected upward.

[0070] During the extension and contraction of the first electric push rod 20, the second rod 26 will move synchronously. In this embodiment, the second rod 26 is L-shaped. One end of the second rod 26 is fixedly connected to the first electric push rod 20 by screws, and the other end is fixedly bonded to the second plate 27. Therefore, the reciprocating movement of the second plate 27 can be driven by the movement of the second rod 26, so that the second plate 27 can generate suction or thrust in the second cylinder 25. When suction is generated, the external gas can be transmitted to the outside of the motor 7, and the gas is used to purge the motor 7, thereby achieving the heat dissipation effect of the motor 7, and further helping to improve the service life of the device.

[0071] In the prior art, some clamping and fixing devices often only have simple clamping or fixing functions, which have certain limitations. In this embodiment, the rotating wheel 9 drives the cross bar 5 to move reciprocally, and then through the cooperation of the moving plate 3 and the clamping rod 4 with the moving groove on the clamping arm 2; the inclined design of the moving groove enables the clamping rod 4 to gradually apply pressure to the clamping arm 2 during the sliding process, thereby ensuring that the clamping force is uniform and continuous, enabling the clamping arm 2 to achieve precise opening and closing actions. Ensure that the clamping device can provide a consistent and reliable clamping force on objects of different sizes and shapes, and through an automated control method, thereby improving the accuracy and convenience of operation.

[0072] The design of the blocking block 13 further enhances the clamping stability of the clamping arm 2, ensuring that the clamping arm 2 maintains close contact when clamping an object and is not easily loosened even under external forces. The clamping force remains constant during the operation, reducing the change in the clamping force caused by external factors, thereby improving the reliability of the clamping process.

[0073] Utilizing the design of the first gear 19 and the second gear 23 on the cross bar 18, driven by the first electric push rod 20 and the second electric push rod 22, the clamping arm 2 can be flexibly adjusted in multiple directions, enabling the device to adapt to workspaces of different shapes and sizes, especially suitable for narrow surgical areas, further enhancing the versatility and convenience of the device. The form of gas generated by the second plate 27 is transmitted to the outside of the motor 7, and the gas can provide heat dissipation for the driving components of the device, further increasing the service life of the device.

[0074] Embodiment 2:

[0075] As shown in the Figure 1 accompanying drawings, the difference from the above embodiment is that buffer layers 28 are fixedly bonded to the clamping arms 2. In this embodiment, the material of the buffer layer 28 is preferably medical silicone.

[0076] The specific implementation process is as follows: The design of the buffer layer 28 can increase the friction force at the clamping part and also provide flexible support for it, further enhancing the safety of the device during clamping.

[0077] Embodiment 3:

[0078] The difference from the above embodiment is that pressure sensors are fixedly bonded to the sides of the buffer layers 28 away from the clamping arms 2. The controller is used to receive the pressure information sent by the pressure sensors and control the rotation of the motor 7 based on the pressure information.

[0079] The specific implementation process is as follows: By real-time monitoring of the clamping pressure information through the pressure sensors, and through the analysis and feedback of the pressure sensor data by the controller, more precise clamping control can be achieved.

[0080] Embodiment 4:

[0081] As shown in the Figure 4 accompanying drawings, the difference from the above embodiment is that the end of the output pipe away from the first cylinder 16 is also connected to an atomizing nozzle 29.

[0082] The specific implementation process is as follows: Through the design of the atomizing nozzle 29, the treatment range of the disinfectant can be further expanded, and at the same time, a more uniform disinfection effect can be achieved, thereby reducing the risk of surgical infections.

[0083] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
