[0036] See also Figure 1-Figure 10 As shown, the present invention provides an arterial catheter removal device, which includes an operating table 1, a baffle 2, a mechanical arm 3, a mounting seat 100, an electric clamp 5, a first visual module 6, a first distance measuring sensor 7 and a controller 8.
[0037] See also Figure 1 and Figure 2As shown, the baffle 2 is semi-circular, and both ends of the baffle 2 are fixedly connected to the operating table 1, and a channel 4 for limbs to be inserted is provided between the baffle 2 and the operating table 1. The mechanical arm 3 is located in the channel 4, and one end of the mechanical arm 3 is fixedly connected to the baffle 2. The mechanical arm 3 can be a six-axis mechanical arm 3, which has six joints, and each joint has a servo motor electrically connected to the controller 8. The controller 8 sends control instructions to these servo motors to realize the movement of the free end of the mechanical arm 3. The mounting seat 100 is fixedly connected to the other end of the mechanical arm 3 by a fastener. The electric gripper 5 is provided with a first gripper finger 9 and a second gripper finger 10, and the electric gripper 5 can drive the first gripper finger 9 and the second gripper finger 10 to move closer or farther from each other. The first visual module 6 and the first distance measuring sensor 7 have the same orientation as the electric gripper 5, and the electric gripper 5, the first visual module 6, and the first distance measuring sensor 7 are all electrically connected to the controller 8 and fixedly connected to the mounting seat 100. The first visual module 6 is used to collect the image in front of the electric gripper 5 in real time, and transmit the collected image information to the controller 8 in the form of electrical signals. The controller 8 controls the movement of the robot arm 3 according to the image information.
[0038] The first visual module 6 in the present invention can be a camera, the first distance sensor 7 can be a laser distance sensor or an infrared distance sensor, and the controller 8 can be a Siemens S7-300PLC. The direction of the electric gripper 5 refers to the direction in which the gripping fingers on the electric gripper 5 extend forward, the direction of the visual module refers to the field of view of the camera, and the direction of the distance sensor refers to the light emission direction of the laser distance sensor or the infrared distance sensor. In some embodiments, the aforementioned electric gripper 5 can also be replaced by a pneumatic gripper.
[0039] Before the arterial catheter removal device is used, the mechanical arm 3 is curled up in the upper half of the channel 4, so that a large enough space is left below it for the patient's limbs to be inserted. When the arterial catheter removal device is used, the patient's limbs are first placed on the operating table 1 and the patient's limbs are kept still. Then the first visual module 6 collects the image information on the operating table 1. The controller 8 determines the position of the arterial catheter and the puncture direction according to the image information, and sends a corresponding control instruction to the mechanical arm 3, so that the free end of the mechanical arm 3 moves to the top of the arterial catheter. During this process, the first distance sensor 7 detects the distance between the clamping finger and the patient's limb, and the first distance sensor 7 transmits the detected data to the controller 8. When the distance between the clamping finger and the patient's limb reaches the set value, the controller 8 controls the electric clamp 5 to perform the clamping action, so that the first clamping finger 9 and the second clamping finger 10 clamp the arterial catheter, and then the controller 8 controls the mechanical arm 3 to move to remove the arterial catheter.
[0040] In order to prevent the patient's limbs from unconsciously moving, the arterial catheter removal device also includes a first fixing belt 11 and a second fixing belt 12 arranged at intervals. One end of the first fixing belt 11 and the second fixing belt 12 are both fixedly connected to the operating table 1, and the other ends of the first fixing belt 11 and the second fixing belt 12 are both detachably connected to the operating table 1, and the baffle 2 is located between the first fixing belt 11 and the second fixing belt 12. The other ends of the first fixing belt 11 and the second fixing belt 12 can be connected to the operating table 1 using Velcro, and the Velcro fur surface is provided on the first fixing belt 11 and the second fixing belt 12, and the Velcro hook surface is provided on the operating table 1, so that the patient's limbs can be easily fixed.
[0041] In the present invention, the arterial catheter removal device further includes a hemostatic component 200, a second visual module 13, and a second distance measuring sensor 14. The hemostatic component 200 and the electric clamp 5 are respectively located at both ends of the mounting seat 100, and the end of the hemostatic component 200 away from the electric clamp 5 has a cotton ball 15; the hemostatic component 200, the second visual module 13, and the second distance measuring sensor 14 are all connected to the mounting seat 100, and the orientation of the second visual module 13 and the second distance measuring sensor 14 is opposite to that of the first visual module 6 and are both electrically connected to the controller 8.
[0042] After the arterial catheter removal device removes the arterial catheter, the controller 8 controls the sixth axis of the robotic arm 3 to rotate so that the hemostasis component 200, the second visual module 13 and the second ranging sensor 14 face downward, and then the second visual module 13 and the second ranging sensor 14 are started, the second visual module 13 collects image information of the patient's limb and transmits this information to the controller 8, the controller 8 determines the position of the puncture port through analysis, and then the controller 8 controls the robotic arm 3 to move the cotton ball 15 on the hemostasis component 200 to above the puncture port, and then the controller 8 controls the robotic arm 3 to move the cotton ball 15 on the hemostasis component 200 to descend and press on the puncture port. During the descent of the cotton ball 15 on the hemostasis component 200, the second ranging sensor 14 measures the distance between the hemostasis component 200 and the patient's limb, thereby ensuring that the cotton ball 15 is pressed on the puncture port with appropriate force.
[0043] See also Figures 5 to 7As shown, the hemostatic assembly 200 of the present invention also includes a bracket 16, a guide rod 17, a slider 18, a compression spring 19 and an arc plate 20. The bracket 16 can be bent into an L-shape by a metal plate, and then fixed to the mounting seat 100 by a fastener, and one end of the guide rod 17 is fixedly connected to the bracket 16. The slider 18 is connected to the guide rod 17, and the slider 18 can slide along the length direction of the guide rod 17. The compression spring 19 is located between the bracket 16 and the slider 18, and the compression spring 19 is used to drive the slider 18 to move in a direction away from the electric clamp 5. The shape of the arc plate 20 is an arc, one side of the arc plate 20 is a concave surface, and the other side is a convex surface. A connecting portion 2001 is provided on the convex surface of the arc plate 20, and the connecting portion 2001 is connected to the slider 18. The cotton ball 15 is arranged on the concave surface of the arc plate 20, wherein the arc plate 20 and the cotton ball 15 are both disposable items.
[0044] The arc plate 20 can be made of a material with elastic deformation ability, such as rubber. When the cotton ball 15 is pressed on the puncture hole, the arc plate 20 can be deformed according to the thickness of the patient's limbs to adapt to different patients. The aforementioned compression spring 19 can be a compression spring with a smaller stiffness coefficient. During the design and assembly, the slider 18 and the guide rod 17 should have as little friction as possible; during the hemostasis period of the hemostasis component 200, the cotton ball 15 is first deformed to completely cover the puncture hole, and then the arc plate 20 is pressed around the puncture hole with a certain force. In this process, the compression spring 19 will be compressed by force. The hemostasis component 200 itself has a certain elastic adjustment ability, which can reduce the measurement accuracy requirements for the second distance sensor 14, and can effectively avoid human limbs from being crushed, thereby improving the user experience.
[0045] In a further improvement, the hemostasis assembly 200 further includes a pressure sensor 21 located between the bracket 16 and the compression spring 19. One end of the compression spring 19 near the bracket 16 contacts the pressure sensor 21, and the pressure sensor 21 is electrically connected to the controller 8. Since the friction between the slider 18 and the guide rod 17 is relatively small, it can be known from the force analysis that the pressure applied by the compression spring 19 on the pressure sensor 21 is close to the pressing force of the arc plate 20 and the cotton ball 15 on the patient's limbs. Therefore, the pressure sensor 21 can be set to more accurately measure the pressing force of the arc plate 20 and the cotton ball 15 on the patient's limbs. The controller 8 can control the mechanical arm 3 more accurately based on the data measured by the pressure sensor 21 to ensure that the arc plate 20 and the cotton ball 15 are pressed on the patient's limbs with appropriate force.
[0046] In order to facilitate the connection between the arc plate 20 and the slider 18, the hemostasis assembly 200 further includes a magnetic member 22 disposed on the slider 18 and an iron sheet 23 embedded in the connecting portion 2001. The magnetic member 22 can be a permanent magnet or an electromagnet. The magnetic force between the magnetic member 22 and the iron sheet 23 can make the arc plate 20 adsorbed on the slider 18. It should be noted that the aforementioned iron sheet 23 can also be replaced by a magnetic metal sheet such as nickel or cobalt.
[0047] In a preferred embodiment, the magnetic member 22 can be an electromagnet, and the power on and off of the magnetic member 22 can be controlled by the controller 8. At this time, a box of unused arc plates 20 can be placed next to the operating table 1. Through the set program, the robotic arm 3 can automatically go to the placement position of the unused arc plates 20. After the magnetic member 22 is powered on, the arc plates 20 can be automatically taken out; and a medical waste bin can be placed next to the operating table 1. After the hemostasis pressing is completed, the controller 8 controls the movement of the robotic arm 3 and throws the used arterial catheter and arc plate 20 into the medical waste bin. In this way, the removal of the arterial catheter is highly automated, which is beneficial to saving manpower.
[0048] In the present invention, a cylindrical countersunk hole 1801 is provided at one end of the slider 18, and one end of the compression spring 19 is inserted into the countersunk hole 1801. The aforementioned magnetic member 22 can also be installed in the countersunk hole 1801, and the countersunk hole 1801 can be used to limit the compression spring 19 to prevent the position of the compression spring 19 from deviating.
[0049] See also Figure 5 As shown, there are two guide rods 17, the compression spring 19 is located between the two guide rods 17, the slider 18 has a first ear plate 1802 and a second ear plate 1803, the first ear plate 1802 and the second ear plate 1803 are respectively provided with a first through hole 18021 and a second through hole 18031, one guide rod 17 is inserted into the first through hole 18021, the other guide rod 17 is inserted into the second through hole 18031, and a stopper 1701 is provided at one end of the guide rod 17 away from the bracket 16. In specific implementation, grease can be applied to the guide rod 17 to reduce the friction between the slider 18 and the guide rod 17. In addition, linear bearings can be added in the first through hole 18021 and the second through hole 18031, and the friction between the slider 18 and the guide rod 17 can be reduced by assembling the guide rod 17 in the linear bearings.
[0050] In the present invention, two insert blocks 1804 are provided at one end of the slider 18 away from the bracket 16, and two slots 2002 are provided on the connecting portion 2001, and the insert blocks 1804 can be inserted into the corresponding slots 2002. The insert blocks 1804 and the slots 2002 can effectively prevent the arc plate 20 from rotating relative to the slider 18, ensuring that the arc plate 20 is pressed on the patient's limb at a correct angle.
[0051] See also Figure 3a and Figure 3b As shown, the mounting base 100 in the present invention can be composed of a bottom shell 24 and an upper cover 25, the electric clamp 5 and the hemostasis assembly 200 are installed on the bottom shell 24, and after the upper cover 25 is buckled with the bottom shell 24, the electric clamp 5, the bracket 16, the guide rod 17, the compression spring 19, and the pressure sensor 21 are all enclosed in the space formed by the upper cover 25 and the bottom shell 24, the first clamp finger 9 and the second clamp finger 10 extend to the outside of the upper cover 25 and the bottom shell 24, and the visual module and the ranging sensor can be connected to the upper cover 25.
[0052] The structure of the first clamping finger 9 is shown in Fig.10 As shown, the first clamping finger 9 is composed of a flat plate portion 901 and a finger body portion 902 connected to each other. The flat plate portion 901 is fixedly connected to the electric clamping claw 5 by bolts, and a V-shaped groove 26 is provided at one end of the finger body portion 902 away from the flat plate portion 901. Figure 4 As shown, the structures of the first clamping finger 9 and the second clamping finger 10 are mirror-symmetrical. After the first clamping finger 9 and the second clamping finger 10 are mounted on the electric clamping jaw 5, the V-shaped groove 26 on the first clamping finger 9 is opposite to the V-shaped groove 26 on the second clamping finger 10. When the first clamping finger 9 and the second clamping finger 10 are clamping the arterial catheter, the arterial catheter is clamped in the two V-shaped grooves 26.
[0053] The arterial catheter removal device provided by the present invention realizes the automation and standardization of arterial catheter removal and puncture point pressing to stop bleeding. There is no need to manually remove the arterial catheter and manually press the puncture point, which is beneficial to saving time of medical staff.
