Description

Technical Field

[0001] This application relates to the technical field of pulmonary nodule treatment, and in particular to a processing device and method for processing anti-cut positioning wires for pulmonary nodule localization and detection. Background Technology

[0002] In existing technologies, the treatment of lung nodules requires first using nickel-titanium wire for localization and detection, and then performing minimally invasive surgery using an electrocautery knife.

[0003] Nickel-titanium wire is a shape-memory metal and is conductive. During minimally invasive surgery, the movement of the electrosurgical unit will inevitably touch the nickel-titanium wire, which may cause it to be cut, affecting the use of the entire surgical procedure, or even causing some of it to be left in the human body, resulting in medical accidents. Therefore, it is necessary to provide a cut-proof positioning wire and related processing equipment to reduce the risk of medical accidents. Summary of the Invention

[0004] To reduce the risk of medical accidents, this application provides a processing device and method for processing anti-cut positioning wires for lung nodule localization detection.

[0005] Firstly, this application provides a processing device for anti-cut positioning wire for lung nodule localization detection, which adopts the following technical solution: A device for processing anti-cut positioning wire for lung nodule localization detection includes a nickel-titanium wire and an insulating layer made of insulating material covering one end of the nickel-titanium wire; it also includes a vacuum chamber and a processing device mounted on the vacuum chamber, the processing device comprising: The rotating seat is rotatably positioned inside the vacuum chamber. The clamping mechanism is mounted on the rotating base and is used to clamp and position the nickel-titanium wire. Vacuum pumping mechanism, used to evacuate the vacuum chamber; The spraying mechanism is connected to the vacuum chamber and is used to spray gaseous insulating material onto one end of the nickel-titanium wire, so that the insulating material covers one end of the nickel-titanium wire to form an insulating layer. A curing mechanism is used to cure the insulating layer.

[0006] By adopting the above technical solution, an insulating layer is formed by covering one end of the nickel-titanium wire with insulating material. Therefore, when the nickel-titanium wire is used, the electrosurgical contact also contacts the insulating layer, thereby reducing the risk of the nickel-titanium wire being cut and reducing the risk of medical accidents.

[0007] The nickel-titanium wire is placed on the rotating seat, the clamping mechanism clamps and positions the nickel-titanium wire, the vacuuming mechanism is activated to evacuate the vacuum chamber, the spraying mechanism is activated to spray gaseous insulating material onto the nickel-titanium wire, and at the same time the rotating seat drives the nickel-titanium wire to rotate, so that the insulating material covers the nickel-titanium wire to form an insulating layer. The curing mechanism is activated to cure the insulating layer, thereby completing the covering and processing of the insulating layer, making the insulation layer production faster and of better quality, and further reducing the risk of medical accidents.

[0008] After vacuuming by a vacuuming mechanism, the insulation layer is free of bubbles, pinholes, impurities, etc., and the adhesion of the insulation layer is stronger and will not be affected by airflow. At the same time, it reduces the waste of gaseous insulation material and heat loss, resulting in higher processing efficiency and better results, as well as energy saving and environmental protection, and further reducing the risk of medical accidents.

[0009] Optionally, the spraying mechanism includes: The spray plate is slidably positioned inside the vacuum chamber along the direction close to or away from one end of the nickel-titanium wire. A spray tube is set on a spray plate and its axis coincides with the axis of the nickel-titanium wire and the axis of rotation of the rotating seat. Multiple spray holes are evenly arranged on the inner side wall of the spray tube around its own axis in both the circumferential and radial directions. A feeding assembly is connected to multiple spray holes, allowing gaseous insulating material to be sprayed out through these holes. The spray plate drives the spray tube closer to the nickel-titanium wire, with one end of the wire positioned inside the tube. The feeding assembly is activated, causing the gaseous insulating material to be sprayed out through the multiple spray holes while the wire rotates simultaneously. After spraying is complete, the feeding assembly stops outputting insulating material, the wire stops rotating, and the spray tube moves away from the wire, placing the wire outside the tube.

[0010] By adopting the above technical solution, the spray plate drives the spray tube to approach the nickel-titanium wire, so that the nickel-titanium wire is located inside the spray tube. The rotating seat drives the nickel-titanium wire to rotate, and the feeding component is activated to spray gas insulating material through multiple spray holes toward the nickel-titanium wire, forming an insulating layer on the outer surface of one end of the nickel-titanium wire. After the process is completed, the spray plate and the spray tube move away from the nickel-titanium wire, so that the nickel-titanium wire and the insulating layer are located outside the spray tube.

[0011] When the gaseous insulating material is ejected, it is located inside the ejection tube. The splashed insulating material can bounce back and accumulate on the surface of the nickel-titanium wire, greatly reducing the waste of insulating material and also reducing the risk of temperature drop on the surface of the nickel-titanium wire. Multiple ejection holes are located around the nickel-titanium wire, which makes the impact force on the nickel-titanium wire more even when the insulating material is ejected, reducing the risk of uneven insulation layer thickness due to the nickel-titanium wire tilting. The cooperation between multiple ejection holes and the rotation of the nickel-titanium wire can make the insulation layer production faster and more uniform, further reducing the risk of medical accidents.

[0012] Optionally, multiple nozzles cooperate to cover one end of the nickel-titanium wire sidewall and end face; multiple nozzles and rotating seats are spaced apart to allow multiple nickel-titanium wires to be processed simultaneously to obtain an insulating layer.

[0013] By adopting the above technical solution, the nickel-titanium wire is relatively soft. Although the impact force on the nickel-titanium wire is small, there is still a risk of deformation due to gravity during the rotation of the nickel-titanium wire. Multiple nozzles spray insulating material that moves towards the surface of the nickel-titanium wire and towards the end face of the nickel-titanium wire. This allows the insulating layer to better cover one end of the nickel-titanium wire, improving the insulation effect. At the same time, the force of the insulating material when impacting the nickel-titanium wire can support the end face of the nickel-titanium wire, reducing the risk of deformation of the nickel-titanium wire and further reducing the risk of medical accidents. In addition, multiple nozzles can process multiple nickel-titanium wires at the same time, improving processing efficiency and effect.

[0014] Optionally, the feeding assembly includes: A material bin and an additive, the additive being used to deliver insulating material into the material bin; Heating element, used to heat the insulating material in the material box and melt the insulating material into a liquid state; A vaporizer is used to convert liquid in a material tank into a gaseous state and connect it to a spray nozzle via a telescopic assembly.

[0015] By adopting the above technical solution, the additive adds insulating material to the material box in real time, the heating element is activated to heat and melt the insulating material in the material box to obtain liquid, the vaporizer is activated to convert the liquid into gas, and the gaseous insulating material is sprayed out through the telescopic component and the spray nozzle. The gaseous insulating material can be stopped after the vaporizer stops running; the telescopic component facilitates the movement of the spray plate and spray pipe to avoid obstruction.

[0016] Optionally, the telescopic component includes: A fixing pipe is installed on the spray pipe; A movable tube is mounted on the vaporizer and extends into the vacuum chamber. The movable tube is slidably mounted on the fixed tube and connects the vaporizer and the spray nozzle.

[0017] By adopting the above technical solution, the moving tube of the spray pipe moves on the fixed tube, thereby enabling the vaporizer and the spray hole to be connected before and after the spray pipe moves.

[0018] Optionally, the outer wall of the material box is covered with an insulation layer, which abuts against the vacuum box and causes the moving tube to pass through the material box, the connection between the insulation layer and the vacuum box in sequence, and then extend into the vacuum box.

[0019] By adopting the above technical solution, the insulation layer can insulate the material box, resulting in better insulation performance, better insulation layer processing quality, and energy saving and environmental protection. At the same time, by having the insulation layer and the vacuum box in contact with the insulation layer, the temperature of the insulation material inside the fixed tube is guaranteed, further improving the insulation layer processing efficiency and quality, and further saving energy and protecting the environment.

[0020] Optionally, an adjusting seat is vertically rotatably mounted inside the vacuum chamber, and the rotating seat is horizontally rotatably mounted on the adjusting seat. The adjusting seat rotates to align one end of the nickel-titanium wire with the spraying mechanism or the curing mechanism. The curing mechanism includes: The curing plate is slidably mounted on the vacuum chamber along the direction close to or away from the nickel-titanium wire; Hot air ducts and cold air ducts are mounted on a curing plate. The gas temperature emitted from the hot air duct is higher than that emitted from the cold air duct. The curing plate is close to the nickel-titanium wire, so that the insulating layer is located inside the hot air duct. Hot air is emitted from inside the hot air duct to the insulating layer for curing. The curing plate is then moved back, so that the insulating layer is located outside the hot air duct and the cold air duct is aligned with the insulating layer. Gas is emitted from the cold air duct to the insulating layer for cooling and curing.

[0021] By adopting the above technical solution, after the insulation layer on the nickel-titanium wire is processed, the nickel-titanium wire is located outside the spray tube. The adjusting seat drives the rotating seat and the nickel-titanium wire to align with the hot air pipe and the cold air pipe. The curing plate drives the hot air pipe to approach the nickel-titanium wire, so that the nickel-titanium wire is located inside the hot air pipe. The hot air pipe starts blowing hot air onto the nickel-titanium wire for curing. At the same time, the rotating seat rotates, driving the nickel-titanium wire to continue rotating, thereby achieving the curing of the insulation layer. Then the curing plate moves back, so that the nickel-titanium wire is located outside the hot air pipe, and the cold air pipe is aligned with the insulation layer. The cold air pipe blows air towards the insulation layer for cooling, thereby making the insulation layer processing more efficient and of better quality, which reduces the risk of medical accidents and improves processing efficiency and quality.

[0022] Optionally, the rotating base has an arc-shaped rotating groove for placing the nickel-titanium wire, and the clamping mechanism includes: The clamping plate is placed on the rotating seat; The clamping screw passes through the clamping plate and is threaded onto the rotating seat, so that the clamping plate presses against the nickel-titanium wire for positioning.

[0023] By adopting the above technical solution, the nickel-titanium wire is placed on the rotating groove, so that the nickel-titanium wire is located between the rotating groove and the clamping plate. The clamping screw is screwed to the rotating seat to position the clamping plate, thereby clamping the nickel-titanium wire. After the clamping screw is screwed to release the clamping plate, the nickel-titanium wire can be removed.

[0024] Optionally, the vacuuming mechanism includes: A vacuum pump, connected to the vacuum chamber and used to create a vacuum inside the vacuum chamber; A filter screen is installed on the vacuum chamber and is used to prevent insulating material from entering the vacuum pump. The control door is rotatably mounted on the vacuum chamber and is used to open or close the vacuum chamber; the adjustment seat drives multiple nickel-titanium wires to pass sequentially through the spraying mechanism, the curing mechanism and the control door before returning to the spraying mechanism.

[0025] By adopting the above technical solution, the control door facilitates the opening or closing of the vacuum chamber, thereby enabling the placement and removal of nickel-titanium wires; the vacuum pump is activated to evacuate the vacuum chamber, and the filter screen can prevent impurities from entering the vacuum pump; the adjusting seat drives multiple nickel-titanium wires to pass through the spraying mechanism, curing mechanism, and control door in sequence before returning to the spraying mechanism; thus, the space of the vacuum chamber can be better utilized, improving processing efficiency and quality.

[0026] Secondly, the processing method provided in this application adopts the following technical solution: A processing method, wherein a nickel-titanium wire is placed: the nickel-titanium wire is placed on a rotating seat, and a clamping mechanism clamps and positions the nickel-titanium wire; Processing the insulation layer: The adjusting seat drives the nickel-titanium wire to align with the spraying mechanism, the vacuuming mechanism evacuates the vacuum box, the spraying mechanism starts to spray gaseous insulating material onto the nickel-titanium wire, and at the same time the rotating seat drives the nickel-titanium wire to rotate, thereby completing the processing of the insulation layer; Curing: The adjusting seat drives the nickel-titanium wire to align with the hot air pipe, so that the nickel-titanium wire is inside the hot air pipe and hot air is blown onto the insulation layer for curing. When the hot air pipe moves away from the nickel-titanium wire, so that the nickel-titanium wire is outside the hot air pipe and cold air is blown onto the insulation layer for cooling. The adjusting seat returns to its original position, and then the above process is repeated.

[0027] By adopting the above technical solution, the nickel-titanium wire is placed on a rotating seat, and the clamping mechanism clamps and positions the wire. An adjusting seat drives the wire to align with the spraying mechanism, while a vacuuming mechanism evacuates the vacuum chamber. The spraying mechanism then sprays gaseous insulating material onto the wire, and simultaneously, the rotating seat drives the wire to rotate, thus completing the insulation layer processing. The adjusting seat then drives the wire to align with the hot air duct. The hot air duct is brought close to the wire, placing it inside the duct for hot air curing. Conversely, the hot air duct is moved away from the wire, placing it outside the duct for cooling. The adjusting seat returns to its original position, and the above process is repeated. This reduces the risk of medical accidents and improves processing efficiency and quality.

[0028] In summary, this application includes at least one of the following beneficial technical effects: 1. By covering one end of the nickel-titanium wire with insulating material to form an insulating layer, the risk of the nickel-titanium wire being cut is reduced. The nickel-titanium wire is installed on the rotating base, the vacuuming mechanism is activated to draw a vacuum, the spraying mechanism is activated to spray gaseous insulating material onto the nickel-titanium wire, and at the same time the rotating base drives the nickel-titanium wire to rotate, so that the insulating material covers the nickel-titanium wire to form an insulating layer. The curing mechanism is activated to cure the insulating layer, thereby completing the covering and processing of the insulating layer. This makes the insulation layer production faster and of better quality, further reducing the risk of medical accidents.

[0029] 2. After vacuuming by a vacuuming mechanism, the insulation layer is free of bubbles, pinholes, impurities, etc., and the adhesion of the insulation layer is stronger and will not be affected by airflow. At the same time, it also reduces the waste of gaseous insulation materials and heat loss, resulting in higher processing efficiency and better results, achieving energy saving and environmental protection, and further reducing the risk of medical accidents.

[0030] 3. When the gaseous insulating material is ejected, it is located inside the ejection tube. The splashed insulating material can bounce back and accumulate on the surface of the nickel-titanium wire, greatly reducing the waste of insulating material and also reducing the risk of temperature drop on the surface of the nickel-titanium wire. Multiple ejection holes are located around the nickel-titanium wire, which makes the impact force on the nickel-titanium wire more even when the insulating material is ejected, reducing the risk of uneven insulation layer thickness due to the nickel-titanium wire tilting. The cooperation between multiple ejection holes and the rotation of the nickel-titanium wire can make the insulation layer production faster and more uniform, further reducing the risk of medical accidents.

[0033] The following provides a further detailed description of this application.

[0034] This application discloses a device for processing anti-cut positioning wires for lung nodule localization and detection.

[0035] Reference Figures 1-2 A device for processing anti-cut positioning wires for lung nodule localization detection includes a nickel-titanium wire 11 and an insulating layer 12 made of insulating material covering one end of the nickel-titanium wire 11; it also includes a vacuum chamber 13 fixedly installed on the ground and a processing device 2 set on the vacuum chamber 13. When the nickel-titanium wire 11 is in use, the insulating layer 12 is in contact with the electrosurgical knife, reducing the risk of the nickel-titanium wire 11 being cut. At the same time, the nickel-titanium wire 11 is placed in the vacuum chamber 13, and the processing device 2 processes the insulating layer 12 on one end of the nickel-titanium wire 11, which improves the processing quality and efficiency of the insulating layer 12, further reduces the risk of the nickel-titanium wire 11 being cut, reduces the risk of medical accidents, and improves processing efficiency and quality.

[0036] The insulating layer 12 is made of polyethylene terephthalate, which has excellent electrical insulation, excellent creep resistance and abrasion resistance. The insulating layer 12 also covers one sidewall and end face of the nickel-titanium wire 11.

[0037] Reference Figures 2-3The processing device 2 includes a rotating seat 21, a clamping mechanism 3, a vacuuming mechanism 4, a spraying mechanism 5, and a curing mechanism 8. A mounting frame 22 is fixed on the bottom wall of the vacuum chamber 13. An adjusting seat 23 is rotatably mounted on the upper surface of the mounting frame 22 via a vertical rotating shaft 1. A motor connected to the rotating shaft 1 is fixedly mounted on the bottom of the vacuum chamber 13. The motor is used to drive the adjusting seat 23 to rotate. The rotating seat 21 is rotatably mounted on the upper surface of the adjusting seat 23 via a horizontal rotating shaft 2. Multiple rotating seats 21 are spaced apart. Multiple motors connected to the rotating shaft 2 are fixedly mounted on the adjusting seat 23. Multiple motors are used to simultaneously drive multiple rotating seats 21 and multiple nickel-titanium wires 11 to rotate. At the same time, the rotation of two adjacent rotating seats 21 does not interfere with each other.

[0038] Reference Figures 1-4 Each rotating seat 21 is equipped with a clamping mechanism 3, which is used to clamp and position the nickel-titanium wire 11. The clamping mechanism 3 includes a clamping plate 31 and a clamping screw 32. Each rotating seat 21 has a horizontal rotating groove 33 on its upper surface for placing the nickel-titanium wire 11. The clamping plate 31 is placed on the upper surface of the rotating seat 21 and has a clamping groove 34 corresponding to the rotating groove 33. The clamping screw 32 passes through one end of the clamping plate 31 and is threadedly connected to the rotating seat 21, so that the clamping plate 31 presses against the nickel-titanium wire 11 for positioning. One end of the nickel-titanium wire 11 is placed horizontally on the rotating groove 33 and pushed to abut against the rotating groove 33 for positioning, so that the nickel-titanium wire 11 is also located on the clamping groove 34. The other end of the nickel-titanium wire 11 is located outside the rotating seat 21. Tightening the clamping screw 32 pushes the clamping plate 31 to press against the nickel-titanium wire 11 for positioning.

[0039] The vacuuming mechanism 4 is used to evacuate the vacuum chamber 13. The spraying mechanism 5 is connected to the vacuum chamber 13 and is used to spray gaseous insulating material onto one end of the nickel-titanium wire 11, so that the insulating material covers one end of the nickel-titanium wire 11 to form an insulating layer 12. The spraying mechanism 5 is started multiple times to spray gaseous insulating material, and the vacuuming mechanism 4 is started multiple times to evacuate the vacuum chamber 13 to different degrees. The start and stop times and number of times of the spraying mechanism 5 and the vacuuming mechanism 4 can be controlled as needed. The curing mechanism 8 is used to cure and cool the insulating layer 12. The curing mechanism 8 and the spraying mechanism 5 are located on both sides of the rotating seat 21 and the rotating groove 33, respectively.

[0040] The vacuum pumping mechanism 4 includes a vacuum pump 41, a filter screen, and a control door 43. The vacuum pump 41 is fixedly installed on the outer wall of the vacuum chamber 13 and communicates with the inside of the vacuum chamber 13. The filter screen is fixedly installed inside the vacuum chamber 13 and located at the connection between the vacuum pump 41 and the inside of the vacuum chamber 13. When the vacuum pump 41 is activated, it evacuates the vacuum chamber 13. The filter screen filters impurities and insulating materials and prevents them from entering the vacuum pump 41. The vacuum chamber 13 has mounting holes for the operator to clamp the nickel-titanium wire 11. The control door 43 is rotatably installed on the outer wall of the vacuum chamber 13 and abuts against the vacuum chamber 13 to seal the mounting holes. The control door 43 is positioned by a latch or lock. The latch and lock adopt existing technology structures, which will not be described in detail here.

[0041] The vacuum pump 41, the spraying mechanism 5, the curing mechanism 8, and the control door 43 are located in four different directions on the rotating seat 21 and the adjusting seat 23, so as to make better use of the space of the vacuum box 13. The adjusting seat 23 rotates to drive the nickel-titanium wire 11 to align with the spraying mechanism 5 to spray and form the insulating layer 12. The adjusting seat 23 drives the nickel-titanium wire 11 to align with the curing mechanism 8, and the curing mechanism 8 starts to cure the insulating layer 12. The adjusting seat 23 drives the nickel-titanium wire 11 to align with the control door 43, the control door 43 opens the mounting hole, the clamping mechanism 3 unlocks, the nickel-titanium wire 11 is replaced, and the control door 43 closes the mounting hole. The adjusting seat 23 drives the nickel-titanium wire 11 to continue to rotate to align with the spraying mechanism 5, and repeats the above steps to complete the processing of the insulating layer 12 on the nickel-titanium wire 11.

[0042] Reference Figures 2-5 The spraying mechanism 5 includes a spraying plate 51, a spraying tube 52, and a feeding assembly 6. The spraying plate 51 is horizontally slidably mounted on the upper surface of the mounting frame 22 and the sliding direction is towards or away from the rotating seat 21. Multiple spraying tubes 52 are spaced apart and correspond to multiple nickel-titanium wires 11. The spraying tubes 52 and the nickel-titanium wires 11 are coaxially arranged. One end of the spraying tube 52 near the nickel-titanium wire 11 is open and the other end is closed. The movement of the spraying plate 51 drives the spraying tubes 52 to approach the nickel-titanium wires 11, so that multiple nickel-titanium wires 11 extend into the inner side of multiple spraying tubes 52 respectively. A driving component 44 is fixedly installed on the outer wall of the vacuum box 13, passing through the vacuum box 13 and connected to one end of the spraying plate 51. The driving component 44 can be an electric actuator or a cylinder.

[0043] Reference Figures 1-6Multiple spray holes 45 are spaced apart axially and radially along the inner wall of the spray tube 52. Multiple spray holes 45 are also provided on the inner wall of the sealed end of the spray tube 52. The feeding assembly 6 communicates with the multiple spray holes 45, allowing gaseous insulating material to be sprayed out through them. The spray plate 51 drives the spray tube 52 closer to the nickel-titanium wire 11, causing one end of the nickel-titanium wire 11 to extend into the spray tube 52. Simultaneously, the rotating seat 21 drives the nickel-titanium wire 11 to rotate, and the feeding assembly 6 is activated. The movement causes gaseous insulating material to be ejected through multiple nozzles 45, which spray the gaseous insulating material onto one side wall and end face of the nickel-titanium wire 11, forming an insulating layer 12 covering one side wall and end face of the nickel-titanium wire 11. After the insulating layer 12 is sprayed, the feeding assembly 6 stops outputting insulating material and the rotating seat 21 stops driving the nickel-titanium wire 11 to rotate. The spraying plate 51 moves to drive the spraying tube 52 away from the nickel-titanium wire 11, so that the nickel-titanium wire 11 is located outside the spraying tube 52.

[0044] The feeding assembly 6 includes a material box 61, an additive 62, a heating element 63, and a vaporizer 64. The outer wall of the material box 61 is covered with an insulation layer 67. The material box 61 is fixedly installed on the ground, and the insulation layer 67 is positioned against the outer wall of the vacuum box 13 near the spray pipe 52. The additive 62 includes an additive tube 65 and an additive hopper 66. The additive tube 65 passes vertically through the top of the material box 61 and extends into the material box 61. The additive hopper 66 is fixedly installed at the top of the additive tube 65, and the diameter of the top end is larger than the diameter of the bottom end. A control valve is provided on the additive tube 65 to control its opening and closing. The insulating material is in a solid granular state and is placed in the additive hopper 66. When the control valve is opened, the insulating material is continuously added to the material box 61. The heating element 63 is a heating tube fixedly installed in the additive box and is used to heat the insulating material, causing the insulating material to melt into a liquid.

[0045] The vaporizer 64 is fixedly installed inside the material box 61 and vaporizes the liquid insulating material after activation. The vaporizer 64 is connected to the spray hole 45 on the spray pipe 52 through the telescopic component 7. The telescopic component 7 is telescopic and adapts to the movement of the spray pipe 52. The telescopic component 7 includes a fixed pipe 71 and a moving pipe 72. The fixed pipe 71 includes multiple connecting parts 73 and a sliding part 74. The multiple connecting parts 73 are respectively provided with the multiple fixed pipes 71 and are fixedly connected to the fixed pipes 71 and connected to the spray hole 45. The moving pipe 72 is connected to the end of the multiple connecting parts 73 away from the fixed pipe 71, and the sliding part 74 is located at the end of the spray plate 51 away from the driving member 44. At the same time, the sliding part 74 is opened along the moving direction of the spray plate 51 and is located inside the vacuum box 13.

[0046] The moving tube 72 is fixedly installed on the vaporizer 64, and the moving tube 72 passes through the material box 61, the insulation layer 67 near the vacuum box 13, and the connection between the insulation layer 67 and the vacuum box 13 before extending into the vacuum box 13. The sliding part 74 is slidably installed on the inner wall of the moving tube 72. When the vaporizer 64 is started, the liquid insulating material in the material box 61 is converted into a gaseous state. The gaseous insulating material passes through the moving tube 72, the sliding part 74, and multiple connecting parts 73, and is then sprayed towards the nickel-titanium wire 11 through multiple spray holes 45.

[0047] The curing mechanism 8 includes a curing plate 81, a hot air duct 82, and a cold air duct 83. The curing plate 81 is slidably mounted on the mounting frame 22 along the moving direction of the spray plate 51, and the curing plate 81 and the spray plate 51 are respectively located on both sides of the adjusting seat 23. A pushing component 84 connected to the curing plate 81 is fixedly mounted on the outer wall of the vacuum box 13. The pushing component 84 can be an electric push rod or a cylinder, used to drive the curing plate 81 to move. The hot air duct 82 is fixedly mounted on the curing plate 81. There are multiple hot air ducts 82 and cold air ducts 83 that extend at intervals and are arranged correspondingly to each other. Multiple hot air ducts 82 correspond to multiple nickel-titanium wires 11. The hot air ducts 82 are in a horizontal state and are coaxially arranged with the nickel-titanium wires 11.

[0048] The cold air duct 83 is fixedly installed on the upper surface of the hot air duct 82. The end of the cold air duct 83 near the adjusting seat 23 is inclined downward. Multiple ventilation holes are spaced apart on the inner sidewalls of both the hot air duct 82 and the cold air duct 83. Both the hot air duct 82 and the cold air duct 83 blow gas toward the insulation layer 12 through the ventilation holes. The temperature of the gas blown out by the hot air duct 82 is higher than that of the gas blown out by the cold air duct 83. The temperature of the gas blown out by the hot air duct 82 can be 120°C, so as to achieve the curing of the insulation layer 12. The cold air duct 83 blows out cold air to cool and cure the insulation layer 12.

[0049] The adjusting seat 23 drives the rotating seat 21 and multiple nickel-titanium wires 11 to rotate 180 degrees, so that the multiple nickel-titanium wires 11 are aligned with multiple spray tubes 52 to spray material to form an insulating layer 12. The adjusting seat 23 continues to rotate 90 degrees, so that the multiple nickel-titanium wires 11 are aligned with multiple hot air tubes 82. The hot air tubes 82 are close to the nickel-titanium wires 11 and the insulating layer 12 is located inside the hot air tubes 82. Hot air is sprayed from inside the hot air tubes 82 to the insulating layer 12 for curing. The cold air tube 83 is closed.

[0050] The hot air duct 82 shuts off the jet, the curing plate 81 moves back, and the insulating layer 12 is positioned outside the hot air duct 82, while the cold air duct 83 is aligned with the insulating layer 12. The cold air duct 83 sprays gas onto the insulating layer 12 for cooling and curing. The adjusting seat 23 continues to rotate 90 degrees, driving multiple nickel-titanium wires 11 to the control door 43. The control door 43 opens, and the operator turns the clamping screw 32 to loosen the clamping plate 31. After removing the nickel-titanium wire 11, a new nickel-titanium wire 11 is inserted. The clamping screw 32 is turned to clamp the multiple nickel-titanium wires 11. The above actions are repeated to complete the processing of the insulating layer 12 on the multiple nickel-titanium wires 11.

[0051] Both the hot air duct 82 and the cold air duct 83 are equipped with air supply components 9 that communicate with the ventilation holes. The following explanation will take the air supply component 9 that communicates with the hot air duct 82 as an example. The air supply component 9 includes multiple air inlet pipes 91, connecting pipes 92 and air supply pipes 93. The multiple air inlet pipes 91 are aligned with the multiple hot air ducts 82. The air inlet pipes 91 are fixedly connected to the hot air ducts 82 and communicate with the ventilation holes. The air supply pipes 93 are fixedly connected to the end of the multiple air inlet pipes 91 away from the hot air ducts 82 and are located at the end of the curing plate 81 away from the pusher 84.

[0052] The gas supply pipe 93 extends through the vacuum chamber 13 and into the vacuum chamber 13. The connecting pipe 92 is slidably installed on the inner wall of the gas supply pipe 93. A control valve is fixedly installed on the gas supply pipe 93 located on the outside of the vacuum chamber 13. When the control valve is opened, hot air passes through the air inlet pipe 91, the connecting pipe 92 and the gas supply pipe 93 and finally blows to the insulation layer 12 through the ventilation hole. At the same time, it can also accommodate the sliding of the curing plate 81. The control process of the cold air pipe 83 is the same as that of the hot air pipe 82.

[0053] The working principle of this application embodiment is as follows: The control door 43 is opened, the clamping screw 32 is turned to loosen the clamping plate 31, the nickel-titanium wire 11 is placed on the rotating groove 33, the nickel-titanium wire 11 is pushed against the rotating groove 33 for positioning, the clamping screw 32 is turned to push the clamping plate 31 against the nickel-titanium wire 11 for positioning, the control door 43 is closed, the vacuum pump 41 is started to evacuate the vacuum chamber 13; the adjusting seat 23 drives multiple nickel-titanium wires 11 to align with multiple spray tubes 52, the spray plate 51 drives multiple spray tubes 52 to approach the nickel-titanium wires 11, so that multiple nickel-titanium wires 11 are located in the spray tubes 52, the vaporizer 64 is started, the gaseous insulating material is sprayed onto the nickel-titanium wires 11 through multiple spray holes 45, and multiple rotating seats 21 drive multiple nickel-titanium wires 11 to rotate, thereby forming an insulating layer 12 on the nickel-titanium wires 11.

[0054] When the vaporizer 64 is closed, the rotating seat 21 stops rotating, and the spray pipe 52 moves away from the nickel-titanium wire 11, the multiple nickel-titanium wires 11 are located outside the spray pipe 52. The adjusting seat 23 drives the multiple nickel-titanium wires 11 to align with the multiple hot air pipes 82. The hot air pipes 82 are close to the nickel-titanium wires 11, and the multiple nickel-titanium wires 11 are located inside the multiple hot air pipes 82. The multiple rotating seats 21 drive the multiple nickel-titanium wires 11 to rotate, and hot air is blown towards the insulating layer 12 through the ventilation holes. The multiple hot air pipes 82 move away from the nickel-titanium wires 11, so that the multiple cold air pipes 83 are aligned with the insulating layer 12. The cold air cools the insulating layer 12. The adjusting seat 23 drives the multiple nickel-titanium wires 11 to the control door 43, and then repeats the process, thereby completing the processing of the insulating layer 12 on the nickel-titanium wires 11, reducing the risk of medical accidents, and improving processing efficiency and processing quality.

[0055] This application discloses a processing method.

[0056] Reference Figures 1-6 The processing method includes the following steps: Place the nickel-titanium wire 11: Place the nickel-titanium wire 11 on the rotating seat 21, and the clamping mechanism 3 clamps and positions the nickel-titanium wire 11. Processing the insulation layer 12: The adjusting seat 23 drives the nickel-titanium wire 11 to rotate and align with the spray tube 52. The vacuuming mechanism 4 evacuates the vacuum box 13. The spray tube 52 is close to the nickel-titanium wire 11, so that the nickel-titanium wire 11 is located inside the spray tube 52. The gaseous insulating material is sprayed onto the nickel-titanium wire 11. At the same time, the rotating seat 21 drives the nickel-titanium wire 11 to rotate, thereby completing the processing of the insulation layer 12. The spray tube 52 is moved away from the nickel-titanium wire 11, so that the nickel-titanium wire 11 is located outside the spray tube 52. Curing: The adjusting seat 23 drives the nickel-titanium wire 11 to align with the hot air pipe 82, so that the nickel-titanium wire 11 is inside the hot air pipe 82 and hot air is blown onto the insulating layer 12 for curing. The hot air pipe 82 moves away from the nickel-titanium wire 11, so that the nickel-titanium wire 11 is outside the hot air pipe 82 and cold air pipe 83 blows cold air onto the insulating layer 12 for cooling. The adjusting seat 23 returns to its original position, and then the above process is repeated.

[0057] The working principle of this application embodiment is as follows: The nickel-titanium wire 11 is placed on the rotating seat 21, and the clamping mechanism 3 clamps and positions the nickel-titanium wire 11; the adjusting seat 23 drives the nickel-titanium wire 11 to rotate and align with the spray pipe 52, the vacuuming mechanism 4 evacuates the vacuum box 13, and the gaseous insulating material is sprayed onto the nickel-titanium wire 11. At the same time, the rotating seat 21 drives the nickel-titanium wire 11 to rotate, thereby completing the processing of the insulating layer 12. The adjusting seat 23 drives the nickel-titanium wire 11 to align with the hot air pipe 82, blowing hot air onto the insulating layer 12 for curing, while the cold air pipe 83 blows cold air onto the insulating layer 12 for cooling. The adjusting seat 23 returns to its original position, and then the above process is repeated, which reduces the risk of medical accidents and improves processing efficiency and quality.

[0058] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
