Description

Technical Field

[0001] The present invention belongs to the technical field of beam protection devices, and specifically, it relates to a light guide beam end fixing device and a fixing method based on a breakwater protection method. Background Art

[0002] In many fields such as surgical operations, medical examinations, manufacturing, and industrial inspections, light guide beams play a crucial role. They can efficiently transmit light and meet the lighting requirements in various complex environments. However, the ends of light guide beams are extremely vulnerable to damage during actual use.

[0003] With the wide development and application of laparoscopic techniques, laparoscopic surgical instruments are of great significance for the smooth progress of medical work. The light guide beam can provide a very good light source for surgical operations and ensure the smooth progress of the surgery.

[0004] When using instruments in laparoscopic surgeries, it is often found that the light guide hose and the light guide beam are damaged, and the positions with the highest damage probability are the two head ends. Existing devices protect them through different methods. Currently, the relatively common method is to directly wrap and fix the head ends of the light guide beam with different items such as heat shrink tubes, tapes, plastics, etc. However, the corresponding methods cannot provide good protection for both ends of the light guide beam.

[0005] The above simple protection methods can only provide limited physical protection. When the two ends of the light guide beam are subjected to greater external forces, such as accidental violent operations by surgeons during surgery, etc., the beam is still difficult to avoid damage. These damages are likely to occur at the connection between the beam not protected by the protective sleeve and the protective sleeve, which has certain deficiencies. Moreover, the light guide beam is expensive. If the light guide beam is damaged, it needs to be repaired or replaced with a new one, which incurs huge costs, significantly increases the unit expenditure, and wastes national resources. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a light guide beam protection device that can overcome the above problems or at least partially solve the above problems.

[0007] To solve the above technical problem, we invented the device of the present invention by combining the principle of the slope breakwater that has been applied in clinical practice. The basic concept of the technical solution adopted by the present invention is: a light guide beam end fixing device based on a breakwater protection method, including a fixing shell. The fixing shell is a hollow housing, and openings for the beam to enter and exit are provided at both ends of the fixing shell. It further includes:

[0008] A sliding ring, slidably connected inside the fixing shell;

[0009] A rotating disk, rotatably connected inside the sliding ring. An empty opening coaxial with the opening is provided at the center of the rotating disk;

[0010] Two groups of telescopic rods are fixedly connected to the rotating disk, and the telescopic ends of the two groups of telescopic rods are arranged oppositely;

[0011] The pressure roller is rotatably connected to the telescopic end of the telescopic rod. Through the movement of the sliding ring and the rotation of the rotating disk, the pressure roller can roll out spiral shallow indentations on the light beam;

[0012] The adhesive tape is rotatably connected to the rotating disk;

[0013] The displacement sensor is fixedly connected in the fixed shell, and the displacement sensor is used to monitor the position of the rotating disk;

[0014] Through the movement of the sliding ring and the rotation of the rotating disk, the pressure roller continuously squeezes the light beam, generating spiral shallow indentations on the surface of the light beam, and simultaneously winding the adhesive tape on the indented light beam. The displacement sensor synchronously detects the length of the adhesive tape wound on the light beam. After the adhesive tape wound in the first layer reaches 16 cm, the adhesive tape is disconnected, and the sliding ring and the rotating disk are reset to perform the second layer of winding. The second layer is wound in a way that overlaps half of the first layer. When the length reaches 15 cm, the winding stops, and then the third layer and the fourth layer of adhesive tape are wound on this basis until a breakwater-shaped protective sleeve is finally formed, so that the radius of curvature of the light beam after bending is ≥0.050 m.

[0015] For the movement of the sliding ring, further, a second motor is fixedly connected in the fixed shell, a lead screw is fixedly connected to the output end of the second motor, a slide rail is fixedly connected in the fixed shell, the sliding ring is slidably connected to the slide rail, and the sliding ring is threadedly connected to the lead screw.

[0016] For the stable movement of the sliding ring, further, a limiting groove is provided on the sliding ring, and the limiting groove matches the slide rail.

[0017] For fixing the connector of the light beam, further, a first fixed airbag ring is connected in one opening of the fixed shell, an air pump is fixedly connected in the fixed shell, an air outlet pipe is connected to the air outlet end of the air pump, and the air outlet pipe is connected to the first fixed airbag ring.

[0018] For fixing the light beam and straightening the light beam at the same time, further, a moving frame is connected to the sliding ring, an empty opening coaxial with the opening is provided at the top of the moving frame, a second fixed airbag ring is connected in the empty opening, an air outlet pipe is connected to the air outlet end of the air pump, the second fixed airbag ring is connected to the air outlet pipe, pressure relief valves are provided on both the first fixed airbag ring and the second fixed airbag ring, and electronic valves are provided in both the air outlet pipe and the air outlet pipe.

[0019] To facilitate the rotation of the rotating disk, further, a first motor is fixedly connected to the sliding ring, a gear is fixedly connected to the output end of the first motor, a toothed ring is fixedly connected to the rotating disk, and the toothed ring is meshed with the gear.

[0020] To facilitate the temporary fixation of the light beam after the first layer of winding, further, the moving frame is slidably connected to the slide rail, an electromagnet one for fixing the moving frame is fixedly connected to the sliding ring, and an electromagnet two in contact with the slide rail is fixedly connected to the moving frame.

[0021] To facilitate the installation and replacement of the adhesive tape, further, a mounting disk is rotatably connected to the rotating disk, the adhesive tape is mounted on the mounting disk, and a locking clip is threadedly connected to the mounting disk.

[0022] To facilitate the use of the first air outlet pipe, further, a notch is provided on the sliding ring.

[0023] A fixing method for protecting the end of a light guide beam, used for a light guide beam end fixing device based on a breakwater protection method, includes the following steps:

[0024] Step 1: Pass one end of the light guide beam through the opening and the empty hole, and by starting the air pump, fix one end of the light guide beam with a connecting head through the fixing airbag ring one, and then close the air pump;

[0025] Step 2: Start the telescopic rod so that the pressure roller can squeeze the outer surface of the light guide beam;

[0026] Step 3: Start the first motor and the second motor, continuously squeeze the surface of the light guide beam to generate spiral indentations, then open the air pump to inflate the fixing airbag ring two to fix the light guide beam, and at the same time, the fixing airbag ring two moves synchronously to gradually tighten and straighten the light guide beam;

[0027] Step 4: Turn off the first motor and the second motor, stick one end of the adhesive tape on the surface of the light beam with indentations, and then start the first motor and the second motor again to continuously wrap the surface of the light guide beam with the adhesive tape;

[0028] Step 5: Detect the moving distance of the sliding ring through the displacement sensor. After the first layer reaches 16 cm, turn off the first motor and the second motor, reset the telescopic rod and cut off the adhesive tape. Finally, reverse the first motor to reset the sliding ring, and then wind the adhesive tape in a way that overlaps half on the basis of the first layer. Then start the first motor for the second layer of winding. The length of the second layer of winding is 1 cm less than the length of the first layer, which is 15 cm;

[0029] Step 6: Repeat Step 5 to successively wind the third layer and the fourth layer;

[0030] Step 7: Open the pressure relief valve and take out the light guide beam.

[0031] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: Through the setting of the pressing roller, the present invention can press spiral shallow indentations on the surface of the light guide beam. These indentations can change the stress of the light guide beam and facilitate the pasting of the adhesive tape. After pasting the adhesive tape in the shape of a sloping breakwater at both ends of the light guide beam, the forces received at both ends of the light guide beam can be gradually dispersed within a certain range, and will not be significantly fixed to another point, causing damage to the light guide beam in other parts, thereby reducing the damage to the light beam and facilitating the long-term use of the light guide beam.

[0042] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will, with reference to the accompanying drawings in the embodiments of the present invention, clearly and completely describe the technical solutions in the embodiments. The following embodiments are used to illustrate the present invention but not to limit the scope of the present invention.

[0043] Embodiment 1: Refer to Figure 1 , 2 , 3, 4, 5, 6, 8. A fixing device for the end of a light guide beam based on a breakwater protection method, comprising a fixed shell 1, and openings for the light beam to enter and exit are provided at both ends of the fixed shell 1. The device further comprises: a sliding ring 2, slidably connected inside the fixed shell 1; a rotating disk 3, rotatably connected inside the sliding ring 2, and an empty opening coaxial with the opening is provided at the center of the rotating disk 3; two groups of telescopic rods 301, fixedly connected to the rotating disk 3, and the telescopic ends of the two groups of telescopic rods 301 are arranged oppositely; a pressing roller 302, rotatably connected to the telescopic ends of the telescopic rods 301. Through the movement of the sliding ring 2 and the rotation of the rotating disk 3, the pressing roller 302 can roll out spiral shallow indentations on the light beam; an adhesive tape, rotatably connected to the rotating disk 3.

[0044] The displacement sensor 8 is fixedly connected in the fixed housing 1. The displacement sensor 8 is used to monitor the position of the rotating disk 3. Through the movement of the slip ring 2 and the rotation of the rotating disk 3, the pressure roller 302 continuously presses the light beam, and spiral shallow indentations are generated on the surface of the light beam by extrusion. At the same time, adhesive tape is wound around the indented light beam. The displacement sensor 8 synchronously detects the length of the adhesive tape wound on the light beam. After the adhesive tape wound in the first layer reaches 16 cm, the adhesive tape is disconnected, and the slip ring 2 and the rotating disk 3 are reset to perform the winding of the second layer. The second layer is wound in a way that overlaps half of the first layer. When the length reaches 15 cm, the winding stops. Then, on this basis, the adhesive tape of the third layer and the fourth layer is wound until a breakwater-shaped protective sleeve is finally formed. Since the light beam is generally placed in a coiled shape during storage, at this time, the position wrapped with the adhesive tape requires that the radius of curvature after the light beam is bent be ≥ 0.050 m. A second motor 501 is fixedly connected in the fixed housing 1. A lead screw 502 is fixedly connected to the output end of the second motor 501. A slide rail 101 is fixedly connected in the fixed housing 1. The slip ring 2 is slidably connected to the slide rail 101 and is threadedly connected to the lead screw 502. A limiting groove 201 is provided on the slip ring 2, and the limiting groove 201 matches the slide rail 101. A first fixed airbag ring 102 is connected to one of the openings of the fixed housing 1. An air pump 7 is fixedly connected in the fixed housing 1. An air outlet pipe 701 is connected to the air outlet end of the air pump 7, and the air outlet pipe 701 is connected to the first fixed airbag ring 102. A moving frame 6 is connected to the slip ring 2, and an empty opening coaxial with the opening is provided at the top of the moving frame 6.

[0045] A second fixed airbag ring 601 is connected to the empty opening. An air outlet pipe 702 is connected to the air outlet end of the air pump 7, and the second fixed airbag ring 601 is connected to the air outlet pipe 702. Pressure relief valves are provided on both the first fixed airbag ring 102 and the second fixed airbag ring 601, which facilitates the reset of the fixed airbag rings. Electronic valves are provided in both the air outlet pipe 701 and the air outlet pipe 702, which facilitates the directional transmission of gas. A first motor 401 is fixedly connected to the slip ring 2. A gear 402 is fixedly connected to the output end of the first motor 401. A toothed ring 403 is fixedly connected to the rotating disk 3, and the toothed ring 403 is meshed with the gear 402. A notch 202 is provided on the slip ring 2, and the notch 202 facilitates the installation of the air outlet pipe 701.

[0046] When this device is in use, such as Figure 1 , Figure 2As shown, at this time, first insert the light beam for laparoscopic surgery through the empty opening on a fixed shell 1, and then the light beam sequentially penetrates through a moving frame 6 and a rotating disk 3. Finally, the end with the connector is located within the empty opening of a fixed airbag ring 102. Subsequently, the air pump 7 can be started to inflate the fixed airbag ring 102 through an air outlet pipe 701. At this time, the fixed airbag ring 102 expands, and then fixes the connector with the light beam. As Figure 1 shown, at this time, a part of the connector will be located within the fixed shell 1, which is convenient for subsequent winding of the adhesive tape.

[0047] Subsequently, start the first motor 401 to move the sliding ring 2, and start the telescopic rod 301 to make the pressure roller 302 closely adhere to the light beam (the position where it closely adheres at this time is the connection position between the light beam and the connector), so that the pressure roller 302 squeezes the light beam, and indentations can be generated on the light beam (the extrusion force value of the pressure roller 302 on the rubber outer skin of the light beam surface should be within the range of 2 - 8 MPa to avoid damage to the interior of the light beam caused by excessive extrusion). Start the air pump 7 to inflate the fixed airbag ring 2 601 through an air outlet pipe 702 to achieve slight clamping of the light beam (at this time, it is necessary to manually hold the light beam to make it taut to avoid bending or twisting of the light beam, which is inconvenient for subsequent wrapping, and the clamping force at this time should not be too large, otherwise the connector will be pulled out from the fixed airbag ring 102). Subsequently, start the first motor 401 and the second motor 501. While the sliding ring 2 moves slowly, the rotating disk 3 rotates, and then spiral shallow indentations are generated on the surface of the light beam through the pressure roller 302 (the spiral shallow indentations can have gaps between the indentations, that is, in a non-close state). Then when the adhesive tape reaches the position of the connector and the light beam with indentations, that is, when the sliding ring 2 moves 30 mm, turn off the two motors, and then manually stick one end of the adhesive tape on the light beam with indentations (adopt a spiral wrapping method. Taking the light beam diameter of 10 mm and the adhesive tape width of 30 mm as an example, about 30 mm of axial movement can complete the spiral wrapping according to tight spiral winding without considering slight overlapping fine-tuning. The specific value needs to be recalculated according to the width of the adhesive tape and the diameter of the light beam). Then restart the two groups of motors. At this time, it is possible to first press the indentations on the light beam through the pressure roller 302, and then wind the surface of the light beam with indentations with the adhesive tape.

[0048] When the fixed airbag ring two 601 on the moving frame 6 moves, the fixed airbag ring two 601 can straighten the light beam. Since the light beam is generally coiled when stored, the light beam itself has a certain bending stress. At this time, straightening can stretch the light beam straight, avoiding the bending and twisting of the light beam and facilitating subsequent wrapping. At the same time, because the light beam has a certain bending stress, at this time, spiral shallow indentations are pressed on the surface of the light beam, which can change the bending stress to a certain extent, making it change from bending to axial stress. Moreover, the uneven surface will increase the friction, which is conducive to the subsequent winding of the adhesive tape.

[0049] When the length of the first layer of wrapping reaches 16 cm, the motor one 401 and the motor two 501 stop at this time, the telescopic rod 301 resets, the operator cuts the adhesive tape, and fits the end of the adhesive tape on the light beam. Subsequently, the motor one 401 rotates in reverse to move the sliding ring 2 back to the initial position. At this time, the moving frame 6 stays in place to fix the wire harness, and then the second layer of adhesive tape is wrapped. When wrapping the second layer, based on the first layer of adhesive tape, the key is to make the second layer of adhesive tape adhere to the joint of the first layer of spiral adhesive tape. Specifically, this means that the position of the second layer of adhesive tape starts at half of the width of the first layer of adhesive tape, so as to accurately cover the second layer of adhesive tape on the joint of the first layer of spiral adhesive tape, ensuring the standardization and stability of the wrapping effect. Then, at this time, the spiral indentations can continue to be pressed on the surface of the first layer of adhesive tape through the pressure roller 302, or the indentations can not be pressed, and only the second layer of adhesive tape is wound.

[0050] After the second layer reaches 15 cm, according to the previous steps, the third layer is wrapped, and then the fourth layer is wrapped. Generally, only four layers are needed, and the number of wrapping layers can be increased according to requirements. After the wrapping is completed, a protective tube in the shape of a breakwater should be formed on the surface of the light beam. After being fixed by the breakwater method, the forces received at both ends of the light guide beam will be gradually dispersed within a certain range and will not be significantly fixed to another point, causing damage to the light guide beam in other parts.

[0051] After being fixed by the breakwater method, the forces received at both ends of the light guide beam will be gradually dispersed within a certain range and will not be significantly fixed to another point, causing damage to the light guide beam in other parts. Compared with the traditional direct wrapping, the bending force can be dispersed, further reducing the possibility of damage to the light guide beam and facilitating the long-term use of laparoscopic surgical instruments.

[0052] This device is not limited to the protection of the light guide beam for laparoscopic surgery. For various types of wire harnesses, at the port, the breakwater method can be used for fixation.

[0053] When the light beam is not in use, it is generally stored in a coiled shape. According to the requirement that the minimum diameter of the coiled circle during storage of the light beam is 10 cm, after protecting and fixing the two ends of the interface, the radius of curvature (R) of each point at both ends of the light guide beam is not less than 0.050 m.

[0054] Specifically, the first layer of wrapping of 16 cm is just an example. The flexibility of light guide beams from different manufacturers and brands varies, so it is impossible to specify the exact distance. However, the radius of curvature should be maintained at not less than 0.050 m.

[0055] Specifically, electrical tape should be used.

[0056] Among them, various distance information is judged by the distance sensor 8. A warning light can be installed on this device, or semi-automatic control can be adopted. After inputting a preset value, such as 16 cm, it stops running when it moves to the 16 cm side, and manual auxiliary control is required.

[0057] Example 2: Refer to Figure 5 、 6 A fixing device for the end of a light guide beam based on a breakwater protection method is basically the same as that in Example 1. Furthermore: The moving frame 6 is slidably connected to the slide rail 101. An electromagnet 602 for fixing the moving frame 6 is fixedly connected to the sliding ring 2. An electromagnet 603 in contact with the slide rail 101 is fixedly connected to the moving frame 6.

[0058] When fixing the moving frame 6, the power supply to the electromagnet 602 is disconnected, and power is supplied to the electromagnet 603. Subsequently, the separation of the moving frame 6 from the sliding ring 2 is achieved, and the moving frame 6 is fixed, facilitating the fixing of the light beam.

[0059] Example 3: Refer to Figure 7 A fixing device for the end of a light guide beam based on a breakwater protection method is basically the same as that in Example 2. Furthermore: A mounting disc 303 is rotatably connected to the rotating disc 3. The electrical tape is installed on the mounting disc 303. A locking clip 304 is threadedly connected to the mounting disc 303.

[0060] Through the setting of the mounting disc 303, it is convenient for the installation and disassembly of the electrical tape.

[0061] Example 4: Refer to Figure 1 、 2 、3, 4, 5, 6, 7, 8, A fixing method for protecting the end of a light guide beam, for a fixing device for the end of a light guide beam based on a breakwater protection method, includes the following steps:

[0062] Step 1: Pass one end of the light guide beam through the opening and the empty opening, and by starting the air pump 7, fix one end of the light guide beam with a connector through the fixed airbag ring 102, and then turn off the air pump 7;

[0063] Step 2: Start the telescopic rod 301 so that the pressure roller 302 can squeeze the outer surface of the light guide beam;

[0064] Step 3: Start the first motor 401 and the second motor 501 to continuously squeeze the surface of the light guide beam to generate spiral indentations. Then open the air pump 7 to inflate the fixed airbag ring 2 601 to fix the light guide beam. At the same time, the fixed airbag ring 2 601 moves synchronously to gradually tighten and straighten the light guide beam;

[0065] Step 4: Turn off the first motor 401 and the second motor 501, stick one end of the adhesive tape on the surface of the light guide beam with indentations, and then start the first motor 401 and the second motor 501 again to continuously wrap the surface of the light guide beam with the adhesive tape;

[0066] Step 5: Detect the moving distance of the sliding ring 2 through the displacement sensor 8. After the first layer reaches 16 cm, turn off the first motor 401 and the second motor 501, reset the telescopic rod 301 and cut off the adhesive tape. Finally, reverse the first motor 401 to reset the sliding ring 2, and then wind the adhesive tape in a way that overlaps half on the basis of the first layer. Then start the first motor 401 for the second layer winding. The length of the second layer winding is 1 cm less than the length of the first layer, which is 15 cm;

[0067] Step 6: Repeat Step 5 to perform the winding of the third layer and the fourth layer in sequence;

[0068] Step 7: Open the pressure relief valve and take out the light guide beam.

[0069] Through the setting of the pressure roller 302 in the present invention, spiral shallow indentations can be pressed on the surface of the light guide beam. These indentations can change the stress of the light guide beam and facilitate the sticking of the adhesive tape. After sticking the adhesive tape in the shape of a sloping breakwater at both ends of the light guide beam, the forces received at both ends of the light guide beam can be gradually dispersed within a certain range, and will not be significantly fixed to another point, causing damage to the light guide beam at other parts. In this way, the damage to the light guide beam can be reduced, facilitating the long-term use of the light guide beam.

[0070] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of the present invention can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content prompted above within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the present invention.
