Description

Technical Field

[0001] The present application relates to the field of nail magazine stapling, and in particular to a nail magazine stapling production device with an anti-leakage nail detection function. Background Art

[0002] In modern medical surgery, staplers play a vital role. The assembly quality of titanium staples in their stapler magazines directly affects the use effect of staplers in surgery and the patient's postoperative recovery. However, the traditional stapler magazine production method has many problems that need to be solved:

[0003] In the past, nailing was mostly done manually, with workers having to pick up titanium nails one by one and put them into the nail magazine. This was slow and labor-intensive, making it difficult to meet the needs of large-scale production. Even if some automated manipulators were used for nailing, the process still involved a single nail being installed one by one into a single nail magazine. There were many pauses and waiting times during the nailing process, resulting in low overall production efficiency and an inability to meet the growing market demand.

[0004] After stapling is completed, most traditional equipment cannot effectively detect whether there are missing nails in a timely manner. This makes it possible for some products with stapling defects to flow into subsequent processes and even eventually enter the market, posing serious quality risks to medical safety. Even if there are some detection methods, there are often problems such as inaccurate detection and poor timeliness, making it difficult to truly guarantee the product's pass rate.

[0052] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0053] Embodiment 1:

[0054] The present invention provides a nail magazine stapling production equipment with a nail leakage prevention detection function, please refer to Figure 1 - Fig.17 , mainly composed of a frame 1, a stapling conveyor belt 11, a jig 2, a stapling box 3, a stapling roller 4, a driving mechanism 6, a feeding transfer mechanism 5 and a pushing mechanism 9. Each component cooperates with each other to complete the efficient and accurate stapling operation and the anti-missing nail detection function. The following is a detailed introduction:

[0055] See also Figure 1 , as the basic framework of the entire equipment, the frame 1 is welded with high-strength steel and has sufficient strength and rigidity to withstand various forces generated during the operation of the equipment, ensuring the overall stability of the equipment structure and preventing deformation or displacement due to vibration, uneven force and other factors. Its dimensions are designed according to the actual production site and production scale, and sufficient space is reserved for the installation and maintenance of other components, which is convenient for operators to perform equipment commissioning, maintenance and material replenishment.

[0056] See also Figure 1 - Figure 2 The stapling conveyor belt 11 is horizontally installed on the frame 1, and is driven by a driving system composed of a motor, a reducer and a transmission belt to achieve uniform rotation, and is used to transport the jig 2 placed thereon. It should be noted that the conveyor belt is made of wear-resistant, corrosion-resistant rubber or polyurethane material with a certain friction force, and a number of jigs 2 are evenly fixed on the surface at equal intervals. The jig 2 is connected to the conveyor belt through positioning structures such as card slots and positioning pins, which can firmly fix the nail box 3 to be nailed, ensuring that the nail box 3 is always in an accurate predetermined position during the movement with the conveyor belt, providing a stable foundation for subsequent stapling operations.

[0057] See also Figure 3 Racks 21 are fixedly arranged on both sides of the jig 2. The racks 21 extend along the length direction of the jig 2. The parameters such as tooth shape and tooth pitch are precisely processed to have high precision and high strength. The main structure of the jig 2 is manufactured by aluminum alloy stamping process, which can withstand certain impact force and pressure, ensuring that it will not be deformed or damaged during long-term use, thereby stably fixing the nail box 3.

[0058] It should be noted that the stapler magazine 3 is a key component of the stapler, and three staple magazine groups are symmetrically and regularly arranged on both sides of the top. Each staple magazine group contains a plurality of equidistantly arranged staple magazines 31, and the stapler magazines 31 of adjacent staple magazine groups are arranged in a staggered manner, so that the stapler can ensure the staggered airtightness of the incision during stapling during use.

[0059] The present invention is directed to the arrangement of existing nail magazine groups, taking into account the continuity of the stapling operation and the positional correspondence between the titanium nails 7 on the stapling roller 4 and the nail magazine 31, so that the titanium nails 7 can be loaded into the corresponding nail magazine 31 in an orderly and efficient manner, avoiding stapling interference or omission.

[0060] For details, please refer to Figure 4 - Fig.13 The stapling roller 4 is mounted on the frame 1 and is located at a suitable position above the stapling conveyor belt 11 . Its main body is a cylindrical structure, and docking holes 42 are evenly opened on the surface and are strictly corresponding to the stapling bins 31 .

[0061] It should be noted that the docking hole 42 is finely machined using a multi-axis machine tool to control the tolerance of the size, shape and position of the docking hole 42 within the design range to adapt to the installation of the fixing nail sleeve 8 and ensure that the titanium nail 7 can be accurately positioned therein.

[0062] See also Figure 4 - Figure 8 A nail sleeve 8 is fixedly installed in the docking hole 42. The nail sleeve 8 is made of high-strength, wear-resistant and elastic engineering plastic such as polyetheretherketone (PEEK), and is connected to the docking hole 42 by interference fit. The nail sleeve 8 is used to reliably fix the titanium nail 7 and provide temporary storage and positioning guarantees for the titanium nail 7 during the stapling process to prevent the titanium nail 7 from loosening or shifting before the stapling operation is performed.

[0063] Both ends of the stapling roller 4 are provided with synchronous gears 41 meshing with the racks 21 on the jig 2. The number of teeth of the synchronous gear 41 is precisely set to be equal to twice the number of nail bins 31 on a single nail bin group, and the number of nail bins 31 on each single nail bin group is clearly an odd number. Through this specific matching relationship between the number of teeth and the number of nail bins, and the high-precision meshing transmission between the racks 21 and the synchronous gear 41, the stapling roller 4 can accurately rotate following the displacement of the jig 2 on the stapling conveyor belt 11, ensuring that the rotation angle of the stapling roller 4 and the moving position of the jig 2 always maintain strict correspondence, thereby ensuring that each titanium nail 7 can be accurately loaded into the corresponding nail bin 31, achieving precise stapling, and effectively avoiding quality problems such as stapling misalignment caused by synchronization errors.

[0064] See also Figure 5 - Figure 8 Specifically, in order to facilitate the loading of the titanium nail 7, the bottom of the nail magazine 31 is provided with an assembly clamping groove 311 for clamping the titanium nail 7, and a through groove is provided in the nail fixing sleeve 8. Both sides of the through groove are provided with nail fixing clamping grooves 82 corresponding to the nail feet of the titanium nail 7. The nail fixing clamping groove 82 is a V-shaped open groove structure. The side of the nail fixing clamping groove 82 close to the stapling roller 4 is fixed with an elastic convex point 81, and the elastic convex point 81 conflicts with the bending part of the titanium nail 7;

[0065] When the titanium nail 7 needs to be loaded into the empty nail sleeve 8 on the top of the stapling roller 4, the titanium nail 7 is pushed upward by the pushing mechanism 9 so that the nail body of the titanium nail 7 enters the through groove, and the elastic protrusion 81 is used to limit the position, and the nail foot of the titanium nail 7 is limited by the nail clamping groove 82, so that the empty nail sleeve 8 is loaded with the titanium nail 7 and the positioning accuracy is maintained;

[0066] When it is necessary to unload the nail sleeve 8 carrying the titanium nail 7 at the bottom of the nailing roller 4, the pushing mechanism 9 is also used to push the titanium nail 7 downward. Due to the rotation of the nailing roller 4, the nail feet of the titanium nail 7 in the nail sleeve 8 at the bottom are set upward, which meets the correct orientation of the titanium nail 7 in the nail magazine 31. As the pushing mechanism 9 pushes, the nail body of the titanium nail 7 squeezes the elastic protrusion 81 to deform it, thereby moving the titanium nail 7 downward from the nail sleeve 8 and pushed into the nail magazine 31, and fixed by the assembly clamp groove 311.

[0067] For further information, see Figure 8 A first detection contact 821 is also fixed in the nail clamping groove 82. Two groups of first detection contacts 821 are used to perform conductive detection on the titanium nail 7 in the nail sleeve 8 to determine whether there is a nail leakage phenomenon in the nail sleeve 8.

[0068] For further information, see Figure 9-13 The driving mechanism 6 is fixed on the frame 1 through a stable bracket 61 and is located on the inner side of the stapling roller 4 to form a rotational connection with the stapling roller 4 to ensure that the stapling roller 4 can rotate flexibly.

[0069] The upper and lower sides of the driving mechanism 6 are equipped with pushing mechanisms 9. The pushing mechanisms 9 on the upper and lower sides of the driving mechanism 6 cooperate with each other in structure and function, and are respectively used for pushing operations of the titanium nail 7 at different stages.

[0070] The top area of ​​the driving mechanism 6 is provided with six nail supply holes 64 arranged in the vertical direction, and the six nail supply holes 64 are reasonably arranged in a three-by-three manner to form a stable and symmetrical layout; similarly, its bottom area is also provided with six nail binding holes 63 arranged in the vertical direction, and the six nail binding holes 63 are also arranged in three-by-three manner, and the arrangement spacing of the nail binding holes 63 or nail supply holes 64 on the same side is strictly equal to the arrangement spacing of the nail magazine group on the same side.

[0071] This structural design ensures that the pushing mechanism 9 can accurately correspond to each nail magazine 31 when performing the titanium nail 7 pushing operation, ensuring that the titanium nail 7 can accurately fall into the corresponding nail magazine 31 after passing through the pushing mechanism 9 from the nail supply hole 64, thereby achieving efficient and accurate stapling operations and improving the success rate of stapling and overall production efficiency.

[0072] The driving mechanism 6 is fixedly mounted with a driving motor 62 at both ends. The driving motor 62 uses a high-precision, high-torque servo motor, which has precise speed and torque control functions and can be flexibly adjusted according to actual stapling requirements. The output end of the driving motor 62 is fixedly connected with three groups of cams 601. The cams 601 are driven by the driving motor 62, and the cams 601 rotate 180° when the stapling roller 4 moves one side of the tooth pitch. The arrangement spacing between adjacent cams 601 is precisely set to be equal to the arrangement spacing of the stapling holes 63 or the stapling holes 64, and the cam 601 in the middle is arranged symmetrically with the other two cams 601, which rotate 180° around the rotation axis of the driving motor 62.

[0073] The cam 601 is driven to rotate by the driving motor 62, and the rotational motion is converted into a linear reciprocating motion of the pushing bar 91 by utilizing the interaction between the cam 601 and the arc-shaped pressure-bearing portion 911 of the pushing mechanism 9, so that the pushing bar 91 can perform a pushing operation according to the set rhythm and stroke, thereby realizing the orderly and regular pushing operation of the titanium nail 7 by the pushing mechanism 9, ensuring the stability of the stapling process and avoiding stapling quality problems caused by unstable power or irregular pushing.

[0074] For details, please refer to Fig. 9 - Fig.11 The pushing mechanism 9 is installed in the nailing hole 63 and the nail supply hole 64 of the driving mechanism 6, and is specifically composed of a pushing bar 91 and a detection slider 95 and other components, which together realize the orderly pushing of the titanium nails 7 in the nailing roller 4 and the secondary detection function during the nailing process, further ensuring the accuracy of nailing and effectively avoiding the occurrence of missing nails.

[0075] The main body of the push bar 91 is a long metal structure, which is limitedly slidably connected to the internal space of the nail hole 63 or the nail supply hole 64. By arranging limit sliders or guide rail structures on both sides of the push bar 91 that cooperate with the inner walls of the nail hole 63 or the nail supply hole 64, stable linear sliding is achieved to prevent deflection or jamming.

[0076] The two ends of the push bar 91 are respectively fixed with limit slides 92, and the diameter, length and other dimensions of the limit slides 92 match the limit slots provided on the driving mechanism 6, ensuring that the push bar 91 can maintain stability and not shake excessively during the sliding process. A first tensioning spring 93 is clamped between the limit slide 92 and the limit slot, and the first tensioning spring 93 is made of spring steel wire, providing a reliable reset elastic force for the push bar 91, ensuring that the push bar 91 can automatically return to the initial position after completing a push action, so as to perform the next push operation, and ensure the continuity and repeatability of the push action. An arc-shaped pressure-bearing portion 911 is provided at one end of the pushing strip 91 away from the stapling roller 4. The arc-shaped surface of the arc-shaped pressure-bearing portion 911 is polished to reduce the friction with the driving component. It is used to receive the external driving force and convert it into its own pushing force. The other end of the pushing strip 91 close to the stapling roller 4 is provided with an arc-shaped pushing portion 912. The shape of the arc-shaped pushing portion 912 is adapted to the shape of the nail body of the titanium nail 7, and it directly contacts the nail body of the titanium nail 7, thereby effectively transmitting the pushing force to the titanium nail 7, realizing the position movement of the titanium nail 7 inside the device, and ensuring that the titanium nail 7 can be pushed to the corresponding position according to the predetermined direction and force.

[0077] The detection slider 95 is a block-shaped structure as a whole, and is limitedly slidably connected to the push bar 91. By setting a guide groove and a guide rail structure between the detection slider 95 and the push bar 91, it can slide flexibly along the push bar 91, and a second tensioning spring 94 is clamped between the two. The second tensioning spring 94 is made of a spring material with a designed elastic coefficient to ensure the flexible sliding and resetting performance of the detection slider 95, so that it can remain in the initial position when not disturbed by external forces, and can slide accordingly when subjected to external forces such as squeezing of the titanium nail 7 and reset after the force disappears. Two groups of symmetrically distributed second detection contacts 951 are provided on one side of the detection slider 95 close to the stapling roller 4. The second detection contacts 951 accurately correspond to the nail feet of the titanium nail 7 and are made of highly sensitive conductive material. Through this structural design of the pushing mechanism 9, not only can the orderly pushing of the titanium nail 7 in the equipment be achieved, but also secondary detection can be performed during the stapling process. For example, when the titanium nail 7 is pushed into the nail fixing sleeve 8 at the top of the stapling roller 4, the second detection contact 951 contacts the nail foot of the pushed titanium nail 7 using the second tensioning spring 94. If the detection instrument detects that there is electrical conductivity between the second detection contacts 951, it proves that the titanium nail 7 is on the correct pushing path. Otherwise, it indicates that there may be a pushing abnormality or a missing titanium nail 7. Early warning can be given to further ensure the accuracy of stapling, effectively avoid the occurrence of missing nails, and improve product quality.

[0078] For further information, see Figure 14-17The feeding transfer mechanism 5 is symmetrically arranged at both ends of the driving mechanism 6. Its overall structure is compact and its functional integration is high. It is mainly used to orderly and continuously provide titanium nails 7 to the nail fixing sleeve 8 at the top of the stapling roller 4 to ensure that the stapling operation will not be interrupted due to insufficient material supply.

[0079] The feeding transfer mechanism 5 includes a base plate 51, a guide rod group 52, a cutting mechanism 53 and a synchronous belt 54, wherein the base plate 51 is made of high-strength metal plate and serves as the basic supporting component of the entire feeding transfer mechanism 5, providing a stable installation foundation for other components. Its surface is smoothed and is provided with multiple mounting holes and positioning pin holes for fixing other components, ensuring that the installation position of each component is accurate and the connection is firm, thereby ensuring the structural stability of the entire feeding transfer mechanism 5 during operation.

[0080] The guide rod group 52 is fixedly installed at the top position of the side of the base plate 51 away from the driving mechanism 6, and is composed of two parallel and spaced guide rods. The surface of the guide rod is smooth and the spacing between the two guide rods is equal to the spacing between the two bends of the titanium nail 7. It is used to guide the titanium nail 7 in an orderly manner so that it is arranged in a predetermined direction and position, thereby preparing for subsequent stapling operations, ensuring that the titanium nail 7 can smoothly enter the stapling process, and avoiding confusion, blockage, etc. in the transportation process of the titanium nail 7.

[0081] The cutting mechanism 53 is arranged inside the guide rod group 52 and driven by a servo motor. The servo motor is connected to the transmission component of the cutting mechanism 53 through a high-precision coupling, and can perform precise reciprocating motion according to a preset program and rhythm. The main function of the cutting mechanism 53 is to cut and separate the titanium nails 7 continuously conveyed on the guide rod group 52 according to the stapling requirements. The cutting action is achieved by a special tool or a clamping claw structure to ensure that the quantity and state of the titanium nails 7 provided to the stapling process each time can meet the requirements, ensure the continuity and accuracy of the stapling operation, and avoid affecting the stapling quality due to inaccurate supply quantity or poor state of the titanium nails 7.

[0082] The synchronous belt 54 is arranged on one side of the base plate 51 close to the driving mechanism 6. There are two groups of synchronous belts 54 symmetrically arranged. They are made of high-strength polyurethane material and have a steel wire core or fiber core inside to enhance their tensile strength and wear resistance. They are driven by a stepper motor to achieve stable operation, and the transmission accuracy and stability of the synchronous belt 54 are ensured by means of precise synchronous pulleys and tensioning devices. A number of equally spaced mating grooves 541 are arranged on the synchronous belt 54. The arrangement spacing of the mating grooves 541 is precisely set to be equal to the arrangement spacing of the nail supply holes 64. At the same time, the spacing between the adjacent mating grooves 541 of the two groups of synchronous belts 54 is equal to the width of the titanium nail 7. Through such a structural design, the titanium nail 7 separated by the cutting mechanism 53 can be accurately transported to the position accurately corresponding to the nail supply hole 64 of the driving mechanism 6, realizing efficient transfer and supply of materials, ensuring that the entire stapling operation can be carried out smoothly and efficiently, and reducing stapling delays or errors caused by inaccurate material transportation.

[0083] In addition, the frame 1 is also equipped with a vibrating feeder 12 for stably providing titanium nails 7 to the guide rod group 52. The vibrating feeder 12 arranges the titanium nails 7 in a specific direction and order through the vibration generated by itself, and continuously delivers them to the guide rod group 52, providing a continuous and stable supply of raw materials for the entire stapling production equipment. The vibrating feeder 12 is equipped with components such as a vibrating plate, a spiral track, and a sorting device. The vibrating plate generates vibrations of appropriate frequency and amplitude through an electromagnetic vibrator, so that the titanium nails 7 gradually rise on the spiral track and, under the action of the sorting device, removes the titanium nails 7 that do not meet the specifications, ensuring that the quality and state of the titanium nails 7 entering the guide rod group 52 meet the stapling requirements.

[0084] The material cutting mechanism 53 specifically includes: a lower slide 531, which is slidably connected inside the base plate 51, and the two sides of the lower slide 531 are constructed with slide grooves 532 adapted to the bottom of the guide rod group 52. Through the cooperation of the slide grooves 532 and the bottom of the guide rod group 52, the lower slide 531 can slide smoothly along the direction of the guide rod group 52 to ensure the stability of the subsequent material cutting and pushing action; an upper slide 534, which is limitedly slidably connected to the top of the lower slide 531 in the vertical direction, and a return spring 533 is clamped between the upper slide 534 and the lower slide 531. The return spring 533 has the elastic force to drive the upper slide 534 to move up and away from the lower slide 531. After completing a material cutting and pushing action, the return spring 533 can make the upper slide 534 automatically return to the initial position to ensure the cyclic working performance of the material cutting mechanism 53;

[0085] The one-way push plate 536 is arranged at the top and both sides of the upper slide 534. The one-way push plate 536 is limitedly rotated and connected to the upper slide 534. When the one-way push plate 536 rotates to the maximum stroke in the direction away from the upper slide 534, the end of the one-way push plate 536 and the end of the upper slide 534 are exactly located in the same plane, ensuring that sufficient and stable thrust can be provided when pushing the titanium nail 7, while avoiding unnecessary interference or damage to the titanium nail 7. In addition, a torsion spring is arranged on the rotating shaft of the one-way push plate 536 to drive the one-way push plate 536 away from the upper slide 534. The torsion spring provides a continuous rotation driving force for the one-way push plate 536, so that it can automatically reset after completing the pushing action, so as to perform the next pushing operation. Through the above structural design, the titanium nail 7 is accurately pushed from the guide rod group 52 to the matching groove 541 of the synchronous belt 54, ensuring the smooth supply of the stapling material.

[0086] Furthermore, the one-way push plate 536 is connected to the upper slide 534 by limited rotation. When the one-way push plate 536 rotates to the maximum stroke in the direction away from the upper slide 534, the end of the one-way push plate 536 and the end of the upper slide 534 are located in the same plane. This structure ensures that the one-way push plate 536 can apply a uniform and stable thrust when pushing the titanium nail 7, avoiding the situation where the titanium nail 7 is offset or damaged due to uneven thrust. At the same time, the torsion spring set on the rotating shaft of the one-way push plate 536 to drive the one-way push plate 536 away from the upper slide 534 can ensure that after completing a pushing action, the one-way push plate 536 automatically and quickly returns to the initial position by relying on the torsion of the torsion spring, so as to continuously and efficiently perform the next material pushing operation, thereby ensuring the accuracy, reliability and continuity of the cutting mechanism 53 in pushing the titanium nail 7 during the entire nailing production process.

[0087] The elastic force of the reset spring 533 drives the upper slide 534 to move upward away from the lower slide 531, ensuring that the upper slide 534 can be reset in time and accurately under the action of the elastic force after each material pushing action is completed, so as to maintain the normal circulation working state of the cutting mechanism 53. The top of the guide rod group 52 is provided with a cutting node 521, and in coordination with it, the bottom of the base plate 51 is provided with a sinking groove 511 that matches the cutting node 521. At the same time, the top of the upper slide 534 is also provided with a guide groove 535 that matches the cutting node 521. The cooperation of the sinking groove 511 and the cutting node 521 enables the titanium nails 7 provided by the vibrating feeder 12 to be orderly stacked on one side of the guide rod group 52 and maintain a fixed position without displacement.

[0088] When the cutting mechanism 53 runs on the guide rod group 52 to the side close to the vibrating feeder 12, the cutting node 521 cooperates with the guide groove 535 to make the upper slide 534 move down and close to the lower slide 531. At this time, the one-way push plate 536 is blocked and turned inward and stuck in the gap between the adjacently arranged titanium nails 7. When the cutting mechanism 53 runs on the guide rod group 52 to the side close to the synchronous belt 54, the one-way push plate 536 no longer turns over, thereby driving the titanium nail 7 at the end to move synchronously, so that the titanium nail 7 moves up from the sinking groove 511 and enters the matching groove 541, thereby realizing the precise cutting and stable pushing function of the cutting mechanism 53, ensuring that the titanium nail 7 can smoothly and accurately enter the matching groove 541 of the synchronous belt 54 from the guide rod group 52, thereby ensuring the smooth progress of the entire stapling production process and improving the stapling efficiency and quality.

[0089] The present application realizes the automation of the entire process from the supply and delivery of titanium nails 7 to the final loading into the nail bin 31 through the precise coordination among the stapling roller 4, the driving mechanism 6, the feeding transfer mechanism 5 and the pushing mechanism 9. The vibrating feeder 12 continuously feeds the guide rod group 52, the cutting mechanism 53 conveys the titanium nails 7 in a rhythmic manner and is accurately conveyed to the corresponding position by the synchronous belt 54, and then the pushing mechanism 9 cooperates with the stapling roller 4 and the jig 2 to complete the stapling, which reduces the manual operation links, greatly improves the overall speed of stapling, and can meet the needs of large-scale production.

[0090] The meshing structure of the racks 21 on both sides of the jig 2 and the synchronous gears 41 at both ends of the stapling roller 4 is based on the relationship between the specific number of teeth and the number of nail magazines 31. The number of teeth of the synchronous gears is equal to twice the number of nail magazines in a single nail magazine group, and the number of nail magazines in a single nail magazine group is an odd number, thereby realizing high-precision synchronous movement of the stapling roller 4 and the jig 2 during the stapling process, ensuring that each titanium nail 7 can be accurately aligned and loaded into the corresponding nail magazine 31, avoiding problems such as misalignment and skewness in stapling, and improving the accuracy of the stapling position.

[0091] The first detection contact 821 in the nail sleeve 8 of the present invention can detect in real time whether the titanium nail 7 is accurately installed in the nail sleeve 8; on the other hand, the second detection contact 951 on the detection slider 95 in the pushing mechanism 9 detects the state of the titanium nail 7 again when the titanium nail 7 is pushed to a position close to the stapling position. Through this dual detection mechanism, it can more comprehensively and timely discover the missing nails, titanium nail pushing abnormalities and other situations that may occur during the stapling process, and effectively prevent products with stapling defects from flowing into subsequent processes. Once an abnormal situation is detected, the equipment can stop running immediately and inform the operator of the specific abnormal position through sound and light alarms, display screen prompts and other methods, which is convenient for the operator to quickly locate and solve the problem, thereby ensuring the stapling quality of the product and greatly reducing the medical safety hazards caused by quality problems such as missing nails.

[0092] The above is only the best implementation method adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
