DETAILED DESCRIPTION
[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.
[0033] In some technologies, the automatic bending device for steel needles cannot bend the steel needles after the needle tip bevel is formed, resulting in a long process waiting period, inflexible and inconvenient operation. In order to solve this technical problem, the present application provides an automatic bending device for medical steel needles. The structures of the various parts of the automatic bending device for medical steel needles are described below:
[0034] For example, the needle of the infusion port in the medical equipment is generally bent, and needles with different bending angles are used for different patient parts. Therefore, a medical steel needle automatic bending device is required to make needles with different bending angles; the common steel needle bending equipment in China generally bends the steel needle first, then cuts the bevel of the steel needle, and finally sharpens the steel needle, resulting in that only high-end equipment can be used for production when performing needle bending operations, and the waiting cycle is very inflexible and inconvenient. In response to the above problems, it is necessary to set up a device that can bend the existing straight needle, that is, the steel needle with the needle tip bevel processed, and the straight needle that is being put into production. However, the difficulty of bending the needle after the needle tip bevel is formed is that it is necessary to find a way to ensure the relative degree of the needle tip bevel and the bending angle; and when bending is required, the needle tip must not be damaged, and the steel needle body must be protected. Since the steel needle is a hollow tube, it is extremely easy to flatten the needle tube when bending, so it is also necessary to ensure that the steel needle is not flattened during the bending process.
[0035] Depend on Figure 1 It can be seen that the present application provides an automatic bending device for medical steel needles, comprising: a base 1, a main body device 2 is arranged on the top of the base 1; an upper mold 3, the upper mold 3 is connected to the main body device 2, and is arranged on a side away from the base 1; a lower mold 4, the lower mold 4 is connected to the upper mold 3, and is arranged on a side away from the main body device 2; a first groove 31 is formed between the lower mold 4 and the upper mold 3; a lifting cylinder 5, the lifting cylinder 5 is slidably connected to the main body device 2, and is arranged on one side of the main body device 2; a bending die head 6, the bending die head 6 is connected to the lifting cylinder 5, and is arranged on a side away from the base 1; a second groove 61 is arranged on the side of the bending die head 6 away from the lifting cylinder 5; the first groove 31 and the second groove 61 are used to place the steel needle to be bent.
[0036] The present application provides a medical steel needle automatic bending device, which inserts the steel needle to be bent, i.e., the steel needle whose needle tip bevel has been processed, into the first groove 31 and the second groove 61. When not in operation, the first groove 31 and the second groove 61 are on the same horizontal line, and the steel needle to be bent can be inserted into the first groove 31 and the second groove 61 horizontally. Figure 1 The steel needle to be bent is shown in an unbent state; the steel needle to be bent is started by the lifting cylinder 5 to move in a direction away from the base 1, and the bending work of the steel needle to be bent is completed after the steel needle to be bent is bent to a target angle.
[0037] The present application proposes an automatic bending device for medical steel needles, which greatly improves the efficiency and accuracy of bending medical steel needles. In the initial state, the first groove 31 and the second groove 61 are on the same horizontal line, which facilitates the insertion of the steel needle to be bent; the steel needle to be bent has been processed with a needle tip bevel. Figure 1 As shown, the state A of the steel needle to be bent is that the steel needle to be bent is in the initial state of being unbent, and is placed straight and stably in the two grooves. During the bending process, the lifting cylinder 5 starts to work, and it moves away from the base 1. As the lifting cylinder 5 moves, the two grooves originally located on the same horizontal line begin to displace relative to each other, and this displacement causes the steel needle inserted therein to gradually bend. During this process, the steel needle is bent along a predetermined path under the guidance of the two grooves to ensure the accuracy and consistency of the bending. The key to the bending process is to ensure that the steel needle is bent to the target angle. This target angle is precisely set according to medical needs, and it determines the performance and effect of the steel needle in subsequent use. When the steel needle to be bent is bent to a predetermined angle, the lifting cylinder 5 stops moving. After the lifting cylinder 5 moves toward the base 1 until the first groove 31 and the second groove 61 are on the same horizontal line, the bent steel needle to be bent is taken out, and the bending work of the steel needle to be bent is completed; the bent steel needle to be bent is as shown in FIG. Figure 1 As shown, the state B of the steel needle to be bent is the bent state of the steel needle to be bent.
[0038] Exemplarily, the bending angle of the steel needle to be bent is determined according to the lifting cylinder 5, and the lifting cylinder 5 is provided with a limit position, i.e., a target position. When the lifting cylinder 5 reaches the limit position, it cannot move upward any further, wherein the limit position of each of the lifting cylinders 5 is set in advance and is set according to the required bending angle of the steel needle to be bent; wherein, in the present application, a height sensor and other devices can be set so as to flexibly control the rising height of the lifting cylinder 5 according to different input required bending angles of the steel needle to be bent; it can be understood that there is a certain proportional relationship between the rising height of the lifting cylinder 5 and the angle of the steel needle to be bent, so the bending angle of the steel needle to be bent can be determined according to the above-mentioned proportional relationship and the rising height of the lifting cylinder 5.
[0039] Depend on Figure 1 It can be known that the device further includes: a manual valve 7, which is electrically connected to the lifting cylinder 5; the manual valve 7 is connected to the main device 2 and is arranged on the other side of the main device 2; the manual valve 7 is provided with a first state position and a second state position; when the manual valve 7 is in the first state position, the lifting cylinder 5 moves to the side away from the base 1 until it reaches the target position; when the manual valve 7 is in the second state position, the lifting cylinder 5 moves to the side close to the base 1 until the first groove 31 and the second groove 61 are in the same horizontal direction. When the manual valve 7 is in the first state position, the lifting cylinder 5 is started and moves to the side away from the base 1 until it reaches the target position, which is the limit position; after the steel needle to be bent is bent to the target angle, the manual valve 7 is controlled to be in the second state position, and the lifting cylinder 5 moves in the direction close to the base 1, and the bending work of the steel needle to be bent is completed after the first groove 31 and the second groove 61 are in the same horizontal line.
[0040] Depend on Figure 2 and Figure 3It can be seen that the third groove 32 is provided on the side of the upper mold 3 close to the first groove 31; when the steel needle to be bent is located in the first groove 31, the third groove 32 is located at the tip of the steel needle to be bent. When the steel needle to be bent is located in the first groove 31, the chamfered surface fits the upper mold 3; the width and height of the first groove 31 are equal to the outer diameter of the steel needle to be bent. The width of the second groove 61 is equal to the outer diameter of the steel needle to be bent. It is understandable that the current automatic bending device for medical steel needles can only bend the steel needle first, then cut the bevel of the steel needle, and finally sharpen the steel needle. It is unable to bend the steel needle with a needle tip. The third groove 32 provided in the present application can well protect the needle tip of the steel needle, and prevent the needle tip of the steel needle to be bent from contacting the upper mold 3. When the user places the steel needle to be bent in the first groove 31 and the second groove 61, the needle tip of the steel needle to be bent is immersed in the third groove 32, so that when the steel needle bending work is performed, the steel needle to be bent will not contact the upper mold 3, thereby protecting the needle tip of the steel needle to be bent from deformation.
[0041] Exemplarily, by setting the width and height of the first groove 31 equal to the outer diameter of the steel needle to be bent, when the steel needle to be bent is located in the first groove 31, the beveled surface fits with the upper mold 3. It can be understood that the steel needle to be bent is a hollow cylindrical structure, and the width and height of the first groove 31 are set equal to the outer diameter of the steel needle to be bent, so that the steel needle to be bent will not move in the up and down directions and the left and right directions when it is extended into the first groove 31, thereby ensuring that the steel needle to be bent will not deviate during the bending process; by setting the width of the second groove 61 equal to the outer diameter of the steel needle to be bent, when the lifting cylinder 5 rises during the bending process of the steel needle to be bent, the steel needle to be bent will not move in the left and right directions when it is in the second groove 61, thereby ensuring that the steel needle to be bent will not deviate during the bending process.
[0042] The automatic bending device for medical steel needles provided in the present application ensures the stability and accuracy of the steel needle to be bent during the bending process by means of the groove structure. Specifically, the width and height of the first groove 31 are precisely set to be equal to the outer diameter of the steel needle to be bent; when the steel needle to be bent is inserted into the first groove 31, due to the matching of the width and height, the steel needle will not move in the up and down directions and the left and right directions, which not only ensures the stable position of the steel needle to be bent before bending, but also lays a solid foundation for subsequent bending operations. It is worth noting that the steel needle to be bent is a hollow cylindrical structure, and its beveled surface is in contact with the upper mold 3, ensuring that the beveled surface of the steel needle to be bent can be fully supported and protected during the bending process, thereby avoiding unnecessary damage or deformation during bending. The width of the second groove 61 is also precisely set to be equal to the outer diameter of the steel needle to be bent; during the bending process, when the lifting cylinder 5 starts to rise, it ensures that the steel needle to be bent will not move in the left and right directions, and can effectively prevent the steel needle to be bent from deflecting or moving, thereby ensuring the accuracy and consistency of the bending.
[0043] Depend on Figure 2 and Figure 3 It can be seen that the steel needle to be bent is provided with an oblique cut surface, such as Figure 3 As shown in the figure, the upper mold 3 is provided with a fourth groove 33 on the side close to the first groove 31; when the steel needle to be bent is located in the first groove 31, the fourth groove 33 is located at the turning point of the needle tip of the steel needle to be bent; the turning point of the needle tip is located on the side of the beveled surface away from the needle tip. Since the turning point of the needle tip on the side of the beveled surface away from the needle tip of the steel needle to be bent is a relatively fragile position in the steel needle to be bent, it is easy to be flattened during the bending process. Therefore, the present application provides a fourth groove 33 on the side of the upper mold 3 close to the first groove 31, and the fourth groove 33 is located at the turning point of the needle tip of the steel needle to be bent; when the steel needle to be bent is extended into the first groove 31, the turning point of the needle tip of the steel needle to be bent is immersed in the fourth groove 33, so that during the bending process of the steel needle to be bent, the turning point of the needle tip of the steel needle to be bent will not contact the upper mold 3, thereby protecting the turning point of the needle tip of the steel needle to be bent from being flattened, thereby ensuring the integrity of the steel needle to be bent.
[0044] For example, in the process of automatic bending of medical steel needles, it is crucial to ensure the integrity and structural stability of the steel needle to be bent. In particular, when it comes to the turning point of the needle tip where the beveled surface in the steel needle to be bent is away from the needle tip, this area becomes a relatively fragile part of the entire steel needle due to the particularity of the structure. During the bending process, due to the concentration of force points and the increase in stress, this area is easily flattened or deformed, which will directly affect the use effect and safety of the steel needle. In order to effectively solve this problem, the present application provides a fourth groove 33 on the side of the upper mold 3 close to the first groove 31. Specifically, when the steel needle to be bent extends into the first groove 31, the turning point of its needle tip will naturally sink into the fourth groove 33. In this way, in the subsequent bending process, even if the upper mold 3 applies pressure to the steel needle, the turning point of the needle tip will not directly contact the upper mold 3, thereby avoiding the flattening or deformation of the steel needle to be bent due to pressure; effectively protecting the turning point of the needle tip of the steel needle to be bent, ensuring the integrity and structural stability of the steel needle; secondly, since unnecessary physical contact is avoided, friction and wear during the bending process are reduced, further extending the service life of the steel needle.
[0045] Depend on Figure 1 It can be seen that a support foot 51 is provided on the side of the lifting cylinder 5 close to the base 1; when the first groove 31 and the second groove 61 are in the same horizontal direction, the support foot 51 fits the base 1; an adjustment device 511 is provided on the support foot 51, and the length of the support foot 51 can be adjusted by the adjustment device 511. The support foot 51 is used to position the lifting cylinder 5 so that the first groove 31 and the second groove 61 are in the same horizontal line. It is understandable that after a long period of use of the automatic bending device for medical steel needles, the lifting cylinder 5 will inevitably have a certain offset, so that the first groove 31 and the second groove 61 are not in the same horizontal line, so that the bending work cannot be performed. The user can adjust the length of the support foot 51 through the adjustment device 511 so that the first groove 31 and the second groove 61 are in the same horizontal line, so that the bending work of the steel needle to be bent can be carried out normally, thereby improving the service life of the automatic bending device for medical steel needles.
[0046] Depend on Figure 5It can be known that the upper mold 3 and the lower mold 4 are connected through a fixing plate 34; the upper mold 3 is screwed to the fixing plate 34 through a plurality of first bolts 35, and the lower mold 4 is screwed to the fixing plate 34 through a plurality of second bolts 41. The lower mold 4 is fixed to the main device 2, and the upper mold 3 is fixed to the lower mold 4 through a fixing plate 34. In order to prevent the steel needle to be bent from breaking in the first groove 31 during the bending work, the present application fixes the upper mold 3 and the lower mold 4 through a fixing plate 34. If the steel needle to be bent breaks in the first groove 31, the first bolt 35 can be removed from the fixing plate 34 so that the upper mold 3 can be separated from the lower mold 4, so that the broken steel needle to be bent can be taken out of the first groove 31, and then the upper mold 3 and the lower mold 4 are fixed by the first bolt 35, so as to improve the service life of the medical steel needle automatic bending device.
[0047] Depend on Figure 4 It can be seen that the side of the base 1 away from the main device 2 is provided with an anti-slip strip 11, and the anti-slip strip 11 is relatively arranged along the length direction and the width direction of the base 1. In order to prevent the automatic bending device for medical steel needles from tipping over due to shaking during the bending process, the present application provides an anti-slip strip 11 on the side of the base 1 away from the main device 2, thereby increasing the friction between the base 1 and the desktop, and preventing the automatic bending device for medical steel needles from tipping over due to shaking during the bending process.
[0048] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application.
