Description

Technical Field

[0001] This application relates to the technical field of suture needles with thread, and in particular to a needle and thread assembly device. Background Technology

[0002] Currently, there are two common types of suture needles used in medical practice: The first type resembles a regular sewing needle, with a small hole at the rear end through which the medical suture passes and connects to the needle. A disadvantage of this type is the noticeable suture protrusion at the connection point, which can easily damage the patient's tissues during surgery. The second type is an improvement on the first. Its structure includes a groove at the rear end of the needle. The suture is placed in this groove and then pressed together using a punch press. While this type is an improvement, its production process involves manually cutting the suture to the desired length, hardening both ends, inserting the suture head into the groove at the rear end of the needle, and then pressing the groove together to secure the suture to the needle, thus creating the second type of suture needle. In summary, the production of this type of suture needle still suffers from problems such as the need for manual threading, high scrap rate, and low production efficiency. Utility Model Content

[0003] Therefore, it is necessary to provide a needle and thread assembly device that can improve production efficiency and has adjustable suture length.

[0004] A needle and thread assembly device for attaching suture thread to a suture needle, the needle and thread assembly device comprising:

[0005] A thread supply mechanism for supplying the suture thread;

[0006] A first processing mechanism is capable of reciprocating motion along a first direction. The first processing mechanism includes a curing component for curing a portion of the suture.

[0007] The second processing mechanism is capable of reciprocating along the first direction. The second processing mechanism includes a thread clamping assembly and a thread cutting assembly. The thread cutting assembly is used to disconnect the suture thread, and the thread clamping assembly is used to clamp and drive the suture thread to move a preset distance away from the first processing mechanism.

[0008] Clamping assembly for holding the suture needle;

[0009] The clamping assembly, the second processing mechanism, and the first processing mechanism are arranged sequentially at intervals along a first direction, and the axial direction of the portion of the suture located between the clamping assembly and the first processing mechanism is the same as that of the first direction.

[0010] In one embodiment, the first processing mechanism includes a first base and a first driving member for driving the first base to reciprocate along a first direction. The curing component is disposed on the first base and has a suture opening extending along the first direction. The curing component is capable of generating heat and transferring heat to the suture opening to harden the suture in the suture opening.

[0011] In one embodiment, the first processing mechanism further includes a force measuring component disposed on the first base, the force measuring component being able to clamp the suture and move away from the clamping component under the drive of the first base, so as to detect the tension on the suture.

[0012] In one embodiment, the force measuring component is located on the side of the curing component away from the second processing mechanism.

[0013] In one embodiment, the second processing mechanism includes a second base and a second driving member for driving the second base to reciprocate along a first direction. The wire clamping assembly and the wire cutting assembly are both disposed on the second base. The wire clamping assembly and the wire cutting assembly are arranged along the first direction, and the wire clamping assembly is disposed on the side of the wire cutting assembly close to the first processing mechanism.

[0014] In one embodiment, the first direction is horizontal, and the second processing mechanism further includes a lifting component, which is vertically disposed between the second base and the wire clamping component. The wire cutting component is disposed beside the lifting component along the first direction and connected to the lifting component. The lifting component is used to drive the wire cutting component to move up and down between the wire cutting position and the initial position.

[0015] In one embodiment, when the suture cutting assembly is in the suture cutting position, the height of the suture is within the trimming range of the suture cutting assembly; when the suture cutting assembly is in the initial position, the height of the suture is higher than the top of the suture cutting assembly.

[0016] In one embodiment, the second processing mechanism further includes a limiting component disposed along the first direction on the side of the suture clamping component away from the first processing mechanism, the limiting component having an opening extending along the first direction, through which the suture thread passes.

[0017] In one embodiment, the second processing mechanism further includes a detection component disposed beside the suture clamping component along the first direction, the detection component being used to detect whether the suture is at the target height and to issue a reminder.

[0018] In one embodiment, the needle and thread assembly device further includes a thread guide roller assembly, which is located downstream of the thread supply mechanism and upstream of the first processing mechanism along the direction of movement of the suture line from the thread supply mechanism to the first processing mechanism; the thread guide roller assembly is used to change the height and / or direction of the suture line located between the thread supply mechanism and the first processing mechanism.

[0019] When using the needle and thread assembly device provided in this application to produce needle-loaded sutures, there is no need to pre-cur and cut the suture before connecting it to the needle. This needle and thread assembly device can cure part of the suture while threading it onto the needle, significantly improving production efficiency. Furthermore, by pre-setting a second processing mechanism to move the suture a preset distance away from the first processing mechanism, this preset distance is the length of the suture in each needle-loaded suture, thus adjusting the length of the suture in the needle-loaded suture.

[0039] Please see Figures 1 to 8 This application provides a needle and thread assembly device for connecting a suture 11 to a suture needle. The needle and thread assembly device includes:

[0040] Thread supply mechanism 10 is used to supply suture thread 11;

[0041] The first processing mechanism 20 is capable of reciprocating along the first direction A. The first processing mechanism 20 includes a curing component 21, which is used to cure part of the suture 11.

[0042] The second processing mechanism 30 is capable of reciprocating along the first direction A. The second processing mechanism 30 includes a thread clamping assembly 31 and a thread cutting assembly 32. The thread cutting assembly 32 is used to break the suture 11, and the thread clamping assembly 31 is used to clamp and drive the suture 11 to move a preset distance away from the first processing mechanism 20.

[0043] Clamping assembly (not shown) for holding suture needles;

[0044] The clamp assembly, the second processing mechanism 30 and the first processing mechanism 20 are arranged sequentially at intervals along the first direction A, and the axial direction of the portion of the suture 11 located between the clamp assembly and the first processing mechanism 20 is the same as that of the first direction A.

[0045] It is understood that when using the needle and thread assembly device provided in this application to produce needle-loaded sutures 11, it is not necessary to pre-cur and cut the sutures 11 before connecting them to the suture needle. This needle and thread assembly device can cure part of the sutures 11 while threading them onto the suture needle, greatly improving production efficiency. Furthermore, by pre-setting the second processing mechanism 30 to move the sutures 11 a preset distance away from the first processing mechanism 20, this preset distance is the length of the sutures 11 in each needle-loaded suture 11, which means the length of the sutures 11 in the needle-loaded suture 11 is adjusted.

[0046] The method for attaching the suture 11 to the suture needle using the needle and thread assembly device is as follows:

[0047] It should be noted in advance that when producing the first needle-loaded suture 11, the suture 11 is manually threaded through the suture needle, and then production of the first product begins from step S100 below. Alternatively, with manual assistance, a hardened end is first created on the suture 11, and this end is clamped onto the suture clamping assembly 31 of the second processing mechanism 30. At this time, the second processing mechanism 30 is in the first position mentioned above, and then production of the first product begins from step S500 mentioned above.

[0048] The manufacturing method of this needle and thread assembly device includes:

[0049] S100: The curing component 21 of the first processing mechanism 20 cures a portion of the suture 11 at a first position, so that the suture 11 has a hardened portion.

[0050] Specifically, in the suture assembly device for the suture needle with thread, the suture 11 passes from the thread supply mechanism 10 through the curing component 21 of the first processing mechanism 20. The curing component 21 generates heat to heat the suture 11 inside the curing component 21, so that the suture 11 is hardened to form a hardened part of a certain length.

[0051] The curing component 21 of the first processing mechanism 20 has an operating state and an off state. When the suture 11 needs to be heated and cured, the curing component 21 is opened, that is, in the operating state. When the suture 11 does not need to be heated and cured, the curing component 21 is closed, that is, in the off state. By adjusting the opening time T of the curing component 21 and the movement speed V of the suture 11 in the curing component 21 (i.e., the speed at which the suture 11 passes through the curing component 21), the length H of the hardened part heated and cured by the curing component 21 is equal to T*V, thereby obtaining hardened parts of different lengths.

[0052] It should also be noted that at this time, one end of the suture 11 is located in the suture supply mechanism 10, and the other end is clamped by the clamping component of the second processing mechanism 30 or pressed into the groove at the tail of the suture needle to maintain the tension between the sutures 11.

[0053] S200: The first processing unit 20 moves to a second position away from the second processing unit 30 to expose the hardened part.

[0054] Specifically, at this time, the curing component 21 of the first processing mechanism 20 is in the closed state. And the first processing mechanism 20 moves to the second position along the first direction A away from the second processing mechanism 30, that is, the line connecting the first position and the second position bracket is in the same axial direction as the suture line 11.

[0055] S300: The second processing mechanism 30 moves to the hardened portion, and the wire clamping assembly 31 of the second processing mechanism 30 clamps the end of the hardened portion near the first processing mechanism 20. Similarly, the wire clamping assembly 31 of the second processing mechanism 30 can also clamp the non-cured portion near the hardened portion (the end near the first processing mechanism 20).

[0056] Specifically, the second processing mechanism 30 moves to the hardened part, that is, to the first position in step S100. At this time, the first processing mechanism 20 is located in the second position.

[0057] S400: The thread-cutting assembly 32 of the second processing mechanism 30 breaks the hardened part into the tail end of one suture 11 and the head end of another suture 11. At this time, the thread-clamping assembly 31 of the second processing mechanism 30 clamps the head end of the suture 11.

[0058] It should be noted that the suture-cutting assembly 32 of the second processing mechanism 30 separates the hardened portion into the tail end of one suture 11 and the head end of another suture 11. This means that for each suture needle, each suture 11 has a head end and a tail end with a partially hardened portion. The head end with the hardened portion allows for easier insertion into the suture needle's tail slot, while the tail end prevents the suture 11 from unraveling. Therefore, when the suture-cutting assembly 32 separates the hardened portion, it needs to act at the middle of the hardened portion of the suture 11, so that both the tail end of one suture 11 and the head end of the other suture 11 have a partially hardened portion. 。

[0059] Furthermore, since the suture needle at this point has been connected to the suture thread 11 through the slot at its tail, it is now a suture needle with thread. The clamping assembly will automatically release its grip on the suture needle with thread, and then the suture needle with thread will fall into the material box 50 used to store the suture needle with thread.

[0060] S500: The suture clamping assembly 31 of the second processing mechanism 30 moves the first end of the suture 11 a preset distance and passes into the groove at the tail of the suture needle.

[0061] It should be noted that when the suture clamping assembly 31 of the second processing mechanism 30 moves the first end of the suture 11 a preset distance, the preset distance is slightly greater than the length of the suture 11 required in the suture needle. During this process, the suture supply mechanism 10 keeps the suture 11 under constant tension, which can prevent the suture 11 from being too loose, causing the actual length of the suture 11 to be greater than the preset length, and can also prevent the suture 11 from being too tight, which would break or damage the suture 11. Thus, the preset distance moved by the suture clamping assembly 31 of the second processing mechanism 30 is consistent with the length of the pulled suture 11.

[0062] S600: The tail of the suture needle is slotted to allow the tail of the suture needle to engage with the beginning of the suture 11.

[0063] It is understandable that the above steps are performed cyclically. After completing step S600, the process will return to step S100, thus enabling the production method to continue and further improving the production efficiency of the needle-stitched suture 11.

[0064] It should also be noted that the suture feeding mechanism 10 can use a servo tensioner, which can provide constant tension to the suture 11 when the beginning of the suture 11 is clamped.

[0065] Further, see Figure 2 and Figure 3 The needle and thread assembly device also includes a thread guide roller assembly 12. Along the direction of movement of the suture thread from the thread supply mechanism 10 to the first processing mechanism 20, the thread guide roller assembly 12 is located downstream of the thread supply mechanism 10 and upstream of the first processing mechanism 20. That is, the suture thread 11 reaches the first processing mechanism 20 after passing through the thread guide roller assembly 12 from the thread supply mechanism 10. The thread guide roller assembly 12 is used to change the height and / or direction of a portion of the suture thread 11 located between the thread supply mechanism 10 and the first processing mechanism 20, so that the position of the thread supply mechanism 10 is not limited by the site / factory / workshop and can be arranged arbitrarily, thereby improving the versatility of the needle and thread assembly device.

[0066] Understandably, the thread guide assembly 12 includes at least two thread guides to improve the versatility of the needle and thread assembly device. (Illustrative example, such as...) Figure 2 As shown, the guide roller group 12 in this embodiment includes three guide rollers. In other embodiments, other numbers of guide rollers may also be used.

[0067] In one embodiment, see Figure 2 and Figure 4The first processing mechanism 20 includes a first base 23 and a first driving member (not shown in the figure) for driving the first base 23 to reciprocate along the first direction A. The curing component 21 is disposed on the first base 23. The curing component 21 has a thread opening 22 extending along the first direction A. The curing component 21 can generate heat and transfer the heat to the thread opening 22. In this way, the curing component 21 can heat the suture 11 inside the thread opening 22, so that the suture 11 is hardened to form a hardened part of a certain length.

[0068] In one embodiment, see Figure 3 , Figure 4 and Figure 6 The first processing mechanism 20 also includes a force measuring component 24 disposed on the first base 23. The force measuring component 24 can clamp the suture 11 and move away from the clamping component under the drive of the first base 23 to detect the tension on the suture 11. By detecting whether the tension on the suture 11 reaches a preset tension value, if the preset tension value is reached, it indicates that the fixation strength between the tip and the suture needle meets the standard; if the preset tension value is not reached, it indicates that the fixation strength between the tip and the suture needle does not meet the standard.

[0069] Understandably, if the fixation strength between the suture thread 11 and the suture needle is not up to standard, meaning the suture thread 11 is prone to detaching from the groove at the tail of the suture needle, then the suture needle with the thread is a defective product. By testing whether the fixation strength between the suture thread 11 and the groove at the tail of the suture needle meets the standard, the defect rate of the product can be reduced.

[0070] In this embodiment, the method of using the needle and thread assembly device, after step S600: pressing the groove at the tail of the suture needle to allow the groove at the tail of the suture needle to engage with the beginning end of the suture 11, further includes:

[0071] S700: Check whether the fixing strength of the groove between the beginning end of the suture 11 and the end of the suture needle meets the standard. If it meets the standard, stop the measurement. If it does not meet the standard, check whether the beginning end is discarded. If it is discarded, cut the hardened part on the suture 11 to generate a new beginning end, and then re-clamp the new beginning end in the second processing mechanism 30. If it is not discarded, then re-clamp the beginning end in the second processing mechanism 30.

[0072] Understandably, if the fixing strength between the beginning of the suture 11 and the groove at the end of the suture needle is insufficient, the suture 11 will detach from the groove at the end of the suture needle. In this case, manual intervention is required to determine whether the beginning of the suture 11 is now unusable. Understandably, in step S600, the groove at the end of the suture needle has been pressed shut and cannot be reused; therefore, the suture needle is discarded.

[0073] Furthermore, the method for detecting whether the tension on the suture 11 reaches the preset tension value is as follows: the force measuring component 24 of the first processing mechanism 20 clamps the suture 11 and tightens the suture 11 to detect the tension on the suture 11.

[0074] Understandably, at this point, the tip of the suture 11 is pressed into the groove at the tail of the suture needle (the groove at the tail of the suture needle has been deformed by the pressing), meaning the suture needle clamps the tip of the suture 11, and the suture clamping assembly 31 of the second processing mechanism 30 does not clamp the suture 11. After the force measuring assembly 24 clamps the suture 11, the suture located between the suture needle and the force measuring assembly 24 is not subjected to any other external forces. This avoids interference from other external forces with the tension on the suture 11, thereby improving the accuracy of the force measuring assembly 24 in measuring the tension value on the suture 11.

[0075] It is also understood that in this embodiment, the tension value on the suture 11 is detected by pulling the suture 11 away from the suture needle, thereby detecting whether the fixation strength between the tip of the suture 11 and the suture needle meets the standard. Specifically, if the fixation strength between the tip of the suture 11 and the suture needle meets the standard, when the force measuring component 24 of the first processing mechanism 20 clamps the suture 11 and pulls the suture 11 away from the suture needle, the tip of the suture 11 will not fall out of the groove at the tail of the suture needle. At this time, the force measuring component 24 of the first processing mechanism 20 only provides the suture 11 with a tendency to move away from the suture needle, and will not produce obvious displacement. However, if the fixing strength between the tip of the suture 11 and the suture needle is insufficient, when the force measuring component 24 of the first processing mechanism 20 clamps the suture 11 and pulls it away from the suture needle, the tip of the suture 11 will detach from the groove at the tail of the suture needle. At this time, since there is no tension between the suture 11 and the suture needle, the force measuring component 24 of the first processing mechanism 20 will drive the suture 11 to move away from the suture needle along the first direction A, and generate displacement. In one embodiment, see... Figure 4 The force measuring component 24 is located on the side of the curing component 21 away from the second processing mechanism 30. Thus, when the first processing mechanism 20 needs to move from the first position in step S100 to the second position in step S200 to expose the hardened portion, since the force measuring component 24 is located on the side of the curing component 21 away from the second processing mechanism 30, it does not occupy the moving distance of the first processing mechanism 20. Therefore, the moving distance of the first processing mechanism 20 is smaller, which is beneficial to improving production efficiency.

[0076] In one embodiment, see Figure 3 , Figure 5 , Figure 7 and Figure 8The second processing mechanism 30 includes a second base 33 and a second driving member (not shown in the figure) for driving the second base 33 to reciprocate along a first direction A. Both the wire clamping assembly 31 and the wire cutting assembly 32 are disposed on the second base 33, so that when the second base 33 moves along the first direction A, the wire clamping assembly 31 and the wire cutting assembly 32 can maintain synchronous movement. Furthermore, the wire clamping assembly 31 and the wire cutting assembly 32 are arranged along the first direction A, with the wire clamping assembly 31 located on the side of the wire cutting assembly 32 closer to the first processing mechanism 20. Thus, when the wire clamping assembly 31 clamps the hardened portion near the end of the first processing mechanism 20, the wire cutting assembly 32 can cut the hardened portion from its middle position.

[0077] For illustrative purposes only, see below. Figure 1 The needle and thread assembly device also includes a worktable 40 and a slide rail 41 disposed on the worktable 40. The slide rail 41 is arranged along a first direction A. The first base 23 and the second base 33 are both disposed on the slide rail 41. This reduces the frictional force when the first base 23 and the second base 33 move, and also reduces the torque requirements and load on the first and second driving components. Schematic, both the first and second driving components are motors.

[0078] In one embodiment, see Figure 2 , Figure 5 and Figure 8 The first direction A is horizontal. The second processing mechanism 30 also includes a lifting component 34. The lifting component 34 is disposed between the second base 33 and the wire clamping component 31 along the vertical direction B. The wire cutting component 32 is disposed beside the lifting component 34 along the first direction A and is connected to the lifting component 34. The lifting component 34 is used to drive the wire cutting component 32 to rise and fall between the wire cutting position and the initial position.

[0079] Understandably, in the height direction of the second processing mechanism 30, i.e., in the vertical direction B, the suture cutting assembly 32 can change its height relative to the suture clamping assembly 31 under the drive of the lifting assembly 34. When it is necessary to cut the hardened portion on the suture 11, the lifting assembly 34 drives the suture cutting assembly 32 to move upward from the initial position to the suture cutting position, so that the cutter on the suture cutting assembly 32 can cut the hardened portion on the suture 11. After the trimming is completed, the lifting assembly 34 drives the suture cutting assembly 32 to move downward from the suture cutting position back to the initial position, thereby preventing the suture cutting assembly 32 from interfering with the movement of the suture 11.

[0080] Furthermore, when the thread-cutting assembly 32 is in the thread-cutting position, the height of the suture 11 is within the trimming range of the thread-cutting assembly 32. This ensures that the blade on the thread-cutting assembly 32 can cut the hardened portion of the suture 11. When the thread-cutting assembly 32 is in the initial position, the height of the suture 11 is higher than the top of the thread-cutting assembly 32. This prevents the thread-cutting assembly 32 from interfering with the movement of the suture 11. Specifically, the trimming range of the thread-cutting assembly 32 is the range between the top and bottom of the blade on the thread-cutting assembly 32.

[0081] In one embodiment, see Figure 5 and Figure 8 The second processing mechanism 30 also includes a limiting component 35, which is disposed along a first direction on the side of the suture clamping component 31 away from the first processing mechanism 20. The limiting component 35 has an opening extending along the first direction, through which the suture 11 passes. In this way, the horizontal height and axial position of the tip of the suture 11 can be maintained, preventing the tip of the suture 11 from shifting when inserted into the groove at the tail of the suture needle, thereby improving the accuracy of inserting the tip of the suture 11 into the groove at the tail of the suture needle.

[0082] In one embodiment, see Figure 5 and Figure 8 The second processing mechanism 30 also includes a detection component 36, which is disposed beside the suture clamping component 31 along the first direction. The detection component 36 is used to detect whether the suture 11 is at the target height and to issue a reminder. It should be noted that the target height is the height at which the tip of the suture 11 can be inserted into the groove at the tail of the suture needle. When the suture 11 is at the target height, its tip can be accurately inserted into the groove at the tail of the suture needle, thereby improving the yield rate of this needle and thread assembly method.

[0083] Understandably, if the suture 11 is positioned too high or too low, it will affect the accuracy of inserting the first end of the suture 11 into the groove at the tail of the suture needle in step S500, resulting in the suture needle and suture 11 not being fixed or not fixed tightly, generating waste and wasting production materials. When the suture 11 falls off the suture needle or the suture clamping assembly 31 of the second processing mechanism 30, or when the suture 11 is positioned too high or too low, the detection assembly 36 will issue a warning and stop the working steps in the above production method. In this way, the yield rate of the suture 11 with needle can be improved.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application.
