Description

Technical Field

[0001] This application relates to the field of medical surgical suture production technology, and in particular to a barbed suture production device. Background Technology

[0002] Surgical sutures are specialized threads used in surgery for ligation, suturing, and tissue repair. Their selection and application are crucial for surgical success and postoperative recovery. Barbed sutures are knotless sutures with barbed structures on their surface. These barbs penetrate the tissue during suturing, locking the suture in place and achieving wound closure without the need for knots. This design allows barbed sutures to maintain appropriate tension during surgery, preventing tissue slippage and effectively shortening suturing time. They are particularly suitable for minimally invasive surgical procedures such as laparoscopy, reducing the use of forceps and improving efficiency.

[0003] In the production process of barbed sutures, barbs need to be formed on both sides of the surgical suture. The current production method is to set barb cutting modules on both sides of the surgical suture, with two barb cutting modules forming barbs on one side of the surgical suture respectively. This production method is relatively expensive. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a barbed suture production device capable of automating the production of barbed sutures at a low cost.

[0005] The first aspect of this application provides a barbed suture production apparatus, comprising:

[0006] The feeding mechanism is used to transport surgical sutures;

[0008] A suture cutting mechanism is provided between the feeding mechanism and the clamping and rotating mechanism, and the suture cutting mechanism is used to cut surgical sutures located between the feeding mechanism and the clamping and rotating mechanism;

[0009] A barb-cutting mechanism is used to cut barbs on surgical sutures to form barbs on the sutures.

[0010] The barbed suture production equipment according to the first aspect of this application has at least the following beneficial effects: During operation, the barbed suture production equipment of this application has a feeding mechanism that transports surgical sutures. After passing through a suture cutting mechanism, the sutures are transported to a clamping and rotating mechanism, so that both ends of the sutures are clamped by different clamping and rotating mechanisms to keep the sutures taut. At this time, the suture cutting mechanism cuts the surgical suture located between the feeding mechanism and the clamping and rotating mechanism. When the surgical suture is taut, a barb-cutting mechanism performs a barb-cutting operation on the suture to form barbs. After forming barbs on one side of the suture, the clamping and rotating mechanism rotates the suture so that the barb-cutting mechanism can form barbs on the other side of the suture. Thus, this application can use only one barb-cutting mechanism to form barbs on both sides of the surgical suture, which can reduce production costs; and before the barb-cutting mechanism works, the surgical suture located between the feeding mechanism and the clamping and rotating mechanism is cut by the suture cutting mechanism, so as to avoid the feeding mechanism affecting the working process of the barb-cutting mechanism and ensure the quality of the barb suture produced.

[0050] Reference Figures 1 to 9 , Figure 1This is a schematic diagram of the structure of a barbed suture production device according to an embodiment of this application. The barbed suture production device according to this application includes a feeding mechanism, at least two clamping and rotating mechanisms 400, a suture cutting mechanism 600, and a barb cutting mechanism 500. The feeding mechanism is used to transport surgical sutures; the clamping and rotating mechanisms 400 are used to clamp or release the surgical sutures transported by the feeding mechanism, and also to rotate the surgical sutures; the suture cutting mechanism 600 is disposed between the feeding mechanism and the clamping and rotating mechanisms 400, and is used to cut the surgical sutures located between the feeding mechanism and the clamping and rotating mechanisms 400; the barb cutting mechanism 500 is used to perform a barb cutting operation on the surgical sutures to form barbs on the surgical sutures.

[0051] In the operation of the barbed suture production equipment of this embodiment, the feeding mechanism conveys surgical sutures. After passing through the suture cutting mechanism 600, the sutures are conveyed to the clamping and rotating mechanism 400, so that both ends of the surgical sutures are clamped by different clamping and rotating mechanisms 400 to keep the surgical sutures taut. At this time, the suture cutting mechanism 600 cuts the surgical suture located between the feeding mechanism and the clamping and rotating mechanism 400. When the surgical sutures are taut, the barb cutting mechanism 500 performs a barb cutting operation on the surgical sutures to form barbs on the surgical sutures. After barbs are formed on one side of the surgical sutures, the clamping and rotating mechanism 400 rotates the surgical sutures so that the barb cutting mechanism 500 can form barbs on the other side of the surgical sutures. Thus, this application can form barbs on both sides of the surgical suture using only one barb-cutting mechanism 500, which can reduce production costs; and before the barb-cutting mechanism 500 works, the surgical suture located between the feeding mechanism and the clamping and rotating mechanism 400 is cut by the suture cutting mechanism 600, so as to avoid the feeding mechanism affecting the working process of the barb-cutting mechanism 500 and ensure the quality of the barbed suture produced.

[0052] In some embodiments, the barbed suture production equipment further includes a first drive mechanism 200, which is connected to at least one clamping rotation mechanism 400. The first drive mechanism 200 is used to drive one clamping rotation mechanism 400 to move closer to or away from another clamping rotation mechanism 400.

[0053] In some embodiments, the barbed suture production equipment further includes a second drive mechanism 300, and a barb-cutting mechanism 500 is connected to the second drive mechanism 300. The second drive mechanism 300 is used to drive the barb-cutting mechanism 500 to move between at least two clamping and rotating mechanisms 400.

[0054] Specifically, the feeding mechanism conveys the surgical suture. After passing through the suture cutting mechanism 600, the suture is conveyed to the clamping and rotating mechanism 400. At this time, the first driving mechanism 200 drives at least one clamping and rotating mechanism 400 to move, so that at least two clamping and rotating mechanisms 400 clamp the surgical suture, with each end of the suture being clamped by a different clamping and rotating mechanism 400. Then, the first driving mechanism 200 drives the at least two clamping and rotating mechanisms 400 to move away from each other, and controls the two clamping and rotating mechanisms 400 to maintain a tendency to move away from each other, so that the surgical suture remains taut. At this time, the suture cutting mechanism 600 cuts the surgical suture located between the feeding mechanism and the clamping and rotating mechanism 400. When the surgical suture is taut, the barb-cutting mechanism 500 performs a barb-cutting operation on the surgical suture to form barbs on the surgical suture. Each time the barb-cutting mechanism 500 performs a barb-cutting operation, the second drive mechanism 300 drives the barb-cutting mechanism 500 to move between at least two clamping and rotating mechanisms 400 to form barbs at different positions on the surgical suture. Thus, the barbed suture production equipment of this application embodiment can automatically produce barbed sutures. Compared with the traditional production method where the surgical suture is moved after each barb is cut to form a barb, in this application, the barb-cutting mechanism 500 is driven by the second drive mechanism 300 to move between at least two clamping and rotating mechanisms 400 each time it performs a barb-cutting operation. This allows the surgical suture to remain taut throughout the production process without needing to adjust its position, thereby improving production efficiency while ensuring quality. Furthermore, multiple barb-cutting mechanisms 500 can work simultaneously to further improve production efficiency. Before the barb-cutting mechanism 500 operates, the surgical suture located between the feeding mechanism and the clamping and rotating mechanism 400 is cut by the suture cutting mechanism 600, preventing the feeding mechanism from affecting the working process of the barb-cutting mechanism 500 and ensuring the quality of the produced barbed sutures.

[0055] In some embodiments, during the cutting process of the barb-cutting mechanism 500, barbs may form on the surgical suture, causing the suture to lose its tautness and resulting in poor quality barb sutures. Therefore, during production, after a predetermined number of new barbs are formed on the surgical suture, the first driving mechanism 200 drives at least two clamping and rotating mechanisms 400 to move a predetermined distance in mutually distancing directions, ensuring that the surgical suture remains taut and thus guaranteeing the production quality of the barb sutures. Those skilled in the art can set the predetermined number and predetermined distance according to actual conditions.

[0056] In some embodiments, the feeding mechanism is used to transport surgical sutures. The feeding mechanism may include a feeding shaft and a drive motor, which drives a direction shaft to transport the surgical sutures. This application does not limit the specific structure of the feeding mechanism, as long as it can transport surgical sutures.

[0057] It should be noted that the number of clamping and rotating mechanisms 400 is at least two, and those skilled in the art can set the specific number of clamping and rotating mechanisms 400 according to actual needs. In some embodiments, refer to Figure 1 In some embodiments, the number of clamping rotating mechanisms 400 is two, and both clamping rotating mechanisms 400 are mounted on the first driving mechanism 200. The first driving mechanism 200 drives the two clamping rotating mechanisms 400 to move, enabling the two clamping rotating mechanisms 400 to move closer to or further away from each other. In other embodiments, some clamping rotating mechanisms 400 are independent of the first driving mechanism 200 and are not connected to each other, while other clamping rotating mechanisms 400 are mounted on the first driving mechanism 200. For example, the number of clamping rotating mechanisms 400 is two, one of which is mounted on the first driving mechanism 200, while the other is not connected to the first driving mechanism 200. The first driving mechanism 200 can drive the clamping rotating mechanism 400 mounted on the first driving mechanism 200 to move closer to or further away from the other clamping rotating mechanism 400, thereby enabling the two clamping rotating mechanisms 400 to move closer to or further away from each other.

[0058] In some embodiments, the clamping rotation mechanism 400 is further provided with a tension sensor (not shown in the figure), which is used to detect the tension of the clamping rotation mechanism 400 on the surgical suture. For example, when the number of clamping rotation mechanisms 400 is two, the specific control steps of the tension control device in this embodiment are as follows:

[0059] When both clamping and rotating mechanisms 400 are holding the surgical suture, the suture cutting mechanism 600 cuts the surgical suture located between the clamping and rotating mechanism 400 and the feeding mechanism.

[0060] The first drive mechanism 200 is controlled to drive one clamping and rotating mechanism 400 away from another clamping and rotating mechanism 400, and to obtain the tension value of the surgical suture; wherein, the tension value is obtained by detecting a tension sensor;

[0061] When the tension value is detected to be within the preset range, the first drive mechanism 200 is controlled to keep the distance between the two clamping rotation mechanisms 400 constant.

[0062] During the process of the barb-cutting mechanism 500 cutting barbs on the surgical suture, after each barb-cutting operation is completed, the tension value is re-acquired, and the distance between the two clamping and rotating mechanisms 400 is adjusted by the first drive mechanism 200 until the tension value is within the preset range. When the tension value is within the preset range, the next barb-cutting operation is performed on the surgical suture.

[0063] It should be noted that the above steps ensure the surgical sutures remain taut and maintain tension during the suture-cutting process, thus guaranteeing the suture's tautness. This application does not specifically limit the preset range; those skilled in the art can set the preset range according to actual conditions.

[0064] In some embodiments, refer to Figure 1 The barbed suture production equipment also includes a base 100. A first drive mechanism 200 and a second drive mechanism 300 are both mounted on the base 100, and the first drive mechanism 200 and the second drive mechanism 300 are parallel to each other. Two clamping and rotating mechanisms 400 are both mounted on the first drive mechanism 200. The first drive mechanism 200 can drive the two clamping and rotating mechanisms 400 to perform linear reciprocating motion, allowing them to move closer to or further apart. The second drive mechanism 300 can drive a barb-cutting mechanism 500 to perform linear reciprocating motion, allowing the barb-cutting mechanism 500 to move between the two clamping and rotating mechanisms 400, enabling it to perform barb-cutting operations at different positions on the surgical suture.

[0065] In some embodiments, refer to Figure 2 and Figure 3 The barb-cutting mechanism 500 includes a first mounting base 510, a first connecting base 520, a first rotary drive 530, a first linear drive 531, and a barb cutter 532. The first mounting base 510 is slidably mounted on the second drive mechanism 300. The first rotary drive 530 and the first connecting base 520 are both mounted on the first mounting base 510, and the first rotary drive 530 is connected to the first connecting base 520. The first linear drive 531 is mounted on the first connecting base 520, and the barb cutter 532 is movably mounted on the first linear drive 531. The barb cutter 532 is located between at least two clamping and rotating mechanisms 400. The first linear drive 531 is used to drive the barb cutter 532 to perform linear reciprocating motion so that the barb cutter 532 approaches or moves away from the surgical suture. The first rotary drive 530 is used to drive the first connecting base 520 to rotate the barb cutter 532.

[0066] It is worth noting that when the barb-cutting mechanism 500 is running, the first rotary drive 530 first drives the first connecting seat 520 to rotate, thereby driving the barb cutter 532 and the first linear drive 531 to rotate, so that the barb cutter 532 is equivalent to the surgical suture tilting. Then, the first linear drive 531 drives the barb cutter 532 to approach the surgical suture and cut into the surgical suture. At this time, the first linear drive 531 stops running, while the first rotary drive 530 drives the first connecting seat 520 to rotate, thereby driving the barb cutter 532 to rotate. As the barb cutter 532 rotates, it causes the cut part in the surgical suture to flip over, forming a barb. After the barb is formed, the first linear drive 531 drives the barb cutter 532 away from the surgical suture, thus completing the barb-cutting operation. Each time a barb-cutting operation is performed, the second drive mechanism 300 drives the first mounting base 510 to move between at least two clamping and rotating mechanisms 400 to change the relative position of the barb cutter 532 and the surgical suture, thereby enabling the barb-cutting operation to be performed at different positions of the surgical suture.

[0067] In one embodiment, the first connecting seat 520 is circular, and the driving direction of the first linear drive member 531 is radial to the first connecting seat 520.

[0068] In some embodiments, the first linear drive 531 is a drive cylinder, and the first rotary drive 530 is a drive motor. The first connecting seat 520 can be directly connected to the drive end of the first rotary drive 530, or it can be connected to the drive end of the first rotary drive 530 via a transmission belt.

[0069] In some embodiments, a third drive mechanism 900 is also included. The first mounting base 510 is mounted on the second drive mechanism 300 via the third drive mechanism 900. The third drive mechanism 900 is used to drive the first mounting base 510 to perform linear reciprocating motion. The driving direction of the third drive mechanism 900 is perpendicular to the driving direction of the second drive mechanism 300.

[0070] It is worth noting that the third drive mechanism 900 can drive the first mounting base 510 to move closer to or further away from the first drive mechanism 200, and the second drive mechanism 300 drives the third drive mechanism 900 to move between at least two clamping and rotating mechanisms 400, so that the third drive mechanism 900 drives the first mounting base 510 to move between at least two clamping and rotating mechanisms 400. The driving direction of the third drive mechanism 900 is perpendicular to the driving direction of the second drive mechanism 300. Through the second drive mechanism 300 and the third drive mechanism 900, the first mounting base 510 can be driven to move in multiple directions, thereby facilitating the adjustment of the position of the barbed cutter 532.

[0071] It should be noted that both the first drive mechanism 200 and the second drive mechanism 300 are linear drive mechanisms. Linear drive mechanisms can be driven by a motor-driven gear and rack mechanism or by a motor-driven lead screw mechanism. This application does not make any specific limitations on this.

[0072] In some embodiments, the barb-cutting mechanism 500 further includes a prism 540 and a vision sensor 541. Both the prism 540 and the vision sensor 541 are mounted on the first mounting base 510, with the prism 540 located on one side of the barb cutter 532 and the vision sensor 541 located above the prism 540. Specifically, the prism 540 is positioned on one side of the barb cutter 532, such that the surgical suture is located between the prism 540 and the barb cutter 532. The prism 540 can reflect the image of the surgical suture and the barb cutter 532 to the vision sensor 541, enabling the vision sensor 541 to capture the image of the surgical suture and the barb cutter 532, while avoiding obstruction of the barb cutter 532 by the prism 540.

[0073] In one embodiment, the vision sensor 541 is communicatively connected to a preset terminal, transmitting the captured images to the preset terminal so that relevant personnel can observe the images through the preset terminal to observe the specific operation process of the barbed cutter 532. The preset terminal can be a computer, mobile phone, laptop, embedded device, or other device of the relevant personnel, and this application does not make specific limitations in this regard.

[0074] In some embodiments, refer to Figure 2 and Figure 3 The barb-cutting mechanism 500 also includes an auxiliary mechanism, which includes a first clamping component 550 and a second clamping component 560. The first clamping component 550 and the second clamping component 560 are disposed opposite to each other on the first mounting base 510, and both the first clamping component 550 and the second clamping component 560 are located on one side of the barb cutter 532. The first clamping component 550 and the second clamping component 560 are respectively used to clamp or release surgical sutures.

[0075] Specifically, the first clamping component 550 and the second clamping component 560 are located below one side of the first connecting seat 520. When the barbed cutter 532 approaches the surgical suture, the first clamping component 550 and the second clamping component 560 clamp the surgical suture respectively, which can further enhance the tension of the surgical suture. During the barbed cutter 532's barb-cutting operation, the barbed cutter 532 cuts the surgical suture located between the first clamping component 550 and the second clamping component 560. This can reduce the vibration of the surgical suture and ensure the quality of the produced barbed suture.

[0076] In some embodiments, the first clamping assembly 550 includes a first clamping drive and two first clamping plates. The first clamping drive is used to drive the two first clamping plates to move closer to each other or further apart. When the two first clamping plates move closer to each other, they abut against each other, thereby clamping the surgical suture. The first clamping drive may be a drive cylinder.

[0077] In some embodiments, the second clamping assembly 560 includes a second clamping drive and two second clamping plates. The second clamping drive is used to drive the two second clamping plates to move closer to each other or further apart. When the two second clamping plates move closer to each other, they abut against each other, thereby clamping the surgical suture. The second clamping drive may be a drive cylinder.

[0078] In some embodiments, the auxiliary mechanism further includes a support member 572 and a second linear drive member, the second linear drive member being mounted on the first mounting base 510; the support member 572 is connected to the second linear drive member and is located between the first clamping assembly 550 and the second clamping assembly 560; the second linear drive member is used to drive the support member 572 to perform lifting and lowering movements so that the support member 572 supports the surgical sutures clamped by the first clamping assembly 550 and the second clamping assembly 560.

[0079] Specifically, the second linear drive is driven vertically, and it drives the support 572 to move up and down. Before the barb cutter 532 performs the barb-cutting operation, the second linear drive locks the support 572, allowing it to support the surgical suture held by the first clamping assembly 550 and the second clamping assembly 560. Then, the barb cutter 532 cuts the barbs from the portion of the suture supported by the support 572. The support of the support 572 reduces the deformation of the surgical suture, thus ensuring the quality of the produced barb suture. In one embodiment, the second linear drive is a drive cylinder.

[0080] In some embodiments, refer to Figure 4 and Figure 5 The clamping and rotating mechanism 400 includes a second connecting seat 420, a third clamping assembly, and a fourth clamping assembly. The second connecting seat 420 is slidably mounted on the first driving mechanism 200. The third clamping assembly includes a third clamping drive member 430 and two third clamping pieces 431. The third clamping drive member 430 is mounted on the second connecting seat 420 and is used to drive the two third clamping pieces 431 to move closer or further apart. The fourth clamping assembly includes a fourth clamping drive member 440 and two fourth clamping pieces 441. The fourth clamping drive member 440 is mounted on the second connecting seat 420 and is used to drive the two fourth clamping pieces 441 to move closer or further apart. The movement direction of the third clamping pieces 431 is perpendicular to the movement direction of the fourth clamping pieces 441.

[0081] It is worth noting that the use of two third clips 431 and two fourth clips 441 to hold the surgical suture ensures a stable clamping, thereby guaranteeing the tension applied to the suture and maintaining its tautness. Since the movement directions of the third clips 431 and the fourth clips 441 are perpendicular, the positions where the two third clips 431 clamp the suture are different from those where the two fourth clips 441 clamp it. Furthermore, the clamping forces exerted by the two third clips 431 and the two fourth clips 441 on the suture are also perpendicular to each other, further ensuring the suture is firmly clamped and reducing the risk of the suture detaching from the clamping and rotating mechanism 400 during processing.

[0082] In some embodiments, the fourth clamping drive 440 is a drive cylinder, and the two fourth clamping plates 441 are both movable clamping plates. The two fourth clamping plates 441 are installed in the fourth clamping drive 440. The fourth clamping drive 440 is used to drive the two fourth clamping plates 441 to move closer to each other or further away from each other. When the two fourth clamping plates 441 move closer to each other, they abut against each other, thereby clamping the surgical suture. When the two fourth clamping plates 441 move further away from each other, the surgical suture is released.

[0083] In other embodiments, one of the two fourth clips 441 is a movable clip and the other is a fixed clip. The fourth clip 441, which is a fixed clip, is fixed relative to the second connecting seat 420. The fourth clip 441, which is a movable clip, is installed on the third clamping drive member 430. The fourth clamping drive member 440 is used to drive the two to approach and abut against each other, thereby achieving clamping of the surgical suture.

[0084] In some embodiments, the third clamping drive 430 is a drive cylinder, and the two third clamping pieces 431 are both movable clamping pieces. The two third clamping pieces 431 are installed in the third clamping drive 430. The third clamping drive 430 is used to drive the two third clamping pieces 431 to move closer to each other or further away from each other. When the two third clamping pieces 431 move closer to each other, they abut against each other, thereby clamping the surgical suture. When the two third clamping pieces 431 move further away from each other, the surgical suture is released.

[0085] In other embodiments, one of the two third clips 431 is a movable clip and the other is a fixed clip. The fixed clip 431 is fixed relative to the second connecting seat 420, and the movable clip 431 is installed on the third clamping drive member 430. The third clamping drive member 430 is used to drive the two to approach and abut against each other, thereby clamping the surgical suture.

[0086] In some embodiments, the clamping rotation mechanism 400 further includes a second mounting base 410 and a second rotation drive member 450. A second connecting base 420 is movably mounted on the second mounting base 410, and the second mounting base 410 is slidably mounted on the first drive mechanism 200. The second rotation drive member 450 is mounted on the second mounting base 410 and connected to the second connecting base 420. The second rotation drive member 450 is used to drive the second connecting base 420 to rotate.

[0087] It is worth noting that the second rotary drive 450 can be a rotary motor, and the second connecting seat 420 can be directly connected to the drive end of the rotary motor, or the second connecting seat 420 can be connected to the drive end of the rotary motor via a transmission belt. The second rotary drive 450 is used to drive the second connecting seat 420 to rotate the third clamping drive 430 and the fourth clamping drive 440, thereby driving the surgical suture to rotate. In some embodiments, it is necessary to form spiral barbs on the surgical suture, thus requiring the suture to rotate. This application can both ensure the tension on the surgical suture and enable the suture to rotate, reducing the complexity of the equipment and helping to reduce production costs while ensuring production quality.

[0088] In some embodiments, the second connecting seat 420 is provided with a first through hole 421 for surgical sutures to pass through, and the third clamping drive member 430 is provided with a second through hole (not shown in the figure) for surgical sutures to pass through. The first through hole 421 and the second through hole are coaxially arranged, and the second through hole is located on one side between the two third clamping pieces 431.

[0089] Specifically, since the surgical suture is held by at least two clamping and rotating mechanisms 400, when the feeding mechanism feeds the surgical suture to one clamping and rotating mechanism 400, one of the clamping and rotating mechanisms 400 may obstruct the feeding of the surgical suture. Therefore, a first through hole 421 and a second through hole are provided, allowing the surgical suture to pass through both the first through hole 421 and the second through hole, so that the surgical suture can pass through one clamping and rotating mechanism 400 and be clamped by the other clamping and rotating mechanism 400. Furthermore, the second through hole is located on one side between the two third clamping plates 431, so that the surgical suture passing through the second through hole is located between the two third clamping plates 431, thereby facilitating the clamping of the surgical suture by the two third clamping plates 431 when they are close to each other.

[0090] It is worth noting that the second through hole is also located on one side between the two fourth clips 441, so that the surgical suture passing through the second through hole is located between the two fourth clips 441, thereby facilitating the clamping of the surgical suture by the two fourth clips 441 when they are close to each other.

[0091] In some embodiments, the third clamping drive 430 is mounted on the second connecting seat 420 via a connector. The connector is provided with a through groove for the surgical suture to pass through, and the through groove is coaxially arranged with the second through hole and the first through hole 421, so that the surgical suture can pass through the first through hole 421, the through groove and the second through hole, thereby avoiding the connector from obstructing the surgical suture.

[0092] In some embodiments, the clamping and rotating mechanisms 400 are positioned at the same height relative to the surgical suture, meaning the third clamping piece 431 of each clamping and rotating mechanism 400 is positioned at the same height relative to the surgical suture. This ensures that both ends of the surgical suture are at the same height, resulting in a horizontally positioned surgical suture. Because the surgical suture is horizontally positioned, it facilitates processing operations. In some embodiments, height refers to the vertical distance relative to the ground; in other embodiments, height refers to the vertical distance relative to the first driving mechanism 200.

[0093] In some embodiments, refer to Figure 6 The suture cutting mechanism 600 includes a cutting assembly, which includes a first cutting drive 610, a first cutter 621, and a baffle 630. The first cutter 621 is disposed opposite to the baffle 630 and is located between the feeding mechanism and the clamping and rotating mechanism 400. The first cutting drive 610 is disposed on one side of the second driving mechanism 300 and is connected to the first cutter 621. The first cutting drive 610 is used to drive the first cutter 621 to move closer to or away from the baffle 630 to cut the surgical suture located between the baffle 630 and the first cutter 621.

[0094] Specifically, after the surgical suture is clamped by at least two clamping and rotating mechanisms 400, the first cutting drive 610 drives the first cutter 621 to approach the baffle 630 to cut the surgical suture located between the baffle 630 and the first cutter 621, thereby severing the connection between the surgical suture and the feeding mechanism and avoiding the feeding mechanism from affecting the tension of the surgical suture.

[0095] In one embodiment, reference is made to Figure 6The first cutting drive 610 is a drive cylinder. The cutting assembly also includes a third mounting base 620. The first cutter 621 is mounted on the third mounting base 620, which is installed in the first cutting drive 610. The baffle 630 has a through-hole 631 corresponding to the first cutter 621. When the first cutting drive 610 drives the first cutter 621 closer to the baffle 630, the first cutter 621 passes through the through-hole 631. The thread cutting mechanism 600 also includes a push block 622, which is mounted on the third mounting base 620 via an elastic element. The push block 622 is located on one side of the first cutter 621, and the distance between the push block 622 and the baffle 630 is less than the distance between the first cutter 621 and the baffle 630. During cutting, the first cutting drive 610 drives the third mounting base 620 to move the first cutter 621 and the pusher block 622 toward the baffle 630. During this movement, the pusher block 622 first contacts the surgical suture, and the pusher block 622 and the baffle 630 clamp the surgical suture. Then, the first cutter 621 contacts the surgical suture and cuts it. Before the first cutter 621 contacts the surgical suture, the pusher block 622 and the baffle 630 clamp the surgical suture to prevent it from vibrating and to facilitate cutting.

[0096] In one embodiment, the suture cutting mechanism 600 further includes a fifth clamping assembly, which includes a fifth clamping drive 640 and two fifth clamping pieces 641. The two fifth clamping pieces 641 are located on opposite sides of the surgical suture. The fifth clamping drive 640 is mounted on a third mounting base 620 and is used to drive the two fifth clamping pieces 641 to move closer to or further away from each other.

[0097] Specifically, before the first cutter 621 cuts, the second fifth clamping plate 641 is driven by the fifth clamping drive 640 to clamp the surgical suture, and then the first cutter 621 cuts it. In this way, the surgical suture can be clamped tightly to avoid the surgical suture from shaking and to facilitate cutting. Furthermore, the first cutter 621 is located between the fifth clamping plate 641 and the clamping rotation mechanism 400. Therefore, after the surgical suture is cut, since the surgical suture near the feeding mechanism is clamped by the second fifth clamping plate 641, the risk of the surgical suture getting entangled with other structures of the barbed suture production equipment can be reduced.

[0098] In some embodiments, the fifth clamping drive 640 is a drive cylinder, and the two fifth clamping plates 641 are both movable clamping plates. The two fifth clamping plates 641 are installed in the fifth clamping drive 640. The fifth clamping drive 640 is used to drive the two fifth clamping plates 641 to move closer to each other or further away from each other. When the two fifth clamping plates 641 move closer to each other, they abut against each other, thereby clamping the surgical suture. When the two fifth clamping plates 641 move further away from each other, the surgical suture is released.

[0099] In other embodiments, one of the two fifth clips 641 is a movable clip and the other is a fixed clip. The fifth clip 641, which is a fixed clip, is fixed relative to the fifth clamping drive member 640. The fifth clip 641, which is a movable clip, is installed on the fifth clamping drive member 640. The fifth clamping drive member 640 is used to drive the fifth clip 641, which is a movable clip, to move closer to or away from the fifth clip 641, which is a fixed clip, so that the two abut against each other, thereby clamping the surgical suture.

[0100] In some embodiments of this application, the barbed thread production equipment further includes a feeding mechanism 700, referred to... Figure 7 , Figure 8 and Figure 9 The feeding mechanism 700 includes a rotating shaft 710, a third rotary drive 720, and at least two feeding assemblies 730. The rotating shaft 710 is located on one side of the second drive mechanism 300. The feeding assembly 730 includes a fourth mounting base 731 and a sixth clamping assembly. The fourth mounting bases 731 of the two feeding assemblies 730 are spaced apart from the rotating shaft 710, and the sixth clamping assembly is mounted on the fourth mounting base 731. The sixth clamping assembly is used to clamp or release the surgical suture. The third rotary drive 720 is connected to the rotating shaft 710 and is used to drive the rotating shaft 710 to rotate the fourth mounting base 731, so as to move the sixth clamping assembly closer to or away from the surgical suture.

[0101] Specifically, the third rotary drive 720 drives the rotating shaft 710 to rotate, which in turn drives the sixth clamping assembly to rotate. This causes the fourth mounting base 731 of the sixth clamping assembly to bring the clamping assembly closer to the barbed seam, and the barbed seam is clamped by the sixth clamping assembly. After the barbed seam is clamped, the third rotary drive 720 drives the rotating shaft 710 to rotate, which causes the sixth clamping assembly to move away, thereby unloading the material.

[0102] In some embodiments, the feeding mechanism 700 includes a storage tray 800, which is located below one side of the rotating shaft 710. After clamping the barbed suture, the third rotary drive member 720 drives the rotating shaft 710 to rotate, causing the sixth clamping assembly to approach the storage tray 800. After the sixth clamping assembly approaches the storage tray 800, the barbed suture is released through the sixth clamping assembly, causing the barbed suture to fall into the storage tray 800. Thus, the surgical suture feeding device of this embodiment realizes automatic feeding of surgical sutures, improving production efficiency.

[0103] In some embodiments, the third rotary drive 720 is a rotary motor.

[0104] In some embodiments, there are multiple sixth clamping components, which are spaced apart along the axial direction of the rotating shaft 710100. In related art feeding devices, typically only one sixth clamping component is used to clamp the middle of the surgical suture, which can easily lead to the ends of the suture becoming entangled with other structures, or the suture becoming entangled with the sixth clamping component, making feeding impossible. This application, by using multiple sixth clamping components, can simultaneously clamp multiple parts of the surgical suture, reducing the risk of suture entanglement.

[0105] In some implementations, the sixth clamping assembly includes a sixth clamping drive 732 and two sixth clamping plates 733. The sixth clamping drive 732 is a cylinder, and the two sixth clamping plates 733 are movable clamping blocks. The sixth clamping drive 732 is capable of driving the two sixth clamping plates 733 to move closer together and further apart. In another embodiment, one of the two sixth clamping plates 733 is a movable clamping plate, and the other is a fixed clamping plate fixed relative to the sixth clamping drive 732.

[0106] In some embodiments, one of the two sixth clips 733 is provided with a second cutter 734, and the other is provided with a slot 735 that matches the second cutter 734. The sixth clamping drive 732 is used to drive the two sixth clips 733 to move closer or further apart from each other. When the two sixth clips 733 move closer to each other, the second cutter 734 is inserted into the slot 735.

[0107] Specifically, because the two ends of the barbed suture are clamped by the clamping and rotating mechanism 400, the clamped portion cannot form a barb. Therefore, the unprocessable ends need to be cut off. In related technologies, this is usually done manually, which is very inefficient. In this application, however, there are two sixth clamping components. During feeding, the two sixth clamping components clamp the two ends of the surgical suture respectively. When the two sixth clamping pieces 733 approach each other, the second cutter 734 is inserted into the slot 735 and cuts the surgical suture. This achieves automated cutting, improving production efficiency.

[0108] In some embodiments, the sixth clamping assembly further includes a first abutment and at least two second pushers. The first pusher and the second pushers are both mounted on one side of the sixth clamping block provided with the second cutter 734, and the first pusher and the second pushers are both opposite to the slot 735. The second cutter 734 is mounted on the side of the first pusher facing the slot 735, and the at least two second pushers are respectively located on opposite sides of the first pusher.

[0109] It is worth noting that when the two sixth clamping pieces 733 approach each other, the first pusher and the second pusher gradually approach the slot 735, and the second pusher abuts against the sixth clamping piece 733 with the slot 735, thereby clamping the barbed thread. The second cutter 734 moves with the first pusher, inserting into the slot 735 and cutting off the end of the barbed thread. Because the second pusher is located on opposite sides of the first pusher and clamps the barbed thread, even if the second cutter 734 cuts off the end of the barbed thread, the barbed thread will not detach from the sixth clamping assembly, and the waste material from the cut barbed thread will not detach from the sixth clamping assembly, preventing the waste material from affecting other structures. During the subsequent release of the sixth clamping assembly, the barbed thread cut by the second cutter 734 and the waste material fall together into the storage tray 800.

[0110] In some embodiments, refer to Figure 10 and Figure 11 The feeding mechanism includes a housing and a suture delivery assembly. The housing is filled with inert gas and has a suture outlet hole on its first side wall. The housing is used to hold the suture bundle. The suture delivery assembly is used to drive the surgical suture in the suture bundle to be output from the suture outlet hole.

[0111] Specifically, the suture bundle is placed inside the housing 1000, which is filled with inert gas to reduce the risk of oxidation of the surgical sutures in the suture bundle. The first side wall of the housing 1000 is provided with a suture outlet hole through which the surgical suture passes. The suture bundle is connected to the suture delivery assembly, which can drive the surgical suture in the suture bundle to be output from the suture outlet hole. The output surgical suture is then transported to the clamping and rotating mechanism 400 after passing through the suture cutting mechanism 600.

[0112] It is worth noting that the housing 1000 is a sealed structure and has an internal cavity filled with inert gas, and the wire bundle is placed inside the cavity of the housing 1000. Figure 10 The illustrated housing 1000 is a cuboid shape, which is just an example and should not be construed as a limitation of this application. The housing 1000 can also be other shapes, such as a cylinder.

[0113] In some embodiments, the inert gas may be one or more of nitrogen, argon, helium, neon, krypton, and xenon. This application does not specifically limit the inert gas.

[0114] In some embodiments, the wire feeding mechanism is located inside the housing 1000; while in other embodiments, the wire feeding mechanism is located outside the housing 1000.

[0115] In some embodiments, an air intake structure (not shown in the figure) is also provided on one side wall of the housing 1000 to inject inert gas into the housing 1000. This application does not specifically limit the air intake structure, and those skilled in the art can set the air intake structure according to actual needs, for example, the air intake structure is a valve body.

[0116] In some embodiments, refer to Figure 11 It also includes a housing 1100, the second side wall of the housing 1100 is provided with an opening 1111, and the housing 1100 is movably connected to the second side wall. The housing 1100 can move relative to the second side wall to open or close the opening 1111.

[0117] Specifically, the housing 1100 is movable from the second sidewall so that the housing 1100 can open the opening 1111 to place the wire bundle inside the housing 1000, and the housing 1100 can close the opening 1111 to seal the housing 1000 and prevent the inert gas from leaving the housing 1000.

[0118] In some embodiments, the housing 1100 and the second sidewall are detachably connected, for example, by means of detachable screws. In other examples, the housing 1100 and the second sidewall are not detachable, for example, one side of the housing 1100 is hinged to the second sidewall so that the housing 1100 can rotate relative to the second sidewall, thereby opening or closing the opening 1111.

[0119] In some embodiments, the side of housing 1100 opposite to housing 1000 is provided with a recess or a protrusion, which facilitates user control of the rotation of housing 1100 relative to the second sidewall. The protrusion may be a handle.

[0120] In some embodiments, the first sidewall and the second sidewall are different sidewalls in the housing 1000; while in other embodiments, the first sidewall and the second sidewall are the same sidewall in the housing 1000.

[0121] In some embodiments, the second sidewall is provided with a groove 110 that matches the housing 1100, the housing 1100 is movably connected to the groove 110, and the opening 1111 is provided on the bottom wall of the groove 110.

[0122] Specifically, the cross-sectional area of ​​the groove 110 matches the cross-sectional area of ​​the housing 1100, so that the housing 1100 can fit over the groove 110 and seal the opening 1111, thereby sealing the housing 1000. In one embodiment, one side of the housing 1100 is hinged to one side wall of the groove 110, so that the housing 1100 can rotate relative to the side wall of the groove 110, thereby opening or closing the opening 1111.

[0123] In some embodiments, the housing 1100 is a transparent article. For example, the transparent article is glass or a transparent acrylic sheet. Because the housing 1100 is a transparent article, the user can observe the interior of the housing 1000 through the housing 1100, thereby observing the condition of the wire bundle.

[0124] In some embodiments, refer to Figure 11 The suture assembly includes a suture feeder 1320 and a servo tensioner 1310. Both the suture feeder 1320 and the servo tensioner 1310 are mounted on the inner side wall of the housing 1000. The suture feeder 1320 is used to hold the suture bundle, and the servo tensioner 1310 is used to drive the surgical suture in the suture bundle to be output from the suture outlet hole.

[0125] It is worth noting that the servo tensioner 1310 is an instrument used to precisely control the tension of materials during winding, unwinding, or transmission. Its core function is to ensure that the material (e.g., surgical suture) maintains a constant tension by dynamically adjusting the torque of the drive or braking system to drive the material (surgical suture) to move. This application does not specifically limit the servo tensioner 1310; those skilled in the art can select the servo tensioner 1310 according to actual conditions. Specifically, the suture bundle is sleeved in the unwinding shaft 1320, and the surgical suture in the suture bundle is connected to the servo tensioner 1310. After passing through the servo tensioner 1310, the surgical suture passes through the suture exit hole. Tension is applied to the surgical suture by the servo tensioner 1310 to drive the surgical suture in the suture bundle to exit from the suture exit hole.

[0126] In some embodiments, the feed assembly further includes at least one limiting plate 1321, which is mounted on the feed shaft 1320.

[0127] In one embodiment, one end of the wire feeding shaft 1320 is installed on the inner side wall of the housing 1000, and the other end is suspended. There is one limiting plate 1321, which is installed on the suspended end of the wire feeding shaft 1320. The wire bundle is located between the limiting plate 1321 and the inner side wall of the housing 1000. The limiting plate 1321 is used to limit the wire bundle and prevent the wire bundle from falling off the wire feeding shaft 1320.

[0128] In other embodiments, the number of limiting plates 1321 is 2, and the two limiting plates 1321 are spaced apart on the wire feeding shaft 1320, with the wire bundle located between the two limiting plates 1321.

[0129] It should be noted that the limiting plate 1321 and the pay-off shaft 1320 are detachably connected, and the limiting plate 1321 and the pay-off shaft 1320 are relatively fixed. For example, the limiting plate 1321 and the pay-off shaft 1320 are threaded together.

[0130] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
