Description

Technical Field

[0001] This application relates to the field of surgical suture manufacturing technology, and in particular to a tension control method, device, electronic device, and computer-readable storage medium. Background Technology

[0002] Surgical sutures are special threads used in surgery for ligation, suturing, and tissue repair. Surgical sutures include barbed sutures, which 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.

[0003] In the production of barbed sutures, barbs need to be cut into the original surgical sutures. During the barb formation process, it is necessary to ensure that the clamping equipment exerts tension on the surgical suture to keep it taut. However, in the production process of related technologies, the tension on the surgical suture cannot be adjusted, which leads to a decrease in the suture's tautness or even suture breakage, resulting in lower quality of the subsequently produced barbed sutures. 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 tension control method, device, electronic device, and computer-readable storage medium, which enables the tension value of the clamping mechanism on the surgical suture to be within a preset range, so as to ensure that the surgical suture is taut and does not break.

[0006] The method includes:

[0007] Control at least two of the clamping mechanisms to clamp the two ends of the surgical suture respectively;

[0008] During the barb cutting process of surgical sutures, the tension sensor obtains the tension value of the clamping mechanism on the surgical suture, and based on the tension value, controls the drive mechanism to drive one of the clamping mechanisms to move closer to or further away from the other clamping mechanism, so that the tension value is within a preset range.

[0009] The tension control method according to the embodiments of this application has at least the following beneficial effects: The tension control method of this application can be applied to the tension control equipment of the barbed suture production system. First, the two ends of the surgical suture are clamped by the two clamping mechanisms respectively, so that the surgical suture is kept suspended, so that the barb-cutting mechanism of the barbed suture production system can perform barb-cutting processing on the surgical suture. In addition, during the barb-cutting process of the surgical suture, the tension value of the clamping mechanism on the surgical suture is obtained by the tension sensor, and the driving mechanism is controlled based on the tension value to drive one of the clamping mechanisms to move closer to or away from the other clamping mechanism, so that the tension value is within a preset range, so as to ensure that the surgical suture is in a taut state and does not break, thereby ensuring the quality of the produced barbed suture.

[0013] If the tensile force value is detected to be within the preset range, a response command is sent to the barb-cutting mechanism so that the barb-cutting mechanism performs the barb-cutting operation based on the response command.

[0024] The adjustment distance is determined based on the tension difference;

[0025] The drive mechanism is controlled to move one of the clamping mechanisms away from the other clamping mechanism by an adjustment distance.

[0028]

[0029] Where D is the adjustment distance, F is the tension difference, E is the elastic modulus of the surgical suture material, A is the equivalent cross-sectional area of ​​the surgical suture, and α is the creep coefficient of the surgical suture material.

[0030] According to some embodiments of this application, the equivalent cross-sectional area is obtained through the following steps:

[0031] The equivalent cross-sectional area is calculated using the cross-sectional area formula, which is:

[0032]

[0052] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0053] In the description of this application, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0054] In the description of this application, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0055] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0056] In the description of this application, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0057] In the production of barbed sutures, barbs need to be cut into the original surgical suture to form barbs. During barb formation, the suture must be kept taut. However, some technologies involve forming barbs on the original suture, such as unidirectional, bidirectional, or spiral barbs. This reduces the cross-sectional area of ​​the barbed section, creating localized weak points and lowering the suture's effective stiffness. Furthermore, the clamping structure holding the suture in these technologies is fixed in position, meaning the suture length remains constant. This reduces the tension on the suture, further decreasing its tautness and negatively impacting the subsequent barb formation process, resulting in lower-quality barbed sutures. Other existing technologies manually adjust the suture tension, which can lead to excessive deformation and breakage, also resulting in lower-quality barbed sutures.

[0058] Based on this, embodiments of this application provide a tension control method, device, electronic device, and computer-readable storage medium, which can keep the tension value of the clamping mechanism on the surgical suture within a preset range to ensure that the surgical suture is taut and does not break, thereby ensuring the quality of the barbed suture.

[0059] Reference Figure 1 , Figure 1 This is a schematic diagram of the tension control device according to an embodiment of this application. The tension control device includes a drive mechanism 200, at least two clamping mechanisms 100, and a tension sensor (not shown in the figure). The tension sensor is disposed in one of the clamping mechanisms. The tension sensor is used to detect the tension value of the clamping mechanism 100 on the surgical suture; the drive mechanism 200 is connected to at least one clamping mechanism 100, and the drive mechanism 200 is used to drive the at least two clamping mechanisms 100 to move closer to or further away from each other;

[0060] It should be noted that the tension control device in this application embodiment is applied to a barbed suture production system. The barbed suture production system is used to process surgical sutures to obtain barbed sutures. The barbed suture production system may include a barbed cutting mechanism for performing barb cutting operations to form barbs on the surgical sutures. This application embodiment does not specifically limit the structure of the barbed suture production system and the structure of the barbed cutting mechanism.

[0061] Those skilled in the art can determine the specific number of clamping mechanisms 100 according to actual needs. In some embodiments, refer to Figure 1 In some embodiments, the number of clamping mechanisms 100 is two, and both clamping mechanisms 100 are mounted on the driving mechanism 200. The driving mechanism 200 drives the two clamping mechanisms 100 to move, enabling the two clamping mechanisms 100 to move closer to or further away from each other. In other embodiments, some clamping mechanisms 100 are independent of the driving mechanism 200 and are not connected to each other, while other clamping mechanisms 100 are mounted on the driving mechanism 200. For example, the number of clamping mechanisms 100 is two, one of which is mounted on the driving mechanism 200, while the other is not connected to the driving mechanism 200. The driving mechanism 200 can drive the clamping mechanism 100 mounted on the driving mechanism 200 to move closer to or further away from the other clamping mechanism 100, thereby enabling the two clamping mechanisms 100 to move closer to or further away from each other.

[0062] It should be noted that the drive mechanism 200 is a linear drive mechanism 200. The drive mechanism 200 can be a motor-driven gear and rack mechanism or a motor-driven lead screw mechanism. This application does not make any specific limitation in this regard.

[0063] It should be noted that the clamping mechanism 100 may consist of clamping plates and a thumb cylinder. The thumb cylinder drives the clamping plates to move closer or further apart, thereby clamping the surgical sutures. This application does not limit the specific structure of the clamping mechanism 100.

[0064] based on Figure 1The illustrated tension control device illustrates a tension control method according to a first aspect of this application. The tension control method provided in this application can be applied to a terminal, a server, or software running on either a terminal or a server. In some embodiments, the terminal can be a smartphone, tablet, laptop, desktop computer, embedded device, etc.; the server can be configured as an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms; the software can be an application implementing the tension control method, but is not limited to the above forms.

[0065] This application can be used in a wide variety of general-purpose or special-purpose computer system environments or configurations. Examples include: personal computers, server computers, handheld or portable devices, tablet devices, multiprocessor systems, microprocessor-based systems, set-top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, and distributed computing environments including any of the above systems or devices. This application can be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, etc., that perform specific tasks or implement specific abstract data types. This application can also be practiced in distributed computing environments where tasks are performed by remote processing devices connected via a communication network. In distributed computing environments, program modules can reside in local and remote computer storage media, including storage devices.

[0066] Reference Figure 2 , Figure 2 This is a schematic flowchart illustrating the steps of the tension control method according to an embodiment of this application. The tension control method according to an embodiment of this application includes, but is not limited to, steps S210 and S220.

[0067] Step S210: Control at least two clamping mechanisms to clamp the two ends of the surgical suture respectively;

[0068] In step S220, during the barb cutting process of the surgical suture, the tension value of the clamping mechanism on the surgical suture is obtained by the tension sensor, and the drive mechanism is controlled based on the tension value to drive one clamping mechanism to move closer to or away from another clamping mechanism so that the tension value is within a preset range.

[0069] The tension control method of this application embodiment, through steps S210 to S220, firstly, uses two clamping mechanisms 100 to clamp both ends of the surgical suture, respectively, to keep the surgical suture suspended, so that the barb-cutting mechanism of the barb suture production system can perform barb-cutting processing on the surgical suture. Furthermore, during the barb-cutting process of the surgical suture, the tension value of the clamping mechanism 100 on the surgical suture is obtained by the tension sensor, and based on the tension value, the driving mechanism 200 is controlled to drive one of the clamping mechanisms 100 to move closer to or away from the other clamping mechanism 100, so that the tension value is within a preset range, thereby ensuring that the surgical suture is in a taut state and does not break, thus ensuring the quality of the produced barb suture.

[0070] It should be noted that those skilled in the art can set preset ranges according to actual conditions, such as setting preset ranges based on the material and length of surgical sutures.

[0071] In some embodiments, refer to Figure 3 , Figure 3 for Figure 2 A schematic diagram of a specific process for step S220. Step S220 may include, but is not limited to, steps 310 to S330.

[0072] Step S310: In response to receiving an operation request command sent by the barb cutting mechanism, the tension value is obtained through the tension sensor;

[0073] Step S320: If the tension value is detected to be outside the preset range, the drive mechanism is controlled based on the tension value to drive one clamping mechanism to move closer to or further away from another clamping mechanism so that the tension value is within the preset range.

[0074] Step S330: When the detected tension value is within the preset range, a response command is sent to the barb cutting mechanism so that the barb cutting mechanism performs the barb cutting operation based on the response command.

[0075] It is worth noting that in the barbed suture production system, the barb-cutting mechanism and the tension control device are communicatively connected. For example, both the barb-cutting mechanism and the tension control device are equipped with communication modules. The barb-cutting mechanism sends operation request commands to the tension control device through the communication module, and the tension control device sends response commands to the barb-cutting mechanism through the communication module. It should be noted that this application does not specifically limit the communication module; for example, the communication module can be a Bluetooth module, a Wi-Fi module, or other network modules.

[0076] Specifically, through steps S310 to S330, before performing the barb-cutting operation, the barb-cutting mechanism sends an operation request command to the tension control device. Upon receiving the operation request command, the tension control device acquires the tension value through a tension sensor. If the tension value is detected to be outside the preset range, the drive mechanism 200 brings the tension value within the preset range. If the tension value is detected to be within the preset range, a response command is sent to the barb-cutting mechanism, causing the barb-cutting mechanism to perform the barb-cutting operation based on the response command. In this way, before performing the barb-cutting operation, the tension value is checked to ensure it is within the preset range. Only when the tension value is within the preset range will the barb-cutting mechanism perform the operation, ensuring that the tension value remains within the preset range during each barb-cutting operation, thus guaranteeing that the surgical suture remains taut and does not break.

[0077] It should be noted that the barb-cutting operation is used to form barbs on surgical sutures, and only one barb is formed in a single barb-cutting operation. This application does not limit the specific actions of the barb-cutting operation; the specific actions of the barb-cutting operation are based on the specific structure of the barb-cutting mechanism, and this application does not limit the specific structure of the barb-cutting mechanism.

[0078] In some embodiments, refer to Figure 4 , Figure 4 for Figure 3 A schematic diagram of a specific process for step S320. Step S320 may include, but is not limited to, steps S410 to S430.

[0079] Step S410: Obtain the current number of barbs on the surgical suture;

[0080] Step S420: Determine the target tensile force range from a preset range based on the current number of barbs;

[0081] Step S430: Control the drive mechanism to drive one clamping mechanism to move closer to or further away from another clamping mechanism so that the tension value is within the target tension range.

[0082] It is worth noting that the cross-sectional area of ​​the barb-forming section in the surgical suture is smaller than the nominal cross-sectional area of ​​the suture body, creating local weak points that reduce the effective stiffness of the suture and lower the tensile strength. However, the tensile strength required to keep the suture taut and perform barb-cutting operations also changes. Those skilled in the art can test surgical sutures with different numbers of barbs, testing the tensile strength range suitable for barb-cutting operations for each suture, thereby establishing a first mapping relationship between the number of barbs and the tensile strength range. Thus, in step S420, after obtaining the current number of barbs, a tensile strength range matching the current number of barbs can be selected from the first mapping relationship as the target tensile strength range. When the tensile strength of the clamping mechanism 100 on the current surgical suture with the current number of barbs is within the target tensile strength range, the current surgical suture can be kept taut without breaking, ensuring the effectiveness of the barb-cutting operation and thus guaranteeing the quality of the barb suture.

[0083] It is worth noting that, in this embodiment of the application, the target tension range is determined based on the current number of barbs through steps S410 and S430, thereby dynamically adjusting the tension value of the clamping mechanism 100 for surgical sutures with different numbers of barbs. During the processing, the surgical sutures are kept taut and do not break, thus ensuring the quality of the barbed sutures.

[0084] It should be noted that the nominal cross-sectional area refers to the theoretical cross-sectional area of ​​the surgical suture before any processing, and is usually calculated based on the nominal diameter of the suture.

[0085] In some embodiments, the operation request instruction includes the number of times the barb-cutting mechanism performs its barb-cutting operation; see reference Figure 5 , Figure 5 for Figure 4 A schematic diagram of a specific process for step S410. Step S410 may include, but is not limited to, steps S510 and S520.

[0086] Step S510: Extract the execution count from the operation request instruction;

[0087] Step S520: Determine the current number of barbs based on the number of executions and the preset number of barbs for the surgical suture.

[0088] Specifically, the preset barb quantity refers to the number of barbs in a finished barbed thread, and the execution count refers to the total number of times the barb-cutting mechanism performs the barb-cutting operation throughout the entire processing. After obtaining the execution count, the execution count is used as the dividend, and the preset barb quantity is used as the divisor to perform a division operation, obtaining the quotient and remainder. The quotient is the quantity of finished barbed thread, and the remainder is the current barb quantity. For example, a = bq + r, where a is the execution count, b is the preset barb quantity, q is the quantity of finished barbed thread, and r is the current barb quantity.

[0089] In some embodiments, refer to Figure 6 , Figure 6 for Figure 4 A schematic diagram of a specific process for step S430. Step S430 may include, but is not limited to, steps S610 to S630.

[0090] Step S610: If the tension value is lower than the lower limit of the target tension range, calculate the tension difference between the tension value and the lower limit of the target tension range.

[0091] For example, if the target tension range is [j, k] and the tension value is f, then the tension difference is jf.

[0092] Step S620: Determine the adjustment distance based on the tension difference;

[0093] Step S630: Control the drive mechanism to drive one clamping mechanism to move an adjustment distance away from the other clamping mechanism.

[0094] It is worth noting that, in this embodiment of the application, by determining the adjustment distance based on the tension difference through steps S610 and S630, the drive mechanism 200 is controlled to drive one clamping mechanism 100 to move the adjustment distance away from the other clamping mechanism 100, which can reduce the risk of surgical suture breakage due to excessive movement of the clamping mechanism 100.

[0095] In some embodiments, determining the adjustment distance based on the tension difference includes:

[0096] The adjustment distance is calculated using the distance calculation formula, which is:

[0097]

[0098] Where D is the adjustment distance, F is the tension difference, E is the elastic modulus of the surgical suture material, A is the equivalent cross-sectional area of ​​the surgical suture, and α is the creep coefficient of the surgical suture material.

[0099] It is worth noting that by using the distance calculation formula, and combining elastic deformation compensation and creep deformation compensation, the adjustment distance obtained is relatively accurate. This ensures that after the control drive mechanism 200 drives one clamping mechanism 100 to move the adjustment distance away from the other clamping mechanism 100, the tension value is within the target tension range, and the risk of surgical suture breakage due to excessive movement of the clamping mechanism 100 is reduced.

[0100] In some embodiments, the equivalent cross-sectional area is obtained through the following steps:

[0101] The equivalent cross-sectional area is calculated using the cross-sectional area formula, which is:

[0102]

[0103] Where A is the equivalent cross-sectional area, X is the current number of barbs, Y is the length of the barbs, A1 is the cross-sectional area of ​​the barb-forming section in the surgical suture, and A2 is the nominal cross-sectional area of ​​the surgical suture body.

[0104] Specifically, the formation of barbs on surgical sutures, usually bidirectional barbs, means that barbs are present on both opposite sides of the surgical suture. This leads to a reduction in the cross-sectional area of ​​the barb-forming section in the surgical suture. Therefore, calculating the equivalent cross-sectional area using the cross-sectional area formula can improve the accuracy of the adjustment distance obtained in subsequent calculations.

[0105] A second aspect of this application provides a tension control device, applied to... Figure 1 A schematic diagram of a tension control device. (Refer to...)

[0108] The tension control device of this application embodiment is used to execute the tension control method of the first aspect embodiment. When executing the method, the two ends of the surgical suture are clamped by the two clamping mechanisms 100 respectively, so that the surgical suture is kept suspended, so that the barb cutting mechanism of the barb suture production system can perform barb cutting processing on the surgical suture. During the barb cutting process of the surgical suture, the tension value of the clamping mechanism 100 on the surgical suture is obtained by the tension sensor, and the driving mechanism 200 is controlled based on the tension value to drive one of the clamping mechanisms 100 to move closer to or away from the other clamping mechanism 100, so that the tension value is within a preset range, so as to ensure that the surgical suture is in a taut state and does not break, thereby ensuring the quality of the produced barb suture.
